r~ <br />No evidence of degradation of overburden groundwater downgradient <br />of the ash disposal is apparent. Well AMW-1 monitors the <br />undisturbed overburden downgradient of the ash disposal area. <br />pH in all wells shows a range which is within the baseline range <br />for pH. Metal concentrations also show variation within the <br />established baseline range. <br />The operator states in the AHR text that "CEC would prefer to <br />sample wells located on site. Currently, two wells (DH122 and <br />DH96) are monitored on private property not own by CEC. CEC <br />intends to cooperate with the Division and comply with all rules <br />and regulations in order to meet this goal". Given the fact that <br />I could not locate a section of the permit which outlines the <br />hydrologic monitoring plan, I have a concern that this statement <br />indicates an intention by the operator to reduce the monitoring <br />plan without Division approval. <br />The required monitoring plan should be outlined in the permit text <br />or appendices. Any changes or reductions in this plan must be <br />identified and approved by the Division via the technical revision <br />process. Possibly Shawn can help us determine if the plan exists <br />in the permit currently. <br />If you have questions or concerns, let me know. <br />
