• 30 kw diesel generator with 5 gallon diesel tank with secondary containment built in (to power <br />the trommel and pump at the Settling Pond to recycle water to the sluice) <br />No blasting will take place in this operation. No chemicals will be used. No fuel or oils will be stored on <br />site and these liquids will be brought to the site by service truck. Any spills of fuel or other hazardous <br />material will be reported to the Division as soon as they are discovered. <br />Section 4.0 Highwalls and Backfdling <br />As a result of extensive Hydraulic mining done decades ago, some pre -law highwalls exist in the permit <br />area. Large rocks and wash plant reject will be used to correct the hillside slope back to minimum <br />3H:1 V slope. Overburden and most of the washed material will likely be backflled. The cross sections <br />on Map C -2 show 2 scenarios for backfilling. One assumes that most gravel and sand will be sold, <br />therefore, the 3H:1V slope will be the final slope. The more likely scenario is that only a small amount <br />of this material will be sold, so that the original landscape will be restored, except in those cases where <br />the existing landscape is steeper than 3H: IV. In those cases, 3H:1V will be restored. Fines from the <br />wash plant settling pond will be used to provide a subsoil material on the backflled surface. This will <br />provide better stability for Highway 9 than the current slope provides. A series of roads will remain to <br />access different areas of the site. <br />Section 5.0 Topsoil Removal and Stockpiling <br />Much of the site was disturbed over a century ago and no topsoil was salvaged from this operation. All <br />the topsoil uncovered by the new operation will be stockpiled and used to cap the reclaimed areas in <br />preparation of replanting. The topsoil stockpile locations are shown on Map C -2. It is expected that the <br />undisturbed areas will yield a topsoil salvage thickness of approximately 6 inches. This material will be <br />used to cover all areas that are designated as wildlife habitat on Map F -1. Some areas will be left for <br />roads, residence and commercial development, which will not be topsoiled. <br />All topsoil fines piles will be constructed to 2.5H IV slopes and will be seeded and mulched if they are <br />to be in place over two years. The temporary seed mix for any topsoil or substitute fines piles is given <br />below: <br />Sullivan Aggregate Pit March 2015 D -5 <br />
