2014-09723. Approval and Promulgation of Implementation Plans; Wisconsin; Nitrogen Oxide Combustion Turbine Alternative Control Requirements for the Milwaukee-Racine Area

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

On February 24, 2014, the Wisconsin Department of Natural Resources (WDNR) submitted revisions to its nitrogen oxide (NO_X) combustion turbine rule for the Milwaukee-Racine area. This revision is contained in “2013 Wisconsin Act 91—Senate Bill 371” which allows alternative NO_X emission requirements for simple cycle combustion turbines that undergo a modification on or after February 1, 2001, if dry low NO_X combustion is not technically or economically feasible. This revision is approvable because it provides for alternative NO_X requirements subject to Environmental Protection Agency (EPA) approval on a case-by-case basis and therefore satisfies the reasonably available control technology (RACT) requirements of the Clean Air Act.

DATES:

Comments must be received on or before May 30, 2014.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial 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 rule, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. 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. For additional information, see the direct final rule that is located in the Rules section of this Federal Register.

Dated: March 20, 2014.

Regional Administrator, Region 5.
