for the vessels is responsible for certifying that the intended use is for recreational purposes.
(b) “Pleasure craft surface coating” means any marine coating, except unsaturated polyester resin
(fiberglass) coatings, applied by brush, spray, roller, or other means to a pleasure craft.
(2) A person shall not cause or allow the emission of any volatile organic compound from the
surface coating of miscellaneous plastic parts and products, or pleasure craft coatings in excess of
the limitations of this rule in miscellaneous plastic parts and products operations or pleasure craft
operations from any existing source located within the 2015 ozone nonattainment area, in excess
of the applicable emission rates provided in subrule (4) of this rule.
(3) The provisions of this rule do not apply to the following:

emission rate of volatile organic compounds, including related cleaning activities, of less than 15
pounds per day before consideration of controls. If the combined actual emission rate equals or is
more than 15 pounds per day for a subsequent day, then this rule permanently applies to these
coating lines.

(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.
