THERMO-TILE is a stormwater outfall located at 1030 E Main Street in Clarksville, Johnson County, Arkansas, United States. The facility is operational and serves as a discharge point for stormwater runoff from an industrial site classified under NAICS 453930 (Manufactured Home Dealers). As a stormwater outfall, it is part of the broader network of regulated point sources under the National Pollutant Discharge Elimination System (NPDES). The facility operates under the regulatory framework of the US Clean Water Act, which requires industrial stormwater discharges to be covered by NPDES permits. In Arkansas, the Department of Energy and Environment - Division of Environmental Quality oversees permit compliance. The outfall likely handles runoff from impervious surfaces such as parking lots and rooftops, with typical flow rates varying based on rainfall intensity and catchment area. Stormwater outfalls like THERMO-TILE play a critical role in managing urban runoff and preventing flooding. They also help protect local water quality by conveying stormwater to receiving waters, which in this region may include tributaries of the Arkansas River. Proper maintenance and compliance with permit conditions are essential to minimize pollutant loads and meet water quality standards.

The outfall is located in Clarksville, a city in the Arkansas River Valley. The region experiences a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. The receiving waters may be sensitive to pollutants from industrial areas, including sediment, heavy metals, and hydrocarbons. Regulatory oversight under the NPDES program aims to control these discharges through best management practices and monitoring.
