This schedule may be changed by the Director of the Division of Oil and Gas of the Department of Energy depending on specific site conditions.6.2 Inspection of Completed Dams - Until proper performance of the structure is evidenced/ the dam and appurtenances shall be inspected annually by an engineer(s) experienced in this respect. Should a storm of record occur (i.e. greater than or equal to a 100 year, 6 hour duration storm), a similar inspection shall be held. The inspection shall consider seepage, bulges, scarps, vertical displacement, excessive erosion, piping, maintenance deficiencies or other visual factors which could indicate potential failure of the embankment, spillways or appurtenances.
