(Page 2) MINE ID # OR PROSPECTING ID #: M-1981-006 INSPECTION DATE: 7-7-04 INSPECTOR'S INITIALS GRM OBSERVATIONS This inspection was conducted as part of the normal monitoring program established by the Colorado Division of Minerals and Geology. The West Rifle Pit is located just south of Highway 6 and the Rifle By-pass in Rifle, Colorado. The Pit is actually 2 permits, there is a l l lc pemut (M-95-018) and the greater majority being under this 112c permit, M-1981-006. This Report focuses on the 112c permit of approximately 22 acres. Mr. Gil Lee, representative for Central Aggregates, accompanied the inspector on this inspection. Signage for the site is posted at the entrance to the area a1 the railroad crossing. Site boundaries aze clearly delineated by berms, fence lines and the river. The mine identification sign and affected area boundary mazkers are in place and in compliance with Rule 3.1.12. Of the 22 acres approximately 10 is a lake created by the 112c excavation. Vegetation along the banks includes servicebeny, willows, and several species of natural grasses. The only visible issue noted for this and the 111 are infestations of noxious weeds knapweed, white-top, thistle and tamarisk along access roads. The fact that the infestations aze primarily contained to the access roads is an indication of success of the rest of the vegetation along the banks of the pond. The infestation, ifnot controlled, will most likelyhinderand/or delay successful reclamation of this site and contribute tooff--site spreading and establishment of these weeds. A weed control plan develoned in consultation with, and annroved bx the anoropriate local weed control authority must be submitted as a technical revision to this Hermit. The weed infestation is not noted as a problem at this time, however it is being noted as an issue of concern. The issue must be addressed within 60 days to prevent the weed issue from becoming a noted problem or possible violation of the approved permit. Please review the last page of this report for a specific due date for the submission of a Weed Control Plan. Significant progress toward control of on-site weeds must be demonstrated within three years to avoid potential Board action. A copy ofthis report will be sent to the appropriate weed control authority for this area: Garf eld County Vegetation Control, Steve Anthony, (970)-625-8601. All sloping of banks in this area appear to be 3:1 or better as required. No erosion or other storm water issues are noted at this time. No off-site damage was observed. Fuels and other hazardous materials are all stored correctly. A concrete secondary containment structure is used and appears adequate to contain the contents of the largest tank within it. Some older fuel stands were observed, but they are empty and clean. No evidence of spills or other contamination is noted. The permit records held by the Division for this site are better than the 111. The Reclamation Plan and other aspects are typical of early 1980 permits. Besides the weed control issue, staff requests update documentation on efforts to secure a water aug<nentationplan. Documentation of continued progress towazds the fmal water plan helps keep the exposure of water as an issue and nothing more. The permitee appeazs to be following both the mining and reclamation plans as submitted. . Finally, it appears that fill material has been imported to the site for use as structural fill. DMG records do not indicate that the notice specified in Rule 3.1.5 (9) has been submitted for this backfill importation and placement. Please submit this notice by the correction date specified in the last section of this report. No other problems or issues noted at this time.
