4 LIGHTSHIP ENGINEERING ASSESSMENT AND REMEDIATION CIVIL ENGINEERING ENERGY MANAGEMENT WATER AND WASTEWATER MANAGEMENT PERMITTING 1.0 INTRODUCTION On behalf of the Town of Grafton, (the Town ), Lightship Engineering, LLC ( Lightship Engineering ) has prepared this Release Abatement Measure Status Report ( RAM Status ) in connection with conducting a technology demonstration of the Global Biosciences, Inc. s ( GBI ) Butane Biostimulation Technology ( BBT ). The technology demonstration is being conducted in an area (the Demonstration Area ) impacted by a historic release of No. 4 and No. 6 fuel oil at the former Fisherville Mill property located at 60 Main Street in South Grafton, Massachusetts (the Site ). A Site Locus Map and Site Map are provided as Figures 1-1 and 1-2, Appendix A. This RAM Status was prepared pursuant to the Massachusetts Contingency Plan ( MCP, 310 CMR ). A Release Abatement Measure Transmittal Form (BWSC-106) and RAM Remedial Monitoring Reports (BWSC-106A) are being submitted to DEP concurrently with this RAM Status. 1.1 BACKGROUND The Site consists of an approximate 30 acre parcel of land located adjacent to the Blackstone River in Grafton, Massachusetts. The Site is bisected by Main Street (Route 122A) and was formerly occupied by the Fisherville Mill complex ( mill complex ). The mill complex operated between 1832 and 1986, when the property was abandoned. A variety of products were manufactured on the property including cotton goods, fabrics, aluminum goods, metal parts, and foam rubber. No. 4 and No. 6 fuel oil was previously stored in underground storage tanks ( USTs ) located along the banks of the Blackstone Canal (the canal ), in the area indicated on Figure 1-2, Appendix A. The USTs were removed in 1987 and an unspecified volume of petroleum related compound ( PRC ) impacted soils were excavated and removed from the Site. PRC impacted soils remain at the Site and non-aqueous phase liquid ( NAPL ) is present in the Demonstration Area and is periodically observed on surface water in the canal located east of and adjacent to the Demonstration Area. The Commonwealth of Massachusetts Department of Environmental Protection ( MassDEP ) assigned Release Tracking Number ( RTN ) to the release. Historical NAPL recovery activities within the canal included the use of petroleum absorbent booms, pumps and belt skimmers. NAPL recovery has historically been conducted using belt skimmers in the canal and two recovery wells on the landward portion of the PRC impacted. A NAPL collection system is currently present at the Site within a concrete Industrial Park Road Unit C Plymouth, Massachusetts (508) (508)

No soil samples were collected during the advancement of soil borings LE-AS1 through LE-AS7. Soil borings LE-AS1 through LE-AS7 were completed as biosparge wells LE-AS1 through LE-AS7, respectively at the approximate locations indicated on Figure 2-1, Appendix A. Consistent with the RAM Plan, biosparge wells were constructed of 1-inch diameter black iron piping with two feet of inch stainless steel screen. Biosparge wells LE-AS1 through LE- AS3, LE-AS5, and LE-AS7 were set with the stainless steel screen at 30 feet below grade, below the NAPL impacted soil zone. Biosparge wells LE-AS4 and LE-AS7 were set with the stainless steel screen at 25 feet below grade, within the NAPL impacted soil zone. Biosparge well construction logs are provided at Appendix B, and a typical biosparge well detail is provided on Figure 2-2, Appendix A. The biosparge wells were developed utilizing a peristaltic pump and electric air compressor. The wells were developed until groundwater flowed with a visually consistent clarity for a minimum of 15 minutes or for a maximum of one hour. Development water was discharged to the ground surface, pursuant to 310 CMR (7). After completion of groundwater purging, an electric air compressor was utilized to develop the biosparge wells. Air was injected into the biosparge wells until flow from the well was established. 2.3 ABOVEGROUND BIOSPARGE TRANSPORT PIPING AND BUTANE INJECTION PANEL INSTALLATION From December 5 through December 20, 2011, consistent with the RAM Plan, Lightship Engineering installed the above grade transport piping from biosparge wells LE-AS1 through LE-AS-7 to the butane injection panel and the biosparge air compressor, as indicated on Figure 2-1, Appendix A.
