• Thank you to the 487 facilities that have submitted their Emissions Inventory reports for 2020! That is 87% of all the reports. We appreciate your hard work in completing your inventories, especially those of you who made the switch from a summary-only to a detailed report. 
  • We are working our way through Quality Control of the reports, you may receive an email from us with questions. Otherwise you are done until your next reporting cycle.
  • If you are one of the 70 facilities that has yet to submit their inventory in SLEIS, we encourage you to do so as soon as possible. We are happy to help! Please contact Catherine WilliamsCate Youatt, or Sally Lloyd for assistance.
New Approval Order Fees Coming in 2022
Beginning in 2022, per the new fee schedule authorized by the Utah State Legislature, the Utah Division of Air Quality (DAQ) will charge an annual fee to sources that have an air quality permit (Approval Order). The fee will be based on the source's total potential to emit. The DAQ will send out invoices for this fee at the beginning of 2022. The amount of the fee for the category of emissions is listed in the table below:
Any questions regarding this fee can be directed to Alan Humpherys at (385) 306-6520 or [email protected].
Fugitive Dust Control Requirements
Fugitive dust is particles of soil, ash, coal, minerals, etc., which become airborne due to wind or manmade activities like unpaved haul roads or construction and demolition activities. This dust contributes particulate matter (PM) emissions to the atmosphere, and must be minimized in order to meet National Ambient Air Quality Standards (NAAQS). The regulations described below are for the following areas of the state:
  • all regions of Salt Lake and Davis counties
  • all portions of the Cache Valley
  • all regions in Weber and Utah counties west of the Wasatch mountain range
  • in Box Elder County, from the Wasatch mountain range west to the Promontory mountain range and south of Portage
  • in Tooele County, from the northernmost part of the Oquirrh mountain range to the northernmost part of the Stansbury mountain range and north of Route 199.
Visible Emissions

Fugitive dust is limited to an opacity of 20% or less on-site, and 10% or less at the property boundary. Opacity is a measurement of how much visibility is obscured by a plume of dust. For example, if a plume of dust obscures 20% of the view in the background, the visible emissions from the dust plume is 20% opacity.
Learn more about how visible emissions are measured here
Fugitive Dust Control Plans

In addition to opacity limits, any source ¼ acre or greater in size is required to submit a Fugitive Dust Control Plan (FDCP) to the Utah DAQ. The FDCP is required to help sources minimize the amount of fugitive dust generated on-site. A source is required to submit a FDCP prior to initial construction or operation and prior to any modifications made on-site that effect fugitive dust emissions. The FDCP can be completed online here
Roadways
Any person whose activities result in fugitive dust from a road shall minimize fugitive dust to the maximum extent possible. Any person who deposits materials that may create fugitive dust on a public or private paved road shall clean the road promptly. Any person responsible for construction or maintenance of any existing or new road or having right-of- way easement or possessing the right to use a road shall minimize fugitive dust to the maximum extent possible. This includes site entrances and exits for vehicles.
All areas in the state not listed above are regulated by the statewide fugitive dust rules.
