ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2012-0763; FRL-9772-5]

Approval and Promulgation of Implementation Plans; State of 
Missouri; Control of Sulfur Emissions From Stationary Boilers

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

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 
(PM2.5) in the St. Louis nonattainment area by limiting 
sulfur dioxide (SO2) emissions (a precursor pollutant to 
PM2.5), 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).

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adverse comments, the direct final rule will be withdrawn and all 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.
