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.

Highlights of Permit Reissuance (2015 MSGP) - NEW

On February 19, 2015 DEC issued the 2015 Multi-Sector General Permit for Storm Water Discharges Associated with Industrial Activity (2015 MSGP, AKR060000).

Permit documents can be accessed from the ADEC Wastewater Discharge Authorization Program website in the Recently Issued Permits section.

The permit becomes 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.

Expiration of the 2008 MSGP

The 2008 MSGP expired at midnight on September 29, 2013. 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 (2015 MSGP) is in effect. Permittees already covered under the 2008 MSGP are not required to submit a new Notice of Intent (NOI) for permit coverage until the 2015 MSGP is in effect. 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.

With the recent issuance of the 2015 MSGP, existing dischargers or new dischargers seeking authorization should submit a new Notice of Intent (NOI) and Storm Water Pollution Prevention Plan (SWPPP) no later than 120 days after the effective date of the 2015 MSGP permit. See Table 2-1 in the 2015 MSGP Permit for NOI Submission deadlines and discharge Authorization Dates.

If you are expecting to find an ADEC NOI on the Water Permit Search and it is not displaying, please send your inquiry to DEC.Water.OPAHelp@Alaska.Gov

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.
