This Release Abatement Measure (RAM) Completion Report has been prepared to I describe remediation activities that have been completed at the former Hersey Products, Inc. property, DEP Release Tracking Number (RTN) 3-1196 in accordance with the i RAM Plan submitted to DEP on July 31, 2001. The RAM Plan was prepared for remediation of lead-containing soil on a portion of the site, located at 250 Elm Street in Dedham, Massachusetts. A Site Locus (Figure 1) and MassGIS Natural Resources 1 Plan (Figure 2) are included in Appendix A. The impacted soil that was remediated during this RAM extended to depths of 2 to 7 feet below ground surface (bgs) primarily on the eastern portion of the site, in the areas shown in Appendix A, Figure 3. The I RAM work was performed by Grinnell Corporation, which acquired the former site owner, Hersey Products, Inc. in 1986. The site property is currently owned by WXV 250 Elm LLC and is planned for redevelopment as a commercial office park. I The site property was initially developed in the 1950s by Hersey Products, Inc. as a foundry and manufacturing facility for the production of brass and iron valves. The 3facility operated until the mid 1980s, when the facility was closed and the property sold. WXV 250 Elm LLC acquired the property in September 2000 and has since demolished the former foundry and manufacturing buildings and prepared plans to develop the property as a commercial office park.

Preliminary characterization of the lead-containing soil detailed in the RAM Plan indicated I the impacted soil was located adjacent to the former foundry building, along the eastern portion of the property. Pre-characterization borings indicated that the soil generally I consisted of shallow fill, mostly located beneath pavement, in the area depicted in Figure 3. Laboratory analysis results indicated that total metals, including antimony, copper, lead and zinc, were present above their applicable Massachusetts Contingency Plan (MCP) I Method 1,S-1 soil standards of 10 mg/kg, 1,000 mg/kg, 300 mg/kg and 2,500 mg/kg, respectively. Although other metals have been detected in the impacted soil, lead was generally detected at the highest concentrations and at the highest level above its Method 1 I risk characterization standard in soil. Therefore, lead was used as the primary constituent for determining the extent of excavation. Several monitoring wells previously located in the vicinity of the RAM excavation area were sampled prior to implementation of the 3RAM for dissolved metals, of which none were detected above the applicable Method 1, GW-2/GW-3 standards. IRAM excavation began on October 15, 2001 and continued through October 24, 2001. A total of approximately 2,100 cubic yards of lead-impacted soil was excavated. Approximately 1,400 cubic yards of soil characterized as hazardous (based on TCLP lead I concentrations greater than 5 mg/L) has been removed from the site for off-site disposal. The remaining 700 cubic yards, characterized as non-hazardous, was removed from the I site for landfill reuse beginning November 26, 2001. The excavation was backfilled with clean fill between November 26 and December 3, 2001. Three groundwater monitoring

Release Abatement Measure Completion Report U I I ECTION 1 INTRODUCTlON Trighe&Bond wells were installed on December 4, 2001 and follow-up groundwater sampling was Sperformed on December 11, 2001. The objective of this RAM was to excavate soil with concentrations of total lead and other I associated metals (antimony, copper and zinc) from the 250 Elm Street property to achieve a condition of No Significant Risk of harm to human health, public welfare or the environment. Based upon confirmatory soil and groundwater sampling results, completion of the remedial activities specified in the RAM Plan has resulted in removal of the impacted soil from the 250 Elm Street property. However, based on soil sampling results from the eastern wall of the RAM excavation, residual elevated metals concentrations/ remain in soil at the property line with the easterly abutting property. Some of the residual soil at the property containing elevated metals concentrations is visually similar to the surficial black fine casting sands previously identified and remediated at the 250 Elm Street property. However, samples with residual metals I concentrations from the northeast portion of this RAM excavation were collected from historical fill with different visual characteristics from the black sand. Further, the samples collected from the historical fill at the property line generally correlate with the location of i previous assessment on the abutting property, for which a risk characterization and Response Action Outcome (RAO) was filed in 1998 (RTN: 3-016844, 367-419 Rustcraft/ Road). The abutting RAO area is shown in Figure 3 and a detailed discussion of the soil results for the RAM confirmatory samples are provided in Section 2.3.2 of this report. / This RAM Completion Report confirms completion of remediation of lead-containing soil I on the 250 Elm Street property, according to the RAM Plan. Additional assessment of surficial black casting sand encountered at the southeastern excavation wall is anticipated for the adjacent portion of the abutting property. No further assessment of historical fill encountered at the northeastern RAM excavation wall is planned, as this soil on the abutting property has previously been assessed and issued a RAO. 3 This RAM Completion Report was prepared in accordance with the MCP (310 CMR 40.0440), by Evan T. Johnson, P.E., LSP, of Tighe & Bond, Inc. on behalf of Grinnell Corporation. The DEP transmittal form (BWSC-106) for this RAM Completion Report is 3 included in Appendix B. I I

Release Abatement Measure Completion Report I I SECTION 2 RELEASE ABATEMENT MEASURE Tighe&Bond I 2.1 PRE-RAM ACTIVITIES Prior to beginning excavation at the site, a silt fence was installed along the eastern and northern perimeter of the property. The silt fence was installed in accordance with the I Special Conditions issued along with the negative Determination of Applicability by the Dedham Conservation Commission for the property redevelopment. Subsequent to silt I fence installation, construction of a new section of Town of Dedham sewer line, relocated as shown in Figure 3, was begun. A portion of the lead-impacted soil area proposed for excavation was located within a 10-foot wide Town of Dedham sewer easement along the I eastern border of the property. A 12-inch diameter sanitary sewer, with invert elevations located between approximately 1.5 feet and 3 feet below grade, traversed this easement. Soil analytical data from borings advanced in and adjacent to the sewer easement indicated that the lead-containing soil was located in the easement and, in some locations, beneath the sewer pipe. In order to facilitate removal of lead-containing soil surrounding the sewer line, a new, relocated sewer was installed. This sewer was put into operation prior Sto the excavation of lead-impacted soil and removal of a portion of the former sewer. In accordance with an agreement between the Town of Dedham, Grinnell and the current property owner, the sewer was relocated as shown on Figure 3, where a new easement will be established. Once the relocated sewer was operational on October 10, 2001, RAM soil excavation was scheduled and subsequently begun on October 15, 2001. 1 2.2 RAM ACTIVITIES I From October 15, 2001 through October 24, 2001, Franklin Environmental Services of Wrentham, Massachusetts was onsite to perform RAM activities under supervision of Tighe & Bond personnel. Soil excavation was performed with a track-mounted excavator. 1 Soil was transported to a paved temporary holding area on the site with a dump truck or front-end loader and placed in approximate 100 cubic yard stockpiles. Composite samples were then collected from each stockpile for analysis for final disposal characterization.

U Confirmatory soil samples were collected from the base and walls of the excavation as excavation progressed. Confirmatory soil samples (Conf-1 through Conf-46) were submitted to Severn Trent Laboratories (STL) in Westfield, Massachusetts for total metals analysis (antimony, copper, lead and zinc). The extent of excavation, confirmatory soil sample locations and pre-characterization boring locations are shown on Figure 3. 3 A total of approximately 2,100 cubic yards of lead-impacted soil was excavated. Backfilling of the excavation was completed on December 3, 2001. The excavation areas I were backfilled with virgin fill, obtained and transported to the site by A.A. Wills Materials Corporation of Carver, Massachusetts. Franklin placed and compacted the ibackfill in one-foot lifts using a bulldozer and vibratory roller. Subsequent to backfilling, three groundwater monitoring wells were installed in the excavation area and sampled as

Release Abatement Measure Completion Report I I

SECTION 2 RELEASE ABATEMENT MEASURE righe&Bond proposed in the RAM Plan. Specifically, on December 4, 2001, three monitoring wells I were installed at the site by B.L. Myers Bros. of Belchertown, Massachusetts under the supervision of Tighe & Bond personnel (RMW-10, RMW-11 and RMW-12). The locations of the monitoring wells are included on the Site Plan (Figure 4 in Appendix A).

I The monitoring wells were installed in the eastern portion of the backfilled excavation area. The wells were installed using a Mobile Drill B-61 rig equipped with 4.25-inch diameter hollow stem augers. During monitoring well installation, soil samples were collected in 5-foot intervals with a clean, 2-inch diameter split-spoon sampler. Detailed boring logs are provided in Appendix C. Monitoring wells were constructed of 2-inch 5 inside diameter flush-threaded Schedule 40 PVC well materials with 10-foot sections of 0.010-inch slotted screen. Groundwater was encountered at approximately 7 feet below grade at each location. The monitoring wells were installed to total depths of 15 to 17 feet I below grade to insure that the screened interval is at a depth that intersects water table as encountered while drilling. 3 The annular space surrounding the well screen was filled with No 1 filter sand and extends approximately two feet above the top of the screen to allow for settlement after i installation. A two-foot seal of bentonite chips was placed above the sand pack. Each well was then completed at the surface with a locking standpipe and finished with a concrete surface seal. S2.3 MONITORING DATA AND FINDINGS 3 2.3.1 Air Monitoring Data During RAM excavation and soil removal activities, ambient air monitoring was I performed to monitor for generation of dust potentially containing lead levels of concern. Respirable dust was measured with a Miniature Real-time Aerosol Monitor (MINIRAM) in and downwind of the lead soil excavation area for confirmation that 3 dust levels were maintained below the 1.3 mg/cubic meter threshold established in the RAM air monitoring program. This value was calculated to maintain lead levels in repirable dust below the OSHA 0.03 mg/cubic meter threshold. During excavation, instantaneous readings (read at 10 second intervals) measured by the MINIRAM range from 0.11 to 1.24 mg/cubic meter. In general, most readings were below i approximately 0.40 mg/cubic meter. To confirm MINIRAM readings, ambient air samples were collected using low-flow air pumps and dust sample collection filters on October 16 through October 18, 2001. Samples were collected downwind and upwind I of the excavation and submitted to International Asbestos Testing Laboratories (IATL) in Mt. Laurel, New Jersey for lead air analysis. Sample results for October 16 and 17, 2001 were below detection limits of 0.002 mg/cubic meter, and lead was detected at the I detection limit of 0.002 mg/cubic meter in the sample collected on October 18, 2001. Air monitoring results indicate that no lead levels of concern were generated as a result

of the RAM soil excavation activities. Copies of air sample laboratory analytical 3 reports are provided in Appendix D. 2.3.2 Soil Analyses Data and Findings

U During the soil excavation activities conducted between October 15 and October 24, 2001, confirmatory soil samples Conf-1 through Conf-46 were collected from the I sidewalls and bottom of the excavation area and submitted to STL for analysis of total lead, antimony, copper and zinc. Confirmatory sample analyses are summarized, along with pre-characterization data, in Tables 1, 2 and 3 in Appendix E. Copies of the 5 complete laboratory analytical reports for this RAM data are provided in Appendix D.

Confirmatory sample results along with visual field observation confirmed that shallow Ifill soil, generally ranging in color from brown to black, contained elevated metals concentrations. Horizontal lenses of this fill were excavated to the extent feasible in the areas shown in Figure 3, and were consistent with the impacted area delineated in the SRAM Plan. The excavation extended to the eastern property line, where confirmatory sample concentrations indicate generally higher metals concentrations associated with ishallow fill in several samples collected at the property line. The elevated metals concentrations in the property line soil samples are associated with two distinct types of fill:

3 1.Surficial fine black sand encountered along the southeastern portion of the excavation; and

3 2. Brown to dark brown historical fill and solid waste encountered along the northeastern portion of the RAM excavation.

3 The surficial black sand is visually similar to the black casting sand used in the former Hersey foundry operations. An area of these sands on the northeastern corner of the I property was previously remediated and closed with an Activity and Use Limitation (AUL). Along the vertical southeastern wall of the 2001 RAM excavation, similar surficial black sand was observed to range in thickness from several inches to I approximately 2.5 feet. Laboratory results for composite samples (Conf-6, -16, -23, - 36) collected from this soil are listed at the end of Table 1 in Appendix E. These composite soil samples represent surficial soil samples collected from east wall sample locations Conf-2, -5, -8, -12, -15, -19, -22 and -36 shown in Figure 3.

Elevated residual metals concentrations were also detected in a second fill horizon, Sconsisting of brown to dark brown historical fill along the northeastern portion of the RAM excavation. Specific components observed in this fill included ash, cinder, metal ifragments, glass, organic silt and roots. Laboratory analytical results characterizing this fill are listed in Table 2.This historical fill was generally encountered from 0 to 3 feet

bgs along the northeastern portion of the excavation. Sampling locations in this I historical fill correlate with the location of previous soil sampling, assessment and risk characterization work performed on an adjacent portion of the abutting property (identified as 367-419 Rustcraft Road, RTN: 3-016844). A report reviewed for RTN: S3-016844 indicates that metals (primarily lead, detected at concentrations up to 4,100 mg/kg) were detected in soil during previous investigations on that property, and a risk characterization was performed in support of a RAO for a portion of that property. The 3RAO area for RTN: 3-016844 abuts the 250 Elm Street property line and RAM excavation "wall" as shown in Figure 3.

5 Data for soil that has been excavated and removed from the 250 Elm Street property during this RAM is listed in Table 3.

2.3.3 Groundwater Analyses Data and Findings

IGroundwater samples were collected from each of the monitoring wells by Tighe & Bond personnel on December 11, 2001. Groundwater samples were collected using low-flow methodology and submitted to STL for priority pollutant 13 metals and i barium analysis. Copies of the complete laboratory reports are provided in Appendix D and groundwater sample analytical results are summarized in Table 4 provided in Appendix E, along with the applicable MCP Method 1, GW-2/GW-3 standards. Results I from previous groundwater samples collected from decommissioned wells at the site are also listed in Table 4. Concentrations of metals were not detected in samples collected from RMW-10, RMW-11 and RMW-12, except for barium. Dissolved barium was 3 detected at concentrations well below the applicable cleanup standards.

During sample collection, depth to water table measurements were performed with the purpose of preparing a groundwater flow contour plan. Water level measurements are summarized in Table 5 in Appendix E and the groundwater flow contour plan is provided as Figure 4 in Appendix A. As shown on the contour plan, the inferred Sdirection of groundwater flow is toward the north. I 2.4 MANAGEMENT OF REMEDIATION WASTE Upon excavation, soil was placed in approximate 100 cubic yard secured stockpiles on i pavement north of the former foundry building. Composite samples were collected from each stockpile and submitted to STL for total and TCLP lead analyses. Stockpiles characterized as hazardous (TCLP lead greater that 5 mg/L or total lead greater than i2,000 mg/kg) were designated for shipment to an approved off-site disposal facility. This soil was transported to Horizon Environment, Inc., Grand-Piles, Quebec, Canada under hazardous waste manifest between October 29 and November 8, 2001. Based on I the number of trucks loaded from each stockpile, approximately 1,400 cubic yards (2315 tons) was transported to Horizon Environment facility. A summary of the soil

Release Abatement Measure Completion Report I I 3 SECTioN 2RELEASE ABATEMENT MEAsuRE Tighe&Bond stockpile information and lead data is provided in Table 6 in Appendix E and I representative examples of the state and Canadian hazardous waste manifests are provided in Appendix F. Soil stockpiles characterized as non-hazardous and containing total lead and other constituent concentrations below landfill reuse criteria were transported to the BFI Fall River landfill. Between November 26 and November 29, 2001, approximately 700 I cubic yards (1212 tons) of non-hazardous soil was shipped under a Massachusetts DEP Bill-of-Lading (BOL) to the landfill. On November 28, 2001, the paved area where soil stockpile staging was performed was swept with a mechanical sweeper. The sweepings 3were appropriately disposed off-site along with the impacted soil. A copy of the complete BOL for management of the remediation waste is provided in Appendix G. U I I I I I I I I I

Release Abatement Measure Completion Report U I SECTION 3 SUMMARY AND CONCLUSIONS Tighe&Bond

This Release Abatement Measure (RAM) Completion Report has been prepared to describe remediation activities completed and present data for the subject portion of the former Hersey Products, Inc. property, DEP Release Tracking Number (RTN) 3-1196. The work was completed in accordance with the RAM Plan submitted to DEP on July 331,2001 for the remediation of lead-impacted soil on the eastern portion of the site, located at 250 Elm Street in Dedham, Massachusetts. The impacted soil that was remediated during this RAM extended to depths of 2 to 7 feet below ground surface S(bgs) primarily on the eastern portion of the site, in the areas shown in Appendix A, Figure 3. The RAM work was performed by Grinnell Corporation, which acquired the former site owner, Hersey Products, Inc. in 1986. The site property is currently owned by WXV 250 Elm LLC and is planned for redevelopment as a commercial office park. RAM activities completed between October 15 and December 31, 2001 in accordance with the RAM Plan included: * Excavation and disposal at Horizon Environment in Quebec, Canada of i approximately 1,400 cubic yards of hazardous characteristic soil (TCLP lead concentrations greater than 5 mg/L). i * Excavation and off-site landfill reuse of approximately 700 cubic yards of non- hazardous lead-impacted soil. I * Confirmatory soil sampling from the base and walls of the excavation for the metals of concern (lead, antimony, copper and zinc). i * Backfilling of the RAM excavation with uncontaminated compacted fill. * Installation and confirmatory groundwater sampling of three monitoring wells in the RAM excavation area. I Laboratory results, field observations and historical information collected during the RAM activities indicate the following findings: S* Confirmatory sample results along with visual field observation confirmed that generally darker colored shallow fill soil contained elevated metals I concentrations. Horizontal lenses of this fill were excavated in the areas shown in Figure 3, and were consistent with the impacted area delineated in the RAM Plan. I* Confirmatory soil samples indicate significant reduction of metals soil concentrations on the 250 Elm Street property (see Table 1, Appendix E) and 3 completion of the RAM excavation, to the extent feasible, on the property. * Groundwater sampling results indicate that none of the four metals of concern iwere detected in groundwater (see Table 4, Appendix E), confirming that metals in soil had no significant impacts on the underlying groundwater.

5 SECTION 3 SUMMARY AND CONCLUSIONS righe&Bond SConfirmatory soil samples collected from the eastern wall of the excavation i(contiguous with the eastern property line of the 250 Elm Street property) identified elevated residual metals concentrations in soil samples associated with two distinct types of soil: 5 1)Surficial fine black sand encountered along the southeastern portion of the excavation; and 3 2) Brown to dark brown historical fill encountered from depths of 0 to 3 feet below grade along the northeastern portion of the RAM excavation. I * Historical research for the abutting property (identified as 367-419 Rustcraft Road, RTN: 3-016844) indicates that metals (primarily lead), were detected in soil during a previous investigation on the abutting property. A RAO, supported I by a risk characterization was filed for RTN: 3-016844 in 1998. The abutting RAO area is shown in Figure 3. I Conclusions regarding the RAM for the metals-impacted soil for the subject site, RTN: 3-1196 are as follows: I * Black fine sand and historical fill on the 250 Elm Street side of the property line were removed during the subject RAM activities, completing the work proposed in the RAM Plan. * Surficial property line soil samples with elevated residual metals concentrations from the southeastern portion of the RAM excavation consist of black sand similar I to characteristically black fine casting sand associated with former Hersey operations. Additional assessment of the surficial black sand on the adjacent portion of the abutting property is anticipated and a new RAM Plan will be 3 prepared should additional remediation be necessary. * RAM confirmatory samples with residual metals concentrations from the northeast iportion of the RAM excavation were collected from historical fill with different visual characteristics from the black sand. Samples collected from the historical fill at the property line correlate with the location of a previous assessment on the Iabutting property, for which a risk characterization and RAO was filed in 1998. No further assessment of historical fill encountered at the northeastern RAM excavation wall is planned, as this soil on the abutting property has previously g been assessed via a RAO and supporting risk characterization. This RAM Completion Report was prepared in accordance with the MCP (310 CMR 40.0440), by Evan T. Johnson, P.E., LSP, of Tighe & Bond, Inc. on behalf of Grinnell Corporation. The DEP transmittal form (BWSC-106) for this RAM Completion Report is included in Appendix B.

STL WESTFIELD/BILLERICA I DATA REPORTING QUALIFIERS AND TERMINOLOGY I A number of data qualifiers are widely used within the environmental testing industry and may be utilized in our data reports. The following definitions of these qualifiers are included as a service to our clientele. The majority of the qualifiers have evolved from the EPA contract laboratory program (CLP). I

ORGANIC QUALIFIERS

U - Indicates that the compound was analyzed for but not detected. The sample detection limit is corrected for dilution and percent moisture. This detection limit is not necessarily the instrument detection limit.

J - Indicates an estimated value. This qualifier is used when mass spectral data indicates the presence of a compound that meets the identification criteria and the result is less than the specified quantitation limit but no less than one-half the quantitation limit. Common laboratory contaminants are not reported below the quantitation limit.

B - Indicates that the analyte was found in both the sample and its associated I laboratory blank. It indicates possible/probable blank contamination and warns the data user to use caution when applying the results of this analyte. Common laboratory contaminants in applicable method blanks are reported with J qualifiers to one-tenth the quantitation limit.

E - This qualifier indicates compounds whose concentrations exceed the calibration range of the instrument for the specific analysis.

D - Indicates all compounds identified in an analysis at a secondary dilution factor.

RE - This suffix indicates a re-analyzed sample and is appended to the sample number on the result form.

RR - This suffix indicates a re-extracted and re-analyzed sample and is appended to the sample number on the result form.

INORGANICS

U - Indicates that the analyte was analyzed for but not detected. I

E - Indicates an estimated value because of the presence of interference.

Site History

The site is a former valve casting facility (approx. 1950's to 1987) that is located at 250 Elm Street, Dedham, Massachusetts. Currently, the site building has been demolished with only paved and unpaved flat areas remaining. Past operations included casting and manufacturing of brass and iron water valves and meters. Casting sand appears to have been mixed with fill on portions of the site property, resulting in elevated lead concentrations in some areas. The lead-containing soil was excavated from October 15 through October 29, 2001 and placed in approximately 100 cubic yard stockpiles for reuse/disposal characterization.

Composite samples were collected from the stockpiles for initial total and TCLP lead characterization (results attached in table of Landfill Reuse Stockpile Data). Two additional composite samples for landfill reuse parameter analysis were collected from the seven stockpiles identified as non-hazardous with respect to TCLP lead. One composite was collected from stockpiles 1, 2 and 8. The second composite was collected from stockpiles 19, 20, 21 and 22.

The composite samples were submitted to Severn Trent Laboratories for landfill reuse parameter analysis. The analytical parameters selected were 1) volatile organic compounds (VOCs), 2) semi-volatile organic compounds (SVOCs), 3) polychlorinated biphenyls (PCBs), 4) total petroleum hydrocarbons (TPH), 5) conductivity, 6) total metals (arsenic, cadmium, chromium, lead and mercury) and 7) toxicity characteristic leaching procedure (TCLP) lead. The laboratory analytical reports are attached. The results indicate that the soil in stockpiles 1, 2, 8, 19, 20, 21 and 22 meet the criteria for landfill reuse. LANDFILL REUSE STOCKPILE DATA

The following definitions of these qualifiers are included as a service to our clientele. The majority of the qualifiers have evolved from the EPA contract laboratory program (CLP).

ORGANIC QUALIFIERS

E - This qualifier indicates compounds whose concentrations exceed the calibration range of the instrument for the specific analysis.

D - Indicates all compounds identified in an analysis at a secondary dilution factor.

RE - This suffix indicates a re-analyzed sample and is appended to the sample number on the result form.

RR - This suffix indicates a re-extracted and re-analyzed sample and is appended to the sample number on the result form.

In addition to our standard data reporting qualifiers the following comments are specific to Total Petroleum Hydrocarbons, (Diesel or Gasoline Range Organics) by GC/FID.

PETROLEUM HYDROCARBON QUALIFIERS

Results for Motor Oil are based on chromatographable portions of the petroleum product.

The Carbon Range refers to the approximate chromatographic region covered by the specified petroleum product in straight-chain carbon units.

Quantitation is based on the average response factors for a series of hydrocarbon standards. The sample result from the DRO fraction is independent of the target compound assignment.

Samples yielding chromatographic patterns that do not agree with any of the method targets are reported as "unmatched."
