The department shall then accept comments on the proposed revision for 30 days, commencing on the date that notice is given. If an affected state has submitted comments in response to the notice and the department has not accepted those comments, the department shall notify that state and EPA in writing of its decision not to accept the comments and the reasons for that decision.

NR 407.12(4)(b) (b) The department may not act on a request for a minor permit revision until 45 days after providing notice of the requested revision to EPA or until EPA has notified the department that EPA will not object to issuance of the minor permit revision, whichever is first. Within 90 days of the department’s receipt of a complete request for a minor permit revision or 15 days after the end of EPA’s 45-day review period, whichever is later, the department shall do one of the following:

NR 407.12(4)(b)1. 1. Issue the minor permit revision as proposed.

NR 407.12(4)(c) (c) The permittee may make the change proposed in its request for a minor permit revision immediately after it files the request.

During this time period, the permittee need not comply with the permit terms and conditions it is seeking to revise. However, if the permittee fails to comply with its suggested draft new permit terms and conditions during this time period, the existing permit terms and conditions it seeks to revise may be enforced against it. If the department determines that the proposed change may not be made pursuant to a minor permit revision, and the permittee has already made the change at the facility, the permittee shall be liable for any violations of the permit conditions it is requesting to be revised.

NR 407.12(5) (5) Permit shield. The permit shield under s. 285.62 (10) (b), Stats., may not be extended to minor permit revisions.
