NPDES Stormwater ProgramHistoryIn 1972, The National Pollutant Discharge Elimination System (NPDES) program was established under authority of the federal Clean Water Act and then delegated to the Division of Water Quality for implementation in North Carolina. Phase I of the NPDES stormwater program was established in 1990, and it focused on site and operations planning to reduce pollutant sources. Phase I covered industrial activities in 10 cateogories; construction activities that disturbed five or more acres; and municipalities with populations of 100,000 or more that owned or operated a municipal separate storm sewer system (MS4) (North Carolina had six). Phase II of the program expanded permit requirements to construction disturbing an acre or more and to smaller communities (< 100,000 pop.) and public entities that own or operate an MS4. Phase II also expanded the option of the No Exposure Exclusion beyond the 'Light Industry' category. NPDES Stormwater Program Rules and LawsNPDES Stormwater Application Forms

No Exposure
Facilities with stormwater discharges "associated with industrial activity" may be excluded from permit coverage if industrial materials and operations are not exposed to stormwater. The facility must maintain this condition of no exposure to qualify for the permitting exclusion. If the condition changes, the facility must seek permit coverage for industrial stormwater discharge under a general or individual permit. The facility is responsible for recertifying every five years that the no exposure condition is being maintained.
The no exposure exemption is not available for construction activities covered under the NPDES stormwater program. See the following links for more detailed information on No Exposure:
