Public Notice: EPA Begins Five-Year Review of Chem Central Superfund Site

Summary

U.S. Environmental Protection Agency (EPA) is conducting its sixth five-year review of the Chem Central Superfund site, located at 2940 Stafford Ave. in Wyoming, MI. The Superfund law requires regular checkups of sites that have been cleaned up to make sure that the cleanup continues to protect people and the environment. The review is expected to be completed in November 2024. 

The 2-acre site is a result of a 1957-1962 leak of industrial chemicals, which contaminated soil and groundwater. EPA’s cleanup of spilled industrial chemicals included collection and off-site disposal of chemicals, soil vapor extraction and groundwater pumping and treatment, and long-term monitoring.

EPA, working with the Michigan Department of Environment, Great Lakes, and Energy (EGLE), completed oversight for several rounds of vapor intrusion sampling at multiple properties in the vicinity of the Chem Central Superfund site from July 2018-April 2019. Sampling results, which show no immediate health threat, are available in this report; Vapor Intrusion Sampling Trip Report(PDF) (124 pp, 15.32 MB). In March 2023, the current site owner, Univar USA Inc., completed further vapor intrusion sampling onsite and to the north of the site above the groundwater contamination plumes that extend away from the original location. Sampling found no exceedances beyond health-based screening levels.  Results are available in this document: March 2023 Vapor Sampling Results (pdf) (346 pp, 14MB)
