Overview
Walker Gravel and Excavating Carrollton Pit is a stormwater outfall in Carrollton, Alabama, United States. It serves an industrial gravel mining operation under the US EPA NPDES MS4 regulatory framework.
Walker Gravel and Excavating Carrollton Pit is a stormwater outfall located at 15501 AL86 in Carrollton, Pickens County, Alabama, United States. The facility is operational and serves an industrial gravel mining operation, classified under NAICS code 212321 (Construction Sand and Gravel Mining). As a stormwater outfall, it manages runoff from the mining site, discharging into local waterways. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) program, which regulates stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, including permits for stormwater associated with industrial activity. The site likely holds a Multi-Sector General Permit (MSGP) for the construction sand and gravel mining sector, which requires implementation of best management practices to control pollutants in runoff. As a gravel mining operation, the environmental significance of this stormwater outfall lies in managing sediment-laden runoff, which can impact water quality in receiving streams. Proper erosion and sediment control measures are critical to prevent siltation and protect aquatic habitats. The facility's location in rural Pickens County means discharges may affect small streams that feed into larger water bodies in the region.
Environmental context
The Carrollton Pit is located in a rural area of Pickens County, Alabama, within the Black Warrior River watershed. Stormwater runoff from gravel mining operations can carry high sediment loads, potentially impairing water quality in nearby streams. The facility must comply with NPDES permit requirements to minimize erosion and sedimentation, protecting aquatic ecosystems and downstream water uses.
Frequently asked questions
The facility is located at 15501 AL86 in Carrollton, Pickens County, Alabama, United States.
It is a stormwater outfall associated with a construction sand and gravel mining operation (NAICS 212321).
The facility is subject to the US EPA NPDES program, likely under the Multi-Sector General Permit for industrial stormwater discharges, administered by the Alabama Department of Environmental Management.
The primary concern is sediment-laden runoff, which can cause siltation in receiving waters, harming aquatic habitats and water quality. Proper erosion and sediment control measures are essential.
The NPDES program requires industrial facilities to obtain permit coverage, develop a Stormwater Pollution Prevention Plan (SWPPP), implement best management practices, and monitor discharges to minimize pollution.
