Approval and Promulgation of Maintenance Plan Revisions; Ohio

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Proposed rule.

SUMMARY: USEPA is proposing to approve a June 1, 1999, request from Ohio for a State Implementation Plan (SIP) revision of the Dayton/ Springfield, Ohio ozone maintenance plan. The maintenance plan revision reestimates the point source growth estimates and allocates 5.5 tons per day of VOC emissions to establish a new transportation conformity mobile source emissions budget for the year 2005. We are approving the allocation of the 5.5 tons per day volatile organic compounds (VOCs) growth estimate to the area's 2005 mobile source emissions budgets 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. We are also correcting a typographical error in the original maintenance plan approval for the point and area source VOC numbers for 2005. 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

[[Page 37492]]

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: We must receive comments by August 11, 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 Dayton/Springfield, Ohio. The revision will change the mobile source 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. We are also correcting a typographical error in the original maintenance plan approval. The original Federal Register approval on May 5, 1995, (60 FR 22289) contained a typographical error in Table 1 showing the VOC emissions from the source categories in the Dayton/Springfield area. The 2005 VOC emissions for point and area sources are incorrect in Table 1. The correct number for point source emissions in 2005 should be 98.0 and the correct number for area sources in 2005 should be 63.8 tons of VOC. These corrected numbers match the original submittal from the Ohio Environmental Protection Agency (OEPA) and are documented in the docket materials. This correction does not change the substance of the maintenance plan approval.

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.

Dated: June 29, 1999. David A. Ullrich, Acting Regional Administrator, Region 5.
