2.05-82 Rev. 11/96- PR07; 04/06-PR10; 12/14- TR136, 04/24 – TR153 Annual Subsidence Report. Copies of all raw and reduced data from the monitoring program will be maintained on file at Mountain Coal Company's offices for public inspection during normal business hours. Air Pollution Control Plan Air pollution control of facilities at the West Elk Mine will be done in accordance with emissions permits issued by the Air Pollution Control Division of the Colorado Department of Health. A copy of each permit can be found in Exhibit 6. Fugitive Dust Control Plan Coal handling facilities are appropriately equipped to minimize dust generation. All conveyors outside the mine portal are suitably covered to prevent particulate dispersion of coal by the wind. Water sprays, using surfactant as necessary, are mounted so as to prevent dust generation from conveyors or coal stockpiling, if needed. A telescoping chute is used in loading railroad cars at the loadout to help prevent dust generation. Finally, all transfer points between conveyors, rotary breakers, and silo(s) are enclosed to control particulate emissions from these sources. Mountain Coal Company also tries to minimize fugitive dust from roads at the West Elk Mine. Water is applied seasonally to active unpaved roadways, parking areas, and refuse disposal areas to control dust emissions from these areas. In addition, vehicle speed is restricted to a maximum of 20 miles per hour. Whenever these steps are insufficient in controlling fugitive dust emissions, chemical dust suppressants or surfactants are applied to road surfaces. Fish and Wildlife Management Plan The baseline wildlife information collected on the property indicates that the mine facilities area is not of prime significance to major wildlife species. The affected area is not know to be critical habitat for big game, raptors, eagles, migratory birds, any threatened or endangered species, or to contain wetlands, cliffs supporting raptors and/or areas offering special shelter, protection, reproduction, nursery or wintering areas. Using the best technology currently available to the extent possible, disturbances and adverse impacts of these operations on fish, wildlife, and related environmental impacts are minimized. Where practicable, enhancement of such resources is achieved. In so doing, Mountain Coal Company will report to the Division the presence of any threatened or endangered animal or plant species listed or proposed to be listed by the State or Secretary of the Interior; any critical habitat of any threatened or endangered animal or plant species listed or proposed to be listed by the State or Secretary of Interior; or any bald or golden eagle, or nest thereof, of which Mountain Coal Company becomes aware and which was not previously reported to the Division. The design and construction of the electric power lines and other transmission facilities used for its underground coal mining operation on the permit area will be designed and constructed to prevent hazards to large birds either by spacing of wires or by protectors. All powerlines at the West Elk Mine are raptor protected in one of two ways:
