Notes:
(t) The exposed area associated with the dewatering ditch will change as additional areas are exposed for mining It is assumed that the dewatering ditch has a maximum width of 5 feet
(2) Total gross evaporation (3 65 feet) is based upon NOAA Technical Report NWS 33 and distributed according to SEO Senate Bill 89 -120 criteria
November: 4.0% February 3.5% May 12 0% August 13 5%
December. 3.0% March 5 5% June, 14 5% September 10 0%
January 3 0% April- 9 0% July. 15 0% October. 7 0%
(3) Equal to (1) x (2)
(4) Based upon the average precipitation at the Greeley IJNC, CO (ID #3553) NOAA weather station for the nine period 1967 -2010
(5) Assumed 70% effective precipitation. (5) is equal to (4) x 70%
(6) Equal to (2) - (5).
(7) Equal to (I c) x (6).
(8) Evaporative depletions in (7) lagged using the Glover methodology in the IDS AWAS model using the following parameters -
Transmtsstvlty 120,000 gallons /day /foot
Specific Yield 0.2
Aquifer Width. 2,497 feet
Distance from center of pits to river 333 feet
(9) Projected future aggregate production from mining is based upon information from Martin Marietta Materials (MMM). Monthly production values are estimates and may vary so long as annual consumption is not exceeded
(10) Projected future aggregate production from mining is based upon information from Martin Marietta Materials (MMM). Water removed with mined aggregate equals 9 6 gallons/ton (4% of total mined volume) as defined by Senate Bill 89 -120.
Therefore, (10) is equal to the projected aggregate production (in tons), multiplied by 9 6 gallons /ton, divided by 325,851 to convert gallons to acre -feet.
(11) Lagging of production use in (10) based upon the factors shown in (8)
(12) Equal to (8) + (I 1).
