Overview
Delta Western Petroleum, Inc. operates a stormwater outfall in Juneau, Alaska, managing runoff from an industrial facility. The outfall discharges into local waters under EPA NPDES MS4 permit requirements.
Delta Western Petroleum, Inc. manages a stormwater outfall located at 120 Mt. Roberts Street in Juneau, Alaska, within the Juneau City and Borough. This facility handles stormwater runoff from an industrial petroleum storage and distribution site, contributing to local stormwater management in a region with significant precipitation. The facility operates under the U.S. EPA's National Pollutant Discharge Elimination System (NPDES) framework, which governs stormwater discharges from industrial activities. As an industrial stormwater outfall, it is subject to Multi-Sector General Permit (MSGP) requirements, including pollution prevention plans and monitoring for pollutants such as oil and grease, metals, and sediments. The site's location in a coastal urban area with steep terrain influences runoff characteristics. Stormwater management at this facility is critical for protecting nearby water bodies, including Gastineau Channel and the surrounding marine ecosystem. Effective control of runoff from the petroleum facility helps prevent contamination from hydrocarbons and other industrial pollutants, supporting water quality in a region valued for its fisheries and natural environment.
Environmental context
Juneau's coastal rainforest climate produces high annual precipitation, leading to substantial stormwater runoff. The facility's industrial activities involve petroleum storage, posing risks of hydrocarbon spills and contaminated runoff. Discharge from the outfall enters waters that may be sensitive to pollutants, given the area's ecological importance for salmon and other marine life. Regulatory oversight under the Clean Water Act aims to minimize impacts through best management practices and monitoring.
Frequently asked questions
The stormwater outfall is located at 120 Mt. Roberts Street in Juneau, Alaska, within the Juneau City and Borough.
It manages stormwater runoff from an industrial petroleum facility, discharging treated or untreated runoff into local waters under an EPA NPDES permit.
The outfall is regulated under the Clean Water Act's NPDES program, specifically the Multi-Sector General Permit for industrial stormwater discharges, which requires pollution prevention and monitoring.
Alaska's stormwater management follows EPA NPDES MS4 permits, but unique challenges include cold climate operations, permafrost, and remote locations. The state has delegated authority for some NPDES permits.
Common pollutants include oil and grease, total suspended solids, metals (e.g., zinc, copper), and pH. Monitoring frequency depends on the permit and facility risk level.
