January 23, 2013 C-1981-014/Southfield Mine JHB final regraded bottom of reclaimed Pond 5 is between 6075 ft.and 6080 ft. Based upon the contours approved on Map 28,the eastern slope of Pond 5 would not be graded to assure retention of the GEC roadway. Final disposition of Pond 5 upon approval to remove the pond,would need to assure that this pond no longer functions as an impoundment. ROADS—Rule 4.03 Drainage 4.03.1(4)/4.03.2(4) Surfacing and Maintenance 4.03.1(5)and(6)/4.03.2(5)&(6) The Monarch Fan access road was inspected. Energy Fuels has implemented appropriate repairs to the rilling on the northern portion of the Monarch Fan Access road. The rill near Energy Fuels disturbance area boundary has been filled in, graded and additional large rock placed in the outfall to the east. Energy Fuels has established a water bar upslope from this repair. The water bar will direct runoff off the roadway. Energy Fuels also graded the rilling further south on the roadway just north of the intersection of a non-mining roadway that heads to the south west. This road appears to contribute additional runoff onto the Monarch fan road. Mr. Patterson said that this non-mining road provides access to a pasture and a landowner's cabin. Energy Fuels has established a water bar below(north)of the intersection to direct runoff to the drainage east of the roadway. Mr. Patterson inquired about adding water bars on the non-mining related road. Energy Fuels would need to keep improvements within the approved disturbance area. Any improvements not currently permitted would need to be submitted as a revision. Confirmation with the landowner regarding the proposed improvements is advised. Water bars up gradient from the intersection may effectively isolate the runoff from the non-mining related road and minimize the volume of runoff and sediment draining off the Monarch fan road. RECLAMATION SUCCESS-Rule 4.15,Rule 3: The inspection moved from MW-NW to the reclaimed portal area. Several areas that had previously been identified in DRMS inspection reports that need maintenance were observed and discussed. The slope located NW of the remaining topsoil pile and gravel pad at the reclaimed portal area has undergone some rill formation. Repair to these rills and establishment of vegetation on this slope is needed. We discussed correction measures to be taken within the permissions of Rule 4.15.7(5)(a). There is a small remaining topsoil stockpile located at the base of this slope. Mr. Patterson inquired if this topsoil could be utilized for the purpose of rill repair. The Division thought for the limited extent of repairs needed,this may be an option. Dan suggested Energy Fuels confirm with the landowner that the operator plans to conduct these repairs and utilize a portion of this topsoil stockpile. Mr. Patterson was in agreement with this idea. Mr. Patterson also inquired if excelsior blankets would be an appropriate mitigation method. The Division confirmed that we have seen success with erosion control blanket properly anchored on slopes to stabilize the soil and allow vegetation to become established. Use of a limited area of erosion control blanket would be permitted under Rule 4.15.7(5)(a). We also discussed mitigation of the slope immediately NW of the county road at this same location. Runoff from outside of Energy Fuels disturbance area boundary is running onto Energy Fuels disturbed area and adding sediment to the roadside ditch. This sediment reports to Pond 5,but rilling is starting on the sides of the ditch from this run-on. Mr. Patterson discussed armoring the ditch at the location that an undisturbed drainage meets the road ditch. Energy Fuels has durable rip rap on site. This mitigation would help slow the flow in the ditch. Establishment of vegetation on the ditch slopes would minimize the sediment as well.
