The HPI Chemical Products Superfund Removal Site encompasses
four former pesticide formulation and distribution facilities owned by HPI
Products in St. Joseph, Missouri. These facilities house thousands of
containers of pesticide and herbicide containing hazardous substances,
pollutants, and contaminants. EPA is currently conducting a cleanup of the
site, including characterizing and bulking these wastes for proper disposal.
To date, EPA has bulked and disposed of thousands of waste
containers at the site and inventoried tens of thousands in preparation for
The facility addresses in St. Joseph are as follows:
222 Sylvanie Street
317 West Florence Road
1421 South 11th Street
1301 South 11th Street
EPA began its involvement at the site in 2007 with the
Resource Conservation and Recovery Act (RCRA), which regulates active operating
facilities that generate hazardous waste. RCRA inspectors from EPA and the
Missouri Department of Natural Resources (MoDNR) discovered numerous violations
of RCRA regulations and attempted to bring the HPI facilities into regulatory
compliance though various enforcement mechanisms.
In 2022, a federal judge ordered HPI Products to stop
operations for failure to comply with previous efforts to resolve longstanding
violations of state and federal environmental laws.
In 2023, EPA’s RCRA program referred the HPI sites to EPA’s
Superfund Emergency Response and Removal program to assess and dispose of
wastes improperly stored at the site.
