OBSERVATIONS <br />PERMIT #: M-2011-049 <br />INSPECTOR'S INITIALS: ECS <br />INSPECTION DATE: December 13, 2011 <br />This was a "pre -op" inspection for a new 112c application - the Treiber Lakes site. The inspection was <br />conducted by Eric Scott of DRMS. DRMS met with David Jordan of Lafarge and consultant for City of <br />Greeley /Tri -Lakes Water Bill Schenderlein on -site at approximately 0930. The site entrance is located on the <br />west side of Taft Hill Road north of Ft Collins, near the west side of the Lafarge Home Office Pit site (M1977- <br />439). The permit applied for notice was present at the entrance to the Lafarge site, but needs to be placed at the <br />entrance to the new permit area as noted on the first page of this report. This will also apply to the mine <br />identification sign when the permit is approved. <br />The proposed 94 acre Treiber Lakes permit was previously part of the 601 acre Lafarge Home Office Pit. This <br />area is being "re- permitted" by the City of Greeley so that it can be reclaimed by them as developed water <br />storage. When the new Treiber Lakes permit is approved, that area will be released from the existing Lafarge <br />Home Office Pit permit. The Lafarge plant area and scale house is located immediately adjacent to the new <br />Treiber Lakes site, therefore the new permit boundary between these sites will need to be clearly and <br />permanently marked to prevent any "off site impacts" to the new permit area or between the two sites. <br />Mining in the new Treiber Lakes permit area was previously completed by Lafarge, who still operate the <br />remaining permitted area of the Home Office Pit. Reclamation for the new permit will include the installation <br />of a slurry wall, some re- sloping of the existing lake shore areas, and revegetation of disturbed areas. When the <br />revised reclamation plan has been completed by the City of Greeley, and the slurry wall has been approved by <br />the SEO, DRMS will release the permit on this site. <br />No other issues or problems were noted during the inspection. This concluded the inspection and DRMS left <br />the site at approximately 1040. <br />Page 2 of 3 <br />
