With 2024 quickly approaching, it’s time to start thinking about emissions inventory reporting. Oklahoma Department of Environmental Quality (DEQ) requires that all major sources and many minor sources submit their emissions inventories annually for the previous year. Reporting year 2023 (RY2023) is a
National Emissions Inventory (NEI) reporting year, occurring every three years, which means that most of the Permit By Rule (PBR) facilities will need to report as well.
PBR facilities in Oklahoma are allowed to report on a three-year cycle, in line with NEI reporting, or a six-year cycle if actual emissions are below 5 tons per year (tpy) for each regulated pollutant. Therefore, ALL facilities with an air permit will be open for reporting for RY2023 using the
State & Local Emissions Inventory System (SLEIS), DEQ’s online emissions reporting program. If your company has any PBRs, this could mean that the number of facilities that you report may significantly increase and therefore present a challenge to submit before the deadline of April 1, 2024. As a reminder, the Oklahoma-specific SLEIS is one of the few that offers batch processing, which can cut your inventory preparation time in half if you have a significant number of existing facilities.
This report focuses on emissions to the atmosphere of any regulated pollutant as defined by the DEQ in OAC 252:100, Appendix P. This includes criteria pollutants, such as oxides of nitrogen (NOX) and carbon monoxide (CO), hazardous air pollutants (HAPs), and state-specific toxic air contaminants, such as ammonia. Emissions from mobile and temporary sources on your site are also required to be included.
Since all facilities will be open for reporting, and since reported data will be included in the NEI, RY2023 is the perfect year to ensure that you are consistently and accurately reporting data for your facilities. Even if your PBR facilities are on a six-year reporting cycle, it can be beneficial to report every three years to ensure that your fees are being calculated from the most recent accurate emissions data.
The annual operating fees are invoiced each year for the actual emissions from two years ago (even if the company was not the current owner). Fees are issued for each pollutant (excluding CO) up to 4,000 tpy. The fee for minor sources has been updated to $36.50/ton starting with invoices sent in July 2024 and will be subsequently increased each year based on the Consumer Price Index. The fee for Part 70 sources has been $32.30/ton plus Consumer Price Index since 2008.
