On a map generated from the CO Division of Water Resources in the appendix of Exhibit C is shown water
resources, consisting of surface water and groundwater wells, within a specific local regime approximately within 2
miles of the proposed affected area.
6.4.20(8)(b)
There are no perched zones or traditionally defined aquifers known in this mountainous area. The site is completely
composed of crystalline Precambrian rocks, i.e. gneisses and schists, and tertiary intrusive rocks such as quartz
monzonites overlain by 0-24" of unconsolidated material.
Unconsolidated materials, soils, of between 0 and 18"-24" overlay the crystalline rocks. The rocks themselves have
essentially no porosity or permeability. Random, in-identifiable fractures due to jointing and faulting provide the
only groundwater transinissivity and relative porosity. The site is underlain by numerous mine openings, the most
. important of which is the workings of the Shaffer Mine. The vein of the Shafter Mine outcrops within 100 yards of
the proposed disposal area, strikes N 40-60° W and dips 78-80° NW. The Shafter vein (along with the Great
