Box 1821 <br />Colorado Springs, CO 80901 <br />RE: G.E.C. - Orphan Pit- Coal Revocation Project <br />RN-GOAL-MINES-8 <br />Dear Dr. Corley, <br />pF' CO~ <br />~~ 4 <br />~% b <br />~~ o <br />•~rB]6 ~• <br />Roy Romer <br />Governor <br />M¢hael B. Long <br />D ivwon Direcla <br />The Division received your letter dated August 26, 1993 regarding G.E.C.- Orphan <br />Pit- Coal Revocation Project (RN-COAL-MINES-8). In your letter to the Div iaion, <br />you suggested that there should be a change made in the reclamation plan of the <br />G.E.C. invitation and bid document. Per your recommendation, the Division has <br />developed a new reclamation plan for the Harrison Western area of disturbance. <br />The Division proposes to remove the West Pit sediment pond, and delete the task <br />of the West Pit Diversion. The undisturbed drainage ditch and the Weet Pit <br />drainage ditch would join above the pond and the ditch outflow will be below the <br />pond discharging into Magpie Creek. Please see the attached Field Directive for <br />further clarification and detail. Phil Kessler of Resaler's Reclamation has been <br />notified of this change, and a site inspection was conducted on September 10 by <br />Kessler and the Division. A cost estimate has not been reached between Kessler's <br />Reclamation and the Division. Once a cost has been determined, the Division will <br />notify all interested parties. <br />Also enclosed ie the information you requested regarding curve numbers for the <br />10 year, 24 hour event. I apologize for the delay in responding to your request. <br />Please review the following work narrative and issues any comments to the <br />Division ae soon ae possible. Phil Keaeler has been advised to conduct this part <br />of the reclamation work last to account for any last minute changes. Please call <br />if you have any questions. <br />Sincerely, <br />C <br />Erica S.
