          - 40 CFR Part 52 
          - [EPA-R08-OAR-2007-0648; FRL-8563-5] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve State Implementation Plans (SIPs) submitted by the States of South Dakota and Wyoming that address interstate transport with respect to the 1997 8-hour ozone and fine particulate matter (PM2.5) National Ambient Air Quality Standards. EPA has determined that the Interstate Transport declarations submitted by South Dakota on May 15, 2007, and by Wyoming on May 3, 2007, satisfy the requirements of the Clean Air Act section 110(a)(2)(D)(i) provisions, also known as the “good neighbor” provisions, that a state SIP contain adequate provisions prohibiting air pollutant emissions from sources or activities in the state from adversely affecting another state. This action is being taken under section 110 of the Clean Air Act.                     

                        In the “Rules and Regulations” section of this                         **Federal Register**                        , EPA is approving the States' SIP revisions as a direct final rule without prior proposal because the Agency views these as non-controversial SIP revisions 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.
