Future Plans for the Clinton Coal Gas Superfund Site, Clinton, Clinton County, Iowa


The U.S. Environmental Protection Agency (EPA) Region 7 has been overseeing site investigation and cleanup activities related to the coal tar contamination at the Clinton Coal Gas Superfund site (Site) in Clinton, Iowa. The Site is located on the west side of Riverview Park between Fourth Avenue North and Second Avenue South. 

The work is being performed by Interstate Power and Light Company (IPL), now a part of Alliant Energy, under an agreement called an Administrative Order. In addition to investigation work at the Site, IPL completed the removal and treatment of approximately 120,000 tons of soil contaminated with coal tar, lead, and polychlorinated byphenyls (PCBs).


IPL is completing the investigations and feasibility study of options to address the contamination that remains at the Site. EPA, in conjunction with the Iowa Department of Natural Resources (IDNR), has determined that IDNR would be in the best position to oversee the remaining actions that need to take place at the site.

IDNR and IPL will be working together in the next few months to reach an enforceable agreement for the completion of site cleanup activities. Once an agreement is in place the EPA will once again notify the public.  In the meantime, the EPA continues to oversee the activities at the Site.


EPA encourages the community to review the Administrative Record which contains information about past cleanup activities and next steps. The Administrative Record is available during normal business hours at the following locations:

EPA Records Center
901 N. Fifth St.
Kansas City, Kansas

Clinton Public Library
306 8th Avenue South
Clinton, Iowa


It is EPA’s commitment to keep the Clinton community informed about Site activities throughout the cleanup process. EPA is available to discuss and answer questions regarding the ongoing and planned response actions. If you have questions or need additional information, please contact:
