STRIPPING: The initial year's mining area of 6.0 acres will be stripped to an
estimated depth of 2 feet and the topsoil stored in Stockpiles S3 and S4 (without
screening, but would probably be screened later in the mining sequence before
being used for reclamation). This would create a noise and visual barrier to the
south, which is the direction of the nearest houses (more than 500 feet distant).
The stripping will be done on a yearly basis for the first three years. The stripped
area will drain, with suitable erosion and sediment control in accordance with the
Surface Water Management Plan (SWMP), to an existing pipe which discharges
to the Dolores River.
INITIAL FACE WORK:
Mining will begin by the excavation of a ramp, from the stripped surface to a
depth of approximately 6-10 feet (for a total length of 250 feet to approximately
elevation 7208, in the eastern half of the area (Area 1A) for mining during Year 1
(southeast corner of the permit area). This level is chosen to allow continued
gravity drainage of any water collecting in the pit, through the existing pipe, in
accordance with the SWMP, and to prevent or reduce loss of ground water to
evaporation from ponds. Mining may be done in several lifts to reduce face
height, and allow for better drainage, but will be less than 10 feet.
During this period, the processing plant will be located on the western side of
Year 1's mining area (Area A2), which has been stripped but not mined.
Stockpiles of processed material will be located to create as much a noise barrier
as possible to the south of the processing plant. Waste material from screening
and washing will be placed in Stockpile S5, which will screen operations from the
highway, extending north from Stockpile S3.
The initial face will be expanded to include the entire southeast corner of the
permit area, ranging from 3.5 to 10.0 feet deep (5.5 to 12.0 below original ground
level), with the floor of the pit sloped at a 0.5% grade for drainage.
EXPANSION OF INITIAL FACE AND FIRST YEAR MINING
Once the upper level of the Area 1A is mined, the processing plant will be
relocated to that area, and Area 1B, (the western portion of Year 1, southwest
corner of the site) will also have the upper level mined. A sediment basin will be
excavated in the southeast corner of the site (south of the relocated plant),
approximately 250 by 150 feet and up to 20 feet deep, to improve drainage of
subsurface water and reduce sediment, as well as collect material from washing
of sand and gravel. This area will likely remain in open water from this period on,
and forms the basis of the permanent ponds on the site. During Year 1,
Stockpiles S1 through S5 wiil be built.
MINING OF THE UPPER LEVEL
In Year 2, mining of the central portion of the upper level will be done, stripping
and mining an area of 6.6 acres. After stripping 2 feet of soil, raw material will be
removed at a depth of from 5.5 to 10.0 feet (7.5 to 12.0 feet below original
ground level). The processing plant will be set up in the same location as in the
beginning of Year 1, near berms to reduce noise to the south. A drainage ditch
