Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 161 - GRAPHIC ARTS - OFFSET LITHOGRAPHY AND LETTERPRESS PRINTING › Section 096-161-4 - Compliance Test Methods

Current through 2024-29, July 17, 2024
The following test methods shall be used, except where the
				  use of an adaptation or alternative to any of the analytical methods specified
				  in this section shall be approved by the Department and US EPA on a
				  case-by-case basis. The owner or operator shall submit sufficient documentation
				  for the Department and US EPA to find that the analytical methods specified
				  below would yield inaccurate results and that the proposed adaptation is
				  appropriate.
A.For any heatset web
				offset or heatset web letterpress printing press that is subject to the
				requirements of Section 3 B VOC Emission Control Requirements for Heatset
				Dryers, compliance shall be determined by performing emission tests in
				accordance with the following:
(1) For the
				purpose of demonstrating compliance with the emission control requirements in
				Section 3 B of this Chapter, the affected source shall be run at typical
				operating conditions and flow rates compatible with scheduled production during
				any emission testing.
(2) 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
				differential pressure gauge.
(3)
				The following US EPA test methods (in 40 CFR Part 60, Appendix A) shall be used
				to demonstrate compliance with the applicable emission control requirement
				inSection 3 B of this Chapter.
(a) US EPA
				Method 1 or 1A, as appropriate, shall be used to select the sampling
				sites.
(b) US EPA Method 2, 2A, 2C,
				or 2D, as appropriate, shall be used to determine the velocity and volumetric
				flow rate of the exhaust stream.
(c) US EPA Method 3 or 3A, as appropriate,
				shall be used to determine the concentration of O2 and
				CO2.
(d) US
				EPA Method 4 shall be used to determine moisture content.
(e) US EPA Method 18, 25, or 25A shall be
				used to determine the VOC concentration of the exhaust stream entering and
				exiting the control device, unless the alternate limit of twenty ppmv as
				specified in Section 3 B of this Chapter is being met, in which case only the
				VOC concentration of the exit exhaust shall be determined. In cases where the
				anticipated outlet VOC concentration of the control device is less than fifty
				ppmv as carbon, Method 25A shall be used.
(i)
				If the average concentrations in the outlet of a thermal or catalytic oxidizer
				measured by Method 25A are greater than fifty ppmv as carbon, Method 18 or 25
				may be used to determine non-VOC components (methane and ethane) to correct the
				outlet VOC readings, unless the director determines that the uncorrected Method
				25A results are acceptable.
(ii) A
				compliance test shall consist of up to three separate runs, each lasting a
				minimum of sixty minutes, unless the director determines that process variables
				dictate shorter sampling times.
(iii) US EPA Method 25 specifies a minimum
				probe temperature of two hundred sixty-five degrees Fahrenheit. The probe shall
				be heated to at least the temperature required to prevent condensation as
				specified in the stack test protocol required by the governing air emission
				license, or otherwise approved in writing by the Department and EPA.
(iv) US EPA Method 25A specifies a minimum
				temperature of two hundred twenty degrees Fahrenheit for the sampling
				components leading to the analyzer. The sampling components and flame
				ionization detector block shall be heated to at least the temperature required
				to prevent condensation as specified in the stack test protocol required by the
				governing air emission license, or otherwise approved by the Department and
				EPA.
