M;S-349 <br />Notice of "Intent to Backfil] With Inert Material" <br />Rule 3.1.5(9) <br />Dear Mr. Squire: <br />PHONE (970) 8253489 <br />OR (970) 6251464 <br />(970)9639070 <br />FAX (970) 963.0180 <br />~1 <br />As required by rule 3.1.5(9) "Construction Materials <br />Rules", Casey Concrete, acting as operator of the above <br />referenced Mine is submitting the following notice that <br />Casey Concrete will be backfilling with inert fill. <br />A) The approximate location of the proposed activity <br />takes place in the southwest corner of the pit. A <br />map enclosed and shown as Exhibit "A" is marked <br />accordingly. <br />B) The approximate volume of inert material to be <br />backfilled would be roughly stated at 1200-1500 <br />CY of material annually. <br />C) A signed affidavit certifS'ing that the material is <br />clean and inert is attached and marked Exhibit "C" <br />D) The approximate dates that the proposed backfilling <br />activity will occur, mirrors the current ready-mix & <br />pit operations and in al] likelihood commence <br />immediately and end at the time all operations cease. <br />E) A brief explanation of how the backfilled site will <br />result in a post mining configuration follows. As a <br />result of backfilling, the only change that is <br />forseen for post mining land use will be an increase, <br />to a small extent, of seeded pasture land with a <br />proportionate decrease in water surface area. <br />F) A genera] engineering plan stating how the material <br />will be placed and stabilized in a manner to avoid <br />unacceptable settling and voids is as stated. The <br />majority of all backfilling will be accomplished by a <br />rubber-tired front end loader and that itself will <br />result in sufficient compaction due to the transverse <br />
