Phase II Scope of Work 1-1

Section 1 Introduction Tighe & Bond has prepared a Phase II Scope of Work (SOW) on behalf of First Lawrence Financial, LLC for the Former Tombarello Property located at 207 Marston Street in Lawrence, Massachusetts. The Massachusetts Department of Environmental Protection assigned Release Tracking Number (RTN) 3-18126 to the release in March 1999. The site contains elevated levels of PCBs and heavy metals in surficial site soils and elevated levels of metals and VOCs in site groundwater. A Site Locus Map (Figure 1), a Massachusetts Geographic Information System (MassGIS) Priority Resource Map (Figure 2) and Site Plan (Figure 3) are included in Appendix A.

1.1 Site Description

1.1.1 Property Description and Use The property consists of a 14-acre parcel of land historically occupied by a City burn dump/landfill, and metal scrap recycling yard. The southern portion of the property was historically utilized as a soap manufacturing facility and a community landfill. The property contains several buildings and building foundation pads. The surface characteristics of the property consists of sparse vegetation and numerous soil piles.

1.1.2 Surrounding Properties The properties abutting or adjacent to the site include the following:

East: Route 495

South: Waste Management Facility. It should be noted that the Waste Management parcel was historically once part of the subject site during which time the collective parcels operated as a scrap recycling yard.

West: Marston Street and Parthum Elementary and Middle School

North: residential properties

1.2 Surrounding Resource Areas As shown on the MassGIS Map (Figure 2), portions of the subject property are located within the boundaries of a Non-Potential Medium Yield Drinking Water Source Area. No additional resource areas are located within the limits of the subject property. Additional resource areas located within one-half mile of the site include:

An unnamed tributary of the Merrimack River is located off-site to the south of the property.

The Merrimack River is located approximately 400 feet east of the site.

Areas identified by the Natural Heritage & Endangered Species Program as Priority Habitats Rare Species and Estimated Habitats for Rare Wildlife are both located approximately 400 feet east of the site.

Protected and Recreational Open Space is located approximately 400 feet southwest of the site.

Section 1 Introduction Tighe&Bond


A Potentially Productive Medium Yield Aquifer is located approximately 450 feet east of the site.

MassDEP identified Inland Wetlands are located approximately 900 feet north of the site.

A Solid Waste Landfill is located approximately 2,000 feet southeast of the site.

There are no additional mapped resource areas within one-half mile of the site. Resource areas are depicted on the Priority Resource Map (MassGIS map) which is included as Figure 2 in Appendix A.

1.3 Previous Assessment Activities The following is a summary of previous environmental assessment activities that have occurred at the site based on available reports provided to Tighe & Bond. The information was obtained through review of available environmental reports submitted to the MassDEP and EPA.

August 1998 – Environmental Site Assessment was conducted at the site by W.Z Baumgartner and Associates, Inc. (WZB) following closure of the metals recycling facility. Results of the assessment indicated concentrations of oil and hazardous materials exceeding Reportable Conditions (RCs). The assessment included collection of 15 soil samples between 0 to 11 feet below grade from nine boring locations. Analytical results for the samples indicated exceedences above RCs for SVOCs, TPH (diesel range), PCBs and metals. Additional assessment activities included installation of five groundwater monitoring wells and collection of groundwater samples for VOC, pesticides, metals, SVOCs, VPH, EPH and PCB analysis. Samples results indicated exceedences above RCs for arsenic, chromium and lead. Consequently, Release Tracking Number (RTN) 3-18126 was assigned by the MassDEP to the site for elevated contaminant concentrations.

April/June 1999 – An IRA Plan was submitted to MassDEP for the site to address the removal of a soil stockpile contaminated with heat transfer oil (RTN: 3-16817), collection and analysis of surficial soil samples and sampling and analysis of existing groundwater monitoring wells. A barbed-wired fence was also erected at the site to help control site access. The assessment included collection of 69 soil samples from depths of 0 to 6 inches. Analytical results for the samples indicated exceedences for extractable petroleum hydrocarbons (EPH), metals (lead), volatile organic compounds (VOCs) and PCBs.

June 1999 – MassDEP assigned RTN: 3-18431 for oily sludge that was observed on the baler/press room floor of the facility. American Recycling of Massachusetts, Inc. contested that the sludge originated from a sewer line and the RTN was retracted pending further evaluation of the sewer as a potential migration pathway. As part of additional assessment activities three additional groundwater monitoring wells were installed at the site in June 1999. The three wells, and one existing well were sampled and submitted for laboratory analysis of VOCs, metals, VPH and EPH. Analytical results indicated RC exceedences for VOCs and metals.

April 2000 – The site was classified as a Tier 1C site and RTNs: 3-18431 and 3-18126 were linked.



September 2001 – Haley & Aldrich, Inc. (H&A) collected 35 soils samples at depths ranging from 0 to 15 feet below surface grade. Twelve of the samples were collected from a soil berm located within the property limits and three samples were collected in the vicinity of the baler press building. Analytical results indicated exceedences of PCBs within various site areas.

September 2002 – H&A collected nine sediment samples from the Merrimack River for PCB analysis. Three of the samples reported elevated PCB concentrations, although additional upstream sampling in the river also identified elevated PCBs (see below).

February - September 2003 – Weston Solutions, Inc. (Weston) conducted a Phase II Comprehensive Site Assessment (CSA) which included surface soil, subsurface soil, groundwater and sediment sampling and analysis to further delineate the extent of contamination at the site. During assessment activities, Weston initially collected 28 soil samples between 0 and 7 feet below grade in February 2003. Analytical results indicated exceedences of EPH, metals and PCBs. Groundwater samples were also collected from seven existing monitoring wells during assessment activities. The samples were analyzed for VOCs and metals. Analytical results indicated concentrations of vinyl chloride in one downgradient monitoring well (MW-7) above RCs. Three sediment samples were also collected from the Merrimack River (two upstream and one downstream) and submitted for PCB analysis. PCB exceedences were reported for both upstream and downstream sampling locations. Weston returned to the site in July 2003 to collect 44 composite samples for PCB analysis. A total of 33 discrete samples were also collected from two previously identified “hot spot” locations. Results of the July 2003 assessment indicated elevated PCB concentrations. Additional soil sampling was conducted in September 2003 with the collection of 44 additional samples. Analytical results indicated elevated levels of PCBs.

A Risk Assessment was prepared for the site as part of the Phase II CSA. The risk assessment concluded the compounds of concern (COCs) in soil did not pose a significant risk to trespassers with the exception of one “hot spot” location (WSB-6). Risk to construction workers was identified within “hot spots” in the vicinity of WSB-6, CD-45, WSB-2, and deeper soils in the berms located on the east and southeast portions of the property. Risk to utility workers were identified in association with “hot spots” within the vicinity of WSB-6 and CD-45. The Risk Assessment indicated that PCB concentrations must be reduced to below 30 mg/kg and cadmium be reduced to below 350 mg/kg in all hot spot locations in order to achieve no significant risk (NSR) at the site. NSR assumed recording of a deed restriction.

October 2010 – EPA established a 50 foot by 50 foot grid throughout the property boundaries. Samples were collected from accessible grid locations and analyzed for PCB, metals and PAHs. A total of 161 samples were collected and submitted for laboratory analysis during the sampling effort.

EPA developed a removal action plan for the site to be implemented in Spring 2011 to remove limited quantities of contaminated soil from the Tombarello property and abutting residential properties to the north. The plan includes removal of abutting contaminated soils from the Tombarello property and removal of soils up to three feet deep from select abutting residential properties.



For reference, Tables 1 through 4 in Appendix B summarize analytical data available from historical assessment activities conducted at the property. Sample locations are depicted on Figure 4 in Appendix A. Information regarding the locations of historic borings S-8, S-9, F4, H6, I3 and WSB-9 could not be located on available historical site plans and are therefore not shown on Figure 4.

1.4 Underground Storage Tank History According to a Phase I ESA prepared for the site by W.Z Baumgartner & Associates in August 1998, there were no reported USTs existing on the property. According to the report, a UST containing gasoline was removed from the property in the mid-1980s and a diesel fuel tank was removed in 1996. A Report on Environmental Health and Safety Compliance Audit prepared by Haley & Aldrich in May 2001 indicated that an abandoned 275-gallon UST was located outside and adjacent to the Baler Press Building. The tank was reported to have been filled with a solid material.

Additional information regarding historic USTs at the site was researched using MassDEP’s online UST query software which identifies known UST to exist on properties throughout the state. According to information available on the website, four USTs have been removed from the site from 1976 through 1979. USTs removed included a 1,000-gallon and 4,000-gallon gasoline UST, and a 4,000-gallon and 10,000-gallon diesel fuel UST.

No other USTs are known to exist on site based on the available information that Tighe & Bond has reviewed.

1.5 Recent Site Activities

1.5.1 EPA Involvement EPA developed a removal action plan for the site to be implemented in Spring 2011 to remove limited quantities of contaminated soil from the Tombarello property and abutting residential properties. The plan included removal of soil from areas identified as “hot spots” on the Tombarello property and removal of soils up to three feet deep from select abutting residential properties.

The EPA indicated that FLF could elect to conduct certain remedial actions proposed to substantially minimize or eliminate the environmental lien that has been placed on the property and to help secure the site from a potential short-term risk standpoint.

Between the month of April and May 2011, Charter Environmental, Inc of Boston, Massachusetts completed the following site activities, on behalf of FLF under an EPA-approved Administrative Order of Consent (AOC):

1.5.2 Soil Excavation Activities Northern Property Boundary

On May 2 and 3, 2011, Charter completed excavation of an approximate 600’ x 50’ area (to a depth of 1 foot) of soil adjacent to fencing abutting the Hoffman Avenue residential properties located on the northern portion of the 207 Marston Street property. These excavated soils were relocated to the southern portion of the site in a predefined area measuring approximately 150’ long by 150’ wide. The soil consolidation area was



stabilized at the completion of excavation activities using filter fabric, loam, and seed as described in Section 1.4.5. Tighe & Bond personnel collected soil samples from the base of the excavation area prior to backfilling operations. A total of 15 samples (identified as PX-1 through PX-15) were collected from the excavation. Each sample was a composite of a 40’ long by 50’ wide area of the excavation. The samples were submitted to Alpha Analytical of Westborough, Massachusetts for PCB and RCRA-8 metals analysis. Post-excavation analytical results reported PCB concentrations ranging from 0.23 mg/kg to 14.8 mg/kg. Table 5 in Appendix B summarizes the post-excavation analytical results. The excavation was backfilled, loamed and seeded. A separation barrier of filter fabric demarcates the limits of the loam clean fill placed within the excavation.

Soil Consolidation Area

On May 2, 2011, Charter completed excavation of an approximate 35’ long by 15’ wide area of soil exhibiting oil staining from an excavator formerly stored on the property. The staining was located within the limits of the proposed soil consolidation area. Following excavation, the soil was placed on an existing concrete foundation pad located on the northeast portion of the property and covered with polyethylene sheeting. Management of this stockpile would occur as necessary during future response actions at the site.

1.5.3 Concrete Slab Removal Preparation of the soil consolidation area included the removal of a 20’ x 65’ x 1’ concrete slab. The slab was stockpiled on the central portion of the site.

1.5.4 Hazardous Waste Container Classification/Removal Miscellaneous hazardous waste containers and oily solids surrounding and beneath the containers were classified and removed from the property under Uniform Hazardous Waste Manifest documentation.

1.5.5 Loam and Hydro-seeding On-site excavation areas were backfilled with common burrow, followed by loam and hydro-seed. Upon completion of adding soils to the soil consolidation area, the area was covered with a non-biodegradable filter fabric, followed by loam and hydro-seed. Additional exposed areas of the property were also hydro-seeded.

1.5.6 Replace/Repair of Fencing Damaged fencing located along the perimeter of the property was repaired or replaced.

1.5.7 Signage Placement Signs were placed every 100 feet along the property boundary indicating that the site is contaminated.

Section 2 Phase II Scope of Work

2.1 Scope and Nature of Phase II Activities Phase II investigation activities will focus on further evaluating the extent of PCBs and/or metals contamination at the property. Proposed activities will include the collection of soil samples from specific areas of the site where the horizontal and vertical extent of contamination is not adequately defined. Additional Phase II activities will include the installation and sampling of groundwater monitoring wells and collection of sediment samples from on-site drainage structures. Further details of proposed activities are outlined in subsequent sections of this report.

2.2 Health & Safety Plan Development Tighe & Bond will prepare a site specific Health & Safety Plan prior to initiation of Phase II investigation activities.

2.3 Soil Borings Soil boring advancement will be conducted using a Geoprobe direct-push drilling unit. Soil samples will be collected every four feet and field screened for volatile compounds using a photoionization detector (PID). Select shallow sampling locations will be collected using a hand auger. A total of 82 soil borings are proposed throughout the property as part of Phase II investigation activities. Proposed boring locations include the following:

Areas that have historically reported PCB concentrations above 50 ppm to further delineate the horizontal and vertical extent of contamination. Soil samples will be collected from depths ranging from 0 (surficial) to 4 feet below surface grade (BSG). Soil samples will be submitted for laboratory analysis of PCBs. Select samples will also be submitted for RCRA-8 metals and/or hexavalent chromium analysis.

Paved areas located on the northwest portion of the property to delineate the horizontal extent of contamination. Soil samples will be collected from depths ranging from 1 to 3 feet BSG. Soil samples will be submitted for laboratory analysis of PCBs. Select samples will also be submitted for RCRA-8 metals and/or PAHs.

Vegetated areas located on the southeastern portion of the property to delineate the horizontal and vertical extent of PCBs and metals contamination. Soil samples will be collected from depths ranging from 0 to 4 feet BSG. Select samples will be submitted for laboratory analysis of PCBs and RCRA-8 metals.

The former metals shop building to assess for possible impacts beneath the foundation of the building. Soil samples will be collected from depths ranging from 1 to 3 feet. Soil samples will be submitted for laboratory analysis of PCBs and RCRA-8 metals. Select samples will also be submitted for PAHs.

Section 2 Phase II Conceptual Scope of Work Tighe&Bond


The former furnace building to assess for possible impacts beneath the building foundation as well as adjacent to the building in the vicinity of a former UST. Soil samples will be collected from varying depths which will be dependent on field observation and PID screening results. Soil samples will be submitted for laboratory analysis of PCBs, RCRA-8 metals, cyanide, VOCs and EPH. Select samples will also be submitted for hexavalent chromium.

The former baler/press area to assess possible impacts beneath and adjacent to the former concrete slab associated with the structure. Soil samples will be collected from depths ranging from 0 to 3 feet BSG. Samples will be submitted for laboratory analysis of PCBs, EPH and RCRA-8 metals. Select samples will also be submitted for PAHs.

The area of the former small sheer to assess possible impacts beneath the concrete slab associated with the former structure. Soil samples will be collected from depths ranging from 0 to 3 feet BSG. Soil samples will be submitted for EPH, VOC and PCB analysis.

The area of the former large sheer to assess possible impacts beneath the concrete slab of the former structure. Soil samples will be collected from depths ranging from 0 to 3 feet BSG. Samples will be submitted for laboratory analysis of EPH, VOC and PCB analysis. Select samples will also be submitted for PAHs.

The proposed soil boring locations are depicted on Figure 4 in Appendix A. Table 1 in Appendix C outlines the rationale for proposed soil boring locations and associated laboratory analysis.

2.4 Test Pit Excavations The Phase II investigation activities include the excavation of shallow test pits within existing soil berms and soil stockpiles. Test pits will be excavated using a rubber-tire backhoe. Each test pit will be restored to the extent feasible by backfilling the soils removed. Proposed test pit locations include the following: Berms A total of 12 test pits are proposed to assess for the presence of metals and PCB contamination in berms surrounding the southern and eastern perimeter of the site. Samples will be collected from depths ranging from surficial to 15 feet within the berms. Soil Stockpiles A total of 12 test pits are proposed to assess for the presence of metals and PCB contamination within soil stockpiles existing throughout the property. Soil samples will be collected from varying depths within the stockpiles. During test pitting activities, a real-time dust monitor will be utilized by field personnel to monitor dust conditions during those activities. If any visible dusts are generated during excavation or elevated of dusts above background conditions are detected, excavation work will stop and additional engineering controls will be evaluated.



The proposed test pit locations are depicted on Figure 4 in Appendix A. Table 1 in Appendix C outlines the rational for proposed test pit locations and associated laboratory analysis.

2.5 Monitoring Well Installations Select soil boring locations will be completed as groundwater monitoring wells. The wells will be installed using one-inch PVC Schedule 40 materials, with 10-foot section 0.010-slotted screen set across the water table, to the extent feasible, as encountered during drilling. Each well will be completed with a flush-mount road box concreted in-place, and will be developed for a short duration after installation. Eight monitoring wells will be installed as part of the proposed Phase II investigation activities. Proposed well locations include the following:

Paved area located on northwest portion of property (1 well) Within the former metal shop building (1 well) Within and adjacent to the former furnace building (2 wells) Former baler/press area (1 well) Former small shear area (1 well) Former large shear area (1 well) Southern area of site (1 well)

The proposed monitoring well locations are depicted on Figure 4 in Appendix A. Table 1 in Appendix C outlines the rational for each proposed well location.

2.6 Groundwater Sampling Approximately one week after well installation, Tighe & Bond will sample each of the new monitoring wells. The vertical elevation of each well will also be surveyed in order to establish groundwater flow direction. Groundwater samples will be collected using standard low-flow sampling techniques in general conformance with established EPA guidelines for low-stress groundwater sampling.

The groundwater samples will be submitted for laboratory analysis of EPH, PCB, physiologically available cyanide (PAC), VOCs, total cyanide and/or RCRA-8 Metals. The proposed monitoring well locations are depicted on Figure 4 in Appendix A. Table 1 in Appendix C outlines the rational for each proposed well location and associated laboratory analysis.

2.7 Drain Structure Sediment Sampling A visual survey of existing sewer and/or drainage structures will be conducted as part of Phase II investigation activities. Manhole and catch basin covers will be identified to the extent feasible and removed to visually observe and collect samples from sediments contained within the structures. It is anticipated that up to 4 sediment samples will be collected and submitted for laboratory analysis of PCBs and RCRA-8 metals.

2.8 Merrimack River Sediment Sampling Additional sampling of Merrimack River sediment is not proposed as part of this scope of work. However, Tighe & Bond will compare available chemical concentration data from the previous samples collected near the outfall pipe from the site within the Merrimack



River to chemical concentration data for upstream areas in the Merrimack River that represent local conditions. We will also research potential upstream sources of chemicals to the Merrimack River (e.g., other hazardous waste sites). The Phase II report will include a Stage I Environmental screening.

2.9 On-Site Utilities The site has a historic network of subsurface storm drainage piping/structures and an active sewer easement that serviced the site and other off-site locations. Approximate locations of mapped utility locations are shown on Figure 4. Some of the buildings may have been historically connected to the storm drainage network and/or sewer. Due to past building demolition and site disturbances that has occurred, this current scope of work does not currently include evaluating potential discharge locations of previous lateral service connections to for stormwater, sewer, and/or floor drains. However, during future site remediation and redevelopment, it will be necessary to cap former service connections that may have once existed. To accomplish this, a camera survey of the sewer line and drainage network would be performed. As lateral service connections are identified on infrastructure designated to remain, these connection points will be cut and capped. In addition, it is likely that the majority of the past drainage network will be removed and replaced to accommodate a new redevelopment layout.

2.10 Phase II Site Investigation Report Tighe & Bond will prepare a Phase II Assessment Summary Report at the completion of investigation activities. A Method 1 Risk Characterization for human health characterization (prepared by Tighe & Bond) and a Method 3 Ecological Risk Assessment (subcontracted to and prepared by Exponent of Maynard, Massachusetts) will also be included with the Phase II Summary Report.
