samples (rather than four). In this manner, each composite sample from all stockpiles will <br />represent no greater than 5 foot segments for sampling. <br />Soil Suitability Criteria /Requirements <br />OSM previously requested that WFC address the suitability parameters that will be used to <br />determine whether the materials are suitable for use in restoring prime farmland yields. <br />However, following receipt of the clarifications provided by DRMS during the October 25, 2011, <br />teleconference, OSM concurs that this determination is not needed at this time since TR -61 is <br />intended to address only the sampling plan. It is understood that further subsequent revisions to <br />the permit will be submitted to address all outstanding deficiencies identified previously by <br />OSM, including the suitability criteria issue. Therefore, this being the understood permitting <br />strategy, OSM agrees that there are no outstanding deficiencies identified in the suitability__ <br />requirements section for the TR -61 revision application. <br />In summary, two issues remain to be addressed: <br />1) Please clarify that OSM's understanding is accurate regarding the unsuitability <br />of stockpiled soils below the depth at which impermeable materials are <br />encountered with the probe, in instances where a new probe location is not <br />selected (as described above); <br />2) The sampling plan should include: For the Lift B stockpile boring's, the <br />number of soil samples taken from each probe should be increased from 4 to 8, <br />while these samples should be increased from 4 to 6 for the largest Lift A <br />stockpile. <br />Should you have any questions related to the issues discussed above, please contact me by phone <br />at 303 - 293 -5047, or via email at rlwilliamson@OSMRE.gov. <br />Cc: Steve Park, State Soil Scientist, NRCS <br />Sincerely, <br />Rick Williamson <br />Manager, Indian Programs Branch <br />
