2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -
MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS.
The existing mine transportation facilities and system were
utilized for the West Mine. Coal was transported from the West
Mine on a haul road to Steven's Gulch Road and from Steven's
Gulch Road to the East Mine coal processing facilities where the
coal was dumped into a grizzly and conveyed to the crushing and
screening facilities.
After coal processing, the coal was hauled from the East Mine
site to the storage and train loadout. No changes were made to
this existing transportation system.
The new West Mine haul road had been designed and was con-
structed to minimize erosion, downstream sedimentation, and
flooding. The road was constructed considering local topography
and anticipated volume of traffic. Road cuts were constructed
to minimize visual impact. The haul road drainage system
utilizes ditches and culverts as described in the Orchard Valley
West Portals Designs, Volume 6. Road cuts and fills were veg-
etated as stated in Section 2.05.9(2)(e).
There were no changes at the existing storage and loadout area
(See Volume 7). This area will continue to be used to store
coal fox unit train transportation. The loadout area will
continue to be used for unit train transportation. However, the
Operator temporarily stabilized the stockpile area in 2002.
In order to accommodate the need to stockpile run of mine lower
• quality coal, a temporary stockpile was constructed in the
timber storage area. The location of the stockpile,
(approximately 900' X 700'), is shown on Map No. SA-8, Surface
Disturbance & Orchard Valley West & Orchard Valley Mine
Facilities Map. While originally over 38,000 cu. yds. of rm~-
of-mine coal was stored here, only 17,000 cu. yds. remain. The
operator will place this remaining 17,000 cu.yds. of coal in the
backfilled slopes of the East Mine when it is returned to
approximate original contours. The operator will submit a
technical revision providing details concerning the method of
placement, the aerial extent of the placement, which benches are
affected, potential toxicity and an engineer's certification of
the factor of safety of the reclaimed benches with ROM material
placement.
This site was previously disturbed, pre August 3, 1977, and
subsequently re-vegetated. The subsoil existing at the site was
leveled and seeded, and presently supports a fair stand of
grass. Prior to placing the R-O-M coal at the site,
approximately 6" of the existing plant growth was stripped and
placed in windrows adjacent to the storage pad. The topsoil was
stabilized with the temporary seed mixture given in section
2.05.4(2)(e)(ii). The windrows contain a total of approximately
5,200 CY of plant growth material.
The R-O-M coal was hauled by 30 ton trucks to the stockpile site
via the existing road system. The short length of access road
from the main haul road into the storage area was tested by a
• geo-technical consultant to determine if is in adequate to
handle the proposed truck load. This report was forwarded to
the Division. Given the short term nature of the stockpile, and
