R307-349-I. Purpose. 

TI1e purpose of R307-349 is to limit volatile organic 

compound (VOCi emissions from flat wood panding coating 

sources. 

R307-349-2. Applicability. 

(I) R307-349 applies to sources locnted in Cache. 

Davis, Sall Lake. Utah and \Vebcr counties that have the 

potential to emit 2. 7 tons per year or more of VOC. including 

relatt•d cleaning activities. 

(2) In Box Elder and Tooele counties. R307-349 

apples to the following sources: 

(a) Existing sources as ofFebrum)' I, 2013 with the 

potential to emit 5 tons per year or more of voe. including 

related cleaning activities: and 

( b) New sources as of February L 20 IJ thnt have the

"Coating" means a pmtcctivc. decorative, or 

functional material applied in a thin layer to a surface. Such 

materials may include paints, topcoats, varnishes. sealers. 

stains, washcoaL~. basecoals. inks. and temporary protective 

coatings. 

"Finishing material" means a coating used in the flat 

wood panel industry. including basecoats. stains, washcoats. 

scalers, and topcoats. 

"Flat wood paneling" means wood paneling products 

that are any decorative interior. exterior or tileboard (class I 

hardboard) panel to whid1 a protective. decoraiivc. or 

functional material or layer has been applied. 

"Sealer" me;ms a finishing material used to seal the 

pores of a wood substrate before additional coats of finishing 

material arc applied. A washcoat used to optimize ac,1hetics is 

not a scaler. 

"Strippablc booth coating" means a coaling that is 

applied to a booth wall to provide a protceti c film 10 receive 

ovcrspray during finishi ng and that is subsequently peeled and 

disposed. Strippable booth coatings are intended to reduce or 

eliminate the need to use organic solvents to clean booth walls. 

"Tilcboard'' means u premium interior wall paneling 

product made of hardboard that meets the specifications for 

Class I given by the standard ANSI/AHA i\ 135.4-1995.
