2.3.3 SEEDING TECHNIQUES AND RATES (RULES 2.05.4.2(E), 4.15.3) <br />Depending on the site-specific conditions of a given area to be revegetated, seeding will be <br />accomplished at rates indicated in Table 3, 4, or 5 using drill seeding methods. Should <br />conditions warrant broadcast or hydro -seeding methods, the rate will be two times that <br />specified in the applicable table. Seeding in areas managed by the BLM or Forest Service will <br />be in accordance with the rates and application techniques specified (Tables 4 and 5, or as <br />modified) by the management agency at the time of revegetation. <br />As the seed mix is comprised primarily of cool season species, autumn planting will be <br />employed to allow these species to benefit from cold winter temperatures and moisture for <br />spring germination requirements. Planting will be undertaken from September 1 to <br />December 1 of any given year, after final regrading and soil/plant growth medium <br />replacement at a given area to be revegetated. <br />Spring seeding between April 1 and June 15 may be employed if determined to be necessary <br />to minimize potential soil erosion or in conjunction with specific erosion control or <br />mulching products. <br />2.4 MULCHING & SOIL STABILIZATION (RULES 2.05.4.2(E), 4.15.4) <br />In general, mulch will not be applied to areas to be revegetated at the mine site. Whenever <br />practicable and available, native adjacent organic material (litter, brush, branches, logs or <br />other plant material) will be replaced on areas to be reclaimed, as long as placement does not <br />hinder reseeding. <br />In areas with slopes greater than 2.5H:1V, mulch will be applied to minimize downslope <br />erosion after seeding. Mulch may consist of one or more common erosion control materials, <br />including but not limited to; clean straw or hay, coir, hydro -mulch, or erosion control logs, <br />mats, blankets, or other native adjacent or commercially available product. A tackifier may <br />be applied at the rates recommended by the manufacturer to aid in retention of mulch <br />materials on steep slopes. <br />2.5 IRRIGATION AND FERTILIZATION (RULES 2.05.4.2(E)) <br />OMLLC does not propose to irrigate reclaimed areas. <br />Fertilization has generally been found to promote annual and noxious weed growth in <br />natural reclamation scenarios, therefore OMLLC does not propose to employ fertilizer in <br />revegetated areas. <br />2.6 GRAZING (RULE 4.15.5) <br />OMLLC does not propose to employ grazing as a management technique on revegetated <br />areas owned or managed by OMLLC. On areas owned and managed by Hotchkiss Ranches, <br />the BLM, and Forest Service, grazing is allowed and not controlled by OMLLC. <br />2.7 WEED AND PEST CONTROL <br />Noxious weeds will be controlled on the revegetated areas of the mine site. Upon <br />identification of an infestation, OMLLC will implement control measures. Control measures <br />TR -77 H-7 Revised March 2019 <br />
