ARONDA MANUFACTURING INC. Stormwater Outfall, Clarksville, Arkansas | Industrial Stormwater Management

ARONDA MANUFACTURING INC. is an industrial facility located at 1446 CR 3291 in Clarksville, Johnson County, Arkansas, United States. The facility operates a stormwater outfall that discharges industrial stormwater runoff, regulated under the National Pollutant Discharge Elimination System (NPDES) Multi-Sector General Permit (MSGP) for industrial activities. As a manufacturing plant with NAICS code 336612 (Boat Building), it falls under Sector S (Ship and Boat Building and Repairing) of the MSGP. The facility's stormwater outfall is subject to stormwater pollution prevention plan (SWPPP) requirements, including best management practices (BMPs) for controlling pollutants in runoff. Typical BMPs for this sector include containment of materials, spill prevention, and regular site inspections. The outfall discharges to local waterways in the Arkansas River basin, which may be subject to Total Maximum Daily Load (TMDL) requirements for pollutants such as sediment, metals, or hydrocarbons. Environmental significance includes potential impacts on receiving water quality in Johnson County. Industrial stormwater discharges can carry pollutants like oil, grease, heavy metals, and debris. Compliance with NPDES permit conditions, including monitoring and reporting, is critical to protect aquatic ecosystems and downstream uses. The facility's location in a rural area may reduce some risks, but industrial activities require ongoing management to prevent unauthorized releases.

The facility is located in the Arkansas River watershed, which supports diverse aquatic habitats and is used for recreation and water supply. Industrial stormwater discharges from manufacturing facilities can introduce pollutants such as metals, hydrocarbons, and sediment. The region experiences seasonal rainfall, with potential for high-intensity storms that increase runoff volumes and pollutant loading. Effective stormwater management is essential to prevent degradation of water quality and comply with Clean Water Act requirements.
