R307-345. Fabric and Vinyl Coatings. 

R.307-345- 1. Purpose. 

Ilic puq)OSC of th is rnlc is to limit volatile organic 

compound {VOC) emissions from fobric and vinyl coming 

operations, which usc roll. knife. or rotogravure coaters and 

drying ovens. 

R307-345-2. Applicability. 

(I) RJ07-345 applies to sources located in Cache, 

Davis, Salt Lake, Utah and Weber counties that have the 

potential to emit 2.7 tons per year or more of voe, including 

related cleuning activities. 

(2) In Box Elder and Tooele counties, R307-345 

applies to the following sources: 

(a) Existing sources as of Febnmy I. 2013 with the 

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

related cleaning activities; and 

(b) New sources as of February J. 2013 that have the 

potential ro emit 2.7 tons per year or more of voe, including 

related cleaning activities. 

R307-345-3. Definitions. 

Tl1c following additi.onal definitions apply lo IU07-

345: 

"Coating" mem1s a protective, functional, or 

decorative film applied in a thin layer ro a surface. 

"Fabric coating" means the coating or saturation of a 

textile substrate with a knife, roll or rotogravure coater to 

impart characteristics that arc not initially present. such as 

strength., stability, water or acid repeilency. or appearance. 

Fabric coatings can include, but are not limited to . industrial 

and electrical tapes. tie cord, utility meter seals, imitation 

leathers, tarpaulins. shoe material, and upholstery fabrics. 

"Knit\: coati ng" means the application of a coating 

material to a substrate by means of drawing the substrate 

beneath a blade that spreads the coating evenly over the width 

of the substrate. 

"Roller coating" the coating material is applied to the 

moving fabric, in a direction opposite w the movement of the 

substrate, by hard rubber or steel rolls. 

"Rotogravure coating" means the application of a 

uniform layer of material across the entire width of the web to 

substrate by means of a roll coating technique in which the 

puttern to be applied is etched on the coating roll. TI1e coating 

material is picked up in these recessed areas and is transferred 

to !he substrate. 

"Vinyl coatmg" means applying a decorative or 

protective top coat, or printing on vinyl coated fabric or vinyl 

sh eels. 

RJ07-345-4. £mission Standards. 

(I) Each owner or operator shall not apply coating.:< 

with a VOC content in excess of the amounts spccilied in Table 

I or shall use an 11dd-on control device as specified in R307-

345-6.

R307-345-5. Work Practices and Recordkeeping. 

( l) Control techniques and work practices are to be 

implemented at ttll times lo reduce voe emissions from 

f\1gitivc type sources. Control techniques and work practices 

include · 

{a) Tight fitting covers for open tanks or drums; 

(b) Covered containers for sol vent wiping cloths; 

(c) Collection hoods for areas where solvent is used 

for cleanup; 

(d) Covered mixing tanks; and 

(c) Covered hoods and oven routed to add-on 

control devices, which may include, but are not limited to, idler 

burners. thermal incinerators. catalytic oxidatiou, or carbon 

adsorption. 

(2) No person shall apply any coating unless the 

coating application method achieves a demonstrated 65% 

transfer efficiency. 

The following applications achieve a minimum of 

65% transfer dliciency and must be operated in accordance 

\\ ith the manufacturers specifications: 

{a) Foam coat; 

(b) Flow coat; 

(c) Roll coal; 

(d) Dip coat 

(e) Die coat; 

(e) High-volume, low-pressure (HVLP) spray; 

(t) Hand application methods; or 

(g) Other application method capable of achieving at 

least 65% transfer efficiency, as certified by the manufacturer. 

(3) All persons shall perform sol vent cleaning 

operations with d eaning material having voe content of 0.2 1 

pounds per gallon or less. 

(4) All sources subject to R307-345 shall maintain 

records demnnstrnting compliance with all provisions ofR307-

345 on an annual ba-;is. 

{a) Records shall include, but not be limited to, 

invento1y and product data sheets of all coatings and solvents 

subject to IU07-345. 

(b) · fllcsc records shall be available to the director 

upon request. 

R.307-345-6. Optional Add-On Controls. 

( l) The owner or operator may install and maintain 

an 

incinerator. carbon adSO!TJlion. or any other add-on emission 

control device, provided that the emission control device will 

attain al least 90% efficiency performance. 

(2) ·nic owner or operator of a control device shall 

provide documentation that the emission control system will 

attain the requ irements of R307-345-6. 

E - 41
