OUACHITA RAILRAOD ARKANSAS SHORT LINE RAILROADS, INC. is a stormwater outfall facility located at 730 South Washington Avenue in El Dorado, Union County, Arkansas. As a stormwater outfall, it serves as a discharge point for stormwater runoff from railroad operations, classified under NAICS code 488210 for support activities related to rail transportation. The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) program, specifically addressing stormwater discharges from industrial activities. In the United States, stormwater outfalls associated with industrial facilities like railroads are regulated under the Clean Water Act. Facilities in this sector must obtain NPDES permits that require implementation of Stormwater Pollution Prevention Plans (SWPPPs) to control pollutants in runoff. The regulatory framework for this facility likely involves compliance with the Multi-Sector General Permit (MSGP) for industrial stormwater discharges, which includes monitoring and best management practices tailored to the railroad industry. The environmental significance of this outfall lies in its potential impact on local water bodies in the Ouachita River basin. Stormwater runoff from railroad yards can contain pollutants such as oil, grease, heavy metals, and sediments. Proper management of this outfall helps protect water quality in receiving streams and supports the broader goals of the Clean Water Act to restore and maintain the chemical, physical, and biological integrity of the nation's waters.
Environmental context
