Overview
MT. MILLS CHERT PIT is a stormwater outfall in Tuscumbia, Alabama, USA. It manages runoff from mining operations under NPDES MS4 permit requirements.
MT. MILLS CHERT PIT is a stormwater outfall located in Tuscumbia, Colbert County, Alabama, United States. The facility is operational and serves as a discharge point for stormwater runoff from mining activities, classified under NAICS codes 212321 (Construction Sand and Gravel Mining) and 212399 (Other Nonmetallic Mineral Mining and Quarrying). As a stormwater outfall, it is part of the broader stormwater management infrastructure in the region. Under the US Clean Water Act, stormwater discharges from industrial activities such as mining are regulated through the National Pollutant Discharge Elimination System (NPDES). Facilities like MT. MILLS CHERT PIT must obtain permit coverage, typically under an individual permit or a general permit for stormwater associated with industrial activity. The outfall likely conveys runoff from the chert pit site, which may include sediment and other pollutants that require management through best management practices (BMPs). The facility is situated in a rural area of northwestern Alabama, where stormwater runoff can impact local waterways. Proper management of stormwater from mining operations is essential to prevent erosion, sedimentation, and potential contamination of nearby streams. The outfall's location near County Road 33 and Highway 247 suggests it drains a catchment area influenced by both mining and surrounding land uses.
Environmental context
The facility discharges stormwater from a chert mining operation in the Tennessee River watershed. Mining activities can generate sediment-laden runoff, which may affect water quality in receiving streams. The region's climate, with frequent rainfall, increases the potential for runoff events. Regulatory oversight under the Clean Water Act requires implementation of erosion and sediment controls to minimize environmental impact.
