Remediation work at the site of Mercury Marine’s decommissioned manufacturing plant in Cedarburg, Wisconsin, has been completed, and Mercury will, in partnership with the U.S. Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (WDNR), perform additional soil and sediment remediation work along the Cedar Creek Watershed. This work will be conducted in the stretch of Cedar Creek from the Ruck Pond dam to the creek’s confluence with the Milwaukee River.
After re-acquiring the Cedarburg Plant in 1993 (see Property History), Mercury Marine has remained committed to improving environmental conditions in the 5.2 miles of the Cedar Creek watershed while working closely with the WDNR and the EPA. From 1994 to 1996, Mercury Marine undertook a remediation initiative that focused on the removal of sediments containing PCBs in Ruck Pond. In 2000, Mercury Marine performed a similar remediation project to address PCB-containing soils within the floodplain of Hamilton Pond.
Mercury Marine, in partnership with the EPA, now is evaluating cleanup options to address the presence of PCBs in Columbia and Wire and Nail ponds, located immediately downstream of Ruck Pond. Ultimately, EPA will propose a cleanup for these areas, which will be described in a document that will be available to the public for comment. Whatever cleanup EPA ultimately selects will be funded and implemented by Mercury Marine.
Mercury Marine also continues its evaluation of the creek downstream of these ponds to its confluence with the Milwaukee River. Sediment and soil data will be collected this year. All sampling results will be provided to EPA for their evaluation.
