ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2009-0790; FRL-9114-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Colorado; Revisions to Regulation Number 1

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed Rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve State Implementation Plan 
revisions submitted by the State of Colorado on August 3, 2007 to 
Colorado's Regulation Number 1 (revisions to the performance testing 
requirements for air curtain destructors). Colorado adopted these rule 
revisions on October 2, 2006. All other actions submitted by the State 
of Colorado concurrent with Colorado's Regulation Number 1 revision 
request will be acted on at a later date. In the ``Rules and 
Regulations'' section of this Federal Register, EPA is approving the 
State's SIP revision as a direct final rule without prior proposal 
because the Agency views this as a non-controversial SIP revision and 
anticipates no adverse comments. A detailed rationale for the approval 
is set forth in the preamble to the direct final rule. If EPA receives 
no adverse comments, EPA will not take further action on this proposed 
rule. If EPA receives adverse comments, EPA will withdraw the direct 
final rule and it will not take effect. EPA will address all public 
comments in a subsequent final rule based on this proposed rule. EPA 
will not institute a second comment period on this action. Any parties 
interested in commenting must do so at this time. Please note that if 
EPA receives adverse comment on an amendment, paragraph, or section of 
this rule and if that provision may be severed from the remainder of 
the rule, EPA may adopt as final those provisions of the rule that are 
not the subject of an adverse comment.

DATES: Comments must be received on or before June 9, 2010.

    Instructions: Direct your comments to Docket ID No. EPA-R08-OAR-
2009-0790. EPA's policy is that all comments received will be included 
in the public docket without change and may be made available online at 
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 www.regulations.gov or e-mail. 
The 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 
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. For additional information about EPA's public docket visit the 
EPA Docket Center homepage at http://www.epa.gov/epahome/dockets.htm.
