Fact Sheet
October 2006
Record of Decision Issued - Iowa City Former Manufactured Gas Plant Superfund Site, Iowa City, Iowa
INTRODUCTION
The U.S. Environmental Protection Agency (EPA) has released a Record of Decision (ROD) that addresses contamination at the Iowa City Former Manufactured Gas Plant (FMGP) site in Iowa City, Iowa. This action is being taken under the Comprehensive Environmental Response, Compensation and Liability Act, also known as the Superfund law. The ROD was signed on September 26, 2006.
A public comment period ran from July 28 – August 27, 2006. EPA was available to take public comments on the Proposed Plan at a public meeting on August 9, 2006. EPA recommended specific actions in the Proposed Plan to address the site. EPA and the Iowa Department of Natural Resources concurred on the preferred alternative in the Proposed Plan.
After the comment period closed, EPA selected a remedy, as documented in the ROD. The ROD includes a summary of EPA’s responses to comments received during the public comment period.
ABOUT THE CONTAMINATION
Coal tar contaminants, such as polynuclear aromatic hydrocarbons; volatile organic compounds, including benzene and toluene; and cyanide have been identified in samples taken both onsite and offsite.
SELECTED REMEDY
The selected remedy is the preferred alternative in the Proposed Plan, which includes:
- Local ordinances and state rules governing ground water would be enhanced by environmental covenants to restrict land and ground water use at the site and in a portion of Ralston Creek adjacent to the site.
- Indoor air and sediment monitoring would be conducted.
- Ground water monitoring that would include analyses to ensure that bioremediation of ground water is occurring to limit contaminant migration.
- Removal and off site disposal of light nonaqueous phase liquid contamination from ground water.
