,~{~~3 <br />15. The de ' gradefor ditch routing from Pond # 1 to Pond tt5 is specifically noted on page 7 <br />of the narrative as 1%-2%. This grade will be cut in solid granite bedrock and will not be <br />subject to erosion or a d to sediment to ~ng of the ediment pond system dovmstream of Pond <br />~ 1. ~oZO z rs' ~ .J ~ <br />3o'~lti-~ t; ~ s f. ~.s 7s -90 ~o~~ o4.~wf-~ <br />lb. Storm ditch construction from Pond to Pond 3 thence Pond 4 follows the existing main <br />haul road which is paved to prevent eroston and sediment loading. Shoulders along both sides of <br />the existing haul road are lined with 4"-8" rip-rap and bedded in concrete to help retain an <br />E:rosion free surface while slowing down water velocities as much as possible on the IO% slopes. <br />"fhe operator will attempt to widen and deepen the rock and concrete lined shoulder ditches to a <br />three foot wide dimension at the bottom of the ditch one foot lower than the road surface <br />wherever possible. Ditch side slopes will be no more steeper than 2 :l. Lined ditches will be <br />constructed so that stormflows are directed into the ditch rather than down the paved roadway. <br />Once the new haul road is in place, asphalt "speed bump" deflectors will be installed along the <br />lower reac a o~ f the paved @:~ ing~ad o her direct sto wa rs into ond~~~~ <br />1T±The S •WMPeirtde~taivls~as~shown describe t/h3e-use of Typar Geotextile ass (CDOT) liner ~~~~- <br />keyed into subgrade minimum 6" at top and bottom of ditch transfer runs.

The applicant acknowledges the Division's comments on rip-rap grading and intends to <br />fr~llow the standard grading distribution as outlined m CDOT mixed rip-rap grading range. <br />1!~A copy of the finalized agreement pertaining to the alternative haul road between the City of <br />~J~ ~ Canon City and Tezak Heavy Equipment Co is under draft at present and will be included in the <br />p'-"'„p~ permit package as soon as it ~s available after signage. <br />? 20. Reclamation Cost Estimates-- As outlined in the Reclamation Cost Exhibit L, most of the <br />' information requested is listed on page 22. For the convenience of the Division, 1 will attempt to <br />list the information in the order is was requested and refer to those items/areas on page 22. <br />List of equipment necessary for final reclamation-- Bulldozer with Ripper, tractor with disk <br />and/or drag to help cover broadcast seeding prior to mulching and crimping with disk, Main pit <br />area estimate for reclamation including all roadways--44 acres. $2200/ acre reclamation cost as <br />follows: Bulldozer cost $100/hour or $300/acre finish grading and ripping, tractor cost $ 150/acre <br />for seeding and crimping, seed and mulch cost $300/acre, top soiling cost estimate $14501acre <br />deiivered based on 1500 tons per acre. At this time the applicant would rather estimate top <br />soiling needs based on purchasing of topsoil/planting media rather than projecting a borrow pit <br />on Tezak property to supply such material. The bottom 12" of planting media will be from fines <br />produced on site, ripped prior to the topsoil application over the top 6". <br />Equipment mobilization and demobilization is covered on page 22 under Mobilization. There <br />will little equipment to demobilize as it will be integrated into the construction company's fleet <br />yard at duration of mining. There are no concrete slabs to remove or bury other than scale <br />4 ~~ <br />4P° +~~-°°S+q <br />
