(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1998-024 <br />INSPECTION DATE 6/1 /02 <br />INSPECTOR'S INITIALS GRM <br />This inspection was conducted as part of the normal monitoring program of the Colorado Division of Minerals and Geology. <br />The permit file was not available for review due to imaging in the Denver Office. This inspection is limited to a review of <br />compliance with the Construction Materials Rules and Regulations. Specific issues concerning Mine Plan, Reclamation <br />Compliance and adequate banding could not be addressed. The Hidden Valley Pit is located on top of a mesa, approximately <br />1 ~/a miles north of Dotsero, Colorado, just west of junction of Colorado River Road and The Dry Creek turn off. The operator's <br />representative Jason Burkey meet the inspector at the site. <br />The mine identification sign and affected area boundary markers are in place and in compliance with Rule 3.1.12. The sign <br />is located at the entrance to the site at the bottom of the hill. Permit boundaries were noted as t-posts along the south and <br />east borders back 10 feet from the mesa edge and a fence line along the north and south lines. (Photo 1) <br />Noxious and/or problematic weed infestation (knapweed and thistle) was observed within the affected area. The infestation, <br />if not controlled, will most likely hinder and/or delay successful reclamation of this site and Contribute to off-site spreading and <br />establishment of these weeds. A weed control plan developed in consultation with, and approved by, the appropriate local <br />weed Control authority must be submitted as a technical revision to this permit. Weed infestation is noted as a problem, with <br />the corrective action{s) and correction date specified on the last page of this report. Significant progress toward control of on- <br />site weeds must be demonstrated within three years to avoid potential Board action. <br />Topsoil and overburden are being used as a site barrier along the south and eastern edges. Rule 3.1.9 requires topsoil have: <br />"protection from erosion, remains free of any contamination by toxic or acid-forming material, and is in a usable condition for <br />reclamation:' Side slopes of the stockpiles were observed to be devoid of any erosion control measures. If the stockpiles are <br />to remain in place for longer than a year, vegetative cover such as a nurse or cover crop should be used. Staff recommends <br />using the same seed mix and application rates that will be used in final reclamation. (Photo #2 ) <br />Sloping and benching within the pit was stable. Highwalls were 10 to 15 feet in height and interior sloping was near 3h:iv. <br />Reject boulders have been stockpiled against highwa{Is and will be used in backfill operations. (Photo # 3, 4 ) <br />Several stockpiles of material were noted. The amount of materials on site was not estimated. (Photo #3, 5) <br />There is no observable impact to the hydrological balance by the mining operation.. No ground water is exposed and no <br />evidence of erosion or stormwater impact was noted that would effect surface waters in the area. <br />No other issues were noted. <br />Responses to this inspection report should be directed to Russ Means at the Division of Minerals and Geoiogy, Grand Junction <br />Field Office, 101 South 3rd Street, Room 301, Grand Junction, Colorado 81501, phone no. 970-241-1117. <br />I & E Contact Address cc: <br />NAME Jason Burkev <br />OPERATOR B&B Excavating.
