ROADS -continued <br />the former highwall (a parcel excluded from the bond release request). The route would follow the <br />ranch road on the south side of the excess spoils pile to monitoring well HG-2. At the well, the route <br />would turn southwestward and climb the ridge to the slump. The permittee's representatives <br />explained that it would be necessary to install a culvert across a small drainage near well HG-2 where <br />the route turns from southeast to southwest. Possible impacts from the traffic were discussed, <br />including impacts to softer parts of the ranch road, the vegetation at the culvert, and ruts that could <br />form in the trail on the ridge following rain. The potential impacts appeared minimal and the <br />permittee's representative agreed to submit a minor revision. The culvert was installed later in the day <br />and trucks began hauling rock to the slump. <br />HYDROLOGIC BALANCE <br />Ditches <br />The contour ditches and the ditch that surrounds the excess spoil pile were in good condition and <br />appeared to meet design standards. The only water found in ditches in the permit area was a trickle <br />of flow in the ditch at the westernmost point of the excess spoil pile; this ditch carries water from seep <br />RSP-3. This ditch could use additional riprap where the ditch is Bullied at the inlet to pond HG-B. <br />The large collection ditch north of monitoring well HG-2 (at the southeast corner of the excess spoils <br />pile) has more vegetation (mainly yellow sweet clover) growing in it than last year when thistle was the <br />only vegetation in places. <br />The ditches in the mine area that are riprapped with "red dog" were in good condition. <br />Culverts <br />All five culverts in the permit area were clear, were in good condition, and did not show erosion at their <br />outlets. <br />Sedimentation Ponds <br />Estimated discharges were 75 gpm from pond HG-8 and 20 gpm from pond 003. Both discharges <br />were clear water. Both ponds' inslopes, embankments, and embankment outslopes are well- <br />vegetated, appear stable, and are not Bullied. Hose remains in place for spray irrigating shrubs in the <br />fenced enclosures that surround the ponds. The ponds are permanent. Discussion during the <br />inspection clarified that the entire land area contained within the two fenced enclosures where shrubs <br />are planted around the ponds are excluded from the current bond release application, but the pond <br />structures, themselves, are included in the release application. The fencing may be removed upon <br />bond release of the shrub parcels. <br />Monitoring Wells <br />No problems were found with the three monitoring wells. <br />Springs and Seeps <br />Seepage was active at RSP-1, RSP-2, RSP-3, and RSP-4. <br />Field Parameters <br />The following table lists field parameters measured during the inspection. The measured values are <br />consistent with the permittee's values from the same locations in the past year. In-lieu of the Division <br />collecting samples for analysis during the inspection, the permittee's consultants will submit to the <br />Division the results of lab analyses of samples that the consultants recently collected. <br />-4- <br />
