Notice of Public Comment Period and Hearing

2022 Sulfur Dioxide Milestone Report

Utah’s State Implementation Plan for Regional Haze (the Plan) adopted by the Air Quality Board on April 6, 2011, requires that Utah cooperate with New Mexico, Wyoming, and Albuquerque-Bernalillo County in producing an annual report to determine if the emissions of sulfur dioxide (SO2) from large industrial sources from the most current year are less than the emissions milestone set in the Plan. The final milestone year of the plan is 2018. The plan requires Utah to continue comparing subsequent years to the 2018 milestone to ensure that the state still meets the 2018 milestone obligation. The draft report for the calendar year 2022 is now available for public comment. 

The Utah Division of Air Quality will hold a public hearing from 1-2pm on February 26, 2024. The hearing will be conducted in person as well as virtually.

In compliance with the Americans with Disabilities Act, individuals with special needs (including auxiliary communicative aids and services) should contact the Office of Human Resources, at (801) 536-4412 (TDD 536-4414).

The public comment period begins on February 19, 2024 and closes at 5:00 p.m. on March 20, 2024.  Comments postmarked on or before that date will be accepted. Comments may be submitted by electronic mail to ccancino@utah.gov or may be mailed to:

2023 DAQ Annual Report

The Annual Report is intended to provide an overview of Utah’s air quality, as well as the Division of Air Quality’s organization, activities, and progress throughout 2023.

2-Stroke Yard Care Rule

The Division of Air Quality is examining ways of reducing ozone forming emissions in efforts to improve summertime air quality.  As a result, the Division is requesting feedback regarding a potential rule to reduce emissions from lawn and garden equipment on high ozone days.   

Learn more about the potential rule and emissions from 2-stroke yard care equipment, as well as ongoing incentive programs, at chargeyouryard.utah.gov where you can also use the “Q&A – read submitted questions” link to submit questions or comments.

Uinta Basin Emission Factor for Pumpjack Engines

The Utah Division of Air Quality (UDAQ) has collected a significant amount of emission data associated with pumpjack engines in the Uinta Basin (UB) over the past few years. The data collected indicates that the past emission inventories collected for these engines have significantly underestimated VOC emissions and overestimated NOx emissions. These underestimations are most pronounced for two-stroke lean burn engines (2SLB), which are used widely across the UB to support the operation of lift to pumpjacks. To more accurately reflect the emissions from these sources, UDAQ is proposing to establish a UB-specific emission factor to be used in the collection of the 2023 triennial national emission inventory and the Utah state oil and gas inventory collected. UDAQ would like to receive comments on this proposal for a 30 day period from November 20 to December 19, 2023. Please provide those comments or any questions to Sheila Vance at svance@utah.gov.

House Bill 220 (General Session 2023) 

House Bill 220 (General Session 2023) requires UDAQ to:

  • complete an emissions inventory of point sources that emit halogens by December 31, 2024,
  • complete an emissions reduction plan to reduce halogens by December 31, 2026, and
  • provide recommendations for a state standard limiting halogen emissions

S.B. 136 

Senate Bill 136 (General Session 2022) required UDAQ to conduct studies and provide recommendations to inform the development of a Utah-specific diesel emissions reduction framework.

2023 Utah Air Monitoring Network Plan Available for Comment

The Annual Air Monitoring Network Plan is available for review and comment.

The Utah Air Monitoring Center provides an annual review of information about the Utah air monitoring network and pollution trend.

Charge Your Yard Incentive Program

Lawn care businesses in Davis, Salt Lake, Tooele, Utah, and Weber counties can receive a discount up to $3,000 to upgrade their gas-powered leaf blowers and string trimmers to battery-powered electric equipment. Visit ChargeYourYard.utah.gov to view full eligibility requirements and to apply!

Utah Receives $1,284,587 for three community air pollution monitoring projects

The EPA has selected three Utah groups, including the Department of Environmental Quality, to receive funding to conduct air quality monitoring in communities across Davis and Salt Lake Counties. The projects are focused on communities that are underserved, historically marginalized, and overburdened by pollution.

Senate Bill 136 Status Report for Legislative Interim Committees

Through Senate Bill 136, the Utah Department of Environmental Quality is directed to conduct a study and develop a framework for a Utah-specific diesel emissions reduction program. A status report on the Department’s progress has been provided to the November legislative interim committees.

Reducing Summertime Ozone Pollution in Utah

Thank you to those who joined our meetings! For those who weren’t able to join, you can now watch the meeting recordings and view the slides. You can also review the Ozone SIP website where you can explore the interactive emissions inventory tool, and of course, submit your emission reduction ideas.

R307-401. Permit: New and Modified Sources

Due to the OAR website having problems publishing the R307-401 rule, DAQ is posting the most updated version of the rule on the DAQ website. The rule was last updated and made effective September 3, 2020.

Oil and Gas Sources – Major CAERS update!

The Centralized Air Emissions Reporting System (CAERS) updates on February 3rd. Watch the tutorial and download the new CAERS User Manual here.
