FENNY DIRT PIT #2 Stormwater Outfall, Huntsville, Alabama | United States

FENNY DIRT PIT #2 is a stormwater outfall located in Huntsville, Alabama, within Madison County. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, likely including industrial or urban catchments. The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which governs stormwater discharges in the United States. The facility's NAICS code (212399) indicates it may be associated with nonmetallic mineral mining and quarrying activities, suggesting the outfall handles runoff from an industrial site. Stormwater outfalls in such contexts are designed to convey runoff to receiving waters while managing pollutants. The regulatory framework requires permits that include stormwater pollution prevention plans (SWPPPs) and monitoring to ensure compliance with water quality standards. Located in Huntsville, a growing city in northern Alabama, the outfall contributes to local stormwater management infrastructure. Proper operation helps protect downstream water bodies from pollution, supporting community and environmental health. The facility's role is part of broader efforts to manage urban runoff and mitigate flooding and water quality impacts in the Tennessee Valley region.

The outfall discharges stormwater from an area with potential industrial activity (NAICS 212399), which may contribute pollutants such as sediment, heavy metals, or hydrocarbons to receiving waters. Huntsville's climate features frequent rainfall, increasing runoff volumes. The facility operates under MS4 permit requirements that mandate best management practices (BMPs) to control pollution.
