A & A Machine and Welding Stormwater Outfall, Jasper, Alabama | Industrial Runoff Management

A & A Machine and Welding is an industrial facility located at 135 Reed Road in Jasper, Alabama, within Walker County. The site operates a stormwater outfall that discharges runoff from its manufacturing operations, which include NAICS codes 332710 (Machine Shops) and 332999 (All Other Miscellaneous Fabricated Metal Product Manufacturing). As a stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, specifically under the Multi-Sector General Permit (MSGP) for industrial activities. Under the Clean Water Act, industrial stormwater discharges must be managed to minimize pollution through best management practices (BMPs) and, where required, numeric effluent limitations. The facility's outfall likely conveys runoff from impervious surfaces, loading areas, and material storage zones. Typical controls include sediment basins, oil-water separators, and spill prevention measures. Compliance is monitored through periodic inspections and sampling. The environmental significance of this outfall lies in its potential impact on local waterways in the Black Warrior River watershed. Stormwater from industrial sites can carry heavy metals, oils, and sediments if not properly treated. The facility's location in a mixed urban-industrial area of Jasper underscores the importance of effective stormwater management to protect downstream water quality and aquatic habitats.

The outfall discharges into the Black Warrior River basin, which supports diverse aquatic life and provides drinking water for communities in central Alabama. Industrial stormwater runoff from metal fabrication facilities may contain pollutants such as zinc, copper, and total suspended solids. The facility's proximity to residential areas and local streams heightens the need for robust stormwater controls to prevent contamination and comply with Alabama's water quality standards.
