ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R10-OAR-2014-0388 FRL-9913-85-Region 10]

Approval and Promulgation of State Implementation Plans; Idaho: 
Portneuf Valley PM10 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 (PM10). 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.

Regional Administrator, Region 10.
