Overview
Thomasville Pit is a stormwater outfall in Thomasville, Alabama, serving the local drainage network. It operates under US EPA NPDES MS4 regulations for stormwater management.
Thomasville Pit is a stormwater outfall located at CR 27 at North City Limits in Thomasville, Clarke County, Alabama. As a stormwater outfall, it discharges collected stormwater runoff from the surrounding area into a receiving water body. The facility is operational and plays a role in managing urban stormwater in this small city. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. As a stormwater outfall in a small municipality, it likely falls under Phase II MS4 requirements, which mandate stormwater management plans to reduce pollutant discharges to the maximum extent practicable. The associated NAICS codes (212321 and 212325) indicate industrial activity related to construction sand and gravel mining, suggesting the outfall may serve an industrial catchment area. Thomasville Pit contributes to local flood control and water quality management by conveying stormwater runoff. Its location near the city limits and potential industrial catchment means it must comply with permit conditions to protect downstream water bodies. Effective stormwater management at this outfall helps reduce erosion, flooding, and pollutant loading in the local watershed.
Environmental context
The outfall is located in Clarke County, Alabama, within the Tombigbee River watershed. The region experiences a humid subtropical climate with frequent heavy rainfall, making stormwater management critical for flood prevention and water quality. The nearby industrial activities (sand and gravel mining) can contribute sediment and other pollutants to runoff, necessitating proper erosion and sediment controls. Discharge from the outfall may affect local streams and the Tombigbee River, which are important for aquatic habitat and downstream water supply.
Frequently asked questions
Thomasville Pit is located at CR 27 at North City Limits in Thomasville, Clarke County, Alabama, United States.
Thomasville Pit is a stormwater outfall that discharges collected stormwater runoff from the surrounding area, including potential industrial catchments, into a receiving water body.
Thomasville Pit operates under the US Clean Water Act's NPDES MS4 program, likely Phase II for small municipalities, requiring stormwater management plans to reduce pollutant discharges.
Stormwater outfalls convey runoff from urban and industrial areas to water bodies, impacting water quality and flood control. Proper management reduces pollution, erosion, and flooding risks.
Industrial activities like sand and gravel mining can increase sediment and pollutant loads in runoff. Stormwater outfalls serving such areas must implement controls to meet permit limits and protect water quality.
