5. The depth of the mine and the berms which was mentioned above in the landscaping section will <br />also help to minimize the dust from the operation. <br />D Noise <br />The only residences not owned by La Salle Aggregates or Bean that aze within 250 feet of the permit <br />azea are houses on the Appelhanz, Moon, Nation, and Corey properties. As such the amount of noise <br />which is emitted from the mine will be minimized as much as possible. Haldorson Sand and Gravel <br />commits to establishing a maximum noise level of 80 db at all times at the edge of the permit azea. <br />The 8 feet high berms which are placed around the perimeter of the pit will also help to reduce the <br />noise outside of the permit azea once the operation breaks the surface. <br />The fact that once the initial pit on the former George Property is dug to near the bottom, 45-50 feet <br />down, noise will be greatly minimized since all mining and processing will occur at the bottom of <br />the pit. Mining on the Metcalf and Bean Properties will occur from the bottom of the gravel, thus <br />minimizing noise in these areas. <br />E) Haul Routes <br />The gravel will be hauled to market using 10 cy trucks or 24 ton belly dump trucks. The road access <br />for this amendment will not change from the existing conditions. All truck traffic leaving the mine <br />will either exit onto the 6175 Road or the 6200 Road via current permitted access ways. The access <br />to 6175 Road currently exists where the mining operation has started in Phase 1 of the old permit, <br />where the DMG granted the Haldorson Sand and Gravel to mine to a depth of 13 feet. The access to <br />the 6200 Road will be the existing access way to the Metcalf Pit. Through mining this access to the <br />pit will change locations; however only one access way will be active onto the 6200 Road <br />throughout the minelife. The only impact that the mine poses on the County is an increase in traffic <br />on 6175 Road, 6200 Road, LaSalle Road, and other local roads needed for transportation to the <br />vazious job sites where the finished product will be transported. It must be noted that this impact is <br />identical to what has already been approved in the 2003 Special Use Permit since this new proposal <br />does not increase annual production. <br />Haldorson Sand and Gravel Mine 20 <br />
