EXHIBIT D MINING PLAN <br /> 1. General Mining Plan <br /> All areas to be mined are currently considered high and dry. The deposit will be mined to a <br /> maximum depth of 50 feet. It is anticipated that groundwater will be encountered during mining <br /> operations at a depth of approximately 30 feet at which point mining will cease in that pit. No <br /> initial attempts will be made to dewater the pit either during mining or post-mining. Mining <br /> below groundwater will not be attempted until an augmentation plan or substitute water supply <br /> plan is in place for related depletions. Until such time, mining will stay entirely above the <br /> groundwater table by at least two feet. In the event groundwater is encountered, exposed <br /> groundwater will be backfilled to a depth of two feet and this will be the new pit floor elevation <br /> Excavation will create an open pit using standard mining equipment such as front end loader, <br /> dozer, dredge, and excavator. No blasting will occur. <br /> Processing will take place on site and includes crushing and screening to size; reject material will <br /> be used for final reclamation. Processing will use mobile equipment deployed to the site on an <br /> `as-needed' basis. An asphalt plant and a concrete batch plant will be located on site at a location <br /> west/northwest of Pit 1, see Map C-2. These will ultimately be removed after cessation of mining <br /> activities. <br /> Mining will occur to the final reclamation slopes as shown on Map C-2. Pit slopes will be <br /> constructed at a 3H:1V slope to the pit floor. The maximum depth of mining will be 50 feet. <br /> Reclamation will follow in a timely manner once an area is deemed mined out. Seeding and final <br /> grading will facilitate the final reclamation use of rangeland and water storage the landowner has <br /> prescribed. <br /> 1_1 Rule 6.4.4 <br /> The following will address the items listed under Rule 6.4.4 Exhibit D in order of appearance. <br /> Please see Mining Plan Map C-2 for more information and correlations. <br /> Like similar open pit sand and gravel operations, this pit will be stripped of the available topsoil <br /> growth medium as indicated on the Soil Report by earthmoving scrapers and loaders. Topsoil <br /> will be stockpiled on site to the west of what will ultimately become Pit 1 (see Map C-2) and left <br /> Birdseye Pit (day;1 ewickj and lsNawwo.N 1 <br /> June 2019 D-1 <br />
