<br />TMI topsoil evaluation, oe. 2 <br />We compared these maps to actual field locations on Oct. 12, 2005. We also completed <br />representative topsoil replacement (depth) checks by digging holes on the 2005 topsoil <br />replacement areas on October 12, 2005. We also observed the CY 2005 topsoil removal areas, <br />and the ongoing topsoil stockpile relocation-redistribution effort using the ash haul end dump <br />trucks. All topsoil depth measurements taken of the 2005 topsoil replacement areas at the F Pit, <br />the Z Pit, and the former explosive area (these were the 3 areas evaluated for topsoil <br />replacement) were equal to and more than the required 12 inches plus or minus 2 inches (no <br />cropland replacement was completed or evaluated on this inspection, and this land use exists <br />primarily on previous reclamation areas at TML). <br />From our field work and observations, it appears topsoil is being handled to reduce compaction <br />and contamination, regraded land is ready for topsoil, and replaced topsoil is being protected <br />from wind and water erosion. We discussed final surface texture differences between some of the <br />CY 2005 topsoil replacement areas. Some areas are "rougher" that others and this practice <br />reduces surface water runoff and provides micro clime for plant establishment. TMI is trying to <br />get all CY 2005 topsoil replacement areas seeded during October 2005. We also discussed <br />possible seeding into snow cover on some of the CY 2005 topsoil replacement area to evaluate <br />the results from that different seeding practice. <br />Mrs. Binns and I both took GPS point readings of the topsoil depth-sampling locations at the <br />three replacement areas noted above. Mrs. Binns intends to document these sampling findings <br />and locations as data references for future use including bond release and reclamation success <br />findings. <br />Please address any questions concerning this report to Henry Austin at haustin@osmre.QOV or to <br />(303)844-1400 x 1466. <br />
