Stormwater Permitting Options for Industrial Facilities
Two types of NPDES industrial stormwater permits, general and individual permits, are available to operators of industrial facilities.
General Permits
Most industrial facilities have permit coverage under a general permit because it is the most efficient permit option. General permits contain requirements for numerous types of industrial activities, allowing a facility operator to quickly obtain permit coverage. Where EPA is the NPDES permitting authority, the Multi-Sector General Permit is the general permit currently available to facility operators. Other types of general permits may be available in NPDES authorized states; contact the appropriate NPDES permitting authority to obtain more information on general permits in these states.
Individual Permits
There are certain circumstances where a general permit is either not available or not applicable to a specific facility. In this type of situation, a facility operator must obtain coverage under an individual permit that the NPDES permitting authority will develop with requirements specific to the facility.
Multi-Sector General Permit (MSGP): Describes facilities eligible for coverage, permit requirements and application procedures.
Individual Permit: Describes when a facility operator may require coverage under this type of permit.
