PPG INDUSTRIES INC. Stormwater Outfall, Huntsville, Alabama | Industrial Stormwater Management

PPG INDUSTRIES INC. is an industrial stormwater outfall located at 1719 Highway 72 East in Huntsville, Alabama. The facility manages stormwater runoff from industrial operations, categorized under NAICS codes 326199 (other plastics product manufacturing) and 327215 (glass product manufacturing). As a stormwater outfall, it is subject to the US EPA National Pollutant Discharge Elimination System (NPDES) permitting program, specifically under the Multi-Sector General Permit (MSGP) for industrial activities. The facility operates within the regulatory framework of the Clean Water Act, which requires industrial stormwater discharges to obtain NPDES permit coverage. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program. The outfall likely serves an industrial catchment area, with runoff potentially containing pollutants such as sediment, chemicals, or metals from manufacturing processes. Typical stormwater management practices include detention basins, oil-water separators, and erosion controls. Located in Huntsville, a rapidly growing city in Madison County, the facility contributes to local stormwater management by controlling runoff from industrial sites. The environmental significance lies in preventing untreated industrial runoff from entering nearby water bodies, such as the Tennessee River or its tributaries. Compliance with permit conditions ensures protection of water quality and aquatic habitats in the region.

The facility is located in Huntsville, Alabama, within the Tennessee River watershed. The region experiences a humid subtropical climate with frequent rainfall, making stormwater management critical for preventing flooding and water pollution. Industrial stormwater discharges can carry pollutants like heavy metals, oils, and suspended solids, which may impact local streams and the Tennessee River. Regulatory oversight under the Clean Water Act and ADEM ensures that the facility implements best management practices to minimize environmental harm.
