STATE F COLON III IIIIIIIIIIIII III <br />O v <br />Roy Romer, Govei <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTON, Director <br />February 18, 1987 <br />Mr. Jim Kiger <br />Senior Reclamation Specialist <br />Colowyo Coal Company <br />5731 State Highway 13 <br />Meeker, Colorado 81641 <br />Re: 1986 Revegetation Report, Hayden Gulch Mine, C-80-003 <br />Dear Mr. Kiger: <br />The Division has reviewed the 1986 Revegetation Report, submitted on <br />February 11, 1987, by Morrison Knudsen. Table 7, showing weighted averages of <br />cover and diversity data looks very positive, despite limited diversification <br />in the 1979-1980 and 1981 areas. <br />lJe would appreciate it if future reports would include the following <br />information: <br />A) The seed mixture used in 1984. The Division has a minor revision <br />for seed mixture change on file from January, 1986, and the staff <br />assumes that the seed mixture used during the 1981-1983 period was <br />also used in 1984; <br />B) Legible raw data sheets. Reproduction was very poor and it was <br />impossible to identify species or verify statistics; <br />C) An update of the species list (Table 4); <br />D) Correction of the Reclamation Sequence Map. This map indicates that <br />the topsoil piles were seeded in 1987, when they were seeded in 1986. <br />The Division expects to receive the 1987 Revegetation Report as part of the <br />1987 Annual Report, in February, 1988. <br />Sincerely, <br />~~~~~'r%~ G~~~~-F> <br />Catherine W.
