VALLEY MACHINE COMPANY, INC. Stormwater Outfall, Alexandria, Alabama

VALLEY MACHINE COMPANY, INC. is an industrial stormwater outfall located at 100 VMC Dr in Alexandria, Calhoun County, Alabama, United States. The facility manages stormwater discharge from metal fabrication operations (NAICS 332312 and 332999) and is classified as a stormwater outfall under the National Pollutant Discharge Elimination System (NPDES). As an operational industrial facility, it is subject to EPA's Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The facility operates under the regulatory framework of the Clean Water Act, specifically the NPDES stormwater program. Industrial stormwater outfalls like this one are required to implement Stormwater Pollution Prevention Plans (SWPPPs) and conduct regular monitoring to ensure compliance with effluent limits. The site's location in Calhoun County places it within the Coosa River watershed, a region with significant industrial and agricultural activity. Environmental significance stems from the potential for industrial runoff to carry pollutants such as metals, oils, and sediments into local waterways. Proper management of this outfall helps protect water quality in the Coosa River basin, which supports diverse aquatic ecosystems and provides drinking water for downstream communities. The facility's compliance with NPDES requirements is critical for minimizing environmental impact.

The facility discharges into the Coosa River watershed, a major tributary of the Alabama River system. This region experiences a humid subtropical climate with heavy rainfall, increasing the risk of stormwater runoff carrying industrial pollutants. The watershed supports diverse aquatic life and is used for recreation and drinking water. Regulatory oversight under the Clean Water Act ensures that industrial stormwater discharges are managed to protect these resources.
