          - 40 CFR Part 52
          - [EPA-R05-OAR-2017-0280; FRL-9969-88-Region 5]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Wisconsin State Implementation Plan (SIP) submitted by the Wisconsin Department of Natural Resources (WDNR) to EPA on May 16, 2017. The revision replaces the definition of “emergency electric generator” with a broader definition of “restricted internal combustion engine”. In addition, the revision makes amendments to procedures for revoking construction permits as well as language changes and other administrative updates. Lastly, WDNR is withdrawing two Wisconsin Administrative Code provisions that affect eligibility under general and construction permits. WDNR requested these changes to align state and Federal requirements and ensure consistency. EPA is proposing approval of Wisconsin's May 16, 2017, request because the Agency has made the preliminary determination that this SIP revision is consistent with the Clean Air Act and applicable EPA regulations regarding PSD.

# 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, this rule will be effective on January 8, 2018. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 which is located in the Rules section of this                     **Federal Register**                    .
