0 2. Mining Timetable
11
The following table (Table D-2) is a best estimate of the sequence of operations for the life of the
mine and is based on mining and selling an amount of 30,000 tons per year.

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. The table
shows that mining will occur over approximately 16.0 years. This timeline is based on the
maximum annual production of 30,000 tons of gravel. Shale mining will not be a determining
factor in production or mine life.
