The U.S. Environmental Protection Agency (EPA) developed the federal
National Pollutant Discharge Elimination System (NPDES) stormwater
permitting program in two phases. Phase I, promulgated in 1990, addresses
the following sources:
- "Large" and "medium" municipal separate storm sewer systems (MS4s)
located in incorporated places and counties with populations of 100,000
or more, and
- Eleven categories of industrial activity, one of which is large
construction activity that disturbs 5 or more acres of land.
Phase II, promulgated in 1999, addresses additional sources, including
MS4s not regulated under Phase I, and small construction activity disturbing
between 1 and 5 acres.
In October 2000, EPA authorized the Florida Department of Environmental
Protection (DEP) to implement the NPDES stormwater permitting program in the
State of Florida (in all areas except Indian Country lands). DEP's authority
to administer the NPDES program is set forth in Section 403.0885, Florida Statutes (F.S.). The NPDES
stormwater program regulates point source discharges of stormwater into
surface waters of the State of Florida from certain municipal, industrial
and construction activities. As the NPDES stormwater permitting authority,
DEP is responsible for promulgating rules and issuing permits, managing and
reviewing permit applications, and performing compliance and enforcement
Important note: The NPDES stormwater permitting program is
separate from the State's
permitting programs authorized by
Part IV, Chapter 373, F.S.
(593 KB) and implemented by DEP and the water management districts using
and from local stormwater/water quality programs, which have their own
regulations and permitting requirements.
The sources of stormwater discharges regulated under the NPDES program
fall into three categories. Follow the links to the right for more
information on each.
