HYDROLOGIC BALANCE - Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7,
4.05.10; Effluent Limits 4.05.2; Surface Water Monitoring 4.05.13; Impoundments 4.05.6, 4.05.9
• Ponds 007 (Photo 2) and 011 were both discharging at a steady rate. No discharge was occurring
from Ponds 008, 0091 012 or 013.
GENERAL MINE PLAN COMPLANCE
• The San Miguel Generating Station was shut down for repairs to the plant's turbine. Due to the shut
down, there were no active mining operations occurring during the inspection. The mine's shovel
was parked on the backfilled area behind the pit, for maintenance and repairs (Photo 3).
OTHER(SPECIFY)
• We observed the concrete division box for the CCC West Lateral Ditch, located just outside the
western boundary of the permit area. Mr. Fry described the system of buried pipelines that carries
irrigation water from the box to various parcels within the permit area and beyond.
ROADS—Rule 4.03
Construction 4.03.1(3)/4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance 4.03.1(5)
and(6)/4.03.2(5) and(6); Reclamation 4.03.1(7)/4.03.2(7)
• Sections of BB Road and 2700 Road were previously reconstructed through the permit area in 2008,
and finished with gravel surfacing prior to being opened to the traveling public. The two roadways
were paved by an asphalt paving contractor on the day immediately preceding this inspection.
• Reconstruction of W 5th Ave. Road is nearly complete. The roadway template has been established
from the eastern permit boundary-westward,past Pond 007 (Photo 4). The roadway will be opened
to the traveling public at some future date. Signage and a gate will prevent the public from
mistakenly accessing the mine's NE Perimeter Haul Road.
RECLAMATION SUCCESS -Rule 4.15, Rule 3
• From the vantage point of the top of"Mount Nucla", we were able to observe the reclamation that
has been accomplished across the southeastern quadrant of the permit area (Photo 5), including the
Staats, Benson-South, Moore and San Miguel Power parcels.
• Sideroll systems were in operation in order to ensure that the soil is moist prior to the ditch being
turned off for the winter.
• The east and west branches of the reclaimed Krill Drainage have become well-vegetated with
wetlands-type species (Photo 6).
REVEGETATION—Rule 4.15 -Vegetative Cover, Timing
• As noted in the Aug-2010 inspection report, an area in the northwestern corner of the Irrigated
Pasture reference area has been undergoing treatment for mitigation of a stand of Quackgrass. The
affected area had been sprayed, and then plowed, in order to expose the roots to the warm
atmosphere for a period of time. Mr. Fry explained that the area has now been tilled and seeded with
the approved Irrigated Pasture mix (Seed Mix#5).
• With PR-6, approximately 25 acres of the Lloyd parcel is proposed to be irrigated using gated pipe
and furrows. The irrigation infrastructure is scheduled to be installed next spring, and the IP seed
mix will be planted.
