Ms. Welt <br />Page 7 <br />12. Stipulation 8 from the 1986 Permit Renewal, requires MCC to <br />complete surface and ground water monitoring of the lower waste <br />pile and to included chemical constituents selenium, unionized <br />ammonia, and nitrate/nitrite. Results were to be included in <br />quarterly hydrology reports. MCC's Annual Hydrology Reports are to <br />include seasonal changes for all chemical constituents (surface and <br />ground water) monitored during the year. The AHR is also to <br />include an assessment of the impacts of the lower waste pile to the <br />hydrologic balance during the previous year. The Division's <br />records show this stipulation as active. Please respond to the <br />following so we can reconcile this stipulation. <br />A. The last quarterly hydrology report was received for third <br />quarter of 1987. Is the lower waste pile still monitored <br />quarterly? If not, why not? <br />B. It appears that the chemical constituents selenium, <br />unionized ammonia, and nitrate/nitrite are no longer monitored. <br />Please explain. <br />C. Upon review of MCC's 1991 Annual Hydrology Report, it was <br />found to be in compliance with the second part of the stipulation. <br />12. Stipulation 14, 15, 16 or stipulations 15, 16, 17 from Permit <br />Revision 4, concerning photogrammetric surveys shows a status of <br />forgiven. It appears that MCC revised this plan to only use the <br />northern half of the subsidence grid for aerial photogrammetric <br />monitoring techniques. If this is the case, the stipulation should <br />be revised or incorporated into the permit. If there is more <br />documentation concerning this issue, the Division would request <br />MCC's assistance in order to reconcile this stipulation. <br />13. Stipulation 20 from the 1986 Permit Renewal requires MCC to <br />limit extraction within defined "critical area buffer zones" <br />beneath Dry Fork of Minnesota Creek and Lick Creek to no more than <br />thirty percent of the in-place coal. The Division shows a status <br />of terminated but cannot locate the documentation. The Division <br />would request MCC's assistance to reconcile this stipulation. <br />14. In a letter contained within the stipulation file, Mr. Hayes <br />describes Stipulation 34 which requires MCC to collect at least one <br />composite, representative sample of the discharge water from the <br />old portal and to have it analyzed for specific parameters. The <br />results were to be forwarded to MLRD. Unfortunately, I cannot find <br />any mention of this stipulation in other documents, nor can I find <br />the test results. Please provide information regarding this <br />stipulation. <br />15. In a letter contained within the stipulation file, Mr. Hayes <br />describes Stipulation 36 which requires MCC to submit various <br />reports within 30 days after each calendar year to the BLM Chief <br />Branch of Solid Minerals. These reports relate to drill holes and <br />monitoring wells, and well completion data. The note mentions that <br />this stipulation was originally attached to Minor Revision 5 as <br />
