September 26,2013 C-1981-018/Deserado Mine ZTT <br /> time of the inspection. <br /> Ponds RR-1 and RRS-1 are located south of the railroad loop. Both ponds collect runoff and wash down water <br /> from the train loadout. Both ponds were stable.Both ponds were dry at the time of the inspection. <br /> All refuse pile ponds were inspected. RP-1 collects runoff from the reclaimed Refuse Pile 1. RP-1 was dry and <br /> well vegetated. The riser pipe primary spillway inlet and outlet were clear of any debris. Embankments were well <br /> vegetated and no signs of instability. Pond RP-2/3 consists of three cells. Runoff from Refuse Pile 2/3/4 are <br /> directed into two upper cells. Once water fills to the spill way of these two upper cells,water then enters the larger <br /> third cell. The primary discharge is a riser pipe. The emergency spillway was armored with rip rap.Pond RP-2/3 <br /> was dry.RP4 held minimal water at the time of the inspection with no discharge.Primary discharge is a riser pipe <br /> with a rip rap armored channel as its emergency spillway. Both spillways were clear.No issues with the <br /> embankments were noted.Pond RP-5 was dry. RP-5 has a combination primary/emergency spillway and was <br /> armored with rip rap. Embankments were stable and vegetated. <br /> Small Area Exemption's (SAE)within Deserado's permit are constructed with either a combination of berms and <br /> rock check dam,gravel pads or cross ripped grading for erosion control. The following SAE's were inspected: <br /> • Nitrogen Injection and Degas Borehole Pads <br /> • Water Storage Tank <br /> • Explosives Storage <br /> • Haul Road Blisters <br /> • Radio Tower <br /> • Rock Dust Tanks <br /> No signs of erosion were observed in any of the SAES. As noted in the Backfill and Grading section of this report, <br /> the recently constructed pad for the future nitrogen borehole N11-58 is in need of sediment control structures. <br /> All culverts within the facility area except for one were clear of all sediment. The culvert that runs below the <br /> access road to the Moon Lake Substation was partially filled with sediment in the outlet.The sediment within the <br /> outlet would most likely flush out in the event of a precipitation event. <br /> Number of Partial Inspection this Fiscal Year: 2 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 4 of 8 <br />
