A copy of the ROD entitled Record of Decision, Girard Point Management Area is presented in Appendix A. The selected remedy stipulated in the ROD included base-wide institutional controls that included prohibitive ground water use for human consumption, restrictive future use (i.e., no permanent residential uses), and specific restrictions on construction or development of an outdoor playground). In addition, the specific selected remedy for the GPMA included early removal actions at designated areas prior to remedial construction, construction of a vegetated soil' cover on approximately 21 acres of the 25-acre GPMA, construction of a bituminous concrete pavement cover on the remaining 4 acres, long-term shallow ground-water monitoring (LTM), establishment of site- specific institutional controls (i.e., deed notification prohibiting excavation without prior written approval by the Pennsylvania Department of Environmental Protection (PADEP), and five-year reviews to evaluate whether additional remedial actions are required. This initial five year review marks five years since issuance of the ROD. The review also coincides with the end of the first five- year monitoring period of the long-term ground-water monitoring. 1.2 Site Background The GPMA is a peninsula located in the northwest area of the Philadelphia Naval Business Center (formerly the Philadelphia Naval Base) at the confluence of the Schuylkill and Delaware Rivers as shown on Figures 1-1 and 1-2. The 1-95 Girard Point Bridge, spanning the Schuylkill River, passes directly over and bisects the site. The GPMA is a generally flat, vegetated/paved, 25-acre site historically used for the treatment, storage, and disposal of solid wastes generated at the Philadelphia Naval Base. Portions of the area were created by landfilling associated with these waste management activities. Landfills at the site contain construction debris, incinerator ash, suspected foundry slag/sand, spent blasting grit used for paint removal, and municipal waste, as well as, soil and fill materials (river dredge materials). Because the individual sites that comprise the GPMA share a similar site history and proposed future use, a Conceptual Site Model for the Girard Point Management Area (Stone & Webster, 1996) and a Site Characterization Report for the Girard Point Management Area (Stone & Webster, 1997b) were prepared to combine the available data, characterize the nature and extent of the site's constituents of potential concern (COPCs), and evaluate the risks posed by the site to the potential receptors. The proposed future use of the GPMA is currently as an 89-acre light industrial park, the Girard Point Industrial Park , consisting of warehousing and light industrial facilities. To evaluate the nature and extent of the COPCs at the site and the risk posed by the site to the potential receptors, GPMA was divided into two operable units: Zones A and B. Zone A consists of the two site landfills at Installation Restoration Program (IR) Sites 4 and 5. This zone covers an area of 11.2 acres and contains approximately 280,000 cubic yards of fill. Zone B consists of a former 1.25-acre Philadelphia Naval Business Center Girard Point Management Area Five Year Review div42\brac\042911850\task6A_5YEAR\FINALSYEARGPMA.doc Project J.O. 04291.18.50 Five-Year Review Revision: Final Page 2 transformer storage area (IR Site 3), a former 4-acre Resource Conservation and Recovery Act (RCRA) storage facility (the North West Parking Lot (NWPL)), the former Girard Point incinerator (Building 668), and a 7-acre area formally used to store spent blasting grit (referred to as the area west of the NWPL). Zone B covers an area of 13.2 acres and contains approximately 86,000 cubic yards of fill. The zones, as described above, were delineated for risk assessment purposes. Prior to issuance of the ROD, the site was divided into zones for purpose of remedial alternative discussion. This wifl be discussed further in Section 2.0. 1.3 Human Health and Ecological Risk Assessments Based on the human health and ecological risk assessments presented in the Site Characterization Report for the Girard Point Management Area, unacceptable risks were quantified for potential huftian receptors located in Zones A and B, and qualified for ecological receptors located throughout the GPp/LA (Stone & Webster, 1997b). The reader is directed to the Site Characterization Report for the Gir,ard Point Management Area (Stone & Webster, 1997b) for specific information on the human health and ecological risk assessments. A brief description is presented below. The quantitative human health risk assessment concluded that the following exposures resulted in risks above the United States Environmental Protection Agency (EPA) accepted risk levels for cancer and/or noncancer effects: Zone A ' • Incidental ingestion of and dermal contact with beryllium and copper in subsurface soil' by construction workers • Incidental ingestion of lead in subsurface soil by construction workers ZoneB • Dermal contact with polychlorinated biphenyls (PCBs) in surface soil by maintenance workers, occasional users/trespassers, and construction workers • Incidental ingestion of and dermal contact with 2,3,7,8-Tetrachlorodibenzofuran (TCDF) and beryllium in surface soil by maintenance workers • Incidental ingestion of lead in surface soil by maintenance workers, occasional users/trespassers, and construction workers • No unacceptable risk was estimated for exposures to COPCs in ground water. Incomplete exposure pathways were assumed for surface water and sediment and therefore no risks were estimated. It was noted in the Site Characterization Report for the Girard Point Management Area (Stone & Webster, 1997b) that asbestos was detected in Zones A and B, and although human health risk associated with asbestos cannot be quantified, the presence of asbestos fibers in soil poses potential risk
