CFR Citation: 40 CFR Part 52

EPA ID: [EPA-R07-OAR-2008-0100; FRL-8549-5]

NOTICE: PROPOSED RULES

ACTION: Approval and Promulgation of Implementation Plans:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Approval and Promulgation of Implementation Plans; State of Missouri

DATES: Comments on this proposed action must be received in writing by May 2, 2008.

DOCUMENT SUMMARY: EPA is proposing a revision to the Missouri State Implementation Plan (SIP) to include the State's recently revised ozone season NOX cap and trade rules for electric generating units (EGUs) and nonelectric generating units (NonEGUs) submitted on May 18, 2007. Two existing rules were revised by the State to allow for the transition into the State's recently adopted ozone season trading rule to meet the requirements of the Clean Air Interstate Rule (CAIR). The ozone season rules, an interstate cap and trade rule for EGUs and Non EGUs in the eastern onethird of the State and a statewide intrastate trading rule for EGUs, were revised to include language that will rescind their requirements in the year 2009, the year CAIR compliance begins. The CAIR ozone season trading rule is more restrictive than the aforementioned rules, and this action is needed to avoid imposing duplicative requirements for the affected sources in the year 2009 and thereafter.

SUMMARY: Missouri,

SUPPLEMENTAL INFORMATION

In the final rules 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 revision amendment and anticipates no relevant adverse comments to this action. 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 in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. 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 EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts 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.
