• PRE-DRILLING ACTIVITIES
Prior to any construction or drilling activities, an on-site inspection of proposed drill sites
and access routes will be conducted with representatives from appropriate regulatory
agencies to discuss site-specific concerns. Proper Road Use and Special Use permits will
be modified if required by the U.S. Forest Service for use of the roads. It is anticipated
that initial snow removal may be required.
CDMG, USFS, and BLM regulatory personnel will be notified at (east 48 hours before
any construction or drilling equipment is mobilized into the project aeeas. Construction
and drilling activities will be supervised by a representative of Mountain Coal Company.
A copy of the approved permit documents will be available from the company
representative for inspection. Any proposed changes in the Project after permit approval
will be reviewed with the appropriate regulatory agencies before changes take effect.
Staging areas to be used by the drilling contractor will be reviewed with and approved by
the USFS District Ranger or his representative prior to use. These sites will be used in a
manner to minimize damage to the vegetation. Any surface disturbance to these sites will
be re-graded and seeded to promote rehabilitation.
Access to all drill sites will utilize existing roads and trails. All access routes will be
maintained to accommodate 4X4 pickup tn~cks and a drilling unit. A drilling unit is
• defined as encompassing part or all of the following equipment: truck mounted or skid
mounted drill rig, air compressor and\or booster, rig-up truck, boom truck, utility trailer,
drill pipe laydown rack, crew trucks, and water trucks.
Roads utilized in the project will be maintained with water bars and appropriate
sedimentation controls as required during the drilling phase. A D8 bulldozer or its
equivalent will be used to prepare the road for travel and assist in mobilizing the drill
equipment to the drill sites. Additional equipment expected to be used in opening,
maintaining, and reclamation may include a rubber tired backhoe, rubber tired grader, and
a track mounted baekhoe.
The Gob Vent / De-gas Borehole pads will require reopening of the West Flat Iron road
as previously discussed. The road would be maintained at a 12 foot width. Movement of
equipment across undisturbed land would be kept to a minimum. No brush or tree
removal is anticipated on the access route. Drill site pads of a maximum size of 100' x
200 ft. will be constructed to accommodate the drill equipment and drill cuttings sump.
Drill pads will be constructed only as large as necessary. Topsoil will be stripped,
stockpiled, and identified with a sign to be used in the reclamation phase of the program.
Mudpits to accommodate drill cuttings will be constructed with an approximate size of
10' x 20' x 6'.
Water for the drilling operations will be hauled to the site from stock ponds along the
• road at the western base of West Flat Iron Mesa (locally known as Two Ponds), or hauled
from the stock ponds along the USFS Road 711a, located west oti the junction with USFS
