C-88-023 was issued on May 4, 1988 and terminated on August 18, 1988. This
violation was issued for failure to maintain cover material in a stable
configuration. Two steps were required to abate the violation: first, the
operator was required to install drains to eliminate excess moisture from the
slump site; second, they were required to repair and regrade the slump to
blend with surrounding cover material. A ten-day notice was issued regarding
this slump on March 28 following a March 7 inspection.

noted in the inspection report for that date.
OSM Oversight: Inspection performed on March 7.
O. Problems - A small surficial slump in the top four feet of cover
materia^f was first noted during the March 11 inspection. The slump was
measured on that date and diagrammed during the August 18 inspection
conducted by Jim Pendleton, Seepage and salt collection present just
below the slump was noted throughout the spring and summer. Both
problems were addressed successfully with the installation of three
cloth-wrapped, 5" vented PVC drains underneath the slump. These drains
and regrading of slumped material allowed the violation written in
response to these problems to be terminated.
Other Concerns:
1. Pond #5 was discharging during the March 11 inspection.
2, Weeds may eventually become a problem at this site, especially on the
top of the bench and below the riparian zone. Weed comments are included
in the November 3 inspection.
