EXHIBIT 5 The locations of the 25 shrub density transects sampled on the Greasewood Predisturbance Area are shown on Map 3, Permit Area Vegetation Map. Examination of the sample adequacy calculations in Table 2.04.10 -2, Loadout Area - Sample Adequacy Calculations, reveals the number of samples required to describe the shrub density on this area at the 90 percent confidence interval was 135.6 transects. INDUSTRIAL Located in the area between the old refinery located on the east side of the site and Reed Wash, is an area corresponding to the Industrial Vegetation type. These areas are almost totally devoid of vegetation and consist of barren refinery sludge or evaporation ponds, or constructed berms or dikes, roads and excavated barrow areas. For all practicable purposes these areas lack a defined vegetation plant community and the only plants which can be found growing on these areas are a few Greasewood plants, Cheatgrass, Purple Mustard and other weedy annual species. There is only very limited vegetation found on these areas The total area of the Industrial vegetation type as shown on Map 3, Permit Area Vegetation Map, is 87.13 acres and this type equals 41.82 percent of the proposed loadout study area and 40.5 percent of the permit area. Very limited disturbance, consisting of a proposed railroad loop is proposed for this area. There will be a substantial amount of disturbance planned for this area, but since the exact design is currently unknown. In the pre - consultation meeting held with Mr. Dan Mathews, he acknowledged that this vegetation type actually corresponding more closely to a land use rather than an actual vegetation type and as such it would not be necessary to perform actual vegetation sampling of this area. IRRIGATED WETLAND To the west of Reed Wash and to the east of Loma Drain, downslope of the existing Irrigated Pasture and Cropland areas located to the north of the proposed Loadout Permit Area are several areas dominated by wetland vegetation that appears to exist as a result of extensive flood irrigated practices conducted upslope of the proposed Loadout Permit Area. The total area of the Irrigated Wetland vegetation type as shown on Map 3, Permit Area Vegetation Map, is 19.17 acres and this type equals 9.20 percent of the proposed loadout permit area. Very limited disturbance, consisting of a proposed railroad loop is proposed for this area. The approximate amount of disturbance planned for this area is 0.95 acres, and will be less than 5 percent (10.42 acres) of the proposed Loadout Permit Area. As a result of this very small area, this type would technically correspond to the definition of a minor vegetation type as defined in the CDRMS Vegetation Guideline. In the pre - consultation meeting held with Mr. Dan Mathews, he acknowledged that this vegetation type would correspond to a minor vegetation type as defined in the CDRMS Vegetation Guideline but requested that a minimum of at least five transects be sampled in these areas. The results of this limited sampling are presented below. 12
