Overview
SKOOKUM QUARRY is a stormwater outfall in Chugiak, Alaska, serving the Anchorage Municipality. It operates under US EPA NPDES MS4 regulations for stormwater discharge from quarry operations.
SKOOKUM QUARRY is a stormwater outfall located at 17633 Old Glenn Highway in Chugiak, Alaska, within the Anchorage Municipality. The facility is operational and classified under NAICS codes 212312 and 212319, indicating crushed and broken stone mining and quarrying activities. As a stormwater outfall, it manages runoff from quarry operations, which can include sediment and other pollutants. In the United States, stormwater outfalls like SKOOKUM QUARRY are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Phase I and Phase II MS4 permits require facilities to implement stormwater management plans to control pollution. For quarry operations, typical best management practices include sediment basins, silt fences, and erosion control measures to minimize discharge impacts. The environmental significance of SKOOKUM QUARRY lies in its role in managing stormwater runoff from industrial quarrying activities in the Chugiak area. Proper stormwater management is critical to protect local water bodies, such as the nearby Knik Arm and tributaries, from sedimentation and potential contaminants. The facility's compliance with NPDES permits ensures that discharge meets water quality standards, supporting the ecological health of the region.
