<br /> <br />forth in Tables 1 through 4 of the "Basic Standards for Ground Water' or the ambient quality, whichever is <br />less restrictive. Upon establishment of points of compliance and numeric protection levels, a compliance <br />plan will also be required. Enclosed with this letter is a copy of the DMG's standard ground water <br />compliance protocol. <br />In addition to the ground water protection program discussed above for the newly proposed CKD disposal <br />area, the DMG will require that a ground water quality evaluation program be implemented for the existing <br />CKD monofill. The operator must provide a plan for the characterization of ground water quality <br />downgradient from the existing monofill. This plan will be subject to Division review and approval prior to <br />implementation. In the event that ground water contamination is detected, the limits of the contamination <br />will have to be investigated, and numeric protection levels and points of compliance established. Also, the <br />presence of ground water contamination below the existing monofill would necessarily trigger a review of <br />the design and operation of the newly proposed CKD disposal area. Conversely, if no contamination is <br />found below the existing monofill, such a finding would serve to ratify the conclusion in the "Hydrogeologic <br />and Geochemical Assessment" report that it is extremely unlikely water migrating from the disposal facility <br />would reach a drinking water supply. <br />c:\windows~ersonaf~ground water precepLS attachment.doc <br />
