4 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Executive Summary GEI Consultants, Inc. conducted a Phase I Environmental Site Assessment (ESA) on behalf of the Washington County Council of Governments (WCCOG), for Schoppee s Garage on U.S. Route 1, on the northern side of the Chandler River, in Jonesboro, Maine (Site). The work was completed in support of a Site remediation plan proposed by the prospective Site owner, the Town of Jonesboro. This report incorporated information from a prior Phase I ESA prepared by GEI, dated February 3, 211. The approximately 1-acre Site was operated as a service garage and gas station from ca to 1998, most recently by Keith Schoppee, the late husband of the Site owner, Bessie Schoppee. The Site contains an abandoned garage with a collapsed roof that contains various automotive servicing supplies and equipment, including apparent used motor oil, a 275- gallon above ground storage tank (AST), and two antique automobiles. An open-walled storage area for propane cylinders with a propane dispenser, several cylinders, a large exterior propane tank, and a disconnected fuel pump are located southwest of the garage toward the river. The grounds surrounding the garage contain scrap metal, two fuel storage tanks (apparently empty), a 55-gallon drum, and other debris. The Site has no water supply or septic system, and public water and sewer are not available in the Site vicinity. The 211 Phase I ESA revealed the operation of several underground gasoline storage tanks (USTs) at the Site, which have reportedly been removed. The most recent UST removal included two gasoline USTs and approximately 1,34 cubic yards of contaminated soil from the front (east) side of the garage building in Some contaminated soil could not be practically excavated from beneath the garage and under U.S. Route 1, and was left in place. The 211 Phase I ESA identified three Recognized Environmental Conditions (RECs) for the Site related to (1) petroleum impacts associated with the gasoline USTs; (2) unsecured containers of petroleum products and chemicals in the garage, and the potential for contamination under the garage; and (3) uncertainty surrounding past waste management and spills. In June of 211, representatives of the Site owner conducted limited removal and disposal of some hazardous materials in the garage previously identified in the 211 Phase I ESA through a Washington County hazardous waste collection program. GEI completed a Phase II ESA and Surface Coatings & Asbestos Containing Materials Survey on February 2 and May 1, 212, respectively. The Phase II ESA identified an approximately 2-inch-thick layer of apparent petroleum-impacted soil (i.e., weathered waste oil) near the northwestern corner of the garage (about.5 ft deep) and apparent fill near the garage, ranging from the surface to 7 ft deep. The Phase II ESA did not identify soils with petroleum, lead, or volatile organic compound (VOC) concentrations in excess of the Maine Department of Environmental Protection (DEP) Excavation and Construction Worker direct- GEI Consultants, Inc. iii

5 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 contact Remedial Action Guidelines (RAGs). The concentrations of several petroleum compounds, polycyclic aromatic hydrocarbons (PAHs), and lead exceeded at least the Residential, and typically the Park User, RAGs. Concentrations of petroleum hydrocarbons and VOCs were below laboratory detection limits in samples of on-site ground water and from a nearby private residential water supply well. Vapor-phase naphthalene was identified at a concentration in excess of the 213 Maine DEP Commercial Soil Gas Target (SGT) near the southern wall of the garage. Concentrations of some petroleum and chlorinated compounds exceeded the 213 Residential SGTs but were less than the Commercial SGTs. The lead and asbestos survey identified lead-based paint (LBP) on a majority of exterior surfaces on the garage and propane shed. Interior LBP was not identified. The survey did not identify friable asbestos-containing materials (ACM). Several non-friable asphalticbased materials (roofing, wall systems) and window caulking and glazing were assumed to be ACM without laboratory testing. During Site visits on May 6 and 13, 214, GEI observed similar conditions to those reported during the prior Phase I and Phase II ESAs. A REC is defined by ASTM International as a condition with the potential for a past, current, or future release of oil or hazardous materials (OHM) at a property. Based on our visit to the Site and our review of available records, we identified the following RECs for the Site: 1. Historic releases of petroleum at the Site with concentrations in soil and soil vapor that exceed health-based guidelines for long-term exposure; the releases appear to be associated with the former USTs and automotive service activities. 2. Contaminated soil, related to past garage operations, with concentrations of organic compounds and lead in excess of health-based guidelines for long-term exposure. 3. The presence of several unsecured containers of petroleum and other chemicals in the dilapidated garage building, and the potential for contamination under the garage from historic OHM releases. Concerns surrounding asbestos and LBP are outside the scope of a Phase I ESA under ASTM (Standard E ). However, the Phase II ESA indicated the presence of LBP and potential non-friable ACM on the garage building. Consistent with the Phase II ESA and Surface Coatings & ACM Survey, GEI recommends: disposal of remaining OHM inside the garage; development of a soil management plan for Site activities that may disturb impacted fill; incorporation of clean cover over impacted soil in future Site development scenarios; installation of vapor intrusion mitigation measures for future Site buildings (if proposed); recording of an environmental covenant on the Site property deed to acknowledge residual contamination; proper management of LBP and ACM; and enrollment in the Maine DEP Voluntary Response Action Program (VRAP).

6 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Purpose and Scope GEI Consultants, Inc. completed this Phase I Environmental Site Assessment (ESA) on behalf of the Washington County Council of Governments (WCCOG) for Schoppee s Garage in Jonesboro, Maine (Site). The purpose of this ESA was to evaluate the Site for possible Recognized Environmental Conditions (REC), defined by ASTM International (ASTM) as a condition with the potential for a past, current, or future release of oil or hazardous materials (OHM) at a property. 1.1 Scope In accordance with our contract with WCCOG dated November 1, 212, and ASTM Phase I ESA protocol, we: Reviewed records available and interviewed officials from the Town of Jonesboro (the prospective Site owner), the Site owner (Bessie Schoppee), and members of the Schoppee Family. Collected and reviewed available documents and maps regarding local geologic and hydrogeologic conditions for the Site Incorporated the findings of the prior Phase I and Phase II ESA reports by GEI. Reviewed the most recent Maine DEP Hazardous and Oil Spill System Online Report Service database and visited the DEP File Room regarding related files. Reviewed the federal National Priorities List (NPL) and list of Resource Conservation and Recovery Act (RCRA) Corrective Action (CORRACTS) sites within 1 mile of the Site. Reviewed state and federal databases to identify leaking underground storage tanks (LUSTs); leaking aboveground storage tanks (ASTs); landfill/solid waste disposal sites; Comprehensive Environmental Response, Compensation, and Liability Information System List (CERCLIS) sites; state-listed hazardous waste sites; RCRA treatment, storage, or disposal facilities (TSDF); and designated Brownfield sites within 1/2 mile of the Site. Reviewed the list of RCRA generators, Emergency Response Notification System (ERNS) reports, and state-registered underground storage tanks (USTs) for the Site and parcels abutting the Site. Visited the Site. GEI Consultants, Inc. 1

7 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Site Location and History 2.1 Site Location The Site is located on U.S. Route 1, on the northern shore of the Chandler River, in Jonesboro, Maine (Fig. 1). The Site contains a one-story wood-frame garage with wooden floors. The building is in very poor condition and was not entered during the Site visit due to its partially collapsed roof. An open-walled shed previously used for the filling and storage of propane cylinders is located southwest of the garage. The Site consists of two abutting parcels totaling approximately 1 acre and listed with the Town of Jonesboro Assessor s office as Lots 14 and 15 on Map 15 [1,2]. The garage appears to be on Lot 15, and the owner is listed as Bessie Schoppee. Mrs. Schoppee is the widow of the late owner and operator of the Site, Mr. Keith Schoppee, who inherited the property from his father, Harrison, in Harrison Schoppee, the original owner, opened the garage around The Site is in an area of mixed residential and commercial use. Abutting properties include (see Fig. 2): To the north: A wooded area, beyond which is a private residence and possible in-home business. To the east: U.S. Route 1, across which is the undeveloped northern shore and a tidal inlet of the Chandler River. To the south: The Chandler River, across which are several residences and small-scale commercial properties (e.g., telephone substation). To the west: An undeveloped wooded area along the Chandler River. 2.2 Site History Historical Uses, Underground Tanks and Ownership Information We relied on the Site history compiled in the 211 Phase I ESA, which included information from interviews with members of the Schoppee family, the 1998 UST removal report, DEP spill reports, and historical information from the Town of Jonesboro. The Site use did not change between our initial 211 Phase I ESA and this report. Additional information provided during 214 interviews with the Site owner (Bessie Schoppee) and others, and review of historical maps, photographs, and deed information is included below. GEI Consultants, Inc. 2

8 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Historical Uses The most recent commercial use of the Site was as a service garage and gas station in operation since ca The garage closed in Work performed at the garage included automotive repair. Few details are known about the Site prior to ca. 1936, when the service station at the Site reportedly became operational. A U.S. Geological Survey (USGS) topographic quadrangle from 1921 does not appear to show structures on the Site, and an 1861 atlas indicated the Site location was undeveloped. According to information from the Town of Jonesboro and the Schoppee Family, Schoppee s Garage was operated ca to 1932 on the opposite shore of the Chandler River [1]. The structure was moved to its present location ca after completion of the present-day Route 1 bridge over the Chandler River. Based on review of the historic topographic maps, the presentday bridge is slightly east of the former bridge, and the current garage appears to lie along the approach to the former bridge. Underground Tanks Two gasoline USTs, their piping, and approximately 1,34 cubic yards of contaminated soil were removed from the front of the garage (facing U.S. Route 1) in April and May A 1,- gallon tank was reportedly installed in 1969 and had been inactive since ca Upon removal, it was reported as being in poor condition (rusted and pitted) with a 2.5- by 5-inch rectangular hole in its bottom, through which approximately 2 gallons of product escaped during removal. A 2,-gallon gasoline tank was reportedly installed in 1982 and had been inactive since October It was reportedly in good condition upon removal with little rust and no visible holes. The 2,-gallon UST replaced a 5-gallon UST; the installation date of the older tank was not identified. The former 5-gallon UST was removed in the 198s and reportedly remains in storage (above ground) on the Site. The 1,-gallon UST reportedly replaced a 275-gallon UST whose installation date was not identified. Ownership Information Based on a limited review of deed information for the Site, it appears Lot 15 (developed portion of Site) may have been owned by multiple parties (Bangor Hydro-Electric Company, now Emera Maine; Bert and/or Eugene Mawhinney) during the operation of the garage by Harrison Schoppee. Lot 15 appears to have been transferred by Warranty Deed from Harrison Schoppee to Keith Schoppee in March Lot 14 (undeveloped portion of the Site to the west) appears to have been acquired by Keith and Bessie Schoppee from Charlotte M. Dilworth in May Ms. Dilworth was identified in the Quitclaim Deed as a successor in interest to the Jonesboro Lumber Corporation. The updated ownership information obtained during this Phase I ESA is not expected to impact the overall conclusions and recommendations of the 211 Phase I ESA. GEI Consultants, Inc. 3

9 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Previous Investigations Four previous environmental investigations or reports were identified for the Site, the findings of which are summarized below. UST Site Assessment, Fessenden Geo-Environmental Services, June 16, 1998 The results of the UST Site Assessment were summarized above in Section and in the 211 Phase I ESA. Phase I ESA, GEI, February 3, 211 The Phase I identified three RECs, which included: 1. Past identification of petroleum-contaminated soil at the Site and the release of gasoline during UST removal. Removal of contaminated soil did not include impacted material from beneath the garage or U.S. Route The presence of several unsecured containers of petroleum and other chemicals in the dilapidated garage building, and the potential for contamination under the garage from historic OHM releases. 3. Uncertainty surrounding past waste management practices and potential spills during the Site s 6 years of operation as a gasoline filling station and service garage. In June of 211, representatives of the Site owner conducted limited removal and disposal of some hazardous materials in the garage previously identified in the 211 Phase I ESA in coordination with a Washington County hazardous waste collection program. Phase II ESA, GEI, February 2, 212 As follow-up to the Phase I RECs, GEI, Maine DEP, and subcontractors completed a Phase II ESA in February 212 [3]. As part of this Phase I ESA, we reviewed the environmental data compiled during the Phase II ESA and compared the results to the most-recent published DEP guidance, Maine Remedial Action Guidelines (RAGs) for Sites Contaminated with Hazardous Materials, dated May 8, 213. The changes primarily affected the evaluation of soil vapor data. The incorporation of the revised DEP guidance did not affect the overall findings and recommendations of the Phase II ESA but may impact the evaluation of remedial options and risk-based exposure during Site remediation planning. The Phase II ESA findings are summarized below. Soil: The Phase II ESA identified an approximately 2-inch-thick layer of apparent petroleumimpacted soil (i.e., weathered waste oil) near the northwestern corner of the garage (about.5 ft deep) and apparent fill in the investigations completed near the garage building, ranging from the surface to 7 ft deep. Contamination observed in the on-site fill appeared to be related to past garage operations and was limited in extent (within about 1 ft or less from the garage). The GEI Consultants, Inc. 4

10 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Phase II ESA did not identify soils with petroleum, lead, or VOC concentrations in excess of the Maine Department of Environmental Protection (DEP) Excavation and Construction Worker direct-contact Remedial Action Guidelines (RAGs). The concentrations of several petroleum compounds, polycyclic aromatic hydrocarbons (PAHs), and lead exceeded at least the Residential, and typically the Park User, RAGs. The concentration of one PAH also exceeded the Outdoor Commercial Worker (OCW) RAG at several locations near the garage. Petroleum compounds exceeded the Leaching to Ground Water RAG at several locations. In the area of the apparent petroleum-impacted soil near the northwestern corner of the garage, concentrations of several petroleum constituents, including PAHs, exceeded RAGs for Residential and Park User direct contact and background concentrations for rural Maine soils. The concentration of lead exceeded the Residential RAG but was less than the Park User RAG. The concentration of one PAH, benzo(a)pyrene also exceeded the OCW RAG. The impacted soil appeared limited in extent but may extend beneath the garage. Testing of fill material near the southern end of the garage indicated concentrations of petroleum compounds and PAHs in excess of the Residential and Park User direct-contact RAGs, and above concentrations detected in background soils. Benzo(a)pyrene concentrations also exceeded the OCW RAG. Soil Vapor: Vapor-phase naphthalene was identified at a concentration in excess of the 213 Maine DEP Commercial Soil Gas Target (SGT) near the southern wall of the garage. The concentrations of C9 to C12 hydrocarbons near the southern garage wall exceeded the 213 Residential SGT but were less than the Commercial SGT. Near the former USTs, the concentrations of two chlorinated compounds (carbon tetrachloride and chloroform) exceeded the 213 Residential SGT but were less than the Commercial SGT. Ground Water: Groundwater on the Site and at a nearby private residential water supply well exhibited no odor, sheen, or phase-separated petroleum product. Concentrations of petroleum hydrocarbons, volatile organic compounds (VOCs), and ethylene dibromide (EDB) were below laboratory detection limits in all samples. Polychlorinated Biphenyls (PCBs): Wipe samples collected from various oily or stained surfaces inside the garage were tested for PCBs. PCBs were below laboratory detection limits in all samples collected from the interior surfaces of the building. The Phase II ESA concluded that impacted soils at the Site did not appear to pose a significant health risk under current Site conditions. The report noted that risk of exposure would increase during excavation at the Site or removal of the garage where pockets of petroleum-impacted soil might be encountered. Vapor intrusion could be a risk for new construction at the Site without mitigation. GEI Consultants, Inc. 5

11 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 The Phase II ESA included the following recommendations: 1. Proper disposal of remaining oil and hazardous materials inside the garage. 2. Development of a soil management plan for Site activities that involve disturbance of fill material that may be impacted by lead, petroleum, or other compounds. 3. In the event of future Site development, covering impacted soils with clean fill and grass cover. 4. Should future site development include construction of a building, install vapor intrusion mitigation measures, such as a vapor barrier or sub-grade vent piping. 5. Recording of an environmental covenant on the Site property deed which notifies future owners of the presence of impacted soils and soil gas, at a minimum. 6. Submit an application to the Maine DEP Voluntary Response Action Program (VRAP). Once the application is approved, Maine DEP would issue a No Action Assurance letter contingent on implementation of any recommended response measures. The Site owner would be required to provide Maine DEP documentation that the response measures were implemented. Once implemented, Maine DEP would issue a Certificate of Completion, documenting fulfillment of Site closure obligations. The Phase II ESA also indicated that if future development of the Site includes demolition of the former garage, a notice must be filed with Maine DEP and any asbestos-containing materials must be properly managed (see below). Surface Coatings & Asbestos Containing Materials Survey, GEI, May 1, 212 As part of the Phase II ESA, GEI completed a lead-paint and asbestos survey at the Site in May 212 [4]. The survey identified lead-based paint (LBP) on a majority of exterior painted surfaces on the garage and propane shed. Interior LBP was not identified. The survey did not identify friable asbestos-containing materials (ACM). Several non-friable asphaltic-based materials (roofing, wall systems) and window caulking and glazing were assumed to be ACM without laboratory testing. 2.3 Site Neighborhood The Site neighborhood along the Chandler River appears to have contained a mixture of commercial and residential properties since at least The primary commercial uses indicated on an 1861 atlas included a saw mill (abutting the Site to the west) and a grist mill (across the Chandler River and southwest of the Site) [2]. The 1861 atlas, along with USGS topographic maps from 1921 and 1942 indicate continued rural residential/commercial land use near the Site. GEI Consultants, Inc. 6

12 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 The Site building itself was located across the Chandler River and just south of the Site ca to 1932 [1]. The garage was operated as a filling station and service garage before being moved to its present location ca It is possible that the former saw mill property west of the Site contains fill placed to support development along the shore of the river. Such fill may consist of wood, combustion byproducts, or other materials. Given the vegetative cover on the former mill property and the western portion of the Site, and lack of obvious evidence of environmental impacts (odors, stained soils, stressed vegetation) near the western Site boundary, it appears unlikely that the property poses a significant environmental risk to the Site. Based on the distance and location along the Chandler River, other historical uses in the Site neighborhood do not appear to pose a significant environmental risk to the Site. GEI Consultants, Inc. 7

13 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Site Visit and Description GEI visited the Site on May 6 and 13, 214, to observe and document property conditions, including evidence related to the potential presence of OHM [5]. Photos taken during our visit are included in Appendix A. A Site plan is shown on Fig. 2. We did not identify significant changes to the Site or adjacent properties, relative to the observations reported in the 211 Phase I ESA. Relatively minor changes observed during the 214 Site visit, such as scrap metal and waste organization, are described below in Section Site Description Former Garage Area The garage has a footprint of approximately 24 ft by 6 ft and is in poor condition with a collapsed roof. Photographs of the interior of the garage (taken through windows from the outside) are included in Appendix A. The interior layout and contents of the garage appeared similar to that observed in the 211 Phase I ESA and Phase II ESA. The interior of the garage appears to be separated into two main areas. A supply room (approximately 1 ft by 2 ft) occupies the northeast corner of the garage. It has tables and shelves containing various automotive maintenance supplies, cleaners, paint, and other debris. The rest of the garage appears to be an open bay. The garage bay contains two antique automobiles, a 275-gallon AST with unknown contents, at least two 55-gallon drums with unknown contents, a compressed gas cylinder, and twelve or more 5-gallon buckets, some of which contain apparent waste oil. Other debris includes pieces of the building itself (roof and walls), various automotive parts, and trash. Outside the building, a 275-gallon AST and 55-gallon drum were observed along the back (western) wall of the garage; the containers were closed and appeared to contain little, if any, contents. We observed apparent scrap metal near the back wall of the garage. We observed a pile of scrap metal and other solid debris (e.g., tires, wood) just north of the garage. The materials appear to have been consolidated from the rear of the garage and other smaller piles since our last visit to the Site (ca. 212). A 5-gallon fuel storage tank was noted southwest of the garage. The storage tank sidewalls were rusty and pitted with no obvious holes. The tank was reportedly a former gasoline UST on the Site that was removed in the 198s and replaced by the 2,-gallon UST removed in We observed a 1-pound metal propane tank near the former UST during the 211 Phase I Site visit; the tank was not observed during the 214 Site visit. GEI Consultants, Inc. 8

14 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Former Propane Filling Station The propane shed has a footprint of about 12 ft by 12 ft and lies approximately 25 ft southwest of the garage. The shed has wood floors, open wire mesh and timber-framed walls, and a sloped roof. The shed contained a 1-pound capacity propane cylinder, a 2-pound propane cylinder, an apparent propane dispenser, a scale, and a disconnected gasoline pump. Additionally, the shed contained various pieces of rusty metal scrap and what appeared to be heating or ventilation system components. A large propane tank (5 to 1, gallons capacity; approximately 1 to 15 ft in length) was located next to the southern wall of the shed. The tank surface was rusty. The prior Phase I ESA indicated that a second tank (of similar size but newer and in better condition) was located nearby. Michael Schoppee indicated the second tank had been removed by its owner (Kelley Oil) [3]. The tanks were reportedly used for filling smaller cylinders in the shed for commercial resale Observed Site Boundary The Site is bounded to the north and west by a steeply upward sloping wooded area; to the east by U.S. Route 1; and to the south by the Chandler River. Observed Site boundaries were approximate given that a boundary survey map was not available for the Site. Additional observations of adjacent properties are included in Section Site Utilities and Waste Management We did not identify significant new information or changes in the status of Site utilities and waste management. We observed evidence of limited solid waste and scrap metal clean-up and consolidation during our May 214 Site visits. We did not observe the overturned trash drum that was noted during the 211 Phase I ESA, and some of the scrap metal and other debris previously observed in the rear of the garage (western wall) appears to have been consolidated in a pile just north of the garage. We did not observe evidence of a water supply well or septic disposal system. This finding is consistent with reports that the Site had no water or sewer utilities. According to a 1989 Maine DEP spill report and Michael Schoppee [1], waste oil was disposed of at the nearby Blue Bird Ranch in a waste-oil furnace; the sources did not identify how long this disposal practice occurred. Mr. Schoppee estimated that the garage produced approximately 1 gallons of waste oil per year. GEI Consultants, Inc. 9

15 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Adjacent Properties The Site is bounded by public roads to the north (Whitney Road) and east (Route 1). An apparent residence (with combined in-home business) and cemetery are located across Whitney Road to the north. We observed two residences, a general store, a park, and a former Grange Hall northeast of the Site along Route 1. Across Route 1 to the east, we observed the undeveloped northern shore and a tidal inlet of the Chandler River. We also observed a small structure and overhead power lines on a parcel of land just north of the river shoreline. The area could be a former camping area, seasonal hook-up for a recreational vehicle, or former residence. The Chandler River forms the Site s southern boundary, and mostly undeveloped woodland borders the Site to the west. We observed the remains of a reported lumber mill (mostly bricks) west of the Site along the shore of the river. We observed a mix of residential and commercial (telephone facility) properties across the Chandler River to the south of the Site. Based on observations of the adjacent properties from the Site boundary and public rights-ofway, we observed no obvious evidence of leaks or spills of oil or hazardous materials on these properties.

16 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Environmental Setting 4.1 Surface Topography We primarily relied on information contained in the 211 Phase I ESA and observations from the Phase II ESA regarding Site topography, geology, and hydrogeology. New database searches for wells in the area were performed by GEI to update existing information. The Site is relatively flat near the garage and propane shed with an elevation of approximately 15 ft above mean sea level (msl). The Site slopes downward toward the Chandler River to the south, which lies at an elevation of approximately 11 ft above msl. The northwest boundary of the Site slopes steeply upward toward Whitney Road, which lies at an elevation of approximately 4 ft above msl (Fig. 1). 4.2 Geologic Setting Soils observed during the Phase II ESA were generally indicative of on-site filling with sand and gravel and miscellaneous fill material, as a result of the 1998 UST removal and prior Site work, respectively. Surficial geologic mapping by the Maine Geological Survey (MGS) indicated the Site is underlain by glacial marine deposits of the Presumpscot Formation, commonly a clayey silt with occasional localized sand, gravel, and till deposits. According to the State Geological Map of Maine, the Site is underlain by the Jonesboro Granite, a Devonian pink, two-feldspar biotite granite. We observed no obvious bedrock outcrops at the Site. During the Phase II ESA, bedrock was observed from approximately 5 to 8 ft deep just north of the garage. Bedrock was not encountered south of the garage to at least 8 ft deep. Depth to bedrock near the former USTs was inferred from the 1998 UST Site assessment to be approximately 1 to 13 ft below ground surface. Evidence of filling was observed during the Phase II ESA at most exploration locations near the garage. The fill depth ranged from near the ground surface to about 7 ft deep. The thickest fill layers and petroleum odors appeared to be located near the southern end of the garage. The Phase II ESA identified an approximately 2-inch-thick layer of apparent petroleum-impacted soil (i.e., weathered waste oil) near the northwestern corner of the garage (about.5 ft deep). The impacted soil appeared limited in extent but may extend beneath the garage. 4.3 Hydrogeologic Setting The Site is not located on a Significant Sand and Gravel Aquifer. The closest Significant Sand and Gravel Aquifer is located about.6 miles north-northeast of the Site. Significant Sand and Gravel Aquifers are mapped by the MGS and have the potential to produce relatively high yields of ground water to supply wells. GEI Consultants, Inc. 11

17 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Relative water level elevations during the Phase II ESA indicated that ground water flows approximately southwest toward the Chandler River, consistent with Site topography. The depth to ground water ranged from approximately 3.6 ft to 4.5 ft below ground surface. The Site neighborhood is served by private supply wells, as public water utilities are not available in the Site vicinity. Two private supply wells were observed at the residences located immediately north of the Site along Route 1. The Phase II ESA included testing of one of the nearby supply wells, which indicated no petroleum or VOC impacts above laboratory detection limits. We identified two public water supply wells within 1 mile of the Site, according to the Maine DEP public water supply database. A well serving the Chandler River Lodge is located approximately.5 miles northeast of the Site and apparently upgradient. A well serving Jonesboro Elementary School is located approximately.6 miles southwest of the Site, across the Chandler River. The MGS well database indicated several supply wells within approximately 2,5 ft of the Site. Most supply wells appear to be upgradient, cross-gradient, or hydraulically isolated (i.e., across the Chandler River) from the Site. A portion of the Site appears to lie along the fringe of mapped wetlands based on the National Wetlands Inventory Map, and is reported to lie within the 1-year flood zone as mapped by the Federal Emergency Management Agency (FEMA) [6].

18 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Interviews and Records Review 5.1 Municipal Interviews and Records Review GEI reviewed the original Phase I ESA and also inquired with the Site owner (Bessie Schoppee) and officials from the Town of Jonesboro regarding changes to Site status since the 211 Phase I ESA [7]. The information obtained from the research is incorporated herein. We relied on tax information reported in the prior Phase I ESA. We did not identify changes in ownership status since 211, based on our 214 interviews [7]. The 211 Phase I ESA indicated that the Jonesboro Volunteer Fire Department Chief, Michael Schoppee, recalled a fire in the garage in the mid-196s. The gas tank in a car inside the garage caught fire, but the fire was contained and caused little damage to the Site. We did not identify new information or significant changes at the Site (since 211) based on our 214 interview with Chief Schoppee [7]. We performed a limited review of selected deed records for the Site from the Washington County Registry of Deeds. We included this information in Section Other Town records contained information consistent with the operational history of the Site described elsewhere in this report. We did not identify new information for the Site that is likely to impact the conclusions of the original Phase I ESA or Phase II ESA. 5.2 State and Federal Document Review Environmental Data Resources Database EDR generated a database summary report of state and federal databases [6]. The full database report is included in Appendix B. The Site was identified in the UST, LUST, Recovered Government Archive (RGA) LUST, UIC, ALLSITES, Brownfields, and FINDS databases. The Site was identified by EDR as an ALLSITES, Brownfields, and FINDS property, based on its enrollment in the EPA/WCCOG Brownfields program. Information reported by EDR regarding the Site USTs is consistent with that detailed elsewhere in this report. The underground injection control (UIC) listing may refer to floor drains or monitoring wells on the Site. Information regarding the Site s enrollment in the Brownfields program (i.e., previous environmental assessments) and UST removal activities has been incorporated herein. Details regarding other database results (tanks and spills) for the Site are included in Section GEI Consultants, Inc. 13

19 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 A summary of the EDR report findings for properties in the Site vicinity is provided in Table 1. None of the properties identified by EDR appear likely to impact the Site based on regulatory status, distance from the Site, or apparent ground water flow direction (hydraulic gradient). This is consistent with the findings of the 211 Phase I ESA. GEI Consultants, Inc. 14

EDR Database Report Summary Not Including Target Property Database Underground Storage Tanks (USTs) Leaking USTs (LUSTs) Leaking ASTs (LASTs) Number of Sites Number reported < 1/8 mile Comments on Potential Site Impact 5 4 The UST locations appear to be incorrectly mapped in the EDR report as being very near the Site (likely due to insufficient address information along Route 1); we did not identify obvious evidence that the UST locations would have adverse impacts on the Site given their distance and regulatory status. 4 3 Gay Bros. Fruit and Produce, the DOT Maintenance Facility, and the Blueberry Hill Research Facility are incorrectly mapped in the EDR report; their apparent locations are greater than.7 miles from the Site, or in the case of Gay Bros., across the Chandler River; impacts to the Site are unlikely given distance, regulatory status, and/or apparent hydraulic gradient. 3 1 C.F. Look Construction is incorrectly mapped in the EDR report; its apparent location is greater than.3 mile from the Site; impacts to the Site are unlikely given distance, nature of release, and regulatory status.

21 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Orphan Sites Orphan sites are areas identified by the EDR search as potential sources of OHM but are not necessarily located within the search radius. They were not mapped by the EDR search because they lack sufficient address information. Nine such sites are included in this EDR report. Online searches for locations of the orphan sites, along with available regulatory information, yielded no clear evidence that any would likely act as an OHM source for the Site Maine DEP Database Reviews We searched publicly-available Maine DEP online databases for information regarding the Site and nearby properties on May 21, 214 [8]. The databases reviewed by GEI included the Maine DEP Hazardous and Oil Spill System Online Report Service, which lists spills and contains associated spill reports documented by the Maine DEP; the Maine DEP Oil Storage Tank database; the Maine DEP Sites List Database; and the Maine DEP File Room Database. The results were consistent with those included in the 211 Phase I ESA. We identified additional regulatory information for the Site regarding its enrollment in the Brownfields program in 211 (e.g., additional File Room files, listing on the Sites List). Maine DEP UST Database The Site is registered with Maine DEP as Facility Number Two gasoline USTs were removed in No other USTs are reported to be installed at the Site. The Site certificate was consistent with the information reported in Section Maine DEP Spill Reports We identified three spill reports for the Site, which is consistent with the findings of the 211 Phase I ESA. Only one of the three reports was identified by Maine DEP as a confirmed spill (B ; during the 1998 UST removal). The other two spill reports (B and B ) involved anonymous complaints that were not substantiated by Maine DEP personnel. Maine DEP Sites List The Site was listed on the Maine DEP Sites List as a Brownfields site with the status, Investigation in Progress. This is consistent with the project s current status in the WCCOG Brownfields program. GEI Consultants, Inc. 16

22 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, 214 Maine DEP File Room We searched the Maine DEP File Room online database and identified files previously reviewed by GEI during the 211 Phase I ESA and several new files that corresponded to the GEI Phase I and II reports. We did not visit the File Room in person because GEI prepared the reports identified as new since the original Phase I ESA User Information As required by ASTM Standard E , GEI inquired with Mr. Michael Schoppee, Jonesboro Selectman and son of the Site owner, about knowledge of environmental liens, activity and use limitations, specialized and common knowledge on environmental Site conditions, fair market value, and obvious indicators of contamination. The information provided by Mr. Schoppee was consistent with that included elsewhere in this report and the prior Phase I ESA. A copy of Mr. Schoppee s ASTM User Questionnaire is included in Appendix C. GEI Consultants, Inc. 17

23 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Summary 6.1 Opinion of Environmental Conditions GEI conducted a Phase I ESA on behalf of the WCCOG for Schoppee s Garage in Jonesboro, Maine. The Site consists of 2 lots totaling approximately 1 acre of land with a wooden garage in poor condition and a smaller wooden outbuilding previously used to store and distribute propane in a rural, mixed-use area near the Chandler River. GEI also performed a Phase I ESA, Phase II ESA, and Surface Coatings & Asbestos Containing Materials Survey for the Site in 211 and 212 (for WCCOG). A REC is defined by ASTM as a condition with the potential for a past, current, or future release of OHM at a property. Based on our visit to the Site and our review of available records, we identified the following RECs for the Site: 1. Historic releases of petroleum at the Site with concentrations in soil and soil vapor that exceed health-based guidelines for long-term exposure; the releases appear to be associated with the former USTs and automotive service activities. 2. Contaminated soil, related to past garage operations, with concentrations of organic compounds and lead in excess of health-based guidelines for long-term exposure. 3. The presence of several unsecured containers of petroleum and other chemicals in the dilapidated garage building, and the potential for contamination under the garage from historic OHM releases. Concerns surrounding asbestos and LBP are outside the scope of a Phase I ESA under ASTM (Standard E ). However, the Phase II ESA indicated the presence of LBP and potential ACM on the garage building. GEI Consultants, Inc. 18

24 ASTM Phase I Environmental Site Assessment Schoppee s Garage, U.S. Route 1, Jonesboro, ME June 17, Recommendations Consistent with the Phase II ESA and Surface Coatings & ACM Survey, GEI recommends: disposal of remaining OHM inside the garage; development of a soil management plan for Site activities that may disturb impacted fill; incorporation of clean cover over impacted soil in future Site development scenarios; installation of vapor intrusion mitigation measures for future Site buildings (if proposed); recording of an environmental covenant on the Site property deed to acknowledge residual contamination; proper management of LBP and ACM; and enrollment in the Maine DEP Voluntary Response Action Program (VRAP). 6.3 Data Gaps and Uncertainties The following data gaps and data uncertainties regarding the Site were identified during the process of performing the environmental site assessment: We could not determine the exact location of some of the releases that were listed as orphan sites in the EDR report. We were unable to access the interior of the garage and propane shed due to safety concerns. These data gaps and uncertainties are not expected to impact our conclusions. GEI Consultants, Inc. 19
