ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2008-0342; FRL-8581-8]


Approval and Promulgation of Implementation Plans; State of 
Missouri

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve a State Implementation Plan (SIP) to 
revise the sulfur dioxide (SO2) emissions rates and 
averaging times for Kansas City Power & Light's Hawthorn Plant and 
Montrose Station in Missouri rule, Restriction of Emission of Sulfur 
Compounds. Previous changes to this rule were disapproved in 2006 
because EPA was concerned that the averaging times for the rates at 
these units had been dramatically increased from a 3-hour average to an 
annual average and that the revised averaging times were not 
demonstrated by the state to be protective of the short-term (3- and 
24-hour) sulfur dioxide (SO2) National Ambient Air Quality 
Standard (NAAQS). EPA believes that the recent changes, which EPA is 
now proposing to approve, have been shown by Missouri to be protective 
of the short-term SO2 NAAQS. This revision will ensure 
consistency between the state and the federally-approved rules.

DATES: Comments on this proposed action must be received in writing by 
July 21, 2008.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2008-0342, by mail to Amy Algoe-Eakin, Environmental Protection 
Agency, Air Planning and Development Branch, 901 North 5th Street, 
Kansas City, Kansas 66101. Comments may also

be submitted electronically or through hand delivery/courier by 
following the detailed instructions in the ADDRESSES section of the 
direct final rule located in the rules section of this Federal 
Register.

FOR FURTHER INFORMATION CONTACT: Amy Algoe-Eakin at (913) 551-7942, or 
by e-mail at [email protected].

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adverse comments, the direct final rule will be withdrawn and all 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