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 owner or operator of any facility located in a parish that adjoins a parish designated by EPA as a nonattainment area or within a nonattainment area after June 1, 2011, and that meets the applicability criteria in Subparagraph A.1.a of this Section, shall submit both an emissions inventory and the certification statement required by Subparagraph F.1.c of this Section to the Office of Environmental Services by April 30 of the year following the first full calendar year of the nonattainment designation by EPA, unless otherwise directed by the department.

iii. The owner or operator of any facility that has a portable source permit in accordance with LAC 33:III.513 and meets the applicability criteria in Paragraph A.1 of this Section shall submit both an emissions inventory and the certification statement required by Subparagraph F.1.c of this Section for the entire period of ownership or operatorship during the reporting year.

2. The reporting period of both the emissions inventory and the certification statement required by Subparagraph F.1.c of this Section, shall coincide with the period of ownership or operatorship during the reporting year. When there is a change of ownership of any facility to which this Section applies, submitted in accordance with LAC 33:III.517.G, at any time during a reporting year, each owner shall submit both an emissions inventory and certification statement required by Subparagraph F.1.c of this Section, with a start and/or end date that coincides with the date of transfer of ownership or operatorship.

3. Special Inventories. Upon request by the administrative authority, the owner or operator of any facility subject to LAC Title 33 shall file additional emissions data with the department. The request shall specify a reasonable time for response that shall not be less than 60 days from receipt of the request.

4. 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.
