Riprap downdrains at the RDA were found in good condition. Some coal fines have blown <br /> onto the outslope of the upper most reclaimed bench. The operator may want to consider <br /> some form of wind break to prevent future issues from accumulating coal fines on the <br /> reclamation, should the pile surface remain uncovered and unreclaimed for an indefinite <br /> period. <br /> Support Facilities <br /> Work continues on portal and fan openings in preparation to breach the seals on the <br /> underground workings. A crew was observed working at the East Portal fan and work was <br /> noted at the West Portal and fan area on May 19. Debris and soil near the portal openings <br /> was being removed to measure and construct security grates at the portals. The West Portal <br /> fan housing was also being constructed and will be placed over the shaft once approval is <br /> granted by MSHA to remove the shaft cap. <br /> AU-EN MINE <br /> II <br /> Revegetation <br /> Reclaimed areas are progressing normal for this time of year. Houndstongue was noted at <br /> both the West Portal and along the 100-year ditch at the RDA. These weeds and other <br /> noxious weeds should be treated immediately to avoid flowering, seeding, and spreading. <br /> Overall, the site appeared normal for the spring season and in compliance with the approved <br /> permit and the Rules. <br /> 5 <br />
