Overview
TRIDENT BASIN QUARRY is a stormwater outfall in Kodiak, Alaska, United States. It serves an industrial quarry catchment and operates under US EPA NPDES MS4 regulations.
TRIDENT BASIN QUARRY is a stormwater outfall located at 100-220 Trident Way in Kodiak, Alaska, within Kodiak Island County. This facility manages stormwater runoff from an industrial quarry operation, classified under NAICS 212321 (Construction Sand and Gravel Mining). As a stormwater outfall, it discharges collected runoff into the local watershed, playing a key role in managing water quality from the quarry site. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. As an industrial stormwater discharge, it is subject to EPA's Multi-Sector General Permit (MSGP) for industrial activities, which requires stormwater pollution prevention plans and monitoring. The quarry's stormwater management likely includes sediment basins and erosion control measures to mitigate impacts from mining operations. Located in Kodiak, Alaska, the outfall discharges into a region characterized by coastal temperate rainforest and sensitive aquatic ecosystems. The facility's stormwater management is critical to preventing sediment and pollutant runoff from the quarry into nearby water bodies, supporting local water quality and habitat protection. Its operational status ensures ongoing compliance with federal stormwater regulations.
Environmental context
The Kodiak Island region features a coastal temperate rainforest climate with high precipitation, making stormwater management crucial for preventing erosion and sediment transport. The quarry's industrial catchment may generate runoff containing suspended solids and potential pollutants, requiring effective treatment to protect downstream aquatic habitats. Discharge from the outfall likely enters a water body that supports salmon and other sensitive species, underscoring the need for robust stormwater controls.
Frequently asked questions
TRIDENT BASIN QUARRY is located at 100-220 Trident Way in Kodiak, Alaska, within Kodiak Island County, United States.
TRIDENT BASIN QUARRY is a stormwater outfall that manages runoff from an industrial quarry operation, classified under NAICS 212321 (Construction Sand and Gravel Mining).
Stormwater outfalls in Alaska are regulated under the US Clean Water Act through the NPDES program. Industrial facilities like quarries must obtain coverage under the Multi-Sector General Permit (MSGP), which requires stormwater pollution prevention plans and monitoring.
As an industrial stormwater outfall, TRIDENT BASIN QUARRY likely employs best management practices such as sediment basins, erosion controls, and regular monitoring to comply with NPDES permit requirements and minimize environmental impact.
Effective stormwater management at quarries prevents sediment and pollutant runoff into nearby water bodies, protecting aquatic habitats and water quality. In regions like Kodiak with high rainfall and sensitive ecosystems, this is critical for sustaining local fisheries and biodiversity.
