NlLTON, Dinetor G T0: Joe Oliver ~/~~ ~~ FROM: Jim Pendleton DATE: October 24, 19 4 RE: Technical Revision Application -Eagle No. 5 and No. 9 Underground Coal Mines Empire Energy Corporation is requesting a technical revision to pursue the construction of an overland conveyer crossing of the Williams's Fork River and Colorado Highway No. 13/789. This construction will involve the construction of a temporary access road, laydown yard and the operation of a structural crane within the active channel of the Williams's Fork River. The construction of the tube conveyer enclosure will prevent coal fine pollution of the Williams's Fork River. For this reason, carefully controlled minor disturbance of that channel would appear to be warranted. However, the information presented by the applicant within the technical revision application is extremely vague in reference to the conditions within and atljacent to the channel of the Williams's Fork River. The temporary road and laydown areas would appear acceptable as proposed. As the applicant observes, a specific permit will be required from the Colorado Department of Highways, because the proposed disturbance lies within the highway right-of-way. The Division should condition approval of the technical revision upon receipt of the appropriate Colorado Highway Department Utilities Permit. The more critical component of this technical revision appli~ration involves the need for a crane to work within the channel of the Williams's Fork River while the conveyer enclosure tube is being placed over the river. It will be important to minimize disturbance to that channel and the adjoining areas. The applicant presents two access alternatives which include possible placement of fill as a pad for the crane or excavation of a ramp in the river bank. The scale of Map IV - 9 does not allow determination of the actual site configuration in the immediate area of the proposed channel disturbance. Applicant should provide the Division with a construction scale site map (perhaps one inch equals twenty feet) and an appropriate contour interval such as one foot. The applicant should indicate upon the map exa~~tly what envelope the crane would operate within. 423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel. (303) 868-3567
