Work Plan for Supplemental Remedial Investigation for Line I (Including Historical Site Assessment) -IAAAP

EXECUTIVE SUMMARY

Purpose

The purpose of the site investigation is to identify and delineate areas of contamination at Line 1to support remedial designs to remove contaminated material.

This work plan for supplemental remedial investigation for Line 1 at the Iowa ArmyAmmunition Plant (IAAAP) was prepared by T N & Associates, Inc. (TN&A) for the U.S. ArmyCorps of Engineers (USACE) Omaha District under contract No. DACA~-97-D-OO15, DeliveryOrder No. 16.

Data Quality Objectives

The data quality objectives used for the Line 1 work plan, which includes sampling and analysis,were developed to support the subsequent remedial design for contaminated areas at Line 1. Thefollowing bulleted items summarize the data quality objectives for the investigations at Line 1:

• Identify targeted sampling locations based on information from historical data that supportsthe reasonable possibility of releases that could have resulted in soil, sediment, or surfacewater contamination in excess of risk-based action levels.

• Where appropriate, use field test kits for explosives, both trinitrotoluene (TNT)-relatedcompounds and the Royal Demolition Explosive (RDX)/ High Melting Explosive (HMX)type compounds, to determine the presence of explosives at sufficient concentration towarrant follow-up sampling and analysis at a laboratory.

• At targeted sampling locations, collect a sufficient number of samples and analyze them forthe appropriate target analytes, based on past operations, to support remedial designs for eacharea.

Approach to Sampling Design

To prepare the sampling strategy, TN&A divided Line 1 into areas based on physical layout,similarity of past operations, expected types of releases, and possible migration pathways.TN&A identifies the expected types of contaminants for each area and the types of possiblereleases, i.e., releases to soil, surface water, or air.

Line 1 was divided into the following areas for sampling:

• Melt Buildings• Machining Buildings• Storage and Material Inspection Buildings• Component Rest Houses• X-ray Buildings• Research and Development Buildings• Filter Buildings• Drainage Ways and Impoundments• Other Areas of Environmental Concern

Line 1 Work Plan for Supplemental Rl.doc - 9/2012001 Page iExecutive Summary

Work Plan for Supplemental Remedial Investigation for Line I (Including Historical Site Assessment) - IAAAP

TN&A selected specific sampling locations based on the physical layout, degree of uncertaintyin the supporting historical infonnation, the reported past practices and operations, andprofessional judgment. Where historical infonnation was clear and the possible releases narrowlydefined, sampling locations tended to be fewer. Where historical infonnation was unclear orcontradictory, the number of sampling locations tended to be more numerous and widespread.

Approach to Sample Analysis Design

To achieve the data quality objectives for the Line I investigations, TN&A will use fieldscreening techniques for explosives and established off-site laboratory analytical methods forselected parameters.

Field screening for explosives will be used to indicate the presence of explosives, refine thetarget sampling areas, find boundaries of explosives-contaminated areas, and conserve fieldsamples collected for off-site analysis.

At each selected sampling location, soil and sediment samples will be collected and sent off sitefor analysis. The type of analysis for each sample was selected based on the historicalinfonnation relevant to each sampling location. For example:

• Samples from areas where conventional explosives and primers may have been released willbe analyzed for explosives and metals because of the possible lead and mercury in primermaterial.

• Similarly, where atomic weapons assembly materials were possibly released, samples will beanalyzed for explosives, metals (because of the possible barium and boron in specialtyexplosives).

TN&A tailored the analytical program for the soil and sediment samples according to theinfonnation gained from reviewing historical infonnation.

Summary of Sampling and Analysis

The soil and sediment sampling areas and locations are shown on several maps in the "Figures"section of this document.

The amount of soil samples planned for each analytical parameter is summarized in Table ES-l.This analytical program is detailed in the text.

Background for lAAAP Line 1

IAAAP (originally called the Iowa Ordnance Plant) is an active, government-owned, contractoroperated (GOCO) facility engaged in the loading, assembling, and packaging (LAP) of largescale ammunition, including projectiles, mortar rounds, mines, and warheads. IAAAP has severalLAP operations lines and ammunition storage yards spread across over 19,000 acres.Constructed in 1941, Line 1 was the first production line in service at IAAAP. Line 1 isapproximately 1 mile long, covers 173 acres, and encompasses over 250 buildings and relatedfacilities.

From 1941 until August 1945, production at Line 1 included many types of ammunition,including fixed artillery rounds and bombs, in support ofWorld War II. In 1945, Line 1 wascleaned and placed in extended storage status. In 1947, the Atomic Energy Commission (AEC)contracted with Black and Veatch Consultants and Engineers to design facilities at Line 1 foratomic bomb assembly. Existing Line 1 buildings were modified and new facilities constructedto support the atomic weapons production operations.

In 1947, operations at Line 1 resumed under the authority of AEC. AEC operated Line 1 for theassembly of several models of atomic bombs from 1947 to July 1973. According to historicalrecords and information gained during interviews, IAAAP performed all of the operations relatedto the fabrication and installation of the explosive shells of shaped charges built around thefission core. IAAAP shipped the completed bombs to storage facilities off site.

Based on the reports ofpast operations at Line 1, the types of contaminants expected at Line 1include conventional explosives, materials unique to the assembly of atomic weapons, andchemicals used in the manufacturing of these products (see following paragraph). The followingare types of contaminants expected at Line 1 (see page xii Explosives Terms and Definitions foran explanation of terms):

• TNT and degradation products used in atomic and conventional munitions

• RDX

• HMX

• Lead (from lead azide, a shock-sensitive material used in primers)

• Barium (from baratol)

• Boron (from boracitol)

• Silver (from film processing)

• Depleted uranium (DU) (D-38 or U-238), a form of uranium used as an outer shell inmanufacturing some atomic bombs

• Trichloroethylene (TCE), a common chlorinated solvent used for degreasing and metalsurface cleaning

• Hexavalent chromium (used as an additive to control corrosion and deposits in the coolingtowers)

• Anthracene

• Vythene

Based on review of the historical operations information, including the aerial photographs anddrawings, possible chemical releases from Line 1 facilities include the following:

• Floor washings flushed out of doorways onto the ground

• Floor washings flushed out of buildings through floor drains and into nearby ditches, ponds,and surface waters .-,,--

• Occasional spills at material receiving docks

• Dust releases from open windows and doors that could settle on nearby property

Historical Data Review

TN&A conducted an extensive review of historical information and conducted several interviewsof former employees to develop an understanding that was sufficient to prepare the work plan forLine 1. The purpose of this effort was to identify past operations, housekeeping practices,equipment, and physical site features at Line 1 that warrant investigation by sampling andanalysis to determine the nature and extent of contamination caused by past releases. Because ofthe unusual physical size of Line 1 and the wide variety of different operations conducted overthe past 60 years of nearly continuous operations, the review of historical information was asubstantial effort.

TN&A used the following methods during our review of historical information:

• Searched the complete index of IAAAP site drawings to identify drawings relevant to Line 1.TN&A identified, obtained, and reviewed 1,059 drawings pertaining to the buildings,equipment, and utilities for Line 1. Of these, 229 drawings were particularly relevant to theobjectives of this work plan.

• Researched, obtained, cataloged, and reviewed almost 400 documents from AmericanOrdnance, the Burlington Public Library, and USACE Omaha District. TN&A providedsummaries of relevant documents in this work plan and created a document repository in ourOak Ridge office to facilitate document retrieval.

• Reviewed the findings of past environmental site investigations.

• Conducted interviews with 13 present and former IAAAP employees who had relevant workexperience and responsibilities for operations at Line 1.

• Researched, obtained, and reviewed historical aerial photographs covering the period of 1937(preconstruction) to 1998. The USACE Omaha District provided TN&A many of thesephotos. The photos were used to identify locations of physical drainage features, past landfeatures and the sequencing of building construction.

TN&A integrated and correlated the information obtained from all ofthese sources to developthe sampling approach and rationale detailed in this work plan.

1.0 INTRODUCTION

1.1 Purpose and Scope

The primary objective of this work plan is to gather additional information to better determinethe nature and extent of soil contamination in and around the Iowa Army Ammunition Plan(IAAAP's) Line 1. This is accomplished by (1) historically researching Line 1's productionactivities and chemical components used, (2) using this historical information to determinelocations where contaminants may have been released, (3) sampling these4ocations, and (4)analyzing the resulting data. The data acquired during this investigation will be incorporated intoremedial designs to clean up the site.

TN & Associates, Inc. (TN&A) performed a five-month search of the historic records databaseat IAAAP. During the course of this records search, TN&A personnel interviewed selectedformer, retired, and active IAAAP personnel and reviewed thousands ofmicrofiche records,engineering drawings, figures, maps, aerial photographs, and documents for applicability to theproject scope. Applicable records were assigned a TN&A record number, reviewed, scanned,copied for inclusion in this report, and/or placed in a file repository at the TN&A Oak Ridge,Tennessee, office. In addition, all of the drawings, maps, and figures applicable to thisassessment report have been scanned into electronic files so that they can be easily located andaccessed for review or inclusion in this report or future reports. A vast amount of comprehensiveinformation and data are presented in this document.

In addition to the historical research performed by TN&A, the analytical results from previousenvironmental investigations were utilized in developing the sampling plan for Line 1. Inparticular, results from the Remedial Investigation performed by JAYCOR (1996) were utilizedas field screening data in the selection of sampling locations for this work plan. (For example,JAYCOR sample locations that reported elevated levels of contamination are to be sampled in atriangulated pattern in order to delineate the extent of contamination.)

This work plan is associated with data gathering activities in conjunction with activities beingperformed by the U.S. Army Corps of Engineers (USACE) St. Louis Division under theFormerly Utilized Sites Remedial Action Program for former AEC operations at IAAAP.TN&A prepared this field sampling work plan as an addendum to the existing work plan andsampling and analysis plan (Harza 1999a). A copy of the Harza 1999a work plan and samplingand analysis plan will be kept on the site and used as a reference during the field samplingactivities at IAAAP. TN&A personnel will use the TN&A addendum as a site-specific workplan in conjunction with the existing work plan and sampling and analysis plan during thesupplemental site assessment for IAAAP's Line 1. This addendum details work to be conductedunder Contract No. DACA45-97-D-0015, Delivery Order No. 0016.

1.2 Work Plan Organization

This work plan provides an outline for site activities to be completed by TN&A during thissupplemental remedial investigation. The analytical results achieved through this plan will, inturn, assist in the identification and delineation of contamination present at Line I.

1.3 Site Location and History

1.3.1 Site Location

IAAAP occupies approximately 19,015 acres (30 square miles) in Middletown, Iowa (Figure 1).Within the IAAAP boundaries, in particular the northeast comer of the plant, lies the subject site,Line 1 (Figure 2). Line 1 is approximately 1 mile long, covers 173 acres, and encompasses over250 buildings and related facilities (Figures 3 and 4).

Line I Work Plan for Supplemental Rl.doc - 9/20/2001 Page 1-2Introduction


1.3.2 Summary of Line 1 History

This is a brief summary of the history of Line 1 in a chronological format. This' section containsreferences pointing to where more information can be found on background, such asconstruction, operations, and production in other sections of this report. Most informationprovided in this section applies to operations at Line 1 that resulted in or has potential forenvironmental contamination. This section has been written with information from historicalengineering drawings (Section 2.1), historical building records review (Section 2.2), historicalaerial photographs (Section 2.3), historical documents review (Section 2.4), and interviews withpast employees (Section 2.5).

Section 2.4 (historical documents review) contains additional background information on healthand protection surveys, documented explosions and accidents, MaCA investigations, historicalnewspaper articles, historic properties and archeological documents, environmental monitoringand beryllium investigation documentation.

1.3.2.1 Land Acquisition and Construction of Line 1

The main body of Line 1 buildings present today were constructed before September 1941. Priorto construction, the area of Line 1 was private fannland. In November 1940, an area ofapproximately 19,000 acres was acquired by the Office of the Quartermaster General for theconstruction of the Iowa Army Ammunition Plant, ofwhich 137 acres were used for the Line 1area.

Construction began in January 1941 by A. Guthrie and Construction Co., Inc., and Al JohnsonConstruction Co. Nearly all of the existing frame structures (private farmhouses, barns etc.) wereremoved. Operating buildings were built to be long lasting, with concrete foundations and floors,steel frames, and roof trusses, hollow tile walls, and asbestos roofing. [TN&A is aware that manystructures at Line 1 have asbestos insulation. TN&A is not scoped to evaluate asbestos as acontaminant of concern (COC) at this time.] Sewer tiles were constructed and connected to acentral sewage treatment plant located south of Line 1.

Where large quantities of explosives were to be loaded, remote controls were used behind strongbarricades. There were many hand-operated devices for assembling inert or non-hazardous parts.Automated loading and assembling machinery were installed only where necessary, some oftheequipment was semiautomatic for expediency. The workrooms were well lighted and ventilated.

Construction of Line 1 was completed in September 1941 and operations began immediatelythereafter.

For detail on the construction of Line 1 see the following:

• Section 2.1 for summary of selected early engineering drawings

• Section 2.2 for buildings summary (date constructed, square feet, use, etc.)

• Section 2.3 for a review of aerial photographs taken before and during Line 1 construction(August 1937 and July 1941)

• Appendix K for selected engineering drawings

• Appendix 0 for aerial photographs taken before and during construction

1.3.2.2 Army Production Begins

Loading operations contracted by the Anny to Day & Zimmennan began on Line 1 in September1941. Materials for ammunition production were shipped to Line 1 by train. These materialswere then housed in storage buildings. These materials were then conveyed from the storagebuildings to the melt buildings.

Shells produced at Line 1 during this time contained a mixture ofTNT and ammonium nitrate(amatol) explosive. The mixture was prepared by melting TNT and incorporating ammoniumnitrate with it long enough to ensure that each grain ofammonium nitrate..was thoroughly coatedwith TNT. During the pouring process a small amount ofTNT tended to crystallize on top of theoutside ofthe shell. This excess TNT was removed and collected on the floors. To preventaccumulation, the floors were steam-cleaned daily. The water from these cleanings was washedoutside the doorways into drainage ditches.

Melt Buildings 1-05-01 and 1-05-02 were reportedly the primary source of explosivecontamination during this time period. Documented infonnation on the disposal practices during1941-1947 is limited. However, based on interviews with employees who worked at Line 1during this time period, the network of drainage ways outside of almost every building was mostlikely used to convey wastes to Brush Creek (see Section 2.5 Interviews).

Production of ammunition was tenninated on August ·14, 1945. Operations after that dateconsisted only of completing work in process and renovating rejected ammunition.

Operation by the contractor tenninated in January 1946. The Government assumed the operationoflong-tenn storage, surveillance, demilitarization, and reconditioning activities.

1.3.2.3 Atomic Energy Commission Operations (1947-1975)

AEC operations of Line 1 brought construction of new buildings and facilities, weapons andmaterials, and new potential for environmental contamination.

1.3.2.3.1 AEC Operations (1947-1954)

In 1947, the AEC took over operations of the Line 1 facilities. In the same year, AEC contractedBlack & Veatch Consultants and Engineers to design the facilities needed in nuclear weaponproduction. During this construction, many of the buildings were renovated and retooled. Thisconstruction represents the first phase in the changes implemented by AEC during theiroccupation of Line 1. Notable changes were made to Buildings 1-04, 1-03, and 1-10.Building 1-08-2 was removed and replaced by Building 1-60 (barium nitrate preparation).

The first item of production after AEC took over operations at Line 1 was baratol and cyclotolcastings. The core buildings used in baratol production were Buildings 1-60 (barium nitratepreparation), 1-04 (Baratol Lab), 1-03 (sample casting preparation and crusher building),1-10 (Baratol Machining Bay), 1-05-1 and 1-05-2 (Melting and Casting). Other support buildingsfor this process were 1-06-01, 1-06-02, and 1-08-01 (TNT Storage and Preparation Buildings);1-50 (TNT inspection and Transfer) and 1-71,1-72,1-74,1-75, and 1-76 (ExplosiveComponents Rest Houses). Also, Building 1-73 was used as an X-ray Building. This buildingwas used to take X-rays of completed components to find flaws and to collect data needed tomake improvements. Building 1-12 contained X-ray machines for employee training and forbackup use. See Figure 4 for building locations.

Baratol and boracitol were utilized as thennonuclear primaries, whereby multi-stage nuclearweapons require a first stage fission bomb primary or trigger. Baratol is a barium-derivedcomponent that makes up what is known as the "lens". This high explosive surrounds the tamperand core of a trigger. The barium trigger was found to work poorly because barium's highmolecular weight dampened the energy dispersion. Later triggers were boron based (boracitol)so the thermal radiation emitted by the core was able to completely ionize the explosiv layer,allowing the energy to escape more readily.

After many practice runs, baratol casting production started on November 2, 1948. In January1950, ortho and para nitrotoluene were introduced as an outer componeritcrack preventative.The crack preventatives were introduced because castings would sometimes crack during roomtemperature changes. The crack preventatives were added during the melting process.

In the summer of 1951, construction of new processing facilities began. The addition of the newfacilities was done primarily because two different nuclear weapon models needed to beproduced at the same time. The current facilities were not adequate to do this. This representsthe second phase of construction made be AEC operations at Line 1. Most of this phase ofconstruction was not completed until 1952 or later.

A new X-ray Building was built (1-100) to replace the smaller inadequate X-ray Building 1-73.X-ray Building 1-100 contained two 1,000,000-volt (v) X-ray machines. The building alsocontained four machining bays to complete explosive machining operations required prior toX-ray. Contaminated water from the machining operations flowed through aluminum-linedgutters to the Filter Building or Clarifier 1-70 where solids were removed and then dischargedinto Brush Creek.

An additional Component Rest House was built containing 8 bays (1-07), a Machining Buildingof22 bays (1-40), and an Assembly and Shipping Building of 12 operating bays (1-61).Additional machining bays (6 each) were converted in areas of Buildings 1-10 and 1-12.

Contaminated waste from baratol production was collected in clarifiers and the heavy particulatematter collected and burned northeast of Line 1 in the West Burn Pad Area. The effluent fromthe clarifiers was discharged through a system of ditches into an impounding reservoir. Thisreservoir was dumped during periods of heavy rain to dilute the effluent safely and to preventundue contamination of down stream water.

In 1953, anthracene was introduced as an anti-cracking agent in Composition B melts. The levelsof anthracene added to the melts were not listed in this document. Also, in May 1953, fly ashwas added for the first time to the TNT effluent entering into Brush Creek. The fly ash wasadded to remove dissolved TNT from the waste water.

In the summer of 1954 reduced schedules caused many buildings to go into layaway status. TwoMachining Buildings (1-10 and 1-12), one Melt Building (1-05-1), three Rest Houses (1-74,1-75, and 1-76), and a Filter House (1-70) were some of the buildings put into layaway statusduring this time.

In October 1954, use ofa new industrial solvent, Vythene C, was used instead ofTCE andacetone for cleaning purposes. The gauge maintenance shop located in Building 1-01 was one ofthe primary users of these cleaning solvents.

1.3.2.3.2 AEC Operations (1954-1975)

Documentation during this period of ABC's history is limited due to the secretive nature of theiroperations causing many documents to be classified.

However, ABC continued explosive machining operations in the production of explosive castsfor nuclear weapons until pressing of plastic explosives into molds replaced them. A plasticslaboratory was established in Building 1-60 in 1962. Also in 1962, the effluent waste systemwas upgraded to collect waste at its source and transfer it along piping systems to an effectivetreatment system. Installation of cooling towers was started in 1962. ~~

A beryllium investigation at Line 1 took place from 1970 until 1973. Historical documentssuggest that swipe samples taken near sanding and case areas reported relatively high levels ofberyllium. The contamination is suggested to originate from beryllium dust on incomingcomponent parts that were not adequately cleaned prior to shipment. For information on thisinvestigation, see Section 2.4.2.2.

A MaCA investigation started in 1971. For information on this investigation, seeSection 2.4.2.4.

1.3.2.3.3 Army Operations (1975-Present)

In 1975, AEC turned over operations of Line 1 to the Army. Army operations began with155mm artillery ammunition production. The production of 155 millimeter (mm) rounds wasmoved to Line 1 from Line 3.

In 1977 Line 1 acquired the ability to produce XM53E2 grenades. Also tube Launched OpticallyTracked Wire-guided (TOW) and Dragon Warheads were being produced in 1977. A new X-rayunit was installed in Building 1-100 to radiograph HAWK warheads.

During the years 1978 through 1988 munitions production was steady. Weapons producedinclude TOW, HAWK, Dragon, VIPER, Chaparral, Stinger, Hellfire, Copperhead, Gator, Stormand XM815 warheads. Waste releases were regulated and controlled during this time period.

In an interview conducted on June 12,2000, it was mentioned that after Desert Storm, Building1-85-2 was used by the Army to pull uranium rods out of 120mm artillery shells. A drawingfrom 1995, entitled "Propellant Dump Fume Ventillation for 105mm & 120mm DU Demil,"illustrates a DU Demil bay in Building 1-85-2 as well. As these two sources indicate, the Armyhas performed demil operations ofDU since 1975; however, no manufacturing ofDU has beenconducted by the Army according to historical research.

For more information on Army operations from 1975 to present, see Section 2.4.1, HistoricalReports.

The narrative above on Line 1 history only covers the background information. More detailedinformation is provided below in Sections 2.1,2.2,2.3,2.4, and 2.5.

1.4 Site and Regional Setting

1.4.1 Climate, Topography, and Surface Drainage

1.4.1.1 Climate

The area has a mean temperature of 11 DC. The highest temperature ever recorded was 43.9°Cand the coldest was -33°C.

The average annual precipitation in the area is 103.2 centimeters (em). The rainfall is usually- . ~

well distributed throughout the year and provides ample water for abundant plant growth and thenumerous lakes and ponds. The extremes in yearly precipitation range from a high of 122.4 emrecorded in 1947 to a low of65.5 em recorded in 1963.

IAAAP is located in a moderate tornado frequency area, as determined by the U.S. WeatherService. According to a Department of Commerce study, the nearby area ofBurlington, Iowa,experienced a total of23 tornadoes over a 12-year period, averaging 1.9 tornadoes per year. TheBurlington area is considered to be in an area relatively free from earthquake activity(Installation Assessment ofIAAAP, USACE 1980).

1.4.1.2 Topography and Surface Drainage

The topography within IAAAP varies from a flat northern tier to gently undulating terrain withsteep slopes forming drainage ways in the southern portion of the installation. The central sectoris characterized by flat to rolling terrain dissected by shallow drainage ways. The elevationdifference within the installation is approximately 54.9 meters (m), with the average elevationapproximately 182.9 m above mean sea level. Three creeks and their tributaries control thesurface drainage. Long Creek drains the western part of the installation, flows into Mathes Lake,and leaves the installation along the southern boundary. Long Creek joins the Skunk River justsouth of the installation and flows 12.9 kilometers (km) to the Mississippi River. Brush andSpring Creeks drain the central and eastern parts, respectively, ofthe installation. These creeksexit along the southeastern boundary and then flow in a southeasterly direction for approximately6.4 km before emptying into the Mississippi River (Installation Assessment ofIAAAP, USACE1980). .

Line 1 topography is primarily flat with an average elevation of approximately 700 feet abovemean sea level. Several sloped areas and storm water drainage ditches convey storm water runofffrom the site to storm water outfall 001. The storm water eventually discharges to Brush Creek.Brush Creek exits along the southeastern boundary of the site and then flows in a southeasterlydirection for approximately 6.44 km before entering the Mississippi River.

Five watercourses drain IAAAP (Fig. 2). Little Flint Creek drains a small area in the north of thesite. The rest of the installation is drained by, west to east, the Skunk River, Long Creek, BrushCreek, and Spring Creek. Long Creek is a tributary of the Skunk River, which flows to theMississippi River. Brush and Spring Creeks are tributaries of the Mississippi River (Harza, April1999).

1.4.1.3 Vegetation on Site

Vegetation noted during the site walk through consisted ofgrasses, trees, and other ornamentalflora planted within landscaped areas at various locations on the site. No areas of distressed or

Line 1 Work Plan for Supplemental RI.doc - 9/20/2001 Page 1-7Introduction


discolored vegetation, which might be attributable to a discharge of environmental contaminants,were noted.

1.4.2 Geology

1.4.2.1 Regional Geology

The subsurface geology is described from the boring log of Water Well 4, which was drilled to adepth of 589 m in the northern part of the installation (Installation Assessment ofIAAAP,USACE 1980). The unconsolidated material consists oL41.8 m of clay;J1l.e percentage of sand,silt, or gravel was not reported. Underlying the clay is 59.1 m ofKeokuk Limestone of theOsage Series, Mississippi System, and is characterized as gray to buff interbedded limestone andchert. The sequence of formations and their thickness beneath the Keokuk Limestone wereidentified as:

• Kinderhook (Mapel Mill) Shale for 51.2 m

• Cedar Valley Limestone for 52.1 m

• Wapsipinican Shale for 8.5 m

• Maquokota and Galena Limestone for 65.5 m

• Glenwood Sandstone for 2.8 m

• Unnamed shale for 11.3 m

• St. Peter Sandstone for 43 m

• An unnamed 164.0-m zone ofcherty, dolomitic limestone. Within this limestone are a 0.9-mseam of shale, a 0.9-m seam of sandstone, and a 1.2-m seam of shale.

• Jordan Sandstone of the Cambrian System for 45.7 m.

• Unnamed limestone was encountered under the Jordan Sandstone at the bottom of the well.

The bedrock underlying IAAAP consists of a sequence of limestones interbedded with varyingthicknesses of shales and sandstones. The uppermost bedrock unit is composed ofchertylimestones interstratified with minor amounts of shale.

1.4.2.2 Site Geology

IAAAP is located in the Dissected Till Plain section of the Central Lowland Province of theSouthern Iowa Drift Plain Region. The site is underlain by a sequence of unconsolidateddeposits ofPleistocene age overlying sedimentary bedrock units. The glacial tills consistprimarily of silty clay and clayey silt with thin sand seams and lenses and are assigned to theKellersville Till Member (Illinoisan Age) of the Glasford Formation of southeastern Iowa. Thetills extend to depths in excess of 100 ft in portions of the northern half ofIAAAP but are thin orabsent locally in deeper stream valleys in the south, around Mathes Lake, and in the northeast(Harza, April 1999).

The bedrock underlying IAAAP consists of a sequence of limestones interbedded with varyingthicknesses of shales and sandstones, ranging in age from Cambrian to Mississippian. The



uppermost bedrock unit beneath the site is associated with the Mississippian Osage Series ofsoutheastern Iowa, composed predominantly of cherty limestones interstratified with minoramounts of shale. The Osage Series is divided into three members: the Warsaw Formation,Keokuk Limestone, and Burlington Limestone. The Warsaw Formation consists primarily ofblue-gray calcareous shales, fragmental, fossiliferous, dolomitic limestone, and calcarenites(Harza, April 1999).

The geology specific to Line I is essentially the same as that of the IAAAP installation.Additional information regarding site geology is presented in Chapter 5 ofthe Work Plan andSampling and Analysis Plan, Groundwater Investigation; Off-Site Growrtfwater Investigation(OU3), Iowa Army Ammunition Plant, Middletown, Iowa (Harza 1999a).

1.4.3 Hydrogeology

1.4.3.1 Regional Hydrogeology

In Des Moines County, Iowa, there are four principal aquifers: the glacial drift aquifer and thethree bedrock aquifers of the Mississippian, Devonian, and Cambro-Ordovician units. Theuppermost aquifer is a discontinuous surficial aquifer composed of unconsolidated loess andglacial till, with thin fluvial deposits of Pleistocene age in the streambeds. These occupy theuplapd till terrace and are predominantly clayey glacial tills that exhibit low hydraulicconductivities and yield only small quantities of groundwater to wells. Depth to groundwater inthe drift is generally less than 10 feet (t), and shallow groundwater flow parallels surfacetopography. Groundwater discharges to the more deeply incised surface drainages (e.g., streams)with additional discharge downward to deeper drift sections and the bedrock aquifer. However,low permeability in the drift restricts downward flow. Recharge to the drift aquifer is slow and isderived from infiltration of precipitation and possibly inflow from adjacent areas.

Information on hydrogeological conditions in the bedrock aquifer underlying the drift is sparse.Generally, groundwater in the limestones would be contained primarily within open beddingplanes and/or joints. Therefore, the occurrence and orientation of these features would controlgroundwater flow, in part. Also, it is common in the upper Midwest for much of thegroundwater in these bedrock units to be found in the more fractured and weathered uppersequence, just under the drift. Where this is the case, the lower drift and upper bedrock aquifersmay comprise a single hydraulic system. Sitewide, available groundwater levels suggest thatoverall flow direction in the bedrock is to the south and east toward the Skunk and MississippiRivers (Harza, April 1999).

1.4.3.2 Site Hydrogeology

Site hydrogeology was investigated during previous studies and is essentially the same as thehydrogeology of the entire installation. The hydrogeology at IAAAP, specifically depth togroundwater and groundwater flow patterns, is quite variable. Information regarding sitehydrogeology can be found in Chapter 5 of the Work Plan and Sampling and Analysis Plan,Groundwater Investigation, Off-Site Groundwater Investigation (OU3), Iowa Army AmmunitionPlant, Middletown, Iowa (Harza 1999a).



1.5 IAAAP Previous Environmental Investigations

Environmental investigations of the installation began in 1980 when an installation assessmentwas performed. The U.S. Environmental Protection Agency (EPA) Region 7 carried out anassessment of IAAAP in 1987 under the Resource Conservation and Recovery Act (RCRA) andthe Hazardous and Solid Waste Amendments and concluded that contaminant releases hadoccurred. A Federal Facility Agreement (FFA) was signed in 1988 between the EPA and theU.S. Army. EPA proposed IAAAP for the National Priorities List, and the site was added to thelist in 1990. In 1991 a Preliminary AssessmentlRemedial Investigation (PAIRI) was completed.Hased on the PA/SI, EPA and the Department of Defense entered into anmteragency agreementthat the site was to be cleaned up under the Comprehensive Environment Response,Compensation, and Liability Act (CERCLA). The agreement allows RCRA and CERCLAactivities at the site to be coordinated.

In 1992, remedial investigation (RI) and feasibility study activities began under the managementof the U.S. Army Environmental Center. Results of the RI were reported in the Revised DraftFinal Remedial InvestigationlRisk Assessment, Iowa Army Ammunition Plant, Middleton, Iowa(JAYCOR 1996). The RI included the results of the baseline risk assessment performed byICAIR Life Systems, Inc.

Beginning in 1994, USACE - Omaha was tasked with remedial design and remedial actionsbased on the U.S. Army Environmental Center RI data. In the fall of 1997, the U.S. ArmyEnvironmental Center was assigned to regulatory compliance, and USACE was tasked tocomplete the environmental remedial actions for soil and groundwater. USACE used HarzaEngineering Company to determine the fate and transport of explosives compounds from soil togroundwater. The Harza work was reported in the following deliverables:

• Basewide Groundwater Data Gap Work Plan (July 1996)

• Supplemental RI Basewide Groundwater Data Gaps (February 1997) (Harza 1997a). Thisincludes reproducible copies of the RI and historical aerial photographs.

• Ecological Risk Assessment Addendum, Feasibility Study, Proposed Plan and Record ofDecision for Basewide Groundwater (March 1997)

• Feasibility Study, Proposed Plan and Record ofDecision for the Treatment ofthe InterimROD for Operable Unit 1 Soils (December 1997)

• Supplemental Ecological Risk Assessment Addendum, Long-Term Monitoring for FYOO andthe Long-Term Monitoring Plan (June 1999) (Harza 1999b)

Based on the RI, a Record ofDecision (ROD) for the interim soils for Operable Unit (OU) 1 wassigned in September 1998. This ROD, which addresses Line 1, has been previously signed byEPA and USACE.

1.6 Contaminants of Concern

The contaminants of concern can be broken down into three groups: explosives, chemicals, andmetals. These explosives, chemicals, and metals are associated with past production anddemilitarization at IAAAP. A review of historical documents dealing with Line 1 operations and



interviews conducted with fonner and present employees revealed the following infonnationabout potential contaminants.

Explosives

Explosives of concern are boron-based explosives, barium-based explosives, RDX, HMX, TNT,PBX, Composition B, lead azide and mercury fulminate. The flow chart (Table 1.1) belowshows the overall movement of explosives during Line 1 LAP operations.

Chemicals

Chemicals of concern are boric acid, cyaneric acid, peniristol, barium sulfate, hexavalentchromium, MaCA, carbon tetrachloride, trichloroethylene, ammonium nitrate, ataphrene,acetone, nitro-cellulose, stearoxyacetic acid, ortho nitrotoluene, para nitrotoluene, anthracene,and boric acid.

Metals

Metals specifically mentioned in historical documents and interviews were beryllium, aberyllium/copper alloy, barium, silver (from film processing), and DU.tJeryllium buildinginterior contamination has been linked to sanding operations by AEC. Based on past berylliuminvestigations, beryllium releases were confined to the building interiors. Metals contaminationwas reported by the JAYCaR RI to be more widespread than explosives contamination at Line1. Metals of concern listed in the JAYCaR RI are lead, barium, arsenic, chromium, mercury,cadmium, selenium, and silver.

Metals contamination for the most part follows the same waste streams as explosivecontamination (see Sections 2.0 and 3.0). Some part of metals contamination can be linked toexplosives contamination. For example, barium metal contamination most likely can be linkedto the release of barium nitrate containing explosives into the environment.

Action Levels For Soils

Samples containing levels of constituents above the levels listed in Table 1.2 taken from theFinal Record of Decision, Soils au 1 report prepared by Harza Engineering Company in August1998 will be considered above action levels.

2.0 HISTORICAL SITE RESEARCH AND REVIEW

This section summarizes the historical infonnation which supports the field sampling plan(Appendix A) for Line 1 at IAAAP. This section contains individual reviews ofhistoricaldrawings (Section 2.1), building operations (Section 2.2), aerial photographs (Section 2.3),documents (Section 2.4) and interviews (Section 2.5) conducted with current and fonnerpersonnel.

2.1 Complete Historical Review of Drawings

During the research process 1,059 drawings pertaining to the buildings, equipment, sewagesystems, water systems, electrical schematics, process flow diagrams, and explosion debris fieldsfor Line 1 were obtained and reviewed. The drawings were obtained from American Ordnancearchives at lAAAP. TN&A has copies of all the drawings on file; the originals are located atIAAAP. A complete summary of each of the 1,059 drawings is included in Appendix J.Summaries of the 229 drawings detennined to be relevant are presented in Table 2.1. Drawingsthat included the following were of particular interest:

• Drawings that contained infonnation about a waste stream

• Process flow drawings included to provide an understanding of the process in a buildingand/or possible waste streams.

• Drawings showing the location of discharge points

• Drawings showing the location of contaminated water dumpsters

• Floor plans and drawings showing the layout of a building that are useful for detenniningpossible waste-streams and likely areas of contamination

• Plot plans showing the location of fiIter/bag houses and sumps

• Drawings showing the location ofcontaminated water troughs (open) and open ditches thatwere used in detennining areas of concern

Repetitive drawings were not included in the report. For example, several buildings hadarchitectural, electrical, HAVAC, and equipment layout floor plans. All relevant infonnationmay be obtained from the floor plan showing equipment layout. While the other titles may lookuseful, they would contain no additional infonnation needed that was not obtained from the onedrawing. Similarly, drawing may contain detailed infonnation of a component but not give abroad enough understanding to draw any conclusions for sampling rationale. Such drawingswere not included in this report.

2.2 Historical Review of Buildings

The buildings located at the Line 1 are listed in Table 2.2, along with the date of construction,size, and use of each building. The information was obtained from an "Inventory ofMilitaryReal Property" dated March 1999 and a "Complete Building List" dated February 5, 2001,supplied by American Ordnance. Included in the table is information on the availability ofscanned drawings associated with the buildings and the potential for waste streams.

I~ preparing Table 4, the following documents were rese~ched.

• Industrial Facilities Inventory, dated March 1944. It was compiled from existing records asof January 31, 1944. Prepared by the Corps of Engineers, Omaha. [190]

• Industrial Facilities Inventory, Addendum No.1, dated August 1, 1944. Prepared by theCorps of Engineers, Omaha. [188]

• Industrial Facilities Inventory, Addendum No.2, dated July 1, 1945. Prepared by the Corpsof Engineers, Omaha. [189]

• Real Property Record - Buildings and Structures, WD AGD Form 5-47. Entries on theseforms were dated April 3, 1946. These records were located in the Engineering/ DraftingSection ofAmerican Ordnance at IAAAP. [442]

• Inventory ofMilitary Real Property as ofMarch 29, 1999. This printout was provided toTN&A by the American Ordnance Real Property Administrator (Ms. Judi Morgan) atIAAAP. [439]

• Complete Building List dated February 5, 2001. This document was provided by theAmerican Ordnance Real Property Administrator (Ms. Judi Morgan) at IAAAP. [440]

In many cases, the title of the building/facility states what the building was used for. However,in some cases an explanation was requested and provided by American Ordnance. These Line Ibuildings are:

Building Number Building Description and Purpose

0-01 Inert Pour

Use: Storage and shops. Its electrical classification limited its usebecause it contained general purpose wiring.

1-18 Chemical Equipment and Material Facility. (This title was also used on1-19-1 thru 7 and 1-53.)

Use: Storage facility.

1-63 CellI. (This title was also used on 1-63-2 thru 7.)

Use: Used initially for weapons assembly. Presses were installed in thebuilding after the departure of AEC.

2.3 Historical Aerial Photographs Review

TN&A reviewed 81 aerial photographs dating from 1937 to 1998 to gain insight about land useand development at IAAAP. The photographs show land use and development at the site ofLine 1 prior to commencement of construction and up through the 1998.

The photographs were valuable for determining the drainage patterns at Line lover the years ofoperation. Through interviews with IAAAP personnel, it has been determined that thesedrainage-ways are a very likely source of contamination._Photographs \V~ also valuable inascertaining areas of soil disturbance, which may indicate likely areas of contamination. Thepresence or absence of new or existing structures was also noted.

The absence of aerial photos over a 15-year period leaves a significant data gap during the mostactive period ofproduction at Line 1. There are no aerial photographs available ofIAAAP from1942 to 1957. Aerial photographs were taken in 1951 but are classified and available undersecurity authorization only (Ref. 282, p. 6).

Harza Engineering Company obtained the aerial photographs from the National Archives inCollege Park, Maryland, and from the Aerial Photography Field Office of the Farm ServiceAgency in Salt Lake City, Utah. A copy of the 1998 photograph was obtained from USACEOmaha. Currently the photographs are located at the TN&A's Oak Ridge, Tennessee office.Each photographs reviewed has a unique TN&A number assigned to it, and the majority of thephotos have IAAAP archive numbers printed on them:

Melt conveyors and ramps have also been completed. Construction roads branchout in all directions. A construction road roughly parallels Brush Creek at Line 1 and crossed thecreek northwest of Building 1-13. Soil and plants in and around Line 1 have been disturbedsince the 1937 photographs. Soil has been disturbed on the banks of Brush Creek at the northend of Line 1. A small amount of timber has been removed from Brush Creek. A small grove oftrees stands to the west of Building 1-05-1 between the melt conveyors.

2.4 Historical Document Review

The categorized document summaries below represent the relevant parts of almost400 documents obtained from American Ordinance, USACE-Omaha, and the Burlington PublicLibrary by TN&A. Per USACE-Omaha direction, an attempt was made to obtain everydocument on file related to the Line 1 subject area. For a complete list of historical documentsreviewed during TN&A research of Line 1, see Section 4.0.

~he documents addressing Line 1 or AEC operations (wbich took place_1m Line 1) werethoroughly reviewed and are summarized in the following subsections: Historical Documentsand Historical Environmental Investigation Documents. The historical documents, reviewedfrom the microfilm files at the Burlington Public Library (obtained by the National Archives andRecords Administration in Kansas City, Missouri), showed great variance in content and depth.Documents that have no information pertinent to Line 1 are included to clarify that theinformation in the document is insignificant to the Line 1 subject area.

This section contains information on historical chemical and explosive waste generation,radiological investigation documentation, health and protection surveys, sump removaldocumentation, documented explosions and accidents, MOCA investigations, historicalnewspaper articles, historic properties and archeological documents, environmental monitoring,and 'beryllium investigation documentation.

2.4.1 Historical Reports

This subsection is further divided into Plant History and Laboratory Operations. The mostimportant documents summarized below are under reference numbers 184, 187, 146, 186, 168through 171, 160, 176, 289 through 292, and 441. These documents are significant because theydescribe in detail the various waste disposal methods, building uses and operations, anddecontamination methods and locations in the Line 1 facility. TN&A used this information, todelineate probable contamination present at the site and to determine appropriate samplinglocations.

Operations on Line 1 ceased on August 18, 1945 (V-J Day). Expansion on line completed. OnAugust 27,1945, Iowa Ordnance Plant (lOP), as IAAAP was formerly named, was designated a"nucleus plant." Instead of being completely decontaminated, it was merely to be prepared forextended storage. All inert buildings were either washed down with cold water or cleaned bythoroughly wiping or brushing them out.

Exp'losive buildings were washed down with hot water and steam where necessary. In someinstances, appropriate solvents were used to remove explosives. No additional information isprovided in this reference as to what solvents were used and how they were disposed of on Line1.

All piping, duct work and machinery that were likely to be contaminated with explosives werethoroughly washed with hot water and steam and, where necessary, appropriate solvents. Thedegree of decontamination was indicated on each piece of piping, duct work or equipment by oneor three "X's" in accordance with paragraph 4 of War Department Supply Bulletin SB 5-52.

All steam and water service lines, as well as electric services lines, were disconnected and placedin a safe condition for extended disuse.

Grounds around explosive buildings for a distance of approximately 50 feet were tested and,where necessary, the earth was removed to such a depth as to remove all explosives. However,five areas are shown on Drawings 6696 and 6697 (Schedule VI, pages 143 and 144) from whichcontaminated earth was not removed. (Note: These drawings could not be located.) These weremore or less isolated areas and were fenced offand marked as being contaminated in accordancewith subparagraph d, paragraph 4, War Department Supply Bulletin 5-52.

All explosive sumps were cleaned with hot water and steam and, where necessary, neutralizingsolutions.

All machinery and equipment likely to deteriorate from rust or corrosion, after cleaning anddecontamination, were coated with rust preventative in accordance with paragraph 329, 18b ofSection III of the Field Director's Manual.

Certain items of equipment, such as electric motors and other machines as well as switchboardsand similar controls, were covered with waterproofpaper to preserve them intact.



All wooden or other equipment of combustible material, which could not be adequately cleanedwith hot water, steam or desensitizing solutions, was destroyed by burning.

Upon completion of this work in the various parts of the Plant, each part was individuallyinspected by representatives of the Contractor and the Ordnance Department for acceptance.

During the early summer of 1947, Silas Mason Company entered into a contract with theOrdnance Department to assist in the design and engineering, to perform the construction, and tooperate a facility for supplying the AEC with explosive components for a nuclear weapon.

Black & Veatch, Consultants and Engineers of Kansas City, Missouri, made the original reportto the AEC, and the firm was engaged as Architect-Engineer. Construction was under thesupervision of the Corps ofEngineers, Missouri Division ofthe Omaha District.

A Dr. RH. Sage at the California Institute of Technology (CIT) and the Naval Ordnance TestStation (NOTS) was chosen as Process Consultant.

The climate at IAAAP is very different from the climate at either NOTS or Los Alamos. Wintertemperatures at IAAAP are as much as 20 degrees colder than temperatures at NOTS and 10degrees colder than those at Los Alamos. This somewhat extreme variation in weatherconditions was considered cause for much concern. As a result, air conditioning was thoughtnecessary at strategic operating points so as to more nearly duplicate the weather at NOTS andthereby assure acceptable product without the introduction ofprocess unknowns.

To save time and construction costs, the floors in the buildings within Line 1 were left as theywere and cleaned with mops or squeegees instead ofby the elaborate gutter and sluicing systemsused at NOTS. For the processes that generate either fumes or dust, it was decided that localventilation systems would be used instead of the general ventilation principle used at NOTS, andall such fumes and dust would be passed through approved "wet" type collectors.



Since it was necessary (for AEC) to test-fire standard samples of the product for quality controland ballistic data, and since no nearby range or proving ground was available, it was decided thata firing area would be provided within the IAAAP area to decrease the time and expensenecessary to obtain pertinent information prior to shipment of the product. In this context, theproximity of villages, fann houses and the like was cause for concern over claims and damagesresulting from the blasts. Therefore, it was decided that preliminary testing for blast effectswould be carried out prior to the final selection of a site for test firing.

Four bays in Building 1-05-1 were designed for Baratols. The circulating system in these bays,together with essential utilities and equipment, were given first priority.-An expeditor wasassigned the duties ofeither borrowing or acquiring enough Baratol molds to start on schedule.

The original plan for Building 1-01 was that it be used for administrative offices. However, itwas decided that, for safety considerations and since office space was available in the mainadministration building at IAAAP, Building 1-01 would be used exclusively for shops.Administrative offices were then located in the main lAAAP administration building(Building 100-101) and the line offices in Building 1-04.

Box manufacturing was completed in the carpenter shop, which was equipped with conventionalsawdust and shaving removal and collecting equipment. Box painting was provided with a watercurtain collector so as to preclude the escape of vapors or fumes that might enter the airconditioning system ofan explosive building. Approved hoods and exhaust systems wereprovided at welding and blacksmith shops. Air conditioning was installed in the tool and gageshop to preclude condensation ofmoisture and subsequent corrosion of tools and gages.

It was necessary that the control laboratory in Building 1-60 be essentially complete so thatpreparation of barium nitrate could be properly processed. The central control laboratory inBuilding 1-04 was complete only so far as necessary to support Baratol production. The samplepreparation and crusher Building 1-03, where explosive cast samples were crushed, wasactivated to include two cabinet units and two hydraulic jacks. These jacks initially wereoperated manually since some ofthe basic equipment required long delivery times.

To supplement laboratory services, a small solvent storage building was needed, which waslocated and erected just east of Building 1-04. A large underground gas installation for Bunsenburner service was also designed; however, installation was cancelled in favor of a bottled gassystem serviced by a local distributor.

Since the first item ofproduction was Baratol, emphasis was placed on essential items ofequipment necessary for Baratol material preparation. The barium nitrate preparation buildingwas a new building, arrangement of which was specified by NOTS and designed by Black &Veatch. Since dry barium nitrate was required (20 percent relative humidity), such features asspecial vapor barriers and dehumidification equipment were included in the building design.This new building was constructed on the site from which Building 1-08-2 was removed and wasdesignated Building 1-60

TNT required in Baratol preparation was temporarily stored in Building 1-06-1 and wasinspected in Building 1-50, where a few additional facilities were required. Nitro-cellulose andstearoxyacetic acid were temporarily stored in Building 1-06-1 and were tested inBuilding 1-04's Laboratory.



For material handling, a trolley conveyor was available within the lines at IAAAP.

The equipment with modified pendant was installed to connect material preparation facilities,i.e., Buildings 1-06-1, 1-06-2, 1-08-1, and 1-60, with the transfer building 1-50. FromBuilding 1-50 similar conveyors were installed to supply the raw materials to the Melt Buildings.The Melt Buildings were designated as Buildings 1-05-1 and 1-05-2, and the Equipment Roomsas 1-05-1E and 1-05-2E. Machining bays designed for Baratol operations were located inBuilding I-tO.

Gammagraph and radiograph facilities were required for-inspection opel'~ons and foraccumulation of data from which adjustments could be made were necessary in productionprocedures. The shape of the building, eventually designed at Building 1-73, was underdiscussion from the beginning. Delivery ofneeded items of equipment caused a delay in thecompletion of this facility. X-ray facilities were not required until the second phase ofproduction, so a minimum of construction in the form of shielding, utilities, and temporarycontrols were provided for one X-ray bay. This equipment was located in Building 1-12 to beused in an emergency and to train personnel.

Rest houses designed as Buildings 1-71, 1-72, 1-74, 1-75 and 1-76 were erected to the west ofthe main Buildings I-tO and 1-12. These were to serve as flow regulators so as to smooth theproduction line operation and at the same time to allow for the curing ofthe various explosivecomponents for a sufficient period of time to assure that thermal stresses were relieved.

Preliminary studies indicated that the central water supply and treatment plant was entirelyadequate, providing that water recovery equipment, such as cooling towers, would be installedwhen water consumption was high. Cooling towers were located at Buildings 1-10, 1-12 and1-60 to provide cool water for air conditioning utilities, and at 1-05-1 and 1-05-2 a doublecooling tower was installed to provide the necessary cool water for process operation. At othersmaller air conditioning installations, such as Buildings 1-04 and 1-01, evaporative coolers wereused.

A preliminary survey of Line 1 and surrounding facilities indicated that the existing installedsanitary and storm sewage disposal facilities were entirely adequate. No system or equipment,however, was in evidence that would provide a satisfactory means to dispose ofcontaminatedwaste other than burning; large quantities ofthe waste material would be wet from machiningcoolant, kettle washdown, and the like. A study was made of the necessary facilities to safelydispose ofthis material. The Architect-Engineer proposed clarifiers to sludge out heavy particlesof the waste and dispose of them by tanks trucked to the burning ground. The diluted effluentfrom the clarifiers was discharged through a system of ditches into an impounding reservoir,which retained the contaminated materials. The reservoir was dumped during periods ofheavyrain, and thus the effluent was diluted safely to prevent undue contamination of down streamwater.

Because of the late delivery ofmuch equipment, it was necessary to make a number oftemporary installations.

• Building 1-01. All the shops were in use on both construction and operation jobs.

• Building 1-04. The 1-04 laboratory was partially complete and was used for the necessarycontrol analyses. The remainder of the building was under construction.



• Building 1-05-1. This building was divided by a barricade. The north half was used forproduction while construction continued in the south half. The NOTS-type 500-poundkettles had not been delivered, and temporary "candy" kettles were used for melting. Thesekettles had no provision for evacuation of the melt. The transport kettles had not beenreceived either, and it was, therefore, necessary to pour the melt by using rubber buckets.

• Buildings 1-06-1 and 1-06-2. These buildings were used for the line storage of rawmaterials.

•- Building 1-10. This building was complete to the point where it couk44Je utilized for Baratolmachining, repair, and inspection on one shift. Machining coolant water equipment was notcomplete, so a domestic-type water heater was temporarily installed to furnish temperedcoolant water. Construction continued on the other shifts.

• Building 1-50. This building was used for explosive raw material inspection and conveyorrouting.

• Building 1-60. The operation of this building was essential to any production ofBaratolcastings, and at least one unit of each piece of processing equipment was required in thisoperation. The equipment was wired with temporary wiring, and an ammonium nitratecooler was used in place of the Stokes Dryer, which had not been received. The dehumidifier~as not in operation. This building was operated on two shifts while construction continuedon the third shift.

During the last week of October 1948, melting and casting operations were transferred toBuilding 1-05-1, and on November 2, 1948, production of outer components was started. Themove to the second melt building (1-05-2) and the use of vacuum kettles reduced theradiographic Baratol rejects to a point where efforts could be concentrated on ballisticperformance.

In January 1950, additives ortho and para nitrotoluene were introduced as a crack preventativemeasure in Outer and Inner Components. Cracks, which previously had been reduced by usingKimpac around molds and castings to buffer the effect ofchanges in room temperatures on thecooling rate, were appearing in Outer Components. A mixture of ortho and para nitrotolueneadded to the Composition B melts essentially eliminated the cracks.

During the summer of 1950, it was decided to double the capacity ofthe plant. Constructionplans for revision of Line 1 facilities had been initiated during the summer and fall of 1950 andby January 1951, production schedules were increased to complete the MK 4 Program as soon aspossible so that new construction could begin by the summer of 1951.

On September 18, 1950, a proposal by Silas Mason Company was submitted for the addition offour new processing buildings to the existing facilities, with interconnecting ramps andmodification of other existing facilities to provide the required capacity. The design of thesefacilities involved a concept long advocated by Silas Mason Company. The new buildings wereto be built with their roofs at ground level.

New specifications for taking X-rays of completed munitions was cause for a new X-RayBuilding to be constructed. This was numbered Building 1-100 and constructed in the linebetween the casting building and the machine buildings.



The existing Plant did not provide a sufficient number oftemperature conditioning bays,machining bays and assembly bays. Since it was necessary to produce two different models ofweapons at the same time, it was planned to make additions so that two production lines mightbe operated within the existing manufacturing area. This called for the addition of a rest houseof 8 bays (Building 1-07), a machining building of 22 bays (Building 1-40), and an assemblybuilding of 12 operating bays (Building 1-61). In addition to these, six bays in the existingBuilding 1-10 and Building 1-12 were converted to machining bays. The process flow for thetwo models divided at the new X-ray building: the components for one Mark (weapon system)going down the old line to Buildings 1-10, 1-12 and 1-1 J by way of a ne»Uamp, andcomponents for the other going through the new buildings.

The cafeteria and change house facilities that existed did not provide services for the number ofpeople expected. To solve this problem, three change house-cafeterias were proposed. One ofthese was to be in an enlarged Building 1-137-2, displacing the garage facilities located in thatbuilding. This would serve personnel working in Buildings 1-10, 1-12, and 1-13 and otherlocations in the south end of the line. The old change house, Building 1-137-1, was within thequality distance of the location for Building 1-07. Therefore, a new Building 1-137-4 was builtto serve the preparation area and Buildings 1-05-1, 1-05-2, 1-100, 1-40, and 1-61. To providegarage service for the Division "B" operations, a new structure, Building 1-129, was planned. Itwould contain four service bays, two containing hoists sized for both cars and trucks. The usualfilling stations and garage facilities were provided. (Note: There is no indication in otherhistorical documents or drawings that there may have been underground storage tanks for thisservice/filling station.)

Railway service was provided to Building 1-61. The aboveground portions of Building 1-61 and1-100 were barricaded by earthen embankments. In the case of Building 1-100, this requiredenlarging the barricade to the north ofBuilding 1-10 and placing a new one to the north ofBuilding 1-100. Building 1-61 was barricaded to the north and west. Building 1-07 wasdesignated as a Rest House used for temperature conditioning ofhigh explosive components.Attached to Building 1-07 is an equipment room with air conditioning equipment consisting offilters, preheat coils, cooling coils, humidifier, fan, eight zone reheat coils, and necessarycontrols.

Building 1-40 was designed with a new concept in explosive processing. It was compact forefficient operations and still provided necessary bay-to-bay safety. It was designed and built as amachining building, which consisted of 22 operating bays along a central corridor, and"u"-shaped around an equipment room, Building 1-40E. Building 1-61 was designed as anassembly and shipping building. In Building 1-61, sewage is pumped to the sanitary sewer andground water drainage is pumped to open ditches by duplex pumps. Condensate from theheating facilities is returned to the boiler house.

Because of the quantity distance from Buildings 1-05-1 and 1-10 and the locations ofRamps 1-82-8, 1-82-9 and 1-82-64, Building 1-100's size was limited. Its primary purpose wasto house two, one million-volt X-ray machines. Its secondary purpose was to provide fourmachining bays to complete machining operations required prior to X-ray. Contaminated waterfrom the machining operation flowed through aluminum-lined gutters to the filter building(Building 1-70) where the solids were removed as described earlier.

There are connecting ramps between various buildings on Line I. Buildings 1-07 and 1-100 areconnected by the underground Ramp 1-82-67. It can be reached from Building 1-100 either bymeans of an elevator or stairs. The ramp passes under the plant water main at approximately themid-point ofthe ramp. Ramp 1-82-68 connects Buildings 1-07 and Building 1-40. It isunderground with approximately 4 feet of groundcover. Buildings 1-40 and 1-61 are connectedby Ramp 1-82-69. Ramps were built from each change house to connect with parts oftheoperating line to protect personnel from inclement weather after they had changed to protectiveclothing. These ramps were numbered as follows: from Building 1-137-2, Ramp 1-82-61 was toiQ.tersect with Ramp 1-82-55, Ramp 1-82-61 was extended to Building Id,.37-4; from Building 1137-5 to Building 1-01 Ramps 1-82-71 and 1-82-72 were built. Ramp 1-82-5IA was extended tointersect with Ramp 1-82-2 to move material to Building 1-13 by forklift trucks.

Buildings 1-10 and 1-12 were existing machining buildings. However, most of the bays wereoriginally designed for storage and temperature conditioning ofvarious components. Theproposed expansion required that additional machining bays be constructed in these buildings, so2 were constructed in Building 1-10 and 4 in Building 1-12, making a total of 16 machining baysin these 2 buildings.

During the summer months of 1953, cracks on the top curvature ofMK 6 and 7 inners andovercasts began to appear. This was corrected by adding a small quantity of anthracene to eachComposition "B" or Cyclotol melt. By the end of September, experimental and developmentalwork began on a new Slow Component using a boric acid-TNT slurry called a Boracitol. Thiscomponent was to be used in a new Cobra assembly.

Contaminated water disposal has been a foremost problem at IAAAP since initial production.Elaborate filtering systems have been installed throughout Line I. However, dissolved TNT inthe water cannot be removed by this method, and so extensive research has been conducted toestablish a procedure to remove the TNT from the streams. It was found that fly ash from thereservation power plants would decontaminate the water, if applied in portions of 100 pounds offly ash per 500 gallons ofwater. A temporary hopper was installed over the stream to dispensethe fly ash into the water. The fly ash treatment reduced the TNT content from 32 to 1 ppm.This procedure has been in effect since May 1953, and periodic tests ofthe water below the flyash hopper indicated that the TNT content is below I ppm.

Security requirements, as prescribed by the AEC, were relaxed on 21 May 1951. The securitycover was lifted, and the relation of the work to the AEC program was publicly announced.

31 July 1954 (Ref. 186)Project History of Line I Operations at the Iowa Ordnance Plant, 1 July - 31 December1954. Report was completed in April 1955. This report was formerly classified as "SecretRestricted Data" but was declassified on 10/30/00

Research and Development Engineering Section was established to investigate new andimproved methods for manufacturing explosives.

A report was prepared and distributed, Research and Development Report No. 6-54-3. Thereport covered the methods for the disposal of TNT-contaminated effluent water at thisinstallation. As discussed in earlier historical reports, it involved adding fly ash from theinstallation's power production plants to the contaminated effluent.

A project was established to conduct a systematic study to determine the effects ofphysical andchemical variables on product quality and establish limits for their control. Initial work has beenconcerned with a study of physical assembly factors, which affect detonation characteristics, andthe relative merits of using aluminum silicofluoride on test fire castings.

In the Chemistry Laboratory, methods for recovery of two solvents used extensively in thelaboratory have been perfected. The benefits derived from this amounts to $160 per week for theacetone recovered and $85 per week for the benzene recovered.

Reduced schedules, along with economy measures, permitted consolidation of operation intoone-halfof the production line. Layaway into a standby status was immediately started on thefollowing buildings:

• Building 1-137-2 (Cafeteria)

• Building 1-05-1 (Melt)

• Building 1-10 (Machining)

Line 1 Work Plan for Supplemental Rl.doc - 9120/2001 Page 2-55Historical Site Research and Review


• Building 1-12 (Machining)

• Building 1-70 (Filter House)

• Building 1-74 (Rest House)



.. Building FS-1 (Firing Site Administration) -.-

• Building FS-2 (Firing Site Shop)

• Building FS-5 (Firing Site Magazine)

• CB Yard (Storage Area).

The buildings and equipment were placed in first-class operating condition prior to theapplication of preservatives. All process equipment has been dismantled and decontaminatedand parts were replaced when necessary. During layaway, the photographic laboratory in FS-1was moved to the X-ray building (Building 1-100), the test fire preparation area was moved fromFS-5 to Building 1-71 (formerly a Rest House), and the electronics shop was moved from FS-2to Building 1-129. These consolidations permitted closing the Firing Site steam plant.

The MK 12 program was in process through the MC-181 assembly stage with Building 1-40processing the HE for both the MK 12 and Cobra programs. A total of 14 inspectors wereemployed in Buildings 1-40 and 1-61 for these operations.

During this reporting period, Production personnel assigned to layaway activitiesdecontaminated the floors, walls and equipment in Buildings 1-137-2, 1-05-1, 1-10 and 1-12.All remaining tooling was processed for storage outside of the line. Procedures were establishedto use Building 1-12 as a processing area, Building 1-05-1 was used for decontaminating itemsprior to processing, and Building 1-53 was used as a loading site for crated items to be placed inwarehouses.

The use ofa new industrial solvent, Vythene, was begun in October in Building 1-40. Thissolvent replaced trichloroethylene and acetone for cleaning purposes, especially at the gaugemaintenance shop. The low toxicity ofthis new solvent makes it ideal for use at this location.

Vythene is a trade name for Methyl Chloroform, or 1, 1, I-Trichloroethane. Methyl chloroform,or 1, 1, I-Trichloroethane, is a standard target on the compound list. According to the MaterialSafety Data Sheet (MSDS) on this chemical, 30 percent of the product is used as a solvent forhot degreasing ofmetals and 30 percent used for cold degreasing ofmetals. In addition, thischemical is less toxic than TCE and PCE.

Appropriations for converting Building 1-53 into a scrap recovery plant were approved, andconstruction to modify the building was begun on December 13, 1954.

In other actions involving Line 1 buildings, the Line 1 First Aid Station was closed on July 19,1954. On October 11, 1954, Building 1-71 was vacated by Production and turned over toInspection for FS Operations. On October 13, 1954, Building 1-53 was vacated by Production

and turned over to Engineering and construction. On October 27, 1954, Building 1-73 wasvacated by Production and turned over to Stores for lE-24 detonator storage.

In helping with reduced operations Plant-wide, Fire Station No.2 was closed and secured onAugust 16, 1954. The equipment was moved to the main garage area.

In another area, EPA and the U.S. Army Toxic and Hazardous Materials Agency (USATHMA)conducted surveys at IAAAP of soil that is subject to migration of explosives and other toxicsubstances, and areas in which water might be contaminated by such materials.

. January 1980 (Ref. 176) Installation Assessment oflowa Army Ammunition Plant, RecordEvaluation Report No. 127, Final, January 1980 (Draft September 1978), by Department ofthe Army, Office of the Project Manager for Chemical Demilitarization and InstallationRestoration, Aberdeen Proving Ground, Maryland 21010

Under the section titled: Purpose of the Assessment. (1) To search for, identify, and assessactual or potential toxic or hazardous chemical, biological, or radiological materials contaminantmigration at Iowa Army Ammunition Plant (IAAAP), Middletown, Iowa, resulting frommilitary/industrial operations conducted for the Department ofDefense. (2) To identify anyimmediate on-post conditions associated with chemical, biological or radiological materials, orload, assembly and pack (LAP) operation contaminants and unexploded ordnance (UXO) whichcould contribute to a contaminant migration problem.

Line I Work Plan for Supplemental RI.doc - 9120/2001 Page 2-65Historical Site Research and Review


Much research has been perfonned on Line 1. It its earlier days, it was used in the LAP ofshells, bombs, cartridge, missile warhead and other munitions. From 1947 to June 1975, Line 1was operated as the Burlington AEC Plant. On July 1, 1975, the plant was turned back over tothe U.S. Anny. Over the years, the plant has produced conventional munitions. During 1947thru mid-1975, it was involved in the final assembly ofnuclear weapons for the AEC. At notime was the IAAAP involved with any chemical or biological warfare weapons. At one time,two riot control agents (CN - Tear Gas, Chemical name: w-chloroacetophenone and CS- RiotControl Agent, Chemical name: ortho-chlorobenzyllene malononitrile) were stored in one ormore ofthe ammunition storage igloos on the site. ~~

From interviews, it was detennined that during the AEC period, Line 1 was the greatestgenerator ofexplosive waste and pink water due to the machining of explosives in the·'Monarch" lathes with water coolant in addition to nonnal washdown and reject steam out.

Personnel from EPA visited IAAAP on September 7,1977, to review the status of radioactivecontamination of the facility. A limited survey of the area showed gamma ray levels that rangedup to 10 times the background level. A sample of soil at the point of highest reading and a watersample from Long Creek, which drains the Firing Site area, were sent to the EPA Las VegasLaboratory for analyses. Results of the analyses were sent to lAAAP in a letter dated May 30,1978. The IAAAP personnel subsequently called the EPA for an evaluation of the results andwere told that there was ·'absolutely nothing to be concerned about."

In the early 1960s, an atomic bomb that had received minor damage in an airplane crash wasbrought to IAAAP for disposal. The bomb was disassembled; part of it went to the ExplosivesDisposal Area and the classified parts were sent off the installation for disposal. No radioactivecontamination resulted from this exercise.

Carcinogens and oncogens that have been used at IAAAP, prior to this report which was issuedin 1980, include asbestos, benzene, beryllium, chlorofonn, MaCA (methylene-bioorthochloroaniline), nitrosamines, o-toluene, zinc chromate and trichloroethylene.

The installation has generated a huge quantity of fly ash at a production rate of 1,452 metric tonsper month. This material lies on the west bank of Brush Creek south of the main sewagetreatment plant. Some of it was used in the past to remove TNT nitrobodies from Brush Creek.The fly ash was mixed with creek water in a hopper and then it was flushed into the creek whereit picked up TNT and settled out.

The most significant holding/settling ponds include the Line 1 settling pond (fonnedy active)used by AEC and the Line 800 Leaching Pond. A pond was created at Line 1 by damming upBrush Creek. Explosive wastes including TNT, Composition "B" cyclotol, PBX, barium, andother materials were discharged into this impoundment. Analyses of water samples takenimmediately below the dam in 1952 showed TNT concentrations as high as 114.6 ppm. The damwas later removed and the impounded area was cleaned out. The FS Area is the only site on theinstallation that has been used to destroy munitions containing radioactive material (depleteduranium-238) in addition to explosives. Conventional explosives handled there include PBX,TNT, Composition "B," cyclotol and tetryl.

There is no evidence of major spills of hazardous materials having occurred at lAAAP. Eachproduction area in general is considered to be contaminated with explosives peculiar to the area


Work Plan for Supplemental Remedial Investigationfor Line J (Including Historical Site Assessment) - IAAAP

as a result ofminor spills and/or dust. Dry spills and dusts were swept up for disposal at theExplosive Disposal Area.

Brush Creek flows along the southwest side of Line 1. Between 1949 and 1955, waste waterfrom Line I was discharged into Brush Creek to the extent that contamination was detecteddownstream. A concrete dam was constructed across Brush Creek to form a semiholding pond.This holding pond reduced concentrations of solids downstream, but the sediment began to buildup on the bottom. After the dam was removed, Brush Creek was flushed out by rainfall, but theflat area bordering the creek was heavily contaminated.

It has been documented that farm wells along Brush Creek have been contaminated byexplosives and associated wastes in the past. These wells were all considered to be shallowwells 12.9 to 15.240 meters deep. The contamination was attributed to IAAAP operations. TheArmy paid for putting activated charcoal filters on the farm wells and for recharging the filtersfor approximately 20 years. It is not known exactly how the wells were contaminated; however,two theories were presented at the time (1952-1953): (1) Contamination came from nearbyBrush Creek to the wells. (2) Contamination seeped into groundwater on IAAAP and eventuallymigrated to the wells approximately 1.609 to 3.218 km southeast of the installation boundary.

The recommendation in this 1980 report is that the Iowa Army Ammunition Plant should expandits present water quality monitoring program to include analyses of surface waters on a fixedschedule basis at locations on the installation in addition to NPDES monitoring points, especiallyat points where streams exit the installation.

1980 (Ref. 257)Annual Supplement to Unit History, Iowa Army Ammunition Plant, Fiscal Year 1981,Covering the Period of 10/1180 through 9/30/81

Two new items, the M207EII-TOW Warhead and the M248 Patriot Warhead, were produced atLine I during FY81. The Hawk, Chaparral and Stinger Warheads were also produced as well asthe 155 mm, M7181M741 throughout the period.

Military Construction Army (MCA) activities were significant in FY81. Projects included acontaminated waste processor and explosive waste incinerator to go into operation in 1982 toreduce air pollution. Another MCA project will reduce land and water pollution through majorimprovements to the main sewage treatment plant and by diverting polluted runoff flows to theplant's sanitary sewer system.

There were three recordable property damage accidents in FY81, with damages totaling over$51,000. They included a production line fire resulting in $47,500 in damage to an assemblyline torquing press, a detonation in a remotely controlled production line press, and vandalism toa plant entrance gate. There were no personnel accidents. By the end ofFY81, employees hadworked nearly 7,000,000 hours without a time-lost injury or fatality This record was the bestachieved at the plant since operations began in 1941. [257]

1981 (Ref. 286)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1982, Covering thePeriod of 10/1181 through 9/30/82

Production on a new item, the M209\7E2 TOW-2 warhead, began in September 1982. Sixpresses and assembly equipment were installed in Building 1-10. Other production on Line I

Line 1 Work Plan for Supplemental RJ.doc - 9/20/2001 Page 2-67Historical Site Research and Review

included the M207EI I-TOW, M248 Patriot, M250 Chaparral, and M258 Stinger Warheads.Other production included the 155rnm M7181M741 projectile.

In other items of interest outside of Line 1, the open burning of explosive wastes ceased duringFY82 at the direction of the State ofIowa.

Two accidental production press explosions occurred. Line or location was not stated in thereport.

I~AAP continued its accident-free record with no recordable disabling i!!i..uries and, by the endofFY82, employees had worked more than 8,600,000 hours without a lost-time injury or fatality.This record was the best achieved at the plant since operations began in 1941.

In May 1982, the IAAAP achieved a safety record of four years without a disabling injury. Thisnoteworthy goal remained intact at the end of the fiscal year.

1982 (Refs. 287 and 296)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1983, Covering thePeriod of 1011/82 through 9130/83

Production was devoted to the M207El I-TOW, M207E2TOW-2, M248 Patriot, M250Chaparral, M258 Stinger, and M265 Hellfire Warheads and the 155mm M718-M741 projectile.

Other items of interest outside of Line 1, there were no recordable "lost time" injuries and, by theend ofFY83, plant employees had worked more than 10,000,000 hours without a disablinginjury or fatality.

There were seven recordable property damage incidents in FY83. Four production line incidentsresulted in nearly $9,000 in damages. A $9,000 accident involved a melt grid unit.

Reconstruction of the Building 1-04 Chemical Laboratory, which had been damaged in anexplosion, was completed in FY83.

1984 (Ref. 288)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1984, Covering thePeriod of 10/1183 through 9/30/84

Production work was accomplished on the I-TOW, TOW-2, the M718/M741 RAAM, Patriot,Chaparral, Stinger, Hellfire, Hawk and M-74 and M-75 GEMSS (Ground Emplaced MineScattering System) items. Hawk loading operations were resumed during the period after noproduction activity in recent years. Both inert and HE pours were initiated on FASCAM (Familyof Scatterable Mines) at Line 1.

The IAAAP's all-time safety record, extending 2,104 days without a recordable disabling injury,ended on February 28, 1984 when a production workerfell and broke an ankle while handlingboxes of explosives on Line 1. It was the Plant's first recordable disabling injury since May 24,1974; the accident-free period covered 11,256,035 hours.

Another employee, working in Yard C, was injured on March 26, 1984, when he fell from a dockand fractured a neck bone.

Other notable incidents not Line I-related, included eight recordable property damage incidents.Two were caused by cold weather (resulting in $91,197 in damages), and four incidents involved



remotely operated presses. There was an explosion in an X-4 detonator loader, and a "flash" inan M650 projectile. Total property damages exceeded $41,000.

1985 (Ref. 289)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1985, Covering thePeriod of 10/1184 througb 9/30/85

TOW production included output ofI-TOW and TOW II billets, along with modified bodies andwarhead parts, for use in improved Picatinny (Arsenal in Pennsylvania) and MICOM warheads.Work was also being carried out on the M258 Stinger and the M248 Patrtet. Maintenance workcontinued on press tooling equipment for the M7181M741 projectiles. An explosion in April1945 resulted in damage to an M8\718 booster press and a reduction in press speeds to reducethe chance of a similar incident.

Other information not completely related to Line 1 includes the Iowa Department of Water, Airand Waste Management (IDWAWM), in conjunction with AEHA, conducted a groundwatermonitoring program. The testing was mandated by the IDWAWM and the EPA. The twoagencies directed this activity after measurable qualities of solvents were detected in on-postmonitoring wells. Thirty-one off-post drinking water wells, as well as a retest of on-post wells,were included in sampling performed for explosives and solvents. Results of the analysis, bothon and off the post, indicated no measurable contamination.

In June 1985 EPA (Region 7, Kansas City) conducted a RCRA Hazardous Waste ComplianceInspection. The State ofIowa had two inspectors on hand for observation purposes. As ofJune 30, 1985, the State ofIowa withdrew from its responsibilities under RCRA and will nolonger inspect for or enforce RCRA laws.

Three plant workers sustained recordable disabling injuries in FY85. An electrician fell in ahallway and injured his back, an inspector's left wrist was caught in assembly line machinery,and a millwright's shoulders and chest were injured when he became caught in a conveyormechanism. An explosion in a Line 1 press caused $3,300 in damages, while a railroad accidentin Yard D cost an estimated $40,000 in damages.

1986 (Ref. 290)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1986, Covering10/1185 througb 9/30/86

I-TOW and TOW-II operations were moved from Building 1-40 to the north end ofBuilding 1-12 to allow a subcontractor to work in Building 1-40. Inspection facilities forFASCAM main charges and boosters were moved from Line 1 pressing cells to a centralizedlocation in Building 1-100-1. Inspection equipment for the M207ES warhead was installed inBuilding 1-12. Warhead equipment for the Chaparral, Stinger, Patriot, and the Hawk wasinstalled. LAP operations were begun in Building 1-12 with no problems. The move was madeso work could be done on the roofof Building 1-40.

In May 1986, the IAAAP was notified by an Armament Munitions and Chemical Command(AMCCOM) attorney that an agreement had been worked out with IDWAWM on sites that thePlant had proposed for listing on the Registry of Management or Uncontrolled Hazardous WasteSites. The landfill area will be Abandoned or Uncontrolled Hazardous Waste Sites. The landfillarea will be reduced from 640 acres to 10 acres under the agreement. The Line 800 Pink WaterLagoon area will be reduced from 640 acres to 30 acres, and the fonner containment area west of

1987 (Ref. 291)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1987, Covering10/1/86 througb 9/30/87

TOW-2A Warhead production was initiated during this period. Other items still being producedon Line 1 included the I-TOW, TOW-2, Patriot, Chaparral, and Stinger Warheads and the155mrn M718/M741 Projectile.

In other items of interest, there were no reportable disabling injuries. A frozen steam pipecaused $1,766 in damages in Building 1-77.

The Federal Facilities Compliance Agreement (FFCA) issued by EPA on August 22, 1986, wasnegotiated between EPA, Region VII in Kansas City, AMC, AMCCOM and the IAAAPelements in FY87. It is estimated that DOD and EPA will have the FFCA negotiated and readyfor final endorsements in FY88. The modifications required to complete the RCRA Part Bandother areas ofRCRA interest were the primary issues contained in the FFCA. A contract wasawarded to the Corps of Engineers, Fort Worth District, in FY87 to completely revise theIAAAP RCRA Part B permit application. This document will be submitted to EPA in September1988.

1988 (Ref. 292)Annual Historical Review, Iowa Army Ammunition Plant, Fiscal Year 1988, Covering10/1187 througb 10f30/88

Line I production continued with the I-TOW, TOW-2, TOW-2A, Hawk, Patriot, Chaparral, andStinger Warheads and the 155mm M7181M741 Projectile. Production was initiated on the120mm M829El during September 1988. Numerous special tests were conducted on theTOW-2A to enhance the warhead performance.

Other items not directly related to Line 1 included signing by the IAAAP Commanding Officerof the FFCA, which was transmitted to EPA, Region 7 for signing by EPA officials. (Date oftransmittal was not included in the historical document reviewed.)

The Toxic Chemical Release Inventory Reporting Fonn (EPA Fonn R), required for fourchemicals in use at IAAAP that met the threshold of 10,000 pounds each for 1987 reportingrequirements, was completed and transmitted by letters to the Iowa Department ofNaturalResources and EPA on June 28, 1988. The following chemicals were reported: chlorine, xylene,acetone and 1,1, I-trichloromethane.

There was one recordable disabling injury in FY88. Three recordable property damage accidentsin FY88 occurred on Line 1. They were a detonation while pressing booster rings inBuilding 1-67-2, detonation while consolidating PBXN-5 for the GEMSS Program in



Building 1-18, and detonation while consolidating PBXN-5 for the Remote Anti-Annour Mine(RANIM) Program in Building 1-67-2.

1988-1989 (Ref. 441)Comments from John Jamison, Safety and Security Manager, 1988-1989 Time Frame.Mr. Jamison's remarks were summarized in a report covering all areas of the Iowa ArmyAmmunition Plant. Mr. Jamison is now deceased.

Mr. Jamison's comments relating to Line 1 are as follows:-

General building contamination from cleanup and washdown.

Questions asked about any contamination that might have occurred with former AEC operationsand previous Annyoperations. Replies other than explosives, no radioactive contamination asall units (were) sealed.

A lot ofbarium nitrate handled in the 1-60 building. There was also anthracene or p-naphthaleneused as an anti-cracking additive and also some inert load formulations which were toxic(carcinogenic, impurities); green dye used, (LX-90) (FEFO) is believed to be toxic but readilydecomposed.

There was DU in some areas not encased, and although swipe tests were negative, there could beoxides from DU. Potential areas would be (Buildings) 1-11, 1-13, 1-12, 1-40, 1-61 and 1-63.Tests so far have not indicated any activity inside the buildings.

Explosive areas to consider: Entire line should be considered because at one time there weresump troughs leading from melts, 1-10 Building, machining operations at 1-12, 1-40 and1-100 Buildings and all that explosive-contaminated water went into the creek and the BrushCreek Impoundment. Many times troughs ran over and there was heavy explosivecontamination.

1998 (Ref. 293)Supplementary Plant History Folders, Iowa Army Ammunition Plant, Burlington, Iowa,Historical Files, 1942-1996

The only information of Line 1 operations stated that "brighter news came in May 1956 when itwas announced that the Atomic Energy Commission facilities would be expanded here.Additional production facilities were to be built on Line 1, and a storage area was to berehabilitated. It was also announced that radioactive materials were to be introduced intoproduction processes here."

1998 (Ref. 174)Historical Summary, Iowa Army Ammunition Plant, Burlington, Iowa, Historical File9/2/45 - 7/1/51

This report covered a variety of areas: historical summary of the IAAAP, maps, transition period(following the end of World War II), different items manufactured, reconditioning of munitions,renovation of fuses, demilitarization of shells, renovation plant (Line 800), the AmmoniumNitrate Program, and resumption of new products.

2.4.1.1 Laboratory Operations

January 1980 (Ref. 141)U. S. Army Toxic and Hazardous Materials Agency Installation Assessment ofIAAAP

The IAAAP laboratories are located in Buildings 1-03 (Explosives Laboratory) and 1-04(Environmental Testing Laboratory) of Line 1. The laboratories provide quality control andgeneral support for IAAAP. The laboratories have conducted several research and development(R & D) programs over the years (e.g., electrolytic disposal oflead azide, activated carbonregeneration for red water control). -,,-

Ordinary wastes are disposed ofvia the sanitary sewer system. All hazardous wastes are shippedoff site for treatment and disposal.

Building 1-03 has four fume hoods. In Building 1-04, North Chemistry Laboratory has fivefume hoods, and the water quality laboratory has three hoods. The exhaust stacks of these hoodsfree vent the laboratory solvent vapors.

The IAAAP Plastics Laboratory is also located on Line 1 in Building 1-53.

In the past, other buildings on lAAAP were also used as laboratories for various operations.

The' liquid/solid contamination potential from the current laboratory activities is nil, assumingproper utilization of the current hazardous waste program. The activities in the older laboratoriespredate the present laboratory employees, and no recordsofthe waste disposal techniques werefound.

2.4.2 Historical Review of Environmental Investigation Documents

The environmental investigation documents consist of fourteen subject areas. These include:chemical and explosive waste generation, beryllium investigations, radiological investigations,MaCA investigations, environmental monitoring, holding/settling ponds for industrial wastewater, waste management, sump removal, above-ground storage tanks, health and protectionsurveys, documented accidents and explosions, newspaper articles, historic properties andarcheology, and significant environmental investigation documents. The Federal FacilityAgreement under CERCLA, the JAYCOR Preliminary Assessment and Remedial Investigation,and the ROD are summarized under this subject area. The JAYCOR RI sampling resultscontained in this document was used to guide some ofthe sampling locations for the Samplingand Analysis Plan.

2.4.2.1 Historical Chemical and Explosive Waste Generation

01 October 1941 (Ref. 113)Complete Rounds Manual, Iowa Ordnance Plant, Day & Zimmerman, Inc., Engineers

This document is a training manual for new employees ofIAAAP (formerly known as IowaOrdnance Plant). This report outlines the potential contaminants due to ammunition production.



The following are potential contaminants due to production:

High Explosives:

• TNT

• Tetryl

• TNA

• Lead azide

• Mercury fulminateAmatoI

-~

•• Picric acid

• Ammonium picrate

• Dynamite

Low Explosives:

• Nitrocellulose

• Black powder and primer mixture are mechanical combinations of powdered substances. Atleast one substance must be a material that bums easily (charcoal, antimony, sulphide, orsulfur)

• Anny black powder is charcoal, sulphur, and potassium nitrate.

• Primer mix (potassium chlorate)

The following are ammunition production components with their potential contaminants:

• Shrapnel balls are composed of lead alloyed with antimony.

• Relays are small aluminum cylinders filled with lead azide.

• Delay is a pellet of compressed Army black powder.

• Artillery primer is a percussion element with a brass cylinder, charged with black powder.The strength of a primer mixture can be further increased by adding a little mercuryfulminate, lead azide, or TNT - only 5 percent or so.

• Booster cups and boosters contain a large charge oftetryl or some other brissant (explodedby crushing) explosive.

• Cartridge case is a propellant charge usually smokeless powder and is loaded in a cylindricalbrass container. In the bottom of the cartridge case is an artillery primer containing Annyblack powder.

• Adhesive zinc oxide tape applied with friction tape was put around the shipping/storing boxto exclude air and moisture.

• Before the pouring of melt into shells, 15 percent caustic soda solution was used to cleanempty shell bodies. Solution was sprayed into the shell through a spray nozzle to remove dirtand grease.

This document summarizes the effluent problems at the Burlington, Iowa, Plant, reporting thatthe number one problem is the HE waste disposal problem. The quantities ofHE involved fromDivisions A and B are listed along with the amount of sump water taken to the leaching fields. Itreports that HE and inert waste are collected in sludge settling tanks where the water passesthrough carbon columns and emerges as clear effluent. Other explosives are collected in boxesand sent to the burning field along with the waste sludge. Contaminated paper is burned andmetal parts and explosives are flashed. It also reports that no red water ffOm TNT is admitted tothe stream or Brush Creek.

2.4.2.2 Beryllium Investigation Documentation

1 September 1970 - 4 October 1973 (Ref. 335)"Determination of Beryllium Concentration in the lAAAP Area Using Atomic AbsorptionAnalysis~" Technical Report No. 197-A through No. 197~ Part 6Burlington AEC Plant

The results obtained from swipes taken in the lAAAP area using atomic absorption analysis aretabu.lated in these reports. The beryllium content was relatively high in samples taken very nearthe sanding and case areas. Technical Report No. 197 Part 3 suggests that the contamination isdue to beryllium dust on incoming component parts that were not adequately cleaned prior toshipment and not from the small sanding operation conducted at the Burlington ABC Plant.Analysis of all beryllium samples of all the reports were performed using atomic absorptionspectrophometers, which provide a highly specific and convenient means to monitor exposure ofLine I personnel.

In July 1970, Technical Report No. 197, Part 2, samples from Building 1-61 Bay E had hits ofberyllium before cleaning up to 15 micrograms, with results lessening to 0.1 after cleaning thearea swiped. However, other samples were above the allowable limit up to 310 micrograms. Inaddition, a case swiped as received had 6.5 micrograms of beryllium.

Results from Technical Report No. 197, Part 3, reported hits above the allowable limit inBuilding 1-61, Bay K, on the table in November 1970, and in cases up to 5.3 micrograms inMarch 1971. Building 1-61, Bay M, had hits on the stand-scales, floor, and table in November1970, and had hits up to 1,000 micrograms on a urethane foam table cover in April 1971, withswipes recording 5.85 micrograms after cleaning the entire bay on the same table.Building 1-63-3 had hits on the stands up to 3.55 micrograms. Building 1-63-4 had hits fromcarts up to 16.0 micrograms and up to 1,000 micrograms on a urethane plastic table cover.

In Technical Report No. 197, Part 4, Building 1-61, Bay K, had hits up to 11.9 micrograms onswipes from shells after they were cleaned. Building 1-61, Bay M, had a hit of3.9 microgramson the east table. Building I-II (green room) contained shells with hits of 16.0 micrograms inJuly 1971 and 12.0 micrograms in September 1971. Building 1-63-5 had a swipe on gross area58 of6.0 micrograms.

Technical Report No. 197, Part 6, only reported one hit of beryllium above the allowable limit inBuilding 1-63-3 in the air filter. All other swipes during this swipe sampling analysis were wellunder the appropriate levels ofberyllium.

2.4.2.3 Radiological Investigation Documentation

23 December 1969 (Ref. 343)Letter: Radioactive Waste DisposalBurlington AEC Plant

This letter references a memorandum dated November 18, 1969 concerning Radioactive WasteDisposal. In response to the request in the said letter, D-38 and U-238 residue material wasteincluding plutonium contaminated waste is to be packaged for shipment in accordance withSOP S-132. Less than 0.001 Ci ofPu-238 and 0.5 Ci ofD-38 have been discarded to date(19q9). It is noted that no waste was discarded in 1965 through 1967. In 1968, less than 0.016grams ofPu-239 (4.71 cubic feet or 70 Ibs. gross weight of package) was sent for disposal. In1969, 1.051 kg ofD-38 (25.60 cubic feet or 3827 lbs. gross weight) was sent for disposal. SOPS-132 is not attached.

Note: There is no documentation of any operating procedures that necessitated the wastemanagement of Pu at the IAAAP in this document or other documents which mention the use ofPlutonium (Refs. #351, #353). This information is most likely located in documents eitherclassified or unclassifed, yet not accessible.

Waste management practices ofPu include the storing ofPu in plastic bags in a 55-gallonshipping container. In 8 years, less than one drum of these wastes was accumulated. It is alsoreported than a small quantity ofPu239 wastes was sent to the Pantex AEC facility in Amarilllo,Texas.

17 September 1977 (Ref. 434)Trip Report by EPA PersonnelLine 1 & Firing Site

This document consists of a letter transmittal to the Commanding Officer of the IAAAP from theEPA. A visit to the Line 1 facility indicated that at no time was there a radioactivity release inthe Line 1 building. According to this visit, a detailed swipe survey conducted upon completionof operations detected no radioactivity.

27 January 1986 (Ref. 302)Letter: Real Estate DivisionIAAAP

This letter is in response to a letter dated January 13, 1986, from the Plant Manager to theAssistant Director for State Agreements Program regarding the status of the IAAAP. It reportsthat the 19,105.04 acres are subject to exclusive (Federal) jurisdiction and that 41.3 acres aresubject to proprietary (State) jurisdiction. It is noted that based on this jurisdiction, IAAAPshould continue to be licensed by the Nuclear Regulatory Commission (NRC) and any use ofsource and byproduct material in the exclusive jurisdiction area will continue to be under NRCregulation. The use of radioactive material in the acres designated proprietorial are subject toState regulation.

9 May 1997 (Ref. 142)Letter: Multiple Removal Actions - Transmittal of FinalRadioactive Isotope Analytical ReportIAAAP

Enclosed in this letter is the final Radioactive Isotope Analytical Report for the groundwatersamples obtained from the Inert Disposal Area (IDA) gas vents. Four gas vents showed grossalpha and/or gross beta levels above the maximum allowable levels for community watersystems. Attached are tables that summarized these results. Additional water samples werecollected for gamma spectrometry in 1997 from the four gas vents that showed elevated grossalpha and gross beta levels. The purpose of the additional sampling was to try to determine thesource of the elevated levels.

Based on the analytical results, the report recommendations suggest that the radionuclideactivities are within normal background levels for IAAAP and that the water removed from theIDA gas vents should not require treatment for radionuclides. However, arsenic, barium,beryllium, cadmium, chromium, and vanadium levels are exceeded in one vent. All of the ventshave elevated levels of volatile organic compounds (VOCs) and semivolatile organic compounds(SVOCs).

1 March 2000 (Ref. 117)Letter: Use ofD-38 at IAAAPIAAAP

This letter summarizes the use ofDU at IAAAP from the 1980s through the 1990s. Theproduction of 120mm ammunition that includes a component made ofDU began in 1985,producing over 300,000 rounds. The demilitarization of 105mm ammunition that also involves acomponent made ofDU began in 1996 with over 200,000 items being recycled. It is reportedthat these activities have been conducted on production Lines 1, 2, 3, and 3A, and the items have



been stored in sealed containers throughout the Plant. Attached is Amendment No.12 to theNRC Material License No. SUC-138!.

2.4.2.4 Methlene-Bis-Ortho-Chloroanline (MOCA) Investigation Documentation

August 1971 (Ref. 310)Technical Report from Dupont ChemicalsMOCA - A Diamine Curing Agent for Isocyanate-Containing Polymers

This document is a product description ofMOCA, a diamine curing agent for isocyanatecontaining polymers. It is described as a hindered, aromatic diamine, which yields convenientworking life and good vulcanization properties with liquid urethane elastomers. It is also aneffective curing agent for epoxy resins and provides a curing system for blends of liquid urethanepolymers and epoxy resins.

It is recommended that for the safe handling of MOCA, comprehensive industrial hygiene andthe recognized industrial safety principles for handling reactive organic chemicals be followed.

All persons handling MOCA should wear clothing designed to avoid direct skin contact, andefficient ventilation should be provided in all work areas.

MOCA shows the general toxicity characteristics of aromatic amines and may, if taken into thebody, produce cyanosis. The approximate lethal dose for rats was listed as 1,000 mglkg withsmaller daily doses causing some pallor, cyanosis, depression of growth, and abnormalities in theblood and urine. Carcinogenicity tests observed evidence of liver and lung cancer in rats both inshort and long-term studies. Mammary tumors in females were also observed.

Medical surveillance of personnel detected no manifest of symptoms derived from MOCAexposure; however, traces ofMOCA were present in urine samples. The severity of exposurewas effectively reduced by ventilation, respiratory protection, protective clothing, and clean dustfree work areas.

The practices instilled by Du Pont upon manufacturing MOCA are discussed in this document.Du Pont employees wear fresh, company-laundered clothes and shower prior to changing intostreet clothes. Long-sleeved shirts, neoprene or butyl rubber gloves, and dust respirators areworn whenever direct contact with MOCA dust occurs. Side shield safety glasses, goodventilation, and strategically located hoods are present throughout the work areas. All worksurface areas are cleaned and flushed with water at appropriate intervals. Air-supplied facemasks, neoprene or butyl gloves, and aprons are required for operations involving exposure tofumes from molten MOCA. Proper storage and thermal breakdown ofMOCA are also included.

December 1971 (Ref. 311)Technical Article from the American Industrial Hygiene Association JournalMOCA: Evaluation of Hazards and Exposure Control

This document discusses the recent reports that indicate a high incidence of liver cancer in ratsexposed to MOCA in a protein-deficient diet and of lung cancer with MOCA in a normal diet.No clinical evidence of malignancy has been observed in dogs during the third year of a six-yearstudy. Although urinary excretion ofMOCA has been significant in operators and mechanicsassigned in the manufacturing area, close medical surveillance has detected no manifest sign orsymptoms. Skin absorption from direct contact was considered to be the major source of



absorption. Efficient precautionary ventilation, respiratory protection, and protective clothingeffectively controlled exposure. A threshold limit value for MOCA in air alone would notprovide an effective control basis. However, biological monitoring by urine analysis doesprovide a reliable and expedient control system.

6 December 1972 (Ref. 313)Letter: The Control of Toxic Materials

This memorandum is to Managers of AEC Field Offices in reply to a recent meeting of theexecutive council of the Oil, Chemical, and Atomic Workers Union. Several allegations weremade that workers were being denied knowledge of the properties of the chemicals with whichthey were working. This letter brings attention to the Occupational Safety and HealthAdministration (OSHA) Law and gives suggestions to formulating a program for improving theavailability of information and controls over toxic materials in AEC programs.

Attached is a memorandum dated October 5, 1973, whose subject is also the control of toxicmaterials, in particular, the Emergency Temporary Standard for Certain Carcinogens.

It notes that it is the responsibility ofthe contractor to determine the toxicity of the materialbefore placing it in use and to take appropriate steps to protect employees and the environment.In addition, the contractors must be aware of the additional carcinogens placed on NationalInstitute of Occupational Safety and Health (NIOSH) yearly Toxic Substances List. Thementioned attachment in this letter is not attached.

3 May 1973 (Ref. 309)Federal Register Extraction, Vol. 38, No. 85

This document is a result of a petition for an emergency temporary standard submitted by theOil, Chemical, and Atomic Workers Union and Health Research Group. The petition containedrelevant information on the danger of exposure to 10 of the carcinogens listed in the standard.The petition was published in an earlier Federal Register publication requesting furtherinformation from interested persons. More than 50 written comments were received. It wasdetermined that exposure to 14 carcinogens listed in the emergency temporary standard are toxicand physically harmful, that employees are presently exposed, and that this standard is set forthto protect the employees from such exposure.

Suggestions and regulations for employers are listed, including access to controlled areas,decontamination, proper posting, waste disposal, medical surveillance, ventilation, reporting, etc.

11 May 1973 (Ref. 308)Letter: Emergency Temporary StandardDu Pont Chemicals, MOCA

This letter to Du Pont customers is in response to the emergency temporary standard pursuant toOSHA requiring a zero exposure of employees engaged in the manufacture and subsequenthandling of MOCA. It is noted that the Secretary of Labor has announced this standardbecomes effective May 18, 1973, and requires zero exposure on June 4, 1973. The lettersuggests that Du Pont may not have the ability to continue manufacturing this product, andtherefore, will meet with the Secretary of Labor to review the matter and seek an extension ofeffective date or other appropriate relief.

17 May 1973 (Ref. 307)Letter: Emergency Temporary StandardDu Pont Chemicals, MOCA

This letter is from the Du Pont Rubber Chemicals Product Manager to Du Pont customerspertaining to MaCA The letter reports that Du Pont met with the Department of Labor. As aresult, Du Pont believes that the manufacturing operations can be brought into compliance toproduce MaCA. It is noted that the Department of Labor indicated that interpretation of thestandard with respect to individual plant problems could be discussed with regional OSHAoffices.

22 May 1973 (Ref. 334)Plant Directive: OSHA Emergency Temporary StandardBurlington AEC Plant

This directive summarizes the Emergency Temporary Standard and acknowledges the use ofMaCA in some production operations at the Burlington AEC Plant. The letter goes on to saythat all employees of the Plant whose work involves exposure to MaCA are hereby advised ofthe occupational hazards noted in the OSHA emergency standard. It notes that while laboratorytests have demonstrated that MaCA causes cancer in rodents, there is no evidence to substantiatesimilar effects on humans or other animals. However, in recognition of the OSHA Standard, thePlant has temporarily discontinued use of MaCA locally, pending further hearings, analysis,and/or implementation of suitable controls.

17 May through 12 Jun 1973 (Ref. 304)TWX Messages on Restricted Use ofMOCABurlington AEC Plant

The TWX Messages are a series of informative messages to the Burlington AEC Plant and otherAEC Plants about the Emergency Temporary Standards on Certain Carcinogens. It is requestedthat any of the listed carcinogens used in the facilities be listed. In addition, a request to indicatethe impact on operations in those cases where you cannot comply with the emergency standardsby specified dates. It is noted to include vendor considerations to the extent possible.

30 May through 21 September 1973 (Ref. 317)Air Analysis Taken Over Mixes ofAdiprene/MOCA Formulations

This document contains the tabulated results of air sampling and analysis results. All results arenegative except for samples taken over hot MaCA for 10 minutes and 20 minutes using an MSAAir Sampler, Acetone Getter in Building 1-04. An MSA sampler in Building 1-61, Bay J, testedpositive for MaCA as well as swipe samples taken in Building 1-53 inside a glove box near abalance.

4 June 1973 (Ref. 305)Health and Safety Topics - Area Managers/Plant Manager MeetingBurlington AEC Plant

This memorandum attaches the remarks of the Assistant Manager for Operations of the AEC onthe OSHA Emergency Temporary Standard, Management Oversight and Risk Tree (MORT),and Pollution Control Guidelines. It is stated that publication of this standard, for all practicalpurposes, brought production to a screeching halt.

II).



The Standard required enough significant changes in the processing and handling ofMOCA thatthere was no way for most of the AEC facilities using the material to comply. Of the14 carcinogens listed in the Standard, 13 were used in at least of the AEC facilities, 7 used atonly one plant, while 3 were used at 5 or more locations. MOCA was involved at 8 of the sites.

It is reported that, due to discussions between AEC Headquarters and the Department of Labor,the Emergency Standard requirements have a more relaxed interpretation. MOCA was noted asthe principal "culprit" as far as the operations were concerned. It is described as yellowish solid,marble-size pellets, as supplied by Du Pont, who has been producing the material since 1962.Early evidence of the carcinogenic properties ofMOCA came from Germany. A six-year DuPont study indicated tumor development in rats, but not dogs. In addition, a project to determinethe extent of exposure for employees assigned to the manufacturing plant, which began in mid1967, indicated presence in the urine of employees, but no untoward health effects fromexposure and subsequent processing ofMOCA in body were identified.

Some clarifications of the Standard's requirements include the following: It does not apply tofinal product after MOCA has chemically reacted with other ingredients, it does not apply whenMOCA is in a closed, sealed container, enclosed hoods and glove boxes are consideredthemselves controlled areas, no respirators or supplied-air suits are required when work is donein hoods or glove boxes, supplied air must be worn when there is direct, known exposure, nolevels for decontamination have been established, contaminated clothing may be processed instandard washing machines, effluent releases are under the purview of the EPA, postings ofwarnings must be complied with, and the medical program report may be very brief resumes.

Instructions for decontamination and modification of operations using good industrial hygienepractices and common sense are suggested. It is noted that AEC Headquarters will establishbetter means to detect problems associated with chemicals being investigated. A list ofsuggestions for contractors is also included, for example, catalog toxic materials, look for andevaluate alternative materials, etc. The focus on the final Emergency Standard remarks isprotecting AEC against probable restrictions on the use of materials.

7 June 1973 (Ref. 303)MOCA AnalysisBuilding 1-04

This document describes the techniques for detecting or measuring the presence ofMOCA invarious environmental situations. It notes an indicator solution used by Pantex which consists offurfural and acetic acid. This provides a deep red color upon contacting MOCA.

An analytical procedure for determining the concentration ofMOCA in urine was obtained fromDu Pont to assure Medical Department concurrence. The Development Chemistry Section hasdeveloped a gas chromatography technique utilizing an electron capture detector, which is moresensitive than the Pantex method.

A list of standards, blanks, and samples taken and/or prepared and any available results aretabulated in the document. All tests resulted in negative results except for a two-part sealantsystem used in the Assembly Area that contained 30 percent MOCA.



11 June through 22 August 1913 (Ref. 321)TWX Messages: Application of the Emergency Temporary Standards

The initial TWX-Message offers guidance for compliance with the Emergency TemporaryStandard such as appropriately posting all controlled areas. It is requested that medicalsurveillance reports be submitted along with cost estimates for the updates to comply. Asubsequent TWX Message requests for the inclusion of reports on monitoring and reporting.

A July 3, 1973, TWX Message reports the agreement with the Department of Labor that ininterpreting the OSHA Emergency regulation MOCA is no longer considered MOCA after thematerial has been mixed with a resin. This interpretation allows for certain operations withMOCA to resume. Although it is noted that the MOCA mixture still has the concentration of1 percent referred to in the OSHA standard, the MOCA-resin-mix is considered not likely torepresent an inhalation hazard. The contractor is to provide protective clothing for skin to assurethat the polymer does not come in contact with an employee's skin. A subsequent messagereports that the Department of Labor disavowed concurrence with AEC: hoods and glove boxesmay not be considered controlled areas, and solutions and compounds consisting of more than1 percent by weight ofMOCA may not be excluded from the provisions ofthe standard.

The original Emergency Temporary Standard is attached in a previous TWX Message.

15 June 1973 through (Ref. 320)Letters and Memos: Reporting Requirements to ALO and OSHA, andPresent Monitoring and Analytical Methods UsedBurlington AEC Plant

This letter begins explaining difficulty interpreting medical surveillance requirements of theOSHA Emergency Temporary Standard. Monitoring of air samples in the operator's breathingzone is accomplished by using a calibrated MSA pump. All results to date have been negative.Swipe samples are obtained using acetone and cotton swabs, and the acetone is analyzed as anatmospheric sample. Six out ofnine of these samples did contain MOCA at varying levelsranging from 0.0 to 68-micrograms/square yard.

A letter dated June 12, 1973, reports that the analysis of urine samples can begin anytime, butsampling intervals are not firmly established and indication of time after exposure for samplingis unclear. Quotes from Du Pont's Article in "American Industrial Hygiene Journal" areattached. It is reported that some urine specimens had almost a complete loss ofMOCA during48 hours of standing. The addition of citric acid reduced the pH to 3 and almost completelyeliminated the decomposition.

An interoffice memorandum dated July 25, 1973, contains a list of areas requiring cleaning andpainting in Building 1-53, Bays B and C; Building 1-40, Bay J; Building 1-19-7; andBuilding 1-12, Bay F.

Three company bulletins dated August 7, 14, and 21, 1973, are included as well. The bulletinsare non-scheduled workdays due to Adiprene-MOCA processing problems. The August 21,1973, bulletin lists two exceptions for workers, the sub-area 1-40 and I-lOS 8-4:00 and4:00-12:00 shifts and the sub-area prep, melt, and cast 8-4:30 shift.

An Outgoing Telecommunication Message consists of the costs for compliance with the OSHATemporary Standard on Carcinogens per request of the USAEC, ALO. It is noted that glove

I'll'



boxes will be available within two weeks and laboratory hoods with dehumidification systems intwo months. All bonding operations on the 66 and 69 Programs (except for case grommetbonding), 71 Program, and the 68 Program operation involving WS12391 are not in compliancewith the July 27;1973, Standard.

Another Outgoing Telecommunication Message includes information regarding a MedicalSurveillance Program to be instituted for personnel working at the glove boxes and hoods. Theprogram will be based on Du Pont medical programs. Twice a month and not less than 10 daysapart, all personnel who are working in controlled areas will have urinalysis for thedetermination ofMOCA levels. Monthly intervals on those persons will include blood count toinclude white blood cells, differential hematocrit, red blood cells and hemoglobin sedimentationrate, and a urinalysis. Every six months an automated group of tests will be performed on thosepersons whose name appears on the monthly list for chemical analysis ofkidney and liver.Annual chest X-rays and a regular physical will be performed on all persons whose nameappears on a monthly basis.

A third Outgoing Telecommunication Message lists the Adiprene-MOCA formulations (in partsby weight) as follows: Adiprene 100.0, MOCA 16.5, and acetone 49.5. Other formulas arelisted, but this lists the highest MOCA concentration. The mixture of the above formula isapplied with a brush from a container about 3.5 inches by 2 inches in diameter using 50-100 gquantities. The other formula mixtures are either sprayed or applied with a roller from a shallowflat container. A repair mixture with 16.69 ofMOCA is applied by hand or spatula by operatorswearing impermeable gloves. About 7,000 g of the foremost mentioned formula mixture isdispensed per week. The other mixtures dispense a total of2,905 g per week. Samples taken ofall the mixtures indicated MOCA above the lower detection limit of 5 nanograms.

15 June 1973 (Ref. 314)Letter: Planned Medical Surveillance ProgramBurlington AEC Plant

This letter was submitted regarding a request for a report on the planned medical surveillanceprogram at Mason & Hanger. The planned program includes getting the name and badgenumber of each individual who has worked in a controlled area during the previous month andforwarding them to the Medical Department. The Medical Department will perform tests atmonthly intervals on those persons. The tests will include blood count, differential hematocrit,red blood cell and mercury sedimentation rate, and a urinalysis. Every six months an automatedgroup of tests will be performed on those persons whose name appears on the monthly list foralkaline phosphates, bilirubin, BUN, calcium, cholesterol, glucose, inorganic phosphorus, LDH,SGOT, total protein, albumin/globulin, and uric acid. Annual chest X-rays and FEV will beperformed all persons whose name appears on a monthly basis. Twice a month and not less than10 days apart, all personnel who are working in controlled areas will have a urinalysis for thedetermination ofMOCA levels.

17 August 1973 (Ref. 315)Letter: Comments on Temporary Emergency StandardBurlington AEC Plant

This letter includes comments from the Mason & Hanger Plant Manager to the Manager of theAmarillo Area Office about the Temporary Emergency Standard. It states that the Standard iswritten to apply to manufacturers and users oflarge quantities ofthe cancer-suspect agents and



that no consideration is given to operations where only small amounts are used. Anothercomment concerns employees taking showers after their last daily exit from controlled areaseven though they wear their street clothes all day under smocks which they wear home. It isstated that there will be a great diversity in the opinion on the definition of adequate protectiveequipment. The size or limits of a controlled area are not well defined either, but are left to thediscretion of the user. There is confusion as to who should be added to lists of employeesentering a controlled area as well.

Other concerns include the lack of requirements for shower rooms, proper waste disposal ofMOCA, and guidance for medical surveillance programs and monitoring programs. Thedefinition of a carcinogen changed from a composition containing more than 1 percent by weightof any listed substances to any mixture containing more than 1 percent by weight of any of thelisted substances. It is suggested that a case could be made that any mixture with air, where thelisted substance was less than 1 percent by weight in relation to the weight in the air in which itwas suspended, is exempt from the Standard. Using this rationale, it states that operations couldbe reinstated and a TLV in breathing air could be established at 0.024 ppm for MOCA.Additional concerns include a change in decontamination and ventilation wording in the revisededition of the Standard.

27 August 1973 (Ref. 333)Record of Telephone CallAdiprenelMOCA Substitute

This record reports that the L315/Polyol mixture is looking like a good substitute for MOCA.The various ingredients are compatible with explosives, but more tests need to be run. The newadhesive will likely not go into WR production for 2 to 2~ months. It is requested that allProduction Agencies assist in the tests. It is also noted that the Regional Director of OSHAindicated that OSHA regulations applied only in bulk quantities.

18 October through 6 June 1974 (Ref. 318)Interoffice Memos and TWX Messages: MOCA in Urine Monitoring Program,Use ofAlternative AdhesivesLine 1

A list of employee badge numbers and work areas are included in an October interoffice memowhere urine analysis for MOCA is under 0.04 mg/l for all employees. The work areas for theseemployees consist of Buildings 1-12, 1-53, and 1-61. A January interoffice memo contained asimilar list of urine analysis. On employee tested from Building 1-53 contained 0.06 mg/l ofMOCA in his/her urine, but a February urine analysis of the same employee contained under0.04 mg/l of MOCA. A urine analysis reported in March listed two employees with 0.10 and0.12 mg/l ofMOCA in their urine. Both employees worked in Building 1-12. An Aprilinteroffice memo listed four employees from Buildings 1-12 and 1-61 with urine analysesindicating anywhere from 0.04 mg/l to 0.61 mg/l of MOCA in their urine. Urine analysis ofemployees in May indicated three employees with MOCA concentrations ranging from 1.10 mg/lto 1.80 mg/l in their urine. These employees worked in Buildings 1-61 and 1-53. One listedemployee, assuming that badge numbers were not dynamic, tested for MOCA in April and had aconcentration under 0.04 mg/l, but jumped to 1.80 mg/l by early May.



Recorded outgoing communication messages list alternate adhesives for MOCA. Manyoperations or components using MOCA were replaced with these alternative polymers; however,cover bonding still required the use ofAdiprenelMOCA in the W69 Program.

The W71 program no longer required the use ofMOCA, but the W68 Program still required theuse of WS 12391, which contains MOCA , for certain operations. The need for this adhesive ispending. A later recorded message reported that the W68 program glove box operation in theassembly area was to be deleted which would eliminate five major handling operations, improvethe quality of the pre-mixed sealant application, and decrease assembly time by four man-hoursper unit.

6 February 1974 (Ref. 312)Letter: Permanent Standards for MOCADu Pont

This Du Pont letter pertains to the permanent standards published in the Federal Register byOSHA. The requirements are similar to those of the emergency temporary standards, however,full air suits are no longer specified and continuous air supplied hoods and impervious garmentsneed only be worn for certain operations. The permanent standard does not apply to mixturescontaining less than 1 percent MOCA. Open vessel operations must be conducted under a hoodwith good ventilation, and the operator must wear a filter-type respirator. Exhaust air must bedecontaminated before discharge to the external environment. In addition, permits are notrequired to use MOCA.

As a result of the permanent standards, which are attached to the letter, it is reported that theproduction and sale ofMOCA will continue in a normal fashion. Labels on MOCA containerswill include the warning words "Cancer-Suspect Agent".

14 June through 25 July 1974 (Ref. 319)MOCA Swipe Sample AnalysisLine 1

An interoffice memo dated June 14, 1974, reports that swipe sample results collected from aglove box located at Building 1-10, Bay R contained 49.0 micrograms per 24 square inches ofMOCA contamination. These results were phoned to the Line 1 Safety Office. Two samplesreceived by the Safety Department were obtained following the clean up of Building 1-53. In aletter dated June 20, 1973, the results ranged from 18.8 to 25.0 micrograms per square yard.Samples taken from the SW comer table in Bay B of Building 1-53 indicated 107.5 microgramsper square meter. Thirteen swipe samples were obtained in Buildings 1-40, 1-53, and 1-11,mixing station 1-19-7 and ovens in 1-19.

The MOCA concentrations ranged from 0.0 mg/l per square yard to 1235.5 mg/l per square yardin the SW wall and table in Building 1-53, Bay B. The Safety Department ofMason & Hangeranalyzed these.

Additional swipe samples obtained July 5, 1973, from Building 1-53, Bay B and C, indicatedMOCA concentrations ranging from 10 mg/l to 550.0 mg/l per square yard. Swipe samplesreceived by the Safety Department on July 24, also from Building 1-53, Bay C contain20.0 micrograms/square yard to 1,562.5 micrograms/square foot.

rl,



hydrocarbons and carbon monoxide emitted by IAAAP workers driving to and from work ishigher than that emitted by burning nearly 7,600 lbs. of TNT per day. However, TNT emittedmore NOx, soot, and ash than the automotive pollution caused by IAAAP employees.

Building 1-62 was converted from a coal fired steam plant to a natural gas plant in December1969 greatly reducing the effluent released from the smokestacks. This comparison summary isincluded in the document as well. A comparison between ammunition procurement and supplyagency maximum limits in water and the effluent from Brush Creek at the installation's southernboundary show that the contamination in Brush Creek is below MCLs except for Nitrate andPhosphate.

21 December 1971 (Ref. 368)Letter: Iowa Air PollutionIAAAP & Burlington AEC Plant

The site has two potential sources of air pollution, the steam plants for the Army and the burningfield for the AEC. The letter discusses the two separate and distinct agencies ofthe IAAAP andthe Burlington AEC Plant. Mason & Hanger have two contracts to operate all the facilities atthis site.

This letter is from the Burlington Area Office Manager to the Iowa Air Pollution ControlCommission to request that the AEC assume liaison with the State of Iowa relative to thoseatmospheric environmental matters connected with the AEC's burning field. In the past, theArmy has maintained liaison for all atmospheric environmental matters relative to thisgovernment-owned site. The AEC also requests a variance to bum HE so that it may otherwisecooperate with the State in environmental matters.

21 March 1972 (Ref. 377)Letter: Waste Explosives DisposalBurlington AEC Plant

This letter is from the Iowa Air Pollution Control Commission to the Burlington Area Managerregarding the progress of an incinerator. The Burlington Area Office submitted contradictorystatements about the phase in which the incinerator was presently in, conceptual design orcompleted construction.

9 April 1972 (Ref. 378)Letter: Iowa Pollution Control CommissionBurlington AEC Plant

This letter references the March 21, 1972, letter pertaining to waste explosives disposal andconfusion over incinerators at the Plant. It is reported that the prototype incinerator referred tothe letter of January 6 is for the purpose ofdisposing of scrap propellant and contaminatedpropellant powder. An additional Army incinerator project is in operation using an adapteddestruction furnace. This project is for the purpose of collecting emission data as opposed toeliminating any environmentally unsuitable material emanating from expensive destruction. It isnoted that the intent ofthe AEC is to utilize all ofthe existing and programmed work in the fieldto establish environmentally suitable destruction methods.



4 April 1972 (Ref. 63)Letter: Phase II Report, Radioactive Effluent ReductionFiring Site

This letter includes the completed Phase II Report. The source of release noted in the attachmentis hydrodynamic explosives test fire shots, which release U238 into the air by high explosivesdetonation. The proposed control measures are total containment of detonation products, ventedstructure partial containment, atomized water spray-scrubber action, blasting mat-fragmentretention, and barricade modification fragment retention. The reduction of effluent for eachproposed control measure is noted ranging from 99.3 to 5 percent, respectively. Therecommended control choice is total containment of detonation products at a cost of840,000 dollars with 99.3 percent reduction of quantities of radioactivity discharged to thelowest practicable levels.

6 April 1972 (Ref. 379)TWX Message: Access to Army ResultsBurlington AEC Plant

The TWX message confirms a telephone conversation from the Burlington AEC Plant Managerto the Assistant Manager of the Office of Plans and Budgets in Albuquerque. Mason & Hangerare having difficulty obtaining access to Army development program results for environmentallyacceptable methods of explosive disposal. It is required that someone in ALO or Washington,DC, contact the Army to request copies coverage of their development program documents andto establish a contact for Mason & Hanger in which to communicate.


Attached to this letter (a response to requested information) is a form, which indicates two typesofmaterial released. It is reported that D-38 is released by a destructive test procedure requiredby the Design Agency. A sum of 200,000 dollars will be budgeted for FY74 for a containmentvessel. The second item, Tritium, is released during checking of the atmosphere around materialin sealed containers. At the present (1972) no control measures are anticipated.

11 August 1972 (Ref. 388)Letter: Compliance with State and Local Requirements with Respect to the Control andAbatement of Air POllutionBurlington AEC Plant

The subject of this memorandum is the AEC's consistent policy that AEC facilities are notsubject to state and local regulations per se, which includes the various permit applicationrequirements. It is stated that while this is true, environmental protection and enhancement is anestablished policy of the federal Government, which is fully supported by the AEC. All AECfacilities are presently required to meet all state and local air quality standards includingemission standards adopted pursuant to the Clean Air Act. It is the AEC's interpretation that theword 'requirements' used in Section 118 of the Clean Air Act, as applied to state and localgovernments, actually means 'standards'.

The letter reports that the AEC facilities do cooperate with state and local pollution controlagencies, in preventing and controlling pollution of the air as a matter of comity. However, this

2.4.2.6 Holding/Settling Ponds for Industrial Waste Water

January 1980 (Ref. 141)U. S. Army Toxic and Hazardous Materials Agency Installation Assessment of IAAAP

Contaminated water from facility operations is currently treated with settling tanks and granularactivated carbon prior to discharge to surface water. Treatment facilities are present inBuildings 1-40, 1-70-1, and 1-70-2.



Waste water at Line 1 is transferred to the treatment tanks through a system of4-in.-diameterpolypropylene pipe connected directly to the laboratory sinks. The transfer of liquid isaccomplished by gravity feed (EBASCO 1989). This waste water from explosives loadingoperations is then treated by carbon adsorption in adjacent filter houses, and the effluent isdischarged to drainage ditches (gullies) that flow to NPDES-permitted outfalls to Brush Creek.The two melt buildings have historically generated the highest volumes of waste water at Line 1.

A review ofhistorical records indicated a formerly active (when Line 1 is activated and beingused) settling impoundment onsite. The impoundment was reportedly created at Line 1 bydamming up Brush Creek (U.S. Army Toxic and Hazardous Materials Agency, 1980).

Holding/settling ponds include the Line 1 settling pond (formerly active) used by AEC. A pondwas created at Line 1 by damming up Brush Creek. Explosive wastes including TNT,composition B, cyclotol, PBX, barium, and other materials were discharged to thisimpoundment. Analyses ofwater samples taken immediately below the dam in 1952 showedTNT concentrations as high as 114.6 ppm. The dam was later removed and the impounded areawas cleaned out.

25 February 1982 (Refs. 205 and 206)SCS Engineers Subsurface Investigation at Site ZI (Abandoned Pink Water Lagoon) IowaArmy Ammunition Plant

The purpose of this investigation was to obtain information on the Pink Water Lagoon at Line 1to help IAAAP come under compliance with the regulations of RCRA and the Iowa Departmentof Environmental Quality.

The report explains that the previous Line 1 impoundment dam was built approximately 200 ftnorth of the intersection of Brush Creek and D-Road. The Pink Water Lagoon was in use from1948 to 1957. The dam impounded approximately 3.6 acres and extended 1300 ft upstream.After storm events or during periods of high stream flow, the area covered by the impoundmentwould have been approximately 7.5 acres extending 2400 ft upstream.

According to this document, Line 1 effluent originally was discharged to the stream and lagoonby overland flow and through a number of small ditches. Later, several small settling basinswere installed upgradient of the Pink Water Lagoon. A portion, ifnot all, of the Line 1 dischargepassed through these basins prior to entering the lagoon.

The sediments that were deposited during the use of the lagoon were dark brown to black sandysilt to black sandy clayey silt containing coal fragments. The sediments are dark brown to blackbecause of the intermittent addition offly ash to absorb explosive components and reduce the redcolor of the water. These sediments can be distinguished from the natural soils below, whichwere lighter in color, from brown to gray with sandy silty clay textures.

21 July 1989 (Document # 437)Dames & Moore Endangerment Assessment Iowa Army Ammunition Plant: Former Line 1Impoundment and Line 800 Pink Water Lagoon Draft Final Report for USATHAMA

The purpose of this assessment was to determine potential present and future public health andenvironmental risks and to identify preliminary remedial action criteria corresponding to cancerrisk levels at Line 1 and the Line 800 Pink Water Lagoon.



The Dames & Moore (1989) study included soil and sediment sampling. Explosives detected insoils were cyclonite (RDX), cyclotetramethylene-tetranitramine (HMX), tetryl, 1,3-DNB,2,4-DNT, 2,6-DNT, 1,3,5-TNB, and 2,4,6-TNT. The dominant explosives detected in soils wereRDX and HMX at concentrations up to 400 mg!kg and 61 mg!kg, respectively.

Generally, detectable explosives were only present in soil samples from depths of I to 2 ft.Contamination was found in the Brush Creek streambed, frequently up to 4 ft in depth. Bariumwas the only metal found at elevated levels (up to 903 mg!kg).

Other investigations conducted at the site are summarized below:

• 1982, ERG Contamination Survey: The purpose of this study was to conduct initialmonitoring at the Line 800 Pink Water Lagoon and additional monitoring at the Line 1Impoundment. This survey determined that discharge of contaminated groundwaterassociated with the former Line 1 Impoundment or sediments from the former Line 1Impoundment was a potential source ofRDX contamination to Brush Creek.

• 1984, Battelle Follow-On Study of Environmental Contamination: This study consistedof additional hydrogeologic investigations of the former Line 1 Impoundment and Line 800Pink Water Lagoon.

• 1985, AEHA Investigation of Groundwater Contamination: This document was preparedin response to a congressional inquiry concerning potential contamination of an offsitedomestic drinking water well.

• 1986, Dames & Moore, Midwest Site Confirmatory Survey: During this survey, surfacewater and groundwater samples were collected around the former Line 1 Impoundment andLine 800 Pink Water Lagoon.

• Dames & Moore, Remedial Actions Assessment (unpublished): The overall objective ofthis remedial actions assessment was to collect and analyze the data necessary to plan,evaluate, and develop remedial actions for the Former Line 1 Impoundment and the Line 800Pink Water Lagoon.

Samples were collected to determine the extent of contamination at the Line 1 Impoundment.The samples were collected at 0-2 ft bgs at 1410cations and at 10 ft bgs at 410cations.

Explosives detected in soils included RDX and HMX at concentrations up to 400 mg!kg and61 mg!kg, respectively. The highest concentrations of RDX past and present (1987) wereobserved in the Brush Creek Valley, extending for a distance of approximately 1000 ft alongBrush Creek.

The contaminants of concern for soils/sediment were identified as RDX; HMX; tetryl;1,3-DNB; 2,4-DNT; 2,6-DNT; 1,3,5-TNB; 2,4,6-TNT; and the metal barium.

D-38 in hydro shots lost approximately 590 Ibs. (17 percent) as contamination in the demolitionfield. The area contaminated has a radius of roughly 1,000 feet. Some D-38 is burned, but nonewas detected outside the firing site. Recovered contaminated material is sent to the Pantexunderground burial pit.

Beryllium is reported to be present in sanding operations, yet swipe sampling and urinalysis ofoperators is performed to monitor this contamination. Chromate 0.05 spec routine analysis issometimes high and needs work. Chromate contaminate is recycled periodically in Brush Creekfrom the closed heat exchange unit in Line 2. About 8 to 16 Ibs. of Chromate per week are lostfrom these systems and go into Brush Creek.

Mercury fumes are present, but below TLV values as determined by atomic absorption unit.Nitrates are in water are high when there is less than normal rainfall. Phosphates are always highand silver is sometimes high due to overflow from the silver reclaimers in conjunction withX-ray film processors.

Division A

List ofhigh explosives in each line is given including: Line 2 - TNT, Octol, Compo B, Line 3ATNT, Compo B, Line 4B - Shilla, Line 5A - TNT, Line 5B - Tetryl, Line 6 - Lead azide,tetracene, lead styphnate, Line 7 - Black powder. 12,000 gallons ofRE sump water is removedto the leaching field each day. Line 3A utilizes a filter system to furnish TNT-free water forwashdown. TNT that enters Brush Creek from other operations is removed by the addition ofFly Ash from the power plant to the creek, which subsequently raises the ph of the water slightly.

General Summary (Division A & B)

Lists chromate facts. Reports the start of the inert disposal operations in September of 1969 withthe land fill. Two-hundred cubic yards per day is the average disposal entered into the land fill.The Powerhouse converted to natural gas in December of 1969 reducing the S02 considerably.The chemical disposal pit is described by its properties (i.e. lining, etc), reporting the disposal ofapproximately 20 gallon pesticides per year and 700 gallons of herbicides each year. The TNT(red water) AEC system is functioning well with 3 units having a capacity for 200 gallons perminute using settling tanks, earth filters, and carbon filters. The Army Red Water uses aleaching bed which has problems in the winter.

The radioactive wastes are sent to the burial ground. Residue left from burning the radioactivecontaminated explosives and hydro shots is reported with hydro shots loosing 50-60 Ibs. per shot(57 shots). A total of7,064 1bs. of waste has been sent to Pantex since October 1969 (February1971 report) along with a small amount ofPu239 . The installation of background air and soilsampling for plutonium is going to start.

HE disposal exists for both Division A & B. The AEC bums approximately 1300 Ibs. ofexplosives per day for the Army using dunnage and fuel oil with igniter. Metal materialscontaminated with explosives are flashed in field. A small quantity ofD-38 contaminatedexplosives is burned, approximately 6,000 grams in the next two years.

1 March 1971 (Ref. 352)Letter: Release of Radioactive Effluents from ALO FacilitiesBurlington AEC Plant

This letter includes a list of the radioactive effluents and/or releases at the plant. Approximately0.006 curies of Tritium is released to the environment. Depleted uranium D-38, dispersesapproximately 22 kg per hydro shot into the environment with a total of 57 shots jired by thetime the letter was drafted. Approximately 2,000 grams ofD-38 with high explosives is burnedat the explosive disposal field per year. The amount dispersed to the environment is unknown,but residue on the burning pad is recovered and sent to the burial ground.

Approximately 7,000 lbs. per day of high explosive solid wastes generated are destroyed byburning at the explosive disposal field. HE contaminated effluent water no longer poses aproblem due to the installation of settling and filtration systems. A sanitary land fill operationfor all garbage and non-contaminated combustible trash has been in operation since September1969. Due to the sampling and analysis of effluent streams, all contaminants are withinacceptable limits except for Chromates (from the cooling towers).

Two sewage treatment plants are within IAAAP. The main plant (Brush Creek SewageTreatment Plant), located between Line 2 and Yard E, has a capacity of2,838,750 liters per day.This plant serves all areas except Line 3A. The treatment facilities at this plant consist of anImhofftank followed by a trickling filter and final settling tank. Sludge from the drying beds isplaced in the sanitary landfill while the effluent is discharge into Brush Creek. The second plantis just southwest of Line 3A. This plant is designed to service Line 3A because the line is soremote from the main collection system. The treatment process is similar to that of the mainplant, with the effluent being discharged into Skunk River. The sewage treatment plants are notbelieved to contribute to any off installation migration of contaminants. Line 1 sanitary waste isreleased to the main sewage treatment plant.

There are above-ground storage tanks located at Line 1. In the vicinity of the PowerPlant/Heating/Air-Conditioning Plant, Building, there are six large tanks for the storage of fueloil. Each of these tanks has a capacity of 126,000 gallons. In addition, there is an LP GasStorage Tank of 116 gallons at the Heating Plant. Research has shown no below-ground(underground) storage tanks located at Line 1.

1954 (Ref.lS7)Project History of Line 1 Operations at Iowa Ordnance Plant January 1 1947 - July 1, 1954

There is a possibility, however, that there may have been underground storage tanks located atBuilding 1-129 where a new vehicle repair facility was constructed, along with a filling station.

2.4.2.10 Health and Protection Surveys

Health Protection Appraisal Reports: These reports appeared to be have done on a yearlybasis for the section of the Plant that was under AEC's control. But, other common areas weresometimes visited and commented on. A review of the microfilm files shows that the initialHealth Protection Appraisal Visit occurred in November 1967 and the last one documented wasin March 1974.


Work Plan for Supplemental Remedial Investigationfor Line I (Including Historical Site Assessment) - IAAAP

November 1967 (Ref. 123)Health Protection Appraisal Report, Burlington AEC Plant, Burlington, Iowa,November 14-16, 1967

The summary of the survey stated that the Burlington AEC Plant is providing a comprehensivehealth protection program for its employees and is controlling waste discharges in such a mannerthat water and air resources are not being significantly degraded.

Radiological and other toxicological exposures are being maintained at acceptable levels andmeet AEC standards. The industrial medical program, although understaffed, is comprehensiveand offering relatively complete services.

Liquid sanitary and industrial wastes are adequately processed prior to environmental discharge.No significant pollution arises from AEC activities. HE wastes are at present being adequatelytreated by filtration and activated carbon adsorption. Pollution of Brush Creek is being abated.

In the "Discussion & Conclusions" part of the report, the following information was written.Radiological hazards are controlled by surveys of the internal and external exposure potentials totritium, plutonium, uranium and the proper operation of industrial X-ray and cobalt 60radiographic sources. Area monitors are located in places where radiation may be a problem andpersonal dosimeters are worn by those workers potentially exposed to radiation hazards.Operating procedures are written, approved by management, enforced by inspection, andreviewed at adequate intervals to assure compliance with AEC MC 0504 guides.

Exposure to toxic chemicals is controlled by administrative, engineering, and educationaltechniques. Liquid industrial wastes are adequately treated and pollution abatement of BrushCreek is being achieved. It was suggested that chromium and sulfite analysis be performed onwaste water from the boiler plant.

In "Findings," five inspectors are assigned to identify, evaluate and control toxic hazards, theadequacy ofheating and ventilation, noise control and the provision of adequate sanitaryconveniences. Toxic hazards consist of exposure to TNT dust, TDI in plastic potting and anarray of solvents or cleaning compounds from acetone to trichloroethylene.

Protective techniques include issue of coveralls, gloves, and respiratory devices when indicated,provision of exhaust ventilation, and insistence on personal hygiene. Spray painting is done inwaterfall booths, and when appropriate, painters are provided air supplied respirators. Whenchemicals which may cause skin irritation are used, lavatories supplied with soap are locatednearby. Besides gloves, barrier hand creams are used to control dermatitis. Chemical fumehoods are designed to provide air velocities of 100-150 lfrn at the hood face. Hood air velocitiesare checked at semi-annual intervals or whenever production processes change.

Potential radiological hazards to which workers may be exposed are tritium, plutonium anduranium and the use of X-ray generating devices for nondestructive testing. All pressurized canswhich may be potentially contaminated with radioactivity are checked to assure integrity of theircontents. A T-289 instrument is used to check for contamination of the inert gas as it is releasedto the outside atmosphere under exhaust ventilation from the shipping containers. Whennecessary, containers are purged so that residual radioactivity is less than 90 uci/m3. Continuousair monitors designed with both visual and audible alarms are installed adjacent to the workspaces. Twenty-three air monitors are mounted throughout the plant is strategic locations. Theyare checked every two weeks to determine that they are in working effectively. Ten day, 24-hour



reading charts are also maintained in those areas where radioactive gases are employed. Allradiation detection instruments are routinely tested and calibrated; alpha meters are calibratedmonthly and g~ma detectors are calibrated quarterly.

Personnel exposure to ionizing radiation is well below AEC standards. Sixty-five persons arenormally badged. Results from January 1 to date indicate from zero to a maximum of320 mraccumulated dose by one person. Seven neutron badges are assigned to selected workers. Noperson has a significant exposure to tritium as reflected by urinalysis. Floors and workbenchesofproduction and storage areas are routinely surveyed to assure contamination control. Recordsindicate that contamination is controlled.

No liquid radioactive wastes are normally produced. One 55-gallon drum per year ofHEcontaminated solid waste in the form ofU238 powder absorbed on Kimwipes and in vacuumfilter collector bags is generated. These low level wastes are burned at the HE disposal pads.Plutonium contaminated wastes, on the other hand, are stored in plastic bags in a 55 gallonshipping container. They will be shipped to an approved radiological disposal burial groundwhen necessary. In eight years, less than one drum of these wastes has been accumulated.Through agreement, between the Army and the AEC, the AEC is responsible for operating theHE disposal operations. These wastes are handled by the AEC in an approved manner.

TNT liquid wastes are presently being adequately processed at Buildings 1-40 and 1-70 wherethe following sedimentation in two settling tanks, operated in parallel, suspended solids areremoved by passage through Celite coated Sparkler leafpressure filters. Solids accumulated inthe settling tanks are removed by shoveling and are packaged in plastic lined 5-gallon cans.Together with the Celite coated filter residue, these wastes are transported to the HE burninggrounds for incineration with dlfnnage. Effluent from the filters containing an average of70-100 ppm of soluble TNT, is then fed to four parallel activated carbon adsorption columnswhere the TNT concentration is reduced to less than 5 ppm. The treatment facility has beendesigned to process up to 15,000 gallons per day. When TNT levels approach 5 ppm, one andone-half feet of spent carbon is removed from the absorption column and replaced by freshcarbon. Effluents are therefore free of solids and the soluble TNT fraction is below that levelcapable of causing red water is brush creek.

Note: Through the historical investigation performed by TN&A, TN&A has not been able toconfirm nor refute the implication that radioactive liquid wastes MAY have been produced.

January 1969 (Ref. 127)Health Protection Appraisal Report, Burlington AEC Plant - Burlington, Iowa,January 21-23,1969

This report closely agrees with the previously reviewed report. Some of the changes in thisreport, compared to the previous one, include: A draft ofAECM 0544 "EmergencyPreparedness for Accidents Involving Release of Radioactivity" will require that contractorsestablish formal written agreements with local hospitals to care for radioactively contaminatedinjured persons, therefore, the contractor will be required to arrange for these services.

A recent staff acquisition now enables the medical staff to provide onsite psychological serviceand counseling for plant personnel with emotional problems.

In compliance with AECM 0545 appropriate personnel have been assigned Savannah River typecriticality dosimeters in the form ofpocket clips. Readout capabilities are capable on site. The



film badge service being used requires that the film badges be sent off-site for processing andreading. Emergency Response teams consist of Safety Department health physics monitors andproduction personnel competent in explosive ordnance and demolition. Supplies of protectiveclothing, respiratory devices and other field equipment are maintained in portable containers foremergency use. Dosimeters are not stored in the emergency supplies but would be taken fromregular use if the teams were to be activated. Ten team members received one week ofemergency response training at the Nuclear Training Directorate, DASA (Defense AtomicSupport Agency) during September and October of 1968.

All other information in this report is almost identical to what was in the report of November 1416, 1967.

September 1969 (Ref. 127)Health Protection Appraisal Report, Burlington AEC Plant, September 17-19, 1969

This report was considered to be an Interim Health Protection Survey by AEC AlbuquerqueOperations Office (AOO).

A recommendation is this report is that a hand monitoring program be established for employeeswho may handle or work in close proximity to certain radioactive components during assemblyor disassembly operations.

In the "Discussions and Conclusions" section of the report, it was stated: Personnel exposure towhole body, penetrating radiation is well controlled and records show that such exposure hasbeen far below AEC guides. There has been no contamination incident, high air sample, orsurvey data that would result in potential for internal personnel exposure to ionizing radiation.

Hand exposure studies have been made in the past, with results that indicate only nominalexposure. However, no hand monitoring has been done with the past year. With the new itemsthat are coming into production, and the strong possibility of reduced exposure guide forextremities a program of hand monitoring is now in order. Finger or wrist dosimetry should beprovided for those employees who work directly with radioactive units that have significantsurface dose rates. It is suggested that the use of thermoluminescent dosimetry (TLD) beconsidered for this purpose.

A program of hydrodynamic tests, or hydro shots, has been started at Firing Site FS-12. Eachshot involves the expenditure of many pounds of HE and a few kilograms ofuranium-238.During the course of the program, a large amount of uranium will be dispersed to theenvironment. Exact quantities and configurations are classified. Hydro shots have been made atPantex, Los Alamos and LRL with no apparent problems. The specific activity of uranium 238is quite low, and if widely dispersed, it is difficult to detect with standard radiation monitoringequipment. However, a series of hydro shots that involves the quantity of uranium now plannedfor FS-12 may contribute measurable contamination to the environment. Both BRAO(Burlington AEC Plant) and M&H-SM Co. (Mason & Hanger-Silas Mason Co) management arecognizant of the above, and the program was undertaken only because it is a Quality Assurance(QA) requirement ofLRL. Design engineers state that no other metal may be substituted foruranIUm.

A comprehensive monitoring program has been started at FS-12 and will be continued as theshots occur. Documentation of monitoring results is essential, and plans presented to M&H-SMCo. safety personnel appear to be appropriate.



Six hydro shots have been fired at FS-12 to date and when the program is fully implementedabout one shot per week may be expected. At each shot, a few pounds of uranium 238 isconverted into a fine oxide powder and dispersed to the atmosphere

by the explosion. The larger particles fall out near the firing site and the very small pieces ofuranium metal are also found at the firing site. On some shots, larger pieces of uranium metalare also found at the firing site. Direct surveys have been made, none have exceeded normalbackground. The monitoring program will continue and results recorded. These records will bereviewed during future appraisal surveys.

Disposal of liquid waste containing TNT has been a problem of long standing. It now appearsthat this problem has been solved for Division b, the AEC Plant. The new filter systems andfunctioning very efficiently. With few exceptions, discharges to Brush Creek will averagebelow 5 ppm of TNT, and samples from the stream are normally less than one ppm. However,the Army has not yet converted their disposal system, for Division A to the activated charcoalfilters. Any high contamination of Brush Creek can now be attributed to Division A.

March 1972 (Ref. 126)Health Protection Survey, Mason & Hanger-Silas Mason Co., Inc., Burlington AEC Plant,March 14-17, 1972

Under the heading of "Findings and Recommendations" Operating procedures pertaining toradiation safety are not reviewed annually.

The contractor does not have a formal procedure to assure, through analyses, adequate quality ofbottled or line-supplied breathing air.

Automatic conductivity measurement and control systems have not been provided for all coolingtowers to control loss of chromate with the subsequent pollution of effluent water courses withchromate ions.

The medical department has not conducted biological calibration tests on the audiometer.

Under the heading "Discussion," the following information is provided:

The contractor generally reviews radiation safety procedures when a change in a procedure isproposed. The proposed change carries a transmittal page on which is provided a concurrenceladder, including review and sign-off by Area Office personnel. Proposed new procedures carrythe same transmittal sheet with the concurrence iadder. However, the contractor has no formalmechanism to assure annual review of the radiation safety procedures as required byAlbuquerque Operations Office (ALO) 0504-037(a). A statement requiring annual reviewshould be added to the Component Parts Manual or similar document.

Breathing air is supplied by the plant fire department. A Cornelius three-stage compressor isused to provide the compressed air for Scott Air Paks (sic) and air-line supplied breathing air.Although, the contractor now periodically checks breathing air quality, a formal procedure toassure breathing air quality should be prepared and published. The procedure for air qualityshould also include an assurance that breathing air line couplings are not compatible with othergas line outlets throughout the plant. These requirements are detailed in Section 1910.134 of theOccupational Safety and Health Act Standards of 1970.

Work Plan for Supplemental Remedial Investigation for Line I (Including Historical Site Assessment) -lAAAP

By letter to the Contracting Officer, Burlington AEC Plant, dated March 1, 1971, the contractoroutlines his pollution control program. One item in the program noted that "chromate levels aresomewhat high due to the loss of chromates from the cooling towers'. It was proposed thatautomatic systems to measure water conductivity and to add chromates only as required, wouldbe installed. It was anticipated that such systems would reduce the loss of chromate and thusreduce the level of chromate ion contamination of effluent streams. To date, one automaticsystem has been installed in a cooling tower, with three proposed systems yet to be completed.Since the blowdown of cooling towers is the source of chromate ion contamination of effluentstreams, it is imperative that the proposed systems be installed as soon as possible.

The medical department sends the audiometer units to the manufacturer for calibration andmaintenance as the needs arise. However, "biological calibration" on a routine basis has notbeen performed. OSHA (National Safety News, January 1972) requires "biological calibration:checks at least every two weeks. Records of the calibration checks are to be maintained forreview and inspection.

25 May 1973 (Ref. 410)U.S. Atomic Energy Commission, Burlington Area Office Letter, to Mason & Hanger-SilasMason Co., Inc., AEC Plant Manager. Subject BRAO Safety Survey 73-8, dated May 25,1973

The enclosed subject survey is transmitted for review and action. There are planned visits fromboth the Iowa Quality Department and the Environmental Protection Agency scheduled for Julyor August. Letter requests that action be taken on the two recommendations by June 15, 1973.

Summary of the three items: The newly enacted Federal Water Pollution Control ActAmendments of 1972 mandate a sweeping Federal-State campaign to prevent, reduce andeliminate water pollution. Spring Creek flows through the AEC burning grounds and directlyinto the Mississippi River. Combined with the existing air pollution problems associated withopen burning of HE, any water pollution of Spring Creek from HE disposal operations couldhave a serious impact with the EPA and the State ofIowa Department ofEnvironmental Quality.

As noted in a memorandum from Jack Roeder dated April 23, 1973, the present HEdecontamination facility in the burning ground is inadequate. HE contamination is washed fromtrucks and a variety of containers on an open cement pad. On two separate occasions, visualevidence indicated large amounts of rinse water contaminated with large amounts of rinse watercontaminated with explosives and copper sulfate had drained around the small catch tank anddown into Spring Creek. The proposed construction of a holding tank for the waste water willeliminate this problem.

Solid waste material generated from HE disposal operations is presently being deposited in threelarge ash piles which run along the west bank of Spring Creek and into the Spring Creekwatershed. This solid waste consists of ash from the HE burning pads, metal trash from flashingoperations, and the ash from burning HE contaminated materials. Contamination of SpringCreek by runoffs from the solid waste piles is quite probable during periods of rainfall. This factwas also identified in a U.S. Army Water Quality Engineering Survey conducted in September1971.

Ill-I



A landfill operation north or west of the Spring Creek watershed appears to be a simple, feasiblealternative for solid waste disposal. A landfill would eliminate any potential of water pollutionand would greatly improve the appearance of the AEC burning ground.

On the second item, the findings were that wash water from HE decontamination ofvehicles andcontainers is draining into and polluting Spring Creek. Recommendations: Construction of theproposed wash building is expedited.

The third finding was that contamination of Spring Creek by runoffs from solid waste deposits ispossible during periods of rainfall. The letter's recommendation is an engineering study isconducted to determine the feasibility, location, and established cost of landfill operation for theburning grounds. This study should also consider a clean-up operation of the present solid wastedeposits.

This document is a magazine article on the DARCOM project about the identification andevaluation ofhistoric structures on 74 bases. The evaluation will include the study ofarcheological resources.

Date Unknown (Ref. 301)Magazine/Newspaper Story"Army, Park Service Survey History at 74 Sites"

This article reports on the project to study 74 Army installations and sub-installations, manydating from WWII as ammunition and storage depots, under contract with the Army MaterialDevelopment Command (DARCOM). This study is a part of the Historic American BuildingSurvey/Historic American Engineering Record, and the Interagency Archeological Services(lAS).

August 1984 (Ref. 247)Historic Properties Report (National Park Service)Iowa Army Ammunition Plant

This document consists of the final historic property report of the Iowa Army Ammunition Plant.Constructed in 1941, the plant occupies 19,124 acres in Des Moines County in southeasternIowa. Initially, the plant loaded, assembled and packed bombs, mines, and artillery shells, aswell as constituent boosters, detonators, fuses, and primers. Placed in standby condition afterV-J Day, the plant reactivated for Korean War production and remains in production to present.The original WWII technology was replaced during the 1960s and 1970s. Current production (in1984) included loading, assembling, and packing large-caliber artillery projectiles, missilewarheads, and explosive-train components. ThelAAAP also operated an atomic-bombproduction complex during the late 1940s and 1950s. This facility ceased operation in 1975.

Originally, the manufacturing area consisted of eleven separate complexes: two for loading,assembling, and packing artillery shells (Line 1, 2), one for bombs (Line 3), two for fuses (Line4A, 4B), two for boosters (Line 5A, 5B), one for detonators (Line 6), two for primers (Line 7, 9),and one for producing crystallized ammonium nitrate (Line8). An additional bomb loading linewas erected in February 1942 (Line 3A). In 1947, a highly classified production complex wasbuilt at Line 1 for the newly established AEC. As late as 1970, a technological study of theplants reported outdated equipment, congestion of facilities, capacity limitations, low efficiency,and manual operations, which were potentially hazardous to personne1. To remedy thesedeficiencies, IAAAP embarked on a major modernization program that resulted in the completerebuilding of Line 4A and 4B, and the retooling of most other production facilities.



2.4.2.14 Other Historical Environmental Investigation Documents

January 1980 (Ref. 141)U. S. Army Toxic and Hazardous Materials Agency Installation Assessment of lAAAP

This document reports that loading operations began on Line 1 in September 1941. Line 1terminated production on August 14, 1945. This document also reports that the U. S. AtomicEnergy Commission took over and operated the Line 1 facility from 1947 to July 1, 1975.

The Installation Report gave a brief history of contamination history at Line 1. Between 1949 and1955, waste water from Line 1 was discharged into Brush Creek, and contamination was detecteddownstream. A dam was then placed to prevent the downstream contamination. After the damwas removed, explosive contamination including TNT, Composition B, cyclotol, PBX, and bariumwere found in the sediments bordering Brush Creek at the previous impoundment location.

This report concluded that Line 1 was a contaminated area, and further investigation would beneeded to fully identify the areas of contamination.

21 September 1990 (Ref. 444)Federal Facility Agreement under CERCLA, Section 120

The general purpose of this agreement was to ensure that the environmental impacts associatedwith past and present activities at the site were thoroughly investigated and appropriate remedialaction is taken as necessary to protect public health and welfare and the environment. Only ageneral description of Line 1 was included in the document.

8 May 1991 (Ref. 443)Community Relations Plan for the Iowa Army Ammunition Plant

This report was prepared to determine the level of community concern and interest in theInstallation Restoration Program at IAAAP. There is no specific or pertinent information in thisdocument about Line 1.

August 1991 (Ref. 198)JAYCOR Preliminary Assessments for the Iowa Army Ammunition Plant

This study was conducted to identify areas ofpotential contamination at lAAAP. This documentpresents a brief summary of areas of concern at Line 1. There were 22 buildings used forexplosives processing. Two melt buildings (Buildings 1-05-1 and 1-05-2) produced the highestvolumes of explosive waste from the washing down of floors and equipment in the buildings.The effluent was treated by carbon filtration in filter houses (1-70-1 and 1-70-2) and dischargedinto drainage ditches. Before the installation of a carbon filtration system, the pink watereffluent was discharged into the drainage ditches leading to Brush Creek.

This assessment found that wastes other than explosives were generated at Line 1. Some of thesewastes were solvents such as acetone, total xylenes, 1,1 ,I-trichloroethane, and Stoddard'ssolvent. The metal chromium was also identified.

June 1992 (Ref. 445)JAYCORlCDM Phase I Remedial InvestigationlFeasibility Study Final Work Plan for theIowa Army Ammunition Plant

This document outlined work to determine the nature and extent of contamination at IAAAP.



21 May 1996 (Refs. 264 - 274)JAYCOR Remedial InvestigationlRisk Assessment Revised Draft Final for the Iowa ArmyAmmunition Plant

This document reported details of the Phases I and II sampling analysis programs and a followon RI conducted at IAAAP from July 1992 through June 1995. A description of the meltbuildings (Buildings 1-05-1 and 1-05-2) was included in this report along with information abouta spill in the basement of the melt building (Building 1-05-1) in June 1992. A pipe leading to anopen trough carrying washdown water became clogged, and an unknown amount of pink waterflooded the basement.

The highest concentrations of explosives detected during the RI/RA were around Buildings 1-40(ammonium nitrate building) and 1-05-02 (melt building). A total of 154 soil samples werecollected around Line 1 and sent to a fixed-base laboratory for explosives analysis. HMX wasdetected with the highest frequency (43 of 154 soil samples). The highest value for RDX was3700 mg/kg. TNT was detected in 30 samples; the highest value was 9200 mglkg.

This report documents all site-specific activities conducted at the 31 sub-sites at IAAAP. Thenature and extent of contamination at each site is discussed. The baseline risk assessmentpresents an analysis of the potential adverse effects resulting from exposures to hazardoussubstances in soil, groundwater, surface water and sediments at lAAAP.

Table 2.4 gives the number of laboratory samples and detection levels (by building) forexplosives at Line 1. The type of explosive detected at each building is given.

September 1997 (Ref. 207)CDM Action Memorandum for the Inert Landfill at the lAAAP,Middletown, IowaLandfill, Line 1 & Line 800

The Action Memorandum for the Inert Landfill serves as the primary decision documentsupporting a non-time-critical removal action at the Inert Landfill at the IAAAP. The purpose ofthis removal action is to prevent the release of toxic wastes contained in sections of the InertLandfill Area. This Action Memorandum also addresses the excavation of an estimated101,200 cubic yards of explosives contaminated soils in Line 800 Pink Water Lagoon and theFormer Line 1 Impoundment.

Onsite land filling operations began in 1941 when lAAAP was constructed and continued until1990. The Inert Landfill covers approximately 14 acres. The average annual quantity ofmaterial disposed at the landfill operations has been estimated at 3,170 tons. The trench-fillmethod of landfill operation has been employed at the Inert Disposal Area (IDA). An entiretrench was first excavated to an approximate depth of25 feet. The excavated material wasstockpiled next to the trench and used for daily and final cover. The daily cover placed over thefill was about six inches while the final cover was at least 12 inches thick. A total of six trencheswere excavated in this manner at IDA.

Between 1980 and 1983, Trench 5 received wastes such as ash from the open burning ofexplosives and explosive-contaminated waste, the contaminated waste processor, and theexplosive waste incinerator. This explosive-contaminated waste was classified by the EPA as alisted waste. Subsequently, Trench 5 was capped and closed with a network ofmonitoring wellsinstalled to assess the groundwater quality. The hazardous constituents detected were believed tobe attributable to other wastes disposed at the Inert Disposal Area outside ofTrench 5 prior to1980.


Work Planjor Supplemental Remediallnvestigationjor Line I (Including Historical Site Assessment) -IAAAP

The report documents previous investigations including the preliminary assessment (PA) andsubsequent SI perfonned by JAYCOR that focused on identifying surface water and soilcontamination, surface water runoff, and leachate associated with the Blue Sludge Lagoon,Storage Yard, Burning Grounds Area, and Inert Landfill. The Burning Ground Area (BGA),Blue Sludge Drying Beds, and the Inert Landfill contained arsenic, cadmium, chromium, copper,lead, and zinc at levels above background.

A summary of the results obtained from the above investigation and the RI, also perfonned byJAYCOR, are included in this document. Two surface samples obtained from drainage thatoriginates at the north side of Trench 6 contained RDX up to 17.0 Jlg/L. High levels ofleadwere found in soil samples taken around the BGA and the Inert Landfill. Chromium was foundin soil samples in the open section of Trench 6, probably a leachate from the landfill. Theanalytical testing of the blue sludge material indicated no metals above levels of concern tohuman health.

SVOCs and VOCs were present in the groundwater around Trench 6, the Blue Sludge DryingBeds and Burning Area and continued to the southwest away from the site. Notablecontaminants of concern found during the Accelerated Groundwater Quality Assessment(AGQA) were Pentachlorophenol and Gross Alpha particle activity. The groundwater resultsindicate that contaminant migration from the source area had occurred. It was noted that thepresumed source of contamination is the buried landfill wastes, not the surficial soil.

The soil excavation of the fonner Line 1 Impoundment and the Line 800 pink water lagoon areto be removed in three 'tiers' with level of contamination detennining the "rank" of the soil. Thelowest level contaminated soils are used as random fill material to bring the Inert Landfill to anappropriate grade, upon which it will be capped with a geosynthetic liner. The second tier ofcontaminated soils to be excavated are to be disposed in the Trench 6 Soil Repository, which willbe constructed on-site adjacent to the Inert Landfill. The highest level contaminated soilsexcavated from the two sites will be temporarily stored in a RCRA waste pile unit, which will beconstructed northwest of the existing Inert Landfill. It is estimated that 10,000 CY ofsoil will bemanaged at the stockpile unit for eventual treatment.

Included in this action, is the disposal of the material generated from the ExplosivesContaminated Sumps Removal. A total of 57 explosives contaminated sumps and adjacent soilswere removed. This soil is contaminated with RDX, TNT, DNT, and lead and will be stockpiledin either Trench 6 or the RCRA stockpile, using the same criteria as the Line 1 and Line 800contaminated soils.

The analytical results of the blue sludge material indicates that no metals are present above levelsofconcern to human health. Furthennore, the sludge material is not considered RCRAcharacteristic hazardous waste. The Anny contracted with Mason & Hanger to remove the BlueSludge and the Blue Sludge Drying Bed material and pennanently place it in the Inert Landfill orthe Trench 6 Soil Repository.

The BGA, located in the Inert Disposal Area, contains lead up to 51, 000 ppm. Fourteenexploratory trenches throughout the BGA revealed that it is divided into a shallow zone(7,000 cubic yards) and a deep zone (12,000 cubic yards). The suggested remediation alternativewas to relocate the contaminated material in the shallow zone and place it under the geosyntheticcover of the Inert Landfill. The deep zone material would remain in situ, however, thegeosynthetic cover would be modified to extend over the deeper zone of the BGA.



Attached to the back ofthis document is a memorandum from the Department of the Anny andthe decision document describing the removal actions for the removal of contaminated soils atthe Line 1 and Line 800 Lagoon. Alternative 4, the excavation of soils and separation of thesoils into piles, one for treatment and one for landfilling, was the chosen treatment option.

October 1997 (Ref. 193A)Interim Record of Decision, Soils Operable Unit, Iowa Army Ammunition Plant

This document describes the cleanup of 25 separate areas in Line 1 from which contaminatedsoils were to be removed. The contaminated soils were adjacent to explosives productionbuildings, a vacuum pump house, and a cooling tower. Contaminants included explosives,metals, and SYOCs. Most of the soil contamination at Line 1 is from explosives and lead. Totallevels ofRDX and TNT ranged from 1000 mglkg to 9000 mglkg. Lead levels generally rangedfrom 2000 mglkg to 5000 mglkg.

4 August 1998 (Ref. 331)Darza Interim Groundwater Feasibility Study Report

Interim Feasibility Study to develop and assess potential remedial alternatives to address threatsto human health and the environment due to the presence of hazardous substances in portions ofthe Groundwater Operable Unit at IAAAP. Specifically this FS addresses groundwatercontamination associated with five on-site areas. These area are; west bum area, fire training pit,and Lines 2, 3, and 9.

This report includes a description of the site, a summary of relevant CERCLA activities that haveoccurred on the site, a description of the nature and extent of contamination to be addressed bythe remedial alternatives and an assessment of risks posed by those contaminants. The reportalso presents remedial action objectives for addressing risks and presents the identification andscreening of remedial technologies that might be applied to the groundwater operable unit.

Plant

This document presented the selected RA for Soils Operable Unit 1 at IAAAP. There is nodetailed information pertaining to environmental contamination at Line 1.

June 2000 (Ref. 144)ECC Remedial Work at Line 1 Impoundment, Summary from USACE

Contaminated soils were excavated from the lower third (southern) portion of the Line 1Impoundment and relocated to the IDA in 1997. The excavated area was lined with sedimentexcavated from the upper reaches of the impoundment area. Several truckloads of seed bankwere imported from Stump Lake.

The excavated area is filled with water contaminated primarily with RDX. The RDX levelsvaried during the 1999 sampling season from approximately 30 ~g/kg in the winter to less than2 ~glkg in the summer. Wetland vegetation that is naturally established from the imported seedbank and relocated sediment was intended to phytoremediate the contaminated residual surfacewater. Brush Creek previously flowed through the Line 1 Impoundment area, but prior toremedial action, the creek was permanently relocated to divert flows around the impoundment.



A grouted drop structure was constructed across the Brush Creek diversion channel to maintainthe water surface of Brush Creek at or above the target water surface elevation of 671.5 ft in theLine I Impoundment. Maintaining the impoundment water surface elevation at or below thesurface elevation- of the creek prevents contaminated water in the impoundment from seepinginto Brush Creek.

A Texas Crossing is located on Brush Creek to provide access to the upper and lower hydrauliccontrol structures and several monitoring wells. The Texas Crossing consists of four I8-in.diameter CMP culverts positioned below a reinforced concrete slab that allows vehicular access.The inlet elevation of the culverts is 972.0 ft. The upstream ends of the culverts have stop logslots that can be plugged to raise the elevation of Brush Creek to approximately 974ft.Sandbags can also be placed on the Texas Crossing to further increase the surface elevation ofBrush Creek, allowing Brush Creek flows to be diverted into the Line I impoundmentphytoremediation wetland treatment reservoir. Water in Brush Creek adjacent to the Line Iimpoundment is contaminated with RDX at concentrations of approximately 10 Jlg/kg.

Two hydraulic control structures are located on the Line I Impoundment. The upper hydrauliccontrol structure, on the north (upstream) end of the impoundment, is used to divert water intothe impoundment from Brush Creek. The lower hydraulic control structure is on the south(downstream) end of the impoundment and is used to control the water surface elevation in theimpoundment and to discharge water from the system. The lower hydraulic control structure isequipped with a slide gate and stop logs.

A pre-engineered metal building is located near the lower hydraulic control structure to houseGAC units.

2.5 Interviews Related to Site History

TN&A conducted interviews in June, September, and November 2000 with former and presentemployees ofIAAAP. The purpose of the interviews was to gain insight into the operations andprocedures previously used at Line 1. Gathering historical information about the materials used,buildings that stored, melted, or machined these materials, and the methods of wasteremoval/handling was also an objective.

Some interviews were conducted with individual employees, while others consisted of sessionswith at least three former/present workers. For one interview session, American Ordinanceprovided a large passenger carrier van for the group to tour the site while discussing plantoperations.

The occupations of the interviewees ranged from storage operators and health and safety officersto chief chemists and engineers. Some of the employees worked at the plant as far back as 1946,while others started in the late 1950s and continue to work there today. All of the employeeswere asked to identify, from their own direct first-hand knowledge and experience, areas onLine 1 that are or could be potentially contaminated and deserve further investigation.

Pertinent information obtained from the interviews with the individual(s) are summarized in thissection. The information is tabulated for clarity. For a complete viewing of the interviewtranscripts, see Appendix L.

2.5.1 Buildings with Potential Contamination

The former/present employees were asked to talk about areas on Line 1 that may have beencontaminated during Army and AEC operations. TN&A found that 50 to 60 of the buildingslocated on Line 1 were mentioned by the interviewees at least once for having the potential forcontamination. TN&A used the frequency that a building or group of buildings was mentioned asa guide to the likelihood of contamination. The following table shows the total number of timesa particular building was mentioned:

Work Plan for Supplemental 8emedial Investigation for Line 1 (Including Historical Site Assessment) - IAAAP

• Creeks ran red from TNT contamination.

• The death of two people resulted from a "Blue Flash" in a cell. (This could not besubstantiated- after reviewing hundreds of documents and media reports or through interviewswith other lAAAP personnel.)

• No known chemical or radiological spills occurred on Line I.

• Disassembly of munitions occurred at Line I after Desert Storm.

June 12, 2000, Interview with CR

Information on the following topics was obtained from the interview:

• It is suggested that the melt buildings are areas that may be contaminated.

• The C Yard handled Comp Band cyclotol type explosives (mixtures ofRDX and TNT). Anarea within the C Yard, called CC, contained classified explosives.

• TNT in streams was reduced from 32 ppm to 1 ppm after adding fly ash to the streams.

• Building 1-11 was a central storage area for all of the raw materials.

• Obsolete bombs were destroyed in Yard "E" by crushing them with semi trucks. Theexplosive pit is suggested to have been taken to Line 1. Barium was thought to have beenpresent in the metal of these bombs.

• Security at the plant was strict. Everyone wore film badges, which were switched every fourmonths. Employees also carried radiation monitors where necessary.

September 2000 Interview with JS

Information was gained on the following topics during the interview.

• Boron and barium-based explosives were machined in Building 1-40. Some machining wasdone in 1-10 and 1-12. The purpose of machining the explosives was to get the exact shape.

• When machining explosives, water running to prevent sparks was diverged outside themachining buildings and into Building 1-70 for filtration.

• No machining ofDU occurred on Line 1.

• DU was handled in Buildings I-II, 1-12, and (mostly) 1-40.

• Tritium bottles were stored in Building 1-11.

Interview with JP and GF


• Waste streams were treated with active carbon from fly ash from the power plant.

• Small sediment ponds, less than an acre each, were upstream of the Pink Water Lagoon tocatch sediment.



• It is suggested that the west bum pad may contain cyaneric acid and penirisitol, bariumsulfate, and barium nitrate.

• Baratol is a mixture of TNT and barium nitrate.

• Explosives were originally made by melting and casting the explosive into the proper shape.Later, plastic explosives were pressed into shape, instead of cast. Each particle was coatedwith a thin layer of plastic material to mold the shape.

• Machining of explosives was done in Building 1-10. Machining also occurred in Building1-40. PBX and Comp B were machined there.

• Piping from the melt building was installed to go to a filtration system/treatment building in1958 or 1959. The filtration system eventually took place in Building 1-70.

• Vacuum separators were used for collecting explosive dust.

• An explosion of Building 1-05-01 occurred in 1943 and killed about 20 people.

• An explosion of a building in Yard E killed 2 or 3 employees.

• The hydro-shot is described as being football shaped with a DU ring around it. A detonatorstuck out from the top and bottom. The hemisphere was made of explosives. Only half ofthe shot was fired at a time during test firing.

November 29, 2000, Interview with JP, DF and LP


• There was no drilling of radioactive material done at the plant.

• The different types of explosives (TNT, RDX, HMX, etc.) used at operations are discussed.This mixture of TNT, RDX, and HMX is called cyclotol.

• Raw materials coming in to the plant worked their way to the 1-50 building, and then over tothe melt buildings (1-05-1 and 1-05-2).

• Building 1-15 is mentioned as having been an assembly building.

• Building 1-100 was the X-ray building. X-ray rinse water was washed into the sanitarysewer.

• Finished machining took place in Buildings 1-10 and 1-12. Gross machining took place inBuilding 1-40, where 200-300 gallons of water and waste explosives a week were taken to alagoon.

• Rest buildings were buffers between operations where explosives were allowed time betweenoperations, not areas with any contamination.

• Buildings 1-12 and 1-40, where machining operations took place, are likely to becontaminated. Pressing operations associated with plastic bomb explosives is suggested tohave caused contamination in Building 1-10, also a machining building.



• Screening and blending operations are discussed. Most of the dust from screening andblending explosives were swept up dry, but there was some wash down. There was nocollection system for the waste water washed out of the screening buildings.

• A lagoon behind the Building 1-55 cooling tower is mentioned.

• Machining waste goes to the sumps. Concrete sumps would freeze and crack, leakingcontaminated water.

• Wooden weirs were used to separate solids and TNT precipitate out of waste water.

• Use ofMethylene-bis-ortho-chloraniline (MOCA) in mixing of bonding agents occurred inBuildings 1-53, 1-60, and 1-61. It is indicated that in 1961, MOCA was still being used.

• Carbon tetrachloride and trichloroethylene were used as solvents for cleaning. Thesesolvents were stored in solvent storage bays. Excess solvents were burned along with theirstorage containers.

• Tritium bottles were stored in Buildings 1-11, 1-77 and 1-60.

November 29, 2000, Interview with DL

Information was gained on the following:

• Contaminated water gutters behind Building 1-12 were replaced with sheet metal.

• Clarifiers were located behind Buildings 1-10 and 1-12. Water from the clarifiers weredischarged into a ditch.

November 30,2000, Interview with DM

The following topics were discussed:

• Troughs carry contaminated water through clarifiers, which filter out the explosives. Then,the water is 'turned loose' into an open ditch, which eventually goes to the Red WaterLagoon.

• Buildings 1-70, 1-12, and 1-05-2 all had drain troughs.

• Some contaminated water originated beneath the buildings and was pumped above groundinto aluminum troughs.

• Carbon water filters were not used until the late 1960s or early 1970s.

• Building 1-70 had an explosive filter for contaminated water. This water was diverged to asump in the NW comer of the building, and then to the Red Water Lagoon.

• The pipes that eventually took contaminated water to the sumps or ditches had filters every10 feet. Doors were placed every 10 feet as well to clean the filters. The explosive materialcaught by the filters was taken to the burning grounds.

• The most contaminated area is suggested to be around Building 1-05-2. An area betweenBuilding 1-05-2 and the carbon filter house was a problem area with spills.

• There was no sump to collect water from the X-ray Building (Bldg. 1-100).

• Waste water in Building 1-40 (machining building) was collected by trough and went into asump. The sump eventually had carbon filters. A settling tank for Building 1-40 waste waterwas located on the surface. Waste water was also piped underground from Building 1-40 tothe Red Water Lagoon.

• Interviewees assert that any "Blue Flash" never occurred at IAAAP.

• Building 1-11 was used mostly for storage. There was no open water of any kind.

November 2000 Interview with BS

The topics discussed during the interview were:

• Building 1-77 was a receiving building. ActIvities in 1-61 consisted of assembly work. HEmachining was done in Building 1-40. The north half of 1-12 was used for machining, andthe southern halfwas used for pressing. Building 1-53 also had pressing operations.

• PBX was used in the pressing cycle.

• The melt buildings were used to pour explosives before the plastic bonding explosives wereintroduced.

• There was a main drainage between the two cast melting buildings, 1-05-1 and 1-05-2 .

• Fly ash was dumped into Brush Creek from the power plant between Line 1 and Line 2 totreat for explosives in the surface water.

• Acetone and trichlorethylene were common solvents used during plant operations.



November 2000 Interview with AL

Infonnation was gained on the following topics during the interview:

• Building 1-40, the underground building, machined mostly HE explosives; however, theremay have been some incidental and unintentional machining ofDU, where DU may havebeen "nicked" during explosives machining.

• HE machining was also done in Buildings 1-10 and 1-12.

• Building 1-40 generated large quantities of waste water, more than Buildings 1-10 and 1-12.This water was pumped into a ditch after going through setting tanks and carbon columns.The settling tanks were occasionally cleaned out, and the material was taken to the BurningGrounds.

• Building 1-50 was a transfer building for material going to the melt buildings. After the meltbuildings, material was temporarily held in the Rest Houses 1-71, 1-72, 1-74, 1-75, and 1-76.

• Building 1-100 was an X-ray building. Some sawing ofHE may have been done there(sawing off the horizon).

2.5.3 Other Information Obtained from Interviews

The following areas were also discussed during the site personnel interviews:

Production Operations at Line 1

Infonnation concerning historic production facilities was obtained from personnel interviews(Appendix L). Building 1-61 was for assembly, Buildings 1-40 and 1-12 were used for HEmachining, and Building 1-13 was final assembly. Building 1-11 was primarily used for storage.Rest buildings were buildings in which munitions and components were allowed to betemporarily stored to reach thermal equilibrium with the production facilities.

Sediment Ponds

Any settling pond(s) upgradient from the Pink Water Lagoon at Line 1 would have existed priorto 1957. The ponds were less than an acre in area and 1 or 2 feet deep and were located betweenthe conveyors of the melt buildings. It was common practice to open the doors and wash thewater on the ground when washing down the melt buildings. Prior to the 1960s, the water wouldsettle in natural depressions and then run into ditches to Brush Creek. The water in the ditches atLine 1 is reported to have been red from TNT contamination.

Radiological

DU, tritium, beryllium, and plutonium were used during the atomic weapons production periodat Line 1. DU was handled in Buildings I-II, 1-12, 1-13, 1-61, and 1-40. Tritium bottles werestored in Building 1-11. According to engineers, safety and production personnel, all radioactiveatomic bomb core material received at the plant arrived pre-made. There was no machining,cutting, sanding or drilling of radioactive material. It is possible that some incidental nicking ofDU was done during the machining ofHE in Building 1-40. This would generate small amountsofDU trimmings, which could have been washed into the sumps. It was standard operating



procedure that plutonium and tritium containers were swipe tested by the Safety Department. Nocontamination or leakage was found during these tests.

There have been no lethal or toxic chemical warfare agents stored or handled at lAAAP.



3.0 HISTORICAL SITE ASSESSMENT

The following section contains an area-by-area summary of each ofthe Line 1 structures that havehad or potentially could have had contaminant releases into the environment. Areas not includedare support structures such as guardhouses, change houses, cafeterias, personnel shelters, andbuilding ramps. Based on historical research, these areas were not considered potentialenvironmental contamination sources. To find information on the buildings or structures notincluded in this summary, see Section 2.2, "Complete Historical Review of Buildings."

The following building groups are discussed below:

• Melt Buildings

• Machining Buildings

• Storage and Material Inspection Buildings

• Component Rest Houses

• X-ray Buildings

• Research and Development Buildings

• Filter Buildings

• Drainage Ways and Impoundments

• Other Areas of Environmental Concern

3.1 Melt Buildings

As part of the first group ofbuildings constructed on Line 1, Melt Buildings 1-05-1 and 1-05-2started operations in September 1941. Currently, these buildings are in layaway status. However,historically, the melt buildings have released explosives-contaminated wastes to Brush Creekthrough drainage ways as a result of explosive melt pouring operations.

Throughout this history, the explosive melts consisted of ammonium nitrate, TNT, boron-basedexplosives, barium-based explosives, RDX, HMX, and PBX. Different mixtures of these baseexplosives and other compounds produced amatol, Composition B, baratol, boracitol, cyclotol, andboracitol melts, respectively. These melts were used in production of explosive components forshell munitions and nuclear weapons.

During Army operations from 1941 to 1947, the melts consisted primarily ofTNT and ammoniumnitrate mixture. The mixture was prepared by melting TNT and incorporating ammonium nitratewith it long enough to ensure that each grain of ammonium nitrate was thoroughly coated withTNT.

This mixture was poured into shells by a funnel. During the pouring process, a small amount ofTNT tended to crystallize on top ofthe outside of the shell. This excess TNT was removed. Toprevent accumulation, the floors were steam-cleaned daily. The water from these cleanings waswashed outside of the doorways into open drainage ways.

During ABC operations of Line 1 (1947-1975), melts consisted ofbaratol, baracitol, TNT,Composition B, and/or cyclotol. These melts were used to make explosive casts, often generically

Line 1 Work Plan for Supplemental Rl.doc - 9/20/2001 Page 3-1Historical Site Assessment


called "Baratols", as a component in nuclear weapons. See Section 2.4, "Historical DocumentReview," Ref. 187, for AEC operations from 1947 to 1954 for more detailed information.

Explosive effluent-from these melts continued to be discharged into drainage ways outside the meltbuildings until clarifiers and sumps were later built to temporarily contain and filter out explosivesludge material from the effluent. Clarifiers appear on 1948 engineering drawings outside both the1-05-1 and 1-05-2 melt buildings (see Section 2.1).

This system was updated when a contaminated water treatment system was installed throughoutLine 1 in 1962. This water treatment system consisted of connected piping from sumps leading to acentral point for treatment (see Section 2.4, Ref. 162). This piping was identified and photographedduring site walkovers connected to clarifiers.

Based on site personnel interviews (see Section 2.5), the concrete sumps sometimes overflowed,spilling the explosive effluent on the ground. These sumps were excavated by OHM RemediationServices in 1995. Findings during this remediation effort identified explosives and metalscontamination..See document review Section 2.4.2.8, "Sump Removal Documentation," for details.

The existence and general location of two sediment ponds (no longer present) were revealed duringpersonnel interviews. These two sediment ponds were historically located somewhere between themelt building conveyor system. The conveyor system is the covered ramp structure leading outfrom Building 1-50 to both melt buildings. These structures were believed to have been in use priorto 1957. Additional data on the sediment ponds was not found.

More detailed information about the waste water operations at Line 1 melt buildings could not belocated throughout the research of historical documents, drawings, aerial photgraphs, andinterviews. Sampling locations were chosen based on available historical information of past meltbuilding operations and analytical results of the previous RI.

3.2 Machining Buildings

The machining buildings group was historically the primary producer of explosive-contaminatedwaste at Line 1. Reportedly, the largest releases of the explosive effluent from Line 1 occurredduring ABC operations (1947-1975) as a result of explosive machining. Machining of explosivesoccurred in Buildings 1-10, 1-40, 1-12, and 1-100. X-ray Building 1-100 was used to machineexplosives during the quality assurance process. (For information on X-ray operations at 1-100, seeSection 3.1.5 below.)

Machining operations primarily consisted of the machining of an explosive cast that would bedesigned to fit around the core of a nuclear weapon. These explosive casts were originally madewith baratol or boracitol. Other explosive constituents used in these castings were Composition Band TNT. Two of the main solvents used in the cleaning and maintenance of the machiningequipment were trichloroethylene (TCE) and acetone. Available historical records do not revealsolvent waste management practices nor the quantities of solvents used.

From interviews with former employees, it was learned that explosive casts were replaced bypressing plastic explosives into a needed shape. These pressing operations occurred inBuilding 1-12.

,6-;

Line 1 Work Plan for Supplemental RJ.doc - 9/20/2001 Page 3-2Historical Site Assessment


During machining operations, water coolant was used to prevent sparks. Water was also used inwashing down floors to remove explosive machine waste. During early AEC operations in thesebuildings, waste water may have flowed directly into drainage ditches leading to Brush Creek.Based on former employee interviews, waste from explosive machining operations atBuilding 1-100 flowed directly into a drainage ditch located outside of the building. Also, oneemployee remembers waste water from Building 1-40 being connected via a pipeline directly to theLine 1 Lagoon.

In subsequent years, the waste water from the coolant along with wash water from the floors wassent to a sump located outside the machining buildings. The sumps were connected to clarifiers thatremoved consolidated matter. Waste water from the clarifiers was connected to carbon filtrationsystems via aboveground pipeline. After carbon filtration, the effluent was discharged into drainageditches. The carbon filtration system for effluent from Buildings 1-10 and 1-12 was located in filterBuilding 1-70. Building 1-40 had a carbon filtration system located just outside, close to theclarifier. Also in later years, contaminated water from the machining operations in 1-100 flowedthrough aluminum-lined gutters to the Filter Building 1-70. (For more information onBuilding 1-70, see Section 3.1.7.)

Sumps from Buildings 1-40 and 1-12 were removed by OHM Remediation Services in 1995 (seeSection 2.4.2.8). The OHM document does not report any sumps being excavated fromBuilding 1-10. However, it has been documented through interviews and historical documents thatclarifiers and piping leading to a carbon filtration system in Building 1-70 were present atBuilding 1-10, which is the same as Buildings 1-40 and 1-12. This information would suggest thatsump(s) would be present at 1-10 to have the same effluent treatment system as the other machiningbuildings, 1-40 and 1-12.

Based on interviews (Section 2.5), DU was handled in Machining Buildings 1-40 and 1-12.Employees explained that "nicking" of the DU during machining operations did not occur veryoften. Machining was performed on the explosives, and the "nicking" ofDU was unintentional.This is confirmed by a 1969 document (Section 2.4, Ref. 135) that stated that a small amount ofDUturnings from machining operations mixed with explosives was disposed of at the burning area.[According to the 1969 SOP (Ref. 135), the burning area referred to here was the East Bum Pad].

3.3 Storage and Material Inspection Buildings

Historically, a wide range of materials and chemicals was stored at Line 1. The major groups ofmaterials stored are explosives, radiological materials, and solvents. In most cases, only the generaluses of these storage buildings are known. Specifics about the amount of storage, the individualmaterial names, and cleaning practices were not found during historical record research.

For clarity, the narrative for these building groups is divided under the subsection headings below.

Explosives Storage Buildings

Explosives were generally stored in Buildings 1-06-1, 1-06-2, 1-08-1, and 1-50.

With the exception of 1-50 (Transfer and Inspection Building), these buildings were used almostexclusively to store newly shipped TNT and ammonium nitrate during Army operations in the earlyto mid 1940s. During AEC operations (1947-1975), these buildings reportedly stored raw

Line I Work Plan for Supplemental Rl.doc - 9/201200 I Page 3-3Historical Site Assessment


explosive materials, including TNT. Building 1-50 was used as a central transfer point and was usedfor inspection before the explosive materials were moved by conveyers to the two melt buildings,(1-05-1 and 1-05-~).

Radiological Materials Storage Buildings

Radiological material storage has been identified in Buildings 1-11, 1-12, 1-13, 1-61, and 1-40.TN&A is not scoped to sample for radiological contaminants at Line 1. This subsection has beenadded to inform the reader and the TN&A field team collecting non-radiological samples in areaswhere radiological contamination could exist. Samples will be scanned for radiologicalcontamination for worker safety. (See Appendix A Field Sampling Plan for more information.)

Radiological materials such as DU and tritium were stored to be used in production of nuclearweapon components. Historical records do not indicate specifically to what DU stored at Line 1 isassociated. The historical records did not show that DU was stored or used during Army control ofLine 1 (1941-1947, 1975-Present). Building 1-11 was a main storage area used by AEC. Interviewsrevealed (Section 2.5) that radiological materials stored there were DU and tritium bottles. Littleelse is known about any other radiological materials stored there.

Buildings 1-13 and 1-61 were also used to store DU. Building 1-13 was used for final nuclearweapons assembly and 1-61 was used for shipping.

Solvent Storage Buildings

Solvents were stored generally in Buildings 1-03-1, 1-03-2, 1-03-3, 1-03-4, 1-03-5, 1-03-6, and1-03-7. Solvents stored were reportedly TCE and acetone. Available documents do not definespecific information regarding the management of solvent wastes, the quantities of solvents, and thetypes of solvents used at Line 1.

3.4 Component Rest Houses

Component rest houses were temperature controlled to allow munitions time between operations toreach thermal equilibrium evenly. Buildings 1-71, 1-72, 1-74, 1-75, and 1-76 were the first resthouses, built in 1941. When AEC took control of operations at Line 1, Building 1-07 was built toincrease production. Historically, the areas around these rest houses appear never to have beensampled. Environmental contamination from these buildings is unlikely. However, no data areavailable to support the notion that the soils around these building are below action levels.

3.5 X-ray Buildings

Buildings 1-100 and 1-73 were used as X-ray Buildings. These buildings housed equipment used totake X-rays of completed components to find flaws and collect data needed to make improvements.X-ray Building 1-100 contained two 1,OOO,OOO-volt X-ray machines. X-ray Building 1-100 was alsoused to machine explosives during the quality assurance process. For the sampling rationale appliedfor buildings used for machining of explosives at Building 1-100, see Section 3.1.2 above.

Building 1-12 contained X-ray machines for employee training and for backup use. This area isdiscussed in Section 3.1.2 above.

"s-

Line I Work Plan for Supplemental Rl.doc - 9/2012001 Page 3-4Historical Site Assessment


The potential contaminants suspected at the X-ray Buildings are metals. The primary metal ofconcern is silver from the X-ray processes.

Interviews indicate that there was no sump to collect waste water from 1-100. (See Section 2.5.) Insubsequent years, contaminated water flowed through aluminum-lined gutters to the filter building1-70.

3.6 Research and Development Buildings

Some of the main R&D programs over the years at IAAAP were electrolytic disposal of lead azide,activated carbon regeneration for red water control, and explosives development involving bariumnitrate and TNT. Labs for plastics and MOCA were present in Building I-53.

The R&D buildings, with their AEC names, are 1-03 Explosives Testing Lab, 1-04 Baratol Lab, and1-60 Barium Nitrate Lab; I-53 was historically a plastics lab where MOCA was prepared. MOCA isa curing agent used in liquid urethane polymers and epoxy resins. In addition, Building 1-60 wasconverted into a plastics lab in 1962.

Available documents do not indicate MOCA waste management practices. Through interviews, itwas determined that MOCA was used at Buildings I-53, 1-60, and 1-61. Air sample results indicatethat MOCA was also used in Buildings 1-10, 1-12, 1-40, and 1-61 (Refs. 317, 318, and 319).Documents suggest that MOCA was also used in Building 1-04 (Ref. 303). Possible releases willbe determined through the collection ofVOC soil samples surrounding these buildings.

Before AEC operations (pre-I 947), Building 1-03 was known as an equipment test lab. Not much isknown about operations of this building during this time period. However, during AEC operationsthis building was used in testing sample baratol casts. These casts were used as components innuclear weapon production. This building also contained a sample cast crusher. Disposal methodsfor these discarded explosive casts are not known.

During Army operations (1941-1947), Building 1-04 contained line offices and was used forgeneral purpose and maintenance. Building lists from this time period show Building 1-04 asreceiving and storage (1944) and receiving and painting (1946). (See Section 2.2, BuildingsReview, for more building information.) Early AEC operations (1947-1975) in the building includea baratollab. This baratollab was used for research and development in the production ofbaratolcasts. Specific details about the operations of this lab are not known.

Building 1-60 was constructed by AEC in 1951. This lab was used in the preparation of bariumnitrate that was used to make baratol. Specific details about the operations of this lab are notknown.

Building I-53 was used as a chemical equipment and material facility when it was first constructedin 1941. Operations during this time period are not known. During AEC operations, Building I-53was a plastics lab. Specific operations at this lab during AEC operations are also not known. A 1948engineering drawing shows a pipe leading from Building 1-53, discharging into a ditch west of thebuilding.

It is not known how waste was disposed of in these buildings. Based on interviews with formeremployees, wastes were often disposed outside the doorways and in drainage ways. Based on this,

Line I Work Plan for Supplemental RI.doc - 9/20/2001 Page 3-5Historical Site Assessment


potential for environmental contamination exists for explosives and metals around Buildings 1-04,1-03, and 1-60 from explosive casting components.

Areas around the doorways and drainage ways of Building 1-53 have the potential for explosives,VOCs, SVOCs, and metals contamination. Also, the pipe leading from the building could be apotential location for contamination.

3.7 Filter Buildings

Buildings 1-70 and 1-70-1 are filter buildings built during AEC operations of Line 1 to treatexplosive-contaminated effluent released from explosive component production buildings.

These buildings contain clarifiers that removed explosive sludge and carbon filtration systems thatremoved dissolved explosives from the effluent. After the effluent passed through the carbonfiltration system, it was discharged into a drainage way leading to the Line 1 impoundment. Frompersonnel interviews, it was discovered that the explosive sludge from the filters were taken to theburning area and incinerated.

3.8 Drainage Ways and Impoundments

The network of drainage ways located nearby the majority of the buildings on Line 1 has the highestpotential for environmental contamination from explosives and metals than any other area. Basedon interviews with former employees, the drainage ways around buildings were used to carryeffluent to Brush Creek. Washing out buildings into drainage ditches, "washdown," was a commonwaste disposal practice, as explained by interviewed former employees. During AEC operations,Line 1 became the largest source of explosive-contaminated waste to Brush Creek (Ref. 187).Water in these drainage ditches was reported to have been red with TNT contamination.

During interviews with former employees, it was also discovered that sediment ponds upgradientfrom the Line 1 impoundment located at Brush Creek existed prior to 1957. These ponds werereportedly less than an acre in area and 1 or 2 feet deep. The ponds were located between theconveyors of the melt buildings.

Historical records and information from interviews pertaining to these ponds are very limited. Theclose proximity of the sediment ponds to the melt buildings may indicate possible contaminationpresent in these former sediment ponds.

3.9 Other Areas of Environmental Concern

Wood and Metal Shops

Buildings 1-01 and 1-148 contain the wood/metal shops (1-01) and tool/die shops (1-148).

During 1941 to 1947, Building 1-01 was used as an inert pour and maintenance shop. Little isknown about operations during this time period, except that the building was used for storage andshops.

Wood boxes were made for containing munitions before shipping in Building 1-01 during AECoperations. Specific metals operations are not known.

Line 1 Work Plan for Supplemental RI.doc - 9/20/2001 Page 3-6Historical Site Assessment


Building 1-148 was built in 1978 and used for maintenance of tools. No other information could befound on past operations of this building.

Fuel Tanks

Fuel storage tanks 1-152-1, 1-152-2, 1-152-9, 1-152-10, 1-152-11, 1-152-12, and 1-152-13 arelocated on the north end of Line 1. These fuel tanks have a capacity to store 125,000 gallons eachand were installed from 1973 to 1976. These fuel tanks contain No.2 fuel oil to be used by thePower Plant Buildings 1-62 and 1-148. A potential for contaminated soil from released fuel existsin this area.

Cooling Towers

Cooling towers 1-155-1, 1-155-2, and 1-155-3 were installed by AEC and provided water recoverywhen water consumption was high. Cooling towers were located at Buildings 1-10 (1-155-2),1-12(1-155-3) and 1-60 (1-155-4) to provide cool water for air conditioning utilities, and at 1-05-1and 1-05-2. A double cooling tower (1-155-1) was installed to provide the necessary cool water forprocess operation. At other smaller air conditioning installations, such as Buildings 1-04 and 1-01,evaporative coolers were used.

Processes in the cooling towers reportedly released hexavalent chromium to Brush Creek duringAEC operations. Hexavalent chromium was used as an additive to control corrosion and deposits inthe cooling towers. A water sample collected at Line 1 had reported 0.77 ppm hexavalentchromium during 1971. The most restrictive quality standard was reported as 0.05 ppm (Ref. 372).

The cooling towers have not been in operation for many years, possibly decades, and therefore havenot recently contributed chromium contamination to the surface water.

3.10 Conclusion

Through historical research many areas have been identified as potential or known areas ofenvironmental contamination. These areas have been identified as melt buildings, machiningbuildings, storage buildings, rest houses, X-ray buildings, research and development buildings,shops, cooling towers, storage tanks and drainage ways. For sampling rationale and samplelocations on the areas identified above, see Field Sampling Plan (Appendix A). For additionalinformation on the areas identified in this section, see the historical engineering drawing review(Section 2.1), the buildings review (Section 2.2), the historical aerial photographs review(Section 2.3), the historical documents review (Section 2.4), and the interviews with formeremployees (Section 2.5).
