Munger &McClane Canvon Mines, ma. 2 We proceeded to the McClane Canyon Mine office where we identified ourselves and indicated we would continue by first inspecting the Munger Canyon Mine. The primary focus of the Munger Canyon inspection was to evaluate temporary cessation findings znd any offsite impacts which might be occurring. According to inspection participants, the haulroad into this site and the limited portal face up work done here was all completed pre SMCRA and the mine has never commercially produced coal, nor has it been active under a permanent program permit. The temporary cessation notification to DMG is dated January 17, 1984, and is outdated. Mr. Matthews will request an updated notification during the July 2000 midterm permit review. Mr. Matthews, myself and Mr. Jenkel reviewed and discussed a "Temporary Inactive Status Review Checklist" which the Team agreed we would use as a guide on these special focus inspections to help document past and present conditions, and future plans for these sites. The checklist is not an official or approved permitting or inspection document, but simply a guide as indicated. Please address any questions concerning the checklist to Mr. Matthews or myself. Mr. Jenkel was provided a copy of the checklist, and we noted several questions and requests for information which Mr. Matthews will follow up through the July 2000 midterm review process. It appears from our discussions that the three portals were temporarily sealed during 1992 and remain sealed. Mr. Matthews has notified the permttee that when the haulroad conditions allow the three portals should be backfilled outby the temporary seals or otherwise treated to further restrict access. Primary drainage control is adequate, and the approved SAE's are functional. There were no offsite impacts noted from the portal area. There was a major storm event in this area during 1997 and some evidence still of severe surface water runoff both on and off'the disturbed azea(s). Mr. Matthews will address additional protection (seeding) of the soil materials available on the site during the midterm permit review. The synthetic sleeves attached to the haulroad culverts were inspected as were inlets/sumps along the road and they were adequate. Mr. Matthews notified Mr. Jenkel about some necessary road ditch maintenance between culverts 4 and 5 (rock falls), and a portion of the sleeve on culvert 4 needs repair. Mr. Jenkel met us as we were leaving the site, and we discussed surface and ground water monitoring requirements at the sites, Mr. Jenkel was conducting water sampling on both sites during our inspections. There were no off site impacts noted at the Munger Canyon Mine. We collected some information to help us evaluate the temporary cessation status of the site, and Mr. Matthews will collect additional information during [he midterm permit review as noted above. It doesn't appear there are any plans to activate the mine for any reason in the foreseeable future. The Team will utilize all sources of information at the end of this evaluation year to conclude our special focus study on temporary cessation. This concluded the special focus inspection. We returned [o the McClane Canyon Mine and began our complete inspection there by inspecting all the disturbed areas. The new permittee here, Loadstar Energy, lnc., notified the DMG during December 1999 that coal production would resume at [he mine, and coal production actually began approximately February 2000. Coal is currently being stockpiled at the portal/main mine facilities area and a truck turn around is being utilized to haul coal to the Cameo Power Plant east of Grand Junction just off Interstate 70.
