DATE: Apri129, 2002 <br />TO: Gregg Squire <br />FROM: Allen Sorenson <br />RE: ~ Slurry Wall Installation for a Post Mining Land Use of Developed Water Resources, <br />City of Greeley, 25`~ Avenue Site, File No. M-2002-002 <br />The Applicant' proposal to install a slates that the installation will meet the performance <br />criteria established by the State Engineer for sealed reservoirs. The Division of Minerals and Geology <br />(DMG), in consultation with the Office of the State Engineer and the Colorado Rock Products <br />Association has developed guidelines and policies for reclamation plans that include the sealing of <br />gravel pits for use as water storage reservoirs. A copy of DMG's sealed reservoir guidance document <br />is attached to this memorandum. The DMG guidance provides two options for reclamation of gravel <br />pits as sealed reservoirs. One option is for the Applicant to provide a basic description of the reservoir <br />sealing plan with the provision of a reclamation bond that would cover the cost of 100 percent of <br />reservoir sealing costs in the event or permit revocation and bond forfeiture. The second option allows <br />for the provision of a reclamation bond that is equal to the cost of reinstalling 20 percent of previously <br />constructed reservoir liner if the DMG is provided with designs plans, technical specifications, and <br />quality assurance testing protocols as an enforceable component of the mined land reclamation plan. <br />The situation with a municipality such as the City of Greeley being the Applicant is unique in that the <br />regulations for mined land reclamation permits exempt Cities from financial bonding requirements. <br />However, Cities are not exempt from the requirements to fully describe how reclamation measures will <br />be implemented. As a result, the City of Greeley as an Applicant is not eligible for the 20 percent <br />bonding option with provision of minimal design information, and by default must provide design <br />details, technical specifications, and quality assurance (QA) procedures for the DMG's review prior to <br />approval of the reclamation permit application. <br />In order for the DMG to approve the City's application for the 25`h Avenue Site, design information, <br />specifications, and QA must be incorporated as enforceable component of the permit application. The <br />essential elements required for submittal are described in the attached DMG guidance/policy <br />document. It is the DMG's understanding that a contractor is standing by to begin construction of the <br />slurry wall at the 25`~ Avenue Site. If a contract has been let for this project, it is likely that all of the <br />plans, specifications, and QA information that will be required by the DMG have already been <br />generated. <br />attachment(s) <br />cc: Carl Mount, DMG (via electronic transmission) <br />m:~My Dacumen[s~25'" Avenuc.doc <br />
