This was a routine monitoring inspection conducted by Tyler O'Donnell of the Division of Reclamation, Mining <br />and Safety (Division). Allen Watts, the mine operator's representative was present during the inspection. The <br />Murdock Gravel Pit is located approximately 7 miles southwest of Sheridan Lake, Colorado. The Murdock <br />Gravel Pit is permitted as a sand and gravel pit. The approved permit area is 9.2 acres. The approved post - <br />mining land use is rangeland. <br />The sky was clear and the ground was dry, with the exception of a few snow patches. No mining equipment <br />was operating or present at the time of the inspection. The last annual report indicates the site has not been <br />operational since May 2012. The operator's representative explained to the inspector that this site is only <br />used occasionally for localized road repairs. The current disturbance appeared to be approximately 9 acres. <br />No problems or violations were observed during the inspection. <br />Backfilling and Grading: <br />No backfilling and grading has been conducted on the site. <br />Hydrologic Balance: <br />The bottom of the pit was dry. There was no evidence of excessive erosion. There appeared to be no <br />significant impacts to the prevailing hydrologic balance. <br />Gen. Compliance With Mine Plan: <br />The current pit had a highwall that was approximately 15 ft high. The current pit is daylighting to the eastern <br />portion of the permit area. All mining activity appeared to be within the approved permit boundary. <br />Roads: <br />The access road was in good condition. <br />Red Plan /Comp: <br />This site has not yet been reclaimed. <br />OBSERVATIONS <br />PERMIT #: M- 1983 -112 <br />INSPECTOR'S INITIALS: TOD <br />INSPECTION DATE: March 6, 2013 <br />Revegetation: <br />There were a few annual weeds, but they did not appear as an infestation or a problem. There was good plant <br />growth on the topsoil stockpiles and good vegetation growth elsewhere in the disturbed area. The plant <br />growth within the disturbed area appeared to be volunteer vegetation. <br />Erosion /Sedimentation: <br />There was no evidence of excessive erosion (rills, gullies, or sediment fans). <br />Signs and Markers: <br />A mine I.D. sign was located at the entrance to the mine site. The permitted area of the mine site is round and <br />therefore the permit boundary is difficult to locate. There were boundary markers on the northeast and the <br />northwest side of the pit. The rest of the permit boundary was delineated by a large berm which <br />encompasses the entire site. <br />Page 2 of 4 <br />
