Overview
GREDE II LLC MARION is an operational stormwater outfall in Marion, Alabama, United States. It manages stormwater discharge from an industrial catchment under the US EPA NPDES MS4 regulatory framework.
GREDE II LLC MARION is a stormwater outfall located at County Road 45 South in Marion, Perry County, Alabama, United States. This facility manages stormwater runoff from an industrial catchment, operating under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) and the Clean Water Act. As a stormwater outfall, it serves as a discharge point for collected stormwater, which may be subject to local MS4 permit requirements depending on the municipality's designation. The facility operates in the context of Alabama's stormwater management regulations, which align with federal Phase I and Phase II MS4 permits. While specific technical specifications such as discharge volume are not detailed, the facility's industrial catchment suggests potential for pollutants like sediment, heavy metals, or hydrocarbons. Typical stormwater outfalls in industrial settings employ best management practices (BMPs) such as retention basins, oil-water separators, or filtration systems to mitigate environmental impacts. Environmental significance lies in its role in managing urban and industrial runoff, which can affect local water bodies. The facility's discharge may flow into the Cahaba River watershed or nearby tributaries, supporting regional water quality goals. Compliance with NPDES permits ensures that stormwater discharges meet established limits, protecting aquatic ecosystems and downstream communities.
Environmental context
The facility is located in Perry County, Alabama, within the Black Belt region characterized by clay soils and agricultural land use. Stormwater runoff from industrial catchments can carry pollutants such as sediment, metals, and hydrocarbons, potentially impacting local streams and the Cahaba River. The area's hydrology is influenced by seasonal rainfall patterns, with high-intensity storms increasing runoff volumes. Regulatory oversight under the Clean Water Act and NPDES MS4 permits aims to control these discharges to protect water quality and aquatic habitats.
