n Coal Refi <br />The survey and site inspection for the refuse facility pond <br />certificatin was conducted on July 25, 1984. <br />All inspection results were compared to the design presented <br />by Espey, Huston and Associates to MLRD in July of 1980 and <br />revised a number of times until approval on October 27, <br />1980. The initial designs are shown in Figure 13.3.5, <br />13.3.6 and 13.3.7 of the Modified Permit Application for <br />the Meeker Area Mines and Associated Facilities, Rio Blanco <br />County, Colorado. <br />I have special knowledge of the entire refuse facility area <br />because I was involved in some of the engineering revisions, <br />the permitting, the write-up of the construction project and <br />the supervision of the entire construction. <br />The following items were checked to see if they coincided <br />with the approved design: <br />1) Constructed elevations: The elevations listed below <br />were checked with a precision level and stadia rod: <br />-Dewatering pipe inlet <br />-Dewatering pipe outlet <br />-Top of Dam <br />-Bottom of Spillway <br />-Toe of Dam <br />-Bottom of Pond <br />All elevations were found to be wthin 0.1 or 0.2 feet <br /> of the design. <br />2) Width of Spillway Design: 8.5 ft. Measured: 8.5 ft. <br />3) Heigh t of Embankment Design: 5.0 ft. Mesured: 5.0 <br /> ft. at spillway location. <br />4) Slope of Dam Design: 2.SH:1.OV. Mesured: 2.SH:1.OV <br />5) Width of Top of Dam Design: 10 feet. Measured: 10.5 <br /> feet <br />6) Rip-Rap, Gabions, Filter Fabric Design: as shown in <br />Figure 13.3.5, 13.3.6, 13.3.7. Measured: see enclosed <br />report from Dale Pyle to Jim Herron on Dec. 29, 1980. <br />7) Topsoil and Vegetation Removal See report mentioned <br />
