As we discussed on Friday, September 24, 1993, I have completed my review of the
subsidence data submitted as required by your approved permit, No. C-82-056.
That review revealed the following:
1. Baseline data for lines A-A' and 8-B' was not collected one month prior to
the commencement of longwall mining as required by your permit, and Rule
2.05.6(6)(c)(D).
2. One week of data collection was not done between 12/22/92 and 1/7/93
(15 days).
3. Line A-A' was not completely surveyed each week as required by your permit.
4. Additionally, the semi-annual submittal was pe
tardy, having been received by the Division in

Therefore, we have issued Violation No. C-93-137 to
the Foidel Creek Mine. Please find the appropriate
You have 15 days from the time of service to submit
