S-3.1.01, r. 1 - Dam Safety Regulation

Section 57 Disposition versions

2014-11-13

57. The following information and documents, in addition to those required by the Act, must be submitted with an application for authorization for the construction of a dam or for a structural alteration that affects all parts of the structure or that, because of the scope of the work, is equivalent to reconstructing the dam:

(1)  the appropriate hydrological and hydraulic studies;

(2)  the recommendation of the engineer responsible for the dam project plans and specifications in respect of the failure consequence category of the dam, to which is appended the dam failure analysis, rough maps or characterization required under section 18 for the consequence category the engineer considers appropriate for the dam;

(3)  the impounded water management plan summary if such a plan is required under Subdivision 1 of Division III for the dam to be constructed;

(4)  a description of emergency preparedness procedures in the event of a dam failure or failure of the temporary structures during the construction referred to in the application, if an emergency action plan is required under Subdivision 2 of Division III for the dam to be constructed;

(5)  the structural and foundation stability studies for the dam to be constructed, including geotechnical investigations;

(6)  seismic stability calculations for the dam to be constructed, unless the dam failure consequence category is “very low” or “low”;

(6.1)  the opinion of the engineer in charge on the liquefaction potential of the dam and its foundation and the data on which that opinion is based, unless the dam failure consequence category is “very low” or “low”;

(7)  the results of a topographic analysis of the reservoir rim;

(7.1)  if applicable, the recommendations of the engineer in charge as to the need for an intervention at the locations, on the reservoir rim, through which overflow could occur during a flood equal to the dam’s safety check flood; and

(8)  detailed cost estimates of the planned work.

A $200 deposit on the fees prescribed in section 64 must accompany the application for authorization. The deposit is not refundable under any circumstances.

O.C. 300-2002, s. 57; O.C. 17-2005, s. 10; O.C. 402-2011, s. 8; O.C. 901-2014, ss. 18 and 22.

(5)  the structural and foundation stability studies for the dam to be constructed, including geotechnical investigations;

(6)  seismic stability calculations for the dam to be constructed, unless the dam failure consequence category under sections 17 and 18 is Very Low or Low, but in the latter event, only if the dam is situated in seismic zone 1, 2 or 3;

(7)  a topographic analysis of the reservoir rim with respect to the safety check flood, if applicable; and

(8)  detailed cost estimates of the planned work.

A $200 deposit on the fees prescribed in section 64 must accompany the application for authorization. The deposit is not refundable under any circumstances.
