8 Financial Assurance, Land Use, and Institutional • <br />Controls <br />8.1 Financial Assurance <br />Financial assurance for closure and post-closure is already covered under the mining <br />permit on file with the Division of Reclamation, Mining and Safety (DRMG). The <br />DRMG permit requires that the site be reclaimed and have a vegetative cover. A bond <br />has been placed for the DRMG permit and will be maintained and in place until <br />reclamation is completed. A financial assurance mechanism meeting the requirements in <br />the Regulations Pertaining to Solid Waste Disposal Sites and Facilities (6 CCR 1007-2) is <br />not necessary and would be redundant to the DRMS bond. <br />8.2 Future Uses <br />The Site will likely be used for residential, commercial or industrial purposes following <br />closure. Future development will comply with section 3.6.1(A)(7) of the solid waste <br />regulations and uses will not adversely affect: <br />• the integrity of the cover, <br />• the effectiveness of drainage or erosion controls, <br />• slope stability, or <br />• groundwater monitoring systems. <br />CDPHE will be informed of any future development and review and approve any such <br />development that may adversely affect any of the above listed items. <br />8.3 Post Closure Financial Assurance <br />The post-closure financial assurance is covered under the DRMS bonding mechanism. <br />Post-closure covers the cost of maintenance and repair of the cover, the erosion control <br />system, nuisance control including regular groundwater monitoring, and the surface water <br />control system. <br />8.3.1 Period <br />The post-closure care period will be 5 years for nuisance control and for maintenance and <br />repair of (1) the cover, (2) the erosion control system and (3) the surface water control <br />system. The post-closure care period for maintenance of the groundwater monitoring <br />system will commence after the submittal of a closure certification report according to <br />the closure certification report as described in the CDPHE Solid Waste Regulations. The <br />post-closure care period may be shortened as approved by CDPHE and Adams County. <br />The inert nature of the fill does not require gas monitoring and there will not be gas <br />monitoring in the post-closure care period. <br />• <br />AFS Frei-Henderson Inert Fill Page 22 of 23 <br />MOLEN & ASSOCIATES, LLC
