SSWA Landfill Cover Borrow Pit #6 Stormwater Outfall, Tuscumbia, Alabama

SSWA Landfill Cover Borrow Pit #6 is a stormwater outfall located in Tuscumbia, Colbert County, Alabama, United States. The facility is operational and serves as a discharge point for stormwater runoff from an undeveloped property east of a landfill unit. As a stormwater outfall, it is part of the broader stormwater management infrastructure in the region. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. Stormwater outfalls like this one are typically regulated under NPDES permits for municipal separate storm sewer systems (MS4s) or industrial stormwater permits, depending on the catchment area. The NAICS code 212399 indicates the site is associated with nonmetallic mineral mining and quarrying, which may influence the characteristics of stormwater runoff. Environmental significance of this outfall includes its role in conveying stormwater from the landfill-adjacent property to receiving waters. Proper management of stormwater from such sites is important to prevent erosion, sedimentation, and potential contamination of local waterways. The facility contributes to the stormwater drainage network in the Tennessee River basin, supporting flood control and water quality in the region.

The outfall is located in the Tennessee River watershed, which supports diverse aquatic ecosystems and provides water for municipal, industrial, and agricultural use. Stormwater runoff from the adjacent landfill and undeveloped property may carry sediments and pollutants, making proper management critical to protect water quality. The region experiences a humid subtropical climate with significant rainfall, increasing the importance of effective stormwater control to prevent flooding and erosion.
