Hamilton Street and Sanitation Department Stormwater Outfall, Hamilton, Alabama

The Hamilton Street and Sanitation Department operates a stormwater outfall located at 456 Bexar Ave E in Hamilton, Alabama, within Marion County. This facility is part of the municipal separate storm sewer system (MS4) that collects and discharges stormwater runoff from urban areas to protect local water quality. As a stormwater outfall, this facility is regulated under the US Clean Water Act and likely operates under an NPDES MS4 permit. The City of Hamilton, as a small municipality, would be subject to Phase II MS4 requirements, which mandate stormwater management programs to reduce pollutant discharges to the maximum extent practicable. Typical controls include public education, illicit discharge detection, construction site runoff control, and post-construction stormwater management. The outfall serves the Hamilton urban area, discharging stormwater into receiving waters that may include tributaries of the Tombigbee River. Proper operation helps mitigate flooding, erosion, and pollutant loading from urban surfaces. The facility's role is critical for maintaining compliance with water quality standards in Alabama's streams and rivers.

Hamilton is located in the Black Belt region of Alabama, characterized by clay soils and rolling hills. Stormwater runoff from urban areas can carry sediment, nutrients, heavy metals, and pathogens into local waterways. The receiving waters likely drain to the Tombigbee River basin, which supports diverse aquatic life and is used for recreation and drinking water downstream. Effective stormwater management is essential to prevent impairment of these water bodies from urban runoff.
