West Glacier Development, LLC Stormwater Outfall, Juneau, Alaska

West Glacier Development, LLC is a stormwater outfall facility located at 5580 Montana Creek Road in Juneau, Alaska, within the Juneau City and Borough. The facility is operational and serves the industrial sector, specifically classified under NAICS code 212321 (Construction Sand and Gravel Mining). As a stormwater outfall, it manages surface runoff from the site to prevent flooding and control pollutant discharge. The facility operates under the regulatory framework of the US Clean Water Act, which governs stormwater discharges through the National Pollutant Discharge Elimination System (NPDES). In Alaska, stormwater permits are administered by the Alaska Department of Environmental Conservation or the US EPA, depending on the jurisdiction. The site's industrial classification requires compliance with sector-specific stormwater management practices, including erosion control and sediment management. Located in Juneau, a coastal city in Southeast Alaska, the facility's stormwater management is critical for protecting local water bodies, including nearby Montana Creek and the Gastineau Channel. Proper operation helps mitigate impacts from sediment and potential contaminants associated with mining activities, supporting water quality and aquatic habitat in the region.

Juneau's coastal rainforest climate, with high annual precipitation, creates significant stormwater runoff volumes. The facility's discharge may affect Montana Creek, a salmon-bearing stream, and ultimately the Gastineau Channel. Industrial activities like sand and gravel mining can increase sediment loads and introduce pollutants, making effective stormwater management essential for protecting aquatic ecosystems and complying with Clean Water Act standards.
