The <br /> inspection was conducted and the report and photos prepared by me,Robin Reilley of the DBMS. <br /> Graham Roberts, Trapper Mine representative was present throughout the inspection. Skies were clear <br /> and temperatures ranged between 50 and 70 degrees Fahrenheit. Ash and coal were being hauled and <br /> spoil being transported and dumped. A blast was observed in the L dip pit,permit and blasting records <br /> were checked. <br /> OUTSTANDING MAINTENANCE ITEMS: <br /> Culverts <br /> o Previous inspections identified several abraded culverts along the main haul road. Some <br /> culverts were replaced in 2018 during the time a portion of the power plant was temporarily <br /> decommissioned (SA4). <br /> o Constructed drainages in parcel LA 18 exhibited compromised check dams, erosional <br /> features and the north facing slope had several significant rills and gullies across its extent. <br /> o A contour ditch and a check dam, in drainage MF2' was breached in parcel LA 18. This <br /> occurred at the transition between more established reclamation and the newly seeded <br /> LA 18 reclamation. <br /> NEW MAINTENANCE ITEMS: <br /> o Maintenance on the above previously identified erosional issues had not been completed <br /> due to spring conditions making slopes not safe for heavy equipment. <br /> o The crack noted in the previous month's inspection appeared not to have changed and <br /> vegetation had grown vigorously around the area. TMI will continue monitoring the area <br /> for changes. <br /> o Deltas were identified in ponds Deal and Middle Flume. <br /> o Sediment markers were not visible in ponds visited. <br /> o Secondary containment issues identified, see below in support facilities section. <br /> o Impoundment H has Elaeagnus angustifolia growing on the north and south banks. <br /> Number of Partial Inspection this Fiscal Year: 8 <br /> Number of Complete Inspections this Fiscal Year: 4 <br />
