diversity based on reference areas as well as a woody stem density of 1000
stems per acre. This block may be sub-divided into two or more parcels, at
PSM's discretion, to reduce variability among the various revegetation
efforts applied to this block (i.e., live-handled, roto-cleared, non-
seeded, topsoiled areas; live-handled, roto-cleared, seeded, topsoiled
areas; stockpiled, roto-cleared, seeded, topsoiled areas, etc.). Interim
sampling for this block will include cover, diversity and woody stem
density.
The Facilities reclamation block area also falls under Rule 9.15.10
and consists of previously disturbed areas which includes: the upper and
lower office areas; and all ancillary facility areas such as reclaimed
roadways, ponds, or other areas where only minor disturbance occurred. The
revegetation success standard for this block consists of only a cover
standard (478). This block (Exhibit 9.9-2) may be sub-divided to two or
more parcels, at P6M's discretion, to reduce variability caused by location
(i.e., Trout Creek drainage vs. Oak Creek drainage, non-topsoiled vs.
opportunistic topsoiling efforts, etc.). Interim sampling for this block
will include only cover.
• As previously stated, all of the reclamation blocks at the mine
received significant manipulation during 1996. Therefore, interim
revegetation monitoring will be required during Years 3 (1999) and 9 (2000)
of the extended liability period. This will allow adequate time for
evaluation of monitoring data, plan formulation, CDMG approval and mine
implementation of any required corrective practices prior to the end of
Revegetation Year 5 (2001). In the event that monitoring in Year 3
indicates a severe deficiency in some parameter (i.e., diversity, woody
stem density, etc.), corrective measures may be performed in Year 4 rather
than delaying until Year 5. In this instance, upon CDMG approval,
corrective measures will be employed in Year 9 and monitoring relating to
that aspect of the interim monitoring program may not be performed during
Year 4.
A total of twenty ten-point frame transects will be taken during both
Years 3 and 9 in each of the bond release blocks. Since the reclamation
blocks that may exhibit significantly different rates of revegetation
establishment and growth, the twenty sampling points may be distributed
evenly between anticipated parcel sub-division. In this instance, the data
obtained may be evaluated separately for each parcel. This will ensure
• that any corrective measures implemented will address the actual parcel
area deficiencies identified through the monitoring process. A report will
