The Department shall be notified if sloughing, slope failure, or excessive erosion of a facility occurs, or where other failure has occurred. The owner or permittee may be required to provide an engineering evaluation and any other information the Department determines necessary to ensure that the design and construction is acceptable such that the excessive erosion or other failure is not likely to recur. In the event the existing design or construction is determined to be inadequate, the owner or permittee may be required to submit an application for a major modification.
