He discussed the terms of the Water Quality Control Discharge Permit for the <br />site. Among the areas of concern were the discharge permit effluent parameters and the <br />fact that. some of these levels were lower than concentrations allowed in drinking water. Mr. <br />Holmer explained that the permit parameters are set by the stream segment standards <br />adopted by the Water Quality Control Commission. Some aquatic species can be damaged <br />or eradicated by levels far below human tolerance. <br />Next Mr. Holmer explained the practical analytical quantitation limits for some of the <br />effluent parameters as listed on the discharge permit. If the analytical lab that is used by <br />the permittee cannot achieve the levels listed, there is a mechanism for determining a <br />suitable alternative level or identifying an improved technique that will be acceptable to <br />CDH, Mr. Holmer provided the names of several of the staff at the CDH lab who could <br />assist in initiating this process. <br />Finally, the appropriateness of WET testing requirements was discussed. This requirement <br />is based on the by federal program minimums; i.e, if CDH and Colorado wish to retain the <br />delegation of the water quality permitting and enforcement programs within the state, this <br />a requirement that must appear in the permits drafted. <br />
