Acid or Toxic Formic Materials <br />The material directly above and below the coal seams to be mined does not exhibit characteristics of acid or toxic <br />materials. Please refer to Section 2.04.6 Geology Description for detailed information. Water discharged from the <br />mines has historically been produced through the roof and floor rock; therefore, it is an indicator of acid/toxic forming <br />potential. Please refer to Exhibit 22, Mine Water Discharge Analysis, Section 2.04.7 Hydrology Information, and <br />2.05.6 Mitigation of Impacts of Mining Operations for additional information on mine water discharges. This <br />information substantiates that mine discharge water contains no known substances in concentrations which can be <br />classified as acidic or toxic. <br />2.05.5 POST -MINING LAND USE <br />The post- mining land use for the disturbed areas at the EC mine site have been previously discussed in the preceding <br />sections. Post- mining land uses are presented on the Reclamation Plan Map (Map 29). The post- mining land use of <br />the major affected areas along with their acreage is presented on Table 72, Post - Mining Land Use for Disturbed Areas <br />and Associated Acreage. <br />The final land use presented will be achieved by planting the sites with the appropriate seed mixtures and <br />implementing land management techniques consistent with the final land uses. The seeded areas will be monitored for <br />plant growth and reseeded if necessary, to meet the requirements of Rule 4.15, Revegetation Requirements. <br />The management practices to be used for each of the post- mining land uses will be consistent with the local <br />management practice for that use. For example, for those areas to be returned to cropland, the area will be cropped <br />every other year with the area lying fallow during the year in which it is not cropped. For those areas returned to <br />pastureland (irrigated hayland), the fields will be hayed a maximum of two times per growing season. If possible, the <br />hay fields will be utilized for either or both early spring pasture or fall pasture. Numbers of animals to be grazed will <br />be determined at the time the land is ready for grazing. Likewise, for those areas to be returned to rangeland/wildlife, <br />numbers of animals to be grazed on the site will be determined when the land is ready for grazing. No grazing will <br />occur within the first two -(2) years following seeding operations. A grazing plan, including area to be grazed, period <br />of grazing, and number of animals, will be submitted to the Division prior to initiation of grazing on reclaimed lands. <br />Letters to surface landowners concerning post mining land use have been included in Exhibit 26, Letters to Land <br />Owners. <br />2.05.6 MITIGATION OF THE IMPACTS OF MINING OPERATIONS <br />Air Pollution Control Plan <br />EC has implemented fugitive dust control measures as an integral part of all mining and reclamation activities. Air <br />Pollution Control Permits have been obtained from the Colorado Department of Health. Copies of these Air Pollution <br />Control Permits are available for inspection in Exhibit 2, Other Required Permits. <br />EC has implemented an air pollution control plan, which involves the utilization of BACT to control fugitive dust <br />from its operation. The primary dust suppressant is water used on the mine roads. EC has installed dust collection <br />systems and dust suppression sprays for all coal transfer systems at the mine, as well as covering the main conveyor <br />belt systems. Details of the coal handling system have been previously discussed under facilities in Section 2.05.3, <br />Operation Plan - Permit Area. <br />Fish and Wildlife Plan <br />During the development of baseline data for fish and wildlife information, no rare or endangered species were <br />Permit Revision 04 -34 2.05 -35.2 Revised 7/2/04 <br />
