ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R07-OAR-2011-0451; FRL-9441-1]
Approval and Promulgation of Air Quality Plans: State of Missouri
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve an April 20, 2011, request from
the State of Missouri to exempt sources of Nitrogen Oxides
(NOX) in the Missouri portion of the St. Louis (MO-IL)
metropolitan 8-hour ozone nonattainment area from the Clean Air Act
(CAA) requirements for NOX Reasonably Available Control
Technology (RACT) for purposes of attaining the 1997 8-hour ozone
National Ambient Air Quality Standard (NAAQS). The Missouri
NOX RACT waiver request for its portion of the St. Louis
metropolitan 8-hour ozone nonattainment area is based on the most
recent three years of complete, quality-assured ozone monitoring data,
which demonstrate that additional reductions of NOX
emissions in the Area would not contribute to attainment of the 1997 8-
hour ozone NAAQS.
DATES: Comments on this proposed action must be received in writing by
August 22, 2011.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2011-0451, by mail to Ms. Lachala Kemp, Air Planning and
Development Branch, U.S. EPA Region 7, 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: Lachala Kemp, Air Planning and
Development Branch, 901 N. 5th Street, Kansas City, Kansas 66101 at 913
551 7214, or by e-mail at [email protected].
SUPPLEMENTARY INFORMATION: In the final rules section of this Federal
Register, EPA is approving the State's request to exempt sources of
NOX in the Missouri portion of the St. Louis (MO-IL)
metropolitan 8-hour ozone nonattainment area from the CAA requirements
for NOX RACT for purposes of attaining the 1997 8-hour ozone
NAAQS. EPA is approving the Missouri's SIP revision as a direct final
rule without prior proposal because the Agency views this as a non-
controversial submittal and anticipates no adverse comments. A detailed
rationale for the approval is set forth in the direct final rule. If no
adverse comments are received in response to this action no further
activity is contemplated. If EPA receives 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 rule. EPA
will not institute a second comment period. Any parties interested in
commenting on this action should do so at this time.
For additional information, see the direct final rule, which is
located in the rules section of this Federal Register.
Dated: July 12, 2011.
Karl Brooks,
Regional Administrator, Region 7.
