when vent gas containing volatile organic compounds is being routed
to the flare.
(1) Average net heating value over a one-hour block period
will be used to demonstrate compliance with the minimum net heating
value requirements.
(2) The exit velocity averaged over a one-hour block pe-
riod must be used to demonstrate compliance with the maximum exit
velocity requirements.
(e) [(ce)] An owner or operator may not use emission reduction
credits or discrete emission reduction credits in order to demonstrate
compliance with this division.
115.725. Monitoring and Testing Requirements.
(a) Except for pressure relief valves as defined in 115.10 of
this title (relating to Definitions), each [Each] vent gas stream that is not
controlled by a flare at an account must be tested by applying the ap-
propriate reference method tests and procedures specified in 115.125
of this title (relating to Testing Requirements) to establish maximum
potential highly-reactive volatile organic compound (HRVOC) hourly
emission data expected during any operation not defined as an emis-
sions event or a scheduled maintenance, startup, or shutdown activ-
ity under 101.1 of this title (relating to Definitions). The data shall
be used in accordance with the test plan required under 115.726 of
this title (relating to Recordkeeping and Reporting Requirements) to
demonstrate compliance with the control requirement of 115.722(a)
- (c) [41 5722(a)] of this title (relating to Site-wide Cap and Control
Requirements). For cyclic or batch processes, the HRVOC emissions
shall be considered as zero during non-operational periods other than
startup, shutdown, or maintenance activities.
(1) For each uncontrolled vent subject to the requirements
of this subsection, the owner or operator shall:
(A) select an operational parameter or parameters that
directly correlates to the HRVOC emissions from the vent;
(B) install, calibrate, maintain, and operate according to
manufacturer's recommendations, a continuous monitoring system to
monitor and record the parameter or parameters selected under sub-
paragraph (A) of this paragraph; and
(C) establish operating limits for the selected parameter
or parameters as the hourly average of the parameter or parameters
during the HRVOC emission test required under this subsection.
(2) For each vent subject to the requirements of this subsec-
tion that is controlled by a control device other than a flare, the owner
or operator shall:
(A) select an operational parameter or parameters that
directly correlates to the HRVOC emissions directed to the control de-
vice;
(B) select an operational parameter or parameters of the
control device that directly correlates to the control efficiency of the
control device;
(C) install, calibrate, maintain, and operate according
to manufacturer recommendations, continuous monitoring systems to
monitor and record the parameters selected under subparagraphs (A)
and (B) of this paragraph; and
(D) establish operating limits for the selected parame-
ters required under subparagraphs (A) and (B) of this paragraph as the
hourly averages of the parameters during the HRVOC emission test re-
quired under this subsection.(3) To demonstrate compliance with the control require-
ments of 115.722(a) - (c) of this title during emission events and
scheduled startup, shutdown, and maintenance activities, the owner or
operator shall determine the HRVOC emissions from each vent using
one of the following:
(A) Testing using the appropriate reference methods
and procedures specified in this section; or
(B) Process knowledge and engineering calculations. If
process knowledge and engineering calculations are used to determine
HRVOC emissions during emission events and scheduled startup, shut-
down, and maintenance activities, the monitoring plans required under
paragraph (4) of this subsection must also include all process informa-
tion and calculations used to calculate the HRVOC emissions.
(4) The owner or operator shall develop, implement, and
follow a written monitoring plan for the continuous monitoring sys-
tems required in paragraphs (1) and (2) of this subsection prior to per-
forming the monitoring and testing under this subsection. Upon written
request by the executive director, the monitoring plans shall be submit-
ted within 30 days for review. The executive director may require ad-
ditional or alternative monitoring requirements. At a minimum, moni-
toring plans shall include:
(A) specifications for all monitors used in the continu-
ous monitoring systems;
(B) process and control device information supporting
the selection of parameters;
(C) actual testing or manufacturer data documenting the
control efficiency of the control device; and
(D) schedule of quarterly inspections of the continuous
monitoring systems to insure proper operation;
(5) After the initial HRVOC emission test required under
this subsection, the owner or operator may perform additional emis-
sion testing to update the data used to demonstrate compliance with the
control requirements of 115.722(a) - (c) of this title. Test plans for ad-
ditional testing must be submitted to the executive director at least 45
days prior to testing.
(6) Testing using the appropriate reference methods and
procedures specified in 115.125 of this title that was conducted be-
fore approval of the test plan required under 115.726(a) of this title
may be used in lieu of conducting the testing specified in this subsec-
tion, provided that:
(A) the owner or operator of the affected source obtains
approval for the testing report and data from the executive director; and
(B) the testing establishes maximum potential HRVOC
emissions data expected during any operation that is not defined as
an emissions event or a scheduled maintenance, startup, or shutdown
activity under 101.1 of this title.
(C) if the monitoring system required under paragraphs
(1) or (2) of this subsection was not installed at the time of testing, the
monitoring plan required under paragraph (4) of this subsection must
include sufficient documentation to demonstrate that the monitoring
system accurately reflects the parameter operating limits established
during testing. If the executive director approves the prior testing un-
der this paragraph, then the owner or operator shall comply with the
monitoring system and written monitoring plan requirements of this
subsection by no later than the compliance schedule in 115.729 of
this title (relating to Counties and Compliance Schedules) instead of
the time required in paragraph (4) of this subsection.29 TexReg 6552 July 9, 2004 Texas Register
