III. COMMENTS-COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made during the
inspection. Comments also describe any enforcement actions taken during the inspection and the facts or
evidence supporting the enforcement action.
Neck Pit and Vicinity
For the purposes of SL-2, this area includes the reclaimed Haul Road "D" corridor(discussed
previously in the "Roads" section of the report), and all disturbed lands located to the north of the
Section 18/19 and Section 17/20 boundary lines, with the exception of the North Pit area, which
is addressed separately in this report. The release request area includes reclaimed slopes and
reclaimed drainage channels along either side of permanent road LU3A, and additional reclaimed
areas south of the southern end of LU3A to the Section 17/20 boundary line. SCC excluded
certain locations within the general area from the release request, including the road travel
surfaces as previously described, an area east of LU3A and south of YPM-11 that had been used
for dragline disassembly and was only recently reclaimed, the substation location west of LU3,
and a narrow corridor for YPM-20, which had not yet been constructed at the time the SL-2
application was prepared.
The Division believes that certain additional areas should be excluded, and will describe and
delineate the additional proposed exclusions in the proposed decision for SL-2. These exclusions
include two topsoil stockpiles near the north end of the Neck Pit block, and a major portion of
the YPM-8 watershed in the southern portion of the block. Topsoil Stockpile "C" located north
of the substation site is fully intact, while a portion of Topsoil Stockpile"D", located near the
former explosives storage area west of the permanent road in the Pond 10 vicinity,has been only
partially used up. Conformance with AOC requirements with topsoil stockpiles in place is
questionable, and there is no certainty that additional soil from the stockpile locations will not be
needed for future reclamation or erosion repair.
Regarding the YPM-8 watershed, a portion of the watershed upstream (south) of the point where
YPM-8 crosses the temporary maintenance road 1300 feet north of the 17/20 section line, has
been substantially disturbed since the July SL-2 inspection by construction of an earthen dam
erosion control structure. The YPM-8 channel itself, downstream of the road crossing has been
substantially eroded the last two years following initial construction. SCC implemented
measures this year to prevent recurrence of erosion along the channel and downstream (including
the erosion control structure, increased width of the YPM-8 TRM lined channel, use of staked
willow wattles to slow and direct flow, and construction of an "ice jam overflow channel"
adjacent to the main channel. These measures are expected to be effective,but given the
recurrent erosion problems in the watershed, the Division believes it would be prudent to
withhold Phase 1 bond release until the effectiveness of the installations can be observed
following runoff season. The YPM-8 watershed exclusion area would be described as follows:
