Overview
CHUGIAK AGGREGATE FACILITY is an operational stormwater outfall in Chugiak, Alaska, United States. It manages stormwater runoff from an aggregate facility under the US EPA NPDES MS4 permit framework.
CHUGIAK AGGREGATE FACILITY is a stormwater outfall located at 19111 Old Glenn Highway in Chugiak, Alaska, within Anchorage County. As an operational facility in the United States, it falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits, which govern stormwater discharges from industrial and municipal sources. The facility manages stormwater runoff from an aggregate processing and storage site, a common industrial sector in Alaska. Typical stormwater management at aggregate facilities includes sediment basins, detention ponds, and erosion control measures to comply with Clean Water Act requirements. Located in the Chugiak area near the Knik Arm of Cook Inlet, the facility's stormwater discharges may affect local water quality. The site operates under Alaska's water quality standards and EPA Region 10 oversight. Proper stormwater management is critical in this region due to sensitive aquatic habitats and the potential for sediment-laden runoff from industrial operations.
Environmental context
The facility is situated in the Chugiak area of Alaska, a region with a subarctic climate and significant seasonal snowmelt. Stormwater runoff from aggregate facilities can carry high sediment loads, potentially impacting nearby water bodies such as the Knik River or Cook Inlet. The site operates under the Clean Water Act and Alaska's water quality standards, requiring best management practices for erosion and sediment control to protect aquatic habitats.
Frequently asked questions
CHUGIAK AGGREGATE FACILITY is located at 19111 Old Glenn Highway in Chugiak, Alaska, within Anchorage County, United States.
It is a stormwater outfall that manages runoff from an aggregate facility, discharging stormwater in compliance with the Clean Water Act and NPDES MS4 permits.
Stormwater outfalls in Alaska are regulated under the US EPA's NPDES MS4 program, which requires permits for discharges from industrial and municipal sources to protect water quality.
The facility likely uses best management practices such as sediment basins, detention ponds, and erosion controls to treat runoff before discharge, as required by its NPDES permit.
Aggregate facility stormwater can contain high sediment loads, which may harm aquatic habitats. Proper management is essential to prevent erosion and protect downstream water bodies like Cook Inlet.
