ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 62

[IN147-1b; FRL-7464-5]


Approval and Promulgation of State Implementation Plans; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to approve the removal of State rules 
controlling fluoride emission limitations from existing primary 
aluminum plants as a revision to the plan for control of fluoride 
emissions from existing primary aluminum plants (plan) as requested by 
the State of Indiana on October 17, 2002, and January 22, 2003. Indiana 
has replaced this rule with another regulation which incorporates by 
reference current Federal requirements into the Indiana

[[Page 11484]]

Administrative Code. The rule being removed applies to a single source, 
Aluminum Company of America (ALCOA), located in Warrick County. Because 
ALCOA remains subject to more stringent Federal requirements, EPA 
approval should not result in an adverse impact on air quality.
    In the ``Rules and Regulations'' section of this Federal Register, 
EPA is approving the State's request as a direct final rule without 
prior proposal because EPA views this action as noncontroversial and 
anticipates no adverse comments. The rationale for approval is set 
forth in the direct final rule. If EPA receives no written adverse 
comments, EPA will take no further action on this proposed rule. If EPA 
receives written adverse comment, we will publish a timely withdrawal 
of the direct final rule in the Federal Register and inform the public 
that the rule will not take effect. In that event, EPA will address all 
relevant public comments in a subsequent final rule based on this 
proposed rule. In either event, EPA will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time.

DATES: Comments on this action must be received by April 10, 2003.

ADDRESSES: Written comments should be mailed to: J. Elmer Bortzer, 
Chief, Regulation Development Section, Air Programs Branch (AR-18J), 
USEPA, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.
    A copy of the plan revision request is available for inspection at 
the Environmental Protection Agency, Region 5, Air and Radiation 
Division, 77 West Jackson Boulevard, Chicago, Illinois 60604. (Please 
telephone Randolph Cano at (312) 886-6036 before visiting the Region 5 
Office.)

FOR FURTHER INFORMATION CONTACT: Randolph Cano, Environmental 
Protection Specialist, Regulation Development Section, Air Programs 
Branch (AR-18J), USEPA, Region 5, 77 West Jackson Boulevard, Chicago, 
Illinois 60604, (312) 886-6036.

I. What Action Is EPA Taking Today?

    The EPA is proposing to approve the removal of State rules 
controlling fluoride emission limitations from existing primary 
aluminum plants as a revision to the plan for control of fluoride 
emissions from existing primary aluminum plants as requested by the 
State of Indiana on October 17, 2002, and as supplemented on January 
22, 2003. The State submittal is in response to the repeal of these 
regulations from the Indiana Administrative Code (IAC). These rules 
have been superseded by other State rules which incorporate current 
Federal requirements into the IAC by reference. Because Federal 
requirements are federally enforceable, they need not be included in 
the State plan. The rule removed from the Indiana Plan applies to a 
single source, Aluminum Company of America (ALCOA) located in Warrick 
County. Because ALCOA remains subject to more stringent Federal 
requirements, Federal approval of this repeal should not result in an 
adverse impact on air quality.

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

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

    Authority: 42 U.S.C. 4201 et seq.

    Dated: February 27, 2003.

Acting Regional Administrator, Region 5.
