Louisiana Administrative Code, Title 33 ENVIRONMENTAL QUALITY, Part III Air (LAC 33:III)
Chapter 9. General Regulations on Control of Emissions and Emission Standards
Section 919. Emission Inventory
Approved by EPA January 6, 1995 (60 FR 02014) at 52.970(c)(65) effective February 6, 1995.
Emission inventory data shall be submitted to the Louisiana Department of Environmental Quality (DEQ) on magnetic media in the format specified by the Air Quality Division. Facilities with less than five point sources, may elect to submit Emission Inventory Coding (EIC) forms in lieu of the magnetic media. Facilities are defined as all emission points, fugitive, area, mobile, under common control on contiguous property. Point source is defined as the point of emission which should have a Source Classification Code. Stationary source is defined as a group of point sources. Detailed instructions are provided on an annual basis for completing and submitting emissions inventories which define requirements applicable to facilities, point sources, area sources and mobile sources.
A. Applicability. The owner or operator of the following facilities in the state of Louisiana shall submit emissions inventories to the Louisiana Department of Environmental Quality.
1. Any facility in an attainment area or unclassified area that has the potential to emit 100 tons per year (TPY) or more of any contaminant [including volatile organic compounds (VOC)] for which a National Ambient Air Quality Standard (NAAQS) has been issued or any facility in an ozone nonattainment area emitting a minimum of 10 tons per year (TPY) volatile organic compounds (VOC), 25 TPY nitrogen oxides (NOx), or 100 TPY carbon monoxide (CO), or any facility that has the potential to emit ("allowables" in a facility's permit) 50 TPY or more of VOC in an area designated as an ozone adjoining area. The designated ozone nonattainment and adjoining parishes are listed in Table 1. If either VOC or NOx is emitted at or above the minimum required reporting level, the other pollutant must be included even if it is emitted at levels below the specified cutoff.

2. Any facility defined as a major stationary source of hazardous air pollutants in Section 112(a)(1) of the Federal Clean Air Act (FCAA).
3. In Louisiana, the following facility classes or categories are exempted: None.
B. Types of Inventories
1. Annual Emissions Statement (AES). Stationary sources as identified in Subsection A of this Section, shall submit an Annual Emissions Statement (AES) for all criteria pollutant including VOC and hazardous air pollutants. The AES shall consist of an inventory of actual emissions and allowable (permitted) emissions of VOC, NOx, CO, sulfur dioxide (SO2), lead (Pb), and particulate matter of less than 10 microns in diameter (PM10) from stationary sources and emissions of all hazardous air pollutants identified in Section 112(b) of the FCAA, and the certifying statement. Methane, ethane, and CFCs are not included in VOCs and are not reportable. The emission inventory may be an initial emission inventory (IEI) for facilities submitting their first emission inventory or an annual emission inventory update (AEIU) for facilities which have previously submitted an emission inventory. For purposes of this Section, the term "actual emission" is the actual rate of emissions (annually and hourly) of a pollutant from an emissions unit for the calendar year or other period of time if requested by the department. Actual emission estimates shall also include fugitive emissions (i.e., waste water treatment; treatment, storage and disposal facilities; etc.) excess emissions occurring during maintenance, start-ups, shutdowns, upsets, and downtime to parallel the documentation of these events in the emission inventory and must follow emission calculations as identified in Subsection C of this Section. Excess emission is defined as an emission quantity greater than normal operations. Where there is an enforceable document, such as a permit, establishing allowable levels, the AES shall include the allowable emission level as identified in the permit Maximum Allowable Emission Rate Table.
2. Statewide Annual Emission Inventory Update. Facilities as identified in Subsection A of this Section shall submit an Annual Emission Inventory Update (AEIU) which consists of actual and allowable emissions from the facility identified in Subsection A.1 of this Section, if any of the following criteria are met:
a. AEIU are required for any facilities subject to SIP regulation if a significant change in emission rates has occurred as defined in Subsection B.2.b and c of this Section;
b. any change in the values currently in the emission reporting system for operating conditions including start-ups, shutdowns, or process changes at the source that results in a 5.0 percent or greater increase or reduction in total annual emissions of individual pollutant: VOC, NOx, CO, SO2, Pb, or PM10; VOCs that are also Hazardous Air Pollutants are to be viewed as total VOC.
c. a cessation of all production processes and termination of operations at the facility;
d. if there are no significant changes in emission rates as defined in Subsection B.2.b and c of this Section, then only the certifying statement is required for annual submittal.
3. Ozone Nonattainment Area Statement. Stationary sources in ozone nonattainment areas emitting a minimum of 10 TPY of VOC, 25 TPY of NOx, or 100 TPY of CO shall submit an annual statement. The statement shall consist of actual, annual emissions and typical weekday emissions that occur during the three-month period of greatest or most frequent ozone exceedances as published by the department in the Enforcement and Regulatory Compliance notice that is mailed out monthly from the Division of Legal Affairs and Enforcement. "Typical weekday" emissions are defined as an "average" of two actual daily emission rates (one at the lowest emission rate and one at the highest emission rate) during a seven-day period.
4. Special Inventories. Upon request by the administrative authority any person subject to any rule of the Air Quality Division 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.
5. Minimum Data Requirements. The minimum data requirements are listed below. Operating and process rate information are for the purposes of information gathering only, and do not constitute permit limits. Subsection A.1 states that submittal of a report of increased emissions above allowable limits under this regulation does not replace the need for compliance with LAC 33:III.505.A which requires a permit request to initiate or increase 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. The minimum data requirements apply to initial submittals only. Data requirements for updates require only those data elements which have changed to be submitted:
a. Certifying Statement. A certifying statement, required by Section 182(a)(3)(B) of the FCAA, is to be signed by the owner(s) or operator(s) and shall accompany each emission inventory to attest that the information contained in the inventory is true and accurate to the best knowledge of the certifying official. The certification shall include the full name, title, signature, date of signature, and telephone number of the certifying official.
b. Facility Identification Information
i. full name, physical location, and mailing address of facility;
ii. UTM horizontal and vertical coordinates
iii. SIC code(s).
c. Operating Information
i. percentage annual throughput by season. The first season (December-February) will actually encompass a two-year period. (e.g., December 1991 through February 1992). The remaining seasons (March-May, June-August, September-November) represent one calendar year (e.g., 1992);
ii. days per week during the normal operating schedule;
iii. hours per day during the normal operating schedule;
iv. hours per year during the normal operating schedule.
d. Process Rate Data
i. annual process rate (annual throughput). The AIRS facility subsystem (AFS) Source Classification Code Table prescribes the units to be used with each source classification code for annual fuel/process rate reporting;
ii. in nonattainment areas, peak ozone season daily process rate. The AIRS facility subsystem Source Classification Code Table prescribes the units to be used with each Source Classification Code for peak ozone season daily process rate reporting.
e. Control Equipment Information
i. current primary and secondary AFS control equipment identification codes;
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
i. estimated actual VOC and/or NOx emissions at the segment level, in tons per year for an annual emission rate and pounds per day for a typical ozone season day (defined as the average or typical operating day during the peak ozone season). A segment level is the amount of emissions that are attributed to each Source Classification Code. Actual emission estimates must include upsets, downtime and fugitive emissions, and must follow an "emission estimation method." Emissions will be reported as one number;
ii. AFS estimated emissions method code;
iii. calendar year for the emissions;
iv. emission factor (if emissions were calculated using an emission factor).
C. Calculations. Actual measurement with continuous emissions monitoring systems (CEMS) is the desired method of calculating emissions from a point source. In lieu of CEMS data, emissions may be calculated using methods found in the most recent edition of the Compilation of Air Pollution Emission Factors (AP-42) or calculations published in Engineering Journals. Calculations published in Engineering Journals should have prior administrative approval (assistant secretary) before use. Annual instructions will list any calculations approved from Engineering Journals.
D. After data processing and inventory update, the department will submit the revised inventory to the facility for final verification and signature. The certified inventory shall then be submitted to DEQ/AQD, within 60 days from the date of receipt of the data from the department.
E. Reporting Requirements. The AES for the 1992 Ozone Nonattainment Area Inventory shall be submitted to the department no later than March 31, 1993 unless otherwise directed. Subsequent AESs and Ozone Nonattainment Area Inventories updates shall contain emissions data from the previous calendar year and shall be due on March 31 of each year unless otherwise directed. Attainment Area Inventory shall be submitted to the department from the previous calendar year no later than March 31 of each year unless otherwise directed.
F. Enforcement. The department reserves the right to initiate formal enforcement actions, under R.S. 30:2025, for failure to submit emissions inventories as required in this Section.
