(5)   If a part consists of both plastic and metal surfaces and is exempted from the provisions of R 336.1621 based on the provisions of R 336.1621(9)(e), the part shall be subject to this rule.

(6)   If a coating line is subject to the provisions of R 336.1610 or R 336.1621, the coating line shall be exempt from this rule.

(7)   A person who 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.

(8)   For each coating line, compliance with the emission limits specified in this rule shall be based upon all of the following:

(a)   The date or dates equipment shall be ordered.

(b)   The date or dates construction, modification, or process changes shall begin.

(c)   The date or dates initial start-up of equipment shall begin.

(12)   A modification of coating applicator equipment for the primary purpose of achieving compliance with the provisions of subrules (3)(b) and (4)(b) of this rule, to the extent that such modification does not increase the potential to emit, shall not be subject to the provisions of R 336.1220 and R 336.1702.

(13)   As part of the compliance program required by the provisions of subrule (10) of this rule, a person who is responsible for the operation of a coating line that is subject to this rule may request alternate provisions to those specified in this rule. The commission may establish alternate provisions for a period of time to be specified by the commission if all of the following conditions are met:

(a)    The coating line that is subject to the alternate provisions is in compliance, or on a legally enforceable schedule of compliance, with the other rules of the commission.

(b)      Compliance with the provisions of this rule is not technically or economically reasonable.

(c)    All measures that are both technically feasible and economically reasonable to reduce volatile organic compound emissions as required by this rule have been implemented in accordance with, or will be implemented in accordance with, a schedule approved by the commission. All alternate provisions approved by the commission shall become part of a legally enforceable order or part of an approved permit to install or operate.

(14)   The program for compliance that is required by the provisions of subrule (10) of this rule may address a combination of coating lines that are subject to the provisions of this rule, or 1 or more coating lines that are subject to the provisions of this rule in combination with 1 or more existing sources that are subject to the provisions of other rules of this part, if all of the following conditions are met:

(a)   All of the requirements specified in the United States Environmental Protection Agency's emissions trading policy statement, 51 F.R. 43814, December 4, 1986, are met.
