This change to the proposed rule clarifies that applicability for the emission inventory requirement is based on one ton of uncontrolled actual emissions of an individual criteria air pollutant. Additionally, it corrects subscript issues found throughout the rule. (EDITOR'S NOTE: The original proposed amendment upon which this change in proposed rule (CPR) was based was published in the October 1, 2017, issue of the Utah State Bulletin, on page 55. Underlining in the rule below indicates text that has been added since the publication of the proposed rule mentioned above; strike-out indicates text that has been deleted. You must view the CPR and the proposed amendment together to understand all of the changes that will be enforceable should the agency make this rule effective.)
