panels to minimize impacts to West Fork Terror Creek. Primarily, <br />this will consist of orienting panels approximately parallel with the <br />creek as currently proposed and represented in the Subsidence <br />Report (WWE, 2013a), thus reducing the number and severity of <br />transitions from subsidence to non -subsidence zones. <br />The lessee/operator would design and implement a stream flow <br />measurement program. The program will consist of establishing <br />monitoring stations upstream and downstream of the expected <br />subsidence area on West Fork Terror Creek. Flow monitoring <br />stations will be designed and calibrated by water resource <br />engineers and will focus on continuous measurements of low and <br />base flow conditions (i.e., summer through late fall). <br />Lessee/operator staff will have trained staff available to conduct <br />site visits to ensure continuous flow measurements are recorded <br />on a minimum monthly schedule, weather permitting. Flow data will <br />be compiled into an annual report that will include comparisons to <br />previously collected data. This report will be submitted to the BLM, <br />USFS and USFWS. <br />The lessee/operator will conduct fish, sediment and <br />macro invertebrate sampling (as performed by WWE and MEC in <br />2012) every two years during and twice following the mining <br />activities (at 5 and 10 years periods) prior to bond release. A report <br />should be distributed to the BLM, USFS and USFWS documenting <br />if statistically significant declines are observed related to mining <br />activities. If a statistically significant decline in the fishery within the <br />subsidence area results from the Proposed Action (i.e., a decline <br />at sites within the subsidence area does not correlate with a <br />decline in the fishery outside the subsidence area), the <br />lessee/operator will investigate the cause of the decline. If the <br />decline is resulting from habitat changes as a result of longwall <br />mining induced subsidence, the operator/lessee will engage a fish <br />habitat ecologist to design habitat enhancement structures to <br />mitigate the observed impacts. If a decline in fish numbers persists <br />following mitigation of an observed physical or chemical impact, the <br />lessee/operator will work with CPW to capture and grow out fish <br />populations from appropriate breeding stock. The lessee/operator <br />will establish a minimum of two subsidence monitoring gridlines <br />PR -14 2.05-104 03/14 <br />
