Overview
KNOX AUTO PARTS is a stormwater outfall in Birmingham, Alabama, managing runoff from industrial and automotive parts operations under US EPA NPDES MS4 regulations.
KNOX AUTO PARTS is a stormwater outfall located at 3055 35th Avenue North in Birmingham, Jefferson County, Alabama. This facility operates within the industrial sector, handling stormwater runoff from automotive parts and repair activities. As a stormwater outfall, it is part of the broader municipal separate storm sewer system (MS4) network that manages urban runoff in the Birmingham area. The facility operates under the regulatory framework of the US Clean Water Act and the EPA's National Pollutant Discharge Elimination System (NPDES) MS4 permit program. Given its industrial catchment, the outfall is subject to stormwater pollution prevention plan (SWPPP) requirements and may need to comply with sector-specific effluent limits for industrial stormwater discharges. The NAICS codes 423140 (Motor Vehicle Parts, Used) and 811111 (General Automotive Repair) indicate a mix of warehousing and repair activities that contribute to potential pollutants in runoff. This outfall plays a role in managing stormwater quality in an urban industrial area of Birmingham. Effective stormwater management at this site helps reduce the discharge of pollutants such as oil, grease, metals, and sediments into local waterways, contributing to the protection of water resources in the Black Warrior River watershed. The facility's operational status ensures ongoing compliance with local and federal stormwater regulations.
Environmental context
Birmingham, Alabama, experiences a humid subtropical climate with frequent heavy rainfall, making stormwater management critical to prevent flooding and water pollution. The KNOX AUTO PARTS outfall discharges into an urbanized watershed that may be impaired by industrial and urban runoff. The facility's industrial catchment, including automotive parts and repair operations, poses risks of hydrocarbon, metal, and sediment contamination. Compliance with NPDES MS4 permits and implementation of best management practices (BMPs) are essential to mitigate these impacts and protect downstream water quality.
