Colorado Backhoe Service Page 3 The Orr Pit- M-2009-074 Adequacy response #1 January 10, 2018 EXHIBIT D-Mining Plan (Rule 6.4.4): 6. The Exhibit D Mine Plan proposes a scale and scale house will be placed near the access point to the site. Please identify the location of the scale and scale house on the Mine Plan Map. Please also discuss the reclamation details of these structures. If the Applicant proposes to leave the scale and scale house as a part of the Reclamation Plan for the landowner's use, please provide a signed a notarized letter from the landowner(s)requesting for these features remain as a part of the final reclamation. Additionally, if the scale and scale house will be left as a part of the reclamation, please identify the location of it on the Reclamation Plan Map. The Mining Plan and Reclamation Plan maps have been revised to show the location of the Scale House and Scale . A notarize letter from the landowner is attached explaining how he wants the site reclaimed and confirms that the scale and scale house can to be left . 7. Within the Exhibit D Mine Plan (Page 8) and Exhibit E Reclamation Plan (Page 18), the applicant proposes to seed soil and overburden stockpiles which remain undisturbed for more than one year with a cover crop of western wheatgrass at a rate of 2 pounds-PLS/100 square feet. Later in the Mine Plan, on Page 9, the Applicant states a different species and seeding rate for this activity. Please correct this discrepancy. Upon further review, the Division believes this seeding rate is in error as it yields an extremely high seeds per square foot rate. The Division understands this cover crop seeding rate will be high to help prevent wind and water erosion on the soil and overburden stockpiles, however a rate more in the range of 40 PLS/acre of western wheat grass (yielding 101 seeds per square foot) would be more reasonable. I have corrected all areas in the text where we refer to the seed rate and type, to use western wheatgrass at a rate of 40 PLS per acre this is much more cost effective then the rate we proposed. Complete copies of Exhibit D with the changes, is attached for the file. EXHIBIT E -Reclamation Plan (Rule 6.4.5): 8. The Applicant proposes to leave the access roads as a part of the Reclamation Plan for the landowner's access to the site. Please provide a signed a notarized letter from the landowner(s) requesting for the access roads to remain as a part of the final reclamation for their access. Attached is notarized letter from the landowner stating that the existing road is to be left when the site is reclaimed.
