1.0 Introduction <br />1.1 Site Description <br />The Sunday Mines Group is a group of five existing underground uranium- vanadium <br />mines located San Miguel County Colorado, as shown in Figure 1 -1. The mines are <br />currently permitted under individual state permits, however the mines are located in <br />very close proximity, and all mines are operated by Denison Mines (USA) Corp. <br />(Denison). Therefore, Denison manages these operations as the Sunday Mines Group, <br />which includes: <br />• The Sunday Mine; <br />• The Carnation Mine; <br />• The St. Jude Mine; <br />• The West Sunday Mine; and <br />• The Topaz Mine. <br />The mines are located in southwestern Colorado approximately 17 miles southwest of <br />Naturita, Colorado. Specifically, the permit boundary of the Sunday Mines Group is <br />located in Sections 10,11,13 through 15, and 22 through 26, Township 44 North, <br />Range 18 West, New Mexico Principal Meridian, San Miguel County, Colorado. <br />Denison's closest local mine office is in Egnar, Colorado, located approximately 18 <br />miles southwest of the mine. <br />1.2 Purpose <br />The Colorado Division of Reclamation, Mining and Safety (Division) provided <br />Notices of Determination of Designated Mining Operation (DMO) to Denison on <br />February 8, 2008 for all five of the mines that encompass the Sunday Mines Group. In <br />addition, existing state mine reclamation law was modified by Colorado House Bill <br />(HB) 1161 on May 20, 2008. This new law expands the definition of a DMO to include <br />conventional uranium mines such as the Sunday Group mines. However, these rules <br />are being promulgated now, but are not currently in place. An environmental <br />protection plan (EPP) is required for all DMOs under current state law. Therefore, an <br />EPP has been prepared in accordance with existing laws and regulations for the <br />Sunday Group Mines. <br />The Sunday Mines Group is currently permitted as follows: <br />• The Sunday, West Sunday and Topaz Mines are 112d permits (regular operations) <br />with permit numbers of M- 1977 -285, M- 1981 -021 and M- 1980 -055HR respectively. <br />• The Carnation and St. Jude mines are 110(2)d permits with permit numbers of M- <br />1977 -416 and M- 1978- 039HR. <br />C \ Users \cwoodwardiDesklnp \Sundays \FINAL - Environmental Protection Plan Sunday Mines Revised January 2012 docx <br />1 -1 <br />
