# SUPPLEMENTARY INFORMATION:

## I. Background

                    On December 9, 2011, the EPA responded by letter to all states and tribes regarding their designation recommendations for the 2008 ozone standards and posted the responses on the EPA's Internet Web site at                     *http://www.epa.gov/​ozonedesignations*. The EPA provided a public comment period on those responses which ended on February 3, 2012. On January 31, 2012, the EPA sent revised responses to Illinois, Indiana, and Wisconsin after considering quality-assured air quality monitoring data for 2011 submitted by Illinois on December 7, 2011. Because that air quality information was submitted shortly before the EPA issued its December 9, 2011, responses, the EPA did not have time to consider the information in those initial responses. The EPA has posted the revised responses to Illinois, Indiana, and Wisconsin on the EPA's ozone designations Web site and is reopening the public comment period for the limited purpose of inviting public comments on the revised responses to Illinois, Indiana, and Wisconsin during the comment period specified in the                     **DATES**                     section. The EPA intends to make final designation determinations for the 2008 ozone standards in spring 2012.                

## II. General Information

### A. What should I consider as I prepare my comments for the EPA?

                    1.                     *Submitting Confidential Business Information*. Do not submit this information to the EPA through                           ( print page 8212)    *www.regulations.gov*                     or email. Clearly mark the part or all of the information that you claim to be confidential business information. For confidential business information in a disk or CD-ROM that you mail to the EPA, mark the outside of the disk or CD ROM as confidential business information and then identify electronically within the disk or CD ROM the specific information that is claimed as confidential business information. In addition to one complete version of the comment that includes information claimed as confidential business information, a copy of the comment that does not contain the information claimed as confidential business information must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. Send or deliver information identified as confidential business information only to the following address: Roberto Morales, U.S. EPA, Office of Air Quality Planning and Standards, Mail Code C404-02, Research Triangle Park, NC 27711, telephone (919) 541-0880, email at                     *morales.roberto@epa.gov,*                     Attention Docket ID No. EPA-HQ-OAR-2008-0476.                

                    2.                     *Tips for Preparing Your Comments.*                     When submitting comments, remember to:                
    - Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register                      date and page number).                
    - Follow directions.
    - Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

### B. Where can I get a copy of this document and other related information?

                    The EPA has established a docket for the ozone designations rulemaking for the 2008 ozone standards at EPA-HQ-OAR-2008-0476. In addition, the EPA has established a Web site for the ozone designations rulemaking at                     *www.epa.gov/​ozonedesignations*. The Web site includes the state and tribal designation recommendations, information supporting the EPA's preliminary designation decisions, as well as the rulemaking actions and other related information that the public may find useful.
