RI Pollutant Discharge Elimination System (RIPDES)
This is the backbone of the state's water pollution control strategy, which includes developing & enforcing permit limitations for municipal and industrial wastewaters, storm water, & combined sewer overflows discharged directly to the waters of the state, as well as industrial wastewaters discharged to municipally-owned treatment facilities. The program currently oversees permit compliance for 23 major discharges, approximately 70 minor discharges, & approximately 250 storm water discharges. The Pretreatment Program provides ongoing oversight of fifteen approved local pretreatment programs.
In accordance with the EPA Federal and RI Pretreatment Regulations, the 15 RIDEM-approved Industrial Pretreatment Programs regulate almost 200 Significant Industrial Users (SIUs) and thousands of Non-Significant Industrial Users. Over half of the state’s SIUs are subject to EPA Federal Categorical Pretreatment Standards.For more information on RIDEM’s Industrial Pretreatment Program, please contact Robert DiSaia at 401-222-4700, x-7228.
