4 RAM Status Report F.B. Rogers Taunton, MA September 15, 2011 Page Introduction BETA Group, Inc. (BETA) has prepared this Release Abatement Measure (RAM) Status Report for the F.B. Rogers property located at 414 West Water Street, Taunton, Massachusetts (the Site) in accordance with the Massachusetts Contingency Plan (MCP) 310 CMR This RAM Status Report summarizes response actions taken to addresses metals and volatile organic compounds (VOCs) in soil and groundwater beneath the former Site building. Release Tracking Number (RTN) was assigned to the Site by the Massachusetts Department of Environmental Protection (MassDEP) in 2005 for the discovery of contaminated soil beneath the Site structure. A second RTN, , was assigned in February 2007 when a petroleum release was discovered during the removal of a 5,000-gallon fuel oil underground storage tank (UST). An Immediate Response Action (IRA) Completion Report was submitted by Gale Associates, Inc. of Weymouth Massachusetts on April 27, 2007 and RTN was linked to RTN This RAM Status Report outlines the response actions and requirements necessary to achieve a condition of No Significant Risk under MCP regulations and provides a status of current Site activities. 2.0 Site Background Information The Site is located on 2.29 acres of land and is the former location of the F.B. Rogers Silversmiths facility, a four-story mill structure that consisted of a series of connected buildings. The Site was used as a metal plating facility until The City of Taunton acquired the property in 2001 for the nonpayment of taxes. The property is bordered to the west by West Water Street and to the east by the Taunton River. The majority of the F.B. Rogers structure was demolished in May/June 2009, with plans to redevelop the remaining Building A into residential housing. The Site is located within a commercial and industrial area. No residences, schools or institutions are located within the immediate vicinity of the Site. A Site Locus is included as Figure Potential Sensitive Receptors The Taunton River lies immediately to the east of the Site. According to the MassDEP Priority Resource Map, there is an Estimated Habitat of Rare Wildlife in Wetland Areas associated with the Taunton River, as well as a protected open-space area located approximately 200 feet to the east of the Site. There is also a medium yield non-potential water source area located approximately 500 feet to the southwest. There are no private or public wells located within a half mile of the Site.

5 RAM Status Report F.B. Rogers Taunton, MA September 15, 2011 Page Person Assuming Responsibility for Release The potentially responsible party for this release is: City of Taunton Office of Economic and Community Development 45 School Street Taunton, MA Contact: Mr. Kevin Shea Executive Director Phone: (508) The City, as owner of the property, has assumed responsibility for conducting the Release Abatement Measures described in this report. 4.0 Description of Releases RTN During subsurface investigations, elevated concentrations of metals and VOCs were discovered under the central and southern section of the building. The source of this contamination is likely from historical Site usage. A Release Notification Form was submitted to the MassDEP on April 7, 2005, and RTN was subsequently assigned. RTN On February 27, 2007, the MassDEP was notified of a headspace reading greater than 100 parts per million (ppm) in a soil sample collected within ten feet of an UST excavation. An IRA, consisting of removing up to 200 cubic yards of soil and dewatering, was verbally approved. RTN was assigned, and a Notice of Responsibility (NOR) was issued to the City of Taunton. An IRA Plan/Completion Report was submitted in May 2007 and RTN was linked to the original RTN Previous Site Investigations and Remedial Actions 5.1. Soil Sampling A total of thirty-two (32) soil samples were collected from beneath the Site structure between December 1, 2004 and March 7, 2007 by previous consultants. Sampling depths ranged from zero (0) to twenty (20) feet below grade. Results indicated that concentrations of Trichloroethene, Arsenic, Cadmium, Chromium, Nickel, Lead, Silver and Zinc exceeded Method 1 S-1/GW-2 and S-1/GW-3 Standards. Soil sampling locations are shown on Figure 3 and results are summarized in Table 1. In February 2009 BETA was retained by the City to continue assessment activities at the Site. On March 6, 2009, representatives from BETA collected six (6) soil samples from the crawlspace of

6 RAM Status Report F.B. Rogers Taunton, MA September 15, 2011 Page 3 Buildings C, D, and G. Soil samples were collected from 0 to 6 inches below grade and analyzed for 8 RCRA Metals by New England Testing Laboratories, Inc. (NETLab) of Providence, Rhode Island. Results indicated levels of Cadmium, Chromium and Lead in the samples collected from Buildings C and D exceeded the applicable Method 1 Standards. Sampling results are summarized in Table 1. On April 23, 2009, soil samples from the crawl space of Building D were collected for asbestos analysis. Soil was sampled in a ten (10)-foot grid pattern. A total of forty-four (44) samples were collected and submitted for analysis. Asbestos was confirmed to be present in the soil over the entire sampling area. Asbestos-impacted soil was managed off-site by a licensed abatement contractor (Suburban Middlesex, Inc.) prior to building demolition, under the MassDEP s asbestos regulations. On May 29, 2009, three (3) soil samples (composites) were collected from Building D and submitted for SVOC and 8 RCRA Metals analysis. All results are below applicable Method 1 Standards. On July 1, 2009, soil samples were collected from six test pits (TP-1 through TP-6), located in a narrow area of pavement between the building and West Water Street, as shown on Figure 4. Samples were collected from the walls of the test pits, from zero (0) to three (3) feet in depth, and submitted for 8 RCRA Metals and semi-volatile organic compounds analysis. The results were compared to MassDEP background levels in soil containing fill material. All results were below background levels with the exception of Barium (TP-1 and TP-2). Although Barium concentrations exceed the background level of 50 mg/kg, they are below the S-1 Reportable Concentration of 1,000 mg/kg. Sampling results are summarized in Table Groundwater Sampling Depth to groundwater ranges from three (3) to eight (8) feet below surface grade. Groundwater flows toward the Taunton River and is tidally influenced. Site groundwater is classified as GW-2/GW-3 because a portion of the Site is located within 30 feet of an existing or planned building, and the average annual depth to groundwater is 15 feet or less. A total of thirty-five (35) groundwater samples were collected from sixteen (16) monitoring wells at the Site between December 4, 2004 and June 7, 2007 by previous consultants. Results indicated that Lead is present in Site groundwater at concentrations that exceed GW-3 Standards. Trichloroethene (TCE) and vinyl chloride have also been detected at several Site monitoring wells at concentrations that exceed GW-2 Standards. To date, samples collected from monitoring well GMW- 7H have exhibited the highest levels. Currently, no structures exist within 30 feet of any of these impacted wells. The locations of groundwater monitoring wells are shown on Figure 2. Groundwater sampling results are summarized in Table Building Demolition In February 2009, BETA was retained by the City s Office of Economic and Community Development to perform supplemental building and environmental investigations, and finalize the respective Contract Documents for demolition of the buildings on the subject Site. During the design phase, BETA provided a conceptual cap design for much of the disposal site, consistent with the

7 RAM Status Report F.B. Rogers Taunton, MA September 15, 2011 Page 4 redevelopment plan for the area prepared by Bargmann, Hendrie, & Archetype (BH&A). The redevelopment plan is in anticipation that an Activity & Use Limitation will be implemented to support a Response Action Outcome (RAO) for the Site. In May and June 2009, Costello Dismantling Company, Inc. demolished Buildings B, C, D, E F, G, H, J, K, L, and M of the facility. Once the demolition was completed the remaining footprint of Buildings D, E, F, and G were exposed to the subsurface. A partial (permeable) soil cap was constructed over the footprint as described in the following section. The footprint of Buildings B and C are to be paved and the concrete sub-slab remains exposed from Buildings H, J, L, K, and M. All remaining drains are to be removed and/or sealed in place Permeable Soil Cap BETA provided a permeable cap design for the disposal site, consistent with the redevelopment plan for the area prepared by BH&A. A partial soil cap is located over the exposed building footprint of Buildings D, E, F, and G. Figure 4 shows the location of the soil cap. The soil cap consists of a permeable geotextile fabric, which was placed over two (2) feet of run-of-bank gravel. Four (4) +/- inches of #2 stone was then placed over the gravel layer for stability and dust control. Another eight (8) to twelve (12) inches of loam will be eventually placed over the stone and seeded. Twelve (12) inches of rip-rap and/or other suitable surface protection is proposed to be placed over the soil cap along the side of the Taunton River. A drainage swale has been constructed on the West Water Street side of the cap to aid in the infiltration of storm-water runoff. Please note that that a permanent fence has been constructed around the entire Site to restrict access until the cap is completed. 6.0 Scheduled RAM Activities Location and cleaning of floor drains within the building footprint and storm drains from West Water Street to the Taunton River Supplemental sampling of soil and groundwater in the vicinity of historic detections of metals and VOCs Once this supplemental data is obtained, an evaluation of remedial options to address metal and VOC contaminated soil and groundwater will be made. The F.B. Rogers property was recently subdivided into two separate lots. In order to make the northern lot more desirable to potential purchasers, the previously constructed mounded partial cap will be removed and redesigned in order to match the surrounding elevation. This work is scheduled to be completed this fall. Figure 4 depicts the newly divided lots.

8 RAM Status Report F.B. Rogers Taunton, MA September 15, 2011 Page Remediation Waste As described in Section 5.1, asbestos-impacted soil was managed off-site by a licensed abatement contractor (Suburban Middlesex, Inc.) prior to the demolition of the buildings, under the MassDEP s asbestos regulations. No additional remediation waste has been generated since demolition was completed in Federal, State, or Local Permits Other than the approvals required by MassDEP, no other federal, state or local permits are likely to be needed to conduct this RAM. 9.0 Other Information Required by the Department BETA is not aware of any additional information required by the MassDEP LSP Opinion It is my opinion that RAM activities have been conducted in general conformance with 310 CMR and the applicable provisions of the July 22, 2009 RAM Plan Modification Schedule EPA Brownfields funding has recently been awarded to the City. RAM activities, as described above, are scheduled to be completed within the next month. The City intends to apply for the next upcoming EPA grant (October 2011) in order to secure additional funds to complete the next phase of cleanup.
