The City of Riverside has a National Pollutant Discharge Elimination System (NPDES) Permit issued by the Santa Ana Regional Water Quality Control Board to discharge wastewater from the Riverside Regional Water Quality Control Plant (Plant).
A component of the National Pollutant Discharge Elimination System (NPDES) Program, the National Pretreatment Program was developed by EPA to control the discharge of pollutants from POTWs. The statutory authority for the National Pretreatment Program lies in the Federal Water Pollution Control Act of 1972, which was amended by Congress in 1977 and renamed the Clean Water Act .
To meet the requirements of the 1977 amendments, EPA developed the General Pretreatment Regulations for Existing and New Sources of Pollution [40 Code of Federal Regulations (CFR) Part 403]. The National Pretreatment Program consists of three types of national pretreatment standards established by regulation that apply to industrial users (IUs). These include prohibited discharges, categorical standards, and local limits.
The Environmental Compliance Section derives its authority from the Riverside Municipal Code 14.12. This ordinance is used to determine an industry's compliance with pretreatment regulations.
