MEMORANDUM

SUBJECT: ACTION MEMORANDUM — Request for Emergency Removal Actions at the Galen Myers Site, Osceola, Joseph County, Indiana (Site ID #05R4)

FROM: Mike Beslow, OSC Emergency Response Section 4

THRU: Sam Borries, Chief Emergency Response Branch 2

TO: Douglas Ballotti, Acting Director Superfund Division

I. PURPOSE

This memorandum documents the decision and verbal approval to initiate an emergency response action described herein for the Galen Myers Vapor Intrusion Site (Galen Myers Site, or the Site) in Osceola, Indiana and a ceiling amount not to exceed $248,135.

The response actions proposed herein were necessary in order to mitigate threats to public health, welfare, and the environment posed by the presence of uncontrolled hazardous substances at the site. EPA documented trichloroethene (TCE) at the site; which is a hazardous substance as defined by section 101(14) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Future response actions proposed herein may be necessary in order to mitigate additional threats to public health, welfare, and the environment posed by the presence of uncontrolled hazardous substances at the site.

The removal actions herein mitigate immediate threats to public health, welfare, and the environment posed by the presence of elevated levels of volatile organic compounds (VOCs) in the indoor air of residential properties resulting from vapor intrusion; perform vapor mitigation, as necessary; and transport and dispose off-site any hazardous substances, pollutants and contaminants at a CERCLA-approved disposal facility in accordance with EPA's Off-Site Rule (40 CFR § 300.440).

Response actions have been and will continue to be conducted in accordance with Section 104(a)(1) of CERCLA, 42 U.S. Code (USC) § 9604(a)(1), to abate or eliminate the immediate threat posed to public health and/or the environment by the presence of the hazardous substances

at the site. The uncontrolled conditions of the hazardous substances present at the site and the potential threats they present require that this action be classified as an emergency response action. EPA's completed actions to date took approximately 5 working days to complete and expect additional actions to take up to 13 working days.

Potentially responsible parties (PRP) information is included in the attached Confidential Enforcement Addendum (Attachment IV).

This site is currently listed on the National Priorities List.

II. SITE CONDITIONS AND BACKGROUND

CERCLIS ID: IND980999635 RCRA ID: none Category: Time-Critical Removal Action

A. Site Description

1. Removal Site Evaluation

EPA conducted site assessment beginning in April 2016 as part of their remedial actions. Activities included the sampling and motioring of ground water, soil gas, sub-slab, and indoor air. The following sections summarize that information.

Figure 1 is a site location map. Figure 2 and Figure 3 are site maps, identifying the site homes identified for testing.

a. St. Joseph County Health Department

On June 24, 2016, St. Joseph County Health Department (SJCHD) made a request for action in 7 homes that exceeded Removal Management Levels for TCE. EPA installed 6 vapor intrusion mitigation systems the week of Aug 15, 2016 and installed the seventh on October 12, 2016. Initially the seventh homeowner chose not have it installed, but later changed their mind. EPA expects a request for up to an additional 13 homes to receive mitigation systems based on remedial sampling.

b. PRP Facilities

From the 1970's until 1983, the site was a former drum salvage and dump operation where drums filled with various solid and liquid chemical waste materials were emptied to the ground and the empty drums were sold for reuse. The chemicals, including TCE and other chlorinated solvents (types of VOCs) entered the underground water.

c. EPA

The following sections describe EPA's assessment activities.

2

Historic Response:

In 1981, SJCHD investigated the Galen Myers property in response to nearby residents' allegations of dumping and unauthorized storage of potentially hazardous materials. The SJCHD inspectors observed dumping and storage activities at the site property and requested Myers to cease such operations and filed a complaint with the ISBH (Indiana State Board of Health) Land Pollution Control Division.

ISBH inspected the site in April 1983 and observed drummed solid and liquid wastes scattered throughout the property and requested that EPA conduct a site inspection. EPA conducted a site investigation in June 1983. Galen Myers passed away before EPA could question him further regarding the contents of the drums and his disposal methodologies. The Myers family indicated that the drum disposal business ceased operation and they intended to dispose of the drums and other debris. Disposal activities did not occur and ISBH conducted another site inspection in April 1984. The site property appeared to be abandoned, and due to the condition of the drums on the property, ISBH requested EPA reevaluate the site for a potential removal action. Based upon results from a second site investigation conducted in June 1984, EPA determined that the site posed a direct and indirect threat to human health and the environment and warranted a removal action.

In November 1984, EPA authorized a removal action at the site and conducted it from February to April 1985. Wastes disposed under this removal action included 1,800 pounds of flammable solids, 30 cubic yards of nonhazardous crushed drums, and 56 cubic yards of nonhazardous soils. Drums claimed by potentially responsible parties were removed by May 1985. Residential well samples collected from the site property and adjacent wells indicated traces of VOCs at concentrations that were below EPA Removal Action Levels. Therefore, groundwater was not addressed during the 1985 removal action.

In late 1986 to 1987, Indiana Department of Environmental Management(IDEM) collected soil samples from the site property and residential well samples. In February 1987, IDEM notified EPA that the analytical results indicated that site soils were still significantly contaminated with organic chemicals and downgradient residential wells were contaminated with TCE at unsafe levels. IDEM requested that EPA participate in a joint sampling program to delineate the groundwater plume and provide an alternative drinking water supply for the affected residents.

In spring 1987, IDEM sampled 15 residential wells and EPA sampled 13 residential wells. Results of the joint residential well sampling program delineated a plume of contamination that was about 148 feet wide and 2,638 feet long. The affected wells were located in the direction of groundwater flow directly south of the site property along the west side of Birch Road. To mitigate the threat of TCE contamination to the affected residents, EPA installed air stripper/granulated activated carbon filter units at two residences, whole house carbon filtration units at three residences, and point-of-use carbon filters at three residences. EPA placed the Galen Myers site on the NPL in March 1989.

3

From January 1991 to February 1994, IDEM conducted residential well sampling to monitor TCE levels. The maximum TCE concentration found was 10,932 lag/L. During this time period an additional 21 residential wells were found to be contaminated with TCE. IDEM installed six point-of-use filter systems and 15 whole-house filter systems at the affected residences. At this time, IDEM was monitoring a total of 29 residential water filtration units. In May 1993, IDEM requested that EPA consider the Galen Myers site for an emergency removal action to expedite a permanent solution for the residents who had water filtration units and others that could be potentially exposed through migration of TCE in groundwater. In January 1994, EPA approved a second removal action to construct a waterline extension from Mishawaka Utilities to the affected area. By June 1996, EPA had provided municipal water to approximately 180 residences that responded to the offer to be supplied with city water.

Initially, 24 homeowners declined to be hooked up to the municipal water supply (see Figure 2); however, five of these residences are now connected to municipal water.

June 2015 and December 2015

In June 2015 and December 2015, EPA's Remedial program conducted soil gas monitoring in and around the area where the groundwater plume has been deteanined to be. The results yielded areas of concern for vapor intrusion, and the Remedial program followed up with indoor air and sub-slab sampling.

April 2016

In April 2016, EPA's Remedial program conducted indoor air and subslab sampling at the properties of concern.

2. Physical Location

The site is a Residential Area bounded by the St. Joseph River to the south, Birch Road to the east, Hartford Bay Drive to the north, and RainTree Drive to the west in Osceola, St. Joseph County, Indiana.

EPA conducted an Environmental Justice (EJ) analysis for the site (see Attachment I). Screening of the surrounding area used Region 5's EJ Screen Tool. Region 5 has reviewed environmental and demographic data for the area surrounding the Galen Myers Site, and detemfined there is not a high potential for EJ concerns at this location.

3. Site Characteristics

The Site consists of a plume of contaminated groundwater, soil gas and indoor air in a mixed residential neighborhood in Osceola, St. Joseph County, Indiana.

EPA's urgent and accelerated response actions were based on site specific recommendations from ATSDR and their citing of the July 9, 2014 Memorandum: EPA Region 9 Action Levels

4

and Recommendations to Address Near-Teiiii Inhalation Exposures to TCE in Air from Subsurface Vapor Instrusion.

EPA Region 9 Interim TCE Indoor Air Response Action Levels- Residential and CommercialTCE Inhalation Exposure from Vapor Intrusion

Exposure Scenario Accelerated Response Action Level (HQ=1)

Urgent Response Action Level (HQ=3)4

Residential * 2 ig/m3 6 Jig/m3 Commercial/Industrial * (8-hour workday)

8 Jig/m3 24 1.1.g/m3

Commercial/Industrial * (10-hour workday)

7 j.ig/m3 21 Rim'

• The residential HQ=accelerated response action levels equivalent to the inhalation reference concentration (RfC) since exposure is assumed to occur continuously. ** Commercial/Industrial accelerated response action levels are calculated as a time-weighted average from the RfC, based on the length of a workday and rounding to one significant digit (e.g., for an 8-hour workday: Accelerated Response Action Level = (168 hours per week/40 hours per week) x 2 Jig/m3 = 8 Jig/m3). Time- weighted adjustments can be made as needed for workplaces with longer work schedules. Note: Indoor air TCE exposures corresponding to these accelerated response action levels would pose cancer risks near the lower end of the Superfund target cancer risk range, considering the IRIS toxicity assessment; thus, the health protective risk range for both accelerated response actions and long-term exposures becomes truncated to: .0.5- 2 Jig/m3 for

residential exposures and 3 -8 µg/m3 for 8-hour/day commercial/industrial exposures.

At least 44 properties were sampled by the Remedial program and their site assessment results found indoor air TCE concentrations as high as 1 Oug/m3. There were seven exceedences of 2 Jig/m3 and additional unvalidaded data shows that there are at least two additional exceedences of 2 Jig/m3. Additional properties continue to be sampled by the remedial program.

4. Release or threatened release into the environment of a hazardous substance, or pollutant or contaminant

EPA documented a release of hazardous substances, pollutants, or contaminants in indoor air at seven residences and in soil gas. EPA has taken the following mitigation measures to reduce the contaminants of indoor air: Installation of 7 vapor mitigation units in affected homes. Continued monitoring indoor air for the presence of identified constituants.

Hazardous substances were present in soil gases, below the subslabs of the identified homes, and in indoor air completing the vapor intrusion pathway. Possible exposure routes include inhalation of contaminated through subsurface soil and groundwater, i.e. vapor intrusion. Potential human receptors include residents in the Residential Area.

EPA's remedial program continues to sample additional homes they have identified. EPA expects that mitigation systems may be needed in up to 20 homes total, 13 in addition to the 7 homes that have already received mitigation systems.

B. Other Actions to Date

1. Previous actions

Previous actions are detailed in Section II, A, 1, Removal Site Evaluation.

2. Current actions

There is an ongoing remedial action being conducted by the EPA. Indiana Department of Environmental Management (IDEM) is conducting groundwater monitoring of the neighborhood. SJHD is in consultation with ATSDR regarding health factors surrounding the site.

C. State and Local Authorities' Roles

On June 23, 2016, Luis Galup, SJDH's Health officer requested assistance from EPA.

III. THREATS TO PUBLIC HEALTH OR WELFARE OR THE ENVIRONMENT, AND STATUTORY AND REGULATORY AUTHORITIES

The conditions at the Galen Myers Site present a threat to the public health or welfare, and the environment, and meet the criteria for a time-critical removal action as provided for in the NCP, 40 CFR 300.415(b)(2). These criteria include, but are not limited to, the following:

Actual or potential exposure to nearby human populations, animals, or the food chain from hazardous substances or pollutants or contaminants;

EPA documented the presence of TCE in indoor at concentrations above ATSDR's recommended response levels of 2 p g/m3 for an accelerated response and 6 µg/m3for an urgent response in a residential home. TCE was detected in indoor air in homes at up to 10 pg/m3.

Possible exposure routes include inhalation of contaminated air that may have migrated through subsurface soil and groundwater, i.e. vapor intrusion. Potential human receptors include residents in the Residential Area.

6

TCE is a hazardous substance within the meaning of Section 101(14) of CERCLA because it is listed at 40 C.F.R. § 302.4. Historical groundwater sampling, and EPA sub-slab and indoor air sampling results indicate that TCE vapors are migrating into residential structures at levels above the accelerated response level of 2 jig/m3. TCE is a man-made chemical that is widely used as a cleaner to remove grease from metal parts. TCE is a nonflammable, colorless liquid with a sweet odor.

ATSDR has studied toxicological effects of TCE and associated chemicals, and inforniation is provided below and detailed in the Administrative Record (Attachment I).

Trichloroethylene: Breathing small amounts of TCE may cause headaches, lung irritation, dizziness, poor coordination, and difficulty concentrating. Breathing large amounts of TCE may cause impaired heart function, unconsciousness, and death. Breathing it for long periods may cause nerve, kidney, and liver damage. Drinking large amounts of TCE may cause nausea, liver damage, unconsciousness, impaired heart function, or death. Drinking small amounts of TCE for long periods may cause liver and kidney damage, impaired immune system function, and impaired fetal development in pregnant women, although the extent of some of these effects is not yet clear. Skin contact with TCE for short periods may cause skin rashes. Some studies of people exposed over long periods to high levels of TCE in drinking water or in workplace air have found evidence of increased cancer. In its 9th Report on Carcinogens, the National Toxicology Program (NTP) determined that trichloroethylene is "reasonably anticipated to be a human carcinogen." The International Agency for Research on Cancer (IARC) has determined that trichloroethylene is "probably carcinogenic to humans."

The availability of other appropriate federal or state response mechanisms to respond to the release;

SJCHD requested EPA assistance in mitigating the threat of exposure to TCE in residential indoor air. On June 23, 2016, Luis Galup, SJCHD Health officer sent a letter to EPA formally requesting assistance.

IV. ENDANGERMENT DETERMINATION

Given the site conditions, the nature of the known and suspected hazardous substances on site, and the potential exposure pathways described in Sections II and III above, actual or threatened releases of hazardous substances from this site, if not addressed by implementing the response actions selected in this Memorandum, may present an imminent and substantial endangerment to public health, welfare, or the environment.

V. PROPOSED ACTIONS

A. Proposed Actions

1. Proposed action description

7

The response actions described in this memorandum directly address actual or potential releases of hazardous substances on site, which may pose an imminent and substantial endangerment to public health, or welfare, or the environment. Removal activities will include:

1. Performing vapor mitigation at properties where relevant indoor air action levels are exceeded in accordance with current EPA guidance;

a. On August 18th, 2016 EPA completed the installation of vapor intrusion mitigation systems at 6 different homes.

b. On October 12, 2016 EPA completed the installation of vapor intrusion mitigation system on a 7th home.

c. Installing mitigation systems on up to 13 additional homes.

2. Performing post-installation proficiency sampling 30 days and 6 months after mitigation system installation;

The removal actions will be conducted in a manner not inconsistent with the NCP. EPA will initiate planning for provision of post-removal site control consistent with the provisions of NCP § 300.415(1).

The threats posed by uncontrolled substances considered hazardous meet the criteria listed in NCP § 300.415(b)(2), and the response actions proposed herein are consistent with any long-term remedial actions which may be required.

EPA did collect signed Operation and Maintenance (O&M) agreements prior to installation of a vapor mitigation systems. The O&M agreement states that the property owner will provide electricity to power the vapor abatement system in-line fan. Installation of individual vapor mitigation systems were contingent upon the property owner signing this agreement. The vapor abatement system in-line fan is warrantied by the installer for 5 years following installation. If needed, O&M, of the vapor abatement systems will be the responsibility of the property owner following installation and performance monitoring by EPA per the signed agreement.

Off-Site Rule

All hazardous substances, pollutants, or contaminants removed off-site pursuant to this removal action for treatment, storage, and disposal shall be treated, stored, or disposed of at a facility in compliance, as determined by EPA, with the EPA Off-Site Rule, 40 C.F.R. § 300.440.

2. Contribution to remedial performance

The actions will contribute to the efficient performance of any long-term remedial action with respect to the observed release based on information from EPA's Site Assessment Program. Due to the imminent and substantial threat of TCE, the indoor air was addressed immediately in conjuction with the ongoing remedial work. The time-critical removal actions are consistent with a permanent remedy.

3. Engineering Evaluation/Cost Analysis (EE/CA)

Not Applicable

4. Applicable or relevant and appropriate requirements (ARAR)

On June 28, 2016, EPA's OSC Beslow sent a letter requesting ARARs to IDEM. EPA did comply with ARARs to the extent practicable.

B. Removal Project Ceiling Estimate — Extramural Costs:

Regional Removal Allowance Costs: Total Cleanup Contractor Costs (Includes a 20% contingency)

Other Extramural Costs Not Funded from the Regional Allowance

Total START, including multiplier costs Subtotal, Extramural Costs

Extramural Costs Contingency (20% of Subtotal, Extramural Costs)

TOTAL REMOVAL ACTION PROJECT CEILING

$145,974

$60,805 $206,779

$41,355

$248,135

The response actions described in this memorandum directly address the actual or threatened release of hazardous substances, pollutants, or contaminants at the site which may pose an imminent and substantial endangerment to public health or welfare or to the environment. These response actions do not impose a burden on affected property disproportionate to the extent to which that property contributes to the conditions being addressed.

VI. EXPECTED CHANGE IN THE SITUATION SHOULD ACTION BE DELAYED OR NOT TAKEN

Given the site conditions, the nature of the hazardous substances and pollutants or contaminants documented on site, and the potential exposure pathways to nearby populations described in Section II, HI, IV, and V above, actual or threatened releases of hazardous substances and pollutants or contaminants from this site, if not addressed by implementing or delaying the response actions selected in this Action Memorandum, may present an imminent and substantial endangerment to public health, welfare, or the environment, increasing the potential that hazardous substances will be released, thereby threatening the adjacent population and the environment.

Delayed action may increase residents' exposure to hazardous substances.

9

VII. OUTSTANDING POLICY ISSUES

None.

VIII. ENFORCEMENT

For administrative purposes, information concerning the enforcement strategy for this Site is contained in the Enforcement Confidential Addendum.

The total EPA costs of this removal action based on full-cost accounting practices that will be eligible for cost recovery are estimated to be $248,1351.

($248,135+ $30,000) + (61.96% X $278,135) = $450,468

IX. RECOMMENDATION

This decision document represents the selected removal actions for the Galen Myers Site located in Osceola, St. Joseph County, Indiana, developed in accordance with CERCLA, as amended, and is not inconsistent with the NCP. This decision is based upon the Administrative Record for the site. Conditions at the site meet the NCP § 300.415(b)(2) criteria for a time-critical removal action.

The total removal action project ceiling, if approved, will be $248,135. Of this, as much as $145,974 may be used for cleanup contractor costs. You may indicate your decision by signing below.

APPROVE Ddugla Ballotti, Acting Director Superfund Division

DISAPPROVE DATE: Douglas Ballotti, Acting Director Superfund Division

1 Direct Costs include direct extramural costs and direct intramural costs. Indirect costs are calculated based on an estimated indirect cost rate expressed as a percentage of site specific direct costs, consistent with the full cost accounting methodology effective October 2, 2000. These estimates do not include pre-judgement interest, do not take into account other enforcement costs, including Department of Justice costs, and may be adjusted during the course of a removal action. The estimates are for illustrative purposes only and their use is not intended to create any rights for responsible parties. Neither the lack of a total cost estimate nor deviation of actual total costs from this estimate will affect the United States right to cost recovery.
