Rule 634. (1) As used in this rule, “composite partial vapor pressure” means the sum of the partial pressures of the VOC compounds in a solvent. (2) A person shall not cause or allow the emission of any volatile organic compound from the use of solvent materials in excess of the limitations of this rule in solvent cleaning operations, which are described as follows: (a) Released during the production, repair, maintenance, or servicing of parts, products, tools, machinery, equipment or in general work areas including storage or disposal of these solvent materials. (b) Located in the 2015 ozone nonattainment area. (3) With the exception of subrule (6) of this rule, the provisions of this rule do not apply to the following activities: (a) Janitorial cleaning. (b) Stripping of cured coatings, cured ink, or cured adhesives. (c) Cleaning operations in printing pre-press or graphic areas including lithographic, letterpress, flexographic, screen printing, and rotogravure printing operations. (d) Cleaning operations associated with digital printing. (e) Cleaning operations for which limits or work practice standards are contained within R 336.1610, R 336.1610a, R 336.1620, R 336.1620a, R 336.1621, R 336.1621a, R 336.1624, R 336.1624a, R 336.1632, R 336.1633, R 336.1635, R 336.1636, R 336.1637, R 336.1638, and R 336.1639. (f) Cleaning operations at a facility with emissions less than 3 tons per rolling 12-month period for all cleaning activity, before consideration of controls. If the combined actual emission rate equals or is more than 3 tons per year on a 12-month rolling basis before consideration of controls, as determined in a subsequent month, then this rule permanently applies to the cleaning operations at that facility.

(v) Non-atomized solvent flow method where the cleaning solvent is collected in a container or a collection system that is closed except for solvent collection openings and, if necessary, openings to avoid excessive pressure build-up inside the container. (vi) Solvent flushing method where the cleaning solvent is discharged into a container that is closed except for solvent collection openings and, if necessary, openings to avoid excessive pressure build-up inside the container. The discharged solvent from the equipment must be collected into containers without atomizing into the open air. (c) Instead of complying with subdivisions (a) and (b) of this subrule for a solvent cleaning operation, a person that is subject to this rule may comply by installing and operating volatile organic compound emission control equipment for the solvent cleaning operation. The volatile organic compound emission control equipment must have an overall control efficiency of 85%. (d) Instead of complying with subdivisions (a) and (b) of this subrule, a manufacturer of coatings, inks, resins, or adhesives may comply with subdivision (e) of this subrule or the following: (i) Clean portable tables or stationary mixing vats, high dispersion mills, grinding mills, tote tanks, and roller mills by 1 or more of the following methods: (A) Use a cleaning solvent that either contains less than 1.67 pounds per gallon of volatile organic compound or has a composite vapor pressure no more than 8 mm of Hg at 20 degrees Celsius. (B) Comply with the following work practices: (1) Equipment being cleaned must be maintained leak free. (2) Volatile organic compound-containing cleaning materials must be drained from the cleaned equipment upon completion of cleaning.

(iii) The volume, in gallons, of each solvent employed in the solvent cleaning operation. (iv) The total volume, in gallons, of all the solvents employed in the solvent cleaning operation. (b) If a person operating a solvent cleaning operation employs a control device to achieve and maintain compliance, that person shall create and submit an approvable preventative maintenance and monitoring plan to the department which includes details about all appropriate parameters to be monitored and recordkeeping sufficient to determine compliance.
