Ambient Water Quality Criteria for Ammonia--Freshwater''. Written 
scientific views on the draft recommended criteria were to be submitted 
to EPA on or before March 1, 2010 (a 60-day request for scientific 
views). Since publication, the Agency has received several requests for 
additional time to submit comments. Therefore, EPA is extending the 
period of time in which the Agency will accept scientific views on the 
draft criteria document for an additional 30 days.

DATES: Scientific views must be received on or before April 1, 2010. 
Comments postmarked after this date may not be considered.

submitting comments.

    Instructions: Direct your comments to Docket ID No. EPA-HQ-OW-2009-

the public docket without change and may be made available online at

restricted by statute. Do not submit information that you consider to 
be CBI or otherwise protected through www.regulations.gov or e-mail. 
The www.regulations.gov Web site is an ``anonymous access'' system,

of the comment that is placed in the public docket and made available

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. For additional 
information about EPA's public docket visit the EPA Docket Center 
homepage at http://www.epa.gov/epahome/dockets.htm.
