Stormwater Management
 In response to the 1987 Amendments to the Clean Water Act (CWA),
the U.S.
Environmental Protection Agency (EPA) developed Phase
I of the National Pollutant Discharge Elimination System
(NPDES) Storm Water Program in 1990. The Phase I program
addressed sources of storm water runoff that had the greatest
potential to negatively impact water quality. The Department
of Environmental Conservation (DEC) is responsible for administering
the program in NYS as part of the State Pollutant Discharge
Elimination System (SPDES). Under Phase I, SPDES permit coverage
was required for storm water discharges from medium and large
municipal separate storm sewer systems (MS4s) located in
incorporated places or counties, eleven categories of industrial
activity and construction activity that disturbed five or
more acres of land.
The Phase II Final Rule, published in the
Federal Register on December 8, 1999, expanded the stormwater
permit program to include stormwater discharges from certain
regulated small MS4s and construction activity that disturbs
between 1 and 5 acres of land. On January 8, 2003, the DEC
finalized two-new permits for stormwater discharges in NYS
as required by the Federal EPA; the small MS4 and small construction
permits.
