The NPDES Phase I required large jurisdictions to come into compliance with specific stormwater mandates. Phase II requires smaller jurisdictions, like Forest Park, to come into compliance by 2008. The mandate issued by the EPA is comprised of six Minimum Control Measures.
- Public Information and Education
- Each jurisdiction is required to educate the public about stormwater quality issues including erecting signs in major tributary crossings.
- Public Involvement and Participation
- Each jurisdiction must involve the public in stormwater projects, such as storm drain tagging and stream cleanups, and provide a way for the public to report stormwater problems.
- Illicit Discharge Detection
- Each jurisdiction must develop, implement, and enforce a program to detect and eliminate illicit discharges, develop a storm sewer map, and develop a map of all septic systems.
- Construction Site Stormwater Runoff Control
- Each jurisdiction must develop, implement, and enforce a program to address pollutants in stormwater runoff from construction activities.
- Post-Construction Stormwater Management
- Each jurisdiction must develop, implement, and enforce a program to address stormwater runoff from new development and redevelopment projects.
- Pollution Prevention/Good Housekeeping
- Each jurisdiction must develop and implement an operation and maintenance program, including training, to prevent or reduce pollutant runoff from municipal operations.
