Mining has been completed in all cells/phases of the Platte <br />Valley operation except the processing plant area and concrete batch plant site (CelUPhase 5). These <br />areas will continue to operate with material being conveyed from Aggregate Industries' adjacent <br />Wittenberg Lakes operation (Permit M-2004-051). It is anticipated that mining within Phase 5 areas will <br />not occur until all material from the Wittenberg site has been processed through the Platte Valley plant. <br />All sloping has been completed around the lake in the southern half of the site and the lake has filled with <br />groundwater. Phase 2, except for approximately 2 acres on the south end, and the groundwater lake <br />slopes were seeded above the anticipated final lake elevation in Spring 2006. It is anticipated that the <br />backfilled azea at the south end of Phase 2 will be seeded during the current permit year. Backfilling of <br />Phase 4 will continue throughout the life of the mine in accordance with the permit reclamation plan and <br />the import inert fill notice approved by the Division on November 15, 2005. <br />Backfilling and grading of slopes in Phase 3 is also projected for the current permit year. Phase 3, as well <br />as remaining fines and fresh water pond areas in Phase 1, will continue to fill with fines as material from <br />the Wittenberg operation is processed through the Platte Valley plant. <br />Very truly yours, <br />G ~- / <br />Connie Nickle Davis <br />Land Resources Assistant <br />Enclosures <br />cc: Aggregate Industries - WCR, Inc. -File #30.04.03 <br />Aggregate Industries <br />West Central Region, Inc. <br />7707 Cole Blvd., Suite 100 <br />Golden, CO 80407 <br />Telephone:303-985-7070 An Equal Opportunity Employer <br />
