The Planning-Engineering Department of Montrose County, CO has expressed an <br />interest in assuming the legal and reclamation obligations ofwell(s) GW-N1 and/or GW-N 1 P1 for <br />their use at the old county landfill. WFC will not close GW-N1 and/or GW-N1P1 if the County <br />provides adequate documentation tothe State releasing WFC from its' obligation forthewell(s) prior <br />to the scheduled closure ofthe otherabandoned wells. Monitoring wells GW-N3, GW-N4, GW-N4R <br />and GW-N27 will be left open, but not monitored until required by the State at some as yet to be <br />determined date.

Table 2.04.7-1 below shows the currently <br />approved hydrological monitoring program. Map 2.04.7-1 has been modified to show both the <br />abandoned wells and those where monitoring has been discontinued as per MR-52. <br />APPROVED HYDROLOGICAL MONITORING PROGRAM <br />Table 2.04.7-1 summarizes various approved monitoring sites. They are shown on Map 2.04.7-1-A. <br />For New Horizon 1 Mine, these sites include those approved under the permit previously held by <br />Peabody Coal and later revised by Western Fuels-Colorado. For New Horizon 2 Mine, the sites are <br />based upon recommendations made by Greystone Consultants and subsequent revisions <br />requested by WFC. The monitoring plan revised as per TR38 will be adequate for the Garvey and <br />Burbridge leases included in the permit boundary and other mining areas to thewest-northwest that <br />WFC intends to include within the permit boundary in the near future. <br />Map 2.04.7-1 shows the locations of surface stations and wells for the New Horizon Mine 2 <br />monitoring program. Modifications to the existing monitoring locationsforsurfaceandgroundwater <br />are discussed below. All data will be reported in the annual hydrology report. <br />(Revised 10/17/01) <br />2.04.7-37 <br />
