(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1977-348 <br />INSPECTION DATE: 6/19/09 INSPECTOR'S INITIALS: ECS_ <br />OBSERVATIONS <br />This was a routine monitoring inspection for an active 112c limestone operation conducted by Eric Scott of <br />DRMS for the Boettcher Quarry site. DRMS met with site operator Michael Toelle on site at approximately <br />0930 and toured the site with him. <br />The required site entrance postings and site boundary markers need to be refreshed and/or replaced as no site <br />entrance sign was present. <br />Mining and reclamation activities have been completed at the site, and the revegetation is coming in well at this <br />time. Weed control efforts will need to be maintained to keep noxious species from establishing in reclaimed <br />areas while the grasses continue to come in - especially in the more recently seeded areas. <br />Water has collected in the bottoms of several of the reclaimed quarry areas. The State Engineer requires that <br />this water be properly permitted or decreed, or that provisions are made to release captured water within 72 <br />hours of impoundment. Holcim must contact the State Engineer's office to determine what options are <br />available to deal with the water retained in these areas, and provide DRMS with the appropriate documentation <br />of the resolution of this issue before the site can be released. <br />Water quality data collected from the monitoring wells associated with the CKD disposal cell must also be <br />submitted to DRMS for review to determine if additional actions are needed for the protection of groundwater <br />at the site, or if monitoring activities can be discontinued. <br />With the exceptions of the issues noted above, the overall reclamation at the site has been very well done and is <br />progressing well at this time. It is possible that the northern area of the site (where vegetation has been in place <br />longest, and no water has been impounded) may be eligible for release near the end of this season. Site <br />boundary markers should be established in reclaimed areas prior to release, so that it can be easily determined <br />what areas subject to post law reclamation requirements. <br />I & E Contact Address <br />Michael Toelle <br />Holcim Inc. <br />3500 Highway 120 <br />Florence, CO 81226
