2. (2) The comprehensive dam safety evaluation shall consists of, but not be limited to,---
   • (a) review and analysis of available data on the design, construction, operation, maintenance and performance of the structure;
   • (b) general assessment of hydrologic and hydraulic conditions with mandatory review of design floods as specified by the regulations;
   • (c) general assessment of seismic safety of specified dam with mandatory site specific seismic parameters study in certain cases as specified by the regulations;
   • (d) evaluation of the operation, maintenance and inspection procedures; and
   • (e) evaluation of any other conditions which constitute a hazard to the integrity of the structure.

The comprehensive dam safety evaluation referred to in section 38 shall be compulsory in the case of, —

1. (a) major modification to the original structure or design criteria;
2. (b) discovery of an unusual condition at the dam or reservoir rim; and
3. (c) an extreme hydrological or seismic event

1. (1) The owner of a specified dam shall report the results of the dam safety evaluation undertaken under section 38 or section 39 to the State Dam Safety Organisation.
2. (2) The reports referred to in sub-section (1) shall include, but not be limited to, —
   • (a) assessment of the condition of the structure based on the visual observations and available data on the design, hydrology, construction, operation, maintenance and performance of the structure;
   • (b) recommendations for any emergency measures or actions, if required, to assure the immediate safety of the structure;
   • (c) recommendations for remedial measures and actions related to design, construction, operation, maintenance and inspection of the structure, if required;
   • (d) recommendations for additional detailed studies, investigations and analysis, if required; and
   • (e) recommendations for improvements in routine maintenance and inspection of dam, if required.
3. (3) Where the safety evaluations undertaken under section 38 or section 39, results in recommendations for a remedial action, the State Dam Safety Organisation shall pursue with the owner of the specified dam to ensure that remedial measures are carried out in time, for which the owner shall provide adequate funds.
4. (4) Where there is any unresolved matter emerging between an independent panel of experts referred to in sub section (1) of section 38 and the owner of the specified dam, the matter shall be referred to the State Dam Safety Organisation, and, in case no agreement is arrived at, the matter shall be referred to the Authority which shall render its advice and send recommendations to the State Government concerned for implementation.
