2. EPA Stormwater Compliance — Clean Water Act Section 402

   Mobile car wash operations that discharge wash water are subject to the federal Clean Water Act. The EPA's National Pollutant Discharge Elimination System (NPDES) prohibits discharge of polluted wash water to storm drains or waterways without a permit. Most mobile operators achieve compliance by using containment systems and disposing of water via sanitary sewer. Larger operations (e.g., fleet washing facilities) may require an NPDES permit.

1. Arkansas Secretary of State Business Filing

   A mobile car wash or auto detailing business organized as an LLC, corporation, or limited partnership registers with the Arkansas Secretary of State's Business and Commercial Services Division.

Code 4-70-203, not with the Secretary of State. Arkansas does not mandate any particular entity type for this trade.

2. Arkansas DEQ Water Quality Rules for Mobile Car Wash Wastewater

   Wash water from mobile car washing carries detergents, surfactants, oils, and road grime, and discharging it to a storm drain, street gutter, or waterway is not authorized. The Arkansas Division of Environmental Quality's Office of Water Quality administers the state's NPDES program, covering wastewater, construction, stormwater, and pretreatment permits, plus no-discharge permits. DEQ publishes no permit category for mobile car washing: an operator who captures wash water with a containment mat and a wet/dry vacuum or pump and disposes of it to the sanitary sewer, with the local sewer utility's approval, is not discharging to waters of the state and needs no individual permit. Contact the Office of Water Quality before operating if hazardous solvents or degreasers are involved.

3. Arkansas Sales and Use Tax Permit for Vehicle Cleaning Services

   Cleaning of motor vehicles is a taxable service under Ark. Code 26-52-301, so a mobile car wash or auto detailing business must hold an Arkansas sales and use tax permit and collect the 6.500% state rate plus local city and county rates from customers. The permit is issued by the Department of Finance and Administration; Arkansas has no 'Department of Revenue'. The separate car wash water usage fee under Ark. Code 26-57-1602 and 26-57-1603, which is paid in lieu of sales tax, applies only to operators of automatic car washes and car wash tunnels, so a mobile hand-wash or detailing operation stays in the ordinary sales tax system. Keep transaction records and remit on the schedule DFA assigns.
