Current through Register Vol. 46, No. 28, July 10, 2024
(a) Use
					 of coatings that exceed the VOC content limits at application specified in the
					 tables of section
					 228-1.4 
					 of this Subpart is prohibited, unless a coating system meeting the requirements
					 of subdivision (d) of this section is utilized, control equipment meeting the
					 requirements of subdivisions (b) and (c) of this section is installed and
					 operated, or a process specific RACT variance is granted under subdivision (e)
					 of this section.
(b) Any VOC
					 incinerator used as control equipment must be designed and operated to provide,
					 at a minimum a 90 percent overall removal efficiency. The department may allow
					 an owner or operator of a facility which uses a natural gas fired VOC
					 incinerator as a control device for coating lines subject to this Subpart to
					 shut down the VOC incinerator from November 1st through March 31st for the
					 purposes of natural gas conservation, provided that the department has
					 determined that this action will not jeopardize air quality.
(c) The overall removal efficiency of an air
					 cleaning device used as a control strategy must be determined, for every
					 surface coating formulation, on a solids as applied basis using Equation 2
					 unless a 90 percent or greater overall removal efficiency is achieved by the
					 air cleaning device. The air cleaning device must be designed and operated to
					 provide, at a minimum, an overall removal efficiency of either 90 percent or as
					 determined by Equation 2.
Equation 2

where:
is the overall removal efficiency
(VOC)c is the maximum permissible
						pounds of VOC per gallon of coating minus water and excluded VOC at
						application, as set forth in the tables of this Subpart.
(VOC)a is the VOC content of an
						as applied coating, expressed as pounds of VOC per gallon of coating minus
						water and excluded compounds.
(Vn)c is
						the volumetric fraction of solids, expressed as gallon of solids per gallon of
						coating minus water and excluded compounds, in a compliant coating expressed
						as:
Equation 3
(Vn)c = 1 -
						(Vv)c
(Vv)c is
						the volumetric fraction of VOC, expressed as gallon of VOC per gallon of
						coating minus water and excluded compounds, in a compliant coating expressed
						as:
Equation 4

(Vn)a is
						the volumetric fraction of solids, expressed as gallon of solids per gallon of
						coating minus water and excluded compounds, in an as applied coating expressed
						as:
Equation 5
(Vn)a = 1 -
						(Vv)a
(Vv)a is
						the volumetric fraction of VOC, expressed as gallon of VOC per gallon of
						coating minus water and excluded compounds, in an as applied coating expressed
						as:
Equation 6

dvoc is the density of VOC as
						applied, i.e., total volatiles minus water and excluded compounds, in pounds of
						VOC per gallon of VOC.
(d)
					 An owner or operator of a coating line which utilizes a coating system as a
					 control strategy, which control strategy may also employ a control device, must
					 comply with the following provisions:
(1) the
					 coating system must be approved by the department prior to the use of the
					 coating system in the manufacture of a product for sale;
(2) coatings which are applied manually by
					 handheld spray guns cannot be utilized in a coating system;
(3) the emission differential (ED) for a
					 coating system must be determined using equation 7 below. The ED for the
					 coating system is the sum of the individual ED values calculated for every
					 coating used in the coating system. The ED calculation requirement is to be
					 performed each time the series of coatings in a coating system is changed. The
					 coating system ED must be less than or equal to zero before the coating system
					 may be operated.
Equation 7

where:
V is the actual coating volume used, minus water and
						excluded compounds, in gallons.
<<eta>> is the overall removal efficiency,
						expressed as:
Equation 8
Image
						5
where:
<<eta>>c is the
						percent CE, as determined by section
						228-1.6(d)(2) 
						of this Subpart.
<<eta>>d is the
						percent destruction and/or removal efficiency, as determined by section
						228-1.6(d)(1) 
						of this Subpart.
<<eta>> = 0, for coating systems without a
						control device and capture system.
dVOC = 7.36 pounds of VOC per
						gallon of VOC when (VOC)a = 0 and
						(Vn)a=1
When section
						228-1.6(d)(1) 
						of this Subpart applies, <<eta>> is the VOC solvent recovery
						fraction.
All other terms are defined in subdivision (c) of this
						section.
(4) the ED figures
					 for the individual coating used in the coating system must be calculated on an
					 instantaneous basis. There is no averaging period for individual coatings which
					 are part of a coating system; and
(5) the method or instrument by which the
					 owner or operator will measure or calculate the volume of coating applied must
					 be approved by the department.
