ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2015-0227; FRL-9927-69-Region 8]

Approval and Promulgation of Air Quality Implementation Plans; 
State of Utah; Utah County--Trading of Motor Vehicle Emission Budgets 
for PM10 Transportation Conformity

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a State Implementation Plan (SIP) revision submitted by the 
State of Utah. On March 9, 2015, the Governor of Utah submitted a 
revision to the Utah SIP, adding a new rule regarding trading of motor 
vehicle emission budgets for Utah County. The rule allows trading from 
the motor vehicle emissions budget for primary particulate matter of 10 
microns or less in diameter (PM10) to the motor vehicle 
emissions budget for nitrogen oxides (NOX) which is a 
PM10 precursor. The resulting motor vehicle emissions 
budgets for NOX and PM10 may then be used to 
demonstrate transportation conformity with the SIP. The EPA is 
proposing approval of this SIP revision in accordance with the 
requirements of section 110 of the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION: In the ``Rules and Regulations'' section of 
this Federal Register, EPA is approving the State's SIP revision as a 
direct final rule without prior proposal because the Agency 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 EPA receives no adverse comments, EPA will not take further 
action on this proposed rule. If EPA receives adverse comments, EPA 
will withdraw the direct final rule and it will not take effect. EPA 
will address all public comments in a subsequent final rule based on 
this proposed rule.
    EPA will not institute a second comment period on this action. Any 
parties interested in commenting must do so at this time. For further 
information, please see the ADDRESSES section of this notice.
    Please note that if EPA receives adverse comment on a distinct 
provision of this rule and if that provision may be severed from the 
remainder of the rule, EPA may adopt as final those provisions of the 
rule that are not the subject of an adverse comment. See the 
information provided in the Direct Final action of the same title which 
is located in the Rules and Regulations Section of this Federal 
Register.

    Authority:  42 U.S.C. 7401 et seq.

    Dated: May 1, 2015.

Regional Administrator, Region 8.
