The inspection was conducted on September 25, 2023. Clayton <br />Wein of the Division completed the inspection. Elk Ridge Mining and Reclamation (ERMR) <br />was represented during the inspection by Mindy Sickles. The weather was clear with a <br />temperature of 75 degrees F. The ground conditions were dry. <br /> <br />No maintenance items were identified during this inspection. <br /> <br />AVAILABILITY OF RECORDS – Rule 5.02.4(1): <br /> The records for the New Horizon North Mine are located at the Mine Office in Nucla, CO. The records <br />were well kept and up to date. The operator was working on replacing the Insurance Certificate for the mine when <br />the inspection was concluding. Please see the Availability of Records Form attached to the end of this report for <br />more details. <br /> <br />BACKFILL and GRADING – Rule 4.14 <br />Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); <br />Steep Slopes 4.14.2, 4.27; Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br /> Reclamation work on Pond 001, Pond 002 and the associated drainage ditches was completed prior to the <br />inspection. Pond 001 was reduced in size to a small stock pond by the landowner’s request. The area around the <br />pond was graded to slope gently. The reclaimed area surrounding the pond was stable with no concerns of <br />erosional features. The stock pond was holding a small amount of water in it during the inspection (Photo 1). The <br />ditch north of pond one was also reclaimed. The reclaimed area was gently sloping and returned to approximate <br />original contour (Photo 2). The area was stable and there were no erosional features identified. The remaining <br />northern ditch follows the highpoint to where pond 002 used to be located. The reclaimed ditch was stable with <br />gently sloping contours (Photo 3). The area was stable with no erosion. The reclaimed pond 002 area was also <br />stable with no indications of erosion. The Bench 1 Stockpile and Mixed Topsoil Stockpile 1 were utilized in the <br />reclamation work. The topography of the reclaimed pond and stockpile footprints was stable (Photo 4). There <br />were no indications of erosion. The area was gently sloping and resembled the approximate original contour. The
