[EPA-R09-OAR-2007-AZ-0295; FRL-8443-6]

 
Approval and Promulgation of Implementation Plans; States of 
Arizona and Nevada; Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve state implementation plans 
submitted by the States of Arizona and Nevada that address interstate 
transport with respect to the 8-hour ozone and fine particulate matter 
national ambient air quality standards. In so doing, EPA has determined 
that the plans submitted by Arizona and Nevada and approved herein 
satisfy requirements under Clean Air Act section 110(a)(2)(D)(i) for 
each State to submit a plan containing adequate provisions to prohibit 
interstate transport with respect to the standards for 8-hour ozone and 
fine particulate matter. EPA is proposing this action pursuant to those 
provisions of the Clean Air Act that obligate the Agency to take action 
on submittals of state implementation plans. The effect of this 
proposal would be to approve the Arizona and Nevada state 
implementation plans addressing interstate transport with respect to 
the 8-hour ozone and fine particulate standards and to eliminate 
obligations on the Agency to promulgate Federal Implementation Plans 
for these States addressing this same requirement.

SUPPLEMENTARY INFORMATION: Throughout this document, wherever ``we,'' 
``us,'' or ``our'' is used, we mean the EPA.
    EPA is proposing to approve state implementation plans submitted by 
the States of Arizona and Nevada that address interstate transport with 
respect to the 8-hour ozone and fine particulate matter national 
ambient air quality standards. In so doing, EPA has determined that the 
plans submitted by Arizona and Nevada and approved herein satisfy 
requirements under Clean Air Act section 110(a)(2)(D)(i) for each State 
to submit a plan containing adequate provisions to prohibit interstate 
transport with respect to the standards for 8-hour ozone and fine 
particulate matter. The effect of this proposal would be to approve the 
Arizona and Nevada state implementation plans addressing interstate 
transport with respect to the 8-hour ozone and fine particulate 
standards and to eliminate obligations on the Agency to promulgate 
Federal Implementation Plans for these States addressing this same 
requirement.
    In the Rules and Regulations section of this Federal Register, we 
are taking direct final action to take these actions because we believe 
that they are not controversial. If we receive adverse comments, 
however, we will publish a timely withdrawal of the direct final rule 
and address the comments in subsequent action based on this proposed 
rule. We do not plan to open a second comment period, so anyone 
interested in commenting should do so at this time. If we do not 
receive comments, no further activity is planned. For further 
information on this proposal and the rationale underlying our proposed 
action, please see the direct final rule.

    Dated: June 11, 2007.
