U.S. Environmental Protection Agency Region 5 has proposed a $2.3 million cleanup plan for the Cedar Creek Mercury Marine Plant 2 Superfund site in Cedarburg, Wis. A comment period runs from Oct. 8 to Nov. 9. A public meeting where comments may be submitted orally or in writing will be held at 7 p.m., Wednesday, Oct. 10, at the Cedarburg City Hall Council Chambers, W63 N645 Washington Ave. PCBs from two local companies -- now-closed Amcast and Mercury Marine -- contaminated Cedar Creek (from below the Ruck Pond Dam to its intersection with the Milwaukee River), the Plant 2 property, the former Amcast property and some nearby private properties. EPA Superfund involvement at the site began in 2003. Mercury Marine and Wisconsin DNR began studying the site in 1983.
