NOTICE OF REVIEW AND STATEMENT OF CONTINUATION

Concise explanation of the particular statutory provisions under which the rule is enacted and how these provisions authorize or require the rule:

Subsection 19-2-104(1) states that the Air Quality Board may make rules "(a) regarding the control, abatement, and prevention of air pollution from all sources and the establishment of the maximum quantity of air contamination that may be emitted by any air contaminant source." The purpose of Rule R307-420 is to require emission reductions from existing sources to offset emission increases from new or modified sources of ozone precursors in Salt Lake and Davis Counties. The emission offset will minimize growth of ozone precursors to ensure that these areas will continue to maintain the ozone national ambient air quality standards.

Summary of written comments received during and since the last five-year review of the rule from interested persons supporting or opposing the rule:

No written comments have been received about this rule since its last review.

Reasoned justification for continuation of the rule, including reasons why the agency disagrees with comments in opposition to the rule, if any:

Rule R307-420 is required to minimize the growth in emissions of ozone precursors in Salt Lake and Davis Counties. This rule supports Section IX.D (Ozone Maintenance Plan) of the State Implantation Plan, incorporated by reference under Section R307-110-13. Therefore, this rule should be continued.
