Air Quality Laws and Rules

The Utah Air Conservation Act (Title 19, Chapter 2 of the Utah Code) empowers the Utah Air Quality Board to enact rules pertaining to Air Quality activities.

An administrative rule serves two purposes:

  • A properly enacted administrative rule has the binding effect of law. Therefore, a rule affects our lives as much as a statute passed by the Legislature.
  • An administrative rule informs citizens of actions a state government agency will take or how a state agency will conduct its business.

Opportunity to Participate

While administrative rules regulate and inform, they also provide opportunity for the public to participate in State decision-making; that opportunity is part of the rulemaking process. State agencies are required to accept public comment about proposed rules, notify you by mail if you have requested advance notice of rulemaking proceedings, and may also hold public hearings on proposed rules.

A summary table for the status of the current rule and SIP changes, including when the public comment period ends and when the rule or SIP change is expected to be adopted by the Board, is available for review.

Five-Year Reviews

All State agencies are required by the Utah Administrative Rulemaking Act (Title 63G, Chapter 3) to review each of their rules at least every fifth year. The five-year review must include a summary of all written comments received since the last review. The interpretation by the Legislature’s Administrative Rules Review Committee is that this includes all comments received during any amendment process, even though the Board has already considered all of those comments and responses.
