Supervisory authorities have the right to withdraw operation permit in case the safety declaration was not submitted on time. First of all the safety level of hydraulic structure depends on its operational status. According to the Federal Law [1], the owner of hydraulic structures must develop their safety criteria. Diagnostic parameters (settlements, flow rates, hydraulic gradients, etc.) of structures are compared with corresponding safety criteria to identify their operational status. In Russia two levels of safety criteria are used: K1—precautionary level, K2—minimum allowable level. Under current legislation, the owner of hydraulic structure or its operator (in case the structure is state or municipally owned) must provide financial guarantee of civil liability. Civil liability in case of damages caused by failure of hydraulic structure, except force majeure, is guaranteed by funds of the owner or operator and by insurance. According to the Federal Law, the civil liability risk is subject to compulsory insurance for the whole period of hydraulic structure’s construction and operation. The terms and conditions of insurance are regulated by the Federal Law “On Compulsory Insurance of Civil Liability of the Owner of a Hazardous Object for Inflicting Damage as a Result of an Accident at the Hazardous Object” [2]. The financial guarantee is set according to the results of estimation of possible loss suffered by third parties (natural or legal persons or their property) in case the hydraulic structure fails [5]. The estimation, which is fulfilled according to special methodology, is submitted to the supervisory authority called Rostechnadzor together with the safety declaration. The financial guarantee should be indexed (increased) every year depending on the inflation rate. The process is fulfilled by the owner in accordance with the change of the consumer price index [7]. The safety declaration justify the whole complex of measures aimed to maintain and enhance (if needed) the safety level set by building codes and standards. The Federal Law [1] stipulates the following responsibilities of the owner:  To control the parameters of hydraulic structures themselves, natural and technogenic influence, assess the safety of hydraulic structures and if needed, to analyze causes of its decrease;  To develop safety criteria and specify them timely;  To inspect the structures regularly;  To operate the structures according to active codes and standards;  To develop and implement measures aimed to maintain technically sound state of structures and their safety;  To develop safety declarations and submit them to supervisory authorities. Thus, current legislature of Russia covers all the stages of life-cycle of hydraulic structures, including design, construction, operation, closure and demolition. This legislative system includes the assessment of operational safety, ability of the owner to eliminate emergencies and failure risk estimation. The system also includes organization of supervision which is fulfilled by state authorities. 900
