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. New Mexico Business Registration

   Mobile car wash and auto detailing businesses operating in New Mexico must register with the New Mexico Secretary of State if structured as an LLC, corporation, or partnership. Sole proprietors using a trade name must file a DBA registration. An LLC is recommended to protect personal assets, as mobile operations working at customers' properties carry inherent liability.

2. New Mexico Environmental / Stormwater Compliance

   Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. New Mexico environmental regulations — consistent with federal Clean Water Act requirements — prohibit discharge of this wash water to storm drains, street gutters, or waterways. Operators must use a wastewater containment mat and recovery system (wet/dry vacuum or pump), or must ensure wash water flows to a sanitary sewer inlet. Operators using hazardous cleaning solvents or degreasers may require a state permit. Contact the New Mexico Department of Environmental Quality for compliance guidance.

3. New Mexico Sales Tax Registration

   New Mexico has no conventional 'sales tax' or seller's permit — car-wash and detailing receipts are taxable under the state's GROSS RECEIPTS TAX, which applies to services broadly. Register (free) with the New Mexico Taxation and Revenue Department for a Business Tax Identification Number and remit at your location-code rate.

2. Santa Fe Stormwater / Wastewater Discharge Compliance

   Santa Fe prohibits the discharge of mobile car wash wastewater into storm drains, gutters, or waterways. Wash water contains detergents, oils, and road grime that are harmful to local waterways. Operators must: (1) use a portable containment berm or mat to capture runoff, (2) vacuum up wash water with a wet/dry vac or pump, and (3) dispose of collected water at an approved sanitary sewer access point or licensed disposal facility. The city's Public Works or Stormwater division may conduct inspections. Violations may result in fines.

3. Santa Fe County Environmental Health — Chemical Use Registration (if applicable)

   New Mexico does not have a county-level hazardous-materials/chemical-use registration program for mobile detailing businesses (unlike California's CUPA system). Businesses using cleaning chemicals, degreasers, or solvents must still maintain Safety Data Sheets and follow general OSHA/manufacturer storage-and-disposal guidance, and must comply with Santa Fe's wastewater/stormwater discharge prohibitions (see separate stormwater compliance requirement) -- but there is no separate county chemical-use registration to apply for. Confirm with Santa Fe County Growth Management if a specific site plan requires otherwise.

4. Santa Fe Business License for Home-Based Business (if operating from residence)

   Mobile car wash operators who base their business at a residential address in Santa Fe are licensed through the City of Santa Fe business license process (Land Use Department), which includes zoning review of the home-based use - there is no separate stand-alone home occupation permit. The city fee schedule includes a home-occupancy business inspection fee. Zoning limits on home-based businesses (customer visits, signage, outdoor storage) apply; confirm specifics with the Business License Office.
