Green Source Recycling-West River Valley RSWMD Stormwater Outfall, Clarksville, Arkansas

Green Source Recycling-West River Valley RSWMD is a stormwater outfall located at 24087 Highway 164 in Clarksville, Arkansas, within Johnson County. This facility manages stormwater runoff from an industrial recycling operation, classified under NAICS 423930 (Recyclable Material Merchant Wholesalers). As a stormwater outfall, it discharges collected runoff into local waterways, playing a key role in managing urban and industrial stormwater in the region. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. While Arkansas is not a Phase I MS4 state for large municipalities, smaller MS4s in urbanized areas are subject to Phase II regulations. The outfall likely requires a permit to ensure discharges meet water quality standards and do not impair receiving waters. Environmental significance lies in its location within the Arkansas River watershed, where stormwater runoff from industrial sites can carry pollutants such as heavy metals, sediments, and chemicals. Proper management of this outfall helps protect local water bodies from contamination, supporting aquatic ecosystems and downstream water uses. The facility's operational status indicates ongoing compliance with regulatory requirements.

The facility is situated in the Arkansas River Valley, a region characterized by a humid subtropical climate with significant seasonal rainfall. Stormwater runoff from industrial sites like this recycling facility can introduce pollutants such as metals, oils, and sediments into nearby streams and rivers. The Arkansas River and its tributaries are vital for drinking water, recreation, and aquatic habitat, making stormwater management critical to preventing impairment of these water bodies.
