    American Zinc and Chemical Site

    Beginning in 1913 through the late 1940s, American Zinc and Chemical Company owned and operated a 157-acre site in Smith Township, Washington County, which included a zinc smelter, acid plant, and residue mill. The company deep-mined coal onsite to supply the smelter operations and also disposed of various wastes onsite, which resulted in significant contamination of the soil, groundwater, wetlands, and Burgetts Fork, which borders the site and ultimately flows to the Ohio River.

    DEP found Cyprus Amax Minerals Company (Cyprus) to be a corporate successor responsible for the contamination and release of hazardous substances. Since 2009, DEP’s enforcement actions have led to successive settlements with Cyprus resulting in a phased cleanup of the site. Significant remediation has already been completed, and cleanup of the site is currently entering its final phase. DEP has secured $1.62 million from Cyprus Amax Minerals Company to address legacy pollution and will use the money to projects to benefit the environment in Washington County. The company will also pay $68,057 to reimburse DEP’s costs to assess and investigate the site.

    DEP will accept public comments on the Consent Order and Agreement until Tuesday, December 11, 2024. Comments may be submitted in writing to Paul Vogel, Manager, Hazardous Sites Cleanup, PA Department of Environmental Protection, 400 Waterfront Drive, Pittsburgh, PA 15222 or by emailing the Department at RA-EPSW-HSCA@pa.gov​.
