MSGP SPDES in Orange County

What does this measure?

The NYS Department of Environmental Conservation issues SPDES (State Pollutant Discharge Elimination System) permits to control the quality and character of wastewater and storm-water discharges in accordance with the Federal Clean Water Act. The SPDES Multi-Sector General Permit (MSGP) regulates stormwater discharges associated with industrial activity from a point source. The MSGP covers thirty one different industrial sectors which include activities such as mining, land transportation, and scrap recycling. This table covers data from 2020 through 2025.

Effective: Permit has been issued by the New York State Department of Environmental Conservation (NYSDEC) and is in force, legally authorizing a facility's wastewater or stormwater discharges.

No Exposure: All industrial materials and activities are completely protected from precipitation by a storm-resistant shelter. This exclusion allows facilities to be exempt from needing an NPDES (National Pollutant Discharge Elimination System) permit for stormwater, but it requires a certified declaration that all potential pollutants are covered and are not exposed to the elements, with submissions typically required every five years.
