CLEMENTS AUTO PARTS is a stormwater outfall located at 520 Pinson Valley Parkway in Birmingham, Jefferson County, Alabama, United States. The facility is operational and falls under the stormwater outfall category, managing industrial stormwater runoff from the auto parts site. As a stormwater outfall in the United States, this facility is subject to the Clean Water Act and the EPA's National Pollutant Discharge Elimination System (NPDES) permitting program. Depending on the site's industrial activities, it may be regulated under the Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The facility is located in an urbanized area of Birmingham, which likely requires compliance with Phase II MS4 permit requirements for stormwater management. The environmental significance of this outfall lies in its role in controlling the quality and quantity of stormwater runoff entering local waterways. Industrial stormwater discharges can carry pollutants such as heavy metals, oils, and sediments. Proper management helps protect the receiving water bodies in the Birmingham area, which are part of the larger Mobile Bay watershed.

The Birmingham area experiences a humid subtropical climate with frequent rainfall, making stormwater management critical. The outfall discharges into local streams that are part of the Black Warrior River watershed, which ultimately drains to Mobile Bay. Urban and industrial runoff from areas like Pinson Valley Parkway can contribute pollutants such as sediment, hydrocarbons, and metals to these water bodies. Regulatory oversight under the NPDES program aims to minimize these impacts through best management practices and monitoring.
