Box 628 Nucla, CO 81424 Re: Review of 1995 AHR for New Horizon Mines 1 & 2, Permit No. C-81-008 Dear Mr. Gubka: ~.~ I~~~~ f~EPAR"I'MENT OF NATURAL RESOURCE Koq Kumcr Gnvemo. ~.uur.1 Luc hhrad Eaecmive Direelnr NirharlB Inng Ui. nwn Un, , irn The Division has reviewed the New Horizon Mine 1 and 2 permits and the 1995 AHR, and found numerous discrepancies existing within the permit, and between the permit and the AHR. These discrepancies made it diffcult to determine exactly what the New Horizon Water monitoring and analysis program is. Because of these discrepancies, it was also difficult to determine if Western Fuels is conducting its approved water monitoring and analysis program. The following discrepancies need to be resolved. 1. Two sections of permit text exist in the Tab 15 section of Volume F. The first section runs from Pages 15-1 to 15-18. The second runs from 15-19 to 15-24. The information in both sections needs to be revised to be consistent with each other and reflect the currently approved plan. 2. Appendix 15-1 has been removed from the permit but a page noting where the information from appendix 15-1 can be found since it is referred to in several place in Tab 15. 3. In the first paragraph on Page 15-4, it is stated that "the full suite (surface) water quality analysis (for Mine 1) has been changed from monthly to semi-annual". On Page 15-20, however, Table 15-7 lists the frequency for full suite analysis as for Mine 1 quarterly, rather than semi-annual. Please revise this to the correct frequency. 4. In the second paragraph on Page 15-4, a portion of a sentence reads "...water level recorders at sites SW-N104 and SW-106 measure water level stage in the west lateral irrigation ditch...". On Page 15-21, however, in Table 15-7, the permit indicates the two West Lateral Ditch monitoring stations are SW-N 104 and SW-N105. SW-N 106 is not listed in either Table 15-7 of the permit or Table 1 of the 1995 AHR. Please correct these discrepancies.
