DEPT, OF NA1UN.il P.LSOUkCES <br />December 19, 1980 <br />Mr. Robert Little <br />Hydrologist <br />Colorado Department of Natural Resources <br />Divison of Mine Lands Reclamation <br />1313 Sherman Street <br />Denver, CO 80203 <br />Dear Mr. Little: <br />As I indicated to you in our telephone conversation today, <br />we have had a communication problem with our consultant that <br />was doing the design for the sedimentation pond at the truck dump <br />area at the Snowmasa Coal Company unit train loading facility. <br />I have attached a copy of their calculations and the preliminary <br />design for the pond. As you can see, their design would have put <br />the pond on tlTe steep bluff below tlTe dump facility. The pond would <br />have served the purpose, but the destruction of vegetation and <br />damage to the hillside would have been much greater during the <br />construction of the pond than we feel is acceptable for the area. <br />I have instructed tiTem to design the pond that would be located <br />in the area that I have marked with an asterisk. They have indicated <br />they could not possibly complete this design properly by December 19, <br />1980, the abatement date whiciT you had specified in your correspondence <br />with the Snowmass Coal Company. They have, however, indicated that they <br />can complete the design in final form by December 24, 1980. I <br />would like to repeat my request to you to extend the abatement date <br />until December 24, 1980 so that the work can be done properly. We <br />would appreciate your approval on this extension. <br />We believe that if the weather cooperates we can complete <br />the construction on this sedimentation pond and control the water <br />within the disturbed area within 30 days after your approval of the <br />final design. <br />We sincerely appreciate your indulgence in this matter. <br />Sincerely yours, <br />James K. Greenlee <br />Director of Underground Mining <br />,. <br />JKG:lu <br />Encl. <br />cc: S. Se 1f and J. Feldstein <br />
