    The revisions and additions to read as follows:

Appendix A to Subpart UUUUU of Part 63--Hg Monitoring Provisions

* * * * *

3. Mercury Emissions Measurement Methods

* * * * *

    <IP_ADDRESS>.1 NIST Traceability. Only NIST-certified or NIST-
traceable calibration gas standards and reagents (as defined in
paragraphs 3.1.4 and 3.1.5 of this appendix), and including, but not
limited to, Hg gas generators and Hg gas cylinders, shall be used
for the tests and procedures required under this subpart.
Calibration gases with known concentrations of Hg\0\ and
HgCl2 are required. Special reagents and equipment may be
needed to prepare the Hg\0\ and HgCl2 gas standards
(e.g., NIST-traceable solutions of HgCl2 and gas
generators equipped with mass flow controllers).
* * * * *

4. Certification and Recertification Requirements

* * * * *
    <IP_ADDRESS> 7-Day Calibration Error Test. Perform the 7-day
calibration error test on 7 consecutive source operating days, using
a zero-level gas and either a high-level or a mid-level calibration
gas standard (as defined in sections 3.1.8, 3.1.10, and 3.1.11 of
this appendix). Use a NIST-traceable elemental Hg gas standard (as
defined in section 3.1.4 of this appendix) for the test. If moisture
and/or chlorine is added to the calibration gas, the dilution effect
of the moisture and/or chlorine addition on the calibration gas
concentration must be accounted for in an appropriate manner.
Operate the Hg CEMS in its normal sampling mode during the test. The
calibrations should be approximately 24 hours apart, unless the 7-
day test is performed over non-consecutive calendar days. On each
day of the test, inject the zero-level and upscale gases in sequence
and record the analyzer responses. Pass the calibration gas through
all filters, scrubbers, conditioners, and other monitor components
used during normal sampling, and through as much of the sampling
probe as is practical. Do not make any manual adjustments to the
monitor (i.e., resetting the calibration) until after taking
measurements at both the zero and upscale concentration levels. If
automatic adjustments are made following both injections, conduct
the calibration error test such that the magnitude of the
adjustments can be determined, and use only the unadjusted analyzer
responses in the calculations. Calculate the calibration error (CE)
on each day of the test, as described in Table A-1 of this appendix.
The CE on each day of the test must either meet the main performance
specification or the alternative specification in Table A-1 of this
appendix.
* * * * *
    <IP_ADDRESS> Three-Level System Integrity Check. Perform the 3-level
system integrity check using low, mid, and high-level calibration
gas concentrations generated by a NIST-traceable source of oxidized
Hg. Follow the same basic procedure as for the linearity check. If
moisture and/or chlorine is added to the calibration gas, the
dilution effect of the moisture and/or chlorine addition on the
calibration gas concentration must be accounted for in an
appropriate manner. Calculate the system integrity error (SIE), as
described in Table A-1 of this appendix. The SIE must either meet
the main performance specification or the alternative specification
in Table A-1 of this appendix.
* * * * *
    <IP_ADDRESS> Relative Accuracy Test Audit (RATA). Perform the RATA of
the Hg CEMS at normal load. Acceptable Hg reference methods for the
RATA include ASTM D6784-02 (Reapproved 2008), ``Standard Test Method
for Elemental, Oxidized, Particle-Bound and Total Mercury in Flue
Gas Generated from Coal-Fired Stationary Sources (Ontario Hydro
Method)'' (incorporated by reference, see Sec.  63.14) and Methods
29, 30A, and 30B in appendix A-8 to part 60 of this chapter. When
Method 29 or ASTM D6784-02 is used, paired sampling trains are
required and the filterable portion of the sample need not be
included when making comparisons to the Hg CEMS results for purposes
of a RATA. To validate a Method 29 or ASTM D6784-02 test run,
calculate the relative deviation (RD) using Equation A-1 of this
section, and assess the results as follows to validate the run. The
RD must not exceed 10 percent, when the average Hg concentration is
greater than 1.0 [micro]g/dscm. If the RD specification is met, the
results of the two samples shall be averaged arithmetically.
[GRAPHIC] [TIFF OMITTED] TP17FE15.018

Where:

RD = Relative Deviation between the Hg concentrations of samples
``a'' and ``b'' (percent),
Ca = Hg concentration of Hg sample ``a'' ([micro]g/dscm),
and
Cb = Hg concentration of Hg sample ``b'' ([micro]g/dscm).
* * * * *
    <IP_ADDRESS>.2 Calculation of RATA Results. Calculate the relative
accuracy (RA) of the monitoring system, on a [micro]g/scm basis, as
described in section 12 of Performance Specification (PS) 2 in
Appendix B to part 60 of this chapter (see Equations 2-3 through 2-6
of PS2) including the option to substitute the emission limit value
(in this case the equivalent concentration) in the denominator of
Equation 2-6 in place of the average RM value when the average
emissions for the test are less than 50 percent of the applicable
emissions limit. For purposes of calculating the relative accuracy,
ensure that the reference method and monitoring system data are on a
consistent basis, either wet or dry. The CEMS must either meet the
main performance specification or the alternative specification in
Table A-1 of this appendix.

\1\ Note that [verbar]R - A[verbar] is the absolute value of the difference between the reference gas value and
  the analyzer reading. [verbar]R - Aavg[verbar] is the absolute value of the difference between the reference
  gas concentration and the average of the analyzer responses, at a particular gas level.
\2\ Use elemental Hg standards; a mid-level or high-level upscale gas may be used. The cycle time test is not
  required for Hg CEMS that use integrated batch sampling; however, those monitors must be capable of recording
  at least one Hg concentration reading every 15 minutes.
\3\ Use elemental Hg standards.
\4\ Use oxidized Hg standards.

Appendix B to Subpart UUUUU of Part 63--HCL and HF
Monitoring Provisions

* * * * *

2. Monitoring of HCL and/or HF Emissions

* * * * *
    2.1 Monitoring System Installation Requirements. Install HCl
and/or HF CEMS and any additional monitoring systems needed to
convert pollutant concentrations to units of the applicable
emissions limit in accordance with Performance Specification 15 (PS
15) of appendix B to part 60 of this chapter for extractive Fourier
Transform Infrared Spectroscopy (FTIR) continuous emissions
monitoring systems and Sec.  63.10010(a) or Performance
Specification 18 (PS 18) of appendix B to part 60 of this chapter
for HCl CEMS and Sec.  63.10010(a).
* * * * *
    2.3 FTIR Monitoring System Equipment, Supplies, Definitions, and
General Operation. The following provisions apply:
    2.3.1 PS 15, Sections 2.0, 3.0, 4.0, 5.0, 6.0, and 10.0 of
appendix B to part 60 of this chapter, or
    2.3.2 PS 18, Sections 3.0, 6.0, and 11.0 of appendix B to part
60 of this chapter.

3. Initial Certification Procedures

* * * * *
    3.1 If you choose to follow Performance Specification 15 (PS 15)
of appendix B to part 60 of this chapter, then your HCl and/or HF
CEMS must be certified according to PS 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.
* * * * *
    3.2 If you choose to follow Performance Specification 18 (PS 18)
of appendix B to part 60 of this chapter, then your HCl and/or HF
CEMS must be certified according to PS 18, sections 7.0, 8.0, 11.0,
12.0, and 13.0.
    3.3 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.
* * * * *

5. On-Going Quality Assurance Requirements

    On-going QA test requirements for HCl and HF CEMS must be
implemented as follows:
    5.1 If you choose to follow Performance Specification 15 (PS 15)
of appendix B to part 60 of this chapter, then the quality
assurance/quality control procedures of PS 15 shall apply as set
forth in sections 5.1.1 through 5.1.3 and 5.3.2 of this appendix.
* * * * *
    5.2 If you choose to follow Performance Specification PS 18 of
appendix B to part 60 of this chapter, then the quality assurance/
quality control procedures of Procedure 6 of 40 CFR part 60,
appendix F shall apply.
    5.3 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.
* * * * *
    5.4 Data Validation.
    5.4.1 Out-of-Control Periods. An 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.
    5.4.2 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.
    <IP_ADDRESS> For the flow rate, diluent gas, and moisture monitoring
systems described in section 5.3 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.
    <IP_ADDRESS> For the purposes of this appendix, if the deadline for a
required gas audit/data accuracy assessment or RATA of an HCl or HF
CEMS cannot be met due to circumstances beyond the control of the
owner or operator:
    <IP_ADDRESS>.1 A 168 unit or stack operating hour grace period is
available in which to perform the gas audit/data accuracy
assessment; or
    <IP_ADDRESS>.2 A 720 unit or stack operating hour grace period is
available in which to perform the RATA.
    <IP_ADDRESS> If a required QA test is performed during a grace
period, the deadline for the next test shall be determined as
follows:
    <IP_ADDRESS>.1 For a gas audit or RATA of the monitoring systems
required under in section 5.3 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.
    <IP_ADDRESS>.2 For the gas audit/data accuracy assessment of an 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/data accuracy assessment is required for that quarter.
    <IP_ADDRESS>.3 For the RATA of an 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.
    5.4.3 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 Sec.  75.20(b)(3)(ii) through (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 Sec.  75.20(b)(3)(iv) of this chapter; the allotted
window of time to complete a gas audit or data accuracy assessment
shall be the same as for a linearity check (i.e., 168 unit or stack
operating hours).
* * * * *

8. 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 paragraph 5.3 of this appendix are specified in
section 1 of appendix B to part 75 of this chapter.
* * * * *

10. Recordkeeping Requirements

* * * * *
    10.1.8 Certification and Quality Assurance Test Records. For the
HCl and/or HF CEMS used to provide data under this subpart at each
affected unit (or group of units monitored at a common stack),
record the following information for all required certification,
recertification, diagnostic, and quality-assurance tests:
    <IP_ADDRESS> HCl and HF CEMS.
    <IP_ADDRESS>.1 For all required daily calibrations and checks
(including calibration transfer standard tests) of the HCl or HF
CEMS, record the test dates and times, reference values and their
certification information, action levels for integrated path HCl
CEMS, HCl or HF monitor responses, and calculated calibration error
values;
    <IP_ADDRESS>.2 For quarterly gas audits of HCl or HF CEMS certified
under PS 15 of appendix B to part 60 of this chapter follow
paragraph <IP_ADDRESS>.2.1 of this appendix and for quarterly data
accuracy assessments under PS 18 of appendix B to part 60 of this
chapter follow paragraph <IP_ADDRESS>.2.2 of this appendix.
    <IP_ADDRESS>.2.1 Record the date and time of each spiked and
unspiked sample, the audit gas reference values and uncertainties.
Keep records of all calculations and data analyses required under
sections 9.1 and 12.1 of P S 15 of appendix B to part 60 of this
chapter, and the results of those calculations and analyses.
    <IP_ADDRESS>.2.2 [Reserved]
    <IP_ADDRESS>.3 For each RATA or RAA of a HCl or HF CEMS, record the
date and time of each test run, the reference method(s) used, and
the reference method and HCl or HF CEMS values. Keep records of the
data analyses and calculations used to determine the relative
accuracy.
* * * * *

11. Reporting Requirements

* * * * *
    11.4 Certification, Recertification, and Quality-Assurance Test
Reporting Requirements. Except for daily QA tests (e.g.,
calibrations and flow monitor interference checks), which are
included in each electronic quarterly emissions report, use the
ECMPS Client Tool to submit the results of all required
certification, recertification, quality-assurance, and diagnostic
tests of the monitoring systems required under this appendix
electronically, either prior to or concurrent with the relevant
quarterly electronic emissions report.
* * * * *
    11.4.2 For daily beam intensity checks for integrated path HCl
CEMS as specified by PS 18 of appendix B to part 60 of this chapter,
report:
    <IP_ADDRESS> through <IP_ADDRESS> [Reserved]
    11.4.3 For each quarterly gas audit of an HCl or HF CEMS under
Performance Specification 15, report:
    <IP_ADDRESS> Facility ID information;
    <IP_ADDRESS> Monitoring system ID number;
    <IP_ADDRESS> Type of test (e.g., quarterly gas audit);
    <IP_ADDRESS> Reason for test;
    <IP_ADDRESS> Certified audit (spike) gas concentration value (ppm);
    <IP_ADDRESS> Measured value of audit (spike) gas, including date and
time of injection;
