D & S CONCRETE INC Stormwater Outfall, Anchorage, Alaska | United States

D & S CONCRETE INC is a stormwater outfall located at 2140 E. 84th Ct. in Anchorage, Alaska. The facility operates under the jurisdiction of the Anchorage Municipality and is classified as a stormwater outfall, managing runoff from an industrial concrete production site. As a stormwater outfall in the United States, this facility is subject to the Clean Water Act and likely operates under an NPDES MS4 permit, given its location in an urbanized area. The facility's discharge may be regulated under Phase II MS4 requirements for small municipalities, as Anchorage is a significant urban center. Stormwater outfalls in industrial settings like concrete manufacturing must comply with effluent guidelines and stormwater pollution prevention plans (SWPPP) to control pollutants such as sediment, pH, and heavy metals. The environmental significance of this outfall lies in its potential impact on local water bodies. Anchorage's stormwater system drains into Cook Inlet, a sensitive estuarine environment. Proper management of stormwater from industrial sites is critical to prevent contamination and protect aquatic habitats. The facility's operational status indicates ongoing compliance with regulatory requirements.

Anchorage, Alaska, experiences a subarctic climate with significant seasonal snowmelt, which can affect stormwater runoff volumes and pollutant loads. The facility's discharge enters the Cook Inlet watershed, an ecologically important estuary supporting salmon, marine mammals, and migratory birds. Industrial stormwater from concrete manufacturing may contain elevated pH, total suspended solids, and trace metals, necessitating robust treatment and monitoring to meet water quality standards.
