MCWANE CAST IRON PIPE CO. Stormwater Outfall, Birmingham, Alabama

MCWANE CAST IRON PIPE CO. is a stormwater outfall located at 3600 Richard Arrington Jr Boulevard North in Birmingham, Jefferson County, Alabama. This facility operates within the industrial sector, specifically under NAICS code 331511 (Iron Foundries), and is subject to stormwater discharge regulations under the Clean Water Act. As an industrial stormwater outfall, the facility is likely regulated under an NPDES Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The permit requires implementation of stormwater pollution prevention plans (SWPPPs) and monitoring of effluent limits for pollutants such as total suspended solids, oil and grease, and metals common in foundry operations. The outfall discharges to a receiving water body in the Birmingham area, which is part of the Black Warrior River watershed. Compliance with permit conditions is critical to protect local water quality, as industrial stormwater can carry pollutants from material storage, process areas, and vehicle traffic. The facility's location in an urban-industrial area underscores the importance of best management practices to minimize environmental impact.

The outfall is situated in Birmingham, Alabama, within the Black Warrior River basin. This region experiences a humid subtropical climate with frequent rainfall, increasing the potential for stormwater runoff to carry pollutants from industrial facilities. The local water bodies may be subject to impairments from sediment, metals, and other contaminants common in urban and industrial areas, making stormwater management critical for maintaining water quality standards.
