<br />IT <br /> <br />Exhibit A <br />Grant for Proposed Feasibility Study of Long Hollow Reservoir and Red Mesa Reservoir Enlargement <br /> <br />. <br /> <br />. <br /> <br />r <br /> <br />k <br />t <br /> <br />Review Existing Data <br /> <br />A review will be conducted of available geologic, geotechnical and civil engineering <br />information to obtain an understanding of the site geology and subsurface conditions and <br />the construction quality control of the existing dam and reservoi.r at the site. Readily <br />available information from the U.S. Geological Survey (USGS), the owner, the USBR the <br />Colorado State Engineer's Office, and the SCS will be evaluated. The subsequent tasks <br />in the feasibility study will be based upon this available information. Ifnecessary, a <br />limited subsurface exploration and laboratory-testing program will be conducted to <br />supplement available information. <br /> <br />Topography <br /> <br />The topography of the site will be assessed by conducting aerial photography and <br />surveying the site to provide horizontal and vertical control. This work will allow an <br />orthophoto of the site to be produced, with a contour interval of2 feet. The orthophoto <br />will provide the basis for development of accurate area-capacity tables. <br /> <br />Hydrology <br /> <br />The specific hydrologic conditions that affect surface water flow in Hay Gulch will be <br />analyzed to determine if adequate water supplies will be available to maintain water <br />storage in the reservoir at levels that will allow the enlarged facility to function as <br />intended. Some long-term data exist that will aid in this analysis and additional area- <br />specific groundwater data are currently being collected under a separate project. <br /> <br />\.".-,', <br /> <br />c <br /> <br />r' <br /> <br />; . <br />t.., <br /> <br />, . <br />, <br />u <br /> <br />~;:. <br />-),: <br />~i'; <br /> <br />R. <br />. ;.~ <br />~d <br /> <br />L <br />~;. <br />t&. <br />~'i <br />:'.'" <br />:-;i. <br /> <br />Institutional Issues <br /> <br />F <br />6 <br />[ <br /> <br />A. National Environmental Policy Act ("NEP A") <br /> <br />The study will review whether there are any NEP A requirements for the <br />Proj ect. <br /> <br />B. Threatened and Endangered Species ("T&E") <br /> <br />A T &E species survey will be conducted at the site to determine if any <br />T &E species present problems that cannot be resolved. The T &E work will <br />include field surveys, literature research, and contacts with relevant state <br />and federal agencies. Potential mitigation needs will be considered, if <br />necessary. Because the enlargement project received a 404 permit from the <br />Army Corps of Engineers, the status of the endangered fish in the San Juan <br />River has already been considered and approved. The Red Mesa <br />Enlargement will be used for domestic and irrigation water in the same <br />proportions as in Red Mesa's original proposal to the Army Corps. If <br />endangered species issues should arise during the renewal of the Red Mesa <br />Enlargement Section 404 Permit, the section covering T &E species under <br />the Long Hollow Reservoir scope of work herein will be followed. <br /> <br />f. <br /> <br />!~' <br /> <br />r <br />~ <br />fl. <br />L <br /> <br />W~ <br /> <br />t~_ <br />
