R307-346-4. Definitions. 

"Air dried coating" means coatings that are dried by 

the use of air or a forced wan11 air at temperatures up to 194 

de!:,'TCCS Fahrenheit. 

"Application area" means the area where the coating 

is applied by spraying. dipping, or flow coating techniques. 

"Baked coating" means a coating that is cured at a 

temperature ut or above 194 degrees Fahrenheit. 

"Coating" means a protective, fu nctional, or 

decorative film applied in a thin layer to a surface. Thi ,; term 

applies to paints, sealants, caulks, inks. adhesives. and 

maskants. 

"Ex treme perfom1ance coatings" means coatings 

designed for harsh exposure or extreme environ mental 

conditions. 

"Maskants'' means a material that protects a metal 

surfo'e during the etching process. 

"Metal fu rniture coating" means the surface waling 

of any furniture mad.: of metal or any metal pa1i that will be 

<tssemblcd 'A>ith other metal, wood fabric, plastic, or glass pans 

to frllm a furniture piece. 

R307-346-5. Emission Standards,

R307-346-6. Work Practices. 

( l) ·me owner or operator shall; 

(a) Store all VOC-containing coatings, thinners, and 

cle<m i ng materials in closed containers; 

(b) MinimiL.c spills of VOC-containing coatings, 

thinners, and cleaning materials; 

(c) Clean up spills immediately: 

{d) Convey any coatings, thinners, and cleaning 

materials in closed containers or pipes; 

(e) Close mixing vessels that contain VOC coatings 

and oilier materials except when specifically in use; and 

(f) Minimize usage of solvents during cleaning of 

storage. mixing, and conveying equipment. 

(2) No person shall apply any coating unless the 

coating application method achieves a demonstrated 65%
