Steps to Authorization
In order to gain coverage under the SPDES General Permit for Stormwater Discharges from Construction Activity, an owner or operator must:
- Develop a Stormwater Pollution Prevention Plan (SWPPP) in accordance with the requirements in the General Permit for Stormwater Discharges from Construction Activity.
- Submit a completed Notice of Intent (PDF) (NOI) (219 kb) to the Department.
- Projects subject to MS4 regulation must submit a signed SWPPP Acceptance Form (PDF) (18 kb) along with their NOI. With some exceptions, an owner or operator of a construction project within the boundaries of an MS4 is required to have their SWPPP reviewed and accepted by the MS4 prior to submitting their NOI to the Department. Consult the Stormwater Interactive Map to determine whether your project is within an MS4. The map displays the automatically and additionally designated MS4 areas (regulated area). Some MS4s have extended their jurisdiction for SWPPP review to the municipal boundary; therefore, even if your project is located outside an MS4 regulated area, you should contact the municipal office to find out whether you need to submit your SWPPP for approval.
