ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OH 129-1b; FRL-6464-6]


Approval and Promulgation of Maintenance Plan Revisions; Ohio

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Proposed rule.

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

SUMMARY: USEPA is proposing to approve an August 19, 1999, request from 
Ohio for a State Implementation

[[Page 59706]]

Plan (SIP) revision of the Columbiana County, Ohio ozone maintenance 
plan. The maintenance plan revision allocates a portion of the safety 
margin to the transportation conformity mobile source emissions budget 
for the year 2005. USEPA is approving the allocation of 0.5 tons per 
day of oxides of nitrogen (NOX) to the area's 2005 mobile 
source emissions budget for transportation conformity purposes. This 
allocation will still maintain the total emissions for the area at or 
below the attainment level required by the transportation conformity 
regulations. In the Final Rules section of this Federal Register, USEPA 
is approving the State's SIP revision, as a direct final rule without 
prior proposal because the Agency views this as a noncontroversial 
revision and anticipates no adverse comments. A detailed rationale for 
the approval is set forth in the direct final rule. If we receive no 
adverse comments in response to that direct final rule we plan to take 
no further activity in relation to this proposed rule. If USEPA 
receives significant adverse comments, in writing, which have not been 
addressed, we will withdraw the direct final rule and address all 
public comments received in a subsequent final rule based on this 
proposed rule. The USEPA will not institute a second comment period on 
this document.

DATES: Written comments must be received on or before December 3, 1999.

ADDRESSES: Send written comments to: J. Elmer Bortzer, Chief, 
Regulation Development Section, Air Programs Branch, (AR-18J), U.S. 
Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, 
Chicago, Illinois, 60604.

    What Action is USEPA Taking Today?
    In this action, we are proposing to approve a revision to the ozone 
maintenance plan for Columbiana County, Ohio. The revision will change 
the mobile source oxides of nitrogen emission budget that is used for 
transportation conformity purposes. The revision will keep the total 
emissions for the area at or below the attainment level required by 
law. This action will allow State or local agencies to maintain air 
quality while providing for transportation growth.

Where Can I Find More Information About This Proposal and the 
Corresponding Direct Final Rule?

    For additional information see the direct final rule published in 
the rules section of this Federal Register.
