previously reclaimed. <br />Bond for Remaining Reclamation Work <br />The estimated cost for a third party to complete the remaining approved reclamation work, including <br />any revegetation that may be required, is $40,526 SZ. Approval of the proposed decision on this <br />application, a reduction of $175,121 from the current required bond of $270,733, leaves a minimum <br />bond requirement of $95,612. Remaining approved reclamation work consists of: <br />1 Task 008, seal piezometers D 1-A and D 2-A <br />2. Task I lb, reseed the entire reclaimed area in the event of vegetation failure <br />3. Task 012, mobilize/demobilize equipment <br />4. Task 15b, demolish a bridge and four flume bases <br />5 Task 16, clean the permanent ponds of sediment <br />6. Task 17, haul pond cleanings to an approved disposal area. <br />Degree of Difficulty to Complete any Remaining Reclamation <br />Remaining reclamation of the areas for which Partial Phase I and Partial Phase II is proposed is <br />limited to monitoring and correction of any deficiencies that may develop. There are no known <br />deficiencies, and correction of those that might develop (such as loss of vegetation s3 or development <br />of erosional features) do not present a great degree of difficulty. The two flume bases in North <br />Thompson Creek, the two flume bases in Middle Thompson Creek, and a bridge spanning North <br />Thompson Creek for the Stoney Ridge fan shaft road are currently required to be removed. There is <br />no Phase I or Phase II bond release proposed for the flume bases $4 and bridge 55 reclamation in this <br />bond release action. There is some degree of difficulty in the removal of these structures. Only <br />unimproved dirt roads reach the vicinities of these features, and hand labor may be required to <br />minimize adverse impacts to ripazian habitat. Bond requirements aze retained in this proposed <br />decision to accomplish this demolition work. Other remaining reclamation work consists of <br />reclamation of we]]s D 1-A and D 2-A s6 and cleaning the sedimentation ponds 57. There is little <br />difficulty in accomplishing these last two tasks. <br />Occurrence of Surface or Groundwater Pollution <br />No occurrence of surface water pollution from precipitation runoff has been identified.
