The Solvay Coke & Gas plant sits in a prime real-estate area of Milwaukee. The plant originally opened in 1906 and closed its doors in April, 1983. Plans to demolish the expansive site have been in the works for years, but the intensive cleanup efforts mandated by the EPA have put this plant in limbo. It is, after all, a Superfund site. Arsenic, lead, asbestos, and a whole host of other chemicals have been mixed into the ground.
