Instructions: Direct your comments to Docket ID No. EPA-HQ-OAR-2010-0295. We also rely on documents in Docket ID Nos. EPA-HQ-OAR-2005-0029 and EPA-HQ-OAR-2003-0190 and incorporate those dockets into the record for this proposed rule. EPA's policy is that all comments received will be included in the public docket without change and may be made available on-line at http://www.regulations.gov,, including any personal information provided, unless the comment includes information claimed to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Do not submit information that you consider to be CBI or otherwise protected through http://www.regulations.gov or e-mail. The http://www.regulations.gov Web site is an “anonymous access” system, which means EPA will not know your identity or contact information unless you provide it in the body of 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:

This document extends the public comment period established in the notice of proposed rulemaking published in the Federal Register on June 8, 2010 (75 FR 32612). That notice proposed revisions to the standards of performance for stationary compression ignition and spark ignition internal combustion engines.

After publication of the proposed rule, EPA received requests from the American Petroleum Institute and the Alaska Department of Environmental Conservation for a 30-day extension of the comment period for the proposed rule. The requestors indicated that an extended comment period was necessary to allow time for a more thorough evaluation of the proposal and development of a complete set of comments.

The letters requesting an extension to the comment period can be found in the docket. EPA is hereby extending the comment period, which was set to end on August 9, 2010, to September 8, 2010.
