Ms. Welt Page 7• 12f1 Stipulation 8 from the 1986 Permit Renewal, requires MCC to omplete surface and ground water monitoring of the lower waste pile and to included chemical constituents selenium, unionized ammonia, and nitrate/nitrite. Results were to be included in quarterly hydrology reports. MCC's Annual Hydrology Reports are to include seasonal changes for all chemical constituents (surface and ground water) monitored during the year. The AHR is also to include an assessment of the impacts of the lower waste pile to the hydrologic balance during the previous year. The Division's records show this stipulation as active. Please respond to the following so we can reconcile this stipulation. A. The last quarterly hydrology report was received for third quarter of 1987. Is the lower waste pile still monitored quarterly? If not, why not? B. It appears that the chemical constituents selenium, unionized ammonia, and nitrate/nitrite are no longer monitored. Please explain. C. Upon review of MCC's 1991 Annual Hydrology Report, it was found to be in compliance with the second part of the stipulation. 12LJ Stipulation 14, 15, 16 or stipulations 15, 16, 17 from Permit Revision 4, concerning photogrammetric surveys shows a status of forgiven. It appears that MCC revised this plan to only use the northern half of the subsidence grid for aerial photogrammetric monitoring techniques. If this is the case, the stipulation should be revised or incorporated into the permit. If there is more documentation concerning this issue, the Division would request MCC's assistance in order to reconcile this stipulation. ~- ~'4 l~'j'~ 13~ Stipulation 20 from the 1986 Permit Renewal requires MCC to i~mit extraction within defined "critical area buffer zones" ~~ ~~~~~~ eneath Dry Fork of Minnesota Creek and Lick Creek to no more than L~~CJ~I~~w~A~hirty percent of the in-place coal.
