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. Oklahoma Secretary of State Business Registration

   Mobile car wash and auto detailing businesses in Oklahoma register with the Oklahoma Secretary of State if formed as an LLC, corporation, or limited partnership.

2. Oklahoma DEQ — Stormwater Discharge Compliance (mobile car wash)

   Mobile car wash operations generate wash water containing detergents, surfactants, oils and road grime. Under the Clean Water Act stormwater program that the Oklahoma Department of Environmental Quality administers, discharging this wash water to storm drains, street gutters or waterways is prohibited. Operators should contain runoff with a berm or mat, recover the water with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer or a licensed facility. This is a compliance obligation, not a purchasable permit product — DEQ publishes no mobile car wash registration.

1. No City of Norman General Business License Required

   Norman does not require a general business license. City licensing is category-specific — alcohol, food service and mobile food, medical marijuana, massage therapy/bodywork establishments, kennels, taxis/pedicabs/salvage yards/impoundment yards, pawnbrokers, solicitors and peddlers, coin-operated machines, special events, and bee keeping — and mobile car wash or auto detailing is not among them. Standard registration is an Oklahoma Tax Commission sales tax permit, plus home-occupation zoning compliance if operating from a residence.
