This report <br /> addresses deficiencies in the Detection Monitoring Program (DMP) in the vicinity of the Class <br /> II Surface Impoundments. <br /> The report is adequate and provides the minimum information required by the Monitoring Well <br /> Installation Guidelines attached to the Regional Water Boards 13267 order. However, staff <br /> regards the report as incomplete because it does not have a discussion on the newly installed <br /> wells borehole geophysics. The report contains geophysical logs of each borehole in <br /> Appendix C, but no interpretation or evaluation of the results from the certified geophysicist. <br /> Staff requests the Discharger submit a letter addendum to the.Report containing the required <br /> information by,12 January..2007, before the.Report will be considered complete. <br /> In a letter dated 17 November 2006, staff had recommended Interim Water Quality Protection <br /> Standards (WQPS) for the deep groundwater zone using the data set from the Regional Well. <br /> The WQPS utilized the mean plus one standard deviation for the constituents of concern. <br /> Standard protocol is two standard deviations. The WQPS presented below incorporate the <br /> mean plus two standard deviations.
