[EPA-R05-OAR-2010-0850; FRL-9239-1]


Approval and Promulgation of Air Quality Implementation Plans; 
Wisconsin; The Milwaukee-Racine and Sheboygan Areas; Determination of 
Attainment of the 1997 8-hour Ozone Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to determine under the Clean Air Act (CAA) 
that the Milwaukee-Racine and Sheboygan, Wisconsin areas have attained 
the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). 
The Milwaukee-Racine area includes Milwaukee, Ozaukee, Racine, 
Washington, Waukesha, and Kenosha Counties. The Sheboygan area includes 
Sheboygan County. The proposed determinations are based on complete, 
quality-assured and certified ambient air monitoring data that show 
that the areas have monitored attainment of the 1997 8-hour ozone 
standard for the 2006-2008 and 2007-2009 monitoring periods. 
Preliminary data available for 2010 indicate that the areas continue to 
monitor attainment. If EPA finalizes this action, as a result of these 
determinations, the requirements for these areas to submit attainment 
demonstrations and associated reasonably available control measures 
(RACM), reasonable further progress plans (RFP), contingency measures, 
and other State Implementation Plan (SIP) revisions related to 
attainment of the standard would be suspended for as long as the areas 
continue to attain the 1997 8-hour ozone standard. These determinations 
would also suspend the requirement for EPA to promulgate attainment 
demonstration, RFP, and any other attainment-related Federal 
Implementation Plans (FIPs) for these areas.

DATES: Comments must be received on or before January 14, 2011.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the attainment determinations as a direct 
final rule without prior proposal because the Agency views this as a 
noncontroversial action 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 this rule, no further 
activity is contemplated. If EPA receives adverse comments, with 
respect to either the Milwaukee-Racine or the Sheboygan area, the 
direct final rule will be withdrawn with regard to that area and all 
public comments received will be addressed in a subsequent final rule 
based on this proposed rule. EPA will not institute a second comment 
period. Any parties interested in commenting on this action should do 
so at this time. Please note that if EPA receives adverse comment on an 
amendment, paragraph, or section of this rule and if that provision may 
be severed from the remainder of the rule, EPA may adopt as final those 
provisions of the rule that are not the subject of an adverse comment. 
For additional information, see the direct final rule which is located 
in the Rules section of this Federal Register.
