NOTICE OF PUBLIC COMMENT PERIOD AND HEARING: 2021 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 2021 is now available for public comment.

The Utah Division of Air Quality will hold a public hearing at 10 am on March 21, 2023. The hearing will be conducted virtuallymeet.google.com/ybd-bhqz-nnf.
