January 28, 2013 C-1981-012/New Elk Mine LDS
• The "substation" SAE showed no recent disturbance.
• Ditches and culverts were in good order,unless otherwise noted.
• The system of three culverts that make up the clean water culvert C2 remained as they were during the
January 2, 2013 inspection,with a trench bypassing the downstream section(see photo 1). Either the
appropriate sections should be removed,leaving the centre section in place; or the trench should be
filled in and the upstream and downstream culverts should be cleaned out.In either case the permit
should be updated to reflect the physical reality on the ground.
• The outlet to clean water culvert C3 was partially blocked. The culvert should be cleared out.
• Machinery and equipment was encroaching into ditch D5 (see photo 2). This equipment should be
moved.
• The slurry injection SAE showed no recent disturbance.
• Pond 4 was dry. The embankment was sound and both the primary and emergency spillways were in good
order.
• The ditches and culverts around DWDA 1 were clear and functional.
• Water flowing through the clean water ditch which conveys water from the highway culvert west of the
main gate to the Purgatoire River had eroded the gabions near the river(see photo 3). The gabions should
be replaced or restored to ensure that excessive erosion does not occur.
• There was no evidence of recent disturbance at the lower of the two water tank pads; however uphill at the
larger pad the low spots in the berm noted previously had not been built up (see photo 4). The berm
around the SAE should be built up where it is low.
On the north side of the highway:
• The upland diversion ditch above the RDA was clear and in good order. There was no evidence of
breaching. At the time of the inspection a survey of the regraded ditch was in progress.
• There was no sign of recent disturbance at the cell phone tower pad, or the lower pad located immediately
to the north.
• The damaged section of the culvert under the conveyor, C41,had been replaced and the area around it
filled and restored.
• All culverts under the haul road up the west side of the RDA were clear.
• The embankments and spillways of pond 8 were sound.
Between the highway and the Purgatoire River:
• The temporary conveyor that had previously constricted access in this area had been removed.Work was
underway to remove culverts C70 and C71 (see photo 5). This project should be completed as soon as
possible,with the relevant changes made to maps and tables in the response to the mid-term review.
• Work was underway to re-route the flow from the first highway culvert (roughly north of the eastern end
of DWDA 2),and second highway culvert(east of the small gate),to culvert 00. The culvert will be
replaced with a 48"diameter culvert. The same project had led to the removal of culverts C14 and C14A,
with the intention of diverting flow to ditch D19. This project should be completed as soon as possible,
with the relevant changes made to maps and tables in the response to the mid-term review.
