R & R READY MIX Stormwater Outfall, Hardy, Arkansas | United States

R & R READY MIX is a stormwater outfall facility located at 3185 HWY 62/US412 in Hardy, Sharp County, Arkansas, United States. The facility is operational and classified under NAICS code 327390, which corresponds to ready-mix concrete manufacturing. As a stormwater outfall, it manages runoff from industrial activities associated with concrete production. In the United States, stormwater discharges from industrial facilities are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES). Facilities like R & R READY MIX are typically required to obtain coverage under an NPDES industrial stormwater permit, which mandates the development of a Stormwater Pollution Prevention Plan (SWPPP) and implementation of best management practices to control pollutants in runoff. The facility's location in Hardy, Arkansas, places it within the Mississippi River watershed. Stormwater management at concrete manufacturing sites often focuses on controlling sediment, pH, and other pollutants common to construction materials. Compliance with permit conditions helps protect local water quality and downstream ecosystems.

The facility is located in Sharp County, Arkansas, within the Ozark Highlands ecoregion. This area features karst topography with porous limestone bedrock, making groundwater particularly vulnerable to contamination from surface runoff. Stormwater discharges from industrial sites like concrete batch plants can carry high pH levels, suspended solids, and metals, which may impact nearby streams and aquifers. Effective stormwater management is critical in this region to protect both surface water and groundwater resources.
