Overview
Washington County Road Department operates a stormwater outfall in Fayetteville, Arkansas, managing runoff from road infrastructure under EPA MS4 permit requirements.
Washington County Road Department operates a stormwater outfall located at 19299 Pando Place Road in Fayetteville, Arkansas. This facility manages stormwater runoff from road maintenance and construction activities, serving the transportation infrastructure of Washington County. As a municipal separate storm sewer system (MS4) operator, it falls under Phase II of the EPA's NPDES permitting program. The facility's operations are governed by the Clean Water Act, requiring compliance with stormwater pollution prevention plans and best management practices. The NAICS code 212321 indicates involvement in construction sand and gravel mining, suggesting the outfall may handle runoff from aggregate operations or road construction sites. Typical stormwater management includes sediment basins, detention ponds, and erosion control measures. Environmental significance lies in protecting local water quality in the Arkansas River Basin. The outfall discharges into receiving waters that may be impaired by urban runoff, necessitating careful monitoring of pollutants like sediment, oil, and heavy metals. Proper management helps maintain aquatic habitat and drinking water sources in the region.
Environmental context
Fayetteville is located in the Ozark Mountains ecoregion, characterized by karst topography with limestone bedrock and numerous springs. Stormwater runoff in this area can rapidly infiltrate groundwater, posing risks to drinking water aquifers and sensitive cave ecosystems. The region receives about 48 inches of annual rainfall, with intense thunderstorms common in spring and summer. Urban development and road construction increase impervious surfaces, elevating runoff volumes and pollutant loads to streams like the West Fork of the White River.
