T&K Construction 5 Acre Mine Stormwater Outfall, Birmingham, Alabama

T&K Construction 5 Acre Mine is a stormwater outfall located at 2787 Alton Drive in Birmingham, Jefferson County, Alabama, United States. This facility manages stormwater runoff from a mining and construction site, classified under NAICS codes 212399 (Other Nonmetallic Mineral Mining and Quarrying) and 238910 (Site Preparation Contractors). As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory framework of the US Clean Water Act and EPA NPDES MS4 permits. Stormwater outfalls like this one are critical for controlling the quality and quantity of runoff from industrial and construction sites. In Alabama, facilities are required to obtain NPDES permits for stormwater discharges, which include monitoring and best management practices to reduce pollutants. The site's operational status is active, indicating ongoing management of stormwater to comply with local and federal regulations. The facility's location in Birmingham places it within an urban and industrial catchment, where stormwater runoff can carry sediments, metals, and other pollutants from construction activities. Proper management helps protect downstream water bodies, such as the Black Warrior River watershed, from degradation. The outfall contributes to local flood control and water quality efforts, supporting community and environmental health.

Birmingham, Alabama, has a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. The T&K Construction 5 Acre Mine site, with its mining and construction activities, generates runoff that may contain sediments and pollutants. Discharges from this outfall enter local streams that flow into the Black Warrior River, a waterbody that supports aquatic life and recreational uses. Regulatory oversight under the EPA NPDES MS4 program aims to minimize impacts through erosion control and sediment management.
