(Page 2) MINE ID # OR PROSPECTING ID # M-1979-010 INSPECTION DATE 9/26/05 INSPECTOR'S INITIALS ESC This was an inspection of the Avrey Construction Pit conducted by Erica Crosby of the Colorado Division of Minerals and Geology. Kayette Hutchison of ACA Products, Inc. was present during the inspection. The site is located 1 mile south of Buena Vista in Chaffee County, Colorado. The Avrey Construction Pit is a 112 sand and gravel operation, permitted for 108 acres. The 112 permit was issued on January 15, 1980 for 40 acres. In 1999 the permit was amended to add 68 acres to the permit area. The Division holds a reclamation bond in the amount of $108,000.00. The approved postmining land use is rangeland. A mine identification sign was observed at the entrance to the site. Permit boundary markers were noted on site. Mining was actively taking place during the inspection. Product stockpiles were noted in the bottom of the pit. Awash plant and settling ponds were noted. In 1999, Technical Revision 01 (TR-O1) was approved by the Division that outlined disposal of inert material in the pit in the form of broken concrete and small amounts of metal waste generated at the site. Topsoil and overburden piles were noted along the perimeter of the permit area. The piles contain little to no vegetation with the exception of annual weeds. The operator will need to stabilize the piles to prevent wind and water erosion. The operator will need seed the piles with the approved seed mixture. See page 3 for further detail. The operator discussed expanding the mining area to the north. Currently it is an open field adjacent to the pit and immediately south of a residential area. Such expansion would require an amendment to the permit.
