Steven R. Novick, Chief RE: NEW BEDFORD Emergency Response & Removal Re lease Tracking Number 4-00\5685 USEPA Region I Parker Street Waste Site 5 Post Office Square Property P-O 11 Boston, Massachusetts 02109-3912

Dear Mr. Novick:

As you arc aware, on April 26, 2010, the United Stales Environmental Protection Agency (USEPA). in coordination with the Massachusetts Department of Envi ronmental Protection (MassDEP), began field

implementation of a Sampling and Analysis Plan (the SAP), dated April 2010, to dctcnn ine if contaminants of concern (COes) associated with the Parker Street Waste Site (PSWS) were present on

approx imately 63 land parcels compris ing 47 private ly owned properties in the vicinity of the PSWS.

The SAP was prepared jointly by the USEPA, MassDEP, Roux Associates, Inc. and E2 Inc. c/o Citizen's

Leading Environmental Action Network and Weston Solutions.

As described in the SAP, the USEPA, MassDEP and thcir env ironmental contractors collected soil samples from borings instal led at the 63 parcels and submitted the soil samples for analysis at fixed

laboratories. The so il samples were analyzed fo r COCs typically associated with the PSWS, including

polych lorinated biphenyls (PCBs), polycycl ic aromatic hydrocarbons (PAHs), arsenic, barium, cadmium,

chromium and lead. Soi l borings were advanced to a depth approximately 12 feet be low ground surface (bgs). The following vertical horizons were analyzed: 0 - I ' bgs, 1- 3 ' bgs, and 3 - 12' bgs.

As the SAP analytical results from ind ividual properties are received from the laboratory and validated,

MassDEP and its Site Assessment Remediation Support Services (SARSS) contractor MACTEC have

been performing evaluations of the data to delennine whether remed ial action is required under the

MassDEP Waste Site Cleanup requirements contained in 310 CMR 40.0000, the Massachusetts

Contingency Plan (the MCP). The MCP establishes numerical and perfonnance standards for addressing releases of oil andlor hazardous materials to the envi ronment. On August 19, 20 10, MassDEP requested

USEPA assistance to address properties where an Imminent Hazard may exist andlor where concentrations in the top th ree feet of soil exceeded the applicable MCP category S-1 soil standards,

meaning a Condition of No Significant Risk did not exist. Th is request was made based on the

information available at the time and was fOllowed-up with specific risk characterizations by property for the purpose of typology chart development and risk communication with property owners.

Enclosed is a copy of the results from the risk evaluation conducted by MACTEC for the property identified as P-Ol l. These results are the basis for MassDEP' s communication with you regarding typology chart development for this property. This evaluation compared the sample results from the soil samples collected from the 7 boring locations on this property to the MCP category S-I soil standards and to either potential Imminent Hazard values listed in the MCP or site-specific Imminent Hazard (IH)

values. Given that each property was evaluated separately, and because additiona l sampling was not planned as part of this effort, both the average concentration and the 95% upper confidence limit of the average concentration (95% VCL) ofCOCs detected for each depth zone (0-1 ft. bgs, 0-3 ft. bgs and >3 ft. bgs) were evaluated. The 95% UCL provides an added measure of conservatism that can be used when evaluating data from a limited data set. If either thc average concentration or the 95% VCL for a given depth zone exceeded the applicable S-I soil standard or IH value, then the communication was made, for the purpose of developing the typology chart for the property, that an IH existed and/or a Condition of No Significant Risk did not exist. For property P-O 11, MassDEP provided you the following determinations:

An Imminent Hazard condition, as defined in the MCP. was detennined to exist for the current use of the property for the top 1 foot of soil. Specifically, lead was detected in soil boring P-OII-SB-04 in the top foot of soil at concentrations greater than or equal to the site-specific Imminent Hazard levels established by MassDEP for this Site . The MCP requires elimination or control of all Imminent Hazards. This may be accomplished by removing the top foot of soil in the vic inity of these soil borings and replacing it with clean soil or it can be accomplished by otherwise covering those areas with clean soil or an impervious surface or cap. No activities should occur on thi s property that will disrupt the top foot of soil until removal or cover measures are complete.

A condition of No Significant Risk. as defined in the MCP, was detennined not to exist fo r current use of the property for the soil located between the ground surface and 3 feet in depth. Specifically, concentrations of PAHs and/or lead were detected in samples collected from the top three 3 feet in soil borings P-O II-SB-02 and P-OII-SB -04 above the applicable Mep S-I soil standards. The MCP requires actions to be taken to address this condition, which may include removal of this layer of soi l in the vicinity of these soil borings and replacing it with clean soil or covering those areas in this layer of soil with an appropriate cap material. No activities should occur at the property that will disrupt soil located from the ground surface to a depth of3 feet until removal or cover measures are complete.

Furthennore, a condition of No Significant Risk, as defined in the MCP, for foreseeable future use of the property has not been detennined to exist for the soil located between 3 feet and 12 feet below the ground surface. This is because concentrations of PAHs and/or lead were detected above the applicable MCP S- I soil standard in the soil borings identified as P-Oll-SB-03 and P-Oll-SB-04 in samples collected from a depth greater than 3 feet. Because this soil is at depth, it does not necessarily need to be removed to be protective of the current use of the property. MassDEP and MACTEC are perfonning a more in-depth risk evaluation of the sample data from greater than 3 feet in depth from this property to better dctennine whether the presence of these contaminants at these levels and depths in these limited areas constitute a Condition of No Significant Risk. This additional evaluation includes reviewing the avai lable data for this specific property along with data from adjacent parcels to confirm whether or not a Condition of No

P-oU Page 3 of 4

Significant Risk exists. By increasing the data set being evaluated, it is possible that the 95% UCL can be eliminated from consideration for decision-making. Until MassDEP completes this eva luation, soi l below 3 feet should not be disturbed on this property unless it is under the direction and supervision of a Licensed Site Professiona l, and in consultation with MassDEP.

Given the findings above, MassDEP has verified that its previous request for USEPA assistance on this property was appropriate. MassDEP continues to evaluate the SAP data on both a property-specific basis and by evaluating data from adjacent parce ls to refine its risk evaluations to be able to more specifically inform USEPA of the level of assistance required for other properties.

USEPA has informed MassDEP that the determinations and request provided in thi s letter will be used for response action decision-making as the USEPA works with the Potentially Responsible Parties, MassDEP and landowners in planning and conducting appropriate removal actions to address contamination in the zero to 1 foot, and I to 3 foot soil layers. MassDEP will continue to coordinate with USEPA throughout the response action alternative review process and will also work with the Potentially Responsible Parties

and land owners to address conditions assoc iated with contamination present at a depth greater than 3 feet below the ground surface.

The information and determinations contained herein are based solely on review of the data available from SAP implementation and do not apply to any other actions or aspects of the PSWS not reviewed as part of the SAP. Additional sampling or inclusion of existing sample data generated by others as part of the risk evaluations could impact or refine the findings of the risk-based analysis performed by MassDEP and MACTEC. Additionally, as stated above, MassDEP and MACTEC are performing more in-depth risk evaluation and SAP data analysis for this property and surrounding properties intended to refine the information we provide to USEPA for response action decision-making.

MassDEP's findings do not preclude future audits and/or review of past, current, or future actions related to the PSWS nor do they in any way constitute a release from any liability, obl igation, action or penalty under M.G.L. c. 21 E, 310 CMR 40.0000, or any other law, regulation, or requirement. Finally, these findin gs do not limit MassDEP's authority to take or arrange, or to require any Responsible Party or Potentially Responsible Party to perform, any response action authorized by M.G.L. c. 21 E which MassDEP deems necessary to protect health, safety, public we lfare, or the environment

Please fee l free to contact me at the letterhead address, or by ca ll ing 508.946.2708 if you have any questions related to the infonnation provided herein. MassDE P appreciates the opportunity to collaborate with you on this important effort.
