Current through Register Vol. 41, No. 3, September 23, 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.
E. The volatile organic compound content of
each batch of fountain solution shall be determined by one of the following
procedures:
1. Analysis by Reference Method 24
of a sample of the batch of fountain solution; or
2. Calculation which combines Reference
Method 24 analytical volatile organic compound content data for the
concentrated materials used to prepare the press-ready batch based on records
of the proportions in which they are mixed to make the batch. The analysis of
the concentrated materials may be performed by the supplier of the materials.
Mix proportions may be used to determine the volatile organic compound content
of the fountain solution as a substitute for Method 24 if the supplier has
provided Method 24 information for the volatile organic compound content of the
concentrates.
F. A
thermometer or other temperature detection device capable of reading to
0.5°F shall be used to ensure that any refrigerated fountain solution
recirculating reservoirs are maintained at or below 60°F at all
times.
G. The volatile organic
compound or volatile organic compound partial vapor pressure of each cleaning
solution shall be determined by one of the following procedures:
1. Analysis by Reference Method 24 for
volatile organic compound content or by an appropriate method for composite
partial vapor pressure of a sample of the cleaning solution; or
2. Calculation for volatile organic compound
content which combines Reference Method 24 analytical volatile organic compound
content data for the concentrated materials used to prepare the press-ready
batch based on records of the proportions in which they are mixed to make the
batch. The analysis of the concentrated materials may be performed by the
supplier of the material. Mix proportions may be used to determine the volatile
organic compound content of the cleaning solution as a substitute for Method 24
if the supplier has provided Method 24 information for the volatile organic
compound content of the concentrates.
