2_.2. Sediment Control System Gravel Mining <br />The sediment control system for the gravel operation has been absorbed into the sediment control system <br />for the area north of Access #1 and is described in Section 1.2 of this Exhibit D. <br />2.3 Access Roads <br />All access roads are described in Section 1.3 of this mine plan. All trucks that leave the site for the gravel <br />operation will use Accesses 1, 4 or 6. All traffic supplying product demand to the south of Alma will <br />enter Highway 9 using Access 1 or 4 so that the traffic does not go through the town. Every effort will <br />be made to minimize the truck traffic through the town for all demand that exists to the north. As <br />described in Section 1.3, the roads will either be watered or sprayed with magnesium chloride to keep <br />dust down. These measures will be done on an as needed basis to ensure that dust is <br />kept to a minimum from the truck traffic. All trucks will also be covered as they leave the site and will <br />not track mud onto the Highway. <br />2.4 Topsoil Handling for Gravel Operation <br />As previously described, all disturbed area for the gravel portion of the disturbed area has been previously <br />disturbed with no topsoil salvaged. This area is 40.5 acres. The 110 area of 11.8 acres has been regraded <br />and will be reclaimed using fines from the stockpiles on site. Approximately 25,000 cy has been salvaged <br />from Ponds #1 - #4 as of January 2015 This has been placed in Fines Pile #1 and #2, as shown on Map <br />C-2. These piles will have slopes no steeper than 2.5H:1 V and will be seeded according to the following <br />mix: <br />Alma Place Mine 01/15 32 <br />
