The existing three-party corridor includes pipelines operated by Northwest Pipeline, Colorado Interstate Gas (CIG), and Barrett Resource's. This pipeline corridor trends south-southeast for approximately 2 miles frorn the Greasewood Compressor Station before it enters Collins Gulch (MP 10.5). To avoid impacts to other pipelines in Collins Gulch and to minimize impacts to the Collins Gulch streambed, a new route in Collins Gulch was selected in consultation with the BLM. At the upper end of Collins Gulch, the new route will. cross Rio Blanco County Road 3 and the streambed in the same location as the existing pipelines. The project pipelines will progress south between the streambed (on the west) and the existing CIG line (on the east) for approximately one-half mile, at which point the route will again cross the streambed and Rio Blanco County Road 3. It then follows the west side of the road for approximately 3 mile:> to cross both Rio Blanco County Road 5 and Piceance Creek again near MP 14. The pipeline corridor then crosses a small ridge into Stewart Gulch. • As it follows the valley bottom, the pipeline corridor crosses West Fork Stewart Gulch, Stewart Gulch (twice), and Middle Fork Stewart Gulch over a distance of 1.5 miles. It then crosses an unimproved private road and begins its ascent of Barnes Ridge at MP 17, progressing essentially due south. After traveling along the top of Barnes Ridge for 7 miles, the: pipeline corridor turns east (IvIP 23.5) for approximately one-half mile, crossing Dry Fork Stewart Gulch to the next ridge (MP 24). It then continues south aztd crosses into the Pazachute Creek drainage basin (MP 27.5) and on for approximately 8 miles to Davis Point (MP 32). At Davis Point, the Yankee Gulch Project pipeline corridor diverges from the three-party pipeline corridor and descends the east slope of Davis Point for 1 mile (MP 33). It then follows the west side of an existing private road owned by Exxon Corporation and progresses south along the Parachute Creek valley for approximately 1.5 miles. Near the base of Davis Point, the corridor crosses the Exxon road and the Middle Fork Pazachute Creek to enter a meadow and proceed south for another one-half mile. The pipeline corridor then crosses the East Fork Pazachute Creek and Garfield County Road 215 (MP 35) before' continuing south along an existing Unocal pipeline comdor. It stays east of Garrfield County Road 215 for approximately 2.5 miles before crossing it (MP 37.5) anti continuing south for another 6 miles to the Parachute Site. The Yankee Gulch Project includes approximately 20 miles of pipeline corridor on public land administered by the BLM and approximately .!4 miles on private lands. Land ownership by county is listed in Table 1-1. Approximately 35 miles of the 44-mile-long Yankee Gulch Project pipeline corridor pazallel existing pipeline corridors. The general categories of land ownership near the pipeline corridor are illustrated on Figure 1-2. Aland schedule i:> also included as Attachment 1.
