CO 80203 <br />FEB 0 6 2006 <br />Division of Minerals and Geology <br /> <br />AGGREGATE <br />INDUSTRIES <br />Re: Permit No. M-1992-069, 83`' Joint Venture -Annual Report, Map and Well Monitoring Data <br />Ladies and Gentlemen: <br />Enclosed is the annual report form together with a map and Check Number 88746 in the amount of <br />$688.00 for the above-referenced permit for permit year ending January 26, 2006. <br />Mining of this site was completed in 2003, and the aggregate processing plant and asphalt plant, located <br />in the eastern portion of the site (Phase 1) were removed. Material stockpiles and miscellaneous <br />equipment remain within the north-central azea of the project, while sales of processed material and the <br />reclamation phase of mining activity continues. <br />Activity during the report year ending January 26, 2006 included installation by the City of Greeley of a <br />storm water culvert into the pit on the south boundary and a concrete weir overflow structure on the north <br />boundary of Phase 1 in accordance with Revision No. TR-5 of the permit. Reclamation of these disturbed <br />areas, including sloping and seeding, were completed. <br />Reclamation activity completed in 2005 included reseedmg of the upland boundaries of Phase 2 and <br />seeding of wetland benches adjacent to the north boundary of Phase 2 to an upland seed mix for <br />stabilization until groundwater rebounds sufficiently to support wetland vegetation. Dewatering of Phase <br />2 ceased in 2004, allowing the Phase 2 pond azea to begin filling with groundwater; however groundwater <br />has not fully rebounded due to continued dewatering in Phase 1 and dewatering at an adjacent mining <br />operation to the north. <br />Dewatering may resume briefly in 2006 in Phase 2 while inert fill material imported to the site is <br />backfilled in the southeastern pond area in accordance with the notice provided to the Division August 2, <br />Aggregate Industries <br />West Central Region, Inc. <br />7707 Cole Blvd., Suite 700 <br />Golden, CO 80407 <br />Telephone:303-985-7070 An Equal Opportunity Employer <br />
