Overview
HILLIS DIRT PIT is a stormwater outfall located in Huntsville, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for managing urban stormwater runoff.
HILLIS DIRT PIT is a stormwater outfall facility situated at 500 JOEL DR in Huntsville, Madison County, Alabama, United States. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, which is part of the urbanized region of Huntsville. The facility is classified under NAICS code 212399 (Other Nonmetallic Mineral Mining and Quarrying), indicating its association with a former or active dirt pit that now functions in stormwater management. In the United States, stormwater outfalls like HILLIS DIRT PIT are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Huntsville, being a Phase II small MS4 community, is required to implement stormwater management programs to reduce pollutant discharges to the maximum extent practicable. The facility likely handles runoff from industrial or urban catchments, with typical management practices including sediment control and monitoring. The environmental significance of HILLIS DIRT PIT lies in its role in conveying stormwater to receiving waters, which may include local streams or the Tennessee River basin. Proper operation helps mitigate flooding and reduces the transport of pollutants such as sediment, nutrients, and heavy metals. The facility's location in a dirt pit suggests potential for high sediment loads, making erosion control a key operational focus.
Environmental context
The HILLIS DIRT PIT stormwater outfall is located in Huntsville, Alabama, within the Tennessee River watershed. The region experiences a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. Urban development in Huntsville increases impervious surfaces, elevating runoff volumes and pollutant loads. The outfall likely discharges to a water body that may be impaired by sediment or urban runoff, requiring compliance with Total Maximum Daily Load (TMDL) requirements under the Clean Water Act.
