Under the NPDES
stormwater program, operators of large, medium and
regulated small municipal separate storm sewer systems (MS4s) require
authorization to discharge pollutants. Medium and large MS4 operators
are required to submit comprehensive permit applications and are
issued individual permits. Regulated small MS4 operators have the
option of choosing to be covered by an individual permit, a general
permit, or a modification of an existing Phase I MS4's individual
governments involved in construction projects will also need to
comply with stormwater construction rules.
regulations are federal rules, they are implemented by state
environmental agencies (except for Massachusetts, New Mexico, Alaska,
Idaho and New Hampshire where EPA retains authority).
