Because Lafazge proposes <br />to use backfill material generated outside the permit azea, Lafazge will be subject to the <br />provisions of Rule 3.1.5, "Reclamation Measures- Materials Handling", that pertain to <br />backfilling. In accordance with Rule 3.1.5(9)(c), Lafarge must provide a signed affadavit <br />certifying that the material is clean and inert, as defined in Rule 1.1(20). <br />The decision date for this amendment is April 12, 2007. If you are unable to adequately <br />address this item it will be your responsibility to request an extension of the decision <br />date. If it has not been adequately addressed and no extension has been requested, the <br />amendment will be denied. <br />If you have any questions you may cal] me at 303-866-3927. <br />Si cerely, <br />~~~~~~ <br />David A.
