III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the <br />inspection and the facts or evidence supporting the enforcement action. <br />This was a complete inspection of the Sanborn Creek Mine conducted <br />by Tony Waldron of DMG along with Tom Anderson of Pacific Basin <br />Resources. The mine is actively producing and shipping coal and is <br />permitted to produce 1.3 million tons per year. On August 31, 1995 <br />a Succession of Operator and Transfer of Permit was approved to <br />transfer this mine from Somerset Mining Company to Pacific Basin <br />Resources and change the name from the Somerset/Sanborn Creek Mine <br />to the Sanborn Creek Mine. <br />The inspection began by checking springs that have been identified <br />for monitoring in the Coal Gulch drainage. These springs were <br />originally identified by West Slope Carbon for their Hawk's Nest <br />Mine and when the current mining began in this area, the Sanborn <br />Creek Mine began monitoring these sites. The results of the field <br />monitoring is listed below. <br />Spring # 1- No flow and the area is dry; this area appears to be <br />more of a surface area depression where snowmelt and rain water <br />collects rather than a spring fed area. <br />Spring # 2- No flow and dry; this area may simply be an additional <br />monitoring point located in the same drainage as spring # 4 that is <br />really more of a surface monitoring point as opposed to a spring. <br />Spring # 3- No flow and dry; this may also be an area where surface <br />runoff causes flow in the spring and it simply dries up in the <br />fall, absent precipitation events. <br />Spring # 4- This location was expressing a small but constant flow <br />of good quality water and is typically what would be considered a <br />spring with hydrophytic vegetation surrounding the location <br />indicating that over time there is a steady supply of water. The <br />field readings were as follows: pH= 7.9; Ec= 254; T= 8 degrees <br />celsius; flow was i.2 GPM. <br />Spring # 5- This location was also expressing a very small but <br />constant flow of good quality water and would also be considered a <br />more typical spring. Field parameters were as follows: pH= 7.8; <br />Ec= 144; T= 12.7 degrees celsius; flow was less than 0.1 GPM <br />Both locations for springs 4 and 5 were located in small surface <br />water drainage bottoms that carry a significant amount of surface <br />flow during spring runoff. During the fall of the year the <br />drainage, both up and down gradient from these locations, was dry. <br />This fact coupled with the good water quality indicates that these <br />springs are probably surface alluvial in nature. <br />
