The goal of the Storm Water Program is to reduce or eliminate pollutants in storm water. Storm water discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops, during rainfall and snowmelt events. Storm water discharges often contain pollutants in quantities that could adversely affect water quality.
Highlights of Permit Reissuance of Construction General Permit (2016 CGP)
On December 29, 2015 DEC reissued the Construction General Permit for Storm Water Discharges for Large and Small Construction Activities (2016 CGP, AKR100000).
The 2016 CGP became effective on February 1, 2016.
The 2016 CGP authorizes storm water discharges from large and small construction-related activities that result in a total land disturbance of equal to or greater than one acre and where those discharges enter waters of the U.S. (directly or through a storm water conveyance system) or a municipal separate storm sewer system (MS4) leading to waters of the U.S. subject to the conditions set forth in the permit. The permit also authorizes storm water discharges from certain construction support activities and some non-storm water discharges commonly associated with construction sites.
The goal of the 2016 CGP is to minimize erosion and reduce or eliminate the discharge of pollutants, such as sediment carried in storm water runoff from construction sites through implementation of appropriate control measures. Polluted storm water runoff can adversely affect fish, animals, plants, and humans. In order to ensure protection of water quality and human health, the permit describes control measures that must be used to manage storm water runoff during construction activities.
Highlights of Permit Reissuance (2015 MSGP)
On February 19, 2015 DEC issued the 2015 Multi-Sector General Permit for Storm Water Discharges Associated with Industrial Activity (2015 MSGP, AKR060000).
The permit became effective on April 1, 2015.
Existing dischargers of the 2008 MSGP or new dischargers seeking authorization should submit a new Notice of Intent (2015 MSGP NOI) and Storm Water Pollution Prevention Plan (SWPPP) no later than 120 days after the effective date of the permit (April 1 - July 30, 2015).
See Table 2-1 in the 2015 MSGP Permit for NOI Submission deadlines and discharge Authorization Dates. DEC will begin accepting 2015 MSGP NOI's on April 1, 2015.
