    EXECUTIVE SUMMARY

    The following report presents the findings of a Phase I Environmental Site Assessment (ESA) performed by Ransom Consultants, Inc. (Ransom) for the FPL Energy Maine Hydro, LLC Parcel located on Laconia Street in Biddeford, York County, Maine and referenced by the City of Biddeford Assessors Office as Map 71, Lot 8 (the Site). This Phase I ESA was performed in general accordance with the requirements of the American Society for Testing and Materials (ASTM) International Designation: E 1527-05, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process, which meets the requirements of the United States Environmental Protection Agency (EPA) All Appropriate Inquiry (AAI), 40 CFR Part 312 . The purpose of this Phase I ESA was to document the environmental history of the Site, evaluate the likelihood that a release of oil and/or hazardous material (OHM) has occurred or has the potential to impact the Site, and to provide our professional opinion regarding evidence of Recognized Environmental Conditions (RECs) in connection with the Site.

    The Site, located on the western bank of the Saco River, is currently vacant. It is abutted on the remaining three sides by former mill buildings, which have or are currently being redeveloped as mixed-use commercial/residential space. Based on available information, the Site was formerly utilized as part of the River Dam Mill. From the late 1800s until the mid/late 1900s, the Site was developed with mill structures and may have been used for storage, production, or transportation of goods. A machine shop was also formerly located in the southern portion of the Site. According to City personnel, in the late 1900s, the Site may have been used by Central Maine Power (CMP) to store electrical transformers. The Subject Area has been used for industrial purposes, since its development in the 1800s. Area buildings are connected to municipal water and sewer, provided by the City of Biddeford.

    As part of Ransoms assessment of the Site, Environmental Data Resources, Inc. (EDR) conducted an environmental database search. Ransom also reviewed the Maine Department of Environmental Protection (MEDEP) online databases. The Site was not identified in the EDR Report; nor was it identified in any MEDEP online databases.

    The three adjacent properties located west, north, and south of the Site have historically been industrial/mill sites: the former River Dam Mill (up and side-gradient), former WestPoint Stevens Mill Building 11 (up and side-gradient), and North Dam Mill, formerly part of the WestPoint Stevens Mill complex (side-gradient). Although remediation activities in accordance with the MEDEP Voluntary Response Action Program (VRAP) are in various stages for these three properties; the historic use, storage, and possible releases of oil and/or hazardous materials at the up-gradient River Dam Mill and WestPoint Stevens Mill properties may have had the potential to adversely impact the Site. Subsurface investigations completed at the River Dam Mill have revealed heavy metals, semi-volatile organic compounds (SVOCs), benzo(a)pyrene, and diesel range organics (DRO) in surficial and subsurface soil samples at concentrations above applicable MEDEP Remedial Action Guidelines and/or Cleanup Goals. Historic environmental investigations at the WestPoint Stevens Mill have previously documented the use and/or release of several chemicals including DRO, volatile organic compounds, chlorinated solvents (trichloroethylene and its degradation products), polycyclic aromatic hydrocarbons (PAHs), and metals.

    We have performed a Phase I ESA in general conformance with the scope and limitations of ASTM Practice E 1527-05 and Ransoms Scope of Work, dated August 31, 2011, for the property identified by the City of Biddeford Assessors Office as Tax Map 71, Lot 8, located on Laconia Street in the City of Biddeford, York County, Maine. Any exceptions to, or deletions from, this practice are

    described in Section 1.4 of this report. Based on the information obtained during this Phase I ESA, Ransom has identified the following RECs in connection with the Site:

    1. Prior environmental investigations completed at adjacent and up-gradient properties (former River Dam Mill and WestPoint Stevens Mill) identified heavy metals, VOCs, SVOCs, DRO, PAHs, and DRO in surficial and subsurface soils at concentrations which exceed applicable MEDEP Remedial Action Guidelines and/or Cleanup Goals. Due to the fact that these investigations were completed directly up-gradient and in close proximity from the Site, it is likely that the surficial and/or subsurface conditions found at the River Dam and WestPoint Stevens properties are consistent with those found at the Site.

    2. City and FPL personnel indicated that CMP may have formerly stored electrical transformers on-Site. FPL indicated that an environmental report documenting potential environmental conditions, as a result of this activity may exist; however, FPL representatives were unable to locate a copy of the report for review as part of this assessment. Improperly stored transformers may represent the threat of release of polychlorinated biphenyls (PCBs) onto the surface or into the subsurface.

    3. Stormwater discharge pipes were observed in the central portion of the property. City personnel indicated that the stormwater from the adjacent mill complex(es) was collected and discharged onto the Site through this subsurface collection system. There is the potential that historic and existing spills, releases, and poor housekeeping practices at the adjacent mill facilities have allowed pollutants to be discharged through the stormwater collection system and onto the Site.

    Based on the information obtained during this assessment, Ransom concludes that additional investigation is warranted. Specifically, Ransom recommends the following:

    1. A limited subsurface and/or surface soil investigation should be performed to determine whether the Site has been impacted from historic industrial operations conducted on the site, historic industrial operations conducted on adjacent and up-gradient properties, the potential for releases associated with electrical transformers, which may have been historically stored on-Site, and the potential for releases associated with the stormwater discharge points on-Site.

    2. Prior to any site redevelopment activities, Ransom recommends the development of a Soil Management Plan to address necessary actions in the event contaminated soil is encountered during Site redevelopment.

    3. Depending on the results of the recommended limited subsurface and/or surficial soil investigation noted above, a deed restriction may need to be developed, requiring that certain site use conditions/covenants be imposed on the property, such as prohibiting/managing the excavation of on-Site soils and/or prohibiting groundwater extraction.

    4. The Site should be entered into the MEDEP VRAP. The VRAP would allow for MEDEP review and approval of the assessment actions performed, and assuming the MEDEP concurs with the actions conducted at the site, would provide for liability protection under 38 M.R.S.A. 342 (15) and 343-E. Upon submission of a Site Closure Report, and subsequent approval of the VRAP Application, the MEDEP would issue a No Further Action letter to the applicant.
