5_3 Wash plant operations <br /> A wash plant is not currently in place at the operation, but may be added at a future time. At such <br /> a time, a technical revision would be submitted to DRMS. <br /> 5.4 Concrete batching <br /> No concrete plant is currently planned at the Hayden Gravel Pit, but Connell Resources <br /> maintains the option to add it in the future. At such a time, a technical revision would be <br /> submitted to DRMS. <br /> 5_5 Asphalt plant operation <br /> The asphalt plant uses water only during production of CDOT highway asphalt mix with lime. <br /> This is estimated to be 15 days a year for about 20,000 tons per year. This comes out to about <br /> 80,000 gallons or 0.26 acre feet per year. <br /> 5.6 Potable water for drinking <br /> Potable drinking water is estimated to be 50 gallons per month, but this water will be purchased <br /> commercially and will not be considered in the consumptive use calculations. <br /> Hayden Gravel Pit G_4 V/ GM I�icki and n�ia�.PLIA <br /> May 2020 _ _-\ <br />
