Initial Certification Procedures - the initial certification procedures for the HCl or HF CEMS used to provide data under this subpart are as follows: (40 CFR Part 63 Subpart UUUUU Appendix B 3)
 The HCl and/or HF CEMS must be certified according to Performance Specification 15 using the procedures for gas auditing and comparison to a reference method (RM) as specified in sections 3.1.1 and 3.1.2 below. (Please Note:EPA plans to publish a technology neutral performance specification and appropriate on-going quality-assurance requirements for HCl CEMS in the near future along with amendments to this appendix to accommodate their use.) (40 CFR Part 63 Subpart UUUUU Appendix B 3.1)
 The permittee must conduct a gas audit of the HCl and/or HF CEMS as described in section 9.1 of Performance Specification 15, with the exceptions listed in sections <IP_ADDRESS> and <IP_ADDRESS> below. (40 CFR Part 63 Subpart UUUUU Appendix B 3.1.1)
 The audit sample gas does not have to be obtained from the Administrator; however, it must be (1) from a secondary source of certified gases ( i.e. , independent of any calibration gas used for the daily calibration assessments) and (2) directly traceable to National Institute of Standards and Technology (NIST) or VSL Dutch Metrology Institute (VSL) reference materials through an unbroken chain of comparisons. If audit gas traceable to NIST or VSL reference materials is not available, the permittee may use a gas with a concentration certified to a specified uncertainty by the gas manufacturer. (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 Analyze the results of the gas audit using the calculations in section 12.1 of Performance Specification 15. The calculated correction factor (CF) from Eq. 6 of Performance Specification 15 must be between 0.85 and 1.15. The permitte does not have to test the bias for statistical significance. (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 The permittee must perform a relative accuracy test audit or RATA according to section <IP_ADDRESS> of Performance Specification 15 and the requirements below. Perform the RATA of the HCl or HF CEMS at normal load. Acceptable HCl/HF reference methods (RM) are Methods 26 and 26A in appendix A - 8 to part 60 of this chapter, Method 320 in Appendix A to this part, or ASTM D6348 - 03 (Reapproved 2010) "Standard Test Method for Determination of Gaseous Compounds by Extractive Direct Interface Fourier Transform Infrared (FTIR) Spectroscopy" (incorporated by reference, see §63.14), each applied based on the criteria set forth in Table 5 of this subpart. (40 CFR Part 63 Subpart UUUUU Appendix B 3.1.2)
 When ASTM D6348 - 03 is used as the RM, the following conditions must be met: (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 The test plan preparation and implementation in the Annexes to ASTM D6348 - 03, Sections A1 through A8 are mandatory;
 In ASTM D6348 - 03 Annex A5 (Analyte Spiking Technique), the percent (%) R must be determined for each target analyte (see Equation A5.5);
 For the ASTM D6348 - 03 test data to be acceptable for a target analyte, %R must be 70% >= R <= 130%; and
 The %R value for each compound must be reported in the test report and all field measurements corrected with the calculated %R value for that compound using the following equation:

 The relative accuracy (RA) of the HCl or HF CEMS must be no greater than 20 percent of the mean value of the RM test data in units of ppm on the same moisture basis. Alternatively, if the mean RM value is less than 1.0 ppm, the RA results are acceptable if the absolute value of the difference between the mean RM and CEMS values does not exceed 0.20 ppm. (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)

 Any additional stack gas flow rate, diluent gas, and moisture monitoring system(s) needed to express pollutant concentrations in units of the applicable emissions limit must be certified according to part 75 of this chapter. (40 CFR Part 63 Subpart UUUUU Appendix B 3.2)

Recertification Procedures
            Whenever the owner or operator makes a replacement, modification, or change to a certified CEMS that may significantly affect the ability of the system to accurately measure or record pollutant or diluent gas concentrations, stack gas flow rates, or stack gas moisture content, the owner or operator shall recertify the monitoring system. Furthermore, whenever the owner or operator makes a replacement, modification, or change to the flue gas handling system or the unit operation that may significantly change the concentration or flow profile, the owner or operator shall recertify the monitoring system. The same tests performed for the initial certification of the monitoring system shall be repeated for recertification, unless otherwise specified by the Administrator. Examples of changes that require recertification include: Replacement of a gas analyzer; complete monitoring system replacement, and changing the location or orientation of the sampling probe. (40 CFR Part 63 Subpart UUUUU Appendix B 4)
On-Going Quality Assurance Requirements

 For on-going QA test requirements for HCl and HF CEMS, implement the quality assurance/quality control procedures of Performance Specification 15 of appendix B to part 60 of this chapter as set forth in sections 5.1.1 through 5.1.3 and 5.3.2 of this appendix. (40 CFR Part 63 Subpart UUUUU Appendix B 5.1)
 On a daily basis, the permittee must assess the calibration error of the HCl or HF CEMS using either a calibration transfer standard as specified in Performance Specification 15 Section 10.1 which references Section 4.5 of the FTIR Protocol or a HCl and/or HF calibration gas at a concentration no greater than two times the level corresponding to the applicable emission limit. A calibration transfer standard is a substitute calibration compound chosen to ensure that the FTIR is performing well at the wavelength regions used for analysis of the target analytes. The measured concentration of the calibration transfer standard or HCl and/or HF calibration gas results must agree within +- 5 percent of the reference gas value after correction for differences in pressure. (40 CFR Part 63 Subpart UUUUU Appendix B 5.1.1)
 On a quarterly basis, the permittee must conduct a gas audit of the HCl and/or HF CEMS as described in section 3.1.1 of this appendix. For the purposes of this appendix, "quarterly" means once every "QA operating quarter" (as defined in section 3.1.20 of appendix A to this subpart). The permittee has the option to use HCl gas in lieu of HF gas for conducting this audit on an HF CEMS. To the extent practicable, perform consecutive quarterly gas audits at least 30 days apart. The initial quarterly audit is due in the first QA operating quarter following the calendar quarter in which certification testing of the CEMS is successfully completed. Up to three consecutive exemptions from the quarterly audit requirement are allowed for "non-QA operating quarters" ( i.e., calendar quarters in which there are less than 168 unit or stack operating hours). However, no more than four consecutive calendar quarters may elapse without performing a gas audit, except as otherwise provided in section <IP_ADDRESS>.1 of this appendix. (40 CFR Part 63 Subpart UUUUU Appendix B 5.1.2)
 The permittee must perform an annual relative accuracy test audit or RATA of the HCl or HF CEMS as described in section 3.1.2 of this appendix. Perform the RATA at normal load. For the purposes of this appendix, "annual" means once every four "QA operating quarters" (as defined in section 3.1.20 of appendix A to this subpart). The first annual RATA is due within four QA operating quarters following the calendar quarter in which the initial certification testing of the HCl or HF CEMS is successfully completed. The provisions in section <IP_ADDRESS> of appendix A to this subpart pertaining to RATA deadline extensions also apply. (40 CFR Part 63 Subpart UUUUU Appendix B 5.1.3)
 Stack gas flow rate, diluent gas, and moisture monitoring systems must meet the applicable on-going QA test requirements of part 75 of this chapter. (40 CFR Part 63 Subpart UUUUU Appendix B 5.2)
 Data Validation. (40 CFR Part 63 Subpart UUUUU Appendix B 5.3)
 Out-of-Control Periods . A HCl or HF CEMS that is used to provide data under this appendix is considered to be out-of-control, and data from the CEMS may not be reported as quality-assured, when any acceptance criteria for a required QA test is not met. The HCl or HF CEMS is also considered to be out-of-control when a required QA test is not performed on schedule or within an allotted grace period. To end an out-of-control period, the QA test that was either failed or not done on time must be performed and passed. Out-of-control periods are counted as hours of monitoring system downtime. (40 CFR Part 63 Subpart UUUUU Appendix B 5.3.1)
 Grace Periods . For the purposes of this appendix, a "grace period" is defined as a specified number of unit or stack operating hours after the deadline for a required quality-assurance test of a continuous monitor has passed, in which the test may be performed and passed without loss of data. (40 CFR Part 63 Subpart UUUUU Appendix B 5.3.2)
 For the flow rate, diluent gas, and moisture monitoring systems described in section 5.2 of this appendix, a 168 unit or stack operating hour grace period is available for quarterly linearity checks, and a 720 unit or stack operating hour grace period is available for RATAs, as provided, respectively, in sections 2.2.4 and 2.3.3 of appendix B to part 75 of this chapter. (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 For the purposes of this appendix, if the deadline for a required gas audit or RATA of a HCl or HF CEMS cannot be met due to circumstances beyond the control of the owner or operator: (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 A 168 unit or stack operating hour grace period is available in which to perform the gas audit; or
 A 720 unit or stack operating hour grace period is available in which to perform the RATA.
 If a required QA test is performed during a grace period, the deadline for the next test shall be determined as follows: (40 CFR Part 63 Subpart UUUUU Appendix B <IP_ADDRESS>)
 For a gas audit or RATA of the monitoring systems described in section 5.1 of this appendix, determine the deadline for the next gas audit or RATA (as applicable) in accordance with section 2.2.4(b) or 2.3.3(d) of appendix B to part 75 of this chapter; treat a gas audit in the same manner as a linearity check.
 For the gas audit of a HCl or HF CEMS, the grace period test only satisfies the audit requirement for the calendar quarter in which the test was originally due. If the calendar quarter in which the grace period audit is performed is a QA operating quarter, an additional gas audit is required for that quarter.
 For the RATA of a HCl or HF CEMS, the next RATA is due within three QA operating quarters after the calendar quarter in which the grace period test is performed.
 Conditional Data Validation. For recertification and diagnostic testing of the monitoring systems that are used to provide data under this appendix, and for the required QA tests when non-redundant backup monitoring systems or temporary like-kind replacement analyzers are brought into service, the conditional data validation provisions in §§75.20(b)(3)(ii) through (b)(3)(ix) of this chapter may be used to avoid or minimize data loss. The allotted window of time to complete calibration tests and RATAs shall be as specified in §75.20(b)(3)(iv) of this chapter; the allotted window of time to complete a gas audit shall be the same as for a linearity check ( i.e., 168 unit or stack operating hours). (40 CFR Part 63 Subpart UUUUU Appendix B 5.3.4)

Missing Data Requirements
            For the purposes of this appendix, the owner or operator of an affected unit shall not substitute for missing data from HCl or HF CEMS. Any process operating hour for which quality-assured HCl or HF concentration data are not obtained is counted as an hour of monitoring system downtime. (40 CFR Part 63 Subpart UUUUU Appendix B 6)
Bias Adjustment
            Bias adjustment of hourly emissions data from a HCl or HF CEMS is not required. (40 CFR Part 63 Subpart UUUUU Appendix B 7)
QA/QC Program Requirements - the owner or operator shall develop and implement a quality assurance/quality control (QA/QC) program for the HCl and/or HF CEMS that are used to provide data under this subpart. At a minimum, the program shall include a written plan that describes in detail (or that refers to separate documents containing) complete, step-by-step procedures and operations for the most important QA/QC activities. Electronic storage of the QA/QC plan is permissible, provided that the information can be made available in hard copy to auditors and inspectors. The QA/QC program requirements for the other monitoring systems described in section 5.2 of this appendix are specified in section 1 of appendix B to part 75 of this chapter.

Multiply the HCl concentration value (ppm) by 9.43 x 10[−8]to convert it to lb/scf, for use in the applicable Method 19 equation. For HF, the conversion constant from ppm to lb/scf is 5.18 x 10[−8]. (40 CFR Part 63 Subpart UUUUU Appendix B 9.3.1)
 For electrical output-based emission rates, first calculate the HCl or HF mass emission rate (lb/h), using an equation that has the general form of Equation A - 2 or A - 3 in appendix A to this subpart (as applicable), replacing the value of K with 9.43 x 10[−8]lb/scf-ppm (for HCl) or 5.18 x 10[−8](for HF) and defining Chas the hourly average HCl or HF concentration in ppm. Then, use Equation A - 4 in appendix A to this subpart to calculate the HCl or HF emission rate in lb/GWh.
