Overview
Steward Machine Company, Inc. (Plant 1) is an operational stormwater outfall in Birmingham, Alabama, discharging industrial stormwater under US EPA NPDES MS4 regulations.
Steward Machine Company, Inc. (Plant 1) is a stormwater outfall located at 3911 13th Avenue North in Birmingham, Jefferson County, Alabama. The facility operates within the United States under the jurisdiction of the Clean Water Act and the EPA's National Pollutant Discharge Elimination System (NPDES) MS4 permit program, which regulates stormwater discharges from industrial facilities. The facility's NAICS code 332710 indicates it is part of the machine shops industry, which typically involves metalworking and machining operations. Stormwater runoff from such industrial sites can contain pollutants like metals, oils, and sediments. The outfall likely discharges to a local waterbody, and the facility must comply with stormwater pollution prevention plan (SWPPP) requirements and monitoring obligations under its NPDES permit. As an industrial stormwater outfall in Birmingham, this facility contributes to the management of urban runoff in a city with a significant industrial history. Proper stormwater control helps protect downstream water quality in the Black Warrior River watershed and supports compliance with Total Maximum Daily Load (TMDL) requirements for impaired waterbodies in the region.
Environmental context
Birmingham, Alabama, has a humid subtropical climate with frequent rainfall, making stormwater management critical for preventing flooding and pollution. The facility's industrial catchment (machine shop) poses risks of metal and hydrocarbon runoff. Discharges may affect local streams that are part of the Black Warrior River basin, which has segments listed as impaired under Section 303(d) of the Clean Water Act. Compliance with NPDES permit conditions, including best management practices (BMPs) and monitoring, is essential to minimize environmental impact.
