ACTION: Proposed rule; announcement of extension of comment period.

SUMMARY: The EPA is extending the comment period for the proposed rule 
titled, ``Quality Assurance Requirements for Continuous Opacity 
Monitoring Systems at Stationary Sources'' that was published in the 
Federal Register on February 14, 2012. The proposed rule accompanied 
the direct final rule that was also published on February 14, 2012. The 
30-day comment period in the proposed rule is scheduled to end on March 
15, 2012. The extended comment period will close on April 30, 2012. The 
EPA is extending the comment period because of a request we received in

April 30, 2012.

provided, unless the comment includes information claimed to be 
Confidential Business Information (CBI) or other information whose

consider to be CBI or otherwise protected through www.regulations.gov

information unless you provide it in the body of your comment. If you 
send an email comment directly to the EPA without going through 
www.regulations.gov, your email 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, the 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 the EPA cannot read your comment due to technical 
difficulties and cannot contact you for clarification, the 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. For additional instructions on submitting comments,
