(a) Applicability. This section applies to indoor and outdoor spray-coating operations ((at facilities subject to Article 5 (Registration) or Article 7 (Operating Permits) of this regulation, where)) when a coating that protects or beautifies a surface is applied with spray-coating equipment, except as exempted in Section 9.16(b) of this regulation. Mobile spray-coating operations for motor vehicles or motor vehicle components are subject to Section 9.16(e) of this regulation.

(b) Exemptions. The following activities are exempt from the provisions of Sections 9.16 (c) and (d) of this regulation. Persons claiming any of the following ((spray-coating)) exemptions shall have the burden of demonstrating compliance with the claimed exemption.

(1) Application of architectural or maintenance coatings to stationary structures (e.g., bridges, water towers, buildings, stationary machinery, or similar structures);

(2) Aerospace coating operations subject to 40 CFR Part 63, Subpart GG. This includes all activities and materials listed in 40 CFR 63.741(f);

(3) Use of high-volume, low-pressure (HVLP) spray guns when:

(A) spray-coating operations do not involve motor vehicles or motor vehicle components;

(B) the gun cup capacity is 8 fluid ounces or less;

(C) the spray gun is used to spray-coat less than 9 square feet per day per facility;

(D) coatings are purchased in containers of 1 quart or less; and

(E) spray-coating is allowed by fire department, fire marshal, or other government agency requirements.

(4) Use of air-brush spray equipment with 0.5 to 2.0 CFM airflow and a maximum cup capacity of 2 fluid ounces;

(5) Use of hand-held aerosol spray cans with a capacity of 1 quart or less; or

(6) Indoor application of automotive undercoating materials using organic solvents having a flash point in excess of 100F.

(c) General Requirements for Indoor Spray-Coating Operations. It shall be unlawful for any person subject to the provisions of this section to cause or allow spray-coating inside a structure, or spray-coating of any motor vehicles or motor vehicle components, unless all of the following requirements are met:

(1) ((the s)) Spray-coating is conducted inside an enclosed spray area;((.))

(2) The enclosed spray area ((shall)) employs either properly seated paint arresters, or water-wash curtains with a continuous water curtain to control the overspray; and((.))

(3) All emissions from the spray-coating operation ((shall be)) are vented to the atmosphere through an unobstructed vertical exhaust vent.

(d) General Requirements for Outdoor Spray-Coating Operations. It shall be unlawful for any person subject to the provisions of this section to cause or allow spray-coating outside an enclosed structure unless reasonable precautions are employed to minimize the overspray. Reasonable precautions include, but are not limited to the use of:

(1) Enclosures and curtailment during high winds; and

(2) High-volume low-pressure (HVLP), low-volume low-pressure (LVLP), electrostatic, or air-assisted airless spray equipment. Airless spray equipment may be used where low viscosity and high solid coatings preclude the use of higher-transfer efficiency spray equipment.

(e) General Requirements for Mobile Spray-Coating Operations. It shall be unlawful for any person to cause or allow the spray-coating of any motor vehicle or motor vehicle component outside of a structure required by Section 9.16(c) of this regulation, unless all the following requirements are met:

(1) Conduct all spray-coating in a portable frame-and-fabric shelter consisting of a fabric roof and three fabric sides or similar portable shelter consisting of a roof and three sides.

(A) Disassemble and remove the portable shelter from the site at the end of each day.

(B) Do not conduct mobile spray-coating operations for more than 3 consecutive calendar days at any site and not more than 14 days during any calendar month at the same site.

(2) Do not apply more than 8 ounces of coating to any single vehicle.

(3) Do not apply coating to more than 9 square feet of any single vehicle.

(4) Do not prepare a surface area for spray-coating greater than 9 square feet per any single vehicle. The measured surface area prepared for spray-coating shall include, but is not limited to all areas that are filled, ground, sanded, or inside masking.

(5) Do not apply more than 20 ounces of coatings (base coat and clear coat combined) at one site during any calendar day.

(6) Use only HVLP spray guns or spray equipment with equivalent transfer efficiency (greater than or equal to 65%).

(7) Minimize evaporative emissions by collecting all organic solvents used for cleanup of equipment in a closed-loop or contained system; keeping all containers of paints and organic solvents closed except when materials are being added, mixed, or removed; and storing solvent rags in closed containers.

(8) Post a sign that is visible to the public and shows the name of the company and current telephone contact information for complaints.

(9) Complete the following records for each vehicle when finished with that vehicle:

(A) Customer identification, address where work was performed, date, time, and the name of the person completing the record;
