<br />CNAPTERTWO Proposed Action and Alternatives , <br /> <br />The berms fot each pond would be designed in accordance with Bureau of Reclt¢nation Small <br /> <br />Dam Design criteria. Adequate freeboazd would be provided to: 1) accommod~.te the normal , <br />maximum operating level plus the 100-year (24-hour) precipitation event; 2) accommodate wave <br />action on the pond level of (1) without overtopping; and 3) provide at least 1 foot of freeboard <br /> <br />above the level determined in (2). Pond volume would be obtained by a combination of ' <br />excavation and berming. Outside slopes would be 3:1 and inside slopes would lie 2:1. <br />Anticipated berm height is 10 feet. ' <br />2.2.3.3 Development Sequence and Schedule <br />ll <br />i <br />f <br />f <br />il ' <br />A <br />modificat <br />on o <br />existing <br />ac <br />ities and construction of new facilities at the Parachute Site are <br />anticipated to be completed within about 18 months of approval of the EIS Record of Decision <br />(ROD), with facility startup upon completion of construction. , <br />2.2.3.4 Final Product Processing <br /> <br />Product solution would be transported to the Pazachute Site via the pipeline. At the Parachute <br />Site, the solution would undergo final processing into soda ash and sodium bica~•bonate. Final <br />processing would primarily include crystallizing, collecting, and drying processf:s. During , <br />processing, water from the solution would be collected and recycled by pumping; it back to the <br />Piceance Site for reuse in the mining operation. Sodium bicarbonate product would be sorted <br />into grades and transferred by conveyor to either a railcar loadout or to a bagging; area for truck ' <br />transport. The soda ash product would be transferred by conveyor to storage silos and <br />subsequently to a railcar loadout. ' <br />2.2.3.5 Ancillary Facilities and Infrastructure <br /> , <br />Access Roads <br />The Parachute Site is 2.5 miles northwest of the town of Parachute, Colorado. P,ccess to the , <br />Pazachute Site would be via Garfield County Road 215 (Parachute Creek Road). Access to <br />project facilities within the Pazachute Site would be provided by existing paved :roads within the <br />facility (Figure 2-9). ' <br />Rail Spur ' <br />The original Unocal facility included an approximately 4-mile-long rail spur from the Parachute <br />Site southeast to the Union Pacific Railroad line that parallels Interstate 70. The tracks for the <br />rail spur would have to be reset prior to operation because the Unocal tracks were removed in ' <br />1997. The tracks would follow the same alignment as the Unocal rail spur. The rail spur is <br />shown on Figure 2-9. ' <br />Natural Gas <br />An existing natural gas pipeline would serve the Parachute Site. It enters the project from the ' <br />east as shown in Figure 2-9. <br />2-16 ' <br />
