(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1977-129 <br />INSPECTION DATE 5-11-2004 <br />INSPECTOR'S INITIALS SSS <br />This was a routine monitoring inspection conducted as part of DMG's ongoing monitoring program for permitted mines in <br />Colorado. The inspection was also conducted jointlywith Bruce Fowler and Dave Trappet, U. S. BLM Grand Junction Office, <br />on the portion of the mine site where the surface was purchased by the Bureau of Reclamation and is now being administered <br />by the BLM. The BLM administered portion of this site is in final reclamation and BLM personnel requested this inspection to <br />ascertain what additional reclamation requirements DMG might have for that parcel. <br />The mine identification sign and affected area boundary markers are in place and in compliance with Rule 3.1.12. <br />No significant erosional features were noted on the affected areas of the site. The facilities area appears more or less the <br />same as it did during the 1999 inspection. These facilities are maintained clean and free of clutter. <br />Topsoil and overburden stripping and dewatering trench excavation has begun in Stage 2 -Part B. During permitting, it was <br />noted that a well permit would be in place for this stage, prior to exposing groundwater. The lower Gunnison River drainage <br />was designated as "over-appropriated" in late January 2004. In addition to a well permit, all excavations within 100 feet of the <br />lower Gunnison River, and all new excavations in the lower Gunnison River drainage that expose groundwater must now <br />secure a water augmentation plan for the consumptive use of that water. WBM is encouraged to verify, with the State <br />Engineer's Office, that adequate water rights are in place for all their applicable current and future excavations that expose <br />groundwater. <br />Backfilling of the highwalls in Stage 2 - Part A continues on the east end of the north highwall. Overburden is being hauled <br />from the terrace Stages (Stage E) to the backfill location in Stage 2 -Part A. A small Portion of Stage E and all of Stage F are <br />all that remains to be excavated in the Terrace area. Most of the previous terrace stages have been backfilled and graded, but <br />vegetation establishment on these Stages was not inspected during this inspection. The pit is nearly mined out with a portion of <br />the southeast corner and some material across the pit floor remaining. Some stockpiled material also remains on the central <br />floor of the pit. To transport the Stage 2 - Part B gravel to the processing facilities, W BM will keep Stage 2 - Part A dewatered <br />and transport through that pit. This is not a recommended practice, as it delays reclamation, leaves a large area exposed for <br />numerous years that will require costly weed control, and may contribute to dust problems. <br />The BLM administered portion of the site encompasses primarily Stage X, Stage Y and Stage 1. This portion of the site was <br />originally owned by an adjacent ranch owner who used the area for cattle feeding. That parcel was sold to the federal <br />government in 2001 with their intent to breach the Stage 1 pond to create habitat for endangered fish species along the lower <br />Gunnison River. The pond breach project has been completed with two armored channels having been constructed between <br />the Stage 1 pond and the Gunnison River. The upstream channel was placed where a slump had previously occurred on the <br />east side of the pond embankment, subsequently removing the need for the operator to repair this slump feature. The base of <br />channel was approximately 1 foot above the river level during this inspection. The lower channel was constructed on the north <br />side of the pond embankment and was just starting to allow water to pass through it. The channel features are not an approved <br />feature of this permit. However, the operator is aware that the permit must be revised to include them. These unpermitted <br />channel features are noted as a problem on page 5 of this report, with corrective actions and a correction date specified. <br />The majority of the revegetation efforts on Stages X, Y and 1 have not been successful. W ith little exception, the vegetation on <br />the reclaimed areas that lie more than 4-5 feet above water level (in the Stage 1 pond) consist of annual species. A brief <br />inspection of adjacent non-mined lands indicates that the vegetation there also consists primarily of the same weedy species. <br />Cattle grazing certainly plays a part in the poor revegetation success and the poor state of the vegetation on the land adjacent <br />to the mine site. Stage X was seeded initially in November 1978 using 300 pounds of oats (to help spread the seed) and 200 <br />pounds of 20-15-5 fertilizer. Initial reports indicated good germination, but then drought conditions dried up the vegetation. In <br />1979 the permit was revised to allow Stages X, Y and 1 to sit fallow until the pond in Stage 1 was complete and refilled with <br />water. The regrading and topsoil replacement was completed and the pond was full in the spring of 1996. Some seedling <br />planting was completed in fall 1996 and spring 1997, including a wetland area in the southeast corner of the pond. This area <br />was monitored in fall 1997 and reported to have approximately 50 percent survival at that time. The applicable portions of <br />Stage Y (areas not designated for cattle feeding) and all but the east portion (slump area) of Stage 1 were initially seeded in the <br />fall of 1999. <br />
