The NPDES Stormwater Permitting Program for MS4s exists to protect water quality by controlling pollutants carried by urban runoff. Rainwater can pick up debris, chemicals, and sediment from streets and parking lots, which MS4s discharge directly into rivers, lakes, and other waterways. The program requires municipalities to develop stormwater management plans, monitor water quality, and implement practices that reduce pollution. By doing so, it safeguards public health, preserves aquatic ecosystems, and promotes sustainable urban development.
For an MS4 to maintain Compliance:
- Develop, implement, and routinely update a Stormwater Management Program (SWMP) in compliance with FDEP NPDES MS4 permit requirements.
- Implement, maintain, and inspect best management practices (BMPs) across municipal operations, including streets, parks, utilities, fleet/yard facilities, and high-risk areas, as well as construction and post-construction sites.
- Conduct monitoring to identify and address illicit discharges and ensure BMP effectiveness.
- Provide public education, outreach, and clear signage on stormwater pollution prevention, tailored for Florida communities.
- Train municipal staff and contractors on stormwater pollution prevention, spill response, and BMP maintenance.
- Maintain comprehensive documentation of inspections, maintenance, corrective actions, training, spills, and monitoring to support annual FDEP reporting.
