Evans <br />Re: Permit Application - Continuance File #82-11 <br />Hillyer Pit <br />Mr. Evans: <br />iii iiiiiiiiiiiii iii <br />999 <br />. ~~ - <br />,, <br />:;, R 1 t 1982 <br />Colo Deft of i~!ai~ral Acsoerces <br />We received your letter dated March 26, 1982, with your three concerns. <br />I will address each concern: <br />1. Regarding the reclamation plan: When this pit is no <br />longer needed, the owner will plant native grasses <br />and willows. The grass will be seeded at the appro- <br />priate rates. lJillow cuttings will be planted in <br />areas where the cuttings have a chance to take root. <br />2. The contours will indicate that excavating 21 feet at <br />the upstream end of the pit will cause the bottom of <br />the excavation to be level with the existing ground <br />at the lower end of the pit. <br />3. If the river fails to recharge the available gravel <br />source, then no gravel will be mined. The mining op- <br />eration will be suspended until the pit has been re- <br />charged. <br />Hopefully, this reply will answer any questions that you may have <br />not, please call this office. <br />Respe tfully submitted, <br />Billy Roundtree <br />Colo.
