Section 096-161-4 - Compliance Test MethodsThe 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.B. For any offset lithographic printing press that is subject to the requirements of Section 3 A(2) Fountain Solution limits of this Chapter, compliance with the VOC content of the as-applied fountain solution shall be determined by one of the methods in paragraphs 4B(1) and (2) (below) of this Chapter except when paragraph 4B(4) is applicable: (1) US EPA Method 24 shall be used to determine the VOC content of the as-applied fountain solution;(2) If diluted prior to use, a calculation shall be performed for VOC content that combines US EPA Method 24 analytical data for the concentrated materials used to prepare the as-applied fountain solution and the proportions in which they are mixed to make the as-applied fountain solution. The analysis of the concentrated material(s) may be performed by the manufacturer/supplier(s) of those material(s). The analytical data may be derived from a material safety data sheet (MSDS) or equivalent information from the supplier as long as it is based on US EPA Method 24 results; or(3) If not diluted prior to use, the owner or operator shall use formulation information provided by the supplier, such as a MSDS sheet or equivalent information from the supplier. In the event of a dispute between information provided by the supplier and data obtained by US EPA Method 24, the data obtained by US EPA Method 24 shall be employed.(4) For any offset lithographic printing press that is subject to the Fountain Solution requirements of Sections 3 A(2)(a) (ii) and (iii) of this Chapter, when adding alcohol to a fountain solution batch previously tested in accordance with one of the compliance test methods contained herein, in lieu of the methods in paragraphs 4B(1) to (3) above, the owner or operator shall determine the VOC (alcohol) content of the altered fountain solution using a hydrometer.C.For any offset lithographic printing press that is subject to the refrigerated fountain solution temperature requirements of 3A(2)(a)(iii) and 3A(2)(b)(iii) of this Chapter, a thermometer or other temperature detection device capable of reading to 0.5 degrees Fahrenheit shall be used to ensure that any refrigerated fountain solution reservoirs are maintained at or below sixty degrees Fahrenheit at all times.D.For any offset lithographic printing press that is complying via the Cleaning Solution requirements for VOC content of 70% by weight limits of this Chapter, the VOC content of cleaning solutions shall be determined by one of the following methods: (1) US EPA Method 24 shall be used to determine the VOC content of the cleaning solution;(2) If diluted prior to use, a calculation shall be performed for VOC content that combines US EPA Method 24 analytical data for the concentrated materials used to prepare the cleaning solution and the proportions in which they are mixed to make the as-applied cleaning solution. The analysis of the concentrated material(s) may be performed by the supplier(s) of those material(s). The analytical data may be derived from a material safety data sheet (MSDS) or equivalent information from the supplier as long as it is based on US EPA Method 24 results;(3) If not diluted prior to use, the owner or operator shall use formulation information provided by the supplier, such as MSDS sheet or equivalent information from the supplier. In the event of a dispute between information provided by the supplier and data obtained by US EPA Method 24, the data obtained by US EPA Method 24 shall be employed.E. For any offset lithographic printing press that is complying via the Cleaning Solution requirements for VOC composite vapor pressure limits of this Chapter, the VOC composite partial vapor pressure of cleaning solutions shall be determined by one of the following methods: (1) If diluted prior to use, calculate the VOC composite vapor pressure of the as-applied solvent by using the formula for "VOC composite vapor pressure" as follows: (a) Determine the identity and quantity of each compound in a blended organic solvent by using ASTM D2306, or by using ASTM E260 for organics and ASTM D3792 for water content, if applicable, or the manufacturer's product formulation data.(b) Determine the vapor pressure of each pure VOC component by using ASTM D2879 or publications such as Perry's Chemical Engineer's Handbook, CRC Handbook of Chemistry and Physics, or Lange's Handbook of Chemistry.(c) Calculate the VOC composite partial pressure of the solvent by using the formula for "VOC composite partial pressure" in Section 2 V. For the purpose of this calculation, the blended solvent shall be assumed to be an ideal solution where Raoult's Law applies. The partial vapor pressures of each compound at twenty degrees Celsius (sixty-eight degrees Fahrenheit) shall be used in the formula.(2) If not diluted prior to use, the owner or operator shall use formulation information provided by the supplier, such as a material safety data sheet (MSDS) or equivalent information from the supplier as long as it is based on results determined in accordance with the procedure specified above in Section 4 E(1) of this Chapter.06- 096 C.M.R. ch. 161, § 4
