6.0 EXHIBIT D — MINING PLAN <br /> This exhibit provides the information required by Section 6.4.4 of the Rules and <br /> Regulations. <br /> 6.1 Mining Methods and Surface Disturbance <br /> Section 6.1 provides the information required in Sub-section 6.4.4(a) Rules and <br /> Regulations. <br /> The entire site consists of 114.25 acres. There are approximately 76 acres that LRM will <br /> utilize for mining. Approximately 38 acres of the site will consist of boundary offsets, <br /> perimeter buffering the main access road, the Big Thompson River corridor, and <br /> stormwater management areas. <br /> 6.1.1 Site Preparation <br /> The site will first be cleared of unneeded existing structures(old fencing and cattle chutes). <br /> The topsoil, if present,material will be stripped as each Cell is mined. Stripping will occur <br /> in phases or"strips" approximately 1/8th to 1/41h of the size of the Cell to expose the active <br /> mining area. The stripped material will be stockpiled adjacent to the active mining area. <br /> Scrapers, front-end loaders, excavators, and bulldozers may be used for stripping. Topsoil <br /> stockpiles, ditches and grading may be used to direct stormwater into the mining cells. <br /> Exhibit C shows the quantities of topsoil for each phase. A typical topsoil stockpile berm <br /> size will be 36 feet in width, 10 foot high, or 6.6 sq-yd per ft. The topsoil stockpiles will <br /> be stabilized, and erosion control devices will be installed. If the topsoil stockpiles will be <br /> in place for an extended amount of time it will be seeded to produce a vegetated cover. <br /> An access bridge across the Big Thompson River will require a 404 Permit to construct. <br /> As part of the 404 Permit the bridge will be installed and analyzed to certify that it does <br /> not create a rise in the floodway. Haul roads will be established and stabilized during site <br /> preparation. <br /> Loveland Ready-Mix,Concrete,Inc. 6 September 2021 <br /> 20210912_maucr_apphcalwn_lrm_du prt_6nal draft dcez T E L E S T <br />
