93404(b)(1)(D)
must be updated in the next required emissions report when there are physical
changes to the facility structure or emissions release locations, or if there
are substantive changes to emissions sources or operations, such as those
requiring the addition, modification, or removal of district air
permits.
(2)
Abbreviated Report Contents. Owners and operators of a
facility that qualifies for abbreviated reporting pursuant to 93421(a) or (b)
are required to report the Facility Data of 93404(a) and
93404(b)(1)(B)(5) and (6), but are not required to report the remaining
contents of 93404(b)(1). The abbreviated report must include the content listed
in 93421(a) for each qualifying activity, and any activity data specified
pursuant to 93421(b). Additional device level, process level, and emissions
level data for the facility may be provided to CARB by the local air
district.
(c)
Emissions and Sources. Annual emissions reports for a facility
must include the emissions and sources as specified in 93404(c)(1) and (2).
(1)
Emissions. For permitted
processes and devices (and unpermitted processes and devices, if emissions
reporting is required pursuant to district rules or policies), the annual
direct and fugitive emissions of the following air pollutants must be reported.
Alternatively, at the discretion of the local air district, sufficient activity
level data must be submitted for the air district to calculate such emissions.
(A) Criteria air pollutants, in units of
short tons per year. For organic gases, unless otherwise required by the local
air district, ROG, VOC, or total organic gases may be reported to satisfy this
requirement, and CARB will quantify the other two using CARB speciation
profiles. If a district has established a rule that defines ROG differently
than this article, the district may use the district rule definition to
quantify ROG. For particulate matter, emissions of
PM2.5, PM10, and total PM must be
reported, or as required by the local air district, one of the three values
must be reported and CARB will quantify the other two values using CARB
particulate matter speciation profiles.
Lead must be reported in both tons per year using
Pollutant Code 12128 and in pounds per year using Emittent ID 7439921. Ammonia
must be reported in both tons per year using Pollutant Code 42604 and pounds
per year using Emittent ID 7664417.
(B) Toxic air contaminants, as defined
herein, in units of pounds per year, except for radionuclides which must be
reported in units of curies per year. The reported toxic air contaminants must
include those chemicals that are actually emitted by the facility by permitted
processes and devices (and unpermitted processes and devices, if emissions
reporting is required pursuant to district rules or policies), based on
existing quantification methods. Reporting must include the substances
identified in the 2007 EICG, previously cited in the "Toxic air contaminants"
definition, and the substances identified in Appendix B, with reporting of the
Appendix B toxic substances phased-in as specified in Table B-1.
If at the time a substance becomes subject to reporting
per Table B-1, a listed toxic air contaminant substance is present or is used
or produced at a facility in a way that may result in airborne emissions, one
of the alternatives identified as "best available data and methods," as defined
in this article, must be used to quantify the emissions, as applicable. If an
air district determines that none of the alternatives listed would provide a
reasonable, technically justified emissions estimate, and no other method can
be determined that will provide such an estimate, then the presence of the
toxic air contaminant and the amount used or produced at the facility during
the data year must be reported without an estimated quantitative emissions
value. Purchase records, substance inventory reconciliation, direct
measurement, or other methods may be used to estimate amounts used or
produced.
(2)
Sources. Except as indicated in section
93404(c)(2)(C),
below, emissions as specified in 93404(c)(1), must be reported for the
following emissions sources:
(A) Permitted
processes and devices at the facility.
(B) Unpermitted processes and devices at the
facility, including unpermitted fugitive emissions, if at the beginning of the
data year such facility-specific emissions are required by the local air
district to be reported or if the emissions are quantified on behalf of the
facility owner or operator by the local air district.
(C)
Portable Diesel-Fueled Engines
and Devices. Except as provided in section
93404(c)(2)(D),
emissions from portable diesel-powered engines and devices (including equipment
registered under the Portable Equipment Registration Program) rated at 50
maximum rated horsepower (brake horsepower (bhp)) or above and operated at a
GHG and/or Criteria Facility (sections
93401(a) (1-2)),
regardless of equipment ownership or permit status, if the engine or device is
operated on site at any time during the data year. If local air district rules
or policies requires reporting of emissions from additional portable
diesel-fueled engines and devices, the district may require reporting for such
sources under this article.
The data of 93404(b)(1) does not need to be provided for
portable engines and devices, unless required by the local air district. The
use of best available data and methods, including the use of engineering
estimates, may be used to quantify emissions from portable engines and devices,
and the emissions data from multiple engines may be aggregated if approved by
the local air district. Alternatively, the activity data necessary to estimate
the emissions from such portable diesel-powered engines and devices shall be
reported to the district, and the district may quantify the emissions on behalf
of the facility. Reporting of emissions from such engines and devices begins
with 2022 emissions reported in 2023.
(D)
Exemptions. Device,
process, emissions, and release location data, as requested under section
93404(b)(1), do
not need to be reported for the following sources.
1. Internal combustion engines used for
irrigation pumps (including booster pumps and groundwater well pumps),
combusting diesel fuel or other fuels, at agricultural operations.
2. Open burning of fields, or open burning of
agricultural wastes or agricultural residues that is subject to burn permitting
by a local air district.
3.
Tactical support equipment (TSE).
(d)
Use of Best Available Data and
Methods. Annual emissions reports prepared pursuant to this article
must provide the emissions calculation method, the source of the reported
emissions factor, and the control efficiency, as applicable, using best
available data and methods, that are used to compute emissions of criteria air
pollutants and toxic air contaminants. If an air district calculates emissions
on behalf of a facility using activity level data provided by the facility, the
district will report the calculation methods, emission factors and other
information used to quantify emissions, using best available data and methods.
Calculation methods must identify the general methods used, such as continuous
emissions monitoring system, facility-specific emission factors, facility
source test data, emission factors provided by an air district, or U.S. EPA
emission factors. If activity data is used to calculate emissions, the reported
calculation method must include a general description of the technique used to
acquire the activity data, such as sales records, measurement devices, material
balance, throughput, or material produced used to quantify parameters to which
emission factors are applied.
(e)
Attestation. With the submitted annual report, the designated
representative for a facility subject to this article must provide an
attestation to the local air district or to CARB that he or she is authorized
by the owner or operator of the facility to submit the emissions report, and
that to the best of his or her knowledge, all information submitted by the
designated representative pursuant to this article is true, complete, and
correct.
