ELFRETH JOHNSON ROAD PIT Stormwater Outfall, Birmingham, Alabama

ELFRETH JOHNSON ROAD PIT is a stormwater outfall located in Birmingham, Alabama, within Jefferson County. As a stormwater outfall, it manages runoff from urban and potentially industrial catchments, contributing to local flood control and water quality management. The facility is operational and falls under the regulatory framework of the US Clean Water Act, specifically the NPDES MS4 permit program, which governs stormwater discharges in urbanized areas. The facility's NAICS codes (212321 and 212399) suggest its catchment may include mining or related industrial activities, which can influence stormwater quality. In the context of Alabama's stormwater management, outfalls like this one are critical for conveying runoff to receiving waters while complying with permit limits for pollutants such as sediment, nutrients, and heavy metals. The regulatory framework requires monitoring and best management practices to minimize environmental impact. ELFRETH JOHNSON ROAD PIT plays a role in managing stormwater in the Birmingham metropolitan area, which experiences a humid subtropical climate with frequent rainfall. Effective stormwater management helps reduce flooding risks and protects local water bodies from pollution. The facility's location near industrial zones underscores the importance of compliance with discharge permits to safeguard downstream ecosystems.

The facility discharges stormwater from an area that includes industrial activities (mining-related NAICS codes), which can introduce pollutants like sediment, heavy metals, and hydrocarbons into local waterways. Birmingham's climate, with high annual rainfall, increases runoff volumes and the potential for erosion and pollutant transport. The receiving water bodies in the region may be impaired, requiring strict adherence to NPDES permit limits to protect aquatic life and downstream uses.
