CNAPTERTHREE Emnronmem~u Consequences 3.2 SOILS 3.2.1 Direct and Indirect Impacts Piceance Site Impacts would be the same as those described for the Proposed Action, except for the following. The Yellow Creek Jeep Trail would be widened, instead of realigned. Disturt~ance of soils for road widening would affect about 3.7 acres, compared with 5.2 acres from relocation of the road under the Proposed Action. A stormwater retention pond would also be added to the Piceance Site. The pond would have 1 acre of pond surface, would occupy 1.6 acres i~tcluding berms and would require an additiona10.5 acres of short-term construction-phase disturbance. The net change from the Yellow Creek Jeep Trail and stormwater retention pond wotdd be an increase of 0.1 acre of long-term disturbance and 0.5 acre of short-term disturbance, botl~ on fragile soils. A more detailed Reclamation Plan has been prepazed and is included in AppE;ndix H of this Final EIS. It includes descriptions of proposed methods for erosion control (best management practices), surface water diversion and control, soil salvage and reconstruction, and revegetation. Soils salvaged during initial disturbance would either be immediately replaccd on lands requiring permanent reclamation or stockpiled for future use. Several seed mixtures are included, including a critical azea stabilization seed mixture for quick establishment of temporary cover, an interim revegetation seed mixture, and four permanent revegetation seed mixtures. • Pipeline Corridor Impacts would be similaz to those assessed for the Proposed Action. The proposed pipeline corridor has been modified in a number of azeas to improve constructability. The revised route generally follows the original route, and i,t would cross the same soil types and affect approximately the same acreages of the various soil types. The Pipeline Plan of Development (Section 3.4 and Attachment 6 of the plaza, Appendix F of this Final EIS) includes more detail regazding reclamation and erosion control than was provided in the Draft EIS. Topsoil would be removed from the entire 125-foot width of the construction ROW. Erosion control methods would include channel stabilization, diversion structures, water diversions, and mulch. Mulch would be applied to all azeas of highly erodible soils and in azeas with slopes greater than 15 percent. Excess rock excavated from Ute trench would be removed for use as riprap at streazn or washout crossings, buried on the ROW, or used as barricades to deter use of the ROW as a road. Erosion control fabrics would be applied on asite-specific basis to control soil erosion. Parachute Site Impacts would be the same as those described for the Proposed Action. The Reclamation Plan provides additional details about erosion control and reclamation procedures that would be • applied at the Pazachute Site. 3-2 Soils
