(d) A miscellaneous plastic parts coating and pleasure craft coating operation applicable to this rule can choose to use an equivalent volatile organic compound emission rate limit based on the use of a combination of low-volatile organic compound coatings specified in table 68 to table 68-c, specified methods of application specified under subdivision (b) of this subrule, and add-on controls. The overall emission reduction efficiency needed to demonstrate compliance is determined each day as follows: (i) Obtain the emission limitation from table 68 to table 68-c. If using the pound of volatile organic compound per gallon of coating, excluding water, as applied limit from table 68 or table 68-b, then calculate the emission limitation in a solids basis according to the following equation: S = C / [1 - (C/7.36 lb/gal)]
Where:
S = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating solids.
C = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating, (excluding water) as applied.
(ii) Calculate the required overall emission reduction efficiency of the control system for the day according to the following equation: E = [(VOCa - S)/VOCa] x 100
Where:
E = The required overall emission reduction efficiency of the control system for the day.
VOCa = The maximum VOC content of the coatings, as applied, used each day on the subject coating line, in units of lb VOC/gal coating solids, as determined by the applicable test methods and procedures specified in subdivision (h) of this subrule.
S = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating solids.
(e) Should product performance requirements or other needs dictate the use of higher-volatile organic compound materials than those that would meet the recommended emission limits, a facility can choose to use add-on control equipment that must have an overall control efficiency of 90% or higher instead of using low-volatile organic compound coatings and specified application methods.(f) For each coating line, compliance with the emission limits specified in this rule is based upon all of the following: (i) 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.(ii) 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.(iii) The information and records as required by subrule (6) of this rule.(g) Compliance with the emission limits specified in subrule (4) of this rule, must be determined using 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.(5) The following work practices are required for storage, mixing operations, and handling operations for coatings, thinners, cleaning, and coating-related waste materials. The person responsible for a miscellaneous plastic parts coating and pleasure craft coating operation shall develop written procedures for compliance with the following provisions: (a) Store all volatile organic compound-containing coatings, thinners, coating-related waste, and cleaning materials in closed containers.(b) Ensure that mixing and storage containers used for volatile organic compound-containing coatings, thinners, coating-related waste, and cleaning materials are kept closed at all times, except when depositing or removing these materials.(c) Minimize spills of volatile organic compound-containing coatings, thinners, coating-related waste, and cleaning materials.(d) Convey volatile organic compound-containing coatings, thinners, coating-related waste, and cleaning materials from 1 location to another in closed containers or pipes.(e) Minimize volatile organic compound emissions from cleaning of application, storage, mixing, and conveying equipment by ensuring that equipment cleaning is performed without atomizing the cleaning solvent and all spent solvent is captured in closed containers.(6) 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 the determination of compliance with the provisions of this rule, as required in R 336.2041.Mich.
