The board shall consult with the Departments of Agriculture, Health, and Natural Resources; the Pollution Control Agency; the Environmental Quality Board; and other appropriate state agencies during the review.

If a plan is disapproved, the board shall provide a written statement of its reasons for disapproval. A disapproved local water management plan must be revised by the county board and resubmitted for approval by the board within 120 days after receiving notice of disapproval of the local water management plan, unless the board extends the period for good cause.
