<br />erosion. The District therefore intends to replace the existing line with a 48-and 54-inch <br />diameter pipeline in a somewhat modified alignment. <br /> <br />1988 and 1991 Feasibilitv Studies <br /> <br />The initial feasibility study for the project was completed in October of 1987 by Western <br />Engineers of Grand Junction. The Western Engineers study included six alternatives and <br />proposed a pipeline route essentially parallel to the existing pipeline but bypassing the <br />existing 2,1 OO-foot long tunnel. The cost of the project was estimated at about $16.7 <br />million and the pipeline was designed with 36-and 42-inch diameter pipe. <br /> <br />After evaluation of the Western Engineers' report, it was determined that the <br />recommended alternative route presented special engineering and regulatory <br />considerations which would require additional analysis prior to final route selection. The <br />District therefore retained the firm of Steffen Robertson and Kirsten, Inc. (SRK) of <br />Lakewood to prepare a supplemental feasibility study. The SRK study was completed in <br />February 1991 and recommended a somewhat different pipeline route to include a 3,000- <br />foot tunnel adjacent to the existing tunnel. <br /> <br />CWCB Funding <br /> <br />The preliminary project configuration and $16.7 million cost estimate from the Western <br />Engineers study were presented to the Board in December of 1987. The Board <br />recommended to the legislature a loan of $8.0 million from the Construction Fund to the <br />District for the Plateau Creek Pipeline Project. The $8.0 million in funding was <br />subsequently authorized by the legislature in 1988 in SB-30. <br /> <br />In 1987, $62,500 was disbursed in the form of a loan to the District for the Western <br />Engineers feasibility study (and later made a part of the 1988 authorization). In March <br />1993, the Board approved an additional disbursement to the District of $400,000 for the <br />rehabilitation and enlargement of a pumping plant on the Colorado River to serve as an <br />alternate source of water supply for the District. The pumping plant project was <br />completed in 1995. <br /> <br />The loan contract (No. C-153670B) between the District and the CWCB for the <br />remainder of the authorization is for a principal amount of $7,537,500 at a lending rate of <br />5.0 percent with 30 annual payments beginning one year after substantial completion of <br />the project. Since June of 1995, a total of $1,110,349 has been disbursed for planning and <br />permitting work as described below. <br /> <br />Of the original $8.0 million authorization, the remaining balance then is $6,427,151 as <br />summarized in Table 2: <br /> <br />4 <br />
