B. Types of Inventories
AQ255 §919.B.1;LAd34;LA021.12;AQ255;LR32:241(2/20/2006)
1. Annual Emissions Statement. Facilities as identified
in Subsection A of this Section, shall submit an original
Annual Emissions Statement (AES) and a duplicate for all
criteria pollutants for which a NAAQS has been issued and
for NAAQS precursor pollutants. Except as provided in
Subparagraph B.2.d of this Section, the AES shall consist
of an inventory of actual emissions and the allowable
(permitted) emissions limits of VOC, NOx, CO, SO2,
Pb, PM10, PM2.5, and ammonia, and an annual Certification
Statement in accordance with Subparagraph B.5.a of this
Section. The emissions inventory may be an initial emissions
inventory for facilities submitting their first emissions
inventory, or an annual emissions inventory update for
facilities that have previously submitted an emissions
inventory. Actual emissions shall be reported for all sources
of emissions at a facility, including fugitive emissions,
flash gas emissions, insignificant sources (as defined in LAC
33 III.501.B.5, Insignificant Activities List, A. Based on Size
of Emission Rate), and excess emissions occurring during
maintenance, start-ups, shutdowns, upsets, and downtime.
For purposes of this Section, the term actual emissions is the
calculation or estimate of the actual emissions of a pollutant,
in accordance with Subsection C of this Section, for the
calendar year or other period of time if requested by the
department. Excess emissions are defined as emissions
quantities greater than normal operations. Where there is an
enforceable document, such as a permit, that establishes
allowable levels, the AES shall include the allowable
emissions level as identified in the permit Maximum
Allowable Emissions Rate Table and the allowable tons per
year.
AQ220 §919.B.2 to B.2.d;LAd34;LA021.08;AQ220;LR29:2776(12/20/2003)
2. Statewide Annual Emissions Inventory Update.
After the initial submittal of an emissions inventory facilities
as identified in Subsection A of this Section shall comply
with the following requirements.
a. An update to the emissions inventory is required
if there is a significant change in the values currently in the
emissions reporting system for operating conditions
including start-ups, shutdowns, or process changes at
the source that results in an increase or reduction in annual
emissions of an individual pollutant: VOC, NOx, CO, SO2,
Pb, PM10, PM2.5 , or ammonia. VOCs that are also toxic air
pollutants shall be considered for the purpose of determining
significant change. A significant change is defined as the
lesser of the following:
i. a 5 percent increase or decrease in the total
potential or actual emissions from the facility;
ii. a 50 ton per year increase or decrease in the
total potential or actual emissions from the facility; or
iii. a 10 ton per year increase or decrease in the
potential or actual emissions from any single emissions point
(stack, vent, or fugitive).
b. An update to the emissions inventory is required
if there is a cessation of all production processes and
termination of operations at the facility.
c. An update to the minimum data submitted in
accordance with Paragraph B.5 of this Section is required
if there is any change.
d. Unless an update is required in accordance with
Subparagraph B.2.a, b, or c of this Section, then only the
Certification Statement is required for the annual submittal.
AQ220 §919.B.3;LAd34;LA021.08;AQ220;LR29:2776(12/20/2003)
3. Ozone Nonattainment Area Requirement. Facilities
in ozone nonattainment areas that meet the applicability in
Paragraph A.1 of this Section shall submit an annual
inventory. In addition to the minimum data requirements
of Paragraph B.5 of this Section, the inventory shall consist of
actual, annual emissions and typical weekday emissions that
occur during the three-month period of greatest or most
frequent ozone exceedances. Typical weekday emissions are
defined as an average daily emissions rate that is calculated
for each week of the three-month period of greatest or most
frequent ozone exceedances. The department will indicate
in the annual instructions which three-month period has the
greatest or most frequent ozone exceedances in each ozone
nonattainrnent area.
AQ220 §919.B.4;LAd34;LA021.08;AQ220;LR29:2776(12/20/2003)
4. Special Inventories. Upon request by the
administrative authority, any facility subject to any Rule of
the Environmental Quality regulations, LAC Title 33, shall
file additional emissions data with the department. The
request shall specify a reasonable time for response, which
shall not be less than 60 days from receipt of the request.
AQ220 §919.B.5 to B.5.g.v;LAd34;LA021.08;AQ220;LR29:2776(12/20/2003)
5. Minimum Data Requirements. The minimum data
requirements for the emissions inventory are listed below.
Operating and process rate information are provided for
information only, and do not constitute permit limits.
Submittal of a report of excess emissions above allowable
limits under this regulation does not pre-empt the need for
compliance with LAC 33:III.Chapter 5 that requires a permit
request to initiate or increase emissions, nor does it qualify
as a notice of excess emissions. Format and submittal
requirements will be published annually by the department.
Any new or modified data requirements will be included in
the annual requests for updates. Any substantive changes
will be established in accordance with the Administrative
Procedure Act. Except for the annual Certification
Statement, the minimum data requirements apply to initial
submittals only. Data requirements for updates require that
only those data elements that have changed be submitted.
a. Certification Statement. A Certification
Statement, required by Section 182(a)(3)(B) of the FCAA,
shall be signed by a responsible official as defined in LAC
33:III.502.A, or a person designated by the responsible
official, and shall accompany each emissions inventory to
attest that the information contained in the inventory is true
and accurate to the best knowledge of the certifying official.
The Certification Statement shall include the full name, title,
signature, date of signature, and telephone number of the
certifying official.
b. Facility Identification Information. The facility
identification information shall include:
i. full name, physical location, and mailing
address of facility;
ii. UTM horizontal and vertical coordinates; and
iii. SIC code(s).
c. Operating Information. The operating
information shall include:
i. percentage annual throughput by season. The
four seasons will represent one calendar year. The first
season, winter, will represent January, February, and
December of the reporting year; spring will be March-May;
summer will be June-August; and fall will be September-
November;
ii. days per week during the normal operating schedule;
iii. hours per day during the normal operating schedule; and
iv. weeks per year during the normal operating schedule.
d. Process Rate Data. The process rate data shall include:
i. annual process rate (annual throughput). The
SCC prescribes the units to be used with each SCC for
annual fuel/process rate reporting;
ii. in nonattainment parishes, peak ozone season
daily process rate. The SCC prescribes the units to be used
with each SCC for peak ozone season daily process rate
reporting. Peak ozone season daily process rate is an
average of emissions from a daily operation during the peak
ozone season months; and
iii. annual average heat, ash, and sulfur
content and design capacity, where applicable.
e. Control Equipment Information. The control
equipment information shall include:
i. current primary and secondary control equipment; and
ii. current control equipment efficiency (percent).
The actual efficiency should reflect the total control
efficiency from all control equipment and include downtime
and maintenance degradation. If the actual control efficiency
is unavailable, the design efficiency or the control efficiency
limit imposed by a permit shall be used.
f. Emissions Information. The emissions information
shall include:
i. estimated actual criteria pollutant and precursor
emissions at the emissions point level, in tons per year, if
applicable, for an annual emissions rate and pounds per day
for a typical ozone season day. Actual emissions estimates
must include all emissions, i.e., upsets, downtime, fugitive
emissions, and insignificant sources;
ii. permitted criteria pollutant and precursor
emissions at the emissions point level in tons per year and in
pounds per hour;
iii. estimated emissions method;
iv. calendar year for the emissions; and
v. emissions factor (if emissions were calculated
using an emissions factor).
g. Stack Parameters. The stack parameters shall include:
i. stack height;
ii. stack diameter;
iii. exit gas temperature;
iv. exit gas velocity; and
v. exit gas flow rate.

C. Calculations. Actual measurement with continuous
emissions monitoring systems (CEMS) or approved stack
testing shall be used for reporting of emissions from an
emissions point when such data exists. In the absence of
CEMS or stack test data, emissions shall be calculated using
methods found in the most recent edition, as of December 31
of the current reporting year, of the Compilation of Air
Pollution Emission Factors (AP-42), calculations published
in engineering journals, and/or EPA or department-approved
estimation methodologies.
AQ220 §919.D; LAd34;LA021.08;AQ220;LR29:2776 (12/20/2003)
