HYPONEX CORPORATION Stormwater Outfall, Vance, Alabama | Industrial Runoff Management

HYPONEX CORPORATION operates a stormwater outfall located at 10638 MOUNT MORIAH ROAD in Vance, Tuscaloosa County, Alabama. This facility manages stormwater runoff from industrial operations, classified under NAICS codes 238910 (Site Preparation Contractors) and 325314 (Fertilizer Manufacturing). As a stormwater outfall, it discharges collected runoff into local waterways, subject to regulatory oversight. The facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) MS4 permit framework, which governs stormwater discharges from industrial and municipal sources. Alabama's stormwater program is administered by the Alabama Department of Environmental Management (ADEM), requiring permits for industrial stormwater discharges to protect water quality. The outfall likely serves an industrial catchment area, with runoff potentially containing sediments, nutrients, or other pollutants typical of construction and manufacturing sites. Environmental significance lies in its discharge to receiving waters in the Black Warrior River basin, which supports aquatic ecosystems and downstream water uses. Proper management of stormwater runoff is critical to prevent erosion, flooding, and pollution. The facility's compliance with NPDES permit conditions helps mitigate impacts on local water quality and aligns with Clean Water Act goals.

The facility discharges stormwater into the Black Warrior River watershed, a region characterized by mixed urban and industrial land use. Runoff from industrial sites can carry pollutants such as sediments, heavy metals, and chemicals, posing risks to aquatic habitats. Alabama's stormwater regulations require best management practices (BMPs) to control runoff quality and quantity, particularly for facilities with high pollutant potential.
