§63.11925 What are my initial and continuous compliance requirements for process vents?
(a) Emission limits. Each process vent must meet the emission limits in Table 1 or 2 to this subpart prior to the vent stream being exposed to the atmosphere. The emission limits in Table 1 or 2 to this subpart apply at all times. The emission limits in Table 1 or 2 to this subpart must not be met through dilution.
(b) Closed vent systems and control devices. Each batch process vent, continuous process vent and miscellaneous vent that is in HAP service must be routed through a closed vent system to a control device. All gas streams routed to the closed vent system and control device must be for a process purpose and not for the purpose of diluting the process vent to meet the emission limits in Table 1 or 2 to this subpart. Each control device used to comply with paragraph (a) of this section must meet the requirements of §§63.11925 and 63.11940, and all closed vent systems must meet the requirements in §63.11930. You must not use a flare to comply with the emission limits in Table 1 or 2 to this subpart.
(c) General monitoring requirements. Except as provided in paragraphs (c)(1) through (3) of this section, for each control device used to comply with the process vent emission limit specified in Table 1 or 2 to this subpart, you must install and operate a continuous parameter monitoring system (CPMS) to monitor each operating parameter specified in §63.11940(a) through (h) to comply with your operating limit(s) required in §63.11880(b).
(1) Hydrogen chloride continuous emission monitoring system (CEMS). In lieu of establishing operating limits in §63.11880(b) and using CPMS to comply with the operating limits, as specified in §63.11940(a) through (h), upon promulgation of a performance specification for hydrogen chloride CEMS, new and existing sources have the option to install a hydrogen chloride CEMS to demonstrate initial and continuous compliance with the hydrogen chloride emission limit for process vents, as specified in paragraphs (d) and (e) of this section.
(2) Dioxin/furan CEMS. In lieu of establishing operating limits in §63.11880(b) and using CPMS to comply with the operating limits as specified in §63.11940(a) through (h), upon promulgation of a performance specification for dioxin/furan CEMS, new and existing sources have the option to install a dioxin/furan CEMS to demonstrate initial and continuous compliance with the dioxins/furan emission limit for process vents, as specified in paragraphs (d) and (e) of this section.
(3) Total hydrocarbon CEMS. In lieu of establishing operating limits in §63.11880(b) and using CPMS to comply with the operating limits as specified in §63.11940(a) through (h), new and existing affected sources have the option to install a total hydrocarbon CEMS to demonstrate initial and continuous compliance with the total hydrocarbons or total organic HAP emission limit for process vents, as specified in paragraphs (d) and (e) of this section.
(d) Initial compliance. To demonstrate initial compliance with the emission limits in Table 1 or 2 to this subpart, you must comply with paragraphs (d)(1) through (5) of this section.
(1) You must conduct an initial inspection as specified in §63.11930(d) for each closed vent system.
(2) For each CEMS and CPMS required or that you elect to use as specified in paragraph (c) of this section, you must prepare the quality control program and site-specific performance evaluation test plan as specified in §63.11935(b) and site-specific monitoring plan specified in §63.11935(c), respectively.
(3) For each CEMS and CPMS required or that you elect to use as specified in paragraph (c) of this section, you must install, operate, and maintain the CEMS and CPMS as specified in §§63.11935(b) and (c), respectively, and you must conduct an initial site-specific performance evaluation test according to your site-specific monitoring plan and §§63.11935(b)(3) and (c)(4), respectively.
(4) For each emission limit for which you use a CEMS to demonstrate compliance, you must meet the requirements specified in §63.11890(c), and you must demonstrate initial compliance with the emission limits in Table 1 or 2 to this subpart based on 3-hour block averages of CEMS data collected at the minimum frequency specified in §63.11935(b)(2) and calculated using the data reduction method specified in §63.11935(e). For a CEMS used on a batch operation, you may use a data averaging period based on an operating block in lieu of the 3-hour averaging period.
(i) You must conduct an initial performance test according to the requirements in §63.11945 to demonstrate compliance with the total hydrocarbons or total organic HAP emission limit, vinyl chloride emission limit, hydrogen chloride emission limit, and dioxin/furan emission limit in Table 1 or 2 to this subpart.
(ii) During the performance test specified in paragraph (d)(5)(i) of this section, for each CPMS installed and operated as specified in paragraph (c) of this section, you must establish an operating limit as the operating parameter range, minimum operating parameter level, or maximum operating parameter level specified in §63.11935(d). You must meet the requirements specified in §63.11890(c). Each operating limit must be based on the data averaging period for compliance specified in Table 5 to this subpart using data collected at the minimum frequency specified in §63.11935(c)(2) and calculated using the data reduction method specified in §63.11935(e). For a CPMS used on a batch operation, you may use a data averaging period based on an operating block in lieu of the averaging period specified in Table 5 to this subpart.
(e) Continuous compliance. To demonstrate continuous compliance with the emission limits in Table 1 or 2 to this subpart for each process vent, you must comply with paragraphs (e)(1) through (5) of this section.
(1) You must meet the requirements in §63.11930 for each closed vent system.
(2) You must operate and maintain each CEMS and CPMS required in paragraph (c) of this section as specified in §63.11935(b) and (c), respectively.
(i) You must conduct a periodic site-specific CEMS performance evaluation test according to your quality control program and site-specific performance evaluation test plan specified in §63.11935(b)(1).
(ii) You must demonstrate continuous compliance with the emission limits in Table 1 or 2 to this subpart based on 3-hour block averages of CEMS data collected at the minimum frequency specified in §63.11935(b)(2), and calculated using the data reduction method specified in §63.11935(e). You must meet the requirements specified in §63.11890(c). For a CEMS used on a batch operation, you may use a data averaging period based on an operating block in lieu of the 3-hour averaging period.
(i) You must conduct a performance test once every 5 years according to the requirements in §63.11945 for each pollutant in Table 1 or 2 to this subpart.
(A) You must conduct periodic site-specific CPMS performance evaluation tests according to your site-specific monitoring plan and §63.11935(c).
(B) For each control device being monitored, you must continuously collect CPMS data consistent with §63.11890(c) and your site-specific monitoring plan. You must continuously determine the average value of each monitored operating parameter based on the data collection and reduction methods specified in §§63.11935(c)(2) and 63.11935(e), and the applicable data averaging period for compliance specified in Table 5 to this subpart for all periods the process is operating. For a CPMS used on a batch operation, you may use a data averaging period based on an operating block in lieu of the averaging periods specified in Table 5 to this subpart.
(g) Emission profile. You must characterize each process vent by developing an emissions profile for each contributing continuous process vent, miscellaneous vent and batch process vent according to paragraphs (g)(1) through (3) of this section.
(ii) Determine emissions per episode and batch process vent emissions according to the procedures specified in §63.11950.
(i)(A) Method 1 or 1A of 40 CFR part 60, appendix A-1, as appropriate, shall be used for selection of the sampling site. The sampling site shall be after the last recovery device (if any recovery devices are present) but prior to being combined with any other continuous process vent, batch process vent, or miscellaneous vent, prior to the inlet of any control device that is present and prior to release to the atmosphere.
(h) Process changes. Except for temporary shutdowns for maintenance activities, if you make a process change such that, as a result of that change, you are subject to a different process vent limit in Table 1 or 2 to this subpart, then you must meet the requirements of §63.11896.
