(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1999-021 <br />INSPECTION DATE 03/07/06 <br />INSPECTOR'S INITIALS ESC <br />This was a routine inspection of the Stegner Farms Pit conducted by Erica Crosby of the <br />Division of Minerals and Geology. Connie Davis of Aggregate industries- WCR, Inc. was <br />present during the inspection. <br />The Stegner Farms Pit is located 1/2 mile southeast of LaPorte in Larimer County, <br />Colorado. An 112c Mining and Reclamation Permit was issued on March 6, 2000 for a permit <br />area of 80 acres in size. The postmining land use is developed water resources and the <br />Division holds a financial warranty in the amount of $273,400.00. <br />No mining was taking place during the inspection. According to the operator, mining <br />temporarily ceased in 2003. Site maintenance has occurred on site including installation <br />of the perimeter drain system around the slurry wall, reshaping of the overburden piles <br />and weed control measures. The remaining area to be mine is in the northwest corner of <br />the site, and contains approximately 200,000 tons of material. Aggregate Industries <br />anticipates contracting out the remainder of the mining this year due to the lack of <br />company presence in the Fort Collins area. If Aggregate Industries is unable to secure a <br />contractor or does not anticipate mining this year, the site will need to be put in <br />temporary cessation (TC) status. See Rule 1.13 of the Construction Materials Rules and <br />Regulations for detail on the TC requirements. <br />On November 1, 2004, the Division approved TR-04 that describes the perimeter drain <br />designs around the north and west boundaries of the slurry wall. The drain design includes <br />eight-inch perforated pipe to be used throughout the groundwater interception areas, <br />transitioning to an 8-inch solid pipe. The a-inch pipe is transitioned to a 6-inch <br />perforated pipe in the downgradient re-charge area. Pipes are covered with gravel wrapped <br />in geotextile filter fabric. Aggregate industries is committed to monitoring the existing <br />wells until reclamation is complete and the site is released from reclamation liability. <br />According to the operator, the drain was completed in the fall of 2005. The operator will <br />need to revegetate the areas recently disturbed with the installation of the drain to <br />prevent the encroachment of weeds. <br />I & 8 Coatact Addrase <br />NAME Connie Davie <br />^ CE <br />^ BL <br />OPERATOR Aggregate Industries-WCR, Inc. ^ FS <br />STREET 1707 Cole Blvd., Suite 100 ^ HW <br />CITY/STATE/ZIP Golden, CO 80401 ^ HMWMD (CH) <br /> ^ SE <br /> ^ WQCD (CH) <br />Cc: Carl Mount; DMG <br />
