Is your facility required to be covered under a State Pollutant Discharge Elimination System (SPDES) multi-sector general permit (MSGP)?

If your facility’s operations fall into one or more categories listed in 40 CFR 122.26(b)(14)(i-ix) and (xi) you will need to evaluate:

  • Your location
  • Approximate distance
  • Prevailing gradient flow in relation to the nearest surface water body or municipal separate storm sewer system (MS4).

You may not be required to file an application for MSGP or not be eligible for coverage under MSGP if:

  • Neither a surface water body, nor MS4s are located within a potential reach for your Stormwater discharge.
  • Facilities activities are not listed in the the 40CFR 122.26(b)(14)(i-ix) and (xi).

** If you are not eligible for the MSGP coverage, you may still need to seek coverage under an individual or a special SPDES permit.

** If you are eligible for an MSGP, you will need to have a Notice of Intent (NOI) filed with NYSDEC and a Stormwater Pollution Prevention Plan (SWPPP) prepared for your facility by a qualified professional.

What to do after your SPDES permit is issued:

  • Conduct regular inspections.
  • Monitoring and sampling.
  • Submit reports through and Net DMR websites.

If you are not eligible for a MSGP, but do need a SPDES permit, an individual application needs to be filed by a qualified professional.
