Transit Mix - Grisenti Gravel Pits
Projected Depletions from Nlining Operation (2015-2016)
Notes,
111 Production projections based upon Transit Mix's projected maximum annual production.
[2] Based upon 4 percent water loss by weight.
131 Dust control projections based upon historical maximum monthly pumping, distributed uniformly through the year
141 Based upon NOAH Evaporation Atlas (45.4 inches per year). distributed monthly based upon State's SB -120 guidelines.
151 Based upon average monthly precipitation data from the NOAA Climate Data (Canon Cnty, 1950 - 2003).
161 Effective Precipitation equals 70 percent of total precipitation, baud upon the State's SB -120 guidelines. [51.0.70.
171 Net Evaporation equals Gross Evaporation less Effective Precipitation, 141-16].
181 Exposed water surface area is currently 32.1 acres as measured from aerial imagery, and onsite measurements. •Ile mined area in Phase 2 is projected to
increase by 5 acres in 2015, and by another J6 acres in 22.4 Exposed water surface areas are conservatively estimated as 37.1 acres in 2015 and 42.1 acres in
19] Equals (71.181. `' .21`10
1101 Total Unlagged Depletion from Mining Operation equals 121 + 131 + 19).
1111 Total Lagged Depletions from Mining Operation are lagged using URF factors for each mining area, developed in IDS-AWAS employing the glover method. The
IDS-AWAS inputs arc provided in the 2012 SWSP request.
