Regulatory Guides: What's Included

  • 04 Water Management
  • 0402 Wastewater Discharge
  • 040206 Storm Water / Rain Water


Most storm water discharges are considered point sources and require coverage by a NPDES permit. In many cases storm water discharges can be covered by a general permit applicable to a category of dischargers rather than an individual permit. The primary method to control storm water discharges is through the use of best management practices (BMPs).

The NPDES storm water permit regulations promulgated by EPA cover the following classes of storm water discharges on a nationwide basis:

  • Operators of Municipal Separate Storm Sewer Systems (MS4s) located in 'urbanized areas' as delineated by the Bureau of the Census.
  • Industrial facilities in any of 11 listed categories that discharge to an MS4 or directly to waters of the United States. Facilities may certify to a condition of 'no exposure' if their industrial materials and operations are not exposed to storm water, thus eliminating the need to obtain storm water permit coverage. The affected industrial categories are: facilities with effluent limitations; manufacturing; mineral, metal, oil and gas; hazardous waste, treatment, or disposal facilities; landfills; recycling facilities; steam electric plants; transportation facilities; treatment works; construction activity; and light industrial activity.
  • Operators of construction activity that disturbs 1 or more acres land, including smaller sites if they are part of a larger plan of development.

Most states have authority to implement the NPDES permitting program, and therefore also have authority over storm water. However, EPA is the permitting authority in some areas, including Idaho, Massachusetts, New Hampshire, and New Mexico, Indian Country Lands, Puerto Rico, Washington, DC, and U.S. territories and protectorates. For federally regulated areas, EPA has developed two primary general permits - The multi-sector general permit (MSGP) and a general permit for construction activities. The MSGP regulates the discharge of storm water from an estimated 4100 industrial facilities in 29 different industrial sectors. The construction general permit covers 'land disturbing activities' that will disturb 1 or more acres of land, or will disturb less than 1 acre of land but is part of a common plan of development of sale that will ultimately disturb 1 or more acres of land.
