AVERY BORROW PIT Stormwater Outfall, Hamilton, Alabama | United States

AVERY BORROW PIT is a stormwater outfall facility located at 100 Arrow Dr, Hamilton, Alabama, in Marion County. As a stormwater outfall, it manages runoff from the surrounding area, which includes industrial activities associated with NAICS codes 212390 and 212399 (other nonmetallic mineral mining and quarrying). The facility is operational and plays a role in local stormwater management. In the United States, stormwater outfalls are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Hamilton, as a small municipality, likely falls under Phase II MS4 requirements, which mandate stormwater management programs to reduce pollutant discharges to the maximum extent practicable. The facility's industrial catchment suggests potential for sediment and other pollutants common to mining operations. The environmental significance of AVERY BORROW PIT lies in its contribution to managing stormwater runoff from industrial and urban areas in Hamilton. Proper operation helps protect local water bodies from erosion, sedimentation, and pollutant loading. The facility supports community resilience by mitigating flood risks and maintaining water quality in the region.

Hamilton, Alabama, experiences a humid subtropical climate with significant rainfall, making stormwater management critical for flood control and water quality. The facility's catchment includes industrial mining activities, which can contribute sediment and other pollutants to runoff. Discharge from this outfall likely enters local streams or rivers, potentially affecting downstream water bodies. Regulatory oversight under the NPDES MS4 program aims to minimize these impacts through best management practices.
