(o)(3)(i) and (ii) of this section would be counted as an event under
each of the separate criteria counts for that flare. Additionally, if a
single root cause analysis was conducted for an event that caused
multiple flares to meet the criteria in paragraph (o)(3)(i) or (ii) of
this section, that event would count as an event for each of the flares
for each criteria in paragraph (o)(3) of this section that was met
during that event. The owner or operator shall also determine the total
number of events for which a root cause and correct action analyses was
required and the analyses concluded that the root cause was a force
majeure event, as defined in this subpart.
    (7) The following events would be a violation of this emergency
flaring work practice standard.
    (i) Any flow event for which a root cause analysis was required and
the root

cause was determined to be operator error or poor maintenance.
    (ii) Two visible emissions exceedance events meeting the criteria
in paragraph (o)(3)(i) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for the
same root cause for the same equipment.
    (iii) Two flare tip velocity exceedance events meeting the criteria
in paragraph (o)(3)(ii) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for the
same root cause for the same equipment.

in paragraph (o)(3)(i) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for any
reason.

Sec.  63.670(j)(1), the gas chromatograph must also meet the
requirements of paragraphs (e)(1) through (3) of this section.
    (1) The quality assurance requirements are in table 13 of this
subpart.
    (2) The calibration gases must meet one of the following options:
    (i) The owner or operator must use a calibration gas or multiple
gases that include all of compounds listed in paragraphs (e)(2)(i)(A)
through (K) of this section that may be reasonably expected to exist in
the flare gas stream and optionally include any of the compounds listed
in paragraphs (e)(2)(i)(L) through (O) of this section. All of the
calibration gases may be combined in one cylinder. If multiple
calibration gases are necessary to cover all compounds, the owner or
operator must calibrate the instrument on all of the gases.

    (N) Propadiene (optional).
    (O) Hydrogen sulfide (optional).
    (ii) The owner or operator must use a surrogate calibration gas
consisting of hydrogen and C1 through C5 normal hydrocarbons. All of
the calibration gases may be combined in one cylinder. If multiple
calibration gases are necessary to cover all compounds, the owner or
operator must calibrate the instrument on all of the gases.
    (3) If the owner or operator chooses to use a surrogate calibration
gas under paragraph (e)(2)(ii) of this section, the owner or operator
must comply with paragraphs (e)(3)(i) and (ii) of this section.
    (i) Use the response factor for the nearest normal hydrocarbon
(i.e., n-alkane) in the calibration mixture to quantify unknown
components detected in the analysis.
    (ii) Use the response factor for n-pentane to quantify unknown

Sec.  63.1571  How and when do I conduct a performance test or other
initial compliance demonstration?

    (a) * * *
    (5) Periodic performance testing for PM or Ni. Except as provided
in paragraphs (a)(5)(i) and (ii) of this section, conduct a periodic
performance test for PM or Ni for each catalytic cracking unit at least
once every 5 years according to the requirements in Table 4 of this
subpart. You must conduct the first periodic performance test no later
than August 1, 2017.
    (i) Catalytic cracking units monitoring PM concentration with a PM
CEMS are not required to conduct a periodic PM performance test.
    (ii) Conduct a performance test annually if you comply with the
emission limits in Item 1 (NSPS subpart J) or Item 4 (Option 1a) in
Table 1 of this subpart and the PM emissions measured during the most
recent performance source test are greater than 0.80 g/kg coke burn-
off.
    (6) One-time performance testing for HCN. Conduct a performance
test for HCN from each catalytic cracking unit no later than August 1,
2017 according to the applicable requirements in paragraphs (a)(6)(i)
and (ii) of this section.
    (i) If you conducted a performance test for HCN for a specific
catalytic cracking unit between March 31, 2011 and February 1, 2016,
you may submit a request to the Administrator to use the previously
conducted performance test results to fulfill the one-time performance
test requirement for HCN for each of the catalytic cracking units
tested according to the requirements in paragraphs (a)(6)(i)(A) through
(D) of this section.
    (A) The request must include a copy of the complete source test
report, the date(s) of the performance test and the test methods used.
If available, you must also indicate whether the catalytic cracking
unit catalyst regenerator was operated in partial or complete
combustion mode during the test, the control device configuration,
including whether platinum or palladium combustion promoters were used
during the test, and the CO concentration (measured using CO CEMS or
manual test method) for each test run.
    (B) You must submit a separate request for each catalytic cracking
unit tested and you must submit each request to the Administrator no
later than March 30, 2016.
    (C) The Administrator will evaluate each request with respect to
the completeness of the request, the completeness of the submitted test
report and the appropriateness of the test methods used. The
Administrator will notify the facility within 60 days of receipt of the
request if it is approved or denied. If the Administrator fails to
respond to the facility within 60 days of receipt of the request, the
request will be automatically approved.
    (D) If the request is approved, you do not need to conduct an
additional HCN performance test. If the request is denied, you must
conduct an additional HCN performance test following the requirements
in (a)(6)(ii) of this section.
    (ii) Unless you receive approval to use a previously conducted
performance test to fulfill the one-time performance test requirement
for HCN for your catalytic cracking unit as provided in paragraph
(a)(6)(i) of this section, conduct a performance test for HCN for each
catalytic cracking unit no later than August 1, 2017 according to
following requirements:
    (A) Select sampling port location, determine volumetric flow rate,
conduct gas molecular weight analysis and measure moisture content as
specified in either Item 1 of Table 4 of this subpart or Item 1 of
Table 11 of this subpart.
    (B) Measure HCN concentration using Method 320 of appendix A of
this part. The method ASTM D6348-03 (Reapproved 2010) including Annexes
A1 through A8 (incorporated by reference--see Sec.  63.14) is an
acceptable alternative to EPA Method 320 of appendix A of this part.
The method ASTM D6348-12e1 (incorporated by reference--see Sec.  63.14)
is an acceptable alternative to EPA Method 320 of appendix A of this
part with the following two caveats:
    (1) The test plan preparation and implementation in the Annexes to
ASTM D6348-03 (Reapproved 2010), Sections A1 through A8 are mandatory;
and
    (2) In ASTM D6348-03 (Reapproved 2010) Annex A5 (Analyte Spiking
Technique), the percent (%) R must be determined for each target
analyte (Equation A5.5). In order for the test data to be acceptable
for a compound, %R must be 70% >= R <= 130%. If the %R value does not
meet this criterion for a target compound, the test data is not
acceptable for that compound and the test must be repeated for that
analyte (i.e., the sampling and/or analytical procedure should be
adjusted before a retest). The %R value for each compound must be
reported in the test report, and all field measurements must be
corrected with the calculated %R value for that compound by using the
following equation:

Reported Result = (Measured Concentration in the Stack x 100//% R.

    (C) Measure CO concentration as specified in either Item 2 or 3a of
Table 11 of this subpart.
    (D) Record and include in the test report an indication of whether
the catalytic cracking unit catalyst regenerator was operated in
partial or complete combustion mode and the control device
configuration, including whether platinum or palladium combustion
promoters were used during the test.
    (b) * * *
    (1) Performance tests shall be conducted according to the
provisions of Sec.  63.7(e) except that performance tests shall be
conducted at maximum representative operating capacity for the process.
During the performance test, you must operate the control device at
either maximum or minimum representative operating conditions for
monitored control device parameters, whichever results in lower
emission reduction. You must not conduct a performance test during
startup, shutdown, periods when the control device is bypassed or
periods when the process, monitoring equipment or control device is not
operating properly. 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 the test was conducted at
maximum representative operating capacity. Upon request, you must make
available to the Administrator such records as may be necessary to
determine the conditions of performance tests.
* * * * *
    (d) * * *
    (2) If you must meet the HAP metal emission limitations in Sec.
63.1564, you elect the option in paragraph (a)(1)(iv) in Sec.  63.1564
(Ni per coke burn-off), and you use continuous parameter monitoring
systems, you must establish an operating limit for the equilibrium
catalyst Ni concentration based on the laboratory analysis of the
equilibrium catalyst Ni concentration from the initial performance
test. * * *
* * * * *
    (4) Except as specified in paragraph (d)(3) of this section, if you
use continuous parameter monitoring systems, you may adjust one of your
monitored operating parameters (flow rate, total power and secondary
current, pressure drop, liquid-to-gas ratio) from the average of
measured values during the performance test to the maximum value (or
minimum value, if applicable) representative of worst-case operating
conditions, if necessary. This adjustment of measured values may be
done using control device design specifications, manufacturer
recommendations, or other applicable information. You must provide
supporting documentation and rationale in your Notification of
Compliance Status, demonstrating to the satisfaction of your permitting
authority, that your affected source complies with the applicable
emission limit at the operating limit based on adjusted values.

may install, operate, and maintain each continuous parameter monitoring
system in a manner consistent with the manufacturer's specifications or
other written procedures that provide adequate assurance that the
equipment will monitor accurately.
* * * * *
    (3) Each continuous parameter monitoring system must have valid
hourly average data from at least 75 percent of the hours during which
the process operated, except for BLD systems.
    (4) Each continuous parameter monitoring system must determine and
record the hourly average of all recorded readings and if applicable,
the daily average of all recorded readings for each operating day,
except for BLD systems. The daily average must cover a 24-hour period
if operation is continuous or the number of hours of operation per day
if operation is not continuous, except for BLD systems.
* * * * *
    (d) * * *
    (1) You must conduct all monitoring in continuous operation (or
collect data at all required intervals) at all times the affected
source is operating.
    (2) You may not use data recorded during required quality assurance
or control activities (including, as applicable, calibration checks and
required zero and span adjustments) for purposes of this regulation,
including data averages and calculations, for fulfilling a minimum data
availability requirement, if applicable. You must use all the data
collected during all other periods in assessing the operation of the
control device and associated control system.
