          - 40 CFR Part 52
          - [EPA–R08–OAR–2009–0790; FRL–9114–4]

# 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.

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.
