The I-20/59 Exit 89 Borrow/Spoil Area is a stormwater outfall facility located on Brookwood Parkway in Vance, Tuscaloosa County, Alabama, United States. It operates under the US EPA NPDES MS4 permit system, which regulates stormwater discharges from municipal separate storm sewer systems. The facility's NAICS code 212321 indicates it serves a construction sand and gravel mining operation, suggesting the outfall manages runoff from an industrial or borrow/spoil area. As a stormwater outfall, this facility likely employs best management practices (BMPs) such as sediment basins, silt fences, or vegetative buffers to control erosion and sedimentation. In Alabama, stormwater permits are administered by the Alabama Department of Environmental Management (ADEM) under the Clean Water Act. The facility's location in a rural area near Vance suggests it handles runoff from a relatively small catchment, typical of construction or mining sites. The environmental significance of this outfall lies in its role in preventing sediment and pollutant discharge to nearby water bodies. Proper management of stormwater from borrow/spoil areas is critical to protect water quality in the Black Warrior River watershed, which supports local ecosystems and downstream communities. The facility contributes to regulatory compliance and environmental stewardship in the region.

The facility is located in the Black Warrior River watershed, which drains into the Mobile Bay estuary. Stormwater runoff from construction and mining activities can carry sediment, heavy metals, and other pollutants that impair water quality. The area experiences a humid subtropical climate with frequent heavy rainfall, increasing the risk of erosion and runoff. Effective stormwater management is essential to protect aquatic habitats and drinking water sources in the region.
