Tenn. Comp. R. & Regs. 1200-03-18-.84 - TEST METHODS AND COMPLIANCE PROCEDURES: DETERMINING THE DESTRUCTION OR REMOVAL EFFICIENCY OF A CONTROL DEVICE
(1) One of the following test methods must be used to determine volatile organic compound (VOC) concentrations of a gas stream:
(a) Reference Method 18;
(b) Reference Method 25; or
(c) Reference Method 25A.
(2) Reference Method 25 or 25A shall be used for determining destruction efficiency of incinerators and catalytic incinerators, unless an alternate method is approved by the Technical Secretary and the EPA.
(3) Except as indicated in Subparagraphs (a) and (b) of this paragraph, a test shall consist of three separate runs, each lasting a minimum of 60 minutes (min):
(a) When the method is to be used to determine the efficiency of a fixed-bed carbon adsorption system with a common exhaust stack for all of the individual adsorber vessels, the test shall consist of three separate runs, each coinciding with one or more complete sequences through the adsorption cycles of all the individual adsorber vessels.
(b) When the method is to be used to determine the efficiency of a fixed-bed carbon adsorption system with individual exhaust stacks for each adsorber vessel, each adsorber vessel shall be tested individually. The test for each adsorber vessel shall consist of three separate runs. Each run shall coincide with one or more complete adsorption cycles.
(4) Reference Method 1 or 1A shall be used for velocity traverses.
(5) Reference Method 2, 2A, 2C, or 2D shall be used for velocity and volumetric flow rates.
(6) Reference Method 3 or 3A shall be used for O2 or CO2 analysis.
(7) Reference Method 4 shall be used for stack gas moisture.
(8) Reference Methods 2, 2A, 2C, 2D, 3, 3A, and 4 shall be performed, as applicable, at least twice during each test run.
(9) Use of an adaptation or alternative to any of the methods specified in this rule shall be approved by the Technical Secretary and EPA on a case-by-case basis. An owner or operator shall submit sufficient documentation for the Technical Secretary and EPA to find that the analytical methods specified will yield inaccurate results and that the proposed adaptation or alternative is appropriate, or that the proposed adaptation or alternative will yield results as accurate as will the specified analytical methods.
