Program for Phase I Large & Medium MS4s - Permit Requirements


Florida's rules for medium and large MS4s can be found at Chapter 62-624, F.A.C.. The following provides a summary of the permit application requirements and program requirements.

Original Applications/Individual Permits

Phase I  large and medium MS4s were subject to the two-part permit application requirements found at 40 CFR 122.26(d). The fundamental portion of the application was the development of a proposed stormwater management program (SWMP) that would meet the standard of "reducing pollutants to the Maximum Extent Practicable (MEP)."  Upon approval, the NPDES permitting authority (EPA Region IV at the time) incorporated the SWMP into an individual permit which was then issued to the MS4 operator.  Stormwater management programs for Phase I large and medium MS4s include measures to:

  • Identify major outfalls and pollutant loadings
  • Detect and eliminate non-stormwater discharges to the system
  • Reduce pollutants in runoff from industrial, commercial, and residential areas
  • Control stormwater discharges from new development and redevelopment areas
  • Implement a monitoring program.

Annual Reports

According to Rule 62-624.600, F.A.C., each permittee is required to submit an annual report on


The MS4 individual permits expire after a term of five years. Permittees must re-apply for coverage prior to expiration of each permit term (see Rule 62-624.420). An MS4 permittee may re-apply for permit coverage concurrently with a timely filing of the fourth year annual report, or, as an alternative, permittees may re-apply by submitting an application 180 days prior to the expiration of the permit.  The required contents of a re-application are specified in Rule 62-624.440.
