APDES Permit

Our Municipal Separate Storm Sewer System (MS4) discharges stormwater into more than 30 waterways and wetlands within the Municipality of Anchorage (Municipality) and in State of Alaska rights-of-way owned or operated by the Alaska Department of Transportation and Public Facilities (DOT&PF). The National Pollutant Discharge Elimination System (NPDES) Program originated under section 402 of the Clean Water Act (CWA, 33 USC §1251), which requires that pollutant discharges to surface water be authorized by permit. Together, the Municipality and the DOT&PF are authorized to do so through an Authorization to Discharge under the National Pollutant Discharge Elimination System. This authorization, Alaska Pollutant Discharge Elimination System (APDES) Permit No. AKS 05255-8, is effective from August 1, 2015 to July 31, 2020. The Term III APDES permit required an update to the Quality Assurance Plan (QAP).

The APDES Permit also allows discharge of certain non-stormwater flows, as well as stormwater discharge associated with industrial activity and construction. It outlines compliance responsibilities, limitations, and the requirement of a Stormwater Management Program. The permit incorporates a schedule for compliance, and outlines strict monitoring, record keeping, and reporting requirements. Civil, administrative, and even criminal penalties can apply if the conditions of the permit are not met.
