In addition, a cased hole exists at this site and was used to discharge water <br />from the mine into storage ponds on the surface. This area is accessed by its own dedicated road. <br />The road into this site is in poor condition. A powerline passes through this site, but the <br />transformers have been removed. The powerline is the property of the Operator. The site is <br />quite well vegetated (comparable to existing undisturbed areas). <br />The primary access road over the ridge south of the Sunday Mine and though the area of <br />the vent holes is a preexisting road on BLM lands. This road, and the main branches off this <br />road into the area of the West Sunday vent holes, is bladed and maintained by San Miguel <br />County. The section of the road on the north-facing slope of the ridge is subject to erosion due to <br />the steepness of the terrain and the composition of the rock <br />and soil formations.

In <br />discussions with past employees of prior operators, no one can recall that any of these old vents <br />have been used since most probably in the 1960's. The vents all enter into areas of the mines <br />which are no longer accessible. These PreLaw sites are described as follows (east to west on <br />Figure 2). <br />- 20" Vent above southeast corner of Sunday site -The access into this site is getting <br />hard to discern from the native surroundings and vegetation. Although the road <br />shown on Figure 2 is eroded in places, it is not materially different from surrounding <br />terrain. Access to this site is by foot. The vent hole is a galvanized metal tube <br />covered with old vent bag. It is located beside an empty power pole and remnants of <br />an old wooden structure, which serve as landmarks to help locate this site. The vent <br />site is stable and very well revegetated. <br />2' Vent up the steep slope to the southeast of S-7 Vent -The access road to this site in <br />practically grown shut and can only be traversed by vehicle for about half of its <br />length; the upper half of this road is impassable and deeply eroded. The road passes <br />through a number of shale and clay horizons, and although the road has eroded, it is <br />not dissimilar from the erosion and cutting that is taking place on unaffected <br />exposures. The road is quite well naturally revegetated with sturdy native brush and <br />shrubs. Any attempts to re-utilize this road would cause considerable disturbance to <br />areas that have naturally reclaimed. The vent site is well vegetated. The vent hole <br />has a steel riser on the hole. The powerline into this site is the property of the <br />Operator. While certainly not constituting conclusive evidence of the timing of <br />historical use, a vehicle license plate from 1969 was found at this site. <br />3 <br />
