Syracuse Wav Suite 217 Denver, CO 60231 (3031 696-6646 <br />April 30, 1985 <br />Mr. Jim McArdle <br />Mined Land Reclamation Division <br />423 Centennial Building <br />1313 Sherman Street <br />Denver, Colorado 80203 <br />RE: Cooley Gravel Company - Morrison Quarry; Permit No. 73-21 <br />Dear Jim: <br />The following report and map showing present status of the <br />Quarry hopefully will answer all questions of the August 8, 1984 <br />inspection. <br />Two areas on the North end have been reclaimed. The area at <br />the South end of the quarry has been backfilled and topsoiled. <br />Seeding will take place this spring. <br />- Sixty-eight acres are included in the total current distur- <br />bance on site. The plant site is approximately 10 acres. The <br />North quarry area is about 26 acres. The stockpile at the South <br />end of the quarry is being moved to the location marked future <br />stockpile at this time. The South quarry area is approximately <br />32 acres. Much of this area has not been disturbed but is <br />included in the 68 acre estimate. <br />In order to topsoil the entire 68 acres at a 12 inch depth, <br />109,707 cubic yards of growth medium are required. <br />The stockpile located at the South end of the quarry contains <br />200,000 tons of material. Using a conversion factor of 1.6 tons <br />per cubic yard, there are 125,000 cubic yards of growth medium on <br />site . <br />~~ <br />b <br />'t'i. i~~ ~,:l:SJ <br />... <br />. .~ <br />t.i ., .. ~ <br />Enpineerinp & Environmental Services <br /> <br />..• . <br />~d. <br /> <br />
