SUMMARY: The EPA is announcing an extension of the public comment 
period within the context of our proposed heavy-duty onboard 
diagnostics (OBD) requirements. (72 FR 3200, January 24, 2007) 
Specifically, we are extending the comment period for comments 
pertaining to the proposed service information availability 
requirements for engines used in highway vehicles over 14,000 pounds. 
These proposed requirements can be found in the proposed Sec.  86.010-
38(j). (72 FR 3322) The comment period will be extended from March 26, 
2007 to May 4, 2007. We are extending the comment period in response to 
a request to do so from the Engine Manufacturers Association.

DATES: Written comments pertaining to the proposed service information 
availability requirements of the proposed Sec.  86.010-38(j) must be 
received on or before May 4, 2007.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-HQ-

provided, unless the comment includes information claimed to be

consider to be CBI or otherwise protected through http://www.regulations.gov or e-mail. The http://www.regulations.gov Web site

your comment. If you send an e-mail comment directly to EPA without 
going through http://www.regulations.gov your e-mail address will be 

automatically captured and included as part of the comment that is 
placed in the public docket and made available on the Internet. 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:

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

    Submitting CBI. Do not submit this information to EPA through 
http://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.
