Overview
PURINTON PRODUCTS- WEST SUSITNA PIT is a stormwater outfall in Big Lake, Alaska, United States. It manages stormwater discharge from an industrial site under the US EPA NPDES MS4 permit framework.
PURINTON PRODUCTS- WEST SUSITNA PIT is a stormwater outfall located at 21252 West Susitna Parkway in Big Lake, Alaska, within the Yukon-Koyukuk Census Area. This facility handles stormwater runoff from an industrial or commercial site, operating under the regulatory oversight of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. As a stormwater outfall, it serves as a discharge point for collected stormwater, which may carry pollutants from the catchment area. The facility operates in a region characterized by a subarctic climate with significant seasonal variations in precipitation and snowmelt. Stormwater management in Alaska must account for permafrost conditions and short construction seasons. The outfall likely incorporates best management practices (BMPs) such as sediment basins or vegetated swales to control erosion and filter pollutants before discharge. Regulatory compliance under the Clean Water Act requires monitoring of discharge quality and implementation of stormwater pollution prevention plans (SWPPPs). This outfall contributes to local flood control and water quality protection in the Big Lake area. Its location near residential and natural areas underscores the importance of effective stormwater treatment to prevent contamination of receiving waters. The facility's operational status indicates ongoing management of stormwater runoff, supporting community and environmental health in the region.
Environmental context
The facility discharges stormwater in a region with sensitive aquatic ecosystems, including salmon-bearing streams and wetlands. Urban and industrial runoff can introduce sediments, heavy metals, and hydrocarbons, posing risks to water quality. The Clean Water Act and Alaska's water quality standards regulate discharges to protect beneficial uses such as fishing and recreation. Effective stormwater management is critical to minimize impacts on these valuable resources.
