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 inspection <br />and the facts or evidence supporting the enforcement action. <br />This was a complete inspection of the Yoast Mine conducted by Mike Boulay of the Division of <br />Minerals and Geology (D1vIG). The inspection was completed over the course of two days. The <br />inspection occurred on the afternoon of March 22, 1999 and was completed on the morning of <br />March 23, 1999. Chuck McCulloh of Seneca Coal Company (SCC) was present on March 22, <br />1999 and Mike Altavilla of SCC was present during the inspection on March 23, 1999. No coal <br />was being hauled from the mine site during the inspection, and the dragline was operating in the <br />southeast end of the current pit. No precipitation occurred during the inspection. The ground <br />was partially snow covered, with some locations of the mine site wet from snowmelt and runoff. <br />Roads <br />Roads site wide were dry and in good condition. The road to Pond O11 was generally well <br />maintained and mostly dry. Ditches along the road to Pond 011 were mostly snow packed with <br />some Horning water. Haul Roads A and B were well maintained with ditches in good condition, <br />dry, and cleaz of debris. <br />Hydrologic Balance <br />The surface of Pond O11 was frozen and the level of water in the pond was well below the level <br />of the primary spillway. Pond O 10 was full at the time of the inspection and mostly clear of ice. <br />This pond was discharging. Both ponds appear to be functioning properly. <br />Site ditches and culverts were inspected to ensure proper drainage control throughout the mine <br />site. With the exception of one location as discussed below, mine site ditches were functioning <br />properly to provide sediment and drainage control. <br />Please continue to maintain site culverts along Haul Road A and Haul Road B. Culvert YB I on <br />the upgradient end of Ditch No. 2 is neazly completely full of sediment. Please clean the <br />sediment from the culvert and consider removing the excess sediment that has accumulated in the <br />ditch below the discharge end of the culvert. A gully is forming on the east side of Haul Road B, <br />south of Culvert YB 2. Please take appropriate measures to ensure that this location does not <br />continue to erode. <br />As the inspection proceeded to the current pit azea, it was noted that a significant amount of <br />runoff was present in the drainage ditch along the southwest side of the ramp. At one point along <br />the ramp, the water breached the ditch and flowed out of the ditch into a previously undisturbed <br />azea. Water flow estimated at approximately 50 gallons per minute flowed out of the ditch, <br />across a small section of spoil material and down a slope into the east side of Armand Draw. The <br />
