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.
