Overview
HORN & SON CONSTRUCTION CO. is a stormwater outfall in Clarksville, Arkansas, United States. It operates under the US EPA NPDES MS4 permit framework for stormwater discharge management.
HORN & SON CONSTRUCTION CO. is a stormwater outfall located on East Main Street in Clarksville, Arkansas, within Johnson County. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, likely including construction activities and urban surfaces. The facility is operational and falls under the regulatory oversight of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) program, specifically the Municipal Separate Storm Sewer System (MS4) permits. In the United States, stormwater outfalls are regulated under the Clean Water Act to control pollution from stormwater discharges. Phase I and Phase II MS4 permits require operators to develop stormwater management programs that include best management practices (BMPs) to reduce pollutants. For a construction-related outfall like this one, compliance with the Construction General Permit (CGP) is also relevant, mandating erosion and sediment controls. The environmental significance of this outfall lies in its potential to affect local water quality. Stormwater runoff from construction sites can carry sediment, debris, and chemicals into nearby water bodies. Proper management ensures that discharges do not impair the receiving waters, which in this region may include streams and rivers within the Arkansas River basin. The facility's role is part of broader efforts to mitigate urban runoff impacts on aquatic ecosystems.
Environmental context
The outfall is located in Clarksville, Arkansas, within the Arkansas River watershed.
