Air Plan Approval; Wisconsin; 2017 Revisions to NR 400 and 406; Withdrawal of Direct Final Rule

Due to the receipt of an adverse comment, the Environmental Protection Agency (EPA) is withdrawing the November 7, 2017, direct final rule approving a revision to the Wisconsin State Implementation Plan (SIP). The revision replaces the definition of ``emergency electric generator'' with a broader definition of ``restricted internal combustion engine'', makes amendments to procedures for revoking construction permits as well as language changes and other administrative updates, and lastly, removing from the SIP two Wisconsin Administrative Code provisions that affect eligibility of coverage under general and construction permits.
