Rob Zuber Page 4 May 5, 2016 summarized in the proposed text), which is approximately opposite to what has been drawn on Map 10B. Please address these issues and update Map 10B accordingly. CCC responded that: (1) W-95-15 (and DH -76-8) had been added to Map 1013; (2) All wells were correctly labelled on the map; (3) The potentiometric contour intervals had been incorrectly labelled. In attempt to locate W-95-15, and verify the locations of UL -95-45 and W-95-02, the Division referenced data from Exhibit 7, Item 21: In the Collom Project Pre -Feasibility Hydrology Report prepared by Water Management Consultants in August 2005, Table 5.1 gives a summary of pre- existing wells. The three wells in question are all listed, together with an x,y coordinate in feet. Although the coordinate system is not known, the coordinates should allow all three points to be located relative to each other — unfortunately this was not found to be the case, casting doubt on the validity of data in the table. As an alternative, the permit numbers of the three wells were taken from Table 2.04.7-44 and used to identify the wells in the DWR database. Each well has a UTM coordinate in that database, which were used to verify the locations of UL -95-45 and W-95-02 and show that W- 95-15 is located at the point marked as a surface water monitoring location on Map 10B. Please update Map 1013 to show W-95-15 as a groundwater monitoring location. An unrelated inconsistency which was noted on Map 1013 is also added to this item: please check the labeling of MWC-04-33 (it is shown as MWC-04-33(FS,H) on the map, but Table 2.04.7-38 and Exhibit 7, Item 21, Appendix 5A suggests that it should be MWC-04-33(FG,H) The requested changes were made to Map 10B. The response is sufficient. Rule 2.05.6(3) — Protection of the hydrological balance 78. The response is sufficient. 79. The response is sufficient M a. The response is sufficient. b.

FOLLOWING COMPLETION OF THE WORK, A MINOR REVISION WILL BE SUBMITTED TO UPDATE THE PERMIT APPLICATION PACKAGE WITH A COMPLETE DESCRIPTION OF THE WELL, AND TO UPDATE TABLES 2.04.7-38,-39, -40 AND -41, AND MAPS 10B AND 11C.
