Dear Ms . Thompson:
By letter from George Wear dated January 29, 1986, Mid-
Continent Resources (MCR) agreed to four stipulations
proposed by the Division (CMLRD) as conditions of approval
for MCR 's Technical Revision application of November, 1985,
to suspend subsidence monitoring. Stipulation no. 3
accompanying CMLRD's February 1986 approval of this
suspension required resurvey of existing monuments at the
end of the current 5--year permit period, i .e . during the
summer of 1988. This survey has been completed and the data
submitted to your office by letter dated September 26, 1988;
please advise if you have not received this information.
Stipulation No . 1 st tes " [ ilf any unanticipated surface
disturbance (crackin , cratering or landsliding) manifests
itself within the ar potentially affected by subsidence
(angle of draw = 20 . ) , the operator will be required to
immediately reinstitute the subsidence monitoring program. "
Implicit in this statement is notification to CMLRD by MCR
of the discovery of uch surface disturbance(s) .
During the survey pe formed in accordance with Stipulation 3
on August 8 and 9, 1 88, two cracks were noted on Huntsman
Ridge between the south fork of Coal Creek on the east and
Rock and South Twin Creeks on the west . These cracks were
not observed when th s area was examined by survey crews,
MCR environmental an engineering personnel, and the writer
during the summer an fall of 1985. Time constraints and
deteriorating weathe conditions did not allow close
examination of these features during the 1988 survey. The
area was subsequently examined by George Wear, acting as a
special projects consultant to MCR, and the writer, on
foot . While the day selected started out cool and dry,
thunderstorms were f rming by the time the area of interest,
2 . 5 miles from the n arest road access, was reached, and the
features could only a sketch-mapped before weather
conditions forced re neat . Thus the following descriptions
should be considered general, and all calculations
concerning apparent angles tentative . All angles are
