Overview
Metalplate Galvanizing LP operates a stormwater outfall in Birmingham, Alabama, managing runoff from industrial metal coating operations under US EPA NPDES MS4 regulations.
Metalplate Galvanizing LP is an industrial stormwater outfall located at 757 44th Street North in Birmingham, Jefferson County, Alabama. The facility is operational and falls under the jurisdiction of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which regulates stormwater discharges from industrial activities. As a metal coating facility (NAICS 332812), it manages runoff from galvanizing operations, a sector with potential for heavy metal and chemical contaminants. The facility operates within Alabama's regulatory framework, which requires industrial stormwater permits under the Clean Water Act. Typical stormwater management at such sites includes best management practices (BMPs) like sediment basins, oil-water separators, and regular monitoring for pollutants such as zinc, lead, and pH. The outfall discharges into local waterways that ultimately feed into the Black Warrior River basin, a region with mixed urban and industrial land use. Environmental significance lies in the facility's role in preventing untreated industrial runoff from reaching sensitive water bodies. Birmingham's industrial history and current urban density make stormwater management critical for protecting water quality in the Cahaba River and surrounding ecosystems. Compliance with NPDES permit conditions helps mitigate risks to aquatic life and downstream communities.
Environmental context
Birmingham, Alabama, has a humid subtropical climate with frequent thunderstorms, leading to high stormwater runoff volumes. The area's industrial legacy, including metal fabrication and galvanizing, contributes potential pollutants like zinc, lead, and oils to stormwater. Discharges from this outfall enter the Black Warrior River watershed, which supports diverse aquatic habitats and is used for recreation and drinking water. Effective stormwater management is essential to prevent impairment of these water bodies from industrial contaminants.
