Do not submit information that you consider to be CBI or otherwise protected through 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.

SUPPLEMENTARY INFORMATION:

General Information

Extension of Public Comment Period

The notice of proposed rulemaking was signed by the Administrator on May 1, 2008 and published in the Federal Register on May 20, 2008 (73 FR 29184). The schedule for completion of this review is governed by a judicial order in Missouri Coalition for the Environment v. EPA (No. 4:04CV00660 ERW, Sept.14, 2005). In light of the numerous complex issues discussed in the notice of proposed rulemaking, EPA and the Missouri Coalition for the Environment jointly sought an amendment of the judicial order to extend the comment period on the notice of proposed rulemaking to August 4, 2008 and to extend the deadline for signature of the notice of final rulemaking to October 15, 2008. On July 1, 2008, the court granted the joint motion, and therefore EPA is extending the comment period until August 4, 2008.

What Should I Consider as I Prepare My Comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through www.regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI 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.

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—the agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.
• Explain why you agree or disagree, suggest alternatives, and substitute language for your requested changes.
• Describe any assumptions and provide any technical information and/or data that you used.
• If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.
• Provide specific examples to illustrate your concerns, and suggest alternatives.
• Explain your views as clearly as possible, avoiding the use of profanity or personal threats.
• Make sure to submit your comments by the comment period deadline identified.
