ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OH 125-1b; FRL-6375-5]


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.

SUPPLEMENTARY INFORMATION: This Supplementary Information section is

    What action Is USEPA taking today?

corresponding direct final rule?

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.
