iii iiiiiiiiniii iii <br />999 <br />ECG NECA <br />s Coa/Company Seneca Coal Company <br />February 17, 1997 <br />FfB 191997 <br />Ms. Erica Crosby <br />Division of Minerals and Geology ~ „u,,,,,,,,,,,;;~~„~~~oiogy <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203-2273 <br />RE: Seneca II-W Mine Permit C-82-057, 1996 Stocktank As-Built <br />Reports <br />Dear Ms. Crosby: <br />Pursuant to Rule 4.05.6(10), please find enclosed the certified As- <br />Built reports for the stocktanks which were constructed at the <br />Seneca II-W Mine in 1996. Reports are enclosed for the following <br />Structures: T-2, T-3, T-7, T-22 and T-24. <br />Along with the as-built report for each stocktank, a copy of the <br />actual survey data is included. For future submittals, Seneca will <br />provide the Division with this data in digital format on a floppy <br />disk. We will be happy to provide either a file with the x,y,z data <br />or in a DxF file format, whichever the Division would prefer. These <br />are the first set of stocktanks at Seneca which were surveyed <br />utilizing our GPS system. <br />it should be pointed out that the Basin Elevation-Stage-Area- <br />Capacity Tables for stocktanks T-7 and T-22 are not completed. Our <br />digitizer has coughed-up-a-lung and we are in the process of having <br />it put to rest. The areas need to be digitized for the various <br />elevations, so the tables can be computed. Seneca will send these <br />to the Division as soon as we have a new functioning digitizer at <br />the minesite. <br />Please contact me if you or any other members of the Division have <br />any questions concerning the enclosed materials. <br />Sincerely, <br />Michael G. Altavilla, P.E. <br />Engineering Manager <br />Enclosure(s) <br />c: Gary Wendt(PWCC) <br />Seneca Coal Company • P.O.
