  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.

State of Maine

3 stops

  1. Maine Business Registration (Secretary of State)

    Mobile car wash and auto detailing businesses operating in Maine register with the Maine Secretary of State's Bureau of Corporations, Elections and Commissions if structured as an LLC, corporation or partnership. An LLC is formed by filing a Certificate of Formation (form MLLC-6). Sole proprietors do not register with the State: a sole proprietor or partnership using a trade name files an assumed-name certificate with the city or town clerk where the business is located, under 31 MRSA section 2. An LLC is commonly chosen for the personal liability protection it provides.

    Official government source

    $175 Certificate of Formation filing fee for an LLC (form MLLC-6); expedited service costs $50 extra for next-business-day or $100 for same-day filing. A sole proprietor pays no state filing fee - the trade name certificate goes to the city or town clerk instead.The Bureau of Corporations, Elections and Commissions currently reports corporate filing processing time of 40-55 business days; expedited filing is available for the added fee

  2. Maine DEP Wastewater / Stormwater Discharge Compliance

    Mobile car wash operations generate wash water containing detergents, surfactants, oils and road grime. Maine Department of Environmental Protection rules, consistent with the federal Clean Water Act, prohibit discharging this wash water to storm drains, street gutters, ditches or waterways. Operators must capture wash water (containment mat or berm plus a wet vacuum or pump) and dispose of it to a sanitary sewer with the local sewer district's permission, or to a licensed disposal facility. The agency is the Department of Environmental Protection - Maine has no 'Department of Environmental Quality'.

    Official government source

    No state permit or fee for a mobile operator that captures and properly disposes of wash water; illegal discharge can bring enforcement penaltiesNo application process - set up containment and a disposal arrangement before operating

  3. Maine Sales Tax Registration (Maine Revenue Services)

    Maine taxes sales of tangible personal property and a short statutory list of services - ancillary and telecommunications services, extended cable and satellite TV, rentals of video and furniture, and fabrication services. Car washing and auto detailing labor is not on that list, so the service itself is not taxable. You still register with Maine Revenue Services for a sales tax account if you sell taxable goods (wax, air fresheners, detailing products) at retail, and you owe use tax on supplies bought untaxed for your own use.

    Official government source

    Free - Maine Revenue Services charges no fee to register for a sales tax accountRegister online through the Maine Tax Portal; the account is normally active immediately

City of Lewiston / Androscoggin County

4 stops

  1. No Lewiston Business License for Mobile Car Wash or Auto Detailing

    Lewiston has no blanket business licence. The City Clerk's Department licenses over 40 specific business types required by Maine statute or city ordinance - adult businesses, bowling alleys, carnivals, flammable liquid storage, flea markets, food service establishments, group care facilities, lodging houses, massage establishments and therapists, mobile units and roving diners, pawnbrokers, peddlers, second-hand dealers, tattoo parlours, taxicab companies and others - and publishes a fee for each in its Business License Applications Fees, Penalties and Inspection and Approval Schedule. Mobile car wash and auto detailing are not on that list, and Androscoggin County licenses no businesses at all.

    Official government source

    No fee - mobile car wash and auto detailing are not among Lewiston's licensed business categoriesNo application process; confirm with the City Clerk's Department at 207-513-3124 if you are unsure whether your services fall into a licensed category

  2. Lewiston Stormwater / Wash-Water Discharge Compliance

    Lewiston runs a municipal separate storm sewer system (MS4) programme under a Maine DEP permit and a five-year Stormwater Management Plan; stormwater drains untreated to the Androscoggin River and local ponds, so the City's ordinance prohibits discharging pollutants to storm drains. A mobile car wash must contain its wash water - detergents, oils and road grime - with a berm or mat, recover it with a wet/dry vacuum or pump, and dispose of it to the sanitary sewer with the Water and Sewer Division's approval or to a licensed facility. Lewiston issues no mobile car wash discharge permit, and Androscoggin County has no environmental health function.

    Official government source

    No permit or registration fee - Lewiston issues no stormwater discharge permit for mobile car washing; illicit discharge can bring enforcement actionNo application process; arrange containment and a disposal route before operating. Contact Public Works at 207-513-3003 about sanitary sewer disposal.

  3. Hazardous Chemical Handling Compliance (OSHA and Maine DEP)

    Mobile detailing operations that use chemical cleaning agents, engine degreasers or solvents must keep a Safety Data Sheet for each product under the federal OSHA Hazard Communication Standard, and must store and dispose of hazardous materials and wash water under Maine Department of Environmental Protection rules. There is no Androscoggin County Environmental Health department and no county chemical-use registration in Maine - counties here run no environmental health programmes. Wash water containing detergents and solvents must also be kept out of Lewiston's storm drains under the City's MS4 stormwater ordinance.

    Official government source

    No fee - there is no county chemical-use registration in Maine, and Maine DEP charges small-quantity generators no registration feeNo application process; keep Safety Data Sheets on hand and arrange proper disposal before operating

  4. Lewiston Home Occupation Permit (if operating from a residence)

    A mobile car wash operator who stores the vehicle, equipment and supplies at a Lewiston residence needs a Home Occupation permit from the Planning and Code Enforcement Department. Lewiston's Planning and Code Enforcement Department issues Home Occupation permits, and its published application sets the qualifying tests: the occupation employs only residents of the premises, uses less than 25 percent of the total floor area, produces no change in the outside appearance beyond one sign, generates no more traffic than the neighbourhood would normally see, provides off-street parking, creates no noise, vibration, glare, fumes or odours detectable off the lot, keeps no stock in trade on the premises, and is not one of the excluded uses (nursing home, tourist home, family daycare, animal hospital, restaurant, doctor's or dentist's office, real estate office, registered caregiver, beauty shop or barbershop, apart from a one-chair appointment-only owner-occupied barbershop). A floor plan of the dwelling showing the area used must accompany the application. Storing detergents and chemicals on site and parking a commercial vehicle are the questions to settle with Code Enforcement before relying on the permit.

    Official government source

    No fee is printed on the City's Home Occupation Application; Planning and Code Enforcement quotes the amount when the application is reviewed - confirm at 207-513-3125Submit the application with a floor plan to Planning and Code Enforcement; staff quote any fee, and review begins on payment
