January 28, 2013 C-1996-084/Lorencito Canyon Mine LDS
company operating in the area(XTO).
The weephole on the riser in pond 9b was very close to the level of accumulated sediment level in the pond(see
photo 6). The level of this hole should be checked against the specifications of the riser(which are defined in
exhibit 15 of the permit file). Three of the four culverts on the road to pond 9b are the responsibility of XTO. The
culvert at the bottom of the down-drain is the responsibility of NECC; it was clear.
Rock check dams above pond 6 had been cleaned out and straw bales had been restored (see photo 7). The gully to
the side of the emergency spillway of pond 6 had been repaired with rocks and protected by bales (see photo 8).
The pond embankment should be surveyed during the next quarterly pond inspection since it is not clear that the
emergency spillway is the lowest point on the embankment. An erosive gully exists above the pond but is
stabilized by rock armoring on lower section.
Ponds 7 and 9a,and the drainages that report to them, were in compliance.
GENERAL MINE PLAN COMPLANCE:
As noted in a previous inspection report, identification of the important features at the Lorencito Canyon site is a
difficult task, exacerbated by the lack of a complete map or maps. This problem is to be addressed during the
permit renewal process.
The map(s)must clearly identify all features,but in particular:
• Roads and culverts that NECC is responsible for,and those that are maintained by third parties.
• Ponds, as identified on the NPDES permit(what has been referred to as "pond 9"in the DRMS permit is
apparently"pond 9b"in the NPDES permit)
Until the permit renewal process is completed,map 1 from the 2008 Annual Reclamation Report will be used for
reference.
ROADS—Rule 4.03
Construction 4.03.1(3)/4.03.2(3),- Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance4.03.1(5)and
(6)/4.03.2(5) and(6); Reclamation 4.03.l(7)/4.03.2(7):
The roads around the mine site were all in good condition.
RECLAMATION SUCCESS -Rule 4.15, Rule 3:
Rills and gullies continue to need ongoing monitoring and repair around the site. Of particular note was a large
gully on a north facing slope in the area between pond 8 and pond 9b,near the top of the drainage. This gully was
several feet wide and deep,and should be repaired(see photo 9).
REVEGETATION—Rule 4.15
Vegetative Cover; Timing:
An accurate assessment of vegetative cover was made difficult by the snow,however Winterfat was observed on
the slopes of the 'nob'.
SIGNS AND MARKERS—Rule 4.02:
Mine ID signs were updated by the end of the inspection to show the current telephone number and address of
NECC.
