<br />EXHIBIT 2 <br />• <br />GEOPHYSICAL SOIL MOISTURE MEASUREMENTS <br />A geophysical soil moisture measurement study has been conducted in <br />accordance with Rule 2.06.8 of this application. Data have been col- <br />lected to document soil moisture conditions which exist within the <br />"unconsolidated stream-laid deposits holding streams" shown on Map 1, <br />Twentymile Park Hydrology, and Map 4, Energy Mine No. 3 Ground Water <br />Hydrology. Specifically, the data were collected to document, if pos- <br />sible, the presence of capillary water extending from the water table <br />upward into the root zone. The study was conducted in late summer <br />(October, 1980), at a time of year when the water table and capillary <br />fringe should be at their lowest levels. Thus, if capillary water was <br />found within the root zone at the time of measurement, the root zone <br />• could be determined to have a perennial water supply. <br />The soil moisture data were collected by taking measurements in <br />seven neutron probe access tubes with a nuclear soil moisture gauge. <br />The procedure consisted of drilling a two-inch auger hole through the <br />topsoil and the alluvium to the water table; setting a two-inch diameter <br />alluminum irrigation pipe in the hole, allowing the access tube to <br />settle for at least 24 hours; and logging the access tube from the <br />bottom up at six-inch intervals with the nuclear soil moisture gauge. A <br />lithologic description of each auger hole was obtained during drilling. <br />The seven neutron probe access tubes are located at sites shown on <br />Map 4, Energy Mine No. 3 Ground Water Hydrology, in the intermittent and <br />perennial streams draining the permit area. These locations are: 1) <br />Foidel 113, on the west bank of the lower reach of Foidel Creek; 2) <br />Middle 111, on the east bank of Middle Creek adjacent to Pit 3B South; <br />3) Middle 112, on the west bank of Middle Creek above the confluence with <br />• Foidel Creek; 4) Middle 113, on the east bank of Middle Creek adjacent <br />
