INSTRUCTIONS: Direct your comments to Docket ID No. EPA-HQ-OAR-2009-0171.

Do not submit information that you consider to be CBI or otherwise protected through http://www.regulations.gov or e-mail.

If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD-ROM you submit. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment. Electronic files should avoid the use of special characters, any form of encryption, and be free of any defects or viruses.
