iiiiiiiiiiiiiiiiiii 999 STATE OF COLORADO DIVISION OF MINERALS AND GEOLOGY Department of Namrat Resources 1317 Sherman 51., Room 215 Denver, Colorado N0203 Phone: IJ031 866 3567 FAX:1303)AJ7-A106 DATE: January 30, 1996 TO: Larry Routten ~/J~- FROM: Dan Mathews ~!, /~~I RE: Roadside Annua/1 S/ubsidence Report Permit No. C-81-041 ~w•~" ~~~~~ DEPARTMENT OF NATURAL RESOURCES Roy Romer Governor James 5. Lochhead Eaecm rve DueU Or Michael B. Long Division Director I would like to request that Jim Pendleton review the attached report to verify that the information is sufficient to comply with the approved plan, and that observed effects are in accordance with projections. The monitoring plan is described on Page 239 of the application, a copy of which I have included. The report is limited to visual surface inspection, as the Roadside North subsidence monuments have apparently not yet been undermined (it would appear that SMO1 will be undermined this year). I have also attached copies of pages 224 and 225 from the application. These pages describe a recently constructed residence and irrigation structures which were constructed over mined out and active mining areas of the Roadside South Mine. What obligations does the company (and DMG) have with respect to such structures which were built after the permit was approved, and to a large extent, after mining had been completed in the area? Also, the annual report on Page 3 mentions a high voltage powerline in a portion of the Roadside South area to be mined in the near future (apparently the 6 East Panel in the vicinity of Rapid Creek). This power line is apparently not depicted on the "Man Made Features Map (Exhibit 46), and the report states the "powerline was installed subsequent to coal lease and was installed with the understanding that mining could subside the line." Does this facility need to be addressed within the subsidence survey/mitigation portions of the application? rside\95subrep.mem
