Mr. Peter V. O'Connor September 8, 1983 <br />RE: La Poudre Sand & Gravel, Inc. File Nu. 83-90 PROJECT N0. 139-811 <br />C-2 The topsoil and overburden will be maintained in separate stockpiles. <br />This procedure will be stated on the Mining Plan. <br />C-3a. It is anticipated that the topsoil stockpiles will be maintained at <br />a minimal size and length of time.. The initial phase of the "block" <br />mining procedure will produce the maximum amount, Thereafter, thr_ <br />topsail will be replaced duriny each phase. A 3h to lv slope will <br />be sfrnwn for topsoil stockpiles. <br />C-3b If more than adequate replacement topsoil is available and needs to <br />be stockpiled for snore than one growing season, the operator will <br />establish proper 3:1 grade and seed with the suggested grass mix for <br />the reclamation of the landscaped areas with the addition of 1# per <br />acre of Red Clover or Strawberry Clover. (See Page E-3). <br />C-4 The final pond slopes to 10 feet below waterline will be 4h: lv and <br />map corrected to show this slope. <br />C-6 The Plrase, Pit and Pond numbers all relate to the Same area and are <br />used interchangeably depending on the actual area and specific point <br />or time of operational sequence. <br />C-6 Large Arch-type culverts will be laid in the bed of the river to pro- <br />vide the temporary river crossing. It is anticipated these will be <br />60" Arch Pipe by 24 long of adequate number to carry the normal flow. <br />High flow spring runoff will be accommodated by adequate by-pass channel <br />or r•einoval of the temporary crossing during this period, All plans <br />and procedures regarding this crossing will be worked out with the <br />Corp of Engineers. <br />C-7 The access roads throughout the area will be 24'± wide with drainage <br />ditches to provide stability. The river crossing will be about 16' <br />wide on top of the 24' long arch pipes. <br />2 <br />
