3.3.3. Operation The documents should be sent to Dam Safety Unit in this phase are: 1) Result of instrumentation reading from construction until the latest reading 2) Dam behavior analysis based on instrumentation reading in number 1) and also inspection result in dam, reservoir and its vicinity, and appurtenance structure 3) Operation and maintenance manual which is has been adjusted based on the actual condition 4) Hydro mechanical operation report 5) Incidents and accidents report, such as earthquake, sliding, excess seepage, etc. 6) Executive summary report from impounding 7) Photos 3.3.4. Dam Closure The documents should be sent to Dam Safety Unit in this phase are: 1) Detail planning about termination, demolition of dam (if needed), including environment restoration, and safety of the environment. If the dam body and its appurtenance structure didn’t demolished, so maintenance and monitoring plan should be prepared include the operational organization. 2) Stability analysis for dam which is not demolished 3) Detail investigation about consequences or impact about dam removal for hydrology condition and hydraulically at the dam site 4) Environmental impact 5) Drawing 6) Photos 4. CONCLUSION Approval of the construction and management of dams in Indonesia is divided into four phases, namely the approval of design and construction, the initial charge, operation, and closure dam. This is intended to minimize the risk of dam failure and function in accordance with the purpose of development as well as to ensure the safety of the dam. 993
