The <br />washer will be located Just South of the crushing, staging and <br />stockpile sites In Area II, as shown on Exh[bit C. Water will be <br />obtained from the Clty of Canon Clty through a tap and Dieter off <br />the existing water main In Tunnel Drive, and delivered to the <br />washer through a 2" P.V.C. pipe line installed alongside the main <br />haul road. Clean water will be stored at the washer !n steel, <br />above ground tanks with a maximum capacity of 10,000 gallons. <br />Water discharged from the washer will be placed !n a two-stage <br />sedimentation pond, with clear water being returned to the <br />storage tanks for reuse. Water lost through evaporation will be <br />replaced by water delivered by pipeline from the Clty water main. <br />This proposed washing operation will not directly affect any sur- <br />face or ground water system; therefore, no Construction Aggregate <br />Industrial Wastewater Discharge Pernlt will be required. It is <br />anticipated that aggregate washing will occur only during ap- <br />proximately 90 days per year, yielding approximately 20,000 tons <br />of washed product annually. <br />I[ you have any questions or desire additional information on <br />this matter, please don't hesitate to contact me. <br />S1 1y, jo° - ....mss <br />~~~~ ~- Mt1M'9El;t <br />IOi«~ <br />Charles R.
