RWS Materials Pit Stormwater Outfall, Pike Road, Alabama | United States

RWS Materials Pit is a stormwater outfall located in Pike Road, Montgomery County, Alabama, United States. It serves a construction sand and gravel mining facility (NAICS 212321), managing stormwater runoff from the industrial site. The outfall is operational and falls under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES) for stormwater discharges associated with industrial activities. As a stormwater outfall for a mining operation, the facility is subject to the Clean Water Act and Alabama's water quality standards. The outfall likely handles runoff from disturbed areas, stockpiles, and haul roads, with typical best management practices including sediment basins, silt fences, and vegetative buffers to control erosion and sedimentation. The scale of the operation is consistent with a medium-sized mining site in the region. The environmental significance of RWS Materials Pit lies in its role in preventing sediment and pollutant discharges to nearby waterbodies. Proper stormwater management at mining sites is critical to protect aquatic habitats and downstream water quality. The facility's compliance with NPDES permit conditions helps mitigate impacts on local streams and rivers in the Alabama River basin.

The facility is located in the Alabama River basin, which supports diverse aquatic ecosystems. Stormwater runoff from mining operations can carry sediment, metals, and other pollutants that may impair water quality. The outfall's discharge is regulated under the Clean Water Act to prevent degradation of receiving waters. Effective stormwater management is essential to protect downstream habitats and maintain compliance with Total Maximum Daily Load (TMDL) requirements for impaired waterbodies in the region.
