[OH63-1-6403b, OH64-1-6404b; FRL-5020-6]


Approval and Promulgation of Implementation Plans; Ohio

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Proposed rule.


SUMMARY: The USEPA is approving, through direct final procedure, two 
exemption requests from the requirements contained in Section 18(f) of 
the Clean Air Act (Act) for the Toledo and Dayton ozone nonattainment 
areas in Ohio. These exemption requests, submitted by the State of 
Ohio, are based upon the most recent three years of ambient air 
monitoring data which demonstrate that the National Ambient Air Quality 
Standard (NAAQS) for ozone has been attained in each of these areas 
without additional reductions of nitrogen oxides (NOX). Section 
182(f) of the Act requires States with areas designated nonattainment 
of the NAAQS for ozone, and classified as moderate nonattainment and 
above, to adopt reasonably available control technology (RACT) rules 
for major stationary sources of NOX and to provide for 
nonattainment area new source review (NSR) for new sources and 
modifications that are major for NOX. Section 182(f) provides 
further that these requirements do not apply for areas outside an ozone 
transport region if USEPA determines that additional reductions of 
NOX would not contribute to attainment of the NAAQS for ozone in 
the area.
    In the Final Rules Section of this Federal Register, the USEPA is 
approving these exemption requests as a direct final rule without prior 
proposal because USEPA views this as noncontroversial 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 that direct final rule, no further activity is contemplated 
in relation to this proposed rule. If USEPA receives 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the direct final rule will be withdrawn and all public comments 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 rule. USEPA will not institute a second comment period on this 
action. Any parties interested in commenting on this action should do 
so at this time.

DATES: Comments on this action must be received by August 10, 1994.

ADDRESSES: Written comments should be mailed to: William L. MacDowell, 
Chief, Regulation Development Section, Air Enforcement Branch (AE-17J), 
USEPA, Region 5, 77 West Jackson Blvd., Chicago, Illinois 60604.
    Copies of the State's request and USEPA's analysis of it are 
available for inspection at: Regulation Development Section, Air 
Enforcement Branch (AE-17J), USEPA, Region 5, 77 West Jackson Blvd., 
Chicago, Illinois 60604.

FOR FURTHER INFORMATION CONTACT: Richard Schleyer, Environmental 
Engineer, Regulation Development Section, Air Enforcement Branch (AE-
17J), USEPA, Region 5, 77 West Jackson Blvd., Chicago, Illinois 60604.

SUPPLEMENTARY INFORMATION: For additional information see the direct 
final rule published in the Rules Section of this Federal Register.

    Authority: 42 U.S.C. 7401-7642.

    Dated: July 11, 1994.

Regional Administrator.
