The majority of the King Coal Mine was previously mined and not reclaimed to the <br />requirements of the Colorado Surface Coal Mining Reclamation Act (34-33-101 et <br />seq.). The only azea disturbed subsequent to the initiation of the permanent <br />program was a portion of the waste pile comprising 1.08 acres. As such the <br />revegetation of the King Coal Mine will be designed and implemented to conform to <br />the requirements of Rule 4.15.10. The revegetation measures will be undertaken to <br />provide and establish a cover of living plants supportable by the best available <br />suitable material in those areas of the mine re-affected by disturbance subsequent <br />to the permanent program, with ground cover not less than that existing prior to re- <br />disturbance and satisfactory to control erosion. <br />Grazing will be prevented in the reclaimed azea for a period of at least three <br />years to allow a successful establishment of vegetation. <br />The disturbed azea will not be ready for reseeding until the mine is <br />abandoned, graded and covered with plant growth medium. The access road will not <br />be reclaimed. It will provide access to the reclaimed area for fire control, reclamation <br />work, and inspection. After the coal and mine rock surface layers have been scraped <br />up and used for backf"ill, no tonic forming materials will seriously inhibit plant <br />growth. <br />After grading and re-contouring the mine bench and covering the area with <br />suitable plant growth medium, the disturbed area will be reseeded on slopes ranging <br />from less than 3:1 to2:1 on the highwalls. <br />After placement and spreading of plant growth medium, samples will be taken <br />and forwazded to a soil laboratory for analysis for major plant nutrients and <br />restrictive ions. Upon receipt of the test results and recommendation by testing <br />laboratory, the correct amount of fertilizer will be applied. <br />Plant growth medium preparation will be accomplished by using a disk or <br />harrow capable of disturbing the soil to a depth of 4". In case of a loose seed bed, a <br />cultipacker to firm the ground will be used following drilling. <br />On slopes of 3:1 or less the seed should be planted with a drill equipped with <br />double disc openers and depth bands. Spacing of discs should be no more than 10". <br />Seed should be planted to an approximate depth no deeper than 1/2". On slopes of <br />3:1 or greater, broadcast seeding may be used. Planting of seed will occur between <br />October 15 and April 30, or between July 15 and August 30. <br />Upon completion of drill seeding, all areas will receive two (2) tons of hay or <br />straw mulch per acre. The material is to be applied in an even manner by use of <br />hand mulching or a mechanical blower. On 3:1 slopes or less the mulch will be <br />crimped into the soil by use of a straight blade crimper of spacing of not more than <br />10". <br />Since no pre-disturbance vegetation data was collected, the following re- <br />vegetation success standards are based on SCS Range site data and baseline data <br />from similaz azeas. <br />• Total Live Vegetation Cover equal to or greater than thirty (30) percent. <br />National King Coal, LLC King I Mine <br />Section 2.05.4 <br />Page 7 March, 2006 <br />
