replacement of topsoil and seeding and installation of plantings on the pond <br />embankments. Undisturbed areas will be managed for weed control until <br />mining commences on each phase. <br />e. Timing: The applicant anticipates that mining will commence at the end of <br />2003 or beginning of 2004. The estimated size of the gravel deposit on this site <br />is 6.3 - 6.5 million tons. Hall-Irwin estimates it will take approximately 18-20 <br />years to mine and reclaim this property. Annual production is estimated to be <br />between 300,000 and 500,000 tons. This may vary depending on the demand <br />for construction material and may impact the total life of the mining operation. <br />f. Nature, depth and thickness of the deposit to be mined and the thickness <br />and type of overburden to be removed: Terracon performed a geotechnical <br />engineering exploration of this site and prepared a report on January 31, 2000. <br />Please refer to Exhibit I -Soils Information, of this Application for a copy of <br />the Geotechnical Engineering Report. The nature, depth and thickness of the <br />deposit to be mined and the thickness and type of overburden to be removed is <br />described in detail on pages 3 and 4 of that report. <br />The primary commodity to be mined/extracted is sand and gravel. The intended <br />use is for this aggregate is construction materials. Secondary commodities to be <br />mined include screening and sale of topsoil not needed for reclamation of the <br />site. Anticipated incidental production may include gold that is recovered as <br />part of the standard washing and screening operation. <br />Hall-Irwin Corporation Page 16 of 35 <br />MLR$ 112 Permit Application <br />
