• APPROVED HYDROLOGICAL MONITORING PROGRAM <br />Table 2.04.7-1 summarizes various current approved monitoring sites. They are shown on Map <br />2.04.7-1A. For New Horizon 2 Mine, the sites are based upon recommendations made by <br />Greystone Consultants and subsequent revisions requested by WFC.The monitoring plan <br />revised as per TR38 will be adequate for the Garvey and Burbridge leases included in the <br />permit boundary and other mining areas to the west-northwest that WFC intends to include <br />within the permit boundary in the near future. TR-47 resumes the monitoring of wells GW-N16, <br />GW-N17 and GW-N18. <br /> <br />• <br />Map 2.04.7-1A shows the locations of surface stations and wells for the New Horizon Mine 2 <br />monitoring program. Modifications to the existing monitoring locations for surface and <br />groundwater are discussed below. All data will be reported in the annual hydrology report, <br />Map 2.04.7-1A has been updated to distinguish among the active and non-active wells for both <br />New Horizon Mine areas #1 and 32. <br />Also, Attachment 2.04.7-4 is included to provide the status and baseline data for all ground <br />water monitoring wells for both New Horizon 1 and New Horizon 2. <br />TABLE 2.04.7-1 <br />NEW HORIZON MINE <br />HYDROLOGICAL MONITORING PROGRAM <br /> MONTHLY QUARTERLY SEMI- <br />ANNUALLY ANNUALLY <br />NEW HORIZON 2 MINE February, May, <br />Au ust, Nov February , <br />Au ust August <br />GW-N16P1 Underburden Field 5 Lab 6 <br />GW-N17P1 Dakota Coal Field 5 Lab 6 <br />GW-N18P1 Overburden Field 5 Lab 6 <br />GW-N39 Alluvium Field 5 Lab 6 <br />GW-N40 Alluvium Field 5 Lab 6 <br />GW-N41 Overburden Field 5 Lab 6 <br />GW-N42 Coal Field 5 Lab 6 <br />GW-N43 Underburden Field 5 Lab 6 <br />GW-N44 Overburden Field 5 Lab 6 <br />GW-N45 Coal Field 5 Lab 6 <br />GW-N46 Underburden Field 5 Lab 6 <br />SW-N102 (NPDES 007) Field 2 Lab 3 <br />NPDES 008 Field 2 Lab 3 <br />NPDES 009 Field 2 Lab 3 <br />NPDES 011 Field 2 Lab 3 <br />
