(:q )Q (IP3 ) ALtBffs <br />June 25, 2018 <br />Colorado Division of Reclamation, Mining and Safety RECEIVED <br />Attention: Peter Hays <br />1313 Sherman Street, Room 215 JUN 2 2018 <br />Denver, CO 80203 <br />DIVISION OF RECLAMATION <br />MININrD SAFETY <br />RE: Inspection Report Cottonwood (M-2004-061) Corrective Action, Abatement Summary <br />Dear Mr. Hays, <br />This letter is in response to your inspection report dated May 25th, 2018 pertaining to the noted <br />problems contained within the report. One of the noted problems was for the PVC Pipe, which was <br />observed near the southwest corner of the site during the inspection. After further investigation, we have <br />concluded this pipe was installed by the predecessor for proper drainage of a natural spring so that the <br />water does not become impounded within the bermed area of the pit. Furthermore, the water is not <br />discharging offsite as evident during the inspection the water after its initial discharge from the PVC <br />pipe percolates back into the surface approximately 80 feet south of the protruding pipe. <br />The second problem indicated in the inspection report is signs & markers for the mining <br />boundary pertaining to the haul road in question. A survey of the boundary was staked and flagged (see <br />attached photos) as indicated in the photos the haul road is well within the boundary of the markers. <br />There is speculation as to the fill from the road that created a berm between the road and the boundary <br />Iine, whereas the toe of this material may be in contact with the boundary line. Staff has made note of <br />this observation and have determined to remove any material that may be in close proximity to the <br />boundary line and match to the existing surface contours, as well as seed any areas that are impacted <br />from this correction. <br />Please feel free to give me a call if you have any questions. <br />Kindest Regards, <br />Jon Mueller <br />Environmental Compliance Coordinator <br />Kilgore Companies - Colorado Companies <br />556 Struthers Avenue — Grand Junction, CO 81501 <br />Main: 970.242.5370 - Direct: 970.255.2098 - Mob: 970.261.5782 <br />
