ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[WI-113-7343B; FRL-7466-7]
Approval and Promulgation of State Implementation Plans;
Wisconsin
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The EPA is proposing to approve a revision to Wisconsin's
State Implementation Plan (SIP) for the attainment of the one-hour
ozone standard for the Milwaukee-Racine area. This SIP revision,
submitted to EPA on December 16, 2002, provides new compliance options
for sources subject to the state's rules limiting emissions of nitrogen
oxides (NOX) from large electricity generating units in
southeast Wisconsin. Under the revised SIP, sources would have the
option of complying with emissions limits on a per unit basis or
complying as part of an emissions averaging plan that also includes an
emissions cap. In addition, the revision creates a new categorical
emissions limit for new integrated gasification combined cycled units.
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 comments, 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: EPA must receive comments on this action by May 12, 2003.
ADDRESSES: You should mail written comments to: Carlton T. Nash, Chief,
Regulation Development Section, Air Programs Branch (AR-18J), USEPA,
Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.
A copy of the state's request is available for inspection at the
above address.

I. What Action Is EPA Taking Today?
EPA is proposing to approve, as part of the Wisconsin ozone SIP,
rules that would allow sources to use emissions averaging and an
emissions cap as a option for complying with ozone season limits on
emissions of NOX. These limits apply to large electricity
generating units in southeast Wisconsin; EPA approved the rules setting
these NOX emissions limits into Wisconsin's SIP on November
13, 2001 (66 FR 56931). The limits are expressed in mass of allowable
emissions per unit of heat input (pounds per million Btu).
Emissions averaging will allow units subject to the NOX
emissions limits of NR 428 of the Wisconsin Administrative Code to
create emissions averaging plans in which the compliance of multiple
units would be assessed collectively, based on their aggregate
emissions rate. The allowable emissions rate for each unit is reduced
by 0.01 pounds per million btu in determining the aggregate allowable
emissions rate. Beginning in 2008, sources that participate in an
emissions averaging plan must also collectively meet a NOX
emissions cap that is consistent with the one-hour ozone attainment
plan for southeast Wisconsin. The use of emissions averaging plans will
provide compliance flexibility for NOX emissions sources,
while ensuring that NOX emissions are no higher than they
would have been in the absence of averaging.
