QUALITY SAND & GRAVEL, LLC Stormwater Outfall in Palmer, Alaska

QUALITY SAND & GRAVEL, LLC is a stormwater outfall facility located at 1500 South Tanya Court in Palmer, Alaska, within Matanuska-Susitna County. The facility is operational and manages stormwater runoff from industrial sand and gravel operations, a sector that typically requires compliance with the US EPA's National Pollutant Discharge Elimination System (NPDES) Multi-Sector General Permit (MSGP) for industrial activities. As a stormwater outfall, this facility discharges collected runoff into local waterways. In Alaska, stormwater management is regulated under the Clean Water Act, with permits often administered by the Alaska Department of Environmental Conservation (DEC) or the EPA. The facility's location in a cold climate with seasonal snowmelt presents unique challenges for stormwater control, including managing high flows during spring thaw and potential contaminants from industrial materials. The facility's environmental significance lies in its role in preventing pollution of nearby water bodies, such as the Matanuska River or Knik Arm. Proper stormwater management at sand and gravel operations is critical to minimize sediment runoff, which can impair aquatic habitats. The facility contributes to local flood control and water quality protection in the Palmer area.

Palmer, Alaska, is situated in the Matanuska-Susitna Valley, a region with a subarctic climate and significant seasonal snowmelt. Stormwater runoff from industrial sites like sand and gravel operations can carry sediment, heavy metals, and other pollutants into nearby streams and rivers, potentially affecting salmon habitats and water quality. The facility operates under the US EPA's NPDES permitting framework, which requires best management practices (BMPs) to control erosion and sedimentation.
