Summary

EPA proposes to approve revisions to the Missouri State Implementation Plan (SIP) submitted October 27, 2009. This revision adds a new rule to reduce the concentration of fine particles (PM ^2.5 ) in the St. Louis nonattainment area by limiting sulfur dioxide (SO ² ) emissions (a precursor pollutant to PM ^2.5 ), from industrial boilers. EPA is approving this revision because it strengthens the Missouri SIP. EPA's approval of this SIP revision is being done in accordance with the requirements of the Clean Air Act (CAA).

Dates

Comments on this proposed action must be received in writing by February 25, 2013.

Supplementary Information

In the final rules section of the 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 noncontroversial revision amendment and anticipates no relevant adverse comments to this action. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the rules section of this Federal Register . Dated: January 9, 2013. Karl Brooks, Regional Administrator, Region 7.
