LE 2 PERMITS <br />Within 60 days of the abandonment of a drill hole, approved drilling program or when requested by the <br />Division, the following information will be submitted: <br />a) Location of drill hole as plotted accurately on a topographic map. <br />b) Depth of drill hole. <br />c) Surface elevation of drill hole. <br />d) Intervals where water was encountered during drilling activities. <br />e) Diameter of drill hole <br />f) Type of amount of cement or other sealant used. <br />g) Name of drilling contractor and license number of rig. <br />h) How the hole was worked. <br />Exploration taking place inside and outside of the permit area will be handled through the Notice of Intent <br />(NOI) procedures. See the appropriate NOI for details for each program. <br />Water and Air Quality Control Techniques <br />Steps to be taken to comply with the Clean Water Act and other applicable water quality laws and <br />regulations and health and safety standards include a comprehensive drainage and sediment control plan <br />described in Section 2.05.3 and Sections 4.05.1 through 4.05.18. With respect to compliance with the <br />Clean Water Act, Colowyo has a discharge permit from the Colorado State Department of Health under <br />the National Pollutant and Discharge Elimination System (NPDES) that will include all new discharge <br />structures constructed for the Collom area expansion. Compliance with this permit will serve to effect <br />compliance with the Clean Water Act and the Colorado Water Quality Control Act. <br />Colowyo, likewise, operates under several emission permits from the Colorado Department of Health, Air <br />Pollution Control Division. Fugitive dust control measures will be employed as an integral part of the <br />mining and reclamation operations. <br />Colowyo conducts air quality monitoring at the site in accordance with the requirements of emission <br />permits approved by the Colorado Air Pollution Control Division. <br />Details of pollution control measures are discussed in section 2.05.6. <br />2.05.5 Post -Mining Land Uses <br />Historically, the Collom area has been managed utilizing the principles of multiple -use and can be most <br />accurately described as Rangeland/Fish and Wildlife Habitat. Map 17 serves to identify both the pre and <br />post -mine land use designations. Colowyo is focused on re-establishment of the joint land use of <br />Rangeland/Fish and Wildlife Habitat post -mining. The land management staff of Colowyo, the BLM <br />and the Colorado State Land Board fully support Colowyo's approach to the re-establishment and <br />enhancement of multiple -use Rangeland/Fish and Wildlife Habitat focused on improved range condition <br />and the creation of wildlife habitat specific to sagegrouse brood -rearing. Copies of the correspondence <br />confirming these views have been included in this package and are identified as Figures 2.05.5-1, 2.05.5-2 <br />and 2.05.5-3 respectively. Much of the lower portions of the Collom area receive light to moderate <br />grazing pressure primarily from cattle but also some use by sheep herds. These lower elevations also <br />provide seasonal transition (migratory) habitat for big game, but more importantly offer breeding and <br />brooding habitat to indigenous sage grouse and sharp -tailed grouse populations. The higher elevations <br />receive slight to light grazing pressure from cattle, but more typically light to moderate grazing pressure <br />from sheep herds. These higher elevations also provide Spring and Summer habitat for big game, <br />especially local elk herds (Exhibit 10 Item 6). <br />Collom — Rule 2, Page 102 Revision Date: 11/16/16 <br />Revision No.: MR -166 <br />
