Dear Mr. Gosney, DIVISION OF MINERALS GEOLOGY RECLAMATION MIN ING•SA FE TY Bill Owens Governor Greg E. watcher Execwive D~re<tor Michael B. Long Division Dnector I have reviewed the above-named application, which was submitted to our office on your behalf by Southwest Land Services, Inc. Overall the application materials and the several additional submittals appear well-prepared and meet most of the requirements of the application. However, f have a number of questions which should be ansvered to provide clarification to the application form and its exhibits. These items are listed below in the order of the application item or exhibit to which they pertain. A few of the listed items included below are simply my restatement of your information according to my understanding; if I have correctly interpreted your information no additional comment by you is needed, and the item may be considered to be adequate. Items in [he application package to which there is no reference herein are considered at this time [o be adequate. Exhibit C -Pre-mining and Mining Plan Map This exhibit submittal consists of two map sheets, "one of hvo" and "two of two." Sheet one of hvo contains numerous inadequacies. It does not include enough space on the sheet to depict the full western boundary of the proposed permit area, nor space enough to include any adjoining landowners' names on the west side, nor on the northwest or southwest. During the pre-operation inspection an additional road was observed, which is not depicted on the map. It appeared to be a gravel led, private road which provides access [o the adjacent land to the south of the permit area. It extended to tlme SSE from the utility corridor at the top of the ramp road which enters tlme permit area from the SE. It exited the property via a cattleguard at the south fenceline. It should be added to this map (and to the reclamation map if appropriate), and identified as a significant structure elsewhere in the application. The stormwater control bernm depicted on the eastern edge of the affected area and as cross-section A-A' is given fimrther explanation elsewhere in the application. Please describe whether it is to be native material left wmexcavated, or aggregate material placed as fill. Please be reminded that it is not advisable to use topsoil as the fill for stormwater controls, due to the risk of degradation and loss prior to reclanmation. The site is presently covered in pinyon juniper woodland with intermixed rangeland vegetation. As time site is stripped in preparation for mining, tlmere will be large amounts of woody debris generated, vvhiclm will have [o be placed somewhere and handled somehow. Please show the stockpiling or disposal locations for this material on the nmap. This information may affect tlmc bond estimate, since it involves a disturbance to reclainm.
