ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 52

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adverse comments, with respect to either the Milwaukee-Racine or the Sheboygan area, the direct final rule will be withdrawn with regard to that area and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

Dated: November 24, 2010.
