Overview
SRM Plant #510 is a stormwater outfall located in Huntsville, Alabama, United States. It operates under the EPA NPDES MS4 permit framework for stormwater management.
SRM Plant #510 is a stormwater outfall facility situated at 100 Pegram Street in Huntsville, Madison County, Alabama. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding urban catchment. The facility is operational and falls under the regulatory oversight of the U.S. Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. Stormwater outfalls like SRM Plant #510 are critical components of urban drainage infrastructure, designed to convey stormwater runoff from streets, parking lots, and other impervious surfaces to receiving water bodies. In Huntsville, which is part of the Tennessee Valley region, stormwater management is essential due to the area's hilly terrain and frequent thunderstorms. The facility likely serves a medium-sized urban catchment, typical of Phase II MS4 communities. The environmental significance of SRM Plant #510 lies in its role in managing stormwater quality and quantity. Discharges from stormwater outfalls can carry pollutants such as sediment, nutrients, heavy metals, and pathogens into local waterways. The facility operates under a permit that requires compliance with water quality standards and implementation of best management practices to reduce pollution. Its location in Huntsville, a growing city with a mix of residential, commercial, and industrial areas, underscores the importance of effective stormwater management to protect downstream water bodies.
Environmental context
The facility discharges stormwater into the Tennessee River watershed, which is a major water resource in the southeastern United States. Urban runoff from Huntsville can contribute to elevated levels of sediment, nutrients, and heavy metals, potentially impacting aquatic habitats and water quality. The area experiences a humid subtropical climate with intense rainfall events, increasing the risk of flooding and pollutant transport. Regulatory compliance under the NPDES MS4 program requires the facility to implement stormwater control measures to mitigate these impacts.
Frequently asked questions
