Hydrologic Balance, Page 3 of 10, Carbon Junction Channel, On October 7, 2010, Chi <br />Chi Ray, president of Oakridge Energy and I met with John Gilleland and Aaron <br />Chubbick of C&J Gravel to discuss repair measures to the noted hole in the channel. On <br />October 27, 2010, Mr. Chubbick called to confirm that repairs to the hole had been <br />completed. The repairs included fill of the hole with native material to the base level of <br />the channel, installation of a geotextile liner at the channel base level in the area of and <br />above the hole, and placement of durable rock riprap of the size consistent with that <br />already lining the channel. <br />Hydrologic Balance, Page 4 of 10, Reclaimed western collection ditch. It should be <br />noted that the metal "T" posts that identify the boundaries of the Carbon Junction Mine <br />have been in place at the area in question for at least five years. On October 6, 2010, I <br />installed or replaced Carbon Junction Mine Permit Boundary signs in the area in <br />question. Not every "T" post boundary marker has a sign, but the "T" posts are visible <br />from each other. Several Carbon Junction Mine Permit Boundary signs were added in <br />the area north of the Equipment Area, and at the entrance to the Equipment Area and <br />Ewing # 1 Mine permit area. <br />Revegetation, Page 4 of 10. As a point of clarification, Pond 1 was backfilled, graded <br />and topsoiled in November and December 2008, as was Pond 002, and the sediment <br />control diversions adjacent to the ponds. Revegetation took place during the first seeding <br />window after the earthwork was completed in April and May 2009. <br />Slides and Damage, Page S of 10. As discussed in my correspondence of August 27, <br />2010, Oakridge Energy and I disagree with the Division's observations regarding the <br />crack at the North Pit and the "bulge" at the Previously Reclaimed Spoil Area. <br />Signs and Markers, Page S of 10. It should be noted that the metal "T" posts that <br />identify the boundaries of the Carbon Junction Mine have been in place at the area in <br />question for at least five years. On October 6, 2010, I installed or replaced Carbon <br />Junction Mine Permit Boundary signs in the area in question. Not every "T" post <br />boundary marker has a sign, but the "T" posts are visible from each other. Several <br />Carbon Junction Mine Permit Boundary signs were added in the area north of the <br />Equipment Area, and at the entrance to the Equipment Area and Ewing #1 Mine permit <br />area. <br />October 6, 2010 Inspection Report <br />The inspection report notes that the inspection started on October 6, 2010 at 3:10 PM and <br />concluded at 5:30 PM. The time signatures on photographs of my repairs at the Carbon <br />Junction Mine indicate the repairs were undertaken between 10:30 AM and 12:30 PM on <br />October 6, 2010, yet the boundary sign concern remained and was noted in the October <br />inspection report. Figure 1 (appended) indicates that a boundary marker was clearly in <br />place at the culvert end (southwest side of the Ewing Mesa #1 permit area) at 12:30 PM <br />on October 6, 2010, yet the photograph appended to the inspection report does not show <br />the sign, nor is there any indication of the signage in the text. Please explain. <br />Comments, Page 2 of 9, Paragraph S. The statement in the first sentence is incorrect. <br />Oakridge Energy never specified specific areas within the coal mine permit area for the <br />approved post-mining land uses of industrial and commercial, recreation, and residential. <br />Carbon Junction Mine Page 2 <br />CORM5 September 15, 2010 and October 6, 2010 Inspection Responses
