Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 5 - STATE AIR POLLUTION CONTROL BOARD › Chapter 40 - EXISTING STATIONARY SOURCES › Part II - Emission Standards › Article 56.1 - Emission Standards for Offset Lithographic Printing Operations in the Northern Virginia Volatile Organic Compound Emissions Control Area, 8-hour Ozone Standard (Rule 4-56.1) › Section 9VAC5-40-8434 - Compliance

Current through Register Vol. 40, No. 24, July 15, 2024
A. The provisions
					 of 9VAC5-40-20(Compliance)
					 apply.
B. If requested by the
					 board, an emission test of the control device installed on a heatset web offset
					 lithographic printing process dryer shall be performed to demonstrate
					 compliance with the provisions of 9VAC5-40-8424 B and C. The negative dryer
					 pressure shall be established during the initial test using an airflow
					 direction indicator, such as a smoke stick or aluminum ribbons, or a
					 differential pressure gauge. The board may accept the results of an emission
					 test conducted prior to the compliance date specified in 9VAC5-40-8436 if the
					 owner or operator provides information and data that demonstrate that the test
					 demonstrated compliance with the provisions of 9VAC5-40-8424 B and C.
C. Continuing compliance with the heatset web
					 offset lithographic printing process dryer control requirements in
					 9VAC5-40-8424 B and C shall be demonstrated for the catalytic or thermal
					 oxidation control device by monitoring the control device in accordance with
					 9VAC5-40-8440 B 3, B 4, and B 5. The owner shall maintain the three-hour
					 average of the monitored temperature at a temperature no less than 50°F
					 below the three-hour average temperature that was recorded during the most
					 recent performance test during which compliance was demonstrated. In the
					 absence of performance test results acceptable to the board that provide dryer
					 control device temperatures that demonstrate continuing compliance with the
					 requirements in 9VAC5-40-8424 B and C, control device temperatures that
					 demonstrate compliance with manufacturer recommendations may be considered by
					 the board to demonstrate compliance with heatset web offset lithographic
					 printing process dryer control requirements in 9VAC5-40-8424 B and C.
D. A portion of the volatile organic
					 compounds contained in inks and cleaning solution is retained in the printed
					 web and in the shop towels used for cleaning. When applicable, the following
					 retention factors may be used in determining volatile organic compounds
					 emissions from offset lithographic printing operations:
1. A 20% volatile organic compound retention
					 factor may be used for petroleum ink oils contained in heatset inks that are
					 printed on absorptive substrates, meaning that 80% of the VOC (petroleum ink
					 oil) in the ink is emitted during the printing process and is available for
					 capture and control by an add-on pollution control device.
2. A 100% volatile organic compound retention
					 factor may be used for vegetable ink oils contained in heatset inks that are
					 printed on absorptive substrates, meaning that none of the VOC (vegetable ink
					 oil) in the ink is emitted during the printing process and available for
					 capture and control by an add-on pollution control device.
3. A 95% volatile organic compound retention
					 factor may be used for petroleum ink oils contained in sheet-fed and
					 non-heatset web inks printed on absorptive substrates, meaning that 5.0% of the
					 VOC (petroleum ink oil) in the ink is emitted during the printing
					 process.
4. A 100% volatile organic
					 compound retention factor may be used for vegetable ink oils contained in
					 sheet-fed and non-heatset web inks printed on absorptive substrates, meaning
					 that none of the VOC (vegetable ink oil) in the ink is emitted during the
					 printing process.
5. A 50% volatile
					 organic compound retention factor may be used for cleaning solution VOC in shop
					 towels for those cleaning solutions with a volatile organic compounds composite
					 vapor pressure of no more than 10 millimeters of mercury (Hg) at 20°C
					 (68°F) provided that the cleaning materials and used shop towels are kept
					 in closed containers.
