Re: Notice of Intent No. X-87-202-00, Drill Hole Abandonment Report and Final
Reclamation Report
Dear Mr. Davis:
The above referenced reports have been reviewed. Both are acceptable to the•
Division, although some questions arise from the Drill Hole Abandonment Report
in regard to Drill Hole No. 8. I interpret the report on this hole to
indicate a TD of 90 feet, the top of a water bearing zone at a depth of
75 feet, and cement plugs to have been placed between depths of 3 feet and
10 feet and between depths of 65 feet and 90 feet in the hole. Rule 4.07.3(2)
of the Regulations of the Colorado tdined Land Reclamation Board for Coal
Mining requires the sealing of water bearing zones not exhibiting artesian
flow at the surface with solid cement or other suitable media extending
20 feet above and below the zone. Accordingly if the top of the water bearing
zone was at 75 feet, the hole should have been sealed with cement or other
media up to a depth of 55 feet. The questions the Division has, therefore,
are 1). was the water level in the hole or the top of the water bearing zone
at 75 feet and 2). were drill cuttings or some other material used to fill
the hole between depths of 10 feet and 65 feet?
Sincerely,
Javrtpo C ~`~va
