PERMIT #: M-2000-066 <br />INSPECTOR'S INITIALS: MAC <br />INSPECTION DATE: March 16, 2011 <br />OBSERVATIONS <br />The inspection was conducted by Michael Cunningham of the Division of Reclamation, Mining and Safety <br />(Division). Kenneth Morrison of Lincoln County was also present for the inspection. The Raymond Enderson Pit <br />is located approximately 12 miles north and 2 miles west of Arriba, Colorado. The site is permitted for 9.9 <br />acres and the post-mining land use is rangeland. <br />Gen. Compliance With Mine Plan: <br />This pit is no longer being used by Lincoln County; the site was last mined in 2007. The Operator should be <br />aware that Construction Materials Rule 3.1.3 states reclamation shall be carried to completion by the <br />Operator with all reasonable diligence, and each phase of reclamation shall be completed within five years <br />from the date the Operator informs the Division that such phase has commenced. <br />Reclamation Success: <br />Mining at the Raymond Enderson Pit primarily took place within the channel of the Arickaree River. The river <br />channel has filled in with sediment with each successive precipitation event; there is no evidence of a pit <br />within the channel. The banks of the Arickaree River are stable and did not show any signs of erosion. The <br />load-out area north of the Arickaree River has been graded and seeded with the approved seed mix; the <br />majority of the revegetated area contains a healthy stand of blue grama. There are a few small areas outside <br />of the river channel that are bare or kochia infested. The Operated has indicated the kochia infested areas will <br />be treated with Trimec and seeded with the approved seed mix this spring. The Operator should ensure that <br />any herbicides used on the site have been approved for use near aquatic areas. <br />Signs and Markers: <br />Permit sign was posted at the site entrance in accordance with Rule 3.1.12. <br />This concluded the inspection. <br />Inspection Contact Address <br />Kenneth Morrison <br />Lincoln County <br />103 3rd Ave. <br />Hugo, CO 80821 <br />Page 2 of 3
