CC&V Wildlife Protection Plan S&ER Department THIS DOCUMENT IS UNCONTROLLED IN HARD COPY FORMAT Doc Id: NNA-CCV-ER-Plan - E_042 CCV S&ER Date of This Issue: 2/20/2019 Date of Next Review: 2/20/2022 Page 3 of 13 Attention shall be given to periods in the life cycle of those species, which may require special consideration (e.g., elk calving, migrations routes, and peregrine falcon nesting). The following Wildlife Protection Plans provides the procedures that CC&V uses to ensure wildlife safety and compliance with Colorado Mineral Rules 6.4.21(18) and 3.1.8(1). As defined in CC&V’s Operating and Reclamation Cresson Project Permit M-1980-244, the post-mining land use for CC&V has been established and approved as wildlife habitat and livestock grazing (rangeland). The purpose of this plan is to ensure wildlife safety during current mining practices and to prepare the site to meet the post-mining goals. CC&V’s Sustainability and External Relations (S&ER) Department manage this plan; however, it applies to all employees and contractors at CC&V. 2 Preventive Measures within Respective Areas of Activity 2.1 Lined Ponds • Lined ponds must be fenced to exclude wildlife. Fences will be a minimum of eight feet high with openings no larger than three inches in diameter in the bottom three feet unless sufficient justification exists to consider an alternate design. • Gates in fenced areas shall be designed to achieve the same protection as detailed above. For example, when the gates are closed, gaps, such as those below and between the gates, shall be less than three inches in diameter. • Gates on fenced areas must remain closed and be posted with signs indicating the same. CC&V’s approach is active management of process solution ponds to maintain WAD cyanide solutions below lethal concentrations for wildlife, which are 50 mg/l per the International Cyanide Management Institute guidance. Additional management methods include, but are not limited to, bird balls, netting, and/or other deterrents. 2.2 Active Leaching or Process Facilities – (>50 mg/l WAD cyanide concentration) Exclusionary measures shall be taken as needed to deter wildlife from inhabiting the area. Such measures include: • Areas of standing process solution shall be minimized and if observed must be corrected as soon as reasonably possible. Wildlife deterrence methods such as bird balls and netting might be used on these areas until standing solution can be mitigated. • Prior to drip line placement, the top lift is leveled and subsequently ripped after placement of ore. Side slope drip lines may be secured to keep drip lines in place. • Conduct routine evaluations of the process solution distribution network within the leaching facility to minimize standing solution. 2.3 Mine Area, and Other Excavations or Disturbances If obvious habitats and/or young, such as nests, eggs, calving areas, pups, or dens, are found when entering new areas for development, the findings should be reported to the CC&V S&ER department to ensure appropriate procedures for removal, avoidance, and/or relocation are followed.
