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. Mississippi Business Registration (Secretary of State)

   Mobile car wash and auto detailing businesses operating in Mississippi as an LLC, corporation, or limited partnership must register with the Mississippi Secretary of State. Sole proprietors using a trade name file a Fictitious Business Name Registration with the Secretary of State (Mississippi has no county-level DBA registry). An LLC is commonly chosen to protect personal assets, since mobile operations work on customers' property.

2. Mississippi Stormwater and Wash Water Discharge Compliance

   Mobile car wash wastewater carries detergents, surfactants, oils, and road grime. Mississippi rules, consistent with the federal Clean Water Act, prohibit discharging it to storm drains, street gutters, or waterways. Operators must contain the wash water with a berm or mat and recover it with a wet/dry vacuum or pump, or direct it to a sanitary sewer inlet with the utility's permission. There is no registration or permit to apply for - MDEQ enforces the prohibition. Using hazardous solvents or degreasers brings additional storage and disposal duties; contact MDEQ for guidance.

3. Mississippi Department of Revenue - Sales Tax Permit (car wash and detailing)

   Car washing - automatic, self-service, or manual - is expressly taxable under Miss. Code Ann. Section 27-65-23 at 7% of gross income, so a car wash or auto detailing business must register with the Mississippi Department of Revenue for a sales tax permit, collect the tax from customers, keep records of all transactions, and remit on the schedule the Department assigns.

2. City of Gulfport Stormwater Illicit Discharge Compliance

   Gulfport's Stormwater Management Plan (Public Works) enforces Ordinance No. 2896, the Illicit Discharge Detection and Elimination ordinance, and names illegal dumping and improper disposal of automobile wastes as a target of the program. Mobile car wash wastewater carrying detergents, oils and road grime must not reach storm drains, gutters or waterways. There is no permit or registration for mobile car wash operators to apply for; instead, contain runoff with a berm or mat, recover the wash water with a wet vacuum or pump, and dispose of it through an approved sanitary sewer connection or a licensed disposal facility. Report illicit discharges to Stormwater Management (228-868-5740 ext. 6619) or the 311 call center; violations of the ordinance are enforced against the discharger.

3. Chemical handling for mobile detailing — OSHA Safety Data Sheets, no county registration

   Harrison County has no Environmental Health department and no chemical-use registration for mobile detailing businesses; county health services run through MSDH's county health offices and environmental/hazardous-materials matters through MDEQ, neither of which registers routine detailing chemicals. Keeping a Safety Data Sheet for each cleaning agent, degreaser or solvent is a federal OSHA Hazard Communication Standard duty owed to employees, not a county filing. If your operation generates hazardous waste in regulated quantities, check MDEQ's hazardous waste generator rules; typical detailing chemical use does not trigger a county registration.

4. City of Gulfport Privilege License + Zoning Compliance for a Home-Based Business

   Mobile car wash operators storing a vehicle, equipment and supplies at a Gulfport residence obtain the standard Privilege License from Urban Development / Building Code Services. Gulfport Planning & Zoning publishes a Planning Commission Approval for Home Occupations application, and the Certificate of Zoning Compliance that accompanies every Privilege License asks whether protective covenants prohibit home occupations at the address. So a home-based business is handled through the Privilege License plus zoning compliance, with Planning Commission approval where the zoning district requires it. Storing chemicals in quantities that trigger fire-code or hazardous-materials handling rules may require additional review — confirm with Building Code Services (228-868-5700).

   No separate home-occupation fee is published. The Privilege License fee is computed from business type and employee count or inventory value — confirm the amount with Building Code Services.·Not published by the City; note that staff approval of the application expires after 60 days if the license is not issued.
