Current through Register Vol. 41, No. 3, September 23, 2024
A. The provisions of
9VAC5-40-30 (Emission testing)
apply.
B. The following EPA test
methods shall be used to demonstrate compliance with the heatset web offset
lithographic printing process dryer control device control requirements in
9VAC5-40-8424 B and C.
1. Reference Method 1
or 1A, as appropriate, shall be used to select the sampling sites.
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 3 or 3A, as appropriate, shall be used to determine the concentration of
O2 and CO2.
4. Reference Method 4 shall be used to
determine moisture content.
5.
Reference Methods 18, 25, or 25A shall be used to determine the VOC
concentration of the dryer exhaust stream entering and exiting the control
device, unless the alternate limit in 9VAC5-40-8424 B 2 or C 2 is being met, in
which case only the VOC concentration of the dryer exhaust control device
outlet shall be determined.
6.
Reference Method 25A shall be used to determine the dryer exhaust control
device inlet and outlet VOC concentrations when the control device outlet
concentration is less than 50 parts per million volume (ppmv) VOC as
carbon.
7. If the control device is
an oxidizer, the combustion chamber temperature or catalyst bed inlet
temperature corresponding to destruction efficiencies that meet the
requirements of 9VAC5-40-8424 B or C, as appropriate, shall be
recorded.
C. The VOC
content of as-applied inks, varnishes and other coatings, fountain solutions,
and cleaning materials shall be determined using Reference Method 24.
1. The analysis of as-supplied materials may
be performed by the manufacturer or the supplier. Formulation information from
the manufacturer may be used in lieu of Reference Method 24 analysis unless the
board or the owner has reason to believe that the formulation information
provided by the manufacturer is inaccurate.
2. The owner may use VOC content information
provided by the manufacturer or supplier, such as the container label, the
product data sheet, or the Safety Data Sheet (SDS) to document the VOC content
of the as-supplied material.
3. If
fountain solution or cleaning materials are diluted by the owner prior to use,
a calculation that combines the as-supplied VOC content information provided by
the manufacturer or supplier, the VOC content of the diluent, and the
proportions in which they are mixed may be used to make a determination of VOC
content of the as-applied fountain solution or cleaning material in lieu of
Reference Method 24.
4. The owner
shall conduct Reference Method 24 testing of any as-applied fountain solution
or cleaning material used for offset lithographic printing operations at any
time at the board's request. The owner shall be prepared to sample as-applied
fountain solution or cleaning materials at all times.
D. A thermometer or other temperature
detection device capable of reading the temperature of the fountain solution to
within 0.5°F shall be used to determine compliance with fountain solution
temperature requirements in 9VAC5-40-8424 D.
E. The VOC composite partial vapor pressure
of cleaning solutions shall be determined using the formula provided in
9VAC5-40-8422 C or by an appropriate test method approved by the board.
1. The determination VOC composite partial
vapor pressure for as-supplied cleaning solutions may be performed by the
manufacturer or the supplier. The determination of as-applied composite vapor
pressure based upon the manufacturer's instructions for dilution may be
performed by the manufacturer or supplier.
2. The owner may use VOC composite partial
vapor pressure information provided by the manufacturer or supplier, such as
the container label, the product data sheet, or the Safety Data Sheet (SDS), to
document the VOC composite partial vapor pressure of the as-supplied or
as-applied cleaning materials.
3.
The following provisions apply to the determination of VOC composite partial
vapor pressure for cleaning materials that are diluted by the owner prior to
use:
a. If the dilution is made according to
the manufacturer's instructions, the VOC composite partial vapor pressure for
the as-applied cleaning material provided by the manufacturer or supplier may
be used.
b. If a dilution is made
and an as-applied VOC composite partial vapor pressure has not been provided by
the manufacturer or supplier, or if the dilution is not made according to the
manufacturer's instructions, then the owner shall determine the VOC composite
partial vapor pressure using the calculation method provided in 9VAC5-40-8422
C.
4. The owner shall
conduct testing of any as-applied cleaning materials used for offset
lithographic printing operations at any time at the board's request. The owner
shall be prepared to sample as-applied cleaning materials at all
times.

Virginia; §§ 110, 111, 123, 129, 171, 172, and 182 of the federal
Clean Air Act (40 CFR Parts 51 and 60).
