LAFARGE <br />NORTH AMERICA <br />Construction Materials <br />Apri126, 2004 <br />Ms. Margaret Langworthy <br />Department of the Army <br />Corps of Engineers, Omaha District <br />Denver Regulatory Office <br />9307 South Wadsworth Blvd <br />Littleton, CO 80128-6901 <br />Dear Margaret, <br />RECEil~E~ <br />APR 2 8 2004 "~ <br />Division of Minerals & CeoleBY <br />This letter follows-up on our telephone conversation on April 19, 2004, regarding the reclamation <br />requirements of the Colorado Mined Land Reclamation Board (MLRB). Based on our conversation, it <br />appears that the Corps was uncertain regarding Lafarge's existing reclamation plan for the Nelson Pit <br />(M-1974-070, as approved by the MLRB) and its relationship to the proposed Section 404 permit <br />mitigation plan for the Nelson property. <br />The Colorado Mined Land Reclamation Act for the Extraction of Construction Materials specifies [he <br />standards that apply to the mining and reclamation of sand and gravel extraction sites. The goal of the <br />statute and the function of the MLRB is to ensure land disturbed by mining is returned, through <br />reclamation, to some beneficial post-mining land use. The Division of Minerals and Geology (DMG) is <br />the administrative and technical staff to the MLRB. <br />The State's mined land reclamation program does not dictate what post-mining land uses should be <br />created (e.g., agricultural, recreational, residential, industrial, wildlife, etc.). That is a decision lefr to the <br />permittee (i.e., the operator) and the landowner. Once these two parties agree upon apost-mining land <br />use, the reclamation plan, which is a component of the mined land permit, ensures that mined azeas will <br />be reclaimed to minimum, enforceable standards designed to provide for the end-use. What is essential <br />to understand is that neither the MLRB nor the DMG mandates what post-mining land use should <br />prevail. That decision is left solely to the operator and the landowner. <br />For example, when an operator applies for an MLRB permit to conduct mining operations, the operator <br />must specify on the application form the post-mining land use (see enclosed Reclamation Permit <br />Application, Item 10). The written text of the permit application must explain in detail how the operator <br />plans to create the end-use. If the applicant proposes to reclaim the area as rangeland, the operator would <br />describe the material to be used for backfill, the minimum reclaimed slopes, and the proposed seed mix. <br />The DMG must then ensure the proposed reclamation plan meets the minimum standards (minimum <br />slopes, adequately seeded, weed management, etc.) and that the plan is adequately bonded prior to <br />issuing the permit. The amount of the bond corresponds to the cost the applicant/operator will incur to <br />complete the approved reclamation plan. The bond is posted as a means of securing the reclamation and <br />it is released to the operator upon determination by the DMG that the reclamation has been completed <br />successfully. <br />Often times over the life of a project the reclamation plan must be modified after the permit is issued. A <br />change in the reclamation plan can be necessitated by several situations, including change in land <br />ownership, change in the anticipated extent of the deposit to be mined, or simply a change in mazket <br />~'~ R- c c ~ <br />~c ~a~s. <br />/M- lq?~-(-a~ 0 <br />LAFARGE NORTH AMERICA INC. -Lafarge Construction Materials <br />1400 West 64`^ Avenue, Denver, Colorado 80221 <br />Telephone: (303) 657-4000 Facsimile: (303) 657-4037 <br />
