<br />Larry Oehler <br />- 10 - <br /> <br />7 <br />The Division recommends that a non-competitive annual or bi <br />crop be seeded in the forest community "islands" during the <br />years of reclamation. Then Arizona Fescue and Mountain Mut <br />interseeded at a reduced rate during the 3rd year. This pr <br />reduce erosion between seedlings, promote soil development, <br />seedlings several growing seasons to developing their deepe <br />before competing with the shallow rooted native grasses. <br />5. Mulch <br />Reclamation Resources states that mulching and protection a <br />and water erosion are not needed because of the absorptive <br />characteristics of the gravely soil <br />The Division disagrees'wi is sta ement for the followin <br />a Iu3 fY <br />A.

Evaporative losses will occur during application o err <br />The Division recommends the application of two (2) tons per <br />hay mulch or crimped straw mulch and use of a protective bi <br />netting over seeded areas to minimize erosion and evaporate <br />promote re vegetative success at the Alma Placer. <br />6. Irrigation Water - Source <br />Reclamation Resources has indicated that the source of irri~ <br />to be used during reclamation is the Columbia Ditch. Please <br />the required water rights will be secured prior to reclamat <br />Alma Placer. <br />Exhibit G - Hydrology <br />Winter Freeze Up - Spring Thaw <br />The applicant has mentioned in Exhibit K -Climate that the anti <br />working season for digging gravels extends from mid-April until r <br />and the freezing up of the water supply determines how long into <br />processing plant can operate. <br />Please address the water management system and plans for shut-do' <br />winter months. Reclamation Resources should address how spring <br />ground water recharge within the disturbed area will be handled <br />designed storage capacity of the recirculation ponds be availably <br />mid-April? When will the recirculation ponds begin operation? <br />recommends that the recirculation ponds be partially drained or <br />to fall shut-down. This procedure should minimize the potential <br />overflow during spring snowmelt. <br />TAS/yjb <br />cc: Steve Renner <br />John Doerfer <br />April 4, 1990 <br />~nnial cover <br />first 2-3 svOfr~`f <br />ly can be ~,~:~' <br />ictice will <br />and allow the <br />• root systems <br />ainst wind <br />reasons. <br />"Cp <br />mer.~f1`~ I ~ <br />the growing co~~ <br />e expectedon v day <br />ation Ovate- r~ <br />acre native <br />degradable <br />n and to <br />lotion water <br />verify that <br />on at the <br />r`i gated <br />lid-November <br />the fall the <br />during the <br />owmelt and <br />Will the <br />in <br />e Division <br />ptied prior <br />or pond <br />bass <br />
