§ 63.1450 What test methods and other procedures must I use to demonstrate initial compliance with the emission limitations and design standards?
(a) Filterable particulate matter emission limits. Before November 12, 2024, you must conduct each performance test to determine compliance with the filterable particulate matter emission limits in § 63.1444 or § 63.1446 that apply to you according to the requirements for representative test conditions specified in § 63.7(e)(1) and using the test methods and procedures in paragraphs (a)(1) through (5) of this section. On or after November 12, 2024, you must conduct each performance test to determine compliance with the filterable particulate matter emission limits in § 63.1444 or § 63.1446 that apply to you according to the requirements for representative test conditions specified in paragraph (a)(6) of this section and using the test methods and procedures in paragraphs (a)(1) through (5) of this section.
(1) Determine the concentration of filterable particulate matter according to the test methods in appendices A-1 through A-8 to 40 CFR part 60 as specified in paragraphs (a)(1)(i) through (v) of this section.
(i) Method 1 to select sampling port locations and the number of traverse points. Sampling ports must be located at the outlet of the control device and prior to any releases to the atmosphere.
(ii) Method 2, 2F, or 2G to determine the volumetric flow rate of the stack gas.
(iii) Method 3, 3A, or 3B to determine the dry molecular weight of the stack gas. The ANSI/ASME PTC 19-10-1981 Part 10 (incorporated by reference, see § 63.14) is an acceptable alternative to EPA Method 3B manual portion only but not the instrumental portion.
(iv) Method 4 to determine the moisture content of the stack gas.
(v) Method 5, 5D, or 17, as applicable, to determine the concentration of filterable particulate matter.
(2) As an alternative to using the applicable method specified in paragraph (a)(1)(v) of this section, you may determine filterable particulate matter emissions from the control device using Method 29 in appendix A-8 to 40 CFR part 60 provided that you follow the procedures and precautions prescribed in Method 29. If the control device is a positive pressure baghouse, you must also follow the measurement procedure specified in sections 8.1 through 8.3 of Method 5D in appendix A-3 to 40 CFR part 60.
(3) You must conduct three separate test runs for each performance test. Each test run must have a minimum sampling time of 60 minutes and a minimum sampling volume of 0.85 dscm. For the purpose of determining compliance with the applicable filterable particulate matter emission limit, the arithmetic mean of the results for the three separate test runs is used.
(4) For a venturi wet scrubber applied to emissions from an affected source and subject to emission limits and work practice standards in § 63.1444(j) or § 63.1446(d) for pressure drop and scrubber water flow rate, you must establish site-specific operating limits according to the procedures in paragraphs (a)(4)(i) and (ii) of this section.
(i) Using the continuous parameter monitoring system (CPMS) required in § 63.1452, measure and record the pressure drop and scrubber water flow rate during each run of the particulate matter performance test.
(ii) Compute and record the hourly average pressure drop and scrubber water flow rate for each individual test run. Your operating limits are the lowest average pressure drop and scrubber water flow rate value in any of the three runs that meet the applicable emission limit.
(5) For a control device other than a baghouse or venturi wet scrubber applied to emissions from an affected source and subject to work practice standards and emission limit(s) in § 63.1444(k) or § 63.1446(e) for appropriate, site-specific operating parameters that are representative and reliable indicators of the control device performance, you must establish a site-specific operating limit(s) according to the procedures in paragraphs (a)(5)(i) through (iv) of this section.
(i) Select one or more operating parameters, as appropriate for the control device design, that can be used as representative and reliable indicators of the control device operation.
(ii) Using the CPMS required in § 63.1452, measure and record the selected operating parameters for the control device during each run of the filterable particulate matter performance test.
(iii) Compute and record the hourly average value for each of the selected operating parameters for each individual test run. Your operating limits are the lowest value or the highest value, as appropriate for the selected operating parameter, measured in any of the three runs that meet the applicable emission limit.
(iv) You must prepare written documentation to support your selection of the operating parameters used for the control device. This documentation must include a description of each selected parameter, a rationale for why you chose the parameter, a description of the method used to monitor the parameter, and the data recorded during the performance test and used to set the operating limit(s).
(6) You must conduct each performance test that applies to your affected source under normal operating conditions of the affected source. The owner or operator may not conduct performance tests during periods of malfunction. The use of the bypass stack during a performance test of the process shall invalidate the performance test. The owner or operator must record the process information that is necessary to document operating conditions during the test and include in such record an explanation to support that such conditions represent the entire range of normal operation, including operational conditions for maximum emissions if such emissions are not expected during maximum production. The owner or operator shall make available to the Administrator such records as may be necessary to determine the conditions of performance tests.
(b) Nonsulfuric acid particulate matter emission limits. Before November 12, 2024, you must conduct each performance test to determine compliance with the nonsulfuric acid particulate matter emission limits in § 63.1444 that apply to you according to the requirements for representative test conditions specified in § 63.7(e)(1) and using the test methods and procedures in paragraphs (b)(1) and (2) of this section. On or after November 12, 2024, you must conduct each performance test to determine compliance with the nonsulfuric acid particulate matter emission limits in § 63.1444 that apply to you according to the requirements for representative test conditions specified in paragraph (b)(4) of this section and using the test methods and procedures in paragraphs (b)(1) through (3) of this section.
(1) Determine the concentration of nonsulfuric acid particulate matter according to the test methods in appendices A-1 through A-8 to 40 CFR part 60 as specified in paragraphs (b)(1)(i) through (v) of this section.
(i) Method 1 to select sampling port locations and the number of traverse points. Sampling ports must be located at the outlet of the control device and prior to any releases to the atmosphere.
(ii) Method 2, 2F, or 2G to determine the volumetric flow rate of the stack gas.
(iii) Method 3, 3A, or 3B to determine the dry molecular weight of the stack gas. The ANSI/ASME PTC 19-10-1981 Part 10 (incorporated by reference, see § 63.14) is an acceptable alternative to EPA Method 3B manual portion only but not the instrumental portion.
(iv) Method 4 to determine the moisture content of the stack gas.
(v) Method 5B to determine the nonsulfuric acid particulate matter emissions.
(2) You must conduct three separate test runs for each performance test. Each test run must have a minimum sampling time of 240 minutes and a minimum sampling volume of 3.4 dscm. For the purpose of determining compliance with the nonsulfuric acid particulate matter emission limit, the arithmetic mean of the results for the three separate test runs is used.
(3) For a control device applied to emissions from an affected source and subject to work practice standards and emission limit(s) in § 63.1444(i), (j), or (k) or § 63.1446(e) for appropriate, site-specific operating parameters that are representative and reliable indicators of the control device performance, you must establish a site-specific operating limit(s) according to the procedures in paragraphs (a)(5)(i) through (iv) of this section.
(4) You must conduct each performance test that applies to your affected source under normal operating conditions of the affected source. The owner or operator may not conduct performance tests during periods of malfunction. The use of the bypass stack during a performance test of the process shall invalidate the performance test. The owner or operator must record the process information that is necessary to document operating conditions during the test and include in such record an explanation to support that such conditions represent the entire range of normal operation, including operational conditions for maximum emissions if such emissions are not expected during maximum production. The owner or operator shall make available to the Administrator such records as may be necessary to determine the conditions of performance tests.
