phosphorous, azsenic, cadmium, lead, iron (dissolved), manganese and zinc. Please <br />explain. <br />6. It is stated on monitoring point table 91 for drill hole DH-38 that the bailer became <br />• lodged in the hole. Is this hole recoverable so full suite analyses can be run? <br />7. On monitoring point table 94, it is stated that a foreign object in the hole prevented <br />sampling of monitoring drill hole DH-58. Is DH-58 still a viable sampling point? <br />8. The list of drill hole water monitoring locations in Table 1 of the 2002 AHR does not <br />contain all of the monitoring sites listed on page 2.05-76 of the permit application. The <br />missing sites include DH-16, DH-34C, DH-57, DH-57a and DH-67D. According to the <br />text on page 5 of the 2002 AHR, DH-57 and DH-57a were mined through in 2001. Are <br />there substitutes for these two wells? These two sites should be taken off of the <br />monitoring site list on permit application page 2.05-76 through a minor revision <br />submittal. Also through a minor revision, Map 9 should be revised to show that DH-57 is <br />no longer active. Finally, please explain why the other sites, DH-16, DH-34C and DH- <br />67D, were not sampled in 2002. <br />9. It appeazs that spring monitoring points S2-9 and 52-10 need to be added to Table 1 of <br />the 2002 AHR. These two sites were visited in 2002. Please revise Table 1 accordingly. <br />10. Through the minor revision process, please add ponds P33-10 and P33-11 to the list of <br />monitored sites on permit application page 2.05-81. <br />11. Permit application page 2.05-85 shows two chemical parameter lists for surface water <br />monitoring. However, Table 2 on page 11 of the 2002 AHR shows only list 1. Please add <br />list 2 to Table 2 of the 2002 AHR. <br />12. On monitoring point table 77 for the Fire Mountain Canal-low, please revise the data <br />entry error for the operational temperature. <br />2002 Bi-Annual Subsidence Report <br />13. Please add a discussion to the upcoming 2003 Annual Report concerning whether or not <br />the subsidence data collected so far support the subsidence predictions made in Exhibit <br />15 of Volume 3 and Map 27, "Subsidence", both in the pemut application. The <br />discussion should include the subsidence magnitude, the angle of draw, the aerial extent <br />of subsidence based on the mine plan (shown on Map 27) and the stability of the outcrop <br />barrier pillazs and partial extraction zones. <br />14. In future subsidence report submittals, please enlarge the Subsidence Map, Map 27, <br />attached to the report. At the present scale, details aze very hazd to see. <br />2 <br />
