However, the emissions inventory shall be reported separately for each AI. C. The owner or operator of any facility meeting the applicability criteria in Subparagraph A.1.a of this Section and located in any parish listed as a nonattainment area in LAC 33:III.918.B, Tables 1-6, but redesignated by EPA as an attainment area after June 1, 2011, or adjoins a nonattainment area redesignated by EPA as an attainment area after June 1, 2011, shall continue to be subject to Subparagraph A.1.a of this Section until otherwise directed by the department. D. Reserved. E. Definitions. For the purposes of this Section, the terms below will have the meaning given herein. Actual Emissions—a calculation, measurement, or estimate, in accordance with Subsection G of this Section, of the amount of a pollutant actually emitted during a calendar year or other period of time. Agency Interest (AI)—any entity that is being regulated or is of interest to the department. Conceptually, an agency interest can be a site, facility, mobile source, area source, a person, or an organization. Attainment Area—an area of the state that is not listed as a nonattainment area by the U.S. Environmental Protection Agency. Certified—the status of an emissions inventory once the department has received both the emissions inventory and the certification statement required by this Section. Contiguous Facilities—facilities under common control separated by 0.25 miles or less. Control Efficiency—the percentage by which a control system or technique reduces the emissions from a source. Control System—a combination of one or more capture system(s) and control device(s) working in concert to reduce discharges of pollutants to the ambient air. Emissions Factor—the ratio relating emissions of a specific pollutant to an activity or material throughput level. Facility—all emissions sources from stationary point sources, as defined in LAC 33:III.605, under common control on contiguous property. NOTE: A facility can be one or more AIs, and each AI must comply individually with Subsection C of this Section. Flash Gas Emissions—emissions from depressurization of crude oil or condensate when it is transferred from a higher pressure to a lower pressure tank, reservoir, or other type of container. Fugitive Emissions—emissions that do not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening. Mobile Source—a motor vehicle, nonroad engine, or nonroad vehicle where: a. a motor vehicle is any self-propelled vehicle used to carry people or property on a street or highway; b. a nonroad engine is an internal combustion engine (including the fuel system) that is not used in a motor vehicle or a vehicle used solely for competition, and that is not affected by sections 111 or 202 of the CAA; and c. a nonroad vehicle is a vehicle that is run by a nonroad engine and is not a motor vehicle or a vehicle used solely for competition. National Ambient Air Quality Standard (NAAQS)—a standard established in accordance with section 109 of the CAA, including but not limited to, standards for carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone, particulate matter (PM2.5 and PM10), and sulfur dioxide (SO2). Nonattainment Area—an area (parish or group of parishes) that has been declared by the administrative authority to be not in compliance with a federal national ambient air quality standard and that is listed in the Federal Register as a nonattainment area. Nonpoint Sources (previously known as area sources)—collectively represent individual sources that have not been inventoried as specific point or mobile sources. These individual sources treated collectively as nonpoint sources are typically too small, numerous, or difficult to inventory using the methods for the other classes of sources. Ozone Season—except as provided in LAC 33:III.2202, the period from May 1 to September 30, inclusively, of each year. Process—an operation or function by a source that produces emissions, characterized by a Source Classification Code (SCC). Release Point—the point where emissions from one or more processes are released into the atmosphere. Reporting Period—the time frame during the reporting year for which emissions are being reported. Reporting Year—the year for which an emissions inventory is being submitted. Routine Operations—operations, not including any start-up/shutdown emissions, that are authorized and/or permitted by the department. Source—the point at which the emissions are generated, typically a piece of, or a closely related set of, equipment. F. Requirements 1. Data for emissions inventory and the certification statements shall be collected annually. The owner or operator of each facility that meets the applicability criteria of Paragraph A.1 of this Section shall submit both an emissions inventory and a certification statement required by Subparagraph F.1.c of this Section, separately for each AI, for all air pollutants for which a NAAQS has been issued and for all NAAQS precursor pollutants in a format specified by the department. a. Both the emissions inventory and the certification statement required by Subparagraph F.1.c of this Section shall include actual emissions in tons per year of ammonia (NH3), carbon monoxide (CO), lead (Pb), nitrogen oxides (NOx), particulate matter of less than 10 microns (PM10), particulate matter of less than 2.5 microns (PM2.5), sulfur dioxide (SO2), and volatile organic compounds (VOC). i. In addition to the requirements of Subsection C of this Section, the owner or operator of any facility located in the parish of Ascension, East Baton Rouge, Iberville, Livingston, St. Charles, St. James, St. John the Baptist, or West Baton Rouge is required to include actual emissions in tons per year of ethylene and propylene in both the emissions inventory and the certification statement required by Subparagraph F.1.c of this Section. ii. Supporting Information. In order to meet federal emissions inventory requirements and regulations, support modeling analyses, permit projection of future control strategies, allow the measurement of progress in reducing emissions, facilitate preparation of state implementation plans, provide data for setting baselines for future planning, and for answering public requests for information, the emissions inventory shall include, but is not limited to, the required information listed in the following table. The emissions inventory shall also include all data required by the reporting system and applicable to the facility. The information provided does 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 provisions of LAC 33:III.Chapter 5 that require a permit request to initiate or increase emissions; nor does it qualify as a notice of excess emissions.

The department will post a notice on the department’s website (www.deq.louisiana.gov) advising of any planned changes in required data elements or reporting format, so that entities subject to reporting requirements under this Section will be able to make the necessary adjustments. G. 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 EPA’s Compilation of Air Pollution Emission Factors (AP-42), calculations published in engineering journals, and/or EPA or department-approved estimation methodologies. H. 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. I. Fees. The annual emissions inventory will be used to assess the criteria pollutant annual fee in accordance with LAC 33:III.223.
