Overview
SEWARD ROCK QUARRY is a stormwater outfall in Seward, Alaska, United States. It manages stormwater discharge from a quarry operation in the Kenai Peninsula.
SEWARD ROCK QUARRY is a stormwater outfall located at Mile 1.3 Dieckgraeff Road in Seward, Alaska, within the Kenai Peninsula County. The facility is operational and manages stormwater runoff from a quarry site, contributing to local drainage management in a region characterized by mountainous terrain and coastal climate. As a stormwater outfall in the United States, this facility operates under the Clean Water Act and is likely subject to National Pollutant Discharge Elimination System (NPDES) permit requirements, including those for industrial stormwater discharges. The Alaska Department of Environmental Conservation administers the NPDES program in the state, ensuring compliance with water quality standards for discharges into receiving waters. The facility's location in Seward, a coastal city on the Kenai Peninsula, means its stormwater discharges may affect local water bodies such as Resurrection Bay. Proper management of stormwater from quarry operations is important to prevent sediment and pollutant runoff, protecting aquatic habitats and downstream water quality in this ecologically sensitive area.
Environmental context
Seward, Alaska, is situated on the Kenai Peninsula with a subarctic climate and significant precipitation, leading to substantial stormwater runoff. The surrounding watershed includes Resurrection Bay, a marine ecosystem supporting salmon, marine mammals, and seabirds. Quarry operations can generate sediment-laden runoff, which if uncontrolled, may impair water quality and aquatic habitats. Regulatory oversight under the Clean Water Act aims to minimize such impacts through best management practices for erosion and sediment control.
