The local emergency services agency for the county where the Dam is located, via 9-1-1 call, if the dam has a Significant Hazard Rating;

(b)

The Department; and

(4)

If the Department is aware of conditions which indicate that immediate action is needed to prevent a Dam Failure, the Department may contact and advise the owner, operator, or individual in charge of the Dam regarding necessary actions to prevent the Dam Failure.

(5)

If a Dam has a Significant or High Hazard Rating and presents an imminent risk of dam failure, the Department or its agents or representatives may enter the property without notice or permission of the pertinent landowner to access the Dam and evaluate the condition or risk or to undertake necessary actions described in subsections (6) and (7).The Department’s entry onto property pursuant to this subsection shall be to the extent entry is reasonable or necessary.
