Box 772129 <br />Steamboat Springs, Colorado 80477 <br />Att: Mr. Mike Kondelis <br />Subject: Quarterly Inspection <br />Excess Spoil Disposal Area I <br />Eckman Park Facility <br />Job No. 8569A <br />Gentlemen: <br />At your request, we made an inspection of excess spoil disposal Area I <br />on October 7, 1982• No spoil was being placed in the disposal area at <br />the time of our investigation and the top of the pile had been raised <br />very little since our previous inspection of June 1982. Haulage access <br />roads on the pile itself had been filled and the outslopes graded to <br />their design configurations. Topsoil was being placed along the out- <br />slopes. The Coal Company informed us that placement of spoil in this <br />area has essentially been completed. We were also informed that inter- <br />mediate slope benches had been graded to drain toward the inslope of the <br />pile. Benches have been graded to direct runoff toward the back or <br />east end of the pile where spoil abuts the natural ground surface. The <br />top of the pile was being graded to eliminate low spots which could result <br />in ponding of water. There was no evidence of slope failures at the time <br />of our inspection. <br />If we can be of further service in discussing the contents of this letter, <br />or our observations, please call. <br />Very truly yours, :.~::;. <br />CTL/THOMPSON, IN <br />,- ~ <br />By ~. ~ ~ 1 31 !~' fa <br />iam C. ` f ann,Jr. , P.
