C~ <br /> <br />CF&I STEEL CORPORATION <br />ANNUAL REPORT - SEPTEMBER 1982 <br />CANON DOLOMITE QUARRY <br />(1) The acreage affected during the period September 1981 to <br />September 1982 was 0.79 acres as shown on the enclosed <br />map. These acres are on benches previously disturbed by <br />mining. No new ground was disturbed during the mining <br />year. <br />(2)(3) There was no final reclamation in 1982. 1.40 acres <br />were graded, mulched, fertilized and planted in a Phase II <br />study to determine the most effective methods and species <br />for use. The test plots in the original quarry continue <br />to be monitored and this information was used for the 1.40 <br />acre Phase II study. <br />(4) Phase II was planted in Rabbit Brush, Yellow Sweet Clover, <br />Winterfat, Indian Rice Grass. Fourwing Saltbush, Ladak <br />Alfalfa, Lewisflax, Crested Wheatgrass, and Lutana Cicer <br />Milk vetch. The planting was done in March 1982 and the <br />fertilizer in April 1982. <br />(5) Na4N0 - 100 lbs, P205 - 150 lbs, K20 - 35 lbs <br />were ~roadcast. Lawn clippings were used for mulch during <br />the late spring and summer. <br />(6) Above average results in germination and biomass is <br />probably due to the above average rainfall during early <br />and mid-summer 1982. Supplemental watering will be used <br />in normal years to aid germination. <br />(7) An estimated 1.32 acres will be mined during 1983 and all <br />in areas previously disturbed.
