unit will 6e evaluated on-site by an individual qualified to evaluate field observation • <br />tests including soil color, rooting depth, coarse fragment content, horizonation, and clay <br />content. Periodic field inspections will also be made by a soil scientist. Soil samples <br />will be collected to correlate field procedures with laboratory data. Topsoil recovery <br />depths viii be recorded on the soil map by the soil scientist to document the actual mean <br />thickness of topsoil recovered. Color photographs of the soil profile and landscape will <br />also be taken to verify topsoil salvage depths. This topsoil salvage depth information <br />will be kept on file at the mine and/or Ves tern Division office. Topsoil recovery depths <br />will be adjusted if warranted by the aforementioned quality control program. <br />The topsoil replacement thickness will be documented and recorded for each reclamation <br />block. The minimum sampling intensity to determine topsoil replacement thickness will be <br />one hole per five acres. This soil replacement thickness information will be used to <br />adjust topsoil salvage depths, if necessary, end for bond release purposes. An annual <br />Topsoil Balance/Spoil Quality Report will be completed to reconfirm topsoil volumes and, <br />if necessary, to readjust topsoil salvage depths through the life-of-mine operation. The <br />report will be submitted to CMLRD with the Annual Reclamation Report. <br />Qualitative monitoring for fertility will be done on all reclaimed areas as part of the • <br />ongoing revegetation success monitoring during the period of liability. Qualitative <br />monitoring for fertility viii include unscheduled visual observations of plant communities <br />throughout the reclamation area. More specific visual observations in conjunction with <br />soil sampling will be conducted et representative revegetation sampling locations. <br />Redistributed topsoil will not be tested for fertility by soil sampling unless obvious <br />problems appear in the reestablished plant Community. Obvious problems in the <br />reestablished plant community would include the identification of severe nutrient <br />deficiency symptoms including chlorosis of foliage, irregular spotting, scorching or <br />deformation of leaves, terminal dieback, stunted plants and seedling vigor, emergence, and <br />color. These determinations will be made on an annual basis during peak of green <br />revegetation monitoring. Unscheduled observations vould also be performed during periodic <br />evaluations of reclamation stand success, transact selection, or monitoring related to <br />bond release evaluations. <br />if fertility problems become evident, topsoil will, at a minimum, be sampled and analyzed • <br />32 Revised 04/24/91 <br />
