Site Description
Solvay Coke and Gas Site is located at 311 East Greenfield Avenue in Milwaukee, Milwaukee County, Wisconsin. The Site is approximately 46 acres in a primarily industrial and commercial area north of the Kinnickinnic River and west of the Lincoln Memorial Harbor. The Site is comprised of a number of lots, and various industrial activities have occurred on different lots since 1900 or maybe as early as 1866. A manufactured coke and gas facility located on the northern portion of the Site was operated by various entities until approximately 1983. The southernmost triangular tip of the property was occupied by several leather tannery companies starting approximately in 1884. Wisconsin Wrecking operated a scrap and salvage operation on the northern portion of Site until January 2003, when it assigned its interest in the Site to Water Street Holdings, LLC. Water Street Holdings, LLC, later conveyed the Site to Golden Marina Causeway, LLC.
Site Responsibility
The Site is being addressed through federal and potentially responsible parties (PRPs) actions.
Threats and Contaminants
In October 2001, U.S. EPA, Wisconsin Department of Natural Resources (WDNR), and the City of Milwaukee conducted a Site reconnaissance to evaluate site conditions to determine potential areas of contamination for sampling. In December 2001, U.S. EPA conducted a multimedia sampling event at the Site to screen for possible contamination and identify threats to human health and the environment. The Site Assessment Report dated May 1, 2002, summarize site conditions, threats to the public health or welfare or the environment, and actual or threatened releases of hazardous substances to the environment. Hazardous substances are located at the Site including: inorganics (antimony, arsenic, cadmium, chromium, copper, cyanide, lead, iron, mercury), asbestos containing material (ACM), benzene, carbazole, and polynuclear aromatic hydrocarbons (PAH) such as benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, fluoranthene, indeno(1,2,3-c,d)pyrene, phenanthrene, pyrene, and other organics (dibenzofuran and naphthalene).
In response to the conditions documented in the Site Assessment Report, U.S. EPA entered into the Removal Order with Cliffs Mining Company, Water Street Holdings, LLC, and Wisconsin Wrecking, LLC, to address four primary sources of hazardous substances: 1) asbestos containing material present in many of the structures, on piping inside and outside structures, and loose asbestos containing material located on the ground; 2) coal tar from the manufactured gas plant operations located in tanks, piping, on the ground, and in an open pit area; 3) numerous above ground storage tanks and associated piping containing coal tar and other residues; and 4) other hazardous substances located throughout the Site such as drums of naphthalene crystals and oil in old electrical transformers. The Removal Order did not require the investigation, sampling or excavation and removal of any subsurface hazardous substances or materials. Surface and subsurface contamination not addressed during the removal action remains and is a source of potential exposure to humans and wildlife. In addition, runoff from the Site could contain contaminated surface soil which could migrate off-site and enter the river at various locations. On September 6, 2005, U.S. EPA issued a Notice of Completion of On-Site Work for the Removal Order.
Cleanup Progress
An Administrative Settlement Agreement and Order on Consent (AOC) for Remedial Investigation/Feasibility Study (RI/FS) was entered voluntary by the Potenial Responsible Parties (PRPs) including American Natural Resources Company, Cliffs Mining Company, Maxus Energy Corporation, and Wisconsin Electric Power Company and Wisconsin Gas LLC (We Energies) in January 2007. East Greenfield Investors, LLC is participating in the agreement as a non-PRP Bonafide Prospective Purchaser. The PRPs and the East Greenfield Investors, LLC will conduct a RI/FS including a baseline risk assessment and ecological assessment at the Site.
