Storm Water

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.

Expiration of the 2008 MSGP

The 2008 MSGP expired at midnight on September 29, 2013. A new permit to replace it has not been issued. Permittees who obtained coverage under the 2008 MSGP prior to its expiration are automatically granted an administrative continuance of permit coverage. The administrative continuance will remain in effect until a new permit is issued. Permittees already covered under the 2008 MSGP are not required to submit a new Notice of Intent (NOI) for permit coverage until the MSGP is reissued. Permittees must continue to comply with all requirements in the 2008 permit, including requirements for monitoring and reporting.

New facilities seeking to discharge stormwater associated with industrial activity are unable to apply for permit coverage until DEC reissues the MSGP to replace the administratively extended 2008 MSGP. DEC issued a “no action assurance” memorandum for newly-discharging facilities. The memo states that the Department will not pursue administrative or civil judicial enforcement actions for lack of permit coverage against a newly-discharging facility, provided that the operator meets the requirements established in the memorandum attached memo (PDF, 2 pp, 408K).

Per the No Action Assurance Memo, new operators are to submit an NOI using the paper form. Additional MSGP forms are located at Storm Water Forms webpage.

At this time DEC expects to reissue the MSGP in the fall of 2014 or early 2015. At that time all operators desiring coverage under the MSGP, including those with administrative continuance under the 2008 MSGP, will need to submit NOIs for permit coverage.

New to the eNOI System is the CGP eNOI Modification submittal. This submittal allows operators to electronically file the CGP Notice of Intent Modification form. For additional information, see the "Step-by-Step" guidance document.
