SMITH'S READY MIX, INC Stormwater Outfall, Arkadelphia, Arkansas

SMITH'S READY MIX, INC is a stormwater outfall located at 146 Malvern Road in Arkadelphia, Clark County, Arkansas. This facility manages stormwater runoff from a ready-mix concrete manufacturing operation, classified under NAICS code 327320. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state stormwater regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) framework, which requires industrial facilities to obtain permit coverage for stormwater discharges. In Arkansas, the Department of Energy and Environment - Division of Environmental Quality administers these permits. The outfall likely falls under the Multi-Sector General Permit (MSGP) for industrial activities, which mandates best management practices (BMPs) and monitoring to control pollutants such as sediment, concrete washout, and other construction-related contaminants. Stormwater outfalls like this one play a critical role in preventing untreated runoff from entering nearby water bodies. The ready-mix concrete industry poses specific risks due to alkaline wastewater and suspended solids. Proper management ensures compliance with water quality standards and protects local streams and rivers in the Ouachita River basin, which supports regional ecosystems and community water supplies.

The facility is located in Arkadelphia, Arkansas, within the Ouachita River watershed. The region experiences a humid subtropical climate with frequent rainfall, increasing the potential for stormwater runoff. The ready-mix concrete operation generates runoff containing high pH levels, total suspended solids, and trace metals. Discharge to impaired water bodies could exacerbate local water quality issues. Regulatory oversight under the Clean Water Act and Arkansas stormwater permits aims to mitigate these impacts through erosion controls, sediment basins, and regular monitoring.
