MATSU ALABAMA, INC. Stormwater Outfall, Huntsville, Alabama | Industrial Stormwater Management

MATSU ALABAMA, INC. operates a stormwater outfall located at 9650 Kellner Road SW in Huntsville, Madison County, Alabama. This facility manages stormwater discharge from industrial activities, with NAICS codes indicating sectors such as heavy construction, fabricated metal manufacturing, and motor vehicle seating. As a stormwater outfall, it is part of the regulated industrial stormwater framework under the Clean Water Act. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permitting program, which requires industrial stormwater discharges to obtain coverage under a Multi-Sector General Permit (MSGP) or an individual permit. The outfall is designed to convey stormwater runoff from the industrial site to receiving waters, with treatment typically involving best management practices (BMPs) such as detention basins, oil-water separators, or filtration systems to reduce pollutant loads. Located in Huntsville, a rapidly growing city in northern Alabama, the facility contributes to local stormwater management by controlling runoff from industrial areas. Its operational status ensures compliance with federal and state regulations aimed at protecting water quality in the Tennessee River basin. The facility's role is significant for mitigating the environmental impact of industrial activities on local waterways.

The facility discharges stormwater in the Tennessee River watershed, which supports diverse aquatic ecosystems and provides drinking water for downstream communities. Industrial stormwater runoff can carry pollutants such as heavy metals, oils, and sediments, posing risks to water quality. The NPDES permit program requires monitoring and implementation of pollution prevention measures to minimize these impacts. Local water bodies may be subject to Total Maximum Daily Loads (TMDLs) for specific pollutants, influencing permit conditions.
