Green/Croissant, M-2001-022 <br />Imported Material and Related Activity <br />March 14, 2005 <br />Page 2 <br />Iri accordance with the requirements of Rule 3.1.5, the following is provided for your <br />information and review. Each letter corresponds to the equivalent subpart of Rule 3.1.5 <br />(9)• <br />(a) Description of the Approximate Location of the Proposed Activity. <br />Pit run will be generated at the proposed Walters/Bokelman sand and gravel mine, <br />approximately Y< mile to the northwest of the Green/Croissant site. Fines will be <br />generated within the existing, approved processing and plant area on the <br />Green/Croissant site. Fines will then be distributed as backfill in Cell 2 during <br />reclamation of mine cells. A location map is attached. <br />(ti) The Approximate Volume of Inert Material to be Backfilled <br />The process of crushing will yield a typical 3 to 5 percent, but possibly up to 10 percent, <br />by weight, of non-marketable fines. This yield is confirmed by current operations at <br />Green/Croissant, in essentially the same deposit. Based on estimates of the reserve at <br />Walters/Bokelman, a maximum of approximately 150,000 to 250,000 tons of fines may <br />be generated at Green/Croissant as a result of this proposal. <br />This amount of fine material can be incorporated in the reclamation for Green/Croissant <br />-especially given the potential need for shallow shorelines and wetland mitigation - <br />without modifying the current 112 Reclamation Plan. <br />Based on the standard density of crusher fines, it is estimated that 165,000 cubic yards <br />of backfill material (but up to a maximum of 320,000 if fine yields are higher for the new <br />pit) will be generated by processing pit run from the Walters/Bokelman area. This <br />volume may be lower if production and import from Walters/Bokelman is lower than <br />anticipated, if fine yields are lower than anticipated, if fines are used for backfill at <br />Walters/Bokelman, or in the event of other circumstances. <br />i <br />(c) A Signed Affidavit Certifying that the Material is Clean and Inert. <br />An affidavit signed by an officer of Loveland Ready Mix Concrete, Inc. is attached. <br />(d) The Approximate Dates the Proposed Activity Will Commence and End. <br />The import of material from Walters/Bokelman will commence once the DMG and <br />Larimer County permitting process, stripping, and other start-up at that site is complete. <br />This may occur as soon as 2006. <br />Based on the anticipated life of mine at Walters/Bokelman, the use of off-site fill will <br />continue through the final phase of reclamation at the Green/Croissant site, until 2025 to <br />2030 according to current estimates. <br />
