          - 40 CFR Parts 52 
          - [EPA-R05-OAR-2007-1085; FRL-8519-2] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule.

# SUMMARY:

                        EPA is proposing approval of a revision to the Ohio State Implementation Plan (SIP) submitted by letter on June 16, 2005. This revision addresses the requirements of EPA's NOX                         SIP Call which requires further reductions in NOX                         emissions based on cost-effective control measures for large internal combustion engines. The revision also addresses some revisions to the State's NOX                         SIP Call trading program. EPA is proposing to determine that the Ohio SIP revision satisfies the requirements for Phase II of the NOX                         SIP Call and the NOX                         SIP Call trading program because, when implemented, these will meet Ohio's emission reduction requirements under Phase II of the NOX                         SIP Call.

# 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 non-controversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, EPA will withdraw the direct final rule and will address all public comments received 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 meaningful adverse comment on an amendment, paragraph, or section 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. For additional information, see the direct final rule which is located in the Rules section of this                     **Federal Register**                    .
