1.0 INTRODUCTION

1.1 GENERAL

This report, prepared by Conestoga-Rovers & Associates

(CRA), the Supervising Contractor, on behalf of the City of Charles City and

Solvay Animal Health, Inc., presents a summary of remedial activities

completed under the Remedial Action Plan (RA Plan) associated with

Operable Unit 1 (OU1) at the Shaw Avenue Site.

The Shaw Avenue Site (Site) is located along the

southeast limit of the City of Charles City, Floyd County, Iowa, as shown on

Figure 1.1. The Site is situated south of Clark Street, approximately 500 feet

east and 200 feet north of the Cedar River. The Site is owned by the City of

Charles City. The City of Charles City Wastewater Treatment Plant (WWTP)

is located immediately to the east of the Site.

The Site historically has been subject to both Iowa

Department of Natural Resources (IDNR) and United States Environmental

Protection Agency (U.S. EPA) studies and evaluations (see Section 2.0,

Remedial Investigation Report). The historical studies and Site evaluations

and the history of previous operations contributed to the ranking of the Site

under the National Priorities List (NPL) with a Hazard Ranking System

(HRS) score of 30.01 (40 CFR Part 300, Appendix B) (EPA, 1985).

The Site was subject to a Remedial

Investigation/Feasibility Study (RI/FS) and Baseline Risk Assessment (BRA)

from June 1988 through to June 1991. Based on the RI/FS and BRA, a final

Record of Decision (ROD) was executed on September 26, 1991. The ROD

specifically pertained to Operable Unit 1 (OU1): the chemical fill and

surrounding contaminated soil. The remedy selected in the ROD included

the following:

i) In situ fixation/stabilization of chemical fill and contaminated soil

exhibiting concentrations above total arsenic or cadmium performance

standards to TCLP based performance standards;

ii) Installation of a low permeability cap to protect the fixated/stabilized

material; and

iii) Groundwater monitoring will be continued during and after

implementation of the fixation/stabilization remedy to determine the

effectiveness of the remedy in preventing leaching of contaminants to

the groundwater.

The ROD also specified that if treatability testing showed

that stabilization/fixation was ineffective for the chemical fill and

contaminated soil, these materials would be excavated and removed to a

RCRA approved landfill.

Subsequent to issuance of the ROD, Solvay Animal

Health, Inc. (SAH) commissioned Chemical Waste Management, Inc. (CWM),

the RA Contractor, to perform preliminary stabilization/fixation treatability

testing on chemical fill samples. Based on the treatability study results and

other supporting stabilization data, U.S. EPA determined that the technology

to implement the in situ fixation/stabilization remedy selected by the ROD

would not be adequate. Therefore, pursuant to the ROD, the remedial action

consisted of excavation of the chemical fill and surrounding contaminated

soil and off-Site treatment, as necessary, and disposal. The change in the

remedy was accomplished through an Explanation of Significant Differences

(ESD).

On February 28,1992, the City of Charles City and SAH

entered into a Consent Decree (CD) with U.S. EPA Region VII for remediation

of OU1. Consistent with the ROD and pursuant to the CD, the remedial

action for OU1 consisted of excavation, treatment and disposal of chemical fill

and excavation and disposal of contaminated soil exhibiting concentrations of

arsenic or cadmium above the performance standards. The performance

standards pursuant to the ROD and CD were: 50 ppm for total arsenic; and

20 ppm for total cadmium.

In April and May 1992, the remedial action for OU1 was

completed. The chemical fill was treated prior to landfilling at a CWM

authorized RCRA landfill using the best practical means as determined from

CWM treatability studies and the availability of treatment facilities at the

CWM authorized RCRA landfill. The contaminated soil was landfilled,

without treatment, at a CWM authorized RCRA landfill.

Pursuant to the CD and as specified in the SOW, the

remedial action for OU1 also included the excavation and disposal of an

on-Site underground storage tank which was conducted in accordance with

the state of Iowa and federal underground storage tank regulations. The tank

was cleaned at the Site and was disposed of by the City of Charles City as scrap

metal.

The primary objective of the RA Report is to describe the

implementation of the remedial action for OUI which was carried out within

the terms and conditions of the CD and the RA Plan.

1.2 SITE BACKGROUND

Background for the Shaw Avenue Site is summarized

herein based on the detailed presentation in the RI report (CRA, 1990).

1.3 SITE DESCRIPTION

The Shaw Avenue Site is an elongated site, approximately

24 acres in size, running northeast to southwest, with a length of

approximately 2,000 feet and an average width of approximately 525 feet. The

Site runs parallel to and is bounded to the west by the Iowa Terminal

Railroad tracks to a point where the tracks turn west and cross the Cedar

River. The Site, with the exception of chemical fill identified at the north end

of the Site, is bounded to the north and east by a chain-link fence with locking

gates and to the south by the Cedar River and tree line. Figure 1.2 presents

the approximate Site boundary.

The Site and surrounding area include a high area at the

northeast and low point at the south/southwest perimeter of the Site. The

Site and surrounding area generally slopes from the northeast to the

south/southwest. The northeastern elevation is approximately 1,020 feet

above mean sea level (AMSL) and the south/southwest elevation is

approximately 980 feet AMSL.

The 100-year flood boundary at the Site varies from an

elevation of approximately 995.5 feet (AMSL) at the northern end of the Site

to approximately 994 feet AMSL at the southern end of the Site. Figure 1.3

presents the 100-year flood boundary in the vicinity of the Site. The 100-year

flood boundary is based on the "Department of Housing and Urban

Development, Federal Insurance Administrative, City of Charles City, LA,

Floyd Co., Flood Hazard Boundary Map H-04, Flood Insurance Rate Map 1-04".

The south/southwestern portion of the Site and most of

the area west of the Iowa Terminal Railroad tracks are situated within the

100-year flood boundary. The northeastern portion of the Site, in the vicinity

of OU1, is located above the 100-year floodplain. The ground surface

elevation, in the vicinity of OU1, ranges from approximately 1,006 feet AMSL

to approximately 1,010 feet AMSL.

The City of Charles City acquired the Site in sections,

beginning with its acquisition of the northern part in 1899. The City acquired

the middle section of the Site in 1953, and the southern section in 1964.

Municipal refuse disposal operations commenced at the Site prior to 1949.

Sludge from the City of Charles City WWTP was disposed at the Site from

1949 to 1964. Disposal of bulk construction debris, trees and leaves and open

burning has occurred at the Site. The City of Charles City continues to use the

Site for disposal of liming sludge from the City's WWTP.

The Site was also used for waste disposal by Solvay

Animal Health, Inc. (SAH), formerly known as Salsbury Laboratories, Inc.,

from 1949 to 1953. The RI report (CRA, 1990) concluded that the chemical fill

identified at the north end of the Site (see Section 1.2.3) exhibited

characteristics of process wastes as identified by SAH's review of its

production records (Salsbury, 1987).

1.4 REMEDIAL INVESTIGATION SUMMARY

The Remedial Investigation (RI) was completed in two

phases and included the excavation of three test pits, 93 boreholes, the

installation of 25 monitoring wells, as well as the collection and analyses of

six subsurface chemical fill samples, 11 subsurface soil samples, four

composite surface soil samples, 110 groundwater samples, three wastewater

samples, two discrete surface water samples and in excess of 63 composite

surface water samples. Figure 1.4 presents RI monitoring and sampling

locations.

The RI achieved its objective to identify and characterize

the nature and extent of contaminant release from the Shaw Avenue Site.

1.5 NATURE AND EXTENT OF CONTAMINATION- OPERABLE UNIT 1____________

Chemical fill was identified at the Site during the RI

through the installation of 93 exploratory boreholes and three test pits. In

February 1992, an additional 37 boreholes were completed at the Site to

further define the extent of the chemical fill and contaminated soil. The soil

boring program was discussed in detail in the Field Sampling Plan (see

Appendix D in the RA Plan). Based on the borings and test pits completed at

the Site the extent of chemical fill was delineated, as shown on Plan 1,

enclosed. The chemical fill was located approximately two to three feet below

ground surface and generally extended vertically to the top of bedrock. The

thickness of chemical fill encountered ranged from 0.5 to 9.5 feet. The total

volume of chemical fill identified was calculated to be approximately

670 cubic yards.

The chemical fill identified on Site was characterized by

the presence of arsenic (up to 50,000 mg/kg) and orthonitroaniline (ONA) (up

to 95,000 mg/kg) and to a lesser extent by relatively low concentrations of

various halogenated organic compounds (<1 mg/kg), aromatic hydrocarbons

(<1 mg/kg) and various metals. The chemical fill was the source of arsenic

and orthonitroaniline contamination in the groundwater.

A 1,000-gallon underground gasoline tank was also

located in the vicinity of the chemical fill. The tank was considered to be a

possible source of benzene, toluene, xylene and manganese in soil and

groundwater, although the source of these contaminants most likely remains

to be a former petroleum storage tank farm located off Site to the west.

Figure 1.2, enclosed, identifies the underground gasoline tank and the

petroleum storage tank farm.

3.1 SITE PREPARATION

Site preparation included all activities necessary to

prepare the Site prior to commencing the excavation activities. The Site

preparation activities were carried out in accordance with those activities

outlined in the RA Plan and are described below.

3.1.1 Maintenance Building and Fence Removal

Between the period March 23, 1992 to March 26, 1992, prior

to excavating the chemical fill and contaminated soil, the maintenance

building and fence were removed and relocated. This work did not involve

contact with potentially contaminated chemical fil l and/or soils and was

conducted under the supervision of the City of Charles City. During this

activity, the surface casings for monitoring wells MW8 and MW8A were cut

off at ground surface to allow the building to be moved. The surface casings

were subsequently repaired in July 1992 during the installation of new

monitoring well MW19.

Following removal of the building, the City of Charles

City erected a snow fence around the area to be excavated. The fence was

maintained throughout the remedial action excavation and backfilling

activities, and was secured at the end of each day. The fence was posted with a

combination of signs which bore the legend "Danger - Hazardous Waste",

"Notice Authorized Personnel Only", "Danger, Keep Out", "Respirator

12

Required". The signs were visible from all approaches to the excavation area.

The area within the fence was designated as an Exclusion Zone during

chemical fill and contaminated soil excavation activities as discussed in the

Health and Safety Plan (HASP) presented as Appendix G to the RA Plan.

3.1.2 Floor Slab Removal

On April 1, 1992 and April 2, 1992, the maintenance

building's concrete floor slab was excavated by Allied Construction and was

disposed of as construction rubble at the Shaw Avenue Site. Portions of the

maintenance building's concrete footings were also excavated and disposed of

as construction rubble at the Shaw Avenue Site. The concrete floor slab and

the portions of the footings disposed of at the Shaw Avenue Site were

visually determined by Mr. Neil Leipzig (SAH) not to be in contact with the

chemical fill. Photographs were taken to document that the concrete floor

slab and portions of the footings were not in contact with the chemical fill

(see Appendix A). However, portions of concrete footing were also visually

determined to be in contact with the chemical fill and were left in place to be

excavated by CWM and disposed of with contaminated soils off-Site, at a

CWM authorized RCRA landfill (see Section 3.6).

3.1.3 Existing and Construction Utilities

On April 9, 1992, the overhead power line in the vicinity

of OU1 (see Plan 1) was removed by the utility company. On April 10,1992,

13

the underground gas line in the vicinity of OU1 (see Plan 1) was purged by the

gas company and the line was capped north and south of the area identified to

be excavated.

On April 13, 1992, telephone services were connected to

the office trailer, and on April 15, 1992, electrical services were connected to

the office trailer and personnel hygiene/emergency medical trailer. All

services were run above ground.

3.1.4 Personnel Support and Hygiene Facilities

On April 13 and 15, 1992, Chemical Waste Management,

Inc. (CWM), the RA Contractor, mobilized equipment and personnel support

and hygiene facilities to the Site. These included an office trailer and

personnel hygiene facility/emergency medical facility and separate tankage

for potable water and wastewater as specified in the RA Plan. The personnel

hygiene/emergency medical facility was classified as a Contaminant

Reduction Zone and the office trailer was classified as a Support Zone as

discussed in the HASP presented as Appendix G to the RA Plan. Office space

for U.S. EPA and IDNR officials was also made available at the WWTP.

3.1.5 Access Road

On April 15,1992, CWM constructed a haul road on Site to

allow for vehicle access to the excavation area. The access road was located to

14

the west of the identified chemical fill area, and was constructed using road

rock.

Also on April 15, 1992, CWM stripped all asphalt and

topsoil to a depth of approximately one foot off the area to be excavated. The

asphalt and topsoil were disposed of in piles at the south end of the Shaw

Avenue Site. It was subsequently determined (see Section 3.2) that the soils

were contaminated above performance standards and they were excavated

from the Shaw Avenue Site and disposed of off Site at a CWM authorized

RCRA landfill (see Section 3.6).

3.2 EXCAVATION AND REMOVAL

The chemical fill, contaminated soil and underground

storage tank were excavated by CWM using a track-mounted hydraulic

backhoe with a toothless bucket. Excavation commenced on April 16, 1992

and was completed on May 7, 1992. During excavation activities, precipitation

which accumulated in the excavation was allowed to either recharge into the

underlying bedrock, as approved by the U.S. EPA, or was pumped out of the

excavation into an on-Site wastewater holding tank.

Excavated materials were visibly classified and segregated

at the point-of-excavation as chemical fill, contaminated soil or contaminated

debris/soil and disposed of accordingly (see Section 3.6).

15

Excavation of the chemical fill and contaminated soil

extended vertically from the ground surface to the top of bedrock. Where

bedrock was encountered, the bedrock surface was scraped by the backhoe and

the scrapings disposed of with the chemical fill and/or contaminated soil, as

appropriate. Excavation of the chemical fill and contaminated soil initially

extended horizontally a minimum of two feet beyond the limit of the

chemical fill. Due to the distinctive appearance of the chemical fill, the point

of contact between the chemical fill and soil was determined visually in the

field.

Confirmation soil sampling was conducted, as discussed

in Section 3.3, to determine if the performance standard for total arsenic had

been met. If the concentration of total arsenic for a confirmation sample from

a specific sampling location was found to be in exceedance of its performance

standard, additional soil was excavated from that location until the

performance standard for total arsenic was achieved (see Section 4.0).

On April 29, 1992, Mr. Ed Roberts (CRA) contacted

Mr. Paul Roemerman (EPA) to discuss excavation procedures. It was agreed

to that soils for the upper and middle thirds of the sidewall which met the

performance standard for arsenic, based on confirmation analyses, could be

stockpiled in the excavation in areas from which chemical fill had been

already removed, to allow excavation of the soil third(s) that still exceeded the

performance standard for arsenic.

During excavation of the chemical fill it was noted that

the three piles of topsoil stripped from the excavation area and disposed of at

16

the Shaw Avenue Site (see Section 3.1.5) generated a yellowish leachate

following precipitation. A composite confirmation soil sample was collected

from the three piles on May 1,1992 and was analyzed by SAH for total arsenic.

The total arsenic concentration for the composite sample was 142 ppm.

Therefore, the three piles were all assumed to be contaminated above the

performance standard of 50 ppm for arsenic and were excavated and disposed

of off Site at a CWM authorized RCRA landfill (see Section 3.6). Native soils

underlying the three piles were also excavated to a depth of approximately

six inches. Following removal of the native soils, one discrete soil sample

was collected from beneath the center of each pile. The soils were submitted

for confirmation and verification analyses, all of which resulted in

concentrations significantly less than the performance standards (see

Section 4.0).

Plan 2, enclosed, delineates the final horizontal extent of

chemical fill and contaminated soil excavation. Plan 3, enclosed, presents

cross-sections of the excavation. Based on the cross-sections, an approximate

total volume of 2,220 cubic yards of chemical fill and contaminated soil were

excavated and treated and/or disposed off Site at a CWM authorized RCRA

landfill.

On April 21,1992, the underground gasoline storage tank

was excavated during excavation of the chemical fill and soil. Following

excavation, the tank was scraped to remove any remaining soil on the

exterior. The tank did not have any residual liquid product however, some

petroleum vapor was present as indicated by air monitoring. Subsequently,

carbon monoxide was added to lower the lower explosive level from

17

40 percent to 0 percent. Ultimately the tank was disposed of as scrap metal by

the City of Charles City at Dale's Automotive Inc., 1100 13th Avenue,

Charles City, Iowa.

Sampling around the underground storage tank was

conducted in accordance with the State of Iowa and federal underground

storage tank regulations. Pursuant to Iowa Code Chapter 135.9(3), one soil

sample was collected from soil beneath the center of the tank. The sample

was analyzed by National Environmental Testing, Inc. of Cedar Falls, Iowa for

Total Hydrocarbons (TH), quantified as gasoline, using Iowa Method OA-1.

The concentration of TH in the soil beneath the center of the storage tank was

110 ppm (see Appendix E) which is in exceedance of Iowa's Department of

Natural Resources allowable level of 100 ppm. However, as part of the

chemical fill and soil excavation activities, all the soils beneath and within

3 feet of the tank were excavated to the top of bedrock and were disposed of off

Site at a CWM authorized RCRA landfill (see Section 3.6).

3.3 CONFIRMATION/VERIFICATION SAMPLING

Confirmation and verification samples were collected

during excavation activities in accordance with the protocols discussed in the

Field Sampling Plan (RA Plan, Appendix D), with two exceptions, as

discussed below.

On April 30, 1992, Mr. Ed Roberts (CRA) contacted

Mr. Paul Roemerman (EPA). It was agreed to amend the sidewall sampling

18

procedure for the north end of the excavation due to excessive height of the

sidewall. Samples in this area of the excavation were collected remotely by

the backhoe with a special sample attachment (stainless steel tube attached to

side of backhoe bucket).

Confirmation and verification sampling for chemical fill

and contaminated soil was conducted at approximately 14-foot intervals along

the perimeter of the excavation as specified in the RA Plan. Three discrete

samples were collected along the sidewall of the excavation from depths of

1/3, 2/3 and at the base of the excavation and were submitted to SAH's

laboratory. However, the confirmation samples were not composited as

specified in the RA Plan, but were analyzed discretely. SAH then split the

discrete samples, with one half used as a confirmation sample to screen for

total arsenic. When it was determined that the confirmation sample had met

the performance standard for total arsenic, the second half of the split discrete

sample was then prepared by SAH and sent to Wadsworth Alert Laboratories

(WAL) of North Canton, Ohio, for verification analysis. Final verification

samples were analyzed for total arsenic and total cadmium (see Section 4.0) in

accordance with CLP protocols.

Exploratory test pits were excavated adjacent to areas that

persisted in exceeding the cleanup standard to provide a more expedient

delineation of soils in order to meet the May 8, 1992 deadline. The areas that

persisted in exceeding the cleanup standard were as follows: 009, 010, Oil, 012

and 013. Results of these test pit excavations are discussed in Section 4.2.

Confirmation and verification soil samples were also

collected from the base of three topsoil piles excavated from the Shaw

Avenue Site (see Section 3.2) and from the fill and topsoil backfilled in the

excavation (see Section 3.7). All these additional samples were determined to

be significantly below the performance standards for total arsenic and total

cadmium (see Section 4.0).

Table 3.2 presents a summary of all confirmation samples

and corresponding verification samples collected. As shown in Table 3.2, not

all confirmation samples have corresponding verification samples. As

discussed above, verification samples were only prepared by SAH when the

confirmation sample was determined to meet the performance standard for

total arsenic. Plan 2 shows the locations of all verification samples.

Section 4.0 presents the confirmation and verification soil

sample results. Appendix B presents chain-of-custody forms documenting

confirmation samples collected by CRA personnel and verification samples

prepared by SAH.

Note:

(*) Analyzed for TH as gasoline

activities. During all chemical fill excavation activities, machine operators

were in Level B personnel protective equipment (PPE) during active

excavation. During most soil excavation activities, machine operators were

in Level C PPE. On May 1,1992, after all the chemical fill had been excavated

and removed from the Site, machine operator PPE was downgraded to

modified Level D as discussed and agreed to between Mr. Ed Roberts (CRA)

and Mr. Paul Roemerman (EPA). All sample collection activities and

decontamination of equipment was performed by personnel in Level C PPE.

3.4.2 Air Monitoring

Air monitoring for organic vapors was performed during

the excavation of the chemical fill and surrounding contaminated soil using a

photoionization detector (PID). Monitoring of organic vapors commenced

with excavation activities and was performed at a minimum of one-hour

intervals during active excavation. Air monitoring was performed at a

minimum, immediately upwind of the excavation, at the point of excavation

of and immediately downwind of the excavation. Appendix H presents a

summary of PID readings.

In addition to the PID monitoring, draeger tube samples

for benzene and trichloroethene were also collected on April 15, 1992 and

April 16,1992. The draeger tubes exhibited negative results for benzene and

less than 1.0 ppm for trichloroethene. Appendix H presents a summary of

draeger tube results.

21

Direct real time monitoring was also performed for total

dusts using Sibata dust meters. Monitoring commenced with excavation

activities and was performed at a minimum of one-hour intervals during

active excavation. Measurements were taken upwind of the excavation and

loading activities, directly at the excavation face, and downwind of the

excavation and loading activities. During excavation, the chemical fill

exhibited moist conditions, as such, the potential for dust emissions during

chemical fill excavation was severely limited as shown by the monitoring

results. Appendix H presents a summary of Sibata Dust Readings.

3.5 OFF-SITE TRANSPORTATION

An EPA hazardous waste generator identification number

IAD000677872 had historically been obtained for the Site by the City of Charles

City. The generator ID number was used on all of the manifests forms for

hazardous waste shipped from the Site. Prior to shipment of any hazardous

wastes from the Site, authorizations for disposal were obtained from the

receiving disposal facilities. Also, the states for which the hazardous waste

would be transported to for ultimate disposal were notified. Copies of

agreements for disposal and State notifications are presented in Appendix B

of the RA Plan.

All excavated hazardous material designated for off-Site

disposal were labeled and manifested prior to leaving the Site. The manifest

forms and records were consistent with federal and applicable regulations.

22

Completed copies of the manifest forms for all hazardous materials

transported from the Site are presented in Appendix J.

A weatherproof tarp was provided and secured over each

shipment leaving the Site. All shipments were in compliance with applicable

RCRA and Department of Transportation (DOT) requirements for shipment

of hazardous waste. All trucks were weighed at SAH's DOT-approved scale,

located at 1900 Rockford Road, Charles City, Iowa or at the Cowell

Co-operative scale located off of llth Street, Charles City, Iowa.

3.6 OFF-SITE TREATMENT AND/OR DISPOSAL

A treatability study of the chemical fill and contaminated

soil was performed by CWM (RA Plan, Appendix D). It was found that only

the chemical fill required treatment. Fixation/stabilization of the chemical

fill by best practical means was accomplished by adding Portland cement to

the chemical fill in the ratio of 0.5:1.0. CWM's Treatability Study determined

that fixation/stabilization with Portland cement will virtually eliminate

leaching of the contaminants from the solidified matrix. Treatment and

disposal of the chemical fill was authorized and conducted at the CWM

Emelle Facility, Emelle, Alabama.

Contaminated soil did not require any treatment since the

leaching rate of contaminants out of the soil (as established by the CWM

Treatability Study) was minimal. The contaminated soil was authorized for

disposal at the CWM, CID Facility, Calumet City, Illinois.

23

CWM provided all notices required by the appropriate

state environmental authorities for disposal. Copies of the required notices

are provided in Appendix B of the RA Plan. Copies of completed manifest

forms for all hazardous materials treated and/or disposed of off Site are

presented in Appendix J.

Table 3.3 summarizes chemical fill removed from the Site

and treated and disposed of at the CWM, Emelle facility, and Table 3.4

summarizes contaminated soils and Rl-generated waste removed from the

Site and disposed of at the CWM, CID facility.

Table 3.3 shows a total of 56 truckloads of chemical fill

with a total weight of 1,267.47 tons were transported, treated and disposed of

at the CWM, Emelle facility. Table 3.4 shows a total of 113 truckloads of soil

and Rl-generated wastes, with a total weight of 2,624.31 tons were transported

and disposed of at the CWM, CID facility.

3.7 BACKFILLING

Once the identified chemical fill and contaminated soil

was excavated, loaded and transported to the designated approved RCRA

landfills, the excavation was backfilled with clean (sand) fill. The source of

the fill was the same as that chemically analyzed and subsequently used by

Solvay Animal Health in 1990 in closing its RCRA surface impoundment.

The fill material was free of logs, stumps, construction debris, etc. A chemical

analysis of the fill was previously submitted to the U.S. EPA, a copy of which

is included in Appendix G. The quantity of clean (sand) fill imported was

3,219.10 tons. The sand fill was placed in 12-inch lifts and compacted to a

minimum 90% of Standard Proctor Density. Appendix G provides a

summary of the clean fill compaction results. A sample of the sand fill was

also collected for confirmation and verification analyses (see Section 4.0 ).

The final six inches of the backfilled material was clean

topsoil with a vegetated cover or road rock. The topsoil was fertile loamy

material free from stones and clods over two inches in diameter, roots,

vegetation, weeds, and other debris. Road rock was placed in excavated areas

of the adjacent access road to the Shaw Avenue Site. A total of 734.80 tons of

topsoil and 49.80 tons of road rock were placed. A sample of the topsoil was

also collected for confirmation and verification analyses (see Section 4.0).

Table 3.5 provides a summary of quantities of materials

used for backfill.

3.8 DECONTAMINATION

The excavation equipment used allowed removal of the

contaminated material while remaining outside of the excavated area. As a

result, only the backhoe bucket and portions of the boom came in contact

with contaminated material. As necessary during excavation operations, the

backhoe bucket and affected boom were cleaned with a high pressure low

volume steam cleaner. Steam cleaning took place directly over a loaded

transport vehicle in order that all contaminated fluids were captured. The

volume of rinse water was effectively contained in the lined truck and

disposed of with the excavated material at the appropriate off-Site CWM

hazardous waste facility.

Contaminated material was excavated by backhoe, and

loaded directly into prepared vehicles for transportation to the appropriate

CWM RCRA landfill. A temporary pad (10-mil plastic sheeting) was

provided between the backhoe and transport vehicle during loading to collect

any spillage of chemical fill or contaminated soil.

Prior to loaded trucks leaving the Site, they were visually

inspected for potential contact with the chemical fill or contaminated soil

outside the truck's lined box. Decontamination of any affected portions of the

truck were performed by scraping and/or brushing any chemical fill or

contaminated soil onto the 10-mil plastic sheeting. The plastic sheeting was

then disposed of with the waste material.

3.9 ENVIRONMENTAL CONTROLS

3.9.1 Surface Water Control

During excavation activities significant precipitation

occurred during the period of April 16, 1992 to April 21, 1992. The working

face of the excavation was covered during work stoppages to prevent

precipitation contact with potentially contaminated soils and surface water

26

runoff was prevented from entering excavations by using dikes and ditching,

as necessary, around the perimeter of the excavation diverting runoff away

from the excavation. However, significant precipitation accumulated in the

base of the excavation. The precipitation was initially allowed to infiltrate

into the underlying bedrock with the approval of the U.S. EPA. However,

precipitation accumulation became too significant to perform excavation

activities. On April 20, 1992, and April 21, 1992, two samples of accumulated

precipitation in the excavation were collected for total arsenic,

orthonitroaniline and 1,1,2-trichloroethane analysis by SAH. The two

samples exhibited total arsenic concentrations of 26.4 ppm and 15.8 ppm;

orthonitroaniline concentrations of 64.7 ppm and 46.3 ppm and did not detect

1,1,2-trichloroethane at a detection level of 0.005 ppm. Based on the

concentration of constituents in the accumulated precipitation and the fact

that excavation could not be carried out in the dry, all accumulated

precipitation was pumped out of the excavation and collected in the on-Site

wastewater holding tank for off-Site treatment at the CWM facility in

Newark, New Jersey (see Section 3.10.1).

3.9.2 Dust Control

Due to the moist conditions experienced during

excavation operations and based on the Sibata Dust readings, dust control

measures were not required to be implemented.

27

3.9.3 Sediment Control

Sediment migration was not a concern during the

excavation of chemical fill and contaminated soil since any storm water that

may have potentially contacted these materials was contained within the

excavation.

3.9.4 General Housekeeping

Daily accumulations of solid waste material such as debris

and rubbish was collected in garbage bags and disposed of as sanitary waste.

Personnel protective equipment (PPE) which contacted chemical fill and/or

potentially contaminated soils were disposed of as debris with the

contaminated soils at the CWM, CID Facility.

The Site was not allowed to become littered with general

non-ha2ardous refuse and/or waste materials from the working areas, but

was maintained in a neat and orderly condition throughout the excavation

period.

3.10 PROTECT CLOSEOUT

All closeout activities were coordinated and performed in

such a manner that no waste materials scheduled for off-Site disposal or

mobilized facilities remained at the Site upon completion of this program.

28

Any temporary pads were disposed off Site by CWM with the contaminated

soils and debris.

As discussed previously in Section 3.7, the excavations

were backfilled with approved clean fill, topsoiled and seeded.

3.10.1 Stored Wastewater Removal

Stored wastewaters were characterized in accordance with

State and Federal regulations. The characterization analyses of the liquid

contents determined the appropriate method of disposal. A total of

2,944 gallons of liquid waste was transferred from the on-Site holding tank to

a liquid waste transportable tanker and treated/disposed of at the CWM

facility in Newark, New Jersey. Following emptying of the wastewater tank,

the tank interior was decontaminated with a high-pressure water wash

supplemented by detergent (Alconox). Decontamination wastewater

generated was also collected in the tanker.

A copy of the waste profile sheet and approval letter for

treatment of the wastewater at the CWM facility in Newark, New Jersey is

included in Appendix I. A copy of the manifest form for the shipment of

wastewaters is included in Appendix J.

29

3.10.2 Investigation Derived Waste Disposal

A total of 115 drums of RI generated material (soils and

PPE) were stored at the Shaw Avenue Site. All drums were inspected at the

Site prior to shipment and were characterized as either contaminated soil or

debris. The drummed waste materials were disposed of off Site at the CWM,

CID Facility.

Consolidation of the drums was performed at the Site

prior to off-Site shipment of the wastes. All the drums were transferred to

the excavation area and were placed in the open excavation on top of the

exposed rock. The drums and contents were then crushed using the backhoe

bucket. The crushed drums and contents were then loaded onto transport

vehicles for off-Site transport and disposal. Copies of the manifest forms for

the shipment of the RA-generated wastes are included in Appendix J.

3.10.3 Final Cleanup

Final cleanup involved cleaning the Site of litter and

trash resulting from the work and left the Site in a neat and orderly

condition. Litter and trash resulting from the work was disposed of at the

local sanitary landfill.

4.0 SOIL ANALYSIS RESULTS

This section presents the analytical results for the

confirmation and verification sampling conducted in accordance with the

approved RA activities for OU1.

As discussed in Section 3.3, confirmation of verification

sampling protocols were carried out according to the Field Sampling Plan (RA

Plan, Appendix D). Analytical protocols for confirmation and verification

samples were carried out according to the Quality Assurance Project Plan (RA

Plan, Appendix E).

4.1 DATA QUALITY ASSESSMENT AND VALIDATION

All analytical results provided by Wadsworth/Alert

Laboratories (WAL) were assessed for data quality and validation in

accordance with approved methods. Provided in Appendix F are copies of the

Data Quality Assessment and Validation reports. All data was found to be

acceptable with the limited qualifiers listed in the reports.

4.2 CONFIRMATION/VERIFICATION RESULTS

Confirmation/verification sampling in the area of OU1

was conducted as described in Section 3.3. Samples were collected by CRA,

confirmation analyses were performed by SAH and verification analyses

31

performed by Wadsworth/Alert Laboratories in North Canton, Ohio (WAL).

The confirmation samples were analyzed for total arsenic and the verification

samples were analyzed for total arsenic and total cadmium. Confirmation

and verification laboratory data reports are presented in Appendix E.

Arsenic analytical results for the confirmation analyses

are summarized in Table 4.1. Confirmation and verification analyses are

summarized in Table 4.2. Table 4.2 provides the confirmation sample

identification number, the corresponding verification sample identification

number, the sample location, and the analytical results. As shown on

Table 4.2 there was a good correlation between SAH and WAL detected

concentrations for arsenic. Total arsenic results are reported in both dry

weight and wet weight concentrations. The analytical methods utilized

determine the dry weight arsenic concentration. In order to calculate the wet

weight arsenic concentration, the dry weight concentration is multiplied by

the percent solids of the specific sample. The wet weight concentration is

used to determine if the performance standard for total arsenic was met since

the wet weight represents the in situ arsenic concentration of the soil. The

verification sample results and locations are shown on Plan 2, enclosed.

Verification cadmium analytical results are not

summarized on Tables 4.1 and 4.2 because cadmium was not detected, at a

detection limit of 1.0 ppm, in all samples. The performance standard for total

cadmium is 20 ppm.

As shown on Table 4.2, the total arsenic concentrations

(wet weight) for all verification samples are below the performance standard

of 50 ppm with one exception. One verification result for total arsenic was

found to be in exceedance of the performance standard of 50 ppm. The

concentration was 59.2 ppm at sample location 9A. SAH's confirmation

result for total arsenic at the same location was 46.4 ppm.

Exploratory test pits were excavated to expedite the
