Mr. Joseph Dudash - 2 - April 25, 2001 its destruction, no water could be bailed from this hole due to alignment problems. With no available water, no field parameters can be established. AW-2 is perennially damp, with no available water for bailing. DH-57 is dry, water found during the initial monitoring could have been residual water from its installation. DH-58, and DH-58a were initiated during 1999 and present only initial values. The 2000 AHR presents baseline values for DH-58 and DH-58a, though the sampling cycle is too short to consider these baseline values complete. 2. In the monitoring point tables presented in the 1999 AHR for surface water and ground water sampling sites, there are severs! required chemical parameters that are missing from the full suite baseline and full-suite regular hydrologic monitoring. Please explain. The ACZ Laboratories lab analyses sheets leave blank fields for parameters that were tested but found to have less than the Method Detection Limit (MDL) value. The monitoring point tables have now been revised to indicate "<MDL" for pazameters that were tested for but found to have less than the Method Detection Limit value. These MDL values aze now listed on the monitoring point table, in the column describing the parameter. Blank fields on the monitoring point tables now indicate pazameters that were not tested for. • 3. There are quite a few monitoring point tables in the 1999 AHR that do not have baseline ~ data listed, although the footnote on each table page states that there is baseline data. Please update the monitoring point tables to show the baseline data. The Operator feels that the absence of water, and therefor the absence of baseline values is an accurate reflection of the baseline of a monitoring point. 4. In Table 1 of the 1999 AHR, the frequencv of full suite measurements for surface water streams and ditches and ground water wells is listed as being semi-annual. However, the approved hydrologic monitoring plan, found on pages 1.05-76, 77 and 2.05-78 of the permit application, states that the monitoring is to be in the second and jotrrth quarters. In order to avoid confusion, please add a footnote to Table 1 that states that the semi- annual full s:~ite analyses are to be in the second and fourth quarters. The footnote has been added to Table 1. 5. In Table 1 of the 1999 AHR, for the upper and lower Fire Mountain Canal stations, the frequency of measurements for field parameters is listed as being quarterly and the full suite is listed as being semiannual. However, the approved monitoring plan, on permi! application page 2.05-77, states that the field parameters are to be obtained in May, Jttly and September, while the full suite analyses are to be performed in May and September. . For the sake of clarity, please add a footnote to these two items itt Table 1, stating the months that sampling is to occur.
