This <br />material is being backfilled into a previously mined pit located in the NW %< of Section 15, TSN, <br />R69W, West of Wilson Avenue and North of the Big Thompson River. Prior to the date we <br />started accepting outside fill materials, this area was used for disposal of onsite waste materials <br />consisting of waste concrete that had cured for at least six weeks and non-marketable fine <br />materials. <br />The total volume of the pit area to be filled is approximately 160,000 c.y. We estimate that 70 <br />percent of this volume has been generated from onsite material and 30 percent from offsite <br />material. Backfilling of this azea with onsite waste began in about 1987 and at the request of <br />some of our customers we began accepting offsite inert waste materials about 1997. We <br />anticipate that this area will be backfilled and reclaimed by the end of 2007. Effective November <br />15, 2002 we quit accepting any offsite waste except for clean fill dirt. <br />The material is being placed in the pit area in layers with the waste concrete and concrete and <br />waste rock rubble being placed in the bottom 3 to 4 feet with a dozer that tracks over the material <br />for some compaction. This lower layer is being covered with 3 to 4 feet of clean dirt, clay, and <br />silty material that is being dozed over the bottom layer and track-compacted. _The final layer will <br />be 6" to 12" of topsoil that will be graded level and seeded with grass. The final elevation will <br />approximate the original ground elevation prior to mining. <br />The final land use for this azea will be hiking, fishing, and wildlife viewing, so some minimal <br />settlement will have no impact on the final use. <br />Very truly yours, <br />LOVELAND READY MIX CONCRETE, INC. <br />George Steven Fancher <br />Vice President <br />
