The operator eliminated and reclaimed the LU -2 road this past summer; <br />grading, topsoil replacement, and seeding have all been completed. Grasses were germinating in the reclaimed <br />cor ridor. <br /> <br />The pumphouse slide repair was complete. Two toe drains have been installed; both were dry at the time of the <br />inspection. It is possible that the base of the slide above the rock drains may have been oversteepened; the <br />operator should monitor the se areas and grade as necessary if sloughing occurs. <br /> <br />The oil well slide repair has also been finished. The entire slide was regraded, and a rock buttress was placed at <br />the base on the east end of the slide. Water was flowing from the newly constructed t oe drain. This repair also <br />may be too steep and may require further grading and possible westward extension of the rock buttress. The <br />operator indicated that this area was left fairly steep in an effort to minimize disturbance of the reclamation <br />upgradie nt of the slide. Further monitoring is warranted and repairs and/or additional buttressing should be made <br />as necessary. <br /> <br />The repaired MEHR slide area remained stable. Repairs to this slide were complete in June and included <br />lessening of the road embankme nt (coincident with road corridor reclamation) and installation of a toe drain. <br /> <br />ENFORCEMENT ACTIONS/COMPLIANCE <br /> <br />No enforcement actions were initiated as a result of this inspection, nor are any pending.
