The refuse material has been removed, creating a small <br />valley in which Reach 13 flows, and separates the LRDA from the adjacent Clear Water Ditch. The sloping in the <br />valley is approximately a 3H: 1V and is in excellent condition. Reach 13 has been re-established in the bottom of <br />the valley and rock lined to prevent erosion. The newly restored area appears to meet the design specifications and <br />is in excellent condition. This area can be seen in Photos One through Three. Additionally, the Operator has <br />installed large boulders along the shoulder of the re-worked area as roll over protection. Immediately up gradient <br />of the valley, Reach 13 continues up to its beginning. The drainage is free from obstruction and able to function as <br />designed as seen in Photo Four. Also visible in photo Four is the re-sloping of the east end of the LRDA. The <br />sloping ties into the access road leading to the Upper Refuse Disposal Area (URDA) and appears stable. <br /> <br />Also observed were the recently re-established sections of Reach 10 that flow along the South and West sides of <br />the LRDA. The drainages have been re-established and tied in to the section that parallels the access road. The <br />sections adjacent the LRDA are free from obstruction and appear to meet design specifications. The section that <br />parallels the access road is also in good condition, and has had rock check dams installed to aid in erosion <br />prevention. The observed section of Reach 10 can be seen in Photos Five through Seven. All of the re-established <br />drainages appear to be able to function as designed. With the completion of these maintenance items, all drainages <br />are back to their approved design to shed water away from the LRDA. <br /> <br />The surface of the LRDA has been graded and compacted. In addition to the email delivery, the density test <br />results for the surface and the reworked area were provided to the Division upon arrival. All test results appear to <br />meet and or exceed the design requirements and the surface of the pad is in excellent condition. The surface of the <br />pad can be seen in Photo Eight. <br /> <br />The Upper Refuse Disposal Area (URDA) was also observed at the time of the inspection. During the inspection <br />the out slope of the area along the access road was being relaxed back to a gentler configuration and compacted. <br />The slope is being laid back to aid in erosion prevention of the face during significant rain and snowmelt events. <br />The out slope can be seen in Photos Nine and Ten. This area appeared stable at the time and the work is almost <br />completed. The surface of the pad was actively being watered at the time to prevent fugitive dust. A small <br />stockpile of material is located on the east end of the pad, and is staged for final placement once the sloping is <br />completed. Overall the URDA is in excellent condition. <br /> <br /> <br /> <br />
