Given this precipitation distribution, two seeding windows are proposed. <br />A spring seeding window would take advantage of increased mid -late <br />summer precipitation, encouraging summer growth and allowing plants <br />to add sufficient biomass prior to winter. A second autumn seeding <br />window allows seeding into relatively moist ground, but prevents <br />significant seedling growth prior to freezing, allowing seeds to remain <br />dormant over the winter with adequate moisture for early germination in <br />the spring. Two optimal windows for re -vegetation seeding are proposed <br />dependent on the observations described above; a spring window from <br />March 15 to June 15 and a fall window from August 15 to November 15. <br />Vegetation seeding will occur during the first planting window after <br />completion of work within the re -graded and topsoiled area. <br />Seed Mix <br />The seed mix for the re -vegetation of the King II Mine was developed <br />based on the stated post -reclamation land uses of rangeland and fish <br />and wildlife habitat, and the goal of reestablishing vegetation <br />communities characteristic of the pre -disturbance landscape and <br />complementary to those vegetation communities currently existing <br />outside the areas of disturbance. <br />A seed mix for the mine site requires species adapted to predominantly <br />loamy soils. The plant species must be adapted to xeric and potentially <br />droughty moisture conditions, given the predominantly south and <br />southwest exposures of the area to be reclaimed. The majority of the <br />species selected were cool season, complementing the adjacent native <br />vegetation. The species selected were robust, and either tall or bushy to <br />provide wildlife cover and forage. A mix of warm and cool season species <br />was developed to provide wildlife with cover and forage throughout the <br />growing season. Graminoids, forbs, and shrubs to be seeded provide a <br />mix of plant morphologies and structures. <br />Application Methods <br />Drill seeding will be employed in all areas where slopes are 3:1 or less <br />and equipment access is not a problem. In the remaining cases, <br />broadcast seeding will be employed. <br />GCC Energy, LLC <br />Page 10 <br />Section 2.05.4 <br />Page 10 <br />July 11, 2017 (RN -07) <br />King II Mine <br />
