Groundwater <br /> <br />tests will be conducted to verify that <br /> <br />no significant contamination exists. <br /> <br />Discharges from the demineralizer, acids, <br /> <br />caustics and other chemically contaminated <br /> <br />waste liquids will be collected in a <br /> <br />neutralizing basin. These discharges <br /> <br />will be chemically treated before <br /> <br />discharging to the evaporation pond. <br /> <br />Rain water runoff from the coal pile <br /> <br />will be collected in a lined settling <br /> <br />pond by a drainage ditch collecting <br /> <br />system and then evaporated. <br /> <br />Since the proposed plant will not <br /> <br />discharge any process liquid into the <br /> <br />Yampa River, no discharge permit is required. <br /> <br />Although the storm drain system consti- <br /> <br />tutes an uncontrolled point source dis- <br /> <br />charge, no permit will be required for <br /> <br />this source unless the State of Colorado <br /> <br />or the Environmental Protection Agency <br /> <br />- 141- <br />
