Notes
(1) Based on actual mining activity from 2015-17.
(2) Equals column (1) * Total Washed Material Mined.
(3) Equals column (1) * Total Unwashed Washed Material Mined.
(4) Equals column (2) * Moisture Content (washed)* (2000 / 62.4) / 43,560 + Column (3) * Moisture Content (unwashed) * (2000 / 62.4) / 43,560.
(5) Gravel operation dust control projected figures based on increase from previous years
(6) Granite quarry dust control; expected beginning January 2018
(7) Equals column (4) + column (5) + column (6).
(8) Taken from Table No. 1, Column (7)
(9) Total Depletions equal Column (7) + Column (8).
