Overview
GSC Borrow Pit is a stormwater outfall in Calera, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for stormwater discharge management.
GSC Borrow Pit is a stormwater outfall located at 757 CO RD 87 in Calera, Shelby County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff in the area. As a stormwater outfall, it is part of the broader infrastructure managed under the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits, which regulate stormwater discharges from municipal and industrial sources. The facility's NAICS code (212399) indicates it is associated with nonmetallic mineral mining and quarrying, suggesting the outfall may serve an industrial catchment related to mining activities. Stormwater outfalls in such contexts are designed to convey runoff from impervious surfaces and industrial areas, with potential pollutants including sediment, heavy metals, and hydrocarbons. The regulatory framework under the Clean Water Act requires permits that include best management practices (BMPs) to control pollution. Located in Calera, Alabama, the outfall discharges into local water bodies that may eventually reach the Cahaba River or other regional watersheds. The facility's role is to manage stormwater volume and quality, mitigating flood risks and protecting downstream ecosystems. Compliance with NPDES permit conditions is critical to minimize environmental impact from urban and industrial runoff in this growing suburban area.
Environmental context
The GSC Borrow Pit outfall is situated in Shelby County, Alabama, an area experiencing suburban growth near Birmingham. Stormwater runoff from industrial and developing areas can carry sediment, nutrients, and pollutants into local streams and rivers, potentially affecting water quality in the Cahaba River watershed, which is known for its biodiversity. Regulatory oversight under the EPA's NPDES MS4 program requires permits to control discharges through structural and non-structural BMPs, aiming to protect aquatic habitats and drinking water sources.
