Overview
TUSCALOOSA AFRC/AMSA #154 is an operational stormwater outfall in Tuscaloosa, Alabama, United States. It serves as a discharge point for stormwater runoff in the area.
TUSCALOOSA AFRC/AMSA #154 is a stormwater outfall located at 10300 Alabama Highway 69 South in Tuscaloosa, Alabama. This facility is part of the stormwater management infrastructure in the region, handling runoff from urban and potentially industrial catchments. As a stormwater outfall, it discharges collected stormwater into receiving waters, playing a key role in local flood control and water quality management. The facility operates under the regulatory framework of the United States Clean Water Act, which governs stormwater discharges through the National Pollutant Discharge Elimination System (NPDES). In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, including permits for municipal separate storm sewer systems (MS4s). This outfall likely falls under a Phase II MS4 permit, given the size of Tuscaloosa, requiring implementation of best management practices to reduce pollutant loads. Located in Tuscaloosa County, this outfall discharges into local waterways that are part of the Black Warrior River watershed. The environmental significance of this facility lies in its potential impact on water quality in receiving streams, particularly during storm events when runoff can carry pollutants such as sediment, nutrients, and heavy metals. Proper management of this outfall helps protect aquatic habitats and downstream water uses.
Environmental context
Tuscaloosa is situated in the Black Warrior River watershed, which drains into the Mobile River Basin. The region experiences a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. Urban development in Tuscaloosa increases impervious surfaces, elevating runoff volumes and pollutant loads. Discharges from this outfall may affect water quality in receiving streams, particularly for sediment and nutrients, which are common concerns in Alabama waterways.
Frequently asked questions
TUSCALOOSA AFRC/AMSA #154 is located at 10300 Alabama Highway 69 South in Tuscaloosa, Alabama, United States.
A stormwater outfall is a discharge point where stormwater runoff from urban areas is released into receiving waters such as streams, rivers, or lakes. It helps manage runoff volume and can include controls to reduce pollutant loads.
Stormwater outfalls in Alabama are regulated by the Alabama Department of Environmental Management (ADEM) under the National Pollutant Discharge Elimination System (NPDES) program, which implements the Clean Water Act.
An MS4 (Municipal Separate Storm Sewer System) permit is a regulatory tool under the NPDES program that requires municipalities to implement stormwater management programs to reduce pollution in runoff. Phase II permits apply to smaller urbanized areas like Tuscaloosa.
Stormwater runoff can carry pollutants such as sediment, nutrients, heavy metals, and bacteria into water bodies, degrading water quality and harming aquatic ecosystems. Proper management of outfalls helps mitigate these impacts.
