Manual of the mining permit. <br /> Ground Water Impacts <br /> One bedrock well (83-02), exists down the hill and to the north of the Utah Tract,monitoring water <br /> levels in the mine relative to subsided areas. Wells 83-02 and TR-7a monitor the Middle Sandstone <br /> formation. A second bedrock ground water well TR-7a, exists to the west and south of the Strip Pit. <br /> Well TR-7a is within the expected flow path of mine leachate. Well TR-7a data indicates the <br /> parameters monitored are within their baseline water quality levels. The pH levels at this well <br /> fluctuated above and below the drinking water standard but within the baseline levels. Water levels <br /> are trending upwards. The upward trend may be attributed to the cessation of mining and dewatering <br /> activities. There are no water quality monitoring wells in the bond release blocks. <br /> Surface Water Impacts <br /> The four permitted ponds located in the Strip Pit Area rarely hold water. Sediment ponds at the site <br /> generally only hold a small amount of water for a short period of time between March and June. <br /> Permanent pond PA-PI is the only pond to have a record of discharge, and has not discharged since <br /> 1990. Structures have been designed as per the permit to contain the requisite flood events. Division <br /> reviews indicate that there have been no water quality problems at these ponds. A spoil spring,No 1 <br /> Strip Pit, outfall 022,is monitored for NPDES parameters. The spring generally discharges as a result of <br /> snowmelt form March through June. Total dissolved solids, and iron concentrations have trended <br /> upwards since 2002 with levels remaining within historic ranges. Surface sampling site Y-2 is located to <br /> the west of the Strip Pit. This site has a quarterly sampling requirement of water quality parameters. No <br /> significant,unpredicted or adverse environmental impacts to water quality have been noted based on <br /> review of the 2019 AHR. <br /> Utah Tract <br /> Cover and Species Composition <br /> The reclamation standard for cover in both 2014 and 2015 have been met in the Utah Tract for Range <br /> Sites A and B as discussed above. <br /> Production <br /> The sample mean was greater than 90%of the reclamation standard but, sample adequacy was not achieved <br /> in either Range Sites A, B or Reference Area 3 in 2014 or 2015. Therefore, a t-test of the reverse null <br /> hypothesis, described in Rule 4.15.11(2)(c), was used to demonstrate reclamation success for both range <br /> sites in 2014 and 2015. <br /> The reverse null hypothesis was rejected and for Range Site A in 2014 and 2015. Allowable production <br /> in 2014 for the area was 1459.7 lbs/acre, in 2015 allowable production was 11010.0 lbs/acre, again <br /> exceeding 90% standard of 500.9 lbs/acre. <br /> Permit Number C1981044 Page 22 of 25 <br />
