help comply with state and erosion standards. Revegetation activities will take place immediately <br />upon completion of reclaimed slopes (season permitting) whenever practically sized areas <br />become available and free from mining activity. Areas not planned for revegetation include <br />Phases 1, 3, and 4 as they will become below -grade ponds. Based on SCS guidance for other <br />local projects having similar surficial soils, the following revegetation procedures are <br />anticipated: <br />• Grass seed will typically be planted in unfrozen soil between October 1 and April 30 <br />• Grass seed will typically be planted with a grass drill, or where necessary, with a <br />broadcast seeder <br />• The proposed seed mix and application rates in pounds of pure live seed per acre are <br />described on the following pages <br />• Weed control practices will be implanted as required. <br />Weed control measures will not change from the 2011 reclamation permit amendment. <br />Fertilizer usage will not change from the 2011 reclamation permit amendment. <br />The above procedures may be modified as conditions dictate. Weeds will be mowed before they <br />go to seed during the first growing season. Plant species anticipated to establish themselves <br />naturally along the shorelines include cattails, willows, cottonwoods, and bulrushes. Proposed <br />seed mixtures to be used on site where appropriate are listed below. Availability may dictate the <br />need for substitution.
