SCOPE OF WORK FOR 1995 CLIMAX MINE RECLAMATION <br /> Task 1. Capping, Grading,Drainage and Erosion Control at Storke Yard and <br /> Storke Waste Water Pump Station (SWWPS) <br /> This task includes: <br /> (1) Grading the existing Storke Yard benches visible from Hwy 91 such that their impact is <br /> "softened" from straight, angular lines to an undulating and broken appearance. Grading can best <br /> be achieved with a track-mounted backhoe operating on the benches, pulling material back to fill in <br /> behind the machine. Some of the cribbing will be saved to maintain slope stability. <br /> (2) Regrading of the reclaimed Storke Yard to establish surface drainage features (swales, contour <br /> ditches, diversions) so that stormwater flow is directed away from the Arkansas River corridor and <br /> toward the Storke Waste Water Pump Station. <br /> (3) Grading the No. 5 Shaft manway area to affect drainage conveyance to the Storke Waste Water <br /> Pump Station to protect against a spill in the No. 5 Shaft Pump Facility. <br /> (4) Extension of the SWWPS flume using a rip-rap berm or vegetated channel to capture <br /> stormwater runoff and convey it to the SWWPS. <br /> (5) Provide fill on SWWPS roadway to extend level of road base to top of flume plus grading of <br /> roadway so that drainage enters the concrete-lined channel. <br /> (6) Channelize or consolidate seep drainage from toe of Storke Crusher parking lot fill by use of a <br /> slotted pipe wrapped in filter fabric and covered with clean fill. <br /> (7) Berm around SWWPS for spill control and stormwater control. <br /> (8) Removal of waste material in wedge below SWWPS next to Hwy 91. <br /> (9) Divert water from hill upgradient(south)of SWWPS and put silt fence along Arkansas River. <br /> (10) Grade the outslope of old Storke Dry parking lot by pulling back with track mounted backhoe. <br /> (11) All graded areas traversible with conventional equipment will be limed with agricultural <br /> limestone at a rate of 15 tons/acre (lime spec: minimum 90% CaCO3,>50%minus 60 mesh). <br /> (12) Following the lime application, all areas will be disked to incorporate the lime. <br />
