<br />.;, <br /> <br />. <br /> <br />. <br /> <br />structures. Where current, state-of-the-art engineering provides for <br />additional reliability to the system, the current criteria will be <br />used, (i.e., water hammer suppression equipment will be added to pump <br />discharge pipelines; current National Electric Code Standards will be <br />applied to electric motors, controls and services; repair/replacement <br />pump buildings will meet current building codes; and siphon structures <br />and pipelines will be cathodically protected in addition to a <br />dielectric coating being applied). <br /> <br />An investigation will be made to consider rerouting the canal across <br />Limekiln Gulch with a siphon structure, thus eliminating several miles <br />of existing canal and reducing maintenance of that reach of canal. <br /> <br />b. Geotechnical investigations - Where geotechnic engineering of existing <br />structures has proved adequate by long serve, and rehabilitation <br />provides for renewal/replacement of the structure, no additional <br />geotechnical investigations will be done. Where a reroute of the <br />canal is proposed, only feasibility-level geotechnical investigations <br />of the reach of canal rerouted will be done. Geotechnical <br />investigations required for design will not be done during feasibility <br />stages, but will be delayed until final design to assure that the <br />route selected is designated for use and access to property has been <br />secured. No required funds are included for geotechnical work during <br />the feasibility investigation. <br /> <br />c. Design <br /> <br />Items 1 and 2 - The design for replacement structures, including sizing, <br />hydraulic conditions (heads, flows and losses) will remain the same for <br />pumps, pump discharge pipelines, canals, siphon structures, and electrical <br />services (voltages). New designs will be provided only where a change in <br />water-carrying method is proposed (e.g., a siphon structure is to replace <br />an existing flume structure). Western will not duplicate the design for <br />rehabilitation of existing structures. <br /> <br />Item 3 Structural design criteria including allowable stresses in <br />materials of components will be provided, <br /> <br />Item 4 - Not applicable - No storage dam in system. <br /> <br />Item 5 - Not applicable. <br /> <br />Item 6 - Tbe irrigation system is out of the flood plain of the Gunnison <br />and Colorado Rivers and, therefore, these studies are not applicable. <br />Floods from the Colorado National Monument travel down water courses where <br />the Company has siphon structures and thus are not a hazard to the canals <br />or pump structures. From operation history, no problems have developed in <br />passing floods past the siphon and flume structures. No flood studies are <br />anticipated to be done. <br /> <br />Item 7 - Not Applicable <br /> <br />Item 8 - Inapplicable, as no new canals are anticipated to be built. <br /> <br />-4- <br />
