Five-Year Notice of Review and Statement of Continuation

DAR File No.: 35778
Filed: 02/01/2012 04:28:59 PM

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:

Section 211(m)(1) of the Clean Air Act required Utah County to implement an oxygenated gasoline program to bring it into attainment of the carbon monoxide National Ambient Air Quality Standards. Clean Air Act Section 175A(d) requires that maintenance plans assure prompt action to correct any violation of the standard that occurs after an area is redesignated to attainment, and mandatory Clean Air Act requirements such as an oxygenated fuels program must be included as contingency measures. Rule R307-301 remains in place in case the carbon monoxide health standard is violated in Provo or Ogden; in which case, an oxygenated gasoline program could be reinstated based on the trigger measures in State Implementation Plan (SIP) Subparts IX.C.6.e(5)(a) and IX.C.8.f.

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 on this rule since its last five-year review.

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

Section 211(m)(1) of the Clean Air Act required Utah County to implement an oxygenated gasoline program to bring it into attainment of the carbon monoxide National Ambient Air Quality Standards. Clean Air Act Section 175A(d) requires that maintenance plans assure prompt action to correct any violation of the standard that occurs after an area is redesignated to attainment, and mandatory Clean Air Act requirements must be included as contingency measures. The oxygenated gasoline program is a contingency measure in case the carbon monoxide National Ambient Air Quality Standards (NAAQS) is violated in Provo or Ogden. Therefore, this rule should be continued.
