Overview
HANWHA ADVANCED MATERIALS AMERICA, LLC operates a stormwater outfall in Opelika, Alabama, managing industrial stormwater discharges under US EPA NPDES MS4 regulations.
HANWHA ADVANCED MATERIALS AMERICA, LLC is an industrial facility located at 4400 North Park Drive in Opelika, Lee County, Alabama. The site operates a stormwater outfall that manages runoff from industrial activities, classified under NAICS codes including 236210 (industrial building construction), 326130 (laminated plastics), 326199 (other plastics product manufacturing), and 336390 (other motor vehicle parts manufacturing). As a stormwater outfall in the United States, the facility is subject to the Clean Water Act and EPA's NPDES MS4 permit program, which regulates discharges from industrial and municipal separate storm sewer systems. The facility's stormwater management is part of Alabama's broader regulatory framework under the Alabama Department of Environmental Management (ADEM). Industrial stormwater outfalls like this one typically require permits that outline best management practices (BMPs) for controlling pollutants in runoff. The site's location in an urban-industrial area of Opelika means stormwater may carry contaminants from manufacturing processes, parking lots, and other impervious surfaces. Operationally, the outfall discharges into local waterways that ultimately flow into the Chattahoochee River basin. Effective stormwater management at this facility helps protect water quality in receiving streams, particularly given the industrial nature of the catchment. The facility's compliance with its NPDES permit is critical for minimizing environmental impact and supporting community water resources.
Environmental context
The facility is located in Opelika, Alabama, within the Chattahoochee River watershed. Industrial stormwater discharges from this site may affect local water bodies that are subject to Total Maximum Daily Load (TMDL) requirements for pollutants such as sediment, nutrients, and metals. The urban-industrial catchment increases runoff volumes and pollutant loads, making stormwater management crucial for maintaining water quality standards under the Clean Water Act.
