Overview
TURNER 280 BORROW PIT is a stormwater outfall in Harpersville, Alabama, USA. It manages runoff from a borrow pit site near the intersection of US Highway 280 and AL 76.
TURNER 280 BORROW PIT is a stormwater outfall located in Harpersville, Shelby County, Alabama, United States. It serves a borrow pit operation, handling stormwater runoff from the site near the intersection of US Highway 280 and AL 76. The facility is operational and classified under NAICS codes 212390 (Other Nonmetallic Mineral Mining and Quarrying) and 212399 (All Other Nonmetallic Mineral Mining). As a stormwater outfall in Alabama, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permitting program administered by the Alabama Department of Environmental Management (ADEM). Stormwater discharges from industrial activities, including mining and quarrying, are regulated under the EPA's Multi-Sector General Permit (MSGP) for industrial stormwater. The facility must implement best management practices (BMPs) to control erosion, sedimentation, and pollutant runoff. The environmental significance of this outfall lies in its role in managing stormwater from a borrow pit, which can generate sediment-laden runoff. Proper management is essential to protect nearby water bodies from siltation and potential contamination. The facility's location in Shelby County, part of the Cahaba River watershed, underscores the importance of effective stormwater controls to maintain water quality in this ecologically sensitive area.
Environmental context
The TURNER 280 BORROW PIT outfall discharges stormwater from a borrow pit operation in the Cahaba River watershed, a region known for high aquatic biodiversity. Borrow pit activities can generate sediment and turbidity, which may impact downstream water quality if not properly managed. The facility is subject to NPDES industrial stormwater regulations requiring erosion and sediment control measures to minimize environmental impact.
Frequently asked questions
TURNER 280 BORROW PIT is located at the northwest corner of the intersection of US Highway 280 and AL 76 in Harpersville, Shelby County, Alabama, USA.
TURNER 280 BORROW PIT is a stormwater outfall that manages runoff from a borrow pit operation, classified under NAICS codes 212390 and 212399 for nonmetallic mineral mining and quarrying.
Stormwater discharges from borrow pits in Alabama are regulated under the EPA's Multi-Sector General Permit (MSGP) for industrial stormwater, administered by the Alabama Department of Environmental Management (ADEM). Facilities must implement best management practices to control erosion and sediment.
Borrow pit stormwater can carry high sediment loads, leading to turbidity and siltation in nearby streams. Proper erosion control and sediment basins are critical to protect water quality, especially in sensitive watersheds like the Cahaba River.
The NPDES MSGP is a national permit for industrial stormwater discharges. It requires facilities like TURNER 280 BORROW PIT to develop a Stormwater Pollution Prevention Plan (SWPPP), implement control measures, and conduct monitoring to minimize pollutant runoff.
