RAZORROCKS MATERIALS is a stormwater outfall located at 18595 Farm Hill Road in Harrisburg, Poinsett County, Arkansas, United States. The facility is operational and falls under the stormwater outfall category, serving as a discharge point for stormwater runoff from industrial activities related to mining (NAICS codes 212312, 212319, 212321). As a stormwater outfall in the United States, this facility is subject to the Clean Water Act and the EPA's National Pollutant Discharge Elimination System (NPDES) permitting program. Depending on its catchment area and discharge characteristics, it may be regulated under Phase I or Phase II MS4 permits, which require stormwater pollution prevention plans and best management practices to control runoff. The facility's location in rural Arkansas means its discharge likely enters local waterways that may be used for recreation or agriculture. Proper management of stormwater from mining operations is critical to prevent sedimentation and pollutant loading in receiving waters, supporting both environmental health and regulatory compliance.

The facility is situated in Poinsett County, Arkansas, an area with a mix of agricultural and industrial land uses. Stormwater runoff from mining operations can carry sediments, metals, and other pollutants that may impact local water quality. The receiving waters in this region are part of the Mississippi River watershed, which is ecologically significant. Regulatory oversight under the Clean Water Act aims to minimize these impacts through NPDES permits and stormwater management plans.
