(1) Conditions include:
Net pond evaporation from 26.0 surface acres of exposed ground water.
650,000 tons/year of aggregate mined at 4 percent moisture retainage loss equals 19.12 acre per year of water in product.
980,000 gallons of water used for dust suppression equals 3.01 acre-feeet per year for dust suppression.
80,000 cubic yards of concrete batching at 30 gallons per cubic yard plus 3 gallons per cubic yard for concrete truck washout after each delivery.
1,000,000 gallons of water used to wash out concrete trucks at day's end at 10 percent per loss equals 0.307 acre-feet/year.
100,000 tons of CDOt asphalt production using 3 galons per ton with a safety factor of two.
275,00 gallons of water used to wash 55 vehicles weekly for 10 months at 10 percent loss.
Three bathrooms (shop office and concrete batch plant)>
Landscape irrigation of approximatley 4 acrees of grass, shrubs and trees with sprinkler and drip systems.
(2) Lagged depletions after 5 years determined by Glover analysis with a transmissivity value of 180,000 gpd/ft and a storage coefficient of 0.18
