Overview
Stabler Point Rock Quarry is an operational stormwater outfall in Juneau, Alaska, serving a quarrying operation. It manages runoff from industrial activities under US EPA NPDES MS4 regulations.
Stabler Point Rock Quarry is a stormwater outfall located at Mile 13 Veteran's Memorial Highway in Juneau, Alaska, within the Juneau City and Borough. This facility manages stormwater runoff from quarrying operations, including NAICS codes 212312 (Crushed and Broken Limestone Mining), 212313 (Crushed and Broken Granite Mining), and 212319 (Other Crushed and Broken Stone Mining). As an industrial stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, specifically under the Multi-Sector General Permit (MSGP) for industrial activities. The facility operates in the coastal temperate rainforest of Southeast Alaska, where high annual precipitation (over 90 inches) generates significant stormwater runoff. The outfall likely discharges to nearby water bodies, potentially including Gastineau Channel or tributaries of the Mendenhall River. Regulatory oversight includes compliance with Alaska Department of Environmental Conservation (ADEC) water quality standards and the Clean Water Act. Typical stormwater management at quarry sites involves sediment basins, silt fences, and erosion control measures to mitigate impacts from exposed surfaces and heavy equipment. Environmental significance centers on protecting sensitive aquatic habitats in the region, including salmon-bearing streams and marine ecosystems. The quarry's stormwater outfall must control sediment loads and potential contaminants like heavy metals from rock crushing. Effective management supports local water quality and the broader ecological health of the Juneau area, which relies on clean water for fisheries, recreation, and community water supplies.
Environmental context
Juneau's coastal temperate rainforest climate produces heavy rainfall, leading to substantial stormwater runoff from industrial sites like Stabler Point Rock Quarry. The outfall discharges to waters that may support salmonids and other aquatic life, requiring strict sediment and pollutant control. Regulatory compliance under the Clean Water Act and Alaska's water quality standards is critical to prevent degradation of these sensitive ecosystems.
