excess material resulting frorn swell of the total soil volurne excavated would <br />increase these depths somewhat. <br />Most existing vegetation would readily grow up through these minor soil coverings, <br />thus obviating the need for reclamation of such areas. Furthermore, because <br />excavated materials will be replaced in the trench more or less in the reverse order <br />in which they were removed, the "excess" are most likely to be somewhat reworked <br />topsoils and, as such, not "difficult to reclaim." <br />30. To quantify impacts to vegetation we need to know how they plan to clear the ROW. <br />How lazge of an area will be cleared to baze soil and how much of the 75-foot condor will still <br />have vegetation, albeit crushed vegetation? Will they make an effort to leave trees in place or will <br />they clear trees across the entire corridor? (This same type of information should be included for <br />the mining site.) <br />See our response to item 25, above. As indicated there, the desired construction <br />right-of--way width will be 125 feet. The only portion of that width that will <br />intentionally be cleared to bare ground will be the pipeline trench and the areas <br />immediately adjacent to it (about 10-12 feet). Substantial impact to vegetation will <br />also occur due to soil piling and equipment movement (up to about 20 feet on either <br />side of the trench for a total width of 46 feet, assuming a 6 foot trench). Where trees <br />and/or shrubs are present in the remaining portions of the pipeline right-of--way, <br />they will be cleared with a standard bulldozer. In general, it will be necessary to <br />remove all Yrees across the entire corridor to accommodate the construction <br />activities described in item 25. See Section 4 of "The Williams Companies Onshore <br />Pipeline Construction Specifications" (9 June 1997). <br />31. How many road crossings are there where the pipeline burial will be 4 feet deep? <br />There will be four road crossings that will require boring, located as follows: <br />• Piceance Creek; Section 28, TlS, R97W <br />• Collins Gulch; Section 16, T2S, R96W <br />• Piceance Creek: Section 32, T2S, R96W <br />• Parachute Creek; Section 17, T65, R96W. <br />The pipeline will be buried 4 feet deep at each road crossing, as required by DOT <br />specifications. The pipes will be placed in separate bores 10 feet apart under the <br />roads. The construction right-of-zvay will flare so~nezvhat to allow construction <br />activities at the road crossings. <br />18 <br />
