(a) Monitoring requirements. The owner or operator
shall continuously monitor, at a point prior to the manifold that
directs gases to the Acid Gas Flare (EPN FLR1) or Acid Gas incinerator
(EPN INCIN1), the gases routed to Acid Gas Flare (EPN FLR1) or Acid
Gas Incinerator (EPN INCIN1) by using the following:
(1) monitor at a point the sulfur content of the gas
stream as follows:
(A) using a separate dedicated analyzer capable of
accurately measuring and recording total sulfur (including sulfur
dioxide (SO2), hydrogen sulfide (H2S), and organic sulfur compounds levels) with
an accuracy of ±5% on a continuous basis, the sulfur concentration
must be determined in accordance 40 Code of Federal Regulations (CFR) §60.107a(e)(1)
regardless of whether these requirements are otherwise applicable
or exempt the flare or incinerator, and hourly SO2 emissions
must be determined using the following equation; or

(B) using a separate dedicated analyzer capable of
accurately measuring and recording H2S
to an accuracy of ±5% on a continuous basis, determine the
H2S concentration in the flared gas stream,
derive an inlet flare or incinerator gas total sulfur concentration
for each monitored hourly H2S concentration
in accordance 40 CFR §60.107a(e)(2) methodology regardless of
whether these requirements are otherwise applicable or exempt the
flare or incinerator, and calculate the SO2 emissions
from the flare and the incinerator for each operating hour that either
is operated using the following equation:
Attached Graphic
(C) a totalizing gas flow meter with an accuracy of ±5%
that is installed, calibrated, maintained, and operated according
to per the manufacturer's specifications directions to continuously
measure and record the volume of gas directed to the Acid Gas Flare
(EPN FLR1) or Acid Gas Incinerator (EPN INCIN1); and
(D) monitor the temperature of gases routed to the
flare or incinerator using a temperature measurement device with an
accuracy of ±1%; the inlet flare gas temperature measurement
device must be installed, calibrated, maintained, and operated according
to the manufacturer's recommendations and specifications.
(2) In lieu of the monitoring requirements of §112.213(a)(1)
of this subsection, the owner or operator may install, calibrate,
and maintain a continuous emissions monitoring system to monitor exhaust
SO2 from the Acid Gas Incinerator (EPN
INCIN1) in accordance with the requirements of 40 CFR §60.13,
40 CFR Part 60, Appendix B, Performance Specification 2 and 6, for
SO2, and 40 CFR Part 60, Appendix F,
quality assurance procedures;
(3) Continuous monitoring data collected in accordance
with requirements in this subsection must undergo an appropriate quality
assurance and quality control process and be validated for at least
95% of the time that the monitored emission point has emissions; an
owner or operator must utilize an appropriate data substitution process
based on the most accurate methodology available, which is at least
equivalent to engineering judgment, to obtain all missing or invalidated
monitoring data for the remaining period the monitored emission point
has emissions.
(4) Minor modifications to monitoring methods may be
approved by the executive director. Monitoring methods other than
those specified in this section may be used if approved by the executive
director and validated by 40 CFR Part 63, Appendix A, Test Method
301. For the purposes of this subsection, substitute "executive director"
in each place that Test Method 301 references "administrator." These
validation procedures may be waived by the executive director or a
different protocol may be granted for site-specific applications.
Minor modifications that may be approved under this subsection include
increases in the frequency of monitoring provided appropriate quality
assurance control, accuracy specifications, and data validation requirements
are specified and no less stringent than monitoring requirements for
a comparable EPN in this subchapter.
(b) Testing requirements.
(1) The owner of operator shall perform initial testing
for monitoring devices required by subsection (a) of this section
if documentation is not available to demonstrate initial tests have
been conducted, as well as all subsequent testing, in accordance with
the manufacturer's specifications to ensure that the required monitors
are calibrated and function properly by the compliance date in §112.218
of this title (relating to Compliance Schedules).
(2) The owner or operator shall conduct initial performance
testing by the compliance date in §112.218 of this title. During
performance testing, the owner or operator shall operate the source
at the maximum rated capacity, or as near thereto as practicable.
The owner or operator shall conduct additional performance tests on
the incinerator at least every five years after the compliance date
to ensure the accuracy of the monitors for the gas stream sent to
the incinerator or flare.
(3) The owner or operator shall conduct additional
performance testing, if requested by the executive director, in compliance
with 40 CFR §60.104a to demonstrate compliance with applicable
emission limits or standards. The notification requirements of 40
CFR §60.8(d) apply to each initial performance test and to each
subsequent performance test required by the executive director.
(4) All performance tests must be conducted using test
methods allowed in §112.213(c).
(c) Approved test methods.
(1) Tests required under paragraph (b) of this section
must be conducted using the test methods in 40 CFR Part 60, Appendices
A-1 through A-8 and Appendix B or other methods as specified in this
section, except as provided in §60.8(b).
(2) Sulfur dioxide in exhaust gases from the incinerator
during testing must be determined using United States Environmental
Protection Agency (EPA) Test Method 6 or 6C (40 CFR, Part 60, Appendix
A).
(3) Alternate test methods as approved by the executive
director and the EPA may be used.
