  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.

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

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.

If you use hazardous solvents or degreasers, contact ND DEQ Water Quality for guidance on handling and disposal.
