<br />EXHIBIT D -MINING PLAN (continued) <br />• The following general information is provided regarding the application: <br />PROPERTY OWNER: Carol Ann Schmidt <br />APPLICANT: B&B Excavating, lnc. <br />• <br />REPRESENTED BY: Scott Hoover <br />MINE OPERATOR: B&B Excavating, Inc. <br />2. ist r <br />The site has historically been used for agricultural purposes. Grazing and hay production have been <br />occurring on the land for approximately 100 years. Irrigation has been used to improve hay <br />production. <br />3. GeoloEic Information <br />The material to be mined is located in the eastern part of what is know as the Eagle Basin (a late <br />Paleozoic depositional trough, 250 million to 600 million years ago). The Eagle Valley Evaporite, <br />shale and salt, is a formation of Pennsylvanian age (300 to 350 million years ago) that outcrops all <br />along the Eagle River from Dowd Junction to Dotsero. In the immediate area of the Eagle River, <br />terrace, stream and outwash gravels are superimposed upon the Eagle Valley Evaporite. These <br />gravels are unconsolidated deposits of Pleistocene age (0 to 10 million years ago). All or a major <br />part of the gravels are probably of fluvial origin. Overlying the gravels are thin layers of soil. This <br />particular sand and gravel deposit is the second terrace above the Eagle River and varies in <br />thickness from 25 to 40 feet. The average mineable thickness is approximately 30-35 feet. The <br />gravel is relatively clean and is overlain by a thin deposit of soil and subsoil of approximately 0.5 <br />feet to 3.5 feet thickness. Underlying the gravel is a shale zone which prevents water migration to <br />lower materials. This upper tier or terrace is dry except for the possibility of intersecting some <br />shallow irrigation seep flows which lead to springs in the central drainage. This is discussed in <br />• detail in the section on mine hydrology. <br />Carol Ann Pemut CDMG Application 7 <br />
