The purpose of this rule is to limit volatile organic compound (VOC) emissions from fabric and vinyl coating operations.
(1) R307-345 applies to fabric and vinyl coating operations located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties.
(2) Before September 1, 2018, R307-345 applies to fabric and vinyl coating operations that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.
(3) Effective September 1, 2018, R307-345 shall apply to fabric and vinyl coating operations that use a combined 20 gallons or more of coating products and associated solvents per year.
The following additional definitions apply to R307-345:
"As applied" means the VOC and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material.
"Fabric coating" means the coating or saturation of a textile substrate with a knife, roll or rotogravure coater to impart characteristics that are not initially present, such as strength, stability, water or acid repellency, 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.
"Knife coating" 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 to 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 pattern to be applied is etched on the coating roll. The coating material is picked up in these recessed areas and is transferred to the substrate.
"Vinyl coating" means applying a decorative or protective top coat, or printing on vinyl coated fabric or vinyl sheets.
(1) No owner or operator shall apply fabric or vinyl coatings with a VOC content greater than 2.2 pounds of VOC per gallon of coating, minus water and exempt solvents (compounds not classified as VOC as defined in R307-101-2), as applied, unless the owner or operator uses an add-on device as specified in R307-345-6.
(2) Organosol and plastisol coatings shall not be used to bubble emissions from vinyl printing and top coating.
(1) Control techniques and work practices are to be implemented at all times to reduce VOC emissions. Control techniques and work practices include:
(a) Covered containers for solvent wiping cloths;
(b) Collection hoods for areas where solvent is used for cleanup;
(c) Covered mixing tanks; and
(d) Covered hoods and oven routed to add-on control devices, which may include, but are not limited to, after burners, thermal incinerators, catalytic oxidation, 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 efficiency and must be operated in accordance with the manufacturers specifications:
(a) Foam coat;
(b) Flow coat;
(c) Roll coat;
(d) Dip coat;
(e) Die coat;
(e) High-volume, low-pressure (HVLP) spray;
(f) Hand application methods; or
(g) Other application method capable of achieving 65% or greater transfer efficiency, as certified by the manufacturer.
(3) Solvent cleaning operations shall be performed using cleaning materials having a VOC composite vapor pressure no greater than 1 mm Hg at 20 degrees Celsius, unless an add-on control device is used as specified in R307-345-6.
(1) If an add-on control system is used, the owner or operator shall install and maintain the add-on emission control system in accordance with the manufacturer recommendations and maintain 90% or greater capture and control efficiency. The overall capture and control efficiency shall be determined using EPA approved methods, as follows.
(a) The capture efficiency of a VOC emission control system's VOC collection device shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable.
(b) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.
(c) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.
(1) The owner or operator shall maintain records of the following:
(a) Records that demonstrate compliance with R307-345. Records shall include, but are not limited to, inventory and product data sheets of all coatings and solvents subject to R307-345.
(b) If an add-on control device is used, records of key system parameters necessary to ensure compliance with R307-345-6.
(i) Key system parameters shall include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule.
(ii) Key inspection parameters shall be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source.
(2) All records shall be maintained for a minimum of 2 years.
(3) Records shall be made available to the director upon request.
