Wpt. of Natural Resources Re: Trinidad Basin Mining Inc., Final Contour Map and Partial Bond Release Mr. Michael 5. Savage ~~~~~~~~ Reclamation Specialist Mined Land Reclamation Division Q Colorado Department of Natural Resources Y6~ 1 ~~OIL 1313 Sherman St., Room 423 v C4O0 Denver, Colorado 80203 Dear Mike: Final reclamation has taken place on the Trinidad Basin mineslte since April 2,1985. Backfilling, grading and topsoil replacement has taken place on all required areas which include the previously open cuts in Section 15, the coal pad area, sediment ponds and haul roads. Ten sediment ponds currently exist on the site. If any are desired by the surface owners to be left as stock ponds, a revision concerning this will be submitted at a later date. Mulching and seeding has been taking place since mid-April and will continue until all areas are covered. 6y June 30, all mulching and seeding should be done. During the week of June 2-7, 1985, the minesite was surveyed to determine approximate final contour slopes, elevations, horizontal locations of pits, drainage, etc. ' In the permit, eight cross-sections were made on the original pre-mining slopes. These are listed as drawings V-1 though 8. Cross section locations are shown on Map V-1 titled "Premining Topography and Dates of Disturbance Map". In the areas of cross-sections 1-1', 2-2" and 3-3', no mining disturbance occurred, so these cross-sections were not re-surveyed. However, the other five cross-sections were re-surveyed. It must be pointed out that no exact locations for the original' cross-sections were given, therefore it is not correct to "accurately" compare the pre-mining and post-mining cross-sections because it is not known that the two sits of cross-sections were taken at exactly the same locations. The post-mining crass-sections can be used to identify final slopes, width and height of disturbed area, transition to undisturbed area, etc. The five enclosed cross-sections of the final contours are labeled as Drawings V-4F through 8F.
