    (iii) Activities expected to occur in the watershed in the future and how the activities will be monitored and controlled;
    (iv) The monitoring program the purveyor uses to assess the adequacy of watershed protection including an evaluation of sampling results; and
    (v) Special concerns about the watershed and how the concerns are being addressed;
    (b) System's compliance with the criteria to remain unfiltered under WAC 246-290-690, or, when applicable, the criteria required if the system provides a limited alternative to filtration under WAC 246-290-691; and
    (c) Significant changes in system design and/or operation that have occurred within the previous year that impact the ability of the system to comply with the criteria to remain unfiltered, or, if applicable, the ability of the system to provide a limited alternative to filtration in accordance with WAC 246-290-692.
    (7) The purveyor of a system attempting to remain unfiltered or to remain with a limited alternative to filtration shall submit a Filtration Decision Report at the request of the department. The report shall:
