or projecting into the Dow West property, for private lands <br />adjacent to the Naval Oil Shale Reserve. <br />- Diversion of up to 7,200 acre-feet per year of water from <br />the Colorado River at Grand Valley which will be piped to <br />the plant site. This diversion is contingent upon Colony <br />finali2ing a proposed contract with the WRR for water from <br />Green Mountain or Ruedi Reservoir. Due to current agency <br />administrative uncertainties, this contract may be adminis- <br />tered by the Colorado River Water Conservation District. This <br />contract would provide a source of water during low periods <br />in the Colorado River when Colony's private water rights are <br />insufficient to meet plant requirements. <br />- Construction and operation of the preceding facilities would <br />require a number of actions by federal, state and local agencies. <br />The major permits which will be required, and their status <br />are listed in Table D-1. <br />RETORTING AND UPGRADING <br />The retorting and upgrading operations convert the crushed raw <br />shale into useable products and disposable wastes. The products <br />include low sulfur oil (less than 0.001 percent sulfur by weight), <br />LPG, sulfur, ammonia, and coke. Fuels produced by the plant <br />for internal consumption include treated fuel gas, a Cq liquid <br />steam containing butanes and butenes, fuel oil and diesel oil. <br />The primary waste is processed shale. <br />A block diagram showing the flow of material through the retorting <br />and upgrading section is shown in Figure D-2. These separate <br />processing units, which involve many recycle and side stream <br />operations, process the crushed raw shale into oil, by-products, <br />D-d <br />
