1987-1992 five categories of stormwater discharges,
considered
to represent the most significant stormwater sources
of pollution, were subject to immediate permitting:
Facilities already covered by an NPDES permit for
stormwater
Facilities that engage in industrial activity (including
heavy manufacturing facilities, large construction
sites, and transportation facilities, among others)

Large (>250,000 population) municipal separate storm
drains systems
Medium (100,000> population <250,000) municipal

have stormwater discharges contributing to a
violation of water quality, or that are "significant
contributors" of
pollutants to waters of the United States
