Box 299 -Loveland, Colorado 80539-0299 December 6, 2002 Colorado Division of Minerals & Geology Department of Natural Resources 1313 Sherman Street, Room 215 '~ Denver, CO 80203 ~` ATTN: Erica Crosby Dear Ms. Crosby: Tn accordance with Rule 3.1.5(9) Loveland Ready Mix Concrete, Inc. hereby notifies you that we are accepting inert structural fill materials generated outside the approved permit area. This material is being backfilled into a previously mined pit located in tbe NW '/. of Section 15, TSN, R69W, West of Wilson Avenue and North of the Big Thompson River. Prior to the date we started accepting outside 5ll materials, this area was used for disposal of onsite waste materials consisting of waste concrete that had cured for at least six weeks and non-marketable fine materials. The total volume of the pit area to be filled is approximately 160,000 c.y. We estimate that 70 percent of this volume has been generated from onsite material and 30 percent from offsite material. Backfilling of this area with onsite waste began in about 1987 and at the request of some of our customers we began accepting offsite inert waste materials about 1997. We amicipate that this area will be bacld'illed and reclaimed by the end of 2007. Effective November I5, 2002 we quit accepting any offsite waste except for clean fill dirt. The material is being placed in the pit area in layers with the waste concrete and concrete and waste rock rubble being placed in the bottom 3 to 4 feet with a dozer that tracks over the material for some compaction. This lower layer is being covered with 3 to 4 feet of clean dirt, clay, and silty material that is being dozed over the bottom layer and tracktompacted. The final layer will be 6" to 12" of topsoil that will be graded level and seeded with grass. The final elevation will approximate the original ground elevation prior to mining. The final land use for this area will be hiking, fishing, and wildlife viewing, so some minimal settlement will have no impact on the final use. Very truly yours, LOVELAND READY MIX CONCRETE, INC.
