R 336.1632 Emission of volatile organic compounds from existing automobile, truck, and business machine plastic part coating lines.

Rule 632. (1) A person shall not cause or allow the emission of volatile organic compounds from an automobile, truck, or business machine plastic part coating line in any of the following counties unless all of the provisions of subrules (2) to (14) of this rule are met, as applicable: (a) Western portion of Allegan. (b) Berrien. (c) Kent. (d) Livingston. (e) Macomb. (f) Monroe. (g) Muskegon. (h) Oakland. (i) Ottawa. (j) St. Clair. (k) Washtenaw. (l) Wayne. (2) The following provisions must be met: (a) A person shall not cause or allow the emission of volatile organic compounds from the coating of plastic parts of automobiles and trucks from any existing coating line in excess of the applicable emission rates as specified in table 66. (b) Except as provided for in subrule (10) of this rule, any coating that is subject to an emission rate specified in table 66 must not be applied with conventional air-atomizing spray equipment. All spray equipment must be installed, maintained, and operated in accordance with the recommendations and design of the equipment manufacturer. (c) A person shall not cause or allow the emission of volatile organic compounds from the coating of plastic parts of business machines from any existing coating line in excess of the applicable emission rates as specified in table 67. (d) Except as provided for in subrule (10) of this rule, any prime or topcoat coating that is subject to the emission rate specified in table 67 must not be applied with air-atomizing spray equipment. All spray equipment must be installed, maintained, and operated in accordance with the recommendations and design of the equipment manufacturer. (3) If a part consists of both plastic and metal surfaces and is exempted from the provisions of R 336.1621 or R 336.1621a based on the provisions of R 336.1621(9)(e) and R 336.1621a(2)(b)(ii) respectively, the part is subject to this rule. (4) If a coating line is subject to the provisions of R 336.1610, R 336.1610a, R 336.1621, or R 336.1621a, the coating line is exempt from this rule. (5) A person that is responsible for the operation of a coating line that is subject to this rule shall obtain current information and maintain daily records necessary for a determination of compliance with the provisions of this rule, as required in R 336.2041. (6) For each coating line, compliance with the emission limits specified in this rule is based upon all of the following: (a) The volume-weighted average of all coatings that belong to the same coating category and are used during each calendar day averaging period. The department may specifically authorize compliance, under R 336.1602(2), to be based upon a longer averaging period, not to exceed more than 1 calendar month. (b) If coatings belonging to more than 1 coating category are used on the same coating line during the specified averaging period, then compliance must be determined separately for each coating category. (c) The information and records as required by subrule (5) of this rule. (7) Compliance with the emission limits specified in subrule (2) of this rule, the method described in either R 336.2040(12)(a) if the coating line does not have an add-on emissions control device or R 336.2040(12)(b) if the coating line has 1 or more add-on emissions control devices. (8) A modification of coating applicator equipment for the primary purpose of achieving compliance with subrules (2)(b) and (d) of this rule, to the extent that the modification does not increase the potential to emit, must not be subject to the provisions of R 336.1220 and R 336.1702. (9) The provisions of this rule, with the exception of the provisions of subrule (5) of this rule, do not apply to any of the following: (a) Automobile, truck, or business machine plastic part coating lines which are within a stationary source located within the 2015 ozone nonattainment areas and have a combined actual emission rate of volatile organic compounds of less than or equal to 15 pounds per calendar day. (b) Automobile, truck, or business machine plastic coating lines within any stationary source located in Ottawa, the eastern portion of Muskegon as defined in R 336.1601, or Kent Counties and that have a total combined emission rate of volatile organic compounds from plastic coating lines of less than 30 tons per calendar year. The total combined emission rate must include emissions from coatings and coating operations exempted from this rule. If the total combined emissions equal or exceed 30 tons in any subsequent year, the provisions of this rule permanently applies to these plastic coating lines for as long as the applicable equipment is in operation. (c) The application of adhesion primes. (d) The application of electrostatic prep coats. (e) The application of resist coats. (f) The application of stencil coats. (g) The application of texture coats to automobile or truck parts. (h) The application of vacuum metalizing coatings. (i) The application of gloss reducer. (j) An automobile, truck, or business machine plastic part coating operation located in Ottawa, the eastern portion of Muskegon, or Kent Counties consisting of an applicator and any subsequent flash-off area or oven, or both, from which the total emission rate of volatile organic compounds is equal to or less than 2,000 pounds per calendar month and 10.0 tons per calendar year. The total combined emission rate of volatile organic compounds from these exempted operations at a stationary source must not be more than 30.0 tons per calendar year. If the total emission rate for an operation is more than 2,000 pounds in any subsequent month or 10 tons per year in a subsequent year, the provisions of this rule permanently apply to these automobile, truck, or business machine plastic part coating operations for as long as the applicable equipment is in operation. (k) Low-use coatings that total 55 gallons or less per rolling 12-month period at a stationary source. (10) The provisions of subrule (2)(b) and (d) of this rule do not apply to the equipment used in any of the following: (a) The application of the final coat of metallic topcoat. (b) The application of waterborne coatings. (c) The application of touch-up and repair coatings. (d) Coating operations controlled by add-on emission controls. (e) Coating operations for which an acceptable demonstration has been made that conventional air-atomizing spray equipment is the only technically feasible application method. (f) Other coating operations that together account for a total of 20% or less of the total volume of coatings applied by nonexempt coating application equipment calculated on a calendar day basis. (11) A person may discontinue the operation of a natural gas-fired afterburner, that is used to achieve compliance with the emission limits in this rule, between November 1 and March 31 unless the afterburner is used to achieve compliance with, or is required by, any of the following: (a) Another provision of these rules. (b) A permit to install. (c) A permit to operate. (d) A voluntary agreement. (e) A performance contract. (f) A stipulation. (g) An order of the department. (12) If the operation of a natural gas-fired afterburner is discontinued between November 1 and March 31 pursuant to the provisions of subrule (11) of this rule, then both of the following provisions apply during this time period: (a) All other provisions of this rule, except for the emission limits, remain in effect. (b) All other measures that are used to comply with the emission limits in this rule between April 1 and October 31 must continue to be used.
