Environmental Program & Public Education

City of Beloit's environmental staff oversees the City's Industrial Pretreatment Program (IPP). All wastewater treatment facilities that treat an average of five million gallons/day or more are required by the Environmental Protection Agency (EPA) to have an approved IPP. An IPP must include all federal regulations under 40 CFR 403 and state requirements under NR 211. In Wisconsin, the Wisconsin Department of Natural Resources (DNR) directly oversees the City’ s program.

Industrial Pretreatment Program

The Industrial Pretreatment Program was developed in order to prevent prohibited discharges from harming the Water Pollution Control Facility (WPCF), which protects the environment and public health. Prohibited discharges apply to all commercial and industrial users who are connected to the WPCF.
