Summary

Fifth Five-Year Review Completed

The U.S. Environmental Protection Agency (EPA) Region 7 has completed the Fifth Five-Year Review for the Peoples Natural Gas Superfund Site. Five-year reviews are required by the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) when hazardous substances remain on-site above levels that permit unrestricted use and unlimited exposure. Five-year reviews provide an opportunity to evaluate the site remedy to determine whether it remains protective of human health and the environment.

This Five-Year Review found that the remedy at the site is protective in the short-term because institutional controls are in place preventing unacceptable exposure to contaminants remaining on-site. The remedy will be protective in the long-term when it is determined whether the hydraulic containment system is capturing all contaminated groundwater moving from the site toward the Mississippi River. This Five-Year Review Report was signed Dec. 1, 2020.

EPA has assessed the ability of the public to access this Five-Year Review through an internet-based repository and has determined that the local community has this ability. As a result, the Administrative Records are available on EPA’s website (see Site Documents & Data).
