Approval and Promulgation of Implementation Plans; Arkansas; 
Clean Air Interstate Rule Nitrogen Oxides Ozone Season Trading Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a revision to the Arkansas State 
Implementation Plan (SIP) submitted on August 10, 2007, enacted at 
Regulation 19--Arkansas Plan of Implementation for Air Pollution 
Control; Chapter 14, Sections 19.1401-19.1404; and Chapter 15, Section 
19.1501. This revision addresses the requirements of EPA's Clean Air 
Interstate Rule (CAIR) Nitrogen Oxides (NOX) Ozone Season 
Trading Program, promulgated on May 12, 2005 and subsequently revised 
on April 28 and December 13, 2006. EPA is proposing to determine that 
the SIP revision fully implements the CAIR NOX ozone season 
requirements for Arkansas. Therefore, as a consequence of the SIP 
approval, EPA will also withdraw the CAIR Federal Implementation Plan 
(CAIR FIP) concerning NOX emissions for Arkansas. The CAIR 
FIPs for all States in the CAIR region were promulgated on April 28, 
2006 and subsequently revised on December 13, 2006.
    The intended effect of this action is to reduce NOX 
emissions from the State of Arkansas that are contributing to 
nonattainment of the 8-hour ozone National Ambient Air Quality Standard 
(NAAQS or standard) in downwind states. This action is being taken 
under section 110 of the Federal Clean Air Act (the Act or CAA).

SUPPLEMENTARY INFORMATION: In the final rules section of this Federal 
Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no relevant adverse 
comments. A detailed rationale for the approval is set forth in the 
direct final rule. If no relevant adverse comments are received in 
response to this action, no further activity is contemplated. If EPA 
receives relevant adverse comments, the direct final rule will be 
withdrawn and all public comments received will be addressed in a 
subsequent final rule based on this proposed rule. EPA will not 
institute a second comment period. Any parties interested in commenting 
on this action should do so at this time. Please note that if EPA 
receives adverse comment on an amendment, paragraph, or section of the 
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.
    For additional information, see the direct final rule which is 
located in the rules section of this Federal Register.

    Dated: September 18, 2007.
