Site Description[1] 
Location: The site is located in a mixed-use area of Brooklyn. It is bounded by Kent Ave. to the east, Wallabout Channel to the west, Division Ave. to the north, and the Brooklyn Navy Yard to the south. Site Features: The site is a currently vacant with no above grade structures on it. There is a large pit, used for ash storage in the northwest corner of the site. Current zoning/use. The site is zoned for industrial use, but is currently sitting vacant. It is surrounded by commercial and multiple occupancy residences. Historical Uses: The site was previously an electrical generating station and substation until the late 1990's. The site was razed to the ground from 2007 to 2009. The main sources of contamination are from the ash pit storage area and from by-products of the electrical generating process which are scattered across the site. At this time remedial investigation work has been performed to determing the nature and extent of contamination and an IRM is scheduled to empty and stabilize the ash pit. The site was recently added on to Con Edison's multi-site Voluntary Cleanup Agreement and is now being administered out of the central office. Site geology and hydrogeology: The site is underlain by a 5 to 10 foot layer of fill and the far western edge is built out, on piles, over the bank of the Wallabout Channel. Under the fill are intermingled layers of silt and sand down to roughly 100 feet below grade. Beneath the silt and sand is a clay confining unit. Groundwater at the site is roughly 8' and is probably tidally influenced.

Summary of Project Completion Dates
Projects associated with this site are listed in the Project Completion Dates table and are grouped by Operable Unit (OU). A site can be divided into a number of operable units depending on the complexity of the site and the number of issues associated with a site. Sites are often divided into operable units based on the media to be addressed (such as groundwater or contaminated soil), geographic area, or other factors.

Site Environmental Assessment
Nature and Extent of contamination: The site is impacted by SVOCs, Metals, and PCBs, all by-products of the electrical generating and distribution that occurred on site. The contaminants are distributed across the site. There is also evidence of asbestos in the shallow subsurface. The site is also immediately adjacent to the former Nassau Manufactured Gas Plant and is likely impacted by that site as well. Special Resources Threatened: Given the site's location, adjacent to the Wallabout Channel, it is likely that contaminants have made their way into the channel.
