Section R. 336.1610 - Existing coating lines; emission of volatile organic compounds from existing automobile, light-duty truck, and other product and material coating lines

Rule 610.

(1) A person shall not cause or allow the emission of volatile organic compounds from the coating of automobiles and light-duty trucks, from any existing coating line, in excess of the applicable emission rates shown in table 62.
(2) A person shall not cause or allow the emission of volatile organic compounds from the coating of any of the following, from an existing coating line, in excess of the applicable emission rates shown in column A of table 63 or the equivalent emission rates in column B of table 63:
(a) Cans.
(b) Coils.
(c) Large appliances.
(d) Metal furniture.
(e) Magnet wire.
(f) The nonmetallic surfaces of fabrics, vinyl, or paper.
(3) Subrule (2) of this rule notwithstanding, and as an alternative to the allowable emission rate established by table 63, the existing paper coating lines at Fletcher Paper Company of Alpena may comply with subrule (2) of this rule by not exceeding a volatile organic compound emission rate of 180 tons per calendar year and 30 tons per calendar month.
(4) A person who is responsible for the operation of a coating line that is subject to this rule shall obtain current information and keep records necessary for the determination of compliance with this rule, as required in R 336.2041.
(5) For each coating line, compliance with the emission limits specified in table 62 and table 63 must be based upon all of the following provisions:
(a) For prime coat operations that utilize an electrodeposition process in automobile and light-duty truck coating lines that are regulated under table 62, compliance must be based upon all coatings that belong to the same coating category that is used during each calendar month averaging period. For all other coatings, compliance must be based upon 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 to be based upon a longer averaging period, which must not be more than 1 calendar month.
(b) If coatings that belong 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 (4) of this rule.
(6) Compliance with the emission limits specified in this rule must be determined using 1 of the following methods, as applicable:
(a) For the prime-electrodeposition process and for the final repair emission limits specified in table 62, 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.
(b) For the primer surfacer and topcoat emission limits specified in table 62, compliance must be determined by the methodology described in the publication entitled "Protocol for Determining the Daily Volatile Organic Compound Emission Rate of Automobile and Light-duty Truck Topcoat Operations", EPA-453/R-08-002, adopted by reference in R 336.1902. References to topcoat operations in this publication also apply to primer surfacer lines, with the following added provisions:
(i) Unless specifically included in the adopted publication, if an anti-chip, color-in-prime, blackout, or spot primer coating is applied as part of either a primer surfacer or topcoat coating operation, then the anti-chip, color-in-prime, blackout, or spot primer coating must be included in the transfer efficiency tests for that coating operation, conducted according to section 18 or 19 of the adopted publication, and the transfer efficiency values in section 20 of the adopted publication must not be used.
(ii) If spot primer is applied as part of a primer surfacer coating operation, then the daily usage of spot primer, as calculated in section 8 of the adopted publication, may be derived from monthly usage of spot primer based upon the number of vehicles processed in the primer surfacer operation each day. If an add-on emissions control device is used on the coating line application area to achieve compliance with the primer surfacer or topcoat emission limits specified in table 62, then the capture efficiency must be determined in accordance with R 336.2040(10).
(c) For the emission limits specified in column B of table 63, the method described in either R 336.2040(12)(e) if the coating line does not have an add-on emissions control device or R 336.2040(12)(f) if the coating line has 1 or more add-on emissions control devices.
(d) For the emission limits specified in column A of table 63, 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.
(7) The provisions of this rule, except for the provisions in subrule (4) of this rule, do not apply to coating lines that are within a stationary source and that have a combined actual emission rate of volatile organic compounds of less than 100 pounds per day or 2,000 pounds per month as of November 4, 1999. If the combined actual emission rate equals or is more than 100 pounds per day for a subsequent day or 2,000 pounds per month for a subsequent month, then this rule permanently applies to the coating lines.
(8) A person may exclude low-use coatings that total 55 gallons or less per rolling 12-month period at a stationary source from the provisions of this rule, except for subrule (4) of this rule.
(9) Between November 1 and March 31, 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, 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.
(10) If the operation of a natural gas-fired afterburner is discontinued between November 1 and March 31 under subrule (9) of this rule, then both of the following provisions apply between November 1 and March 31:
(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.
(11) Tables 62 and 63 read as follows:
