LKQ Pick Your Part Stormwater Outfall, Huntsville, Alabama

LKQ Pick Your Part is a stormwater outfall located at 6942 Stringfield Rd., Huntsville, Alabama, in Madison County. The facility is operational and manages stormwater runoff from an automotive recycling and parts sales operation, classified under NAICS codes 441310 and 441330. As a stormwater outfall, it discharges collected runoff into local waterways, subject to the regulatory framework of the US Clean Water Act and EPA's NPDES MS4 permit program. The facility operates within the Tennessee Valley region, where stormwater management is critical due to the area's humid subtropical climate with frequent thunderstorms. The outfall likely serves an industrial catchment, requiring compliance with stormwater pollution prevention plans (SWPPP) and best management practices (BMPs) to control pollutants such as sediment, oil, and heavy metals typical of automotive facilities. Huntsville's rapid urban growth adds pressure on stormwater infrastructure to manage increased runoff volumes. Environmental significance lies in the outfall's potential impact on receiving waters in the Tennessee River basin. Proper operation helps prevent flooding and protects water quality in local streams and the Tennessee River. The facility's compliance with NPDES permit conditions is essential for minimizing pollutant loads from industrial activities, supporting the broader goal of maintaining healthy aquatic ecosystems in the region.

The stormwater outfall discharges into the Tennessee River watershed, which supports diverse aquatic life and provides drinking water for the region. Huntsville's urban and industrial development increases impervious surfaces, elevating runoff volumes and pollutant loads. The facility's industrial catchment, involving automotive recycling, poses risks of oil, grease, metals, and sediment entering waterways. Effective stormwater management through BMPs and regular monitoring is crucial to mitigate these impacts and maintain compliance with the Clean Water Act.
