CAPITAL SAND COMPANY, INC.--HARRISBURG NORTH is a stormwater outfall located at 18800 Massengill Road in Harrisburg, Arkansas, within Poinsett County. This facility manages stormwater runoff from industrial operations associated with NAICS codes 212312 (Crushed and Broken Limestone Mining), 212319 (Other Crushed and Broken Stone Mining and Quarrying), and 212321 (Construction Sand and Gravel Mining). As a stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, specifically under the Clean Water Act. The facility operates under the NPDES Multi-Sector General Permit (MSGP) for industrial stormwater discharges. This permit requires implementation of stormwater pollution prevention plans (SWPPPs) and best management practices (BMPs) to control pollutants from the industrial site. The outfall likely discharges to nearby surface waters, which may include streams or rivers in the Mississippi River basin. Compliance with monitoring and reporting requirements is essential to minimize environmental impact. As an industrial stormwater outfall, this facility plays a role in managing runoff from mining and construction material operations. Effective stormwater management helps prevent sediment, metals, and other pollutants from entering local waterways. The facility's location in Arkansas, a state with significant agricultural and natural resources, underscores the importance of controlling industrial runoff to protect water quality and aquatic habitats.
Environmental context
The facility is located in Poinsett County, Arkansas, within the Mississippi Alluvial Plain ecoregion. This area is characterized by flat topography and intensive agriculture, making surface waters sensitive to sediment and nutrient pollution. Industrial stormwater discharges from mining operations can introduce suspended solids, metals, and hydrocarbons into local streams. The outfall likely drains to the Cache River or its tributaries, which are part of the Mississippi River watershed. Effective stormwater management is critical to prevent impairment of these water bodies, which support diverse aquatic life and are used for recreation and irrigation.
