CHAPTERFIVE Draft EIS ReYislons • km) from the Pazachute Site and the West Elk Wilderness Area is over ]00 miles away (161 Page 3-48; Cultural and Paleontological Resources Segments of new pipeline corridor that have not been previously surveyed would require intensive pedestrian survey for the proposed action. One segment extends southeastward from the southeast corner of the lease area where the proposed pipeline corridor exits the Piceance Site to the Greasewood Compressor Station. The first approximately four miles of this corridor follows the floodplain of Hatch Gulch. Previous research in the Piceance Basin has documented the fact that sites aze typically not found along drainages because of the thick vegetative scresge cover and depositional setting. Since this area along Hatch Gulch is unlikely to result in the discovery of cultural resources by means of survey, the BLM is not requiring a cultural resources inventory of this portion (Belle 1998). The proposed route for the pipeline route as it drops off of Davis Point into the Parachute Creek Valley has not been surveyed for cultural resources. Portions of this route along Parachute Creek would be surveyed prior to construction. The portion of this route as it descends the steep face of Davis Point would not require a cultural resources survey. However, the cliffs would be viewed from a safes location for evidence of mining adits, tunnels, flumes, rock art, shelters, etc. prior to construction. Page 3-46; Cultural and Paleontological Resources • These surveys have resulted in the discovery and recordation of 4847 prehistoric sites, five historic sites, 45 prehistoric isolated fords, and two isolated fossil bone localities. The types of sites recorded during the survey of the Piceance Site included prehistoric open camps, open lithic, sheltered camps and open azchitectural sites, and historical drift fences and a dugout. The isolated finds are ineligible for the National Register of Historic Places (NRHP) according to the criteria at 36 CFR 60.4, and so aze the five historic sites. Of the 4847 prehistoric sites, seven have been recommended as eligible for the NRHP, 27 have been recommended as ineligible, and additional data are required in order to determine the NRHP status of the remaining x.413. Generally, sites were recommended as eligible because they demonstrated the potential to yield significant information on the prehistory of the region. Page 3-50; land Use and Recreation The BLM manages the Ryan Gulch and Dudley Bluffs ACECs (Figure 3..1-1-~ 3.12-1). These ACECs were established by the BLM for the protection of two federally threatened plant species, the Dudley Bluffs twinpod (Physaria obcordara) and the Dudley Bluffs bladderpod (Lesquere/!a congests). Most of the Ryan Gulch ACEC is located south of the Piceance Site, however, the it overlaps the Piceance Site in the northern half of Section 29 Tl S R97W (approximately 240 acres). The Dudley Bluffs ACEC is located south of the Piceance Site and does not overlap project boundaries.

The site is currently owned by Unocal, which developed the site as an industrial facility for oil shale development. The anticipated oil shale development did not 5-17
