(1) The department may make revisions to a permit under this part, to minimize the impacts to the natural resources, public health, and safety or to improve aquatic nuisance control, if the proposed revisions do not change the scope of the project and the permittee requests the revisions in writing. The department shall not charge a fee for a request for revisions to a permit. The department shall approve a request for revisions to a permit in whole or in part or deny the request within 3 business days after the request is received. The request shall include all of the following information:

    (a) The proposed changes to the permit.

    (b) An explanation of the necessity for the proposed changes.

    (c) Maps that clearly delineate any proposed changes to the area of impact.

    (d) Additional information that would help the department reach a decision on a permit amendment.

    (2) If the permittee has written authorization to act on behalf of a person described in section 3303(4)(a), (b), or (c), upon written request of that person, the department shall transfer the permit to a new permittee with written authorization to act on behalf of that person. The department shall notify the original permittee of the transfer of the permit.

    (3) Subject to subsection (4), a permittee may, without a revision to the permit or certificate of coverage, expand the area of impact beyond that authorized in the permit or certificate of coverage to include adjacent areas of the same waterbody that become infested after the application for the permit or certificate of coverage was submitted to the department. The permittee may increase the amount of chemicals used, as authorized in the permit or certificate of coverage, by an amount proportionate to the expansion in the area of impact. Before the initial treatment of the expanded area, the permittee shall notify the department. The permittee shall, within 15 business days after the initial treatment of the expanded area of impact, provide the department with all of the following:

    (a) A written explanation of the necessity for the expansion of the area of impact.

    (b) A map that clearly delineates the changes to the area of impact.

    (c) A written statement specifying the increase in the amount of chemicals used or to be used as a result of the expansion of the area of impact.

    (d) The treatment dates for the expanded area of impact.

    (e) If the permit application fee under section 3306 would have been higher if the expanded area of impact had been included in the permit application, a fee equal to the difference between the application fee paid and the application fee that would have been due.

    (4) If the area of impact authorized in a permit or certificate of coverage is greater than 100 acres, a permittee shall not expand the area of impact under subsection (3) by more than 50% unless both of the following apply:

    (a) The permittee has notified the department in advance of the proposal to expand the area of impact. The notification shall include the information described in subsection (3)(a) and (b).

    (b) The department has not, within 2 business days after receiving notification under subdivision (a), notified the permittee of specific concerns about the proposal and that the proposal requires a revision of the permit or certificate of coverage.
