CHRONOLOGICAL HISTORY OF REVEGETATION & BOND RELEASE
As of 2015, all disturbed areas not deemed permanent have
been seeded. Total areas seeded and revegetated prior to 2015
are shown on 2012 annual reclamation report Chronological
Seeding Map. SCC submitted SL -5 requesting Phase II bond
release on eligible areas, which was approved on approximately
798 acres (as shown in Figure 2).
The Report of Findings for Revegetation Success for Phase II
Bond Release will be submitted separately.
SEDIMENTATION POND SURVEYS
SCC is required to monitor sedimentation ponds for sediment
storage capacities. This monitoring is conducted by physically
surveying each pond each year. This schedule provides a
sediment yield history and gives advanced warning to
operations personnel when sediment clean-out work is needed.
Also, in accordance with Rule 4.05.6(11)(c), SCC visually
inspects each pond, at a minimum, quarterly each year. During
these inspections, any significant observed change in sediment
storageor noticeable expansion of the sediment delta at the
inlet to the pond are noted as conditions requiring pond
maintenance.
The results of the 2015 annual survey indicated that all ponds
are above the minimum requirement for storage as summarized
by Table 13.3, Sediment Pond Capacities.
