SEWARD ROCK QUARRY 2 Stormwater Outfall, Seward, Alaska | United States

SEWARD ROCK QUARRY 2 is a stormwater outfall facility located in Seward, Alaska, within the Kenai Peninsula County. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, likely including the quarry and nearby urban or industrial surfaces. The facility is operational and plays a role in managing local stormwater to prevent flooding and control pollutant loads. In the United States, stormwater outfalls are regulated under the Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Depending on the municipality's size, Seward may be subject to Phase II MS4 requirements, which mandate stormwater management programs to reduce pollutant discharges to the maximum extent practicable. The facility's location in Alaska presents unique challenges due to cold climates, including snowmelt and frozen ground conditions that affect runoff patterns. The environmental significance of this outfall lies in its potential discharge to nearby water bodies, such as Resurrection Bay or other streams in the Kenai Peninsula. Stormwater runoff can carry pollutants like sediment, oil, and heavy metals from urban and industrial areas. Proper management of this outfall helps protect local water quality and aquatic habitats, supporting the region's fisheries and recreational uses.

Seward is located on the Kenai Peninsula, a region known for its pristine coastal ecosystems and salmon-bearing streams. Stormwater runoff from urban and industrial areas, including the rock quarry, can introduce sediment, nutrients, and contaminants into nearby water bodies. The facility's discharge may affect Resurrection Bay, which supports diverse marine life and commercial fishing. Managing stormwater quality is critical to preserving these ecological resources and meeting state water quality standards under the Clean Water Act.
