**Approval and Promulgation of State Implementation Plans; Idaho: Portneuf**  **Valley PM** 10 **Maintenance Plan Amendment to the Motor Vehicle**  **Emissions Budgets**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Idaho (Idaho or the State) on April 21, 2014, to amend the Portneuf Valley maintenance plan for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM 10). The SIP revision updates the on-road motor vehicle emissions inventory and motor vehicle emissions budgets (MVEBs) using the EPA’s Motor Vehicle Emissions Simulator (MOVES2010b) and the most recent road dust emission factors. This rulemaking action approves the SIP revision and thereby makes the MVEBs available for transportation conformity purposes. The EPA is approving this SIP revision because it is consistent with the Clean Cir Act (CAA).

**DATES :**  Comments must be received on or before August 18, 2014.

**SUPPLEMENTARY INFORMATION :**  For further information, please see the direct final action, of the same title, which is located in the Rules section of this Federal Register. The EPA is approving the State’s SIP revision as a direct final rule without prior proposal because the EPA views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If the EPA receives no adverse comments, the EPA will not take further action on this proposed rule.

If the EPA receives adverse comments, the EPA will withdraw the direct final rule and it will not take effect. The EPA will address all public comments in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, the EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

Dated: July 2, 2014. Dennis J. McLerran, Regional Administrator, Region 10.
