OWENS CORNING COMPOSITE MATERIALS LLC Stormwater Outfall, Fort Smith, Arkansas

OWENS CORNING COMPOSITE MATERIALS LLC manages a stormwater outfall located at 5520 Planters Road in Fort Smith, Arkansas. This facility handles stormwater runoff from industrial operations, including composite materials manufacturing, and is classified under multiple NAICS codes such as 236210, 238160, 313230, 327212, and 327993. As a stormwater outfall, it plays a critical role in controlling the discharge of runoff into local waterways. The facility operates under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES), specifically the MS4 permit program for industrial stormwater discharges. In Arkansas, the Department of Energy and Environment oversees compliance with the Clean Water Act, ensuring that stormwater outfalls like this one meet water quality standards. The outfall likely serves a large industrial catchment area, given the diverse manufacturing activities on site. Environmental significance lies in the outfall's potential impact on receiving waters in the Arkansas River basin. Proper management of stormwater runoff is essential to prevent pollutants such as sediment, chemicals, and debris from entering local streams. The facility's compliance with NPDES permits helps protect aquatic ecosystems and downstream water users in the Fort Smith region.

The stormwater outfall discharges into the Arkansas River watershed, which supports diverse aquatic life and provides drinking water for communities. Industrial runoff from composite materials manufacturing can contain pollutants like heavy metals, oils, and suspended solids. Regulatory oversight under the Clean Water Act and NPDES MS4 permits aims to minimize these impacts through best management practices and monitoring.
