RULE 2 PERMITS
3. Drill holes with no water or coal zones may be plugged by backfilling with cuttings, and
placing a plug ten feet below the ground surface to support a cement plug or bentonite
chips to within 3 feet of the ground surface.
For safety considerations, exploration drill holes that will eventually be mined through during
normal mining activites need only be covered with wood, plastic or other such material or
otherwise bermed to prevent access until mining operations mine through each hole.
Those holes completed in aquifers will be sealed entirely with cement or other suitable sealant to
within 3 feet of the ground surface.
Where possible, the sealed holes will be marked. At times reclamation operations will cover up
the sealed drill holes and marking of holes will not be possible.
Within 60 days of the abandonment of a drill hole, approved drilling program or when requested
by the Division, the following information will be submitted:
a) Location of drill hole as plotted accurately on a topographic map.
b) Depth of drill hole.
c) Surface elevation of drill hole.
d) Intervals where water was encountered during drilling activities.
e) Diameter of drill hole
f) Type of amount of cement or other sealant used.
g) Name of drilling contractor and license number of rig.
h) How the hole was worked.
Exploration taking place inside and outside of the permit area will be handled through the Notice
of Intent(NOI)procedures. See the appropriate NOI for details for each program.
Water and Air Quality Control Techniques
Steps to be taken to comply with the Clean Water Act and other applicable water quality laws and
regulations and health and safety standards include a comprehensive drainage and sediment control
plan described in Section 2.05.3 and Sections 4.05.1 through 4.05.18. With respect to compliance
with the Clean Water Act, Colowyo has a discharge permit from the Colorado State Department
of Health under the National Pollutant and Discharge Elimination System (NPDES). Compliance
with this permit will serve to effect compliance with the Clean Water Act and the Colorado Water
Quality Control Act. A copy of this submittal is presented in Exhibit 7, Hydrology Information.
Colowyo, likewise, operates under several emission permits from the Colorado Department of
Health, Air Pollution Control Division. Fugitive dust control measures will be employed as an
integral part of the mining and reclamation operations.
Colowyo conducts air quality monitoring at the site in accordance with the requirements of
emission permits approved by the Colorado Air Pollution Control Division. A copy of all
applicable emission permits has been included in Exhibit 8 of the application.
