• (Page 21 MINE ID # OR PROSPECTING ID # INSPECTION DATE 1 /24/96 M~4-155 • INSPECTOR'S INITIALS WHE OBSERVATIONS This partial inspection was conducted by Wally Erickson from the DMG field office in Durango. Mr. Tim Huskey, Dolores County Road Department, accompanied the DMG inspector through out this inspection. The mine site is located approximately 4 miles SW of Dove Creek, at the NW corner of the intersection of County Roads G & L. The original 110 permit, issued on 9/27184, was converted to a 112 permit on 10/7/94. Currently, the Bartley Gravel Pit is approved for 77.3 acres affected area. Mine operations were dormant during the time of this inspection. Mining equipment located on site was limited to two dozers. Fuels tanks, lubricants, and chemicals were not located on site. Approximately 3" snow cover existed with minor drifting in wind sheltered areas. Mine identification sign and affected area perimeter markers were in compliance with Rule 3.1.12. Mine identification sign was clearly visible at the old east entrance to the mine site and should be moved to the south entrance currently being utilized. Affected area perimeter markers consist of an abandoned fence line along the north and west boundaries and CR-G and CR-L for the east and south boundaries. Mining related disturbances were contain within the approved area. Mining activities have avoided the buried gas pipeline which extends from the NE corner of the permit area to the south-central border. Location of the pipeline was well marked. The mine identification sign was posted beside a utility pole, located on the east side of the permit area. Mitwrq operations had excavated material surrounding the utility pole resulting in the pole setting on an Island of material. Side slopes of the "island" were steeper than 3H:1 V and did not appear stable. Rule 6.4.19 states that where the operetion will adversely affect the stability of any significant, valuahle or permanent man-made structure located within 200' of affected land, the applicant may either: lal provide a notarized agreement between the applicant and the person(s) having an interest in the structure, that the applicant is to provide compensatbn for any damage to the structure; or 161 when such an agreement care not be reached, the applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining operation. Please provide the information required by Rule 6.4.19 for the buried gas pipeline and the utility poles located on the west side of CR-G and on the north side of CR-L. Mining has progressed from the SE corner of the permit area, across the pipeline, and is currently located in the western 1 /3 of the permit area. Approximately 1 /3 of the permit area appears to have been reclaimed and revegetated with another 1 /4 having achieved final grading requirements. Reclamation appeared to be concurrent with advance of mining activity. At the current pit location, topsoil was stockpiled along the north pit boundary, subsoil was stockpiled along the east and west pit boundaries, material stockpile existed at the south pit boundary. Topsoil stockpile appeared to have been recently constructed and did not exhibit evidence of erosion, instability or contamination. Topsoil stockpiles that will remain for periods of 1 year or longer, require a protective vegetative cover, as required by Rules 3.1.911) and 131. A small pit was located within the permit area, east of the active operation. The operator indicated that the small pit was a clay deposit being excavated to mix with the sandstone gravel to bind the material. Clay pit area was heavily infested with weeds. Weeds were not observed at the active pi[ area but were abundant through out the reclaimed portion of the permit area. The operator needs to perform weed control measures on the affected areas of the operation. Rule 3.1.10(6) states that weed control shall be employed for all prohibited noxious weed species, and whenever invasion of a reclaimed area by other weed species seriously threatens the continued development of the desired vegetation. Weed control methods shall also be used whenever the kthabihtion of the raeldmed vea by weeds threatens further spread of serious weed pests to nearby areas. A list of noxious end problem wands and eontrd techniques for tMse species can be obtained from the County Extension Sarv(cs, the Coumy Wand Control Disttiet OHlee, or tM load office of tfre Shc Conssmtbn Service.
