REVEGETATION
<br />The majority of the King I 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 area 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 I Mine will be designed and implemented to conform to the
<br />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 area for a period of at least three
<br />years to allow a successful establishment of vegetation.
<br />The disturbed area 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 backfill, no toxic forming maten7als 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 forwarded 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 i5 and April 30, or between July i5 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 similar areas.
