Table D -2 Uncompahgre Pit Mining Sequence
The mining schedule is planned to minimize disturbance by reclaiming areas as additional
mining is undertaken. This table is based on a reasonable projection of average production rates,
which can vary significantly. If production and sales increase to 200,000 tons per year, the mine
life is shortened to 52.5 years. The table shows that mining and reclamation will occur
approximately 105 years and the total gravel sold will be approximately 11 million tons. The
large size of this operation allows for the operator to plan for the future as well as the County
Planning Department to know there is a long term source of material in this portion of Montrose
County.
3. Mine Facilities and Operation
The crushing and screening will take place within the Mining Area 1. Fuel will be brought to the
site by a mobile fueling truck. On site fuel storage needs will vary depending on the plants that
are located on site at any one time. The mining, crushing and screening equipment will require a
single 3,000 gallon diesel tank which will be located near the crushing /screening plant as shown
on map C -2A. A 10,000 gallon tank will be located in the shop /office area as shown on Map C-
