per map unit or five acres whichever is less." The Morgan property is adequately <br />sampled on a 330 ft2 grid (2.5 acres as per PR-6) but the remainder of the mine is <br />sampled on a 600 ft2 grid (8.26 acres) which is too large an area by either standard. <br />The areas north of BB Road that were backfilled in 2009 and 2010 should be <br />sampled on a 465 ft2 grid (5 acres). <br />6. Exhibit 2010-10, 2010 Topsoil Soil Balance - Pease clarify or correct the discrepancies <br />listed below for this map: <br />a. In the chart Morgan Soil Back Fill Calculations, the calculations for square feet do <br />not equal the acrear for the corresponding Zones 2 and 3. Zone 2 is 12.21 acres <br />which is 531,868 ft (43,560 ft /ac) but is listed as 521,529. Zone 3 is 31.68 acres <br />which. is 1,379,981 ft2, but is listed as 1,256,371. Please explain the differences in <br />area. <br />b. The chart `Morgan Soil Back Fill Calculations' is not calculating backfill but rather <br />topsoil. Please rename chart `Morgan Topsoil Replacement Calculations.' <br />c. The chart `Required Morgan Backfill' is not calculating backfill but rather topsoil. <br />Please rename chart `Morgan Topsoil Balance.' <br />d. Please include another chart showing the `Non-Morgan Replacement Calculations.' <br />Include in the chart the calculations (acreages and soil depth) used to determine the <br />required fill values used in the "Required Backfill Non-Morgan' chart. <br />e. Add to the legend of the map: the honeycomb pattern in BB Road and the grey OB <br />figures. <br />T Annual Reclamation Report 2010, page 3, Cover Crop, I" bullet - The text says seed mix <br />#3 was applied at a rate of 22.5 PLS/acre. Were 22.5 pure live seeds (PLS) applied per acre <br />or was this a typo meant to say lbs/acre? Please address this same issue in the next bullet on <br />page 4. <br />8. Annual Reclamation Report 2010, page 4, New Field Seeding and Interseeding - It is stated <br />that the "Benson west" property was seeded. Actually, "Benson east" was seeded. Please <br />fix this typo. <br />9. Annual Reclamation Report 2010, page 5, Land Status Category Chart -In the `Last Year's <br />Cumulative Total' column, the total acreages forwarded from the previous years are the <br />same for 2008, 2009 and 2010. Also, the cumulative totals are the same for 2008 and 2010. <br />Please check all the values in this chart by verifying the completeness of the data. <br />10. Annual Reclamation Report 2010, page 5, Acres Seeded Chart <br />-The acreage addition in <br />`Last Year's Cumulative Total' column is incorrect. The 319.91 acres forwarded is the <br />same value used for 2008, 2009 and 2010. The chart list 0.0 acres seeded in 2010, but in <br />fact 34.9 acres were seeded. Please check all the values in this chart by verifying the <br />completeness of the data. <br />11. The following comments pertain to the Walsh Soil Suitability Study included with the 2010 <br />Annual Reclamation Report (ARR). At the time of the soil sampling (August 2010), <br />suitable soil standards were outlined in the permit by TR-57, however, during this time, a <br />3
