Stormwater permits issued by NDEP are implemented based on Best Management Practices (BMPs) such as diversion, detention, erosion control, sediment traps, gravel construction entrances, covered storage, spill response, and good housekeeping. Site operators (permittees) select the BMPs subject to approval by NDEP.
A stormwater permit is required under NDEP's general permit NVR100000 for stormwater discharge associated with construction activity, that:
- Will disturb one or more acres of land; or
- Will disturb less than one acre but is part of a larger common plan of development or sale whose total land disturbing activities total greater than one acre (or is designated by the NPDES permitting authority); and
- Will discharge stormwater runoff from the construction site to an MS4 (municipal separate storm sewer systems) or waters of the U.S.
How to Obtain a Stormwater Construction Permit: A permit is obtained by completing an on-line application (Notice of Intent -NOI) along with submission of the permit filing fee, no later than two (2) days prior to the start of construction. Provisional authorization begins 24 hours following receipt of the electronic NOI by NDEP.
After completion of the electronic NOI, the applicant submits a signed/dated certification statement and applicable filing fee to NDEP.
Once the signed certification statement and fee are received by NDEP, an authorization letter is sent to the general permit holder for their files. During the period beginning on the authorization date and lasting until permit coverage is terminated, the Permittee is authorized to discharge:
- Stormwater Associated with Construction Activity, or
- Stormwater Associated with Small Construction Activity, and
- Stormwater Associated with Industrial Activity from temporary concrete, asphalt, and material plants or operations dedicated to the permitted construction project, to Waters of the State in accordance with the Stormwater Pollution Prevention Plan and the conditions of the permit.
