PERMIT#: M-1980-047 <br /> INSPECTOR'S INITIALS:THM <br /> INSPECTION DATE:July 14,2015 <br /> OBSERVATIONS <br /> This inspection was conducted as part of the normal monitoring program established by the Colorado Division <br /> of Reclamation, Mining and Safety(DRMS). <br /> This was a complete inspection to observe all components of the mining operation. The Colony Shale Oil <br /> Project consists of a total permit acreage of 5,712.05 acres with a maximum allowed disturbance of 527 acres. <br /> Tom Adams, Glen Murdock and Erin Leftwich, all three representing ExxonMobil, were present during the <br /> inspection. <br /> The first area inspected was the mine bench and mine drifts (Area 6 on the enclosed map). The mine drifts were <br /> both sealed with concrete with steel doors. The mine water was observed draining from both mine entrances <br /> via a drainage ditch that flows from the north to the south. Evidence of mine roof stability work was observed <br /> in the form of an epoxy adhesive which was pressure injected into small boreholes. The mine bench was void <br /> of any structures or facilities and was free of any trash or unnecessary debris. <br /> The next area observed was the Davis Gulch cofferdam / sediment pond (Area 9 on the enclosed map). This <br /> area was adequately vegetated and there was minimal evidence of any prior disturbance observed. <br /> Area 17A, a spent shale fill area, was observed and was void of any significant vegetation. The area was free of <br /> any unnecessary debris. <br /> Areas 18E, 18F and 18G were observed. These areas were where the process plant and secondary crusher were <br /> going to be located. The areas were graded and appeared to be stable due to the primarily flat grade and the <br /> adequate volunteer vegetation present. <br /> Area 18A is a flat area that has adequate interim vegetation. A power line was present. The purpose of area <br /> 18A was not determined during the inspection. It is speculated that it might be an overburden storage area. <br /> The ESR experimental plots were visited during the inspection. Facilities included several small buildings, <br /> weather monitoring stations and vegetative test plots along with associated support facilities for each plot. <br /> Area 16A is located north of a valley that's proposed use was a shale disposal area. 16A is flat graded and also <br /> had adequate interim vegetation. <br /> Topsoil areas 12 and 14 were both observed and appeared to have adequate interim vegetation. It is speculated <br /> that the topsoil stockpile depth of area 12 may be too great of a depth for preservation of desirable topsoil <br /> characteristics. Typically topsoil stockpiles greater than 10 feet in depth inhibit the preservation of beneficial <br /> soil microorginisms. Also, the length of time the topsoil has been stockpiled most likely has had a negative <br /> impact on the topsoil's quality. <br /> The lower portion of area 10A adjacent to the road appeared to have adequate vegetation and could likely be <br /> released from the permit area with no additional required reclamation work. <br /> Area 8B was a flat area that was graveled and had a concrete pad where a building was located but has since <br /> been removed. <br /> The final spot visited during the inspection was the Middle Fork Reservoir and Middle Fork Dam. The dam is <br /> constructed out of rolled compacted concrete. The condition of the dam appears to be good and is inspected <br /> Page 2 of 9 <br />
