(d) Depending on its hazard potential classification,
a

(e) If the hazard potential classification of a dam changes, its next inspection shall
be scheduled based on the date of its previous inspection and the cycle of inspections
required for the new hazard potential rating.
(f) If an existing dam is discovered that falls under the authority of the act, it shall be
added to the end of the appropriate alphabetical listing, and its first inspection shall
be scheduled based on the system described in subdivisions (a) to (c) of this rule. If

recent inspections and department-permitted and approved repairs and alterations.
(h) Owners of more than 1 dam may request that the department schedule their
inspection reports to be due the same year if the dams have the same hazard potential
classification.
