Section 1 Introduction 1.1 Release History On behalf of 47 Center Street, LLC, Tighe & Bond has prepared this Class A-2 Response Action Outcome (RAO) Statement, including an Immediate Response Action (IRA) and Phase IV Completion statement to document the historical release and subsequent closure of a No. 2 fuel oil release from a former underground storage tank (UST) at 47 Center Street, Northampton, Hampshire County, Massachusetts (the site). A subsurface release of No. 2 fuel oil was discovered at the site during the removal of a 1,000 gallon fuel oil UST on August 28, 2000. In response to the release, 44 tons of petroleum impacted soils were excavated, disposed off site and four groundwater monitoring wells were installed at the site by Cold Spring Environmental Consultants, Inc. (CSEC). CSEC submitted an IRA plan to the Massachusetts Department of Environmental Protection (MA DEP) on January 24, 2001 recommending the installation of additional groundwater monitoring wells at the site. Environmental Compliance Services, Inc. (ECS) of Agawam, Massachusetts was contracted by the former site owner in July 2001. Between August 2001 and January 2003, ECS installed eight additional groundwater monitoring wells and one groundwater extraction well at the site. Light non-aqueous phase liquid (LNAPL) was detected in six wells at the site. Between January 2001 and January 2006, ECS conducted bail and gauge activities at the site and removed a total of 19 gallons of an LNAPL/groundwater mixture from groundwater monitoring wells. ECS submitted a Phase I Initial Site Investigation report to MA DEP in August 2001, a Phase II Scope of Work in September 2001, a Phase II Comprehensive Site Assessment Report and Phase III Remedial Action Plan in September 2005. Exceedences of applicable Method 1 Groundwater Cleanup Standards for extractable petroleum hydrocarbons (EPH) and/or target polycyclic aromatic hydrocarbons (PAHs) were detected in site groundwater during a sampling event in January 2003 by ECS. Exceedences of applicable Method 1 Soil Cleanup Standards for volatile petroleum hydrocarbons (VPH) were also identified at the site. This sampling was performed using bailers. On December 1, 2006 Tighe & Bond submitted a change of LSP letter to the MA DEP, thereby changing the LSP-of-record for the site from Virginia Irvine of ECS to Tighe & Bond. On May 18, 2007, Tighe & Bond submitted an IRA Status Report for the site. IRA activities summarized in the report included the replacement of an additional downgradient groundwater monitoring well (MW-13), installation of two soil borings (B-1 and B-2 for soil observations), installation of additional groundwater monitoring wells at the site, LNAPL gauging and groundwater sample collection. In July 2007, Tighe & Bond submitted a Phase IV Remedy Implementation Plan (RIP) for the site. The Phase IV RIP proposed the implementation of in-situ chemical oxidation (ISCO) as an appropriate remedial technology for the site to help reduce LNAPL Section 1 Introduction Tighe&Bond Response Action Outcome Statement RTN 1-13601 1-2 thickness. More specifically, the injection of a catalyzed mixture of peroxide and sodium persulfate was proposed as an appropriate Comprehensive Remedial Action (CRA) to help remove or reduce the LNAPL at the site. As discussed herein, prior to chemical injections, all wells sampled via low flow sampling since 2005 did not contain petroleum compounds above applicable GW-2 and GW-3 standards and still contained vaying thickness of LNAPL. On January 21, 2008, Tighe & Bond submitted an IRA Status and Phase IV Status Report for the site. IRA and Phase IV activities summarized in the status report include LNAPL gauging and removal activities and ISCO injection activities. On May 19, 2008, Tighe & Bond submitted an IRA Status Report for the site. IRA and Phase IV activities summarized in the report included the results of multiple rounds of LNAPL gauging/removal and the results of one comprehensive round of low-flow groundwater sampling. On April 9, 2008, groundwater samples were collected from multiple monitoring wells throughout the site. Groundwater analytical results identified temporary elevated EPH concentrations in two monitoring wells (MW-7 & MW-10) at concentrations above applicable GW-2/GW-3 cleanup standards. As discussed herein, concentrations in these two wells further stabilized to below GW-2 and GW-3 standards (pre injection conditions). 1.2 Conceptual Site Model The site is located in an urban/downtown area of Northampton, Massachusetts, and is the location of a former Masonic Lodge, containing one brick building that is currently not occupied. The City of Northampton municipal water supply provides drinking water to the site and to surrounding properties. Surface water bodies are not located at, or in close proximity to, the subject site. One 1,000 gallon No. 2 fuel oil UST was removed from the site on August 28, 2000. The UST was removed from the northeastern corner of the site and provided fuel to the boiler located in the basement of the building. Documents prepared by CSEC, who observed removal of the UST, indicated that petroleum impacted soil and groundwater were observed in the tank grave when the UST was removed. Observations at the time of UST removal indicate that the UST system failed, resulting in a historical release of No. 2 fuel oil to the subsurface. The volume of fuel oil released at the site is unknown. Fuel oil is currently provided to the basement boiler via a 330 gallon aboveground storage tank located in the basement boiler room. The former UST was located adjacent to the building foundation in the northeast corner of the site. Soil conditions observed throughout the site are generally very fine sand, silt and clay. Gauging data collected from monitoring wells throughout the site indicate that groundwater is between approximately five and eight feet below surface grade. LNAPL has been identified in exterior and interior monitoring wells installed through the basement concrete slab of the building. Groundwater at the site is approximately eight to 12 inches below the top of the basement concrete slab and five to eight feet below surface grade. All portions of the site in the vicinity of the former UST are paved. Nuisance odors have not been identified at the site. Points of exposure to site contaminants include potential indoor air impacts at the site building. Exposure to contaminated soil and groundwater Section 1 Introduction Tighe&Bond Response Action Outcome Statement RTN 1-13601 1-3 at the site is not likely and would only occur in the event of direct exposure to subsurface soil and/or groundwater (e.g. excavation). 1.3 Site Hydrology and Geology 1.3.1 Topography and Drainage The site is paved and is generally flat. Stormwater at the site flows to the north, toward the grass area at the 2-4 Center Court residential property or toward the south and into the Center Street roadway where catch basins are located. 1.3.2 Surficial Geology and Soils Surficial soils at the site generally consist of very fine sand and silt with varying amounts of clay. Groundwater at the site has been identified between five and eight feet below surface grade. Boring logs for subsurface work conducted by Tighe & Bond in 2007 are provided in Appendix C. 1.3.3 Bedrock Geology Bedrock has not been encountered during assessment activities performed at the site. 1.3.4 Groundwater Flow Direction Based on Figure 3 contained in previous reports prepared by ECS, the calculated groundwater flow direction is to the northeast. 1.4 Surrounding Resource Areas The site is located within a Non-Potential Drinking Water Source Area. The Mill River is located approximately 2,000 feet west of the site. NHESP Priority Habitats for Rare Wildlife and NHESP Estimated Habitats for Rare Wildlife are located approximately 1,800 feet west of the site. A Potentially Productive Medium Yield Aquifer is located approximately 2,500 feet east of the site. Protected and Recreational Open Space is located approximately 700 feet south, 2,000 feet south southwest, 1,300 feet east, and 1,800 feet northeast of the site. No surface water bodies are located at, or adjacent to, the site. A MA DEP Priority Resource Area map is provided as Figure 2 in Appendix B. 1.5 Groundwater and Soil Classification Groundwater and soils at disposal sites are characterized for risk characterization purposes based upon location and uses of the site and site groundwater. Specific Method 1 Standards have been developed for both soil and groundwater based upon these uses and the potential for human and environmental exposure. Groundwater and soil category classification criteria are set forth in 310 CMR 40.0932 and 40.0933, respectively, and are summarized here for applicability to the site. Three groundwater classifications have been developed by the MA DEP with respect to the following criteria, as outlined in the MCP: GW-1: GW-1 Standards apply within current or potential drinking water source areas, which include areas such as public water supply Zone II areas, undeveloped but Potentially Productive Aquifers (PPAs), and areas within 500 feet of a private drinking water well. GW-1 is not applicable to the site. Section 1 Introduction Tighe&Bond Response Action Outcome Statement RTN 1-13601 1-4 GW-2: GW-2 Standards apply to groundwater considered to be a potential source of vapors to indoor air. GW-2 is defined as groundwater that is within 15 feet of the ground surface and within 30 feet of an occupied structure. GW-2 is applicable to the site. GW-3: GW-3 applies to all groundwater in Massachusetts, based on its potential to discharge to surface water. Therefore, GW-3 is also applicable to the site. Soils at a site are classified based upon the potential for human exposure. These potentials are based upon children’s and adults’ frequency of use of the area (high, low or not present), the intensity of the use (high or low) and the accessibility of the soils (accessible, potentially accessible or isolated). These criteria are listed in 310 CMR 40.0933(4) and are used to define exposure potentials for the three soil classifications developed by DEP. Based on the applicability of each of these criteria, soils are classified as S-1, S-2 or S-3. Category S-1 soil represents soil with the greatest exposure potential while category S-3 represents soil with the least exposure potential. Based on the known activities at the site (high frequency and low intensity use by adults and children), the depth of residual impacted soil at the site and because the site is paved, site soil is categorized as S-2. 2SECTION 2 Tighe&Bond Response Action Outcome Statement RTN 1-13601 2-1 Section 2 Summary of Remediation and Site Assessment Activities 2.1 Site Remediation Activities 2.1.1 Soil Excavation A total of 44 tons of petroleum impacted soils was removed from the UST area by CSEC following the August 28, 2000 UST removal. 2.1.2 Soil & Groundwater Treatment On October 23 & 24, 2007, Redox Tech, LLC of Attleboro, Massachusetts was onsite to perform ISCO remedial injection activities. Approximately 5,250 gallons of water and sodium persulfate slurry were injected into 17 injection points throughout the release area. A total of 15,400 pounds of sodium persulfate was injected at the site. 2.2 Soil Boring Advancement A total of 20 soil borings have been advanced at the site since August 2000 to evaluate soil and groundwater conditions in the vicinity of the former UST. Seventeen of the soil borings have been completed as groundwater monitoring wells. Soil borings have been advanced using both hollow stem auger drilling methodology and direct push methods. Soil boring and monitoring well locations are shown on the Figure 3 Site Plan in Appendix A. Soil borings were advanced to a maximum of 23 feet below surface grade. Multiple soil samples were collected from each soil boring. Select soil samples were screened in the field for the presence of volatile organic compounds (VOCs) using a photoionization detector (PID). 2.2.1 Soil Conditions Three soil borings were advanced at the site by Tighe & Bond. Soil borings B-1, B-2 and monitoring well MW-13 were advanced on May 30, 2007. Soil boring locations are shown on the Figure 3 Site Plan in Appendix B. Soil boring MW-13 was completed as a two inch groundwater monitoring well with a ten foot screened interval set to intersect the observed groundwater table. Under the observation of a Tighe & Bond Environmental Scientist, each of the three borings was advanced using 4.25 inch hollow stem auger drilling methodology. Soil samples were collected from each boring. Soil borings B-1 and B-2 were advanced near the former UST. Soil boring MW-13 was advanced southeast of the former UST, across the Center Court roadway. Boring logs from B-1, B-2 and MW-13 are included in Appendix C. Soil boring B-1 was advanced to 19 feet below surface grade and soil samples were collected continuously from five to 19 feet below surface grade. In general, soil conditions encountered in B-1 were brown to grey silt and clay. Groundwater was identified in B-1 at approximately 8.5 feet below surface grade. No overt evidence of oil saturated soil was observed in this boring. At the time B-1 was advanced, the adjacent monitoring well MW-1 was gauged and found to contain 8 inches of fuel oil. Section 2 Summary of Remediation and Site Assessment Activities Tighe&Bond Response Action Outcome Statement RTN 1-13601 2-2 Soil boring B-2 was advanced to 14 feet below surface grade and soil samples were collected continuously from ten feet to 14 feet below surface grade. In general, soil conditions encountered in B-2 were brown silt and clay. Groundwater was identified in B-2 at approximately ten feet below surface grade. No overt evidence of oil saturated soil was observed in this boring. Soil boring MW-13 was advanced to 22 feet below surface grade and soil samples were collected in five foot intervals from the ground surface to 22 feet below surface grade. In general sand and urban fill were encountered to approximately seven feet below surface grade and brown to grey silt and clay were encountered from ten to 22 feet below surface grade. Groundwater was identified in MW-13 at approximately 12 feet below surface grade. Soil boring MW-13 was completed as a groundwater monitoring well. No overt evidence of oil saturated soil was observed in this boring. Boring logs documenting borings B-1, B-2 and MW-13 are included in Appendix C. 2.3 Monitoring Well Installation Seventeen groundwater monitoring wells have been installed as part of assessment and remediation activities performed at the site since August 2000. Three monitoring wells have been installed through the interior basement concrete slab. Thirteen viable groundwater monitoring points currently remain at the site. 2.4 Soil Sampling CSEC collected a total of five soil samples from the limits of the UST excavation for laboratory analysis in September 2000. ECS advanced multiple soil borings and installed several groundwater monitoring wells at the site between December 2000 and January 2003. ECS submitted a total of seventeen soil samples for laboratory analysis. 2.5 Groundwater Sampling CSEC collected groundwater samples from the site on December 28, 2000. ECS collected groundwater samples from the site on January 27, 2003 and July 12, 2005. Following the October 2007 remedial injection, Tighe & Bond collected groundwater samples from the site on April 9, 2008, September 25, 2008 and March 25, 2011. The groundwater monitoring wells sampled during these sampling events are identified below: April 9, 2008: EW-1, MW-6, MW-7 & MW-9 September 25, 2008: MW-7 & MW-10 March 25, 2011: EW-1, MW-6, MW-7, MW-8D, MW-9D & MW-10 Each groundwater sample was collected in general conformance with Environmental Protection Agency (EPA) approved low-flow/low-stress groundwater sampling methodology. Groundwater samples were submitted to Test America Laboratory of Westfield, Massachusetts (TAL) for extractable petroleum hydrocarbon (EPH) and/or volatile petroleum hydrocarbon (VPH) analyses. Section 2 Summary of Remediation and Site Assessment Activities Tighe&Bond Response Action Outcome Statement RTN 1-13601 2-3 2.6 Surface Water and Sediment Sampling Surface water bodies are not located at or adjacent to the site. Neither surface water nor sediment samples have been collected from the site. 2.7 Soil Gas/Indoor Air Sampling Soil gas and indoor air samples were collected from the site on March 25, 2011. One sub-slab soil gas sample, identified as SG-1, was collected in the site building from below the concrete basement slab. One indoor air sample, identified as IA-1, was collected within the building basement. 2.8 Management of Remediation Waste Petroleum impacted soils were excavated from the site on August 28, 2000 during the removal of the 1,000 gallon fuel oil UST. Forty-four tons of petroleum impacted soils were excavated and transported off site for proper disposal. LNAPL removal activities performed at the site to date have generated approximately 25 gallons of a LNAPL and groundwater mixture. LNAPL and groundwater removed from site monitoring wells has been stored in a steel 55 gallon drum in a plastic overpack. The drum was transported off site for proper disposal in March 2011. 3SECTION 3 Tighe&Bond Response Action Outcome Statement RTN 1-13601 3-1 Section 3 Nature and Extent of Release 3.1 Soil Analytical Results 3.1.1 Excavation Confirmatory Sample Results Five confirmatory soil samples, identified as E-Side-6’, Bot-E 9.5’, Bot-W 10.0, NW-Cor, and SE-Cor, were collected from the UST grave by CSEC as part of the August 2000 UST removal. Each soil sample was submitted to a state certified laboratory for EPH analysis. Soil sample analytical results are summarized Table 1 in Appendix B. As indicated in Table 1, concentrations of EPH carbon fractions and EPH target analytes were not detected above laboratory reporting limits in soil samples E-Side-6’, Bot-E 9.5’ or Bot-W 10.0. Concentrations of EPH carbon fractions, 2-methylnaphthalene and phenanthrene were detected above laboratory reporting limits, but significantly below Method 1 S-1/GW-2 and S-2/GW-2 cleanup standards, in soil samples NW-Cor and SE- Cor. 3.1.2 Soil Boring Sample Results Seventeen soil samples were collected for laboratory analysis from 15 soil borings advanced at the site. Soil samples were submitted to a state certified laboratory for EPH and/or volatile petroleum hydrocarbon (VPH) analysis. Soil sample analytical results are summarized in Table 1 in Appendix B. As indicated in Table 1, concentrations of EPH and/or VPH constituents were identified above laboratory reporting limits in soil samples MW-4 (10’-12’), MW-6 (10’-12’), MW-10 (0-2’), SB-1 (5’-10’), SB-1 (7.5’-10’) and SB-3 (6.5’). Moreover, concentrations of petroleum constituents were detected above Method 1 S-1/GW-2 cleanup standards in soil samples MW-10 (0-2’) and SB-1 (7.5’-10’). More specifically, concentrations of C9-C10 aromatic hydrocarbons were detected in soil sample MW-10 (0-2’) at 120 mg/kg, above the Method 1 S-1/GW-2 cleanup standard of 100 mg/kg. Concentrations of naphthalene were detected in soil sample SB-1 (7.5’-10’) at 450 mg/kg, above the Method 1 S-1/GW-2 and S-2/GW-2 cleanup standard of 40 mg/kg. With the exception of the two exceedances detailed above, positive detections of petroleum constituents in soil were below the Method 1 S-1/GW-2 and S-2/GW-2 cleanup standards. 3.2 Groundwater Analytical Results Following the October 23 and 24, 2007 remedial injection, Tighe & Bond collected groundwater samples from the site on April 9, 2008, September 25, 2008 and March 25, 2011. Each groundwater sample was collected in general conformance with EPA low- flow/low-stress groundwater sampling methodology and submitted to TAL for analysis. Groundwater samples were submitted to TAL for EPH and/or VPH analysis. Groundwater analytical results are summarized in Table 2 in Appendix B. As shown in Table 2, wells MW-7 and MW-10 were the only wells that displayed a temporary increase in contaminant concentrations above applicable standards following the chemical injection events. Wells MW-7 and MW-10 have since stabilized to pre- injection conditions and are currently below applicable Method 1 standards. All other remaining groundwater monitoring wells display contaminant concentrations below applicable Method 1 standards. Section 3 Nature and Extent of Release Tighe&Bond Response Action Outcome Statement RTN 1-13601 3-2 3.3 Surface Water and Sediment Analytical Results Neither surface water nor sediment is located at, or within close proximity to, the subject site. Neither surface water nor sediment has been sampled as part of assessment activities performed at the site. 3.4 Soil Gas/Indoor Air Analytical Results One soil gas sample and one indoor air sample have been collected from the site. On March 25, 2011, one soil gas sample, identified as SG-1, was collected from below the basement concrete slab of the site building and one indoor air sample, identified as IA-1, was collected from within the basement. Soil gas sample SG-1 was collected over a 30 minute interval. Indoor air sample IA-1 was collected over an eight hour interval. Each soil gas and indoor air sample was collected in a laboratory-supplied six liter SUMMA canister and submitted to Con-Test Analytical Laboratory (Con-Test) of East Longmeadow, Massachusetts for air petroleum hydrocarbons (APH) analysis. A copy of Con-Test laboratory report number 11C0885 is included in Appendix B. Soil gas and indoor air analytical results are summarized in Table 3 in Appendix B. Within Table 3, soil gas results are compared to Method 2 Soil Gas Screening Levels for Evaluating Indoor Air Impacts and indoor air results are compared to MADEPs Residential Typical Indoor Air Concentrations. As indicated in Table 3, concentrations of APH were identified in the soil gas sample SG-1 that was well below the Method 2 soil gas screening levels. As indicated in Table 3, concentrations of APH were identified in the indoor air sample IA-1 that were below the indicated 75th and 90th percentile concentrations. Only the concentration of C5-C8 aliphatics was detected at above the 75th percentile concentrations but below the 90th percentile concentration. It should be noted that one 330 gallon above ground fuel oil storage tank is located in the basement and provides fuel to the boiler located in the basement. 3.5 LNAPL Light non-aqueous phase liquid (LNAPL) has been historically identified in several groundwater monitoring wells at the site. A summary of LNAPL gauging and recovery is included as Table 4 in Appendix B. As indicated in Table 4, approximately 41 LNAPL gauging and removal events have been conducted at the site. Within Table 4, wells with a measured LNAPL thickness greater than ½ inch following the October 2007 remedial injections are shaded. As part of each LNAPL gauging event, measurable amounts of LNAPL were removed from wells using either a bailer or a peristaltic pump with single-use polyethylene tubing. Oily groundwater/LNAPL removed from wells was stored on site in an over packed 55-gallon steel drum. As detailed in Table 4, a total of approximately 21.55 gallons of oily groundwater and LNAPL has been removed from site groundwater monitoring wells between December 29, 2000 and March 25, 2011. As detailed in Section 2.2, soil conditions encountered at the site generally consist of silt and clay to the maximum depth of boring advancement at the site, or 22 feet below surface grade. Silt and clay soils are generally defined by their very small grain size and, as a result, have more pore spaces and relatively high porosity. The small pore Section 3 Nature and Extent of Release Tighe&Bond Response Action Outcome Statement RTN 1-13601 3-3 spaces and high porosity of silts and clays result in increased surface tension, cohesion and adhesion of groundwater within the subsurface formations. As a result, groundwater does not easily flow or move through silts and clays and the specific yield of these formations are very low as compared to sand and gravel, resulting in very low permeability or hydraulic conductivity. The low permeability/hydraulic conductivity of the silt and clay formations at the site significantly decrease the mobility of groundwater and greatly reduce the migration potential of LNAPL at the site. As summarized in Table 4 in Appendix B, LNAPL thicknesses in many of the wells have varied significantly over the years of gauging. LNAPL thicknesses in the wells is a function of many parameters, including soil type, groundwater elevation, and well diameter. In general, as the well diameter decreases, LNAPL thicknesses in the well increase. Most wells are 1-inch diameter wells. The recovery well located within the former UST grave is a 4-inch diameter well and has largely not had measurable oil in the well. Soil types with finer grained silts/clays have much higher pore pressures than soils that contain more sands and gravel. Higher pore pressures will result in a greater volume of residual oil slowly accumulating in the wells. As groundwater elevations increase, LNAPL thickness will tend to decrease and as groundwater elevations decrease, LNAPL thicknesses in wells will tend to increase. These conditions have been observed at the site. It is generally recognized that in most subsurface soils, groundwater and LNAPL coexist in soil pores and any LNAPL present will displace some of the groundwater within the soil pores. The amount of LNAPL within soil pores generally decreases with depth until LNAPL is not present and groundwater is not displaced. When a monitoring well or bore hole penetrates the saturated zone, LNAPL and groundwater migrate into the well and the thickness of the LNAPL within the well is generally greater than the actual thickness of the oil in the aquifer. Because groundwater and LNAPL coexist in soil pores and groundwater remains in the soil pores, the amount of oil in the soil formation is significantly less than the measured LNAPL thickness in monitoring wells. The very low concentrations of petroleum constituents detected in site soils, summarized in Table 1 in Appendix B and observations of soil located adjacent to wells with LNAPL, provide further evidence that soils are not saturated with LNAPL, that groundwater and LNAPL coexist within soil pores at the site and that the measured thickness of LNAPL in site monitoring wells is not representative of soil conditions. It is evidenced by the gauging data that the LNAPL recovery performed over the years has gradually reduced LNAPL thickness in wells. But LNAPL is still detectable within site wells. The chemical injections were targeted to help reduce overall LNAPL concentrations. An average LNAPL thickness was calculated for all wells gauged from 2008 to current from wells that historically contained measurable LNAPL, including MW-3 as this well is located within the source area. The 2008 data to current were selected for the average as these data better represent stabilized groundwater conditions following the chemical injections that were performed. The calculated average was 0.59 inches, which is slightly above the MCP upper concentration limit (UCL) of LNAPL of 0.5 inches. Based on the information presented above, it is our opinion that the LNAPL levels measured in site monitoring wells is not representative of actual site conditions with the Section 3 Nature and Extent of Release Tighe&Bond Response Action Outcome Statement RTN 1-13601 3-4 soil formation with respect to true oil thickness and does not accurately represent the amount of LNAPL in soils at the site. There is not appropriate guidance for calculating LNAPL thickness for comparison to the UCL standard of 0.5 inches. Based on a relatively low average thickness calculated for the recent gauging event from 2008 to current, primarily small diameter one-inch diameter wells and silty/clay soils that don’t contain elevated petroleum concentrations or observable oil saturated soils, the true oil thickness with the soil formation is likely well below 0.5 inches. This is further supported by the 4-inch diameter well EW-1 that has an approximate average thickness of 0.18 inches for gauging data from 2005 to present. DEP is currently working on new guidance for LNAPL projects that does not focus on the 0.5-inch standards. Although current draft documents should not be cited or quoted, a draft approach circulated for comment included evaluating LNAPL sites with respect to mobility, source control, and future risk. The criteria was as follows: 1. Adequate data for mobility evaluation with respect to soil properties, LNAPL properties, and soil saturation. LNAPL recovery rates have been extremely low since release discovery. During the years of periodic well gauging, LNAPL was removed. Based on soil concentrations, soil types, and volume recovered, there is limited LNAPL volume in the subsurface that is recoverable and corresponding dissolved concentrations are below applicable standards. Therefore, based on data presented above, adequate data have been collected with respect to mobility evaluations. 2. Has source been eliminated or controlled: LNAPL migration – for this site, LNAPL is not migrating. Perimeter and downgradient wells have not seen increase in LNAPL since release discovery. Some residual LNAPL was temporality mobilized during chemical injections but this condition has since returned to pre-injection conditions. Groundwater contamination – for this site, groundwater concentrations are below GW-2 and GW-3 criteria. Vapor intrusion – for this site, vapor intrusion was demonstrated not to be occurring. 3. Does LNAPL pose future risk to public welfare or environment – for this site, LNAPL does not pose future risk to public or environment based on soil and groundwater concentrations. 4. Does LNAPL pose future risk to public safety or human health – for this site, LNAPL does not pose future risk to public safety or human health based on soil and groundwater concentrations. Therefore, based on the above draft criteria being met, a permanent solution Class Response Action Outcome (RAO) can be achieved. 4SECTION 4 Tighe&Bond Response Action Outcome Statement RTN 1-13601 4-1 Section 4 Risk Characterization In support of this RAO statement, the characterization of risk at the site has been evaluated in accordance with the Method 2/3 Risk. 4.1 Selection of Risk Characterization Method In accordance with the 310 CMR 40.0980, Method 2 may be used to characterize the risk of harm to health, public welfare, and the environment at disposal sites where site investigations conducted in accordance with the MCP have determined that the release of oil and/or hazardous material is limited to soil and/or groundwater. Because low-level concentrations of APH have been identified in soil gas and indoor air at the site, limited site-specific information has been used. For evaluation of soil contaminants, MADEP Method 3 Risk Assessment Short forms for residential exposure scenarios were used to evaluate risk to residual soil contaminants. 4.2 Determination of Applicable Standards As detailed in Section 1.5, groundwater categories GW-2 and GW-3 are applicable to the site. 4.3 Exposure Pathway Evaluation 4.3.1 Soil Laboratory analysis of soil samples collected from the site indicate that residual concentrations of petroleum constituents are present in subsurface soils at the site. Subsurface soil is a potential exposure pathway at the site. 4.3.2 Groundwater Laboratory analytical results from groundwater samples collected from the site on March 25, 2011 were below applicable GW-2 and GW-3 standards, indicating that residual concentrations of petroleum constituents are present in site groundwater. 4.3.3 Surface Water and Sediment No surface water bodies and/or sediments are located at the site and surface water and sediment have not been impacted by this historical release. Surface water is not considered a potential exposure pathway. 4.3.4 Soil Gas/Indoor Air Laboratory analysis of soil gas and indoor air samples collected from the site on March 25, 2011 indicate that residual concentrations of APH are preset in soil gas and indoor air at the site. Based on comparison of soil gas concentrations to Method 2 screening levels established by the DEP and indoor air concentrations that are consistent with typical residential indoor air concentrations, soil gas and indoor air are not considered potential exposure pathways. Section 4 Exposure Pathway Evaluation Tighe&Bond Response Action Outcome Statement RTN 1-13601 4-2 4.4 Identification of Exposure Point Concentrations Exposure Point Concentrations (EPCs) represent the concentration of oil and/or hazardous material to which a human or environmental receptor may come in contact. An exposure point may be defined as an area or zone of potential exposure, as well as a single discrete point. To remain conservative, soil EPCs were determined based on the maximum concentrations detected for each detected compound of concern (COC). COCs detected in soil include EPH and VPH carbon ranges, naphthalene, 2-methylnaphthalene, phenanthrene, fluoranthene, pyrene, ethylbenzene, xylenes (mixed isomers) and naphthalene. Groundwater EPCs were selected as the most recent groundwater sampling result for each monitoring well. Since pre injection groundwater conditions were also all below GW-2 and GW-3 standards (except earlier results from samples collected with bailers), using the most recent results is appropriate. Since wells MW-7 and MW-10 temporarily increased following chemical injections, these results are not considered representative of groundwater conditions and therefore not used as part of the EPC. Concentrations within these wells decreased to pre injection conditions. MW-8 (destroyed now, was only sampled once in 2003 with a bailer) is not representative of site conditions. As other wells sampled with a bailer that were subsequently resampled using low flow were below standards, the one result from MW-8 is therefore not considered representative of site conditions. 4.4.1 Soil Twenty-two discrete soil samples have been collected from the site for laboratory analysis between September 27, 2000 and January 27, 2003. Soil analytical results are summarized in Table 1 in Appendix B. As indicated in Table 1, soil samples were collected between five feet and 25 feet below surface grade. Concentrations of petroleum constituents have been detected above laboratory reporting limits in eight of the 22 soil samples submitted for analysis. Based on the maximum concentrations being used as the EPC, the residual soil contamination does not pose a risk to human health based on the results of the Method 3 Risk Assessment Short Form included in Appendix B. 4.4.2 Groundwater Seventeen groundwater monitoring wells have been installed and sampled at the site. Groundwater analytical results are summarized in Table 2 in Appendix B. As indicated in Table 2, dissolved concentrations of petroleum constituents temporarily increased in monitoring wells MW-7 and MW-10 following the October 2007 remedial injection. However, analytical results from the March 25, 2011 groundwater sampling event showed a stabilization of petroleum concentrations to pre-injection conditions. With the exception of MW-8 (as discussed above), representative groundwater concentrations are below applicable Method 1 GW-2 and GW-3 Cleanup Standards. 4.5 Characterization of Risk Harm 4.5.1 Human Health, Public Welfare and Environment Soil and groundwater EPCs are discussed above. Calculated soil EPCs do not pose a risk to human health based on the results of the Method 3 Risk Assessment Short Form. Section 4 Exposure Pathway Evaluation Tighe&Bond Response Action Outcome Statement RTN 1-13601 4-3 Representative groundwater concentrations are less than Method 1 GW-2 and GW-3 standards and therefore is an indicator of lack of exposure potential. No soil or groundwater concentrations exceed UCLs. LNAPL thicknesses within the soil formation are also less than the UCL of 0.5 inches. Based on these data, it is our opinion that a condition of No Significant Risk of harm to human health, public welfare and the environment exists at the site. 4.5.2 Public Safety No rusted or corroded drums or containers, open pits, lagoons, or dangerous structures are located at the site. No threats of fire or explosion, including the presence of explosive vapors resulting from a release of oil and/or hazardous materials are located at the site. No uncontained materials which exhibit the characteristics of corrosivity, reactivity or flammability are located at the site. Based on the information presented within this report, a condition of No Significant Risk of harm to public safety exists at the site. 4.6 Feasibility of Achieving Background The feasibility of achieving background was evaluated following Immediate Response Actions (IRAs) performed at the site. Background is defined as those levels of OHM that would exist in the absence of the disposal site. For the purposes of assessing the feasibility of achieving background, it is assumed that “background” concentrations of petroleum constituents at the site are non-detect. Residual petroleum concentrations are present in soil and groundwater at the site, including residual LNAPL. Due to the tight silty/clay soil formations, the only remediation strategy to fully remove any residual LNAPL in the subsurface is soil excavation, which would require excavation beneath the existing structure. In accordance with DEP Policy WSC-04-160, excavation beneath structures that may compromise the structural integrity are considered “infeasible”. 4.7 Representativeness Evaluation and Data Useability Assessment The project involved field screening of soil samples with a photoionization detector (PID), laboratory analysis of 22 soil samples, laboratory analysis of multiple rounds of groundwater samples, and the collection and analysis of one soil gas and one indoor air sample. Soil samples were analyzed for EPH and/or VPH. Groundwater samples were analyzed for metals, EPH and VPH. Soil gas and indoor air samples were analyzed for APH. Groundwater quality parameter measurements were collected from site monitoring wells. Sampling has been conducted at the site since 2000 and has been performed in compliance with MCP Data Quality Enhancement (DQE) protocols. The MCP Case Narratives and Analytical Method Report Certification Forms are included in the soil gas and indoor air and analytical reports provided in Appendix B. In accordance with the DQE protocols, the laboratory analytical reports were reviewed for compliance with the DQE policy. The laboratory reports indicate that the soil gas and indoor air analytical data included in this report meet all the requirements for “Presumptive Certainty” as described in Section 2.0 (a), (b), (c) and (d) of the DEP documents CAM VII, Quality Assurance and Quality Control Guidelines for the Acquisition and Reporting of Analytical Data. Based on a review of the data, field observations, and the laboratory MCP Case Narrative Section 4 Exposure Pathway Evaluation Tighe&Bond Response Action Outcome Statement RTN 1-13601 4-4 description, the data collected during cleanup and monitoring activities are commensurate with their intended use and meet the PARCCS (precession, accuracy, repetitiveness, completeness, comparability and sensitivity) criteria, recommended for specifying quality assurance goals by the MA DEP. Sampling protocols and results are discussed with respect to these criteria below. Precision: Precision is the degree to which a set of observations or measurements of the same property, usually obtained under similar conditions, conform to themselves. Precision may be quantifiably measured through analysis of duplicates, or as discussed in the Compendium of Analytical Methods (CAM), in lieu of field duplicates, sampling precision related to the non-homogeneity of the impacted matrix may be most appropriately addressed via the analysis of an adequate data set of samples using field screening techniques. Twenty-two discrete soil samples were collected from the site and screened in the field with a PID and submitted for laboratory analysis. In general, PID field screening results, visual and olfactory observations, and laboratory analytical results conform to each other. Multiple rounds of groundwater sampling were performed at the site and multiple groundwater samples were submitted for laboratory analysis. In general, concentrations of petroleum constituents in site groundwater have decreased over time. In general, the concentrations of petroleum constituents identified in site groundwater corroborate with soil field screening results, soil analytical results and field observations while collecting each groundwater sample. Accuracy: Accuracy is the degree of agreement of a measurement with an accepted reference or true value. QA/QC performance standards that were not met by the laboratory are discussed in the MCP Case Narratives provided in the analytical laboratory reports included in Appendix B. MCP regulatory standard criteria were specified for each report. According to the MCP Case Narrative in Con-Test analytical report number 11C0885 for soil gas and indoor air samples collected on March 25, 2011, continuous calibration did not meet method specifications and was biased on the high side for methyl tert-butyl ether (MTBE). Data validation is not affected since the sample result was “not detected” for MTBE. According to the MCP Case Narrative in TAL analytical report 360-32914-1 for groundwater samples collected on March 25, 2011, some laboratory reporting limits do not meet WSC- CAM-III method reporting limits. Benzo[g,h,i]perylene, n-Hexatriacontane, and Indeno[1,2,3-cd]pyrene failed the criteria low for the closing Continuous Calibration Verification (CCV), resulting in some reporting limits to be biased high. No other difficulties were encountered during the EPH analysis and all other quality control parameters were within acceptable limits. No QA/QC issues were identified. Representativeness: Representativeness expresses the degree to which data accurately and precisely represent a characteristic of a population, parameter variation, or environmental condition. Twenty-two discrete soil samples were collected from the site and screened in the field with a PID. Each soil samples was submitted for EPH and/or VPH laboratory analysis. In general, soil samples with higher PID field screening results exhibited elevated concentrations of petroleum constituents as compared to soil samples with lower PID field screening results. We can infer from this favorable comparison that the laboratory results are valid. Section 4 Exposure Pathway Evaluation Tighe&Bond Response Action Outcome Statement RTN 1-13601 4-5 Multiple rounds of groundwater sampling were performed at the site and multiple groundwater samples were submitted for laboratory analysis over an eleven year period. In general, concentrations of petroleum constituents in site groundwater have decreased or have been stable over time (discounting for the temporary increase due to chemical injections). Completeness: Completeness is a measure of the amount of valid data obtained from a measurement system compared to the amount expected under normal conditions. Twenty-two discrete soil samples were collected from the site. A total of 31 groundwater samples were collected from the site over an 11 year period. One soil gas sample and one groundwater sample were collected from the site on March 25, 2011. The disposal site boundary/limits of RAO are shown on the Figure 3 Site Plan in Appendix B and measure approximately 60 feet by 60 feet. It is our opinion that the soil sample density, spatial distribution of the soils samples submitted for laboratory analysis, spatial distribution of groundwater monitoring wells, the number of groundwater sampling events and the location and number of soil gas and indoor air sampling events was sufficient to characterize the release area. Comparability: Comparability expresses the confidence with which one data set can be compared to another. This project involved field screening of soil samples with a PID, laboratory analysis of soil samples for EPH and/or VPH, laboratory analysis of multiple groundwater samples for EPH and/or VPH, and laboratory analysis of soil gas and indoor air samples for APH. All soil and groundwater samples were analyzed by the MA DEP EPH and/or VPH method. Soil gas and indoor air samples were analyzed by the MA DEP APH method rev1. These analytical methods are the most current methodologies for these analyses and are appropriate for site characterization of the site contaminant (No.2 fuel oil). Sensitivity: Sensitivity is the ability of the method to detect contaminants of concern at the concentrations of interest. Reporting limits for all analyses were below their respective Cleanup Standards for samples analyzed as part of the remedial and monitoring activities performed at the site. Based on this evaluation, it is our opinion that the data is both useable and representative of site conditions and is appropriate to support an RAO. FSECTION 5 Tighe&Bond Response Action Outcome Statement RTN 1-13601 5-1 Section 5 Response Action Outcome and Public Notification 5.1 Response Action Outcome On behalf of 47 Center Street, LLC, Tighe & Bond has completed this Class A-2 RAO for RTN 1-13601 for a release of No. 2 fuel oil from a former UST located at 47 Center Street in Northampton, Massachusetts. Based on our assessment, delineation and remedial activities performed and our review of the data collected from the site, it is our opinion that the soil and groundwater contaminant concentrations have been adequately reduced and there are no complete exposure pathways that could result in potentially significant exposures. Therefore, a condition of No Significant Risk exists at the site and a Class A-2 RAO Statement is appropriate for this release. The disposal site boundaries and limits of the RAO are indicated on the Figure 3 Site Plan in Appendix A. A portion of the RAO boundary is within the public right-of-way fro Center Court, therefore the City of Northampton has been provided notice of this RAO. The original RAO Statement Transmittal Form (BWSC 104) was submitted via eDEP. 5.2 IRA and Phase IV Completion The objectives of IRA activities at the site have been completed, which have included periodic monitoring and gauging of LNAPL thickness, removal of LNAPL, and additional environmental media sampling (soil, groundwater, soil gas, indoor air). It is the opinion of Tighe & Bond that the response actions that are the subject of this submittal have been developed and implemented in accordance with the MCP and adequately addressed the IRA condition of LNAPL present at the site. No further immediate response actions are proposed at this point. Phase IV activities included chemical injections. No additional chemical injections are proposed and therefore Phase IV activities are complete. No specific final Phase IV inspection is necessary since no remedial system was constructed as part of the Phase IV activities. Based on this RAO filing, Phase V Operation, Maintenance, and/or Monitoring activities will not be required. The original IRA Transmittal Form (BWSC-105) and Phase IV Transmittal Form (BWSC- 108) was submitted via eDEP. 5.3 Public Notification In accordance with the public notification requirements of the MCP, 310 CMR 440.1403(3)(f) and (h), the City of Northampton has been notified of the submittal of this RAO Statement. Copies of all public notification documents are provided in Appendix D. Report limitations are provided in Appendix E.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 03/28/2011; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 6.0 C. Note: All samples which require thermal preservation are considered acceptable if the arrival temperature is within 2 C of the required temperature or method specified range. For samples with a specified temperature of 4 C, samples with a temperature ranging from just above freezing temperature of water to 6 C shall be acceptable. Samples that are hand delivered immediately following collection may not meet these criteria, however they will be deemed acceptable according to NELAC standards, if there is evidence that the chilling process has begun, such as arrival on ice, etc. TestAmerica’s Reporting Limits (RLs) for this report do not meet WSC-CAM-III method reporting limits due to various reasons such as methodology, dilutions or moisture content (soils). TestAmerica’s MA pivot table EDD documents which compound(s) exceed certain regulatory standards.

EXTRACTABLE PETROLEUM HYDROCARBONS Samples EW-1 (360-32914-1), MW-6 (360-32914-2), MW-7 (360-32914-3), MW-8D (360-32914-4), MW-10 (360-32914-5), MW-9D (360-32914-6) and MW-9D (FILTERED) (360-32914-7) were analyzed for extractable petroleum hydrocarbons in accordance with MA DEP MA-EPH. The samples were prepared on 04/06/2011 and analyzed on 04/07/2011. Benzo[g,h,i]perylene, n-Hexatriacontane and Indeno[1,2,3-cd]pyrene failed the criteria low for the closing CCV. The samples submitted for MA DEP EPH analysis were received with sufficient preservation (pH <2). According to EPH method reference 11.2.6.2, using GC/MS, the laboratory has identified a single component contaminant that appears at the same retention time in all laboratory and field samples. This contaminant is derived from the method's SPE cartridge and is not included in the calculation of the C11-C22 Aromatics range. No other difficulties were encountered during the EPH analyses. All other quality control parameters were within the acceptance limits.

The 47 Center Street site is the location of a historical release of No. 2 fuel oil from an underground storage tank (UST). The RAO Statement details assessment and remedial activities performed at the site in response to the historical fuel oil release. As a result of assessment and remedial activities performed at the site, a Class A-2 RAO Statement has been prepared for the release, indicating that a condition of No Significant Risk of harm to health, safety, public welfare and the environment exists at the site and no further response actions are required. A portion of the disposal site boundary is located with Center Court (City public right-of-way), therefore you are receiving a copy of this report also. A copy of the RAO submittal is also available for review online at DEP’s website. The file can be accessed at the following web address: http://public.dep.state.ma.us/wsc_viewer/main.aspx, under the file listed for DEP RTN 1-13601. In addition, public file review sessions are scheduled weekly by appointment. For more information about file reviews, please call the MADEP Service Center at (413) 784-1100.
