Section 250-RICR-120-05-26.8 - Test Methods and Compliance ProceduresA. If a source uses air pollution control equipment to comply with the requirements of this regulation, compliance shall be demonstrated in accordance with 40 C.F.R. § 60, Appendix A, Method 18, Method 25, or Method 25A, incorporated in § 26.4(A) of this Part, or any other EPA approved method which has been approved by the Director.B. Selection of a method for testing compliance shall be based on consideration of total concentration and speciation of the organics present and on consideration of the potential presence of interfering gases. Only Method 25, which measures VOC as carbon, may be used for determining destruction efficiency of incinerators or catalytic incinerators.C. Except as indicated in §§ 26.8(C)(1) and (2) of this Part, a test shall consist of three (3) separate runs, each lasting a minimum of sixty (60) minutes, unless the Director determines that process variables dictate shorter sampling times. 1. When the test is being done 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 (3) separate runs, each coinciding with one or more complete sequences through the adsorption cycles of all the individual adsorber vessels.2. When the test is being done 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 (3) separate runs. Each run shall coincide with one or more complete adsorption cycles.D. Method 1 or 1A of 40 C.F.R. § 60 Appendix A-1, incorporated in § 26.4(A) of this Part, shall be used for velocity traverses.E. Method 2, 2A, 2C, or 2D of 40 C.F.R. § 60 Appendix A-1, incorporated in § 26.4(A) of this Part, shall be used to measure velocity and volumetric flow rates.F. Method 3 or 3A of 40 C.F.R. § 60 Appendix A-2, incorporated in § 26.4(A) of this Part, shall be used for O2 and CO2 analysis.G. Method 4 of 40 C.F.R. § 60 Appendix A-3, incorporated in § 26.4(A) of this Part, shall be used to measure stack gas moisture.H. Methods 2, 2A, 2C, 2D, 3, 3A and 4 of 40 C.F.R. § 60 Appendix A, incorporated in § 26.4(A) of this Part, shall be performed, as applicable, at least twice during each test run.I. Use of modifications of any of the analytical methods specified in §§ 26.8(A) through (H) of this Part shall be approved or disapproved by the Director on a case-by-case basis. An owner or operator shall submit sufficient documentation for the Director to find that the analytical methods specified in §§ 26.8(A) through (H) of this Part will yield inaccurate results and that the proposed modification is appropriate.250 R.I.
