  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. North Dakota Business Registration

    Mobile car wash and auto detailing businesses operating in North Dakota must register with the North Dakota Secretary of State if structured as an LLC, corporation, or partnership (LLC registration fee is a flat $135).

  2. North Dakota Stormwater Discharge Compliance (Mobile Car Wash)

    Mobile car wash wastewater carries detergents, surfactants, oils and road grime. Consistent with the federal Clean Water Act, North Dakota and its cities prohibit discharging that water to storm drains, street gutters or waterways. Contain wash water with a mat or berm, recover it with a wet/dry vacuum or pump, and route it to a sanitary sewer or an approved disposal facility. ND DEQ issues no permit to mobile car wash operators — its NDPDES stormwater permits cover construction sites and industrial facilities. If you use hazardous solvents or degreasers, contact ND DEQ Water Quality for guidance on handling and disposal.

    Official government source

    No permit or registration fee — this is an operating requirement, not a licensed permit.No application to file; have containment and disposal arranged before your first job.

  3. North Dakota Sales and Use Tax Permit

    Car washing and auto detailing services are subject to North Dakota sales tax. Register for a sales and use tax permit with the Office of State Tax Commissioner through the ND Taxpayer Access Point (ND TAP), then collect and remit state and applicable local sales tax. Keep records of all transactions and file returns on the schedule the Tax Commissioner assigns.

  1. No City of Bismarck Business License Required

    Bismarck does not issue a general business license. The city states: "The City of Bismarck does not presently have a general business license, however certain occupations may require a license or permit, specific to that use, to operate." Mobile car wash and auto detailing are not among the licensed activities (food service, gaming, liquor sales, excavation and concrete work, taxis), so no city business license applies.

    No fee — no city license exists for this business type.No application to file.

  2. Bismarck Stormwater Discharge Compliance

    Bismarck operates a municipal separate storm sewer system (MS4) under an ND DEQ permit, and non-stormwater discharges such as car wash water are not allowed into storm drains, gutters, or waterways. The city does not issue a permit to mobile car wash operators. Capture wash water with a containment mat or berm, recover it with a wet/dry vacuum or pump, and dispose of it to the sanitary sewer or an approved disposal facility.
