Diversified Nonferrous Technologies Inc Stormwater Outfall, Birmingham, Alabama

Diversified Nonferrous Technologies Inc is an industrial stormwater outfall located at 2101 27th Ave N in Birmingham, Jefferson County, Alabama. The facility manages stormwater runoff from operations classified under NAICS codes 331529 (nonferrous metal foundries), 332919 (other metal valve and pipe fittings), and 332999 (miscellaneous fabricated metal products). As a stormwater outfall, it discharges collected runoff into local waterways, subject to the Clean Water Act and EPA's NPDES MS4 permit framework. The facility operates under Alabama's stormwater permitting program, which implements Phase II MS4 requirements for industrial sites. The outfall likely employs best management practices such as sediment basins, oil-water separators, or retention ponds to treat runoff before discharge. Given the industrial catchment, the stormwater may contain metals, oils, and suspended solids, requiring regular monitoring and compliance with effluent limits. Located in Birmingham's industrial corridor, this outfall contributes to managing urban stormwater quality in the Black Warrior River watershed. Proper operation helps reduce pollutant loads to receiving waters, supporting local water quality goals. The facility's compliance with NPDES permit conditions is critical for protecting downstream ecosystems and meeting Total Maximum Daily Load (TMDL) requirements.

The outfall discharges into the Black Warrior River basin, which supports diverse aquatic life and serves as a drinking water source. Birmingham's industrial history has led to legacy sediment and metal contamination in local waterways. The facility's catchment includes metal fabrication operations, posing risks of heavy metal and hydrocarbon runoff. Effective stormwater management is essential to prevent impairment of receiving waters and to comply with Alabama's water quality standards.
