will be windrowed/temporarily stockpiled adjacent to the pad. Following completion of the well work, a portion of
the expanded area may be reclaimed, with remaining topsoil being added to the existing topsoil stockpile. The
• topsoil and reclaimed area will be seeded and stabilized using the pastureland see mixture.
Railroad Spur Extension azea -covers 2.75 acres and is located west of pinnacle Peak adjacent to the railroad
embankment. A portion of this exemption is a seeded topsoil stockpile. All water drains to the south and is filtered
through a silt fence located west of the extension. The azea below the silt fence is vegetated and serves as a
vegetative filter. Peak flow from this small area is approximately 4.4 cfs, as previously approved in the original
submittal under the C-81-071 permit.
Wazehouse/shop area -covers 5.88 acres and is located on a north facing slope below the shops. Water
(approximately O.15 acre feet from the 10 year-24 hour event) drains through established vegetation, gathers along
the railroad track embankment and runs along ditch F-2 toward the culvert under the light-use road adjacent to
Pond F. The water impounds before the culvert before flowing through the culvert. Once through the culvert it
will flow down the north side of Pond F and the light-use road/raitroad embankment. The area is vegetated and
serves as a vegetative filter to inhibit flow. There will also be a rock check dam, which will additionally filter
surface runoff prior to exiting the site.
Stoker Coal Loadout - which covers 1.8 acres and is located north of the Old Equipment Parking Lot and adjacent
to the railroad tracks. Sediment control in the area consists of a berm and rock filter located on the west side of the
bench, and a rock filter on the north side of the railroad track. This will control any potential surface runoff from
the bench area.
Warehouse Area #2 -this small area consists of approximately 1.5 acres located between the Stoker Pad exemption and
the Warehouse/Shop exemption. Drainage from this area is for the most part dead (i.e. static), and any flow from the
area would be serviced by either the Stoker Pad silt fence or the warehouse exemption rock check dam.
• TIDDIe #2 Loadout tunnel -which consists of small disturbed area surrounding the tunnel on the east side as identified
on Permit Renewal Map 5 (Roads, Powerlines and Facilities). The surrounding area is well vegetated and rock/gravel
fiber dams have been installed in the ditches along the railroad track. This small area exemption was approved by the
CMLRD on June 23, 1988 with MR 88-27. Runoff from this 0.10 acre exemption would be negligible from a 10 yeaz-
24 hour event.
Pond B access Pad -comprises some 0.3 acres adjacent to Pond B. The area is gently sloping, with heavy vegetative
cover on adjacent areas bordering Foidel Creek, acting as a filter to prevent sediment contribution to the stream. CYCC
will also constmd a bens and rock Sher to fiuther control and treat the anticipated 0.01 acre feet of runoff; which may
be generated by the 10 year-24 hour event.
Pond D east area - covers 0.7 acres adjacent to the emergency spillway, overland conveyor, and the hauhoad. Runoff
from this area flows along the haulroad, and collects between the haulroad and the Pond D embankment immediately to
the east of the culvert, which conveys Pond D discharge to Foidel Creek. The area is vegetated, and will leave a sump
and rock filter to treat the anticipated 0.04 acre feet of nuwff, which may be generated by the 10 yeaz-24 hour from the
SAE.
Pond D west area -covers 0.7 acres between the hanlroad and pond embanlattent discharge point, along with a portion
of the overland belt. CYCC proposes the use of a rock filter to treat any of the anticipated 0.04 acre feet (10 yr24 hr)
of runoff from the area.
Pond F and Waste Water Treatment Facility -covers approximately 5 acres and is located southwest and northwest of
Pond F and consists of 0.5 acre paved pazking lot and slope which drains down to the west embankment of Pond F and
• the outslopes and tops of the ponds of the waste water treatment system. Also, the building and roads associated with
the treatment facility are located in the SAE. The building pads and roads are graveled, which minimize the potential
for sediment to leave the area. Water can potentially drain along the north side of Pond F and light-use road railroad
