(b) As part of the continuing monitoring process for an approved sustained yield plan, as described in subdivision (a), the department shall hold a public hearing on the plan if requested by an interested party who submits, in writing, a request based on substantial evidence of potential noncompliance with any of the following:

The department shall hold the public hearing within 120 days after the date of the close of the six-month request period.
