| Pressure relief valve testing, calibration of analytical
equipment; instrumentation/analyzer maintenance; replacement of analyzer
filters and screens.
(4) Engine/compressor startups associated with preventative
system shutdown activities have the option to be authorized as part
of typical operations if:
(A) prior to operation, alternative operating scenarios
to divert gas or liquid streams are registered and certified with
all supporting documentation;
(B) engine/compressor shutdowns shall result in no
greater than 4 lb/hr of natural gas emissions; and
(C) emissions which result from the subsequent compressor
startup activities are controlled to a minimum of 98% efficiency for
VOC and H2S.
(j) Records, sampling, and monitoring. The following
records shall be maintained at a site in written or electronic form
and be readily available to the agency or local air pollution control
program with jurisdiction upon request. All required records must
be kept at the facility site. If the facility normally operates unattended,
records must be maintained at an office within Texas having day-to-day
operational control of the plant site. Other requirements, including
but not limited to, federal recordkeeping or testing requirements,
can be used to demonstrate compliance if the other requirements are
at least as stringent as the associated requirements in the Tables
7 and 8 in subsection (m) of this section. Any documentation that
is already being kept for other purposes will suffice for demonstrating
requirements. If a control or method is not relied upon for emission
reductions, then the associated sampling, monitoring, and records
are not applicable.
(1) Sampling and demonstrations of compliance shall
include the requirements listed in Table 7 in subsection (m) of this
section.
(2) Monitoring and records for demonstrations of compliance
shall include the requirements listed in Table 8 in subsection (m)
of this section.
(k) Emission limits based on impacts evaluation.
(1) All impacts evaluations must be completed on a
contaminant-by-contaminant basis for any net emissions increases resulting
from a project and must meet the following as appropriate:
(A) Compliance with state or federal ambient air standards
shall be demonstrated for nitrogen dioxide (NO2),
SO2, and H2S
at any property-line within 1/4 mile or 1/2 mile of a project under
subsection (g) (Level 1) or subsection (h) (Level 2) of this section,
respectively.
(B) Compliance with hourly ESLs for benzene and annual
ESL for benzene, shall be demonstrated at the nearest receptor within
1/4 mile or 1/2 mile of a project under subsection (g) (Level 1) or
subsection (h) (Level 2) of this section, respectively.
(2) Distance measurements shall be determined using
the following.
(A) For each facility or group of facilities, the shortest
corresponding distance from any emission point, vent, or fugitive
component to the nearest receptor must be used with the appropriate
compliance determination method with the published ESLs as found through
the TCEQ internet Web page.
(B) For each facility or group of facilities, the shortest
corresponding distance from any emission point, vent, or fugitive
component to the nearest property line must be used with the appropriate
compliance determination method with any applicable state or federal
ambient air quality standard.
(3) Impacts evaluations are not required under the
following cases:
(A) If there is no receptor within 1/4 mile of a Level
1 registration, or 1/2 mile of a Level 2 registration, no further
ESL review is required.
(B) If there is no property line within 1/4 mile of
a Level 1 registration, or 1/2 mile of a Level 2 registration, no
further ambient air quality standard review is required.
(C) If the project total emissions are less than any
of the following rates, no additional analysis or demonstration of
the specified air contaminant is required:
Attached Graphic
(4) Evaluation of emissions shall meet the following.
(A) For all evaluations of NOX to
NO2, a conversion factor of 0.20 for
4-stroke rich and lean-burn engines and 0.50 for 2-stroke lean-burn
engines may be used.
(B) The maximum predicted concentration or rate at
the property boundary or receptor, whichever is appropriate, must
not exceed a state or federal ambient air standard or ESL.
(5) The impacts analysis shall be based on the following
facility emissions.
(A) The following shall be met for ESL reviews:
(i) If a project's air contaminant maximum predicted
concentrations are equal to or less than 10% of the appropriate ESL,
no further review is required.
(ii) If a project's air contaminant maximum predicted
concentrations combined with project increases for that contaminant
over a 60-month period after the effective date of this revised section
are equal to or less than 25% of the appropriate ESL, no further review
is required.
(iii) In all other cases, all facility emissions at
an OGS, regardless of authorization type, located within 1/4 mile
of a project requiring registration under this section shall be evaluated.
(B) The following shall be met for state and federal
ambient air quality standard reviews:
(i) If a project's air contaminant maximum predicted
concentrations are equal to or less than the significant impact level
(also known as de minimis impact in
Chapter 101 of this title (relating to General Air Quality Rules)),
no further review is required;
(ii) In all other cases, all facility emissions at
an OGS, regardless of authorization type, located within 1/4 mile
of a project requiring registration under this section shall be evaluated.
(6) Evaluation must comply with one of the methods
listed with no changes or exceptions.
(A) Tables.
(i) Emission impact Tables 2 - 5F in subsection (m)
of this section, may be used in accordance with the limits and descriptions
in Table 1 in subsection (m) of this section.
(ii) Values in Tables 2 - 5F in subsection (m) of this
section may be used with linear interpolation between height and distance
points. A distance of less than 50 feet or greater than 5,500 feet
may not be used. Release heights may not be extrapolated beyond the
limits of any table and instead the minimum or maximum height will
be used. If distances and release heights are not interpolated, the
next lowest height and lesser distances shall be used for determination
of maximum acceptable emissions. All facilities exempted from the
distance to the property line restriction in subsection (e)(2) of
this section must use 50 feet as the distance to the property line
for those ambient standards based on property line.
(B) Screening Modeling. A screening model may be used
to demonstrate acceptable emissions from an OGS under this section
if all of the parameters in the screening modeling protocol provided
by the commission are met.
(C) Dispersion Modeling. A refined dispersion model
may be used to demonstrate acceptable emissions from an OGS under
this section if all of the parameters in the refined dispersion modeling
protocol provided by the commission are met.
(l) The requirements in this subsection are applicable
to new and modified facilities except those specified in subsection
(a)(1) of this section. Any oil or gas production facility, carbon
dioxide separation facility, or oil or gas pipeline facility consisting
of one or more tanks, separators, dehydration units, free water knockouts,
gunbarrels, heater treaters, natural gas liquids recovery units, or
gas sweetening and other gas conditioning facilities, including sulfur
recovery units at facilities conditioning produced gas containing
less than two long tons per day of sulfur compounds as sulfur are
permitted by rule, provided that the following conditions of this
subsection are met. This subsection applies only to those facilities
named which handle gases and liquids associated with the production,
conditioning, processing, and pipeline transfer of fluids found in
geologic formations beneath the earth's surface.
(1) Compressors and flares shall meet the requirements
of §106.492 and §106.512 of this title (relating to Flares;
and Stationary Engines and Turbines, respectively). Oil and gas facilities
which are authorized under historical standard exemptions and remain
unchanged maintain that authorization and the remainder of this subsection
does not apply.
