Illicit Discharge Detection and Elimination: Program 3
The goal of SEMSWA's Illicit Discharge Detection and Elimination Program is to reduce the frequency and environmental impact of illicit discharges that are accidentally or intentionally discharged into the storm sewer system. The term “illicit discharge” is defined in the Colorado Department of Public Health and Environment- Water Quality Control Division’s Phase II Stormwater regulations as “any discharge to a municipal separate storm sewer that is not composed entirely of stormwater, except discharges pursuant to the Colorado Discharge Permit System (CDPS) permit and discharges resulting from fire-fighting activities." Since only stormwater is allowed in the municipal separate storm sewer system (MS4), all fluids that are not stormwater can be considered ‘harmful’ if are inadvertently leaked, spilled or dumped into the storm drain.
Illicit discharges enter the storm sewer system either through direct or indirect connections and contribute high levels of pollutants to receiving water bodies. SEMSWA strives to detect and eliminate illicit discharges with a regulatory mechanism that includes enforcement actions, procedures for tracing and removing the source, and training staff to detect pollutants. SEMSWA also relies on citizens to report inappropriate discharges
