Public Notice: Northwestern States Portland Cement Co. Superfund Site, Mason City, Cerro Gordo County, Iowa
Sixth Five-Year Review Started
The U.S. Environmental Protection Agency (EPA) Region 7 has started the Sixth Five-Year Review for the Northwestern States Portland Cement Co. Superfund Site. Five-year reviews are required by the Comprehensive Environmental Response, Compensation and Liability Act 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 Report should be completed by July 2022.
EPA keeps site project information and reference materials for the public to read at information repositories. EPA assessed the ability of the public to access its online repository and determined that the local community has this ability. To review the previous Five-Year Reviews, Administrative Record, and other cleanup documents for this site, please visit EPA’s Site Profile Page (see Site Documents & Data).
