or individual components if available, and ensure that such documentation is <br />retained and included in the Annual Reclamation Report in future years. <br />d) Report narrative addresses the number and species of shrub seedlings and 1 <br />gallon aspen saplings planted within three woody plant establishment areas (one <br />each in the "A" Pit, "B" Pit, and "D" Pit areas. Please provide additional information <br />including acreage of the individual planting areas, fencing if installed, and <br />type/size/source of seedlings and aspen saplings, (i.e. 10" containerized tubelings <br />grown from site collected seed, treated with mycorrhizal inoculant prepared from <br />Seneca Soils, etc.l. <br />Rule 2.04.1312) additional monitoring information required by approved permit <br />8. Permit Tab 20 commits to submittal of final graded topographic maps on an annual <br />basis, along with evaluation of consistency with the proposed postmining <br />topography. A November 2004 topographic map encompassing the regraded areas <br />was provided, but the map lacked certain detail including contour elevations and <br />contour interval. Also, the photo date is listed as 11/6/05, which obviously is <br />erroneous. Please provide an amended map with the requested correction and <br />detail. <br />The approved permit requires post-grading sampling on specified spoil and final <br />highwall regrade areas. Analytical results and evaluation for specified chemical and <br />physical parameters of concern are to be included in the annual reclamation report. <br />Within the original permit boundary, areas subject to sampling are delineated on <br />Exhibit 6-6 (Final Graded Spoil and Highwall Sampling Area). The subject area <br />includes most of the North mine block in the 005E-1 and 005 Gulch watersheds, as <br />well as the "B" Pit Area and adjacent portion of the "A" Pit Area, and the neck pit <br />area along the ridgeline between the North Block and the "B" Pit. The plan indicates <br />that the spoil sampling plan is to be implemented on regraded areas prior to topsoil <br />replacement (Tab 21, page 4). <br />In 2004, sampling was conducted within recently graded portions of the North Block <br />in the 005E-1 watershed, in a few locations along the lower 005 channel, and along <br />the southern boundary of the North Block area. Sampling was also conducted in the <br />recently graded "B" Pit and adjacent "A" Pit areas. The North Block areas had been <br />topsoiled prior to spoil sampling (2003 in 005E-1 watershed; 1999 along south <br />highwall). Remaining areas were topsoiled and seeded in 2004. The "A" and "B" <br />pit sampling appears to have been conducted in general accordance with the <br />systematic grid, 500 toot spacing specified in the permit, for the recently reclaimed <br />areas. However there is an apparent gap in the North Block sampling grid in the "D" <br />and "C" Pit areas, between Samples 40 and 41, and the line of samples from 35 <br />through 39. Also, no samples were taken from the graded highwall slope north of <br />Channel 005-E1, though it appears that at least one and possibly 4 sample locations <br />would have fallen within this area, based on a 500 foot grid. Finally, there are no <br />samples from the older reclaimed areas of the upper "B" Pit and along the ridgeline, <br />between "B" Pit Sample #5, and "C" Pit Sample #35. <br />a) Please explain the reason for the apparent gaps in the sampling grid in these <br />locations. It may be that the older reclamation where there are apparent gaps were <br />sampled previously. If so, please provide reference to the report or reports that <br />include the sampling documentation. <br />
