The current mission of the Curtis Bay Coast Guard core industrial support for the USCG, including the design, construction, and repair of f. 3, p. 2 4). The Curtis Bay Coast Guard Yard was originally established in 1899 as a emy and boat repair facility. Industrial development began at the Yard around 1906. ad become a fully operational ship building and repair facility. The Yard reached its during WWII, with a civilian work force of more than 3,000. In 1941, a bulkhead er out into Curtis Creek. Three piers and two floating dry docks were built and s. The current waterfront configuration was essentially completed when d in the mid 1940s. Following WWII, the Yard workforce gradually declined. vessel repair and overhaul, buoy construction, and various manufacturing the 1960s and 1970s. Manufacturing operations were reduced at the Yard 1990s. Major activities in the 1990s centered around the construction of a (PA) was completed in 1993 at the Yard by Science Applications The PA identified 13 areas as potential sources of contamination. In supplemental information to the 1993 PA. The supplemental 3 sites as petroleum release sites that are exempt from CERCLA remaining areas of potential contamination were addressed in the Site e in 2000 by Tetra Tech NUS. Two of these areas (areas 6 and 13) are g System (HRS) scoring package because available data indicates amination associated with these sources. These two areas are further sources not scored section. Six of the nine areas of potential ,7, 8, 9, and 11, are included as sources in this HRS documentation sults collected from the six sources currently identified at the Yard indicate contamination le organic compounds (SVOCs), volatile organic compounds (VOCs) metals, biphenyls (PCBs), pesticides, and dioxins. The sources are not contained, therefore the tances are available to migrate into adjacent surface waters. The Curtis Bay Coast Guard adjacent to a documented fishery, Curtis Creek (Ref. 5). The Patapsco River and the , which are within the fifteen mile downstream target distance limit, are also designated , p. 5 2). The only fishery sampled to date is Curtis Creek.

This ; two underground storage tanks (USTs) that were used to store rinse water from a acid cleaning process. These tanks have been closed in place (filled with sand). There is no nce that leaks or spills have occurred at this location (Ref. 3, p 3 6). Soil sample results t no significant chemical contamination was present in this area (Ref. 3, pp. 6 42 and 6 43).

Sampling at these areas has substances that are available for migration into adjacent surface waters. These areas in the source description section and are identified in this HRS documentation to surface water sediment in Curtis Creek. PCBs were 1 , 2,3, and 6. Transformers and transformers oils, which 1 contributing to the PCB contamination in the soils. Waste Metals were documented in the observed release to surface water sediment. Elevated levels of metals were documented to be present at all source locations. The elevated levels of metals in the soils at the source areas are a ibutable to work operations performed in these areas that generate hazardous waste and the disposal of aste in these areas, Types of hazardous waste at the Yard include spent solvents and degreasers, ickel cadmium batteries, mercury batteries, lead acid batteries, lead paint dust, and incinerator ash (Ref. 3, p. 3 1,3 2,3 4).

An addition 1 source not defined in the source description section are USCG boats which were docked at the dry dock for various shipwork operations. These operations have resulted in the accumulation of contaminant such as carbon disulfide, 2 butanone, acetone, PCBs and metals present in the sediments in Curtis Creek (Ref. 4, p. 4 8 and Ref. 5).

(Ref. 3 , pp. USCG Yard to the site tc approximatt data from samples collected in surface waters both upstream and downstream of the Yard indicate that other sources of contamination may be present in the area Other known possible potential sources of contamination in the vicinity of the Road are Chemetals Corporation, a manganese ore processor, located adjacent Kellogg Corporation located to the west, and Baltimore Landfill, located north of the Yard (Ref. 3, p. 2 1).

 Ch Th (R( do we The potent w S = D : SWOF/ Environment Targets Wetlands occur along three surface water bodies within the 15 mile downstream target The length of these wetlands are provided below.

)sco River 'atapsco River is a tidally influenced freshwater moderate to large stream with an average flow f 280 cubic feet per second (Ref. 3, p. 5 1) The total length of wetland frontage subject to tial contamination located downstream along the Patapsco River, within the target distance is 1.4 miles, therefore the wetland assigned value is 50 (Ref. 1, sec. <IP_ADDRESS>.1 and Ref. 3,

8 ; p. 5 4, fig. 5 1).

apeake Bav :hesapeke Bay is classified as a coastal tidal water body as defined in the HRS final rule 1 , table 4 13). The total length of wetland frontage subject to potential contamination located stream along the Chesapeake Bay within the target distance limit is 0.9 miles, therefore the nd assigned value is 25 (Ref. 1, sec. <IP_ADDRESS>.1 and Ref. 3 , p. 5 3; p. 5 4, fig. 5 1).

contamination factor value (SP) is calculated as follows:

Value assigned for wetlands from HRS Table 4 24. 7alue assigned for the sensitive environment from H R S Table 4 23. Iilution weight assigned from HRS Table 4 13.
