CARRY TRANSIT, LLC Stormwater Outfall in Decatur, Alabama | Industrial Runoff Management

CARRY TRANSIT, LLC is a stormwater outfall located at 1304 State Docks Road in Decatur, Morgan County, Alabama. The facility is operational and classified under NAICS codes 484230 (specialized freight trucking) and 485999 (other transit and ground passenger transportation), indicating an industrial catchment area. As a stormwater outfall, it manages runoff from transportation and logistics operations, discharging into local waterways. In the United States, stormwater outfalls like this one are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Phase I and Phase II MS4 permits require operators to develop stormwater management programs to reduce pollutant discharges. Facilities in industrial sectors, such as transportation, often need to comply with specific effluent guidelines and best management practices to control runoff. The environmental significance of this outfall lies in its role in managing stormwater from an industrial area near the Tennessee River. Proper management helps prevent pollutants like sediment, oil, and heavy metals from entering water bodies, protecting aquatic ecosystems and downstream water quality. The facility's location in Decatur, a hub for transportation and manufacturing, underscores the importance of effective stormwater control in urban-industrial settings.

The outfall discharges into the Tennessee River watershed, which supports diverse aquatic life and provides drinking water for downstream communities. Industrial stormwater runoff from transportation activities can carry pollutants such as hydrocarbons, heavy metals, and suspended solids. Effective management is critical to prevent impairment of water quality and to comply with Total Maximum Daily Load (TMDL) requirements for the watershed.
