§ 63.2350   What are my general requirements for complying with this subpart?
(a) You must be in compliance with the emission limitations, operating limits, and work practice standards in this subpart at all times when the equipment identified in § 63.2338(b)(1) through (5) is in OLD operation.
(b) Except as specified in paragraph (d) of this section, you must always operate and maintain your affected source, including air pollution control and monitoring equipment, according to the provisions in § 63.6(e)(1)(i).
(c) Except for emission sources not required to be controlled as specified in § 63.2343, you must develop a written startup, shutdown, and malfunction (SSM) plan according to the provisions in § 63.6(e)(3). Beginning no later than July 7, 2023, this paragraph no longer applies; however, for historical compliance purposes, a copy of the plan must be retained and available according to the requirements in § 63.2394(c) for five years after July 7, 2023.
(d) Beginning no later than the compliance dates specified in § 63.2342(e), paragraph (b) of this section no longer applies. Instead, at all times, you must operate and maintain any affected source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require you to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether a source is operating in compliance with operation and maintenance requirements will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source.
§ 63.2354   What performance tests, design evaluations, and performance evaluations must I conduct?
(a)(1) For each performance test that you conduct, you must use the procedures specified in subpart SS of this part and the provisions specified in paragraph (b) of this section.
(2) For each design evaluation you conduct, you must use the procedures specified in subpart SS of this part. You must also comply with the requirements specified in § 63.2346(l).
(3) For each performance evaluation of a continuous emission monitoring system (CEMS) you conduct, you must follow the requirements in § 63.8(e) and paragraph (d) of this section. For CEMS installed after the compliance date specified in § 63.2342(e), conduct a performance evaluation of each CEMS within 180 days of installation of the monitoring system.
(b)(1) Except as specified in paragraph (b)(6) of this section, for nonflare control devices, you must conduct each performance test according to the requirements in § 63.7(e)(1), and either § 63.988(b), § 63.990(b), or § 63.995(b), using the procedures specified in § 63.997(e).
(2) You must conduct three separate test runs for each performance test on a nonflare control device as specified in §§ 63.7(e)(3) and 63.997(e)(1)(v). Each test run must last at least 1 hour, except as provided in § 63.997(e)(1)(v)(A) and (B).
(3)(i) In addition to Method 25 or 25A (40 CFR part 60, appendix A-7), to determine compliance with the TOC emission limit, you may use Method 18 (40 CFR part 60, appendix A-6) or Method 320 of appendix A to this part to determine compliance with the total organic HAP emission limit. You may not use Method 18 or Method 320 of appendix A to this part if the control device is a combustion device, and you must not use Method 320 of appendix A to this part if the gas stream contains entrained water droplets. All compounds quantified by Method 320 of appendix A to this part must be validated according to Section 13.0 of Method 320 of appendix A to this part. As an alternative to Method 18, for determining compliance with the total organic HAP emission limit, you may use ASTM D6420-18 (incorporated by reference, see § 63.14), under the conditions specified in paragraph (b)(3)(ii) of this section.
(A) If you use Method 18 (40 CFR 60, appendix A-6) or Method 320 of appendix A to this part to measure compliance with the percentage efficiency limit, you must first determine which organic HAP are present in the inlet gas stream ( i.e., uncontrolled emissions) using knowledge of the organic liquids or the screening procedure described in Method 18. In conducting the performance test, you must analyze samples collected simultaneously at the inlet and outlet of the control device. Quantify the emissions for the same organic HAP identified as present in the inlet gas stream for both the inlet and outlet gas streams of the control device.
(B) If you use Method 18 (40 CFR part 60, appendix A-6) or Method 320 of appendix A to this part, to measure compliance with the emission concentration limit, you must first determine which organic HAP are present in the inlet gas stream using knowledge of the organic liquids or the screening procedure described in Method 18. In conducting the performance test, analyze samples collected as specified in Method 18 at the outlet of the control device. Quantify the control device outlet emission concentration for the same organic HAP identified as present in the inlet or uncontrolled gas stream.
(ii) You may use ASTM D6420-18 (incorporated by reference, see § 63.14), to determine compliance with the total organic HAP emission limit if the target concentration for each HAP is between 150 parts per billion by volume and 100 ppmv and either of the conditions specified in paragraph (b)(2)(ii)(A) or (B) of this section exists. For target compounds not listed in Section 1.1 of ASTM D6420-18 and not amenable to detection by mass spectrometry, you may not use ASTM D6420-18.
(A) The target compounds are those listed in Section 1.1 of ASTM D6420-18 (incorporated by reference, see § 63.14); or
(B) For target compounds not listed in Section 1.1 of ASTM D6420-18 (incorporated by reference, see § 63.14), but potentially detected by mass spectrometry, you must demonstrate recovery of the compound and the additional system continuing calibration check after each run, as detailed in ASTM D6420-18, Section 10.5.3, must be followed, met, documented, and submitted with the data report, even if there is no moisture condenser used or the compound is not considered water-soluble.
(iii) You may use ASTM D6348-12e1 (incorporated by reference, see § 63.14) instead of Method 320 of appendix A to this part under the conditions specified in footnote 4 of Table 5 to this subpart.
(4) If a principal component of the uncontrolled or inlet gas stream to the control device is formaldehyde, you must use Method 316 of appendix A to this part, Method 320 of appendix A to this part, or Method 323 of appendix A to this part for measuring the formaldehyde, except you must not use Method 320 or Method 323 of appendix A to this part if the gas stream contains entrained water droplets. If you use Method 320 of appendix A to this part, formaldehyde must be validated according to Section 13.0 of Method 320 of appendix A to this part. You must measure formaldehyde either at the inlet and outlet of the control device to determine control efficiency or at the outlet of a combustion device for determining compliance with the emission concentration limit. You may use ASTM D6348-12e1 (incorporated by reference, see § 63.14) instead of Method 320 of appendix A to this part under the conditions specified in footnote 4 of Table 5 to this subpart.
(5) Except as specified in paragraph (b)(6) of this section, you may not conduct performance tests during periods of SSM, as specified in § 63.7(e)(1).
(6) Beginning no later than the compliance dates specified in § 63.2342(e), paragraphs (b)(1) and (5) of this section no longer apply. Instead, you must conduct each performance test according to the requirements in paragraphs (b)(6)(i) and (ii) of this section.
(i) In lieu of the requirements specified in § 63.7(e)(1), you must conduct performance tests under such conditions as the Administrator specifies based on representative performance of the affected source for the period being tested. Representative conditions exclude periods of startup and shutdown. You may not conduct performance tests during periods of malfunction. You 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 normal operation. Upon request, you must make available to the Administrator such records as may be necessary to determine the conditions of performance tests.
(ii) Pursuant to paragraph (b)(6)(i) of this section, you must conduct each performance test according to the requirements in either § 63.988(b), § 63.990(b), or § 63.995(b), using the procedures specified in § 63.997(e). You must also comply with the requirements specified in § 63.2346(l).
(c) To determine the HAP content of the organic liquid, you may use Method 311 of appendix A to this part, ASTM D6886-18 (incorporated by reference, see § 63.14), or other method approved by the Administrator. If you use ASTM D6886-18 to determine the HAP content, you must use either Method B or Method B in conjunction with Method C, as described in section 4.3 of ASTM D6886-18. In addition, you may use other means, such as voluntary consensus standards, safety data sheets (SDS), or certified product data sheets, to determine the HAP content of the organic liquid. If the method you select to determine the HAP content provides HAP content ranges, you must use the upper end of each HAP content range in determining the total HAP content of the organic liquid. The EPA may require you to test the HAP content of an organic liquid using Method 311 of appendix A to this part or other method approved by the Administrator. For liquids that contain any amount of formaldehyde or carbon tetrachloride, you may not use Method 311of appendix A to this part. If the results of the Method 311 of appendix A to this part (or any other approved method) are different from the HAP content determined by another means, the Method 311 of appendix A to this part (or approved method) results will govern. For liquids that contain any amount of formaldehyde or carbon tetrachloride, if the results of ASTM D6886-18 using method B or C in section 4.3 (or any other approved method) are different from the HAP content determined by another means, ASTM D6886-18 using method B or C in section 4 (or approved method) results will govern.
(d) Each VOC CEMS must be installed, operated, and maintained according to the requirements of one of the following performance specifications in appendix B to part 60 of this chapter: Performance Specification 8, Performance Specification 8A, Performance Specification 9, or Performance Specification 15. You must also comply with the requirements of procedure 1 of appendix F to part 60 of this chapter, for CEMS using Performance Specification 8 or 8A.
(1) For CEMS using Performance Specification 9 or 15 (40 CFR part 60, appendix B), determine the target analyte(s) for calibration using either process knowledge or the screening procedures of Method 18 (40 CFR part 60, appendix A-6).
(2) For CEMS using Performance Specification 8A (40 CFR part 60, appendix B), conduct the relative accuracy test audits required under Procedure 1 (40 CFR part 60, appendix F) in accordance with Sections 8 and 11 of Performance Specification 8 (40 CFR part 60, appendix B). The relative accuracy must meet the criteria of Section 13.2 of Performance Speciation 8 (40 CFR part 60, appendix B).
(3) For CEMS using Performance Specification 8 or 8A of 40 CFR part 60, appendix B, calibrate the instrument on methane and report the results as carbon (C1). Use Method 25A of 40 CFR part 60, appendix A-7 as the reference method for the relative accuracy tests.
(4) If you are required to monitor oxygen in order to conduct concentration corrections, you must use Performance Specification 3 (40 CFR part 60, appendix B), to certify your oxygen CEMS, and you must comply with procedure 1 (40 CFR part 60, appendix F). Use Method 3A (40 CFR part 60, appendix A-2), as the reference method when conducting a relative accuracy test audit.

(d) For each CEMS, you must locate the sampling probe or other interface at a measurement location such that you obtain representative measurements of emissions from the regulated source and comply with the applicable requirements specified in § 63.2354(d).
§ 63.2370   How do I demonstrate initial compliance with the emission limitations, operating limits, and work practice standards?
(a) You must demonstrate initial compliance with each emission limitation and work practice standard that applies to you as specified in Tables 6 and 7 to this subpart.
(b) You demonstrate initial compliance with the operating limits requirements specified in § 63.2346(e) by establishing the operating limits during the initial performance test or design evaluation.
(c) You must submit the results of the initial compliance determination in the Notification of Compliance Status according to the requirements in § 63.2382(d). If the initial compliance determination includes a performance test and the results are submitted electronically via the Compliance and Emissions Data Reporting Interface (CEDRI) in accordance with § 63.2386(g), the unit(s) tested, the pollutant(s) tested, and the date that such performance test was conducted may be submitted in the Notification of Compliance Status in lieu of the performance test results. The performance test results must be submitted to CEDRI by the date the Notification of Compliance Status is submitted.
§ 63.2374   When do I monitor and collect data to demonstrate continuous compliance and how do I use the collected data?
(a) You must monitor and collect data according to subpart SS of this part, and paragraphs (b) and (c) of this section. You must also comply with the requirements specified in § 63.2346(l).
(b) When using a control device to comply with this subpart, you must monitor continuously or collect data at all required intervals at all times that the emission source and control device are in OLD operation, except for CMS malfunctions (including any malfunction preventing the CMS from operating properly), associated repairs, and required quality assurance or control activities (including, as applicable, calibration checks and required zero and span adjustments).
(c) Do not use data recorded during CMS malfunctions, associated repairs, required quality assurance or control activities, or periods when emissions from organic liquids are not routed to the control device in data averages and calculations used to report emission or operating levels. Do not use such data in fulfilling a minimum data availability requirement, if applicable. You must use all of the data collected during all other periods, including periods of SSM, in assessing the operation of the control device.
§ 63.2378   How do I demonstrate continuous compliance with the emission limitations, operating limits, and work practice standards?
(a) You must demonstrate continuous compliance with each emission limitation, operating limit, and work practice standard in Tables 2 through 4 to this subpart that applies to you according to the methods specified in subpart SS of this part, and in Tables 8 through 10 to this subpart, as applicable. You must also comply with the requirements specified in § 63.2346(l).
(b) Except as specified in paragraph (e) of this section, you must follow the requirements in § 63.6(e)(1) and (3) during periods of startup, shutdown, malfunction, or nonoperation of the affected source or any part thereof. In addition, the provisions of paragraphs (b)(1) through (3) of this section apply.
(1) The emission limitations in this subpart apply at all times except during periods of nonoperation of the affected source (or specific portion thereof) resulting in cessation of the emissions to which this subpart applies. The emission limitations of this subpart apply during periods of SSM, except as provided in paragraphs (b)(2) and (3) of this section. However, if a SSM, or period of nonoperation of one portion of the affected source does not affect the ability of a particular emission source to comply with the emission limitations to which it is subject, then that emission source is still required to comply with the applicable emission limitations of this subpart during the startup, shutdown, malfunction, or period of nonoperation.
(2) The owner or operator must not shut down control devices or monitoring systems that are required or utilized for achieving compliance with this subpart during periods of SSM while emissions are being routed to such items of equipment if the shutdown would contravene requirements of this subpart applicable to such items of equipment. This paragraph (b)(2) does not apply if the item of equipment is malfunctioning. This paragraph (b)(2) also does not apply if the owner or operator shuts down the compliance equipment (other than monitoring systems) to avoid damage due to a contemporaneous SSM of the affected source or portion thereof. If the owner or operator has reason to believe that monitoring equipment would be damaged due to a contemporaneous SSM of the affected source of portion thereof, the owner or operator must provide documentation supporting such a claim in the next Compliance report required in Table 11 to this subpart, item 1. Once approved by the Administrator, the provision for ceasing to collect, during a SSM, monitoring data that would otherwise be required by the provisions of this subpart must be incorporated into the SSM plan.
(3) During SSM, you must implement, to the extent reasonably available, measures to prevent or minimize excess emissions. For purposes of this paragraph (b)(3), the term “excess emissions” means emissions greater than those allowed by the emission limits that apply during normal operational periods. The measures to be taken must be identified in the SSM plan, and may include, but are not limited to, air pollution control technologies, recovery technologies, work practices, pollution prevention, monitoring, and/or changes in the manner of operation of the affected source. Back-up control devices are not required, but may be used if available.
(c) Except as specified in paragraph (e) of this section, periods of planned routine maintenance of a control device used to control storage tanks or transfer racks, during which the control device does not meet the emission limits in Table 2 to this subpart, must not exceed 240 hours per year.
(d) Except as specified in paragraph (e) of this section, if you elect to route emissions from storage tanks or transfer racks to a fuel gas system or to a process, as allowed by § 63.982(d), to comply with the emission limits in Table 2 to this subpart, the total aggregate amount of time during which the emissions bypass the fuel gas system or process during the calendar year without being routed to a control device, for all reasons (except SSM or product changeovers of flexible operation units and periods when a storage tank has been emptied and degassed), must not exceed 240 hours.
(e) Beginning no later than the compliance dates specified in § 63.2342(e), paragraphs (b) through (d) of this section no longer apply. Instead, you must be in compliance with each emission limitation, operating limit, and work practice standard specified in paragraph (a) of this section at all times, except during periods of nonoperation of the affected source (or specific portion thereof) resulting in cessation of the emissions to which this subpart applies and must comply with the requirements specified in paragraphs (e)(1) through (4) of this section, as applicable. Equipment subject to the work practice standards for equipment leak components in Table 4 to this subpart, item 4 are not subject to this paragraph (e).
(1) Except as specified in paragraphs (e)(3) and (4) of this section, the use of a bypass line at any time on a closed vent system to divert a vent stream to the atmosphere or to a control device not meeting the requirements specified in paragraph (a) of this section is an emissions standards deviation.
(2) If you are subject to the bypass monitoring requirements of § 63.983(a)(3), then you must continue to comply with the requirements in § 63.983(a)(3) and the recordkeeping and reporting requirements in §§ 63.998(d)(1)(ii) and 63.999(c)(2), in addition to § 63.2346(l), the recordkeeping requirements specified in § 63.2390(g), and the reporting requirements specified in § 63.2386(c)(12).
(3) Periods of planned routine maintenance of a control device used to control storage tank breathing loss emissions, during which the control device does not meet the emission limits in Table 2 or 2b to this subpart, must not exceed 240 hours per year. The level of material in the storage tank shall not be increased during periods that the closed-vent system or control device is bypassed to perform planned routine maintenance.
(4) If you elect to route emissions from storage tanks to a fuel gas system or to a process, as allowed by § 63.982(d), to comply with the emission limits in Table 2 or 2b to this subpart, the total aggregate amount of time during which the breathing loss emissions bypass the fuel gas system or process during the calendar year without being routed to a control device, for all reasons (except product changeovers of flexible operation units and periods when a storage tank has been emptied and degassed), must not exceed 240 hours. The level of material in the storage tank shall not be increased during periods that the fuel gas system or process is bypassed.
(f) The CEMS data must be reduced to daily averages computed using valid data consistent with the data availability requirements specified in § 63.999(c)(6)(i)(B) through (D), except monitoring data also are sufficient to constitute a valid hour of data if measured values are available for at least two of the 15-minute periods during an hour when calibration, quality assurance, or maintenance activities are being performed. In computing daily averages to determine compliance with this subpart, you must exclude monitoring data recorded during CEMS breakdowns, out of control periods, repairs, maintenance periods, calibration checks, or other quality assurance activities.
§ 63.2380   What are my requirements for certain flares?
(a) Beginning no later than the compliance dates specified in § 63.2342(e), if you reduce organic HAP emissions by venting emissions through a closed vent system to a steam-assisted, air-assisted, or non-assisted flare to control emissions from a storage tank, low throughput transfer rack, or high throughput transfer rack that is subject to control based on the criteria specified in Tables 2 or 2b to this subpart, then the flare requirements specified in § 63.11(b); subpart SS of this part; the provisions specified in items 7.a through 7.d of Table 3 to this subpart; Table 8 to this subpart; and the provisions specified in items 1.a.iii and 2.a.iii, and items 7.a through 7.d.2 of Table 9 to this subpart no longer apply. Instead, you must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671, including the provisions in Tables 12 and 13 to subpart CC of this part, except as specified in paragraphs (b) through (m) of this section. For purposes of compliance with this paragraph, the following terms are defined in § 63.641: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.
