Bruce Humphries <br />Mineral Program Supervisor <br />Mined Land Reclamation Division <br />1313 Sherman Street -Room 215 <br />Denver, CO 80203 <br />JUN 31993 <br />Division of Minerals d Geoio9y <br />RE: MLRD Permit No. M73-021, "Morrison Quarry East Highwall Remediation..." <br />Dear Mr. Humphries: <br />Enclosed is the report and drawings referenced above. The report contains an "interim" (or, <br />possibly final) mine plan for re-mining and stabilization of the east highwalls in the central <br />pit of the Morrison Quarry. This mine plan is in response to Cooley Gravels' need to re- <br />mine and stabilize this area of the quarry so that quarrying can continue deeper and to the <br />south as the current mine plan allows. This interim mine plan is also in response to Mr. Bill <br />York-Feirns inspection of October 16, 1992, my follow-up letter and request for <br />"emergency" administrative approval to extend the limit of disturbance to Mr. Carl Mount of <br />October 23, 1992, and your response to Cooley Gravel's request of October 28, 1992. <br />Due to the need for more adequate ground control (surveying and mapping) than was <br />currently in Cooley's possession, and poor weather, the mine plan and investigation was <br />delayed. Cooley is currently awaiting Jefferson County administrative approval to increase <br />the limits of mining 80ft. to the east. A copy of the letter to Jeffco requesting the <br />administrative zoning approval is enclosed for your review. <br />Upon Jefferson County approval, re-mining of the eastern quarry will commence exactly as <br />the report recommends. Also, upon Jeffco approval, the appropriate amendment describing a <br />revised mine and reclamation plan will be submitted to the Division as per Bill York-Feirn's <br />condition in his report of April 20, 1993, which I received on May 24, 1993. Cooley hopes <br />to meet the June 30 deadline for this amended mine and reclamation plan for the central and <br />south areas of the Morrison Quarry, as also requested in Mr. York-Feirns' letter. Cooley <br />Gravel understands the need to clarify the existing, amended mine plan for this area of the <br />quarry currently permitted under M73-021. There is a major discrepancy contained within <br />the 1982 amendment between the narrative describing mining and backfilling (including the <br />"profile"schematic) and the mine plan map. <br />- AN EQUAL OPPORTUNITY EMPLOYER - <br />Bituminous Roadways of Colorado.
