The 11 categories are defined using both narrative descriptions of the activities and Standard Industrial Classification (SIC) codes. (Note: The North American Industry Classification System (NAICS) will eventually replace the SIC system. The U.S. Bureau of the Census has a conversion table to bridge the two systems.)
Multi-Sector Generic Permit (MSGP) Requirements
A generic permit is a general permit issued by DEP under the authority of section 403.0885, Florida Statutes, which is the provision authorizing the state to implement the NPDES program. In October 2000, Florida adopted under Rule 62-621.300(5)(a), F.A.C., the federal stormwater multi-sector general permit for industrial activities (comprising the original Sept. 29, 1995, issuance and subsequent corrections/modifications) and operates the permit as the state of Florida Multi-Sector Generic Permit for Stormwater Discharge Associated with Industrial Activity (MSGP).
The 11 categories of regulated industrial activities are further divided into 29 sectors with common activities, pollutant sources and associated pollutants.
A Stormwater Pollution Prevention Plan (SWPPP) must be developed, implemented and kept onsite. SWPPP guidance is available.
Analytical and Compliance monitoring data may be required by the permit. The results are submitted via the department’s online EzDMR System.
Compliance monitoring is required for five specific industrial activities whose stormwater discharges are subject to numeric stormwater effluent limitations.
Analytical monitoring is required only for the industry sectors or sub-sectors that were determined to have a high potential to discharge a pollutant(s) at concentrations of concern. The permit specifies benchmark values for industry-specific pollutants. Benchmark values are established to gauge the effectiveness of the SWPPP and determine whether there is a need to continue monitoring.
Visual monitoring is required of all facilities covered under the MSGP (except for Sector S - Air Transportation Facilities). Visual examinations must be performed at least once per quarter for the life of the permit and results shall be recorded in the SWPPP.
Facilities with industrial activities activities may qualify for an exemption from certain NPDES stormwater permitting requirements if all industrial materials or processes are protected by a storm-resistant structure.
Stormwater discharges from industrial activities that are not eligible for a generic permit must be covered under an individual permit with requirements specific to the facility (as specified under Rule 62-620, F.A.C.). Applications for individual NPDES stormwater permits for industrial activities, excluding steam electric power plants, should be sent to the Industrial Wastewater Section of the appropriate DEP regulatory district office.
The Florida Department of Environmental Protection is the state’s lead agency for environmental management and stewardship – protecting our air, water and land. The vision of the Florida Department of Environmental Protection is to create strong community partnerships, safeguard Florida’s natural resources and enhance its ecosystems.
