Vegetation is good in previously reclaimed areas. <br />Marker signs are o.k. <br />Lower Refuse Area Topsoil Pile <br />No soil material was placed in or removed from this pile during <br />the 1st quarter. Pile was seeded and mulched last summer, <br />vegetation is good. No erosion or slope instability was <br />evident. Drainage was in good condition. Marker signs were <br />o.k. <br />Lower Refuse Area Subsoil Pile - Sylvester Gulch <br />No subsoil material was placed in or removed from this pile <br />during the 1st quarter. No erosion or slope instability was <br />evident. Drainage was in good condition. Vegetation is good. <br />Marker signs were o.k. <br />Sylvester Gulch Road Relocation <br />The road outslope is in good condition. There is no evidence of <br />instability of the fill. Some very minor settling is visible in <br />an area of natural ground immediately south of the fill. This <br />area is being watched closely and is currently stable and not <br />causing any problems. Rip rap is in place and in good <br />condition. No problems are anticipated from spring runoff. <br />Lower Refuse Area Subsoil Pile - Near MB-6 <br />No material was placed in or removed from this pile during the <br />1st quarter. No erosion or slope instability was evident. <br />Drainage is in good condition. The pile was seeded in November, <br />1986. Material from the Sylvester Gulch road landslides may be <br />placed in this pile if necessary. <br />Lower Refuse Pile <br />Refuse was placed and compacted in the Phase I area of the pile <br />during the 4th quarter as specified in the approved plan. Minor <br />quantities of refuse was generated during the 1st quarter due to <br />the much reduced production rate. it is estimated that about <br />5000 tons of refuse was placed in the 1st quarter. Refuse was <br />placed in 24 inch or less lifts and compacted with a caterpillar <br />815 self propelled sheepsfoot compactor. Due to the small <br />quantities no compaction tests were done during the quarter. <br />The material placed during the quarter visually appears to be <br />well compacted and should meet the specified 908 maximum dry <br />density. The area will be tested in the following quarters. No <br />erosion problems were observed. Slopes were regraded and <br />dressed and appear to be in good condition. No slope stability <br />problems were observed. No evidence of spontaneous combustion <br />was observed during the quarter. The area on the North side of <br />the pile which was covered with 18 to 24 inches of subsoil and <br />seeded at various times during 1986 appears to be doing well. <br />Drainage is in good condition. Signs and Markers are o.k. <br />Sometime during the 2nd quarter placement of refuse will move to <br />the Phase III area. <br />
