3 <br />• construction of a series of 80' x 150' well pads on 300' centers <br />(see page 2-3, Development Sequence and Schedule), attendant road <br />access (page 2-9, Access Roads), utilities (page 2-10, Natural <br />Gas Supply and page 2-11, Electrical Power) and an extensive <br />elevated pipeline network (see page 2-7, Solution Piping). A <br />representative 5-year well field layout is presented in Fig. 2-3. <br />It is estimated that surface clearing, excavation, or occupation <br />within any given mine panel will involve nearly 70~ of the land <br />surface (Table 2-2). <br />Permanent processing and administrative facilities on the <br />Piceance site will be housed on a 6.3 acre ridgetop site (Fig. 2- <br />2) A 13-acre lined evaporation pond may be located adjacent to <br />the facility site. The pond will collect stormwater drainage <br />from the processing plant along with waste products from boilers <br />and the cooling tower. American Soda is currently investigating <br />the feasibility of eliminating the Piceance site evaporation pond <br />altogether. <br />Product Pipeline <br />Mined product would be transported to the Parachute processing <br />facility as a slurry and the recycled water returned to the <br />Piceance mine site through a pair of parallel pipelines. The <br />proposed pipeline corridor is depicted in Figures 2-la through 2- <br />lh and described on pages 2-12 through 2-14. The selected route <br />would generally parallel existing pipeline corridors.(which hold <br />1 or more natural gas pipelines) for about 33 miles of its 44- <br />mile length (from Magnolia compressor stations, Fig. 2-lb, south <br />to the Parachute terminus). The pipeline is scheduled to be <br />constructed over a 4 to 5-month period beginning in April 2000. <br />Parachute Processin4 Facility <br />Final product processing and distribution would take place on°the <br />former Unocal Shale Oil Upgrade Facility site about 2.5 miles <br />northwest of Parachute, Colorado (Figures 2-lh and 2-9 and pp 2- <br />14 to 2-16) American Soda's reoccupation of this site would <br />require a 56-acre expansion to the existing 304-acre extent. <br />As proposed in the EIS, two lined evaporation ponds, a 15-acre <br />evaporation pond and an additional 21-acre purge pond, would be <br />required at the Parachute processing facility. <br />Water required for solution mining and product processing and <br />transport is expected to amount to about 1204 acre-feet per year, <br />and would be taken from the Colorado River at the existing Unocal <br />intake located near the town of Parachute. <br />• <br />
