74.131(4)(f) Revegetation Plan: All disturbed topsoil and non salable materials existing <br /> on the site will be stockpiled for reclamation of the pit floor. A minimum of four inches <br /> of combined topsoil, topsoil substitute, and mine waste will be spread across the floor of <br /> the mine. Following grading and scarifying the topsoil, Mixture 20 grass seed will be <br /> planted per Wis DOT specifications 630. An equal amount of annual ryegrass shall be <br /> added to the mix. Seed mix shall be applied at the rate of four(4) pounds per 1,000 <br /> square feet. Fertilizer shall meet the minimum proportions of nitrogen 16%, phosphoric <br /> acid 8%, and potash 8%. <br /> 74.131(4)(g) Quantifiable Standard: Grass cover expected will be comparable to grass <br /> on existing fields above the existing quarry. Existing topsoil is thin and plant growth is <br /> somewhat limited. See Exhibit#2. <br /> 74.131(4)(h) Erosion Control Measures: The quarry is located on a ridge, and no offsite <br /> runoff will flow into the quarry. Mining will be below the surrounding ground surface <br /> and no quarry runoff will leave the quarry. Surface runoff in the reclaimed quarry will <br /> flow down very flat slopes to the northwest side of the quarry. Ponded water will <br /> percolate into the sand and gravel. The total drainage basin after reclamation will be <br /> approximately 20 acres. This is derived from adding the reclaimed 10 acres of the <br /> working quarry (south 10 acres) to the already reclaimed north 10 acres. Initially, <br /> stripped topsoil will be stockpiled above the quarry along South Park Street and <br /> Koshkonong Road. Stockpiles will be seeded and silt fence installed along South Park <br /> Street and Koshkonong Road. As the mine expands, the topsoil berm will completely <br /> surround the quarry. Later stripped topsoil will be hauled directly to the mine floor for <br /> stockpiling and/or reclamation. <br /> 74.131(4)(i) Interim Reclamation: Reclamation will proceed in finished areas as soon as <br /> operations allow. Areas required for the mining operations and not reclaimed will be <br /> measured each year to determine bond per 74.141 Financial Assurance; Requirements <br /> (typically at$1,500 per acre—see 74.141 (3)(a)). <br /> Mining Reclamation Plan 4 <br /> JH-09-14 <br /> 5/6/2014 <br />
