Notes
[ 11 ] Total surface area of exposed ground water at Bromley Lakes Lot 2 and the Plant Site is conservatively projected to be 4 3 acres through July 2014 and
I acre from August 2014 through December 2015

1131 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
[ 14] Wash water and aggregate moisture content equals 2 °o by weight for gravel mined above the ground water table and 4 °a by weight for gravel mined
below the ground water table
[ 151 Total evaporation and grovel mining depletion equals [ 121 • [15]
