Current through Register Vol. 40, No. 24, July 15, 2024
A. The provisions of 9VAC5-45-30 (Emission
					 testing) apply.
B. Except as
					 provided in subsections D, E and F of this section, the VOC and solids content
					 of all nonaerosol adhesives, adhesive primers and cleanup solvents shall be
					 determined using either Reference Method 24 or SCAQMD "Determination of
					 Volatile Organic Compounds (VOC) In Various Materials" (see 9VAC5-20-21
					 ).
C. The organic content of exempt
					 organic compounds shall be determined using ASTM "Standard Test Method for
					 Determination of Dichloromethane and 1,1,1-Trichloroethane in Paints and
					 Coatings by Direct Injection into a Gas Chromatograph" (see 9VAC5-20-21 ), as
					 applicable.
D. The VOC content of
					 any plastic welding cement adhesive or primer shall be determined using SCAQMD
					 "Determination of Volatile Organic Compounds (VOC) in Materials Used for Pipes
					 and Fittings" (see 9VAC5-20-21 ).
E. To determine if a diluent is a reactive
					 diluent, the percentage of the reactive organic compound that becomes an
					 integral part of the finished materials shall be determined using SCAQMD
					 "Determination of Volatile Organic Compounds (VOC) in Materials Used for Pipes
					 and Fittings" (see 9VAC5-20-21 ).
F. The composite vapor pressure of organic
					 compounds in cleaning materials shall be determined by quantifying the amount
					 of each compound in the blend using ASTM "Standard Practice for Packed Column
					 Gas Chromatography" for organics and ASTM "Standard Test Method for Water
					 Content of Coatings by Direct Injection Into a Gas Chromatograph" for water
					 content (see 9VAC5-20-21 ), as applicable, and the following equation:

where:
Ppc = VOC composite partial
						pressure at 20ºC, in mm Hg.
Wi = Weight of the "i"th VOC
						compound, in grams, as determined by ASTM "Standard Practice for Packed Column
						Gas Chromatography" (see 9VAC5-20-21 ).
Ww = Weight of water, in grams as
						determined by ASTM "Standard Test Method for Water Content of Coatings by
						Direct Injection Into a Gas Chromatograph" (see 9VAC5-20-21 ).
We = Weight of the "i"th exempt
						compound, in grams, as determined by ASTM "Standard Practice for Packed Column
						Gas Chromatography" (see 9VAC5-20-21 ).
Mwi = Molecular weight of the
						"i"th VOC compound, in grams per g-mole, as given in chemical reference
						literature.
Mww = Molecular weight of water,
						18 grams per g-mole.
Mwe = Molecular weight of the
						"i"th exempt compound, in grams per g-mole, as given in chemical reference
						literature.
Vpi = Vapor pressure of the "i"th
						VOC compound at 20ºC, in mm Hg, as determined by subsection G of this
						section.
G. The vapor
					 pressure of each single component compound may be determined from ASTM
					 "Standard Test Method for Vapor Pressure-Temperature Relationship and Initial
					 Decomposition Temperature of Liquids by Isoteniscope " (see 9VAC5-20-21 ), from
					 chemical reference literature or from additional sources acceptable to the
					 board.
H. If air pollution control
					 equipment is used to meet the requirements of 9VAC5-45-650, the owner or
					 operator shall make the following determinations:
1. The measurement of capture efficiency
					 shall be conducted and reported in accordance with the EPA Technical Document
					 "Guidelines for Determining Capture Efficiency" (see 9VAC5-20-21 ).
2. The control efficiency shall be determined
					 in accordance with Reference Methods 25, 25A, 25B or CARB Method 100 (see
					 9VAC5-20-21 ), as appropriate.
