Subsection 214-3-3.43 - FINAL DESIGN REPORTConstruction or reconstruction may not commence until a final design report is received by the Agency. The final design report shall include:
a. A report of geotechnical investigations of the foundation soils or bedrock and of the materials to be used to construct or reconstruct the impounding structure.b. Design assumptions and analyses sufficient to indicate that the impounding structure will be stable during its construction or reconstruction and during the life of the impounding structure under all conditions of reservoir operations, including rapid filling and rapid drawdown of the impoundment.c. Confirmation of the stability of the reservoir rim area in order to safeguard against reservoir ruin slides of such magnitude as to create waves capable of overtopping the impounding structure and confirmation of stability during seismic activity.d. Design assumptions and analyses to indicate that seepage in, around, through, or under the impounding structure, foundation, and abutments win be reasonably and practically controlled so that internal or external forces or results thereof will not endanger the stability of the impounding structure.e. Calculations and assumptions relative to design of the spillway(s).f. Provision to insure that the impounding structure and appurtenances will be protected against significant deterioration or erosion due to freezing and thawing, wind and rain, or any combination thereof.g. Other pertinent design date, assumptions, and analyses commensurate with the nature of the particular impounding structure and individual site conditions. When required by the Agency, a delineation of the inundation zone will be prepared by the owner for "high" and "significant hazard" impounding structures.h. Plans and specifications as outlined in Section 3.54 of this chapter.i. After verifying that the dam construction methods and design specifications were met, authorization to impound water will be issued prior to filling the reservoir.j. The Agency shall accept, review, and notify the owner within [45] working days whether the Preliminary Design Report is acceptable or not. The same procedure shall be followed for the Final Design Report. C.M.R. 15, 214, ch. 3, § 214-3-3.4, subsec. 214-3-3.43
