Current through Register Vol. 40, No. 24, July 15, 2024
A. The provisions of
					 9VAC5-40-30 (Emission testing)
					 apply.
B. For the purpose of
					 demonstrating compliance with the emission control requirements of this rule,
					 the affected facility shall be run under typical operating conditions and flow
					 rates compatible with scheduled production during any emission
					 testing.
C. Emissions tests shall
					 include an initial test within 90 days of start-up when the control device is
					 installed and operating that demonstrates compliance with the emission standard
					 in 9VAC5-40-7820.
D. The following reference methods (cited in
					 40 CFR Part 60, Appendix A) shall be used to demonstrate compliance with the
					 emission limit or percent reduction efficiency requirement in
					 9VAC5-40-7820. Alternate methods
					 may be used with the approval of the board.
1.
					 Reference Method 1 or 1A, as appropriate, shall be used to select the sampling
					 sites. The control device sampling sites for determining efficiency in reducing
					 volatile organic compounds (excluding methane and ethane) from the dryer
					 exhaust shall be placed before the control device inlet (after the dryer) and
					 at the outlet of the control device.
2. Reference Method 2, 2A, 2C, or 2D, as
					 appropriate, shall be used to determine the velocity and volumetric flow rate
					 of the exhaust stream.
3. Reference
					 Method 18, 25, or 25A shall be used to determine the volatile organic compound
					 concentration of the exhaust stream entering and exiting the control device.
					 Good judgment is required in determining the best applicable volatile organic
					 compound test method for each situation. The method selected shall be based on
					 consideration of the diversity of organic species present and their total
					 concentration and on consideration of the potential presence of interfering
					 gases. Because of the different response factors for the many organic compounds
					 formed during the combustion process, only Reference Method 25, which measures
					 volatile organic compounds as a carbon, shall be used; except in cases where
					 the expected outlet volatile organic compound concentration of the control
					 device is less than 100 ppmv as carbon, in which case Reference Method 25A
					 shall be used.
a. If average, nonmethane
					 volatile organic compound concentrations in the outlet of a thermal or
					 catalytic oxidizer measured by Reference Method 25A are found to be greater
					 than 100 ppmv as carbon, the board may request a repeat test to be conducted
					 using Reference Method 18 or 25.
b.
					 A test shall consist of three separate runs, each lasting a minimum of 60
					 minutes, unless the board determines that process variables dictates shorter
					 sampling times.
c. Reference Method
					 25 specifies a minimum probe and temperature of 265°F. To prevent
					 condensation, the probe should be heated to at least the gas stream
					 temperature, typically close to 350°F.
