Affected area <br /> perimeter markers were observed. Water treatment facility was operating. Operator stated that <br /> approximately 500 gpm discharge from American Tunnel is augmented with diverted flow from <br /> Cement Creek, total 1600 gpm, treated. Discharge from American Tunnel occurs in front of the <br /> sealed bulkhead. Discharge from the water treatment facility to Cement Creek is monitored per the <br /> requirements of CDPS Permit No. CO-0027529. All mine drainage and drainage from yard and <br /> facilities area reports to treatment facility. Upland diversion, around the Sunnyside dump, was well <br /> maintained, discharge was visually estimated at 20 gpm. Riprap lining along Cement Creek <br /> appeared stable. <br /> Lead Carbonate Tailings Pond MRP - Reclamation of the pre-law tailings, located on the south bank <br /> of South Fork Cement Creek appeared to have been completed in accordance with the Act and <br /> Rules and Regulations. Operator stated that approximately 70,000 tons of pre-law tailings had <br /> been relocated to Mayflower Pond 4 and stabilized with high pH material. Affected area was <br /> backfilled and graded to blend with surrounding topography. Vegetative cover was dense and <br /> diverse. Various grasses, clover, willow bushes, spruce and pine trees were well established. <br /> Approximately 60% of the transplanted spruce were thriving. No evidence of excessive erosion, <br /> slumping, settling or instability was observed. <br /> Operator stated that natural pre-mining conditions of the area may have been an iron bog. Operator <br /> stated that evidence of natural iron bog were located during tailings removal and are evident in <br /> water quality of an existing pond, located up-gradient of reclaimed area.

Several seeps/springs were evident <br /> along the base of the graded slope. Evidence of slope instability was not observed. Drainage <br /> channels had been constructed within the graded areas. Riprap linings appeared stable at outlet <br /> of drainage channels. Straw bale sediment filters were intact. Vegetative cover consisted of <br /> various grasses and transplanted willow bushes. Vegetative cover was well established for <br /> approximately 60% of the reclaimed area. <br /> Cement Creek Diversion - Inlet, outlet, clean-out and overflow structures were well maintained. <br /> Snow shed with heaters and lights had been constructed over diversion culvert inlet. Operator <br /> stated that snow shed and heaters were necessary to maintain inlet structure during winter season. <br /> Minor slope movement was evident along the cut slope for the buried diversion culvert. <br /> Material Borrow Source - Reclamation of material borrow area appeared to have been completed <br /> in accordance with the reclamation plan and in accordance with the Act and Rules and Regulations. <br /> Overall slopes were visually estimated at 3H:1 V, slopes appeared stable and well vegetated. <br />
