(1) an inspection and downstream hazard evaluation by the executive director;

(2) a report of an inspection and downstream hazard evaluation by the owner's professional engineer;

(3) a breach analysis performed by either the executive director or the owner's professional engineer as described in §299.15(a)(4)(A)(i) of this title (relating to Hydrologic and Hydraulic Criteria for Dams); or
