® Ready Mixed Concrete Company - Bromley Lakes Site
Depletions and Replacements (January - December 2015)
Proposed SWSP Operations
(all values in acre -feet unless specified)
[ 1] Total surface area of exposed ground water in Bromley Lakes Cell 2 is conservatively projected to be 29.2 acres.
[2] Gross evaporation rate equals 44.5; inches (3.71 ft) per year, based upon NOAA Evaporation Atlas. Monthly distribution based upon SB -120 Guidelines.
[3] Effective precipitation rate equals 70% of total precipitation, based upon average precipitation at the Brighton weather station.
4 [4] Net evaporation rate equals [2] - [3].
[5] Net evaporation equals exposed ground water area multiplied by the net evaporation rate, [1] x [4]/12.
[6] Production from Kenneth Mitchell Lake 1 which is a slurry wall lined pit.
[7] Aggregate wash water depletion equals 2% by weight for gravel mined within a slurry wall lined pit. The wash water is pumped from Cell 2.
[8] Total evaporation and gravel mining depletion equals [5] + [7].
[9] Lagged site depletion equals the Bromley Lakes Cell 2 evaporation and gravel depletion in column [8] lagged over 12 months according to the Cell 2 lagging factors
given in the October 2014 SWSP request.
