Overview
WHITEHALL CHERT PIT is a stormwater outfall in Valley Head, Alabama, serving an industrial catchment associated with mining activities. It operates under US EPA NPDES MS4 regulations.
WHITEHALL CHERT PIT is a stormwater outfall located at the end of Whitehall Lane in Valley Head, DeKalb County, Alabama, United States. This facility manages stormwater runoff from an industrial catchment, likely associated with mining operations given the NAICS codes 212390 and 212399 (other nonmetallic mineral mining and quarrying). As a stormwater outfall, it discharges collected runoff into local waterways, playing a key role in managing water quality in the area. The facility operates under the regulatory framework of the US Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. As an industrial stormwater outfall, it may be subject to additional sector-specific requirements under the EPA's Industrial Stormwater Program. The operational status is active, indicating ongoing management of stormwater discharges to comply with permit conditions and protect receiving waters. Located in the Appalachian foothills of northeastern Alabama, the outfall discharges into a region characterized by karst topography and sensitive aquatic ecosystems. Proper stormwater management is critical to prevent sediment, nutrients, and potential mining-related pollutants from degrading water quality in downstream rivers and streams. The facility's role in controlling runoff from industrial activities supports local environmental health and regulatory compliance.
Environmental context
The facility is situated in DeKalb County, Alabama, within the Coosa River basin, which features karst geology and numerous springs. Stormwater runoff from industrial mining operations can carry sediment and metals, posing risks to aquatic habitats. Effective management through this outfall helps mitigate impacts on local water bodies, which support diverse fish and macroinvertebrate communities.
