February 27, 2014 C- 1981 - 018 /Deserado Mine ZTT <br />The primary discharge is a riser pipe with the inlet was clear of any debris. BME recently cleared surrounding <br />cattails from the primary inlet area. The pond was discharging during the time of the inspection. The emergency <br />spill way was well armored with rip rap and a concrete cutoff wall. The main channel from the intermediate <br />facility bench was stabilized with rip rap. No cutting or instability was observed. The secondary channel from the <br />same facility bench needs to be reestablished. Sediment buildup has cause water to begin to form new paths away <br />from the secondary channel. All water is still captured and retained within pond DP -1. The beginning of the <br />secondary ditch is constructed with a rock check dam as additional sediment control prior to entering Pond DP -1. <br />Ponds PP -1 and PP -2 collect partial runoff from the facility area. PP -1 is an in situ pond located just below the <br />refuse bin and truck loadout. Pond PP -2 is semi -in situ with its main embankment stable and vegetated. The <br />spillway is a combination primary /emergency riser pipe spillway. Both ponds held water, were stable and no <br />issues were observed. <br />B -Seam Dewatering Pond pump was operating during the time of the inspection. The B -Seam Dewatering Pond <br />consists of series of 6 primary ponds that leads into an artificial wetland before reaching a final pond called the <br />Last Chance Pond. At the time of the inspection, water was present through the 6th cell and up to part of the <br />artificial wetlands section. Water had not reached the Last Chance Pond and stayed within the wetlands section. <br />The Last Chance Pond held minimal water from snow melt. To the date of this inspection, no water has been <br />discharged from the Last Chance Pond. <br />Ponds SS -1 and SS -2 collect runoff from the Slot Storage. Both ponds' primary spillways are trickle tubes. <br />Spillway inlets were clear of debris with stable and vegetated embankments. SS -1 was dry at the time of the <br />inspection. SS -2 held little water with no discharge. <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 />held water in each of the cells but with no discharge. RP -4 held minimal water at the time of the inspection with <br />no discharge. Primary discharge is a riser pipe with a rip rap armored channel as its emergency spillway. Both <br />spillways were clear. No issues with the embankments were noted. Pond RP -5 held water with no discharge. RP -5 <br />has a combination primary /emergency spillway and was armored with rip rap. Embankments were stable and <br />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 />Number of Partial Inspection this Fiscal Year: 5 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 3 of 8 <br />
