No. 36735 (New Rule): Rule R307-353. Plastic Part Coatings  

  • (New Rule)

    RULE ANALYSIS

    Purpose of the rule or reason for the change:

    In 2006, EPA tightened the 24-hour PM2.5 national ambient air quality standard from 65 to 35 micrograms per cubic meter. Currently, seven Utah counties have been found by EPA to not meet this standard. Automobile, truck, and business machine plastic part coating line operations emit volatile organic compounds (VOCs), which are precursors to the formation of PM2.5. This rule for the PM2.5 State Implementation Plan will lower VOCs that are emitted from from these coating operations.

    Summary of the rule or change:

    This rule applies to automobile, truck, and business machine plastic part coating line operations that have the potential to emit 2.7 tons of volatile organic compounds (VOC) per year and that are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties. The rule establishes reasonably available control technology requirements to reduce VOC emissions. Owners and operators have the option to reduce VOCs by applying coatings with the VOC limits established in the rule or to use add-on controls to achieve at least a 90% VOC reduction. During the public comment period, the Air Quality Board is requesting public input on the appropriateness of applying this rule in Tooele and Box Elder counties.

    State statutory or constitutional authorization for this rule:

    Anticipated cost or savings to:

    the state budget:

    This rule may add to the Division of Air Quality's administrative costs; however, those costs will be minimal. Therefore, there are no anticipated costs or savings to the state budget.

    local governments:

    This rule does not create any new requirements for local government; therefore, there are no anticipated costs or savings to local government.

    small businesses:

    Anticipated cost to sources is $2,020 per ton VOC removed.

    persons other than small businesses, businesses, or local governmental entities:

    This rule applies to coating operations of in the manufacturing or reconditioning of metal cans, drums, pails, and lids that have the potential to emit 2.7 tons of volatile organic compounds (VOC) per year. There are no anticipated costs or savings to persons other than small businesses, businesses, or local government entities.

    Compliance costs for affected persons:

    The compliance cost to implement the requirements of this rule is approximately $2,020 per ton VOC removed.

    Comments by the department head on the fiscal impact the rule may have on businesses:

    The cost to business to comply with this rule is approximately $2,020 per ton VOC removed.

    R307-353-1. Purpose.

    The purpose of this rule is to limit volatile organic compound (VOC) emissions from automobile, truck, and business machine plastic part coating lines.

     

    R307-353-2. Applicability.

    R307-353 applies to automobile, truck, and business machine plastic part coating line operations, including related cleaning activities, that have the potential to emit 2.7 tons per year of VOCs and that are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties.

     

    R307-353-3. Exemptions.

    (1) The provisions of this rule shall not apply to any of the following:

    (a) Stencil coatings;

    (b) Safety-indicating coatings;

    (c) Electric-insulating and thermal-conducting coatings;

    (d) Magnetic data storage disk coatings;

    (e) Plastic extruded onto metal parts to form a coating;

    (f) Touch-up coatings;

    (g) Repair coatings; and

    (h) Textured finishes.

    (2) If a coating line is subject to the requirements for existing automobile, light-duty truck, and other product and material coatings or for existing metallic surface coating lines, the coating line shall be exempt from this rule.

     

    R307-353-4. Definitions.

    The following additional definitions apply to R307-350:

    "Air dried coating" means coatings that are dried by the use of air or a forced warm air at temperatures up to 194 degrees Fahrenheit.

    "Baked coating" means coatings that are cured at a temperature at or above 194 degrees Fahrenheit.

    "Coating" means a protective, functional, or decorative film applied in a thin layer to a surface. This term often applies to paints such as lacquers or enamels. It is also used to refer to films applied to paper, plastics, or foil.

    "Electric-insulating and thermal-conducting" means a coating that displays an electrical insulation of at least 1000 volts DC per mil on a flat test plate and an average thermal conductivity of at least 0.27 BTU per hour-foot-degree-Fahrenheit.

    "Magnetic data storage disk coating" means a coating used on a metal disk which stores data magnetically.

    "Primer" means a coating applied to a surface to provide a firm bond between the substrate and subsequent coats.

    "Repair coating" means a coating used to recoat portions of a part or product which has sustained mechanical damage to the coating.

    "Safety-indicating coating" means a coating which changes physical characteristics, such as color, to indicate unsafe condition.

    "Stencil coating" means an ink or a coating which is rolled or brushed onto a template or stamp in order to add identifying letters or numbers to metal parts and products.

    "Textured finish" means a rough surface produced by spraying and splattering large drops of coating onto a previously applied coating. The coatings used to form the appearance of the textured finish are referred to as textured coatings.

    "Touch-up coating" means a coating used to cover minor coating imperfections appearing after the main coating operation.

    "Topcoat" means the last film-building finishing material applied in a finishing system. Non-permanent final finishes are not topcoats.

     

    R307-353-5. Emission Standards.

    (1) For automobile and truck plastic parts coating lines:

    (a) Each owner or operator shall not apply coatings with a VOC content in excess of the amounts specified in Table 1 or shall use an add-on control device as specified in R307-353-7.

    (b) Except as provided for in R307-353-3, any coating that is subject to an emission rate specified in Table 1 shall not be applied with conventional air-atomizing spray equipment. All spray equipment shall be installed, maintained, and operated in accordance with the recommendations and design of the equipment manufacturer.

    (c) For red and black coatings, the emission limitation shall be determined by multiplying the appropriate limit in Table 1 by 1.15.

    (d) When Method 24 is used to determine the VOC content of a high bake coating, the applicable emission limitation shall be determined by adding 0.5 to the appropriate limit in Table 1.

    (e) When Method 24 is used to determine the VOC content of an air-dried coating, the applicable emission limitation shall be determined by adding 0.1 to the appropriate limit in Table 1.
