Ready Mixed Concrete Company - Bromley Lakes Site
Depletions and Replacements (January - December 2015)
Proposed SWSP Operations
(all values in acre -feet unless specified)
[ 10] Total surface area of exposed ground water at Bromley Lakes Lot 2 is conservatively projected to be I acre.
[11] Net evaporation equals exposed ground water area multiplied by the net evaporation rate, [10] x [4]/12.
[ 12] Lot 2 production above and below the static ground water (GW) table. Since the exact timing of production above the GW table is not known, projections conservatively
show all production below the GW table.
[ 13] Wash water and aggregate moisture content equals 2% by weight for gravel mined above the ground water table and 4% by weight for gravel mined below the ground water
table.
[ 14] Total evaporation and gravel mining depletion equals [11 ] + [13].
[ 15] Bromley Lakes Lot 2 metered dewatering pumping to the McCanne Ditch.
[ 16] Dewatering pumping depletion is equal to the dewatering pumping in column [15] lagged over 5 months during the months that RMCC is not dewatering (i.e. when column
[15] equals zero). The lagging factors are given in the October 2014 SWSP request.
[17] Total lagged depletion equals the Bromley Lakes Lot 2 evaporation and gravel depletion in column [14] lagged over 5 months plus the dewatering pumping,depletion in
column [16]. The lagging factors are given in the October 2014 SWSP request.
[ 18] Total lagged site depletion for Bromley Lakes Cell 2 and Lot 2 equals [9] + [ 17].
