Circle City Transport, Inc. Stormwater Outfall, Dothan, Alabama | US Stormwater Facility

Circle City Transport, Inc. is a stormwater outfall facility located at 2657 Trawick Road in Dothan, Houston County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from a transportation-related site, classified under NAICS code 484110 (General Freight Trucking, Local). As a stormwater outfall, it is subject to the US Clean Water Act and National Pollutant Discharge Elimination System (NPDES) regulations, specifically under the Municipal Separate Storm Sewer System (MS4) permit program. The facility operates within the regulatory framework of the US EPA's Phase II MS4 rules, which apply to small municipalities and industrial sites in urbanized areas. Dothan, as part of the broader Houston County region, is likely covered by a Phase II MS4 permit requiring stormwater management practices to reduce pollutant discharges. The outfall likely conveys runoff from impervious surfaces such as parking lots, loading areas, and roadways, which may carry pollutants like sediment, oil, grease, and heavy metals. Stormwater outfalls like Circle City Transport, Inc. play a critical role in managing urban runoff to protect local water quality. The facility's discharge may ultimately reach nearby water bodies, such as the Choctawhatchee River watershed, which supports aquatic ecosystems and downstream communities. Effective stormwater management at this site helps mitigate flooding, erosion, and pollution, aligning with the goals of the Clean Water Act to restore and maintain the chemical, physical, and biological integrity of the nation's waters.

Dothan, Alabama, is located in the southeastern United States, characterized by a humid subtropical climate with high annual rainfall, often exceeding 50 inches per year. This precipitation generates significant stormwater runoff, particularly from impervious surfaces in urban and industrial areas. The region's water bodies, including the Choctawhatchee River and its tributaries, are susceptible to pollution from stormwater discharges carrying sediments, nutrients, and industrial contaminants. Regulatory oversight under the US EPA's NPDES MS4 program aims to control these discharges through best management practices and monitoring to protect aquatic habitats and downstream water quality.
