Overview of Storm Water Management Program Requirements
The national and state PDF storm water regulations now require certain small communities to obtain a National Pollutant Discharge Elimination System, also known as NPDES, permit. Missouri has three Phase I communities In addition, there are approximately 151 Missouri communities PDF affected by these Phase II storm water regulations These small communities with Municipal Separate Storm Sewer Systems, also known as MS4s, were required to obtain a NPDES permit by March 10, 2003 The permit requires these regulated MS4s to have their storm water management program in place by March 10, 2008 The program must address six minimum control measures The larger metropolitan areas such as Kansas City, Springfield and Independence became regulated under the 1990 Phase I regulations The Metropolitan St. Louis Sewer District successfully petitioned on behalf of the City of St. Louis to be regulated under Phase II.
Affected Missouri communities (medium and large MS4s) required to seek coverage under a NPDES permit
- Refer to state regulation 10 CSR 20-6.200 for application requirements for medium and large MS4s
Affected Missouri communities (small MS4s) required to seek coverage under a NPDES permit and develop a storm water management program.
- Federal criteria for determining which communities are affected.

- Metropolitan St. Louis Sewer District and their 60 co-permittees
- Permit options and reporting requirements – The Department issued a statewide general permit MO-R040000 PDF for Phase II MS4s on March 10, 2003 This general permit lists requirements for minimum control measures, reporting and monitoring The Department expects this general permit to cover the majority of Phase II regulated MS4s However, an alternative permit option is available. See Storm Water Program Guide For Phase II Communities of Missouri for more details.
