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. Louisiana Secretary of State Business Registration

   A mobile car wash or auto detailing business organized as an LLC, corporation or partnership files its formation documents with the Louisiana Secretary of State's Commercial Division through the geauxBIZ portal. A sole proprietor operating under any name other than the owner's own legal name registers a trade name with the Secretary of State — Louisiana has no parish-clerk DBA filing. An LLC is commonly chosen for liability separation because mobile crews work on customers' property, though the entity does not substitute for liability insurance.

2. Louisiana Stormwater and Wastewater Discharge Compliance (no permit or registration)

   Mobile car wash wastewater carries detergents, surfactants, oils and road grime. Under the Clean Water Act and the Louisiana Water Quality Regulations administered by the Louisiana Department of Environmental Quality's Water Permits Division, that wash water may not be discharged to storm drains, street gutters, ditches or waterways. Contain runoff with a berm or containment mat, recover it with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer inlet with the sewer authority's permission or at a licensed facility. There is no LDEQ registration or permit created specifically for mobile car washing; an LPDES permit is required only if your operation has a discharge that needs one. Solvents and degreasers additionally trigger hazardous-waste storage, labeling and disposal duties.

   Official government source

   No registration or permit fee applies to an ordinary mobile car wash — this is a compliance obligation, not a paid application. Budget instead for containment and recovery equipment and for disposal. LDEQ charges fees only where an LPDES permit or coverage is actually required.·Not applicable — there is nothing to apply for and no waiting period. The prohibition applies continuously from the day you operate. Contact the LDEQ Water Permits Division before you start if you are unsure whether your operation needs LPDES coverage.

3. Louisiana Sales Tax Registration

   Louisiana taxes only specifically enumerated services, and car washing/auto detailing is not among them. Register as a dealer with the Louisiana Department of Revenue only if you also sell, lease or rent tangible personal property or digital products — for example retail car-care products (R.S. 47:301(4)). Local sales tax may still apply to goods you sell; confirm with LDR and your local collector.

1. City of Shreveport Occupational License Tax (business license)

   A mobile car wash or auto detailing business operating in Shreveport must hold a city occupational license, administered by the Finance Department's Revenue Division (318-673-5500). One city license covers mobile work throughout Shreveport. A Certificate of Occupancy must be obtained from the Shreveport-Caddo Metropolitan Planning Commission before you apply for the occupational license — including for a home-based operation, which is charged at the lower home-based rate. The city issues a temporary license for the first 30 days of operation and then a permanent license once you update your figures. Renewed annually. If you sell any taxable goods, register separately with the Caddo-Shreveport Sales and Use Tax Commission and the Louisiana Department of Revenue.

   Official government source

The annual tax is then based on gross receipts by classification: retailers on a $50-$6,200 scale, wholesalers on a $50-$7,500 scale, professionals at one-tenth of one percent of gross. Add the Certificate of Occupancy: $75 home-based, $125 for a commercial location, no fee outside city limits.·No processing time is published. The city issues a temporary license covering the first 30 days of operation, then a permanent license. Annual tax notices are mailed in December or January and are due before March 1.

2. Stormwater Discharge Compliance (general prohibition — no city permit)

   Mobile car wash wastewater — which carries detergents, oils and road grime — may not be discharged to storm drains, gutters or waterways. Contain runoff with a portable berm or mat, recover it with a wet/dry vacuum or pump, and dispose of it at an approved sanitary sewer access point or licensed facility. No dedicated Shreveport permit, registration or inspection program for mobile car washes was found; the city's Engineering Permits page covers drainage and right-of-way facility permits, not discharge compliance. State water-quality permitting is handled by the Louisiana Department of Environmental Quality's Water Permits Division.

3. Chemical Handling and Wastewater Compliance (no Caddo Parish registration exists)

   There is no Caddo Parish 'Environmental Health chemical use registration' program. Mobile detailing operations using cleaning agents, degreasers or solvents must comply with OSHA hazard-communication rules (a Safety Data Sheet for each chemical, proper labeling, storage and disposal) and must not discharge wash water or solvents to storm drains; state water-quality permitting is administered by the Louisiana Department of Environmental Quality's Water Permits Division.

4. Certificate of Occupancy (Home-Based Business)

   Shreveport has no separate 'Home Occupation Permit.' A mobile car wash operator storing the vehicle, equipment and supplies at a residential address inside the city must obtain a Certificate of Occupancy for a home-based business from the Shreveport-Caddo Metropolitan Planning Commission (Zoning/Permits Center, 505 Travis St. Ste. 130, 318-673-6480) BEFORE applying for the occupational license. Restrictions include no exterior signage and no on-site customer/employee traffic; bulk chemical storage may trigger separate rules.
