MINING PLAN <br />the event that expected replacement does not occur in the time frame initially anticipated, appropriate <br />protective measures will be taken. <br />Some Examples: <br />1.) Soil stripped between September and March and expected to be replaced by June of <br />the following year, need not be protected. <br />2.) Soil stripped between September and March and expected to be replaced later than <br />June of the following year, must be protected. <br />3.) Soil stripped between September and March and expected to be replaced in June, <br />but in April or May it is found that it will not be replaced until later than July, must be protected as <br />soon as it is determined that it will not be replaced as originally anticipated. <br />4.) Soil stripped during the primary growing season (April through August) will be <br />protected. <br />REQUIREMENT: For stockpiles that are in place into a growing season, the stockpile <br />will be monitored to watch for the growth of noxious weeds. If noxious weeds appear in the stockpile, <br />appropriate action will betaken to eradicate the noxious weeds. Appropriate action maybe the use of <br />herbicides or physical removal of the plants. Normal "tumbleweed" development (Kochia or Salsola) <br />need not be controlled unless the growth is so dense that it endangers the success ofprotection species <br />that have been planted. <br />Discussion: Although noxious weed growth in stockpiles has been a very minor problem <br />in the past, it cannot be assumed that will always be the case. The presence of noxious weeds in the <br />stockpile, especially if they are allowed to grow and reproduce by seed or vegetative means, may <br />cause even more problems after the soil is spread and revegetation begins. Therefore, controlling <br />noxious weeds in stockpiles reduces, but usually does not eliminate, the need for weed control in the <br />final revegetation. It is far more economical to control the problem when it begins than to wait until it <br />becomes a widespread problem. <br />REQUIREMENT: Protective seeding of stockpiles, when needed, will utilize the seed <br />mixture shown in the "Stockpile Seed Mixture" section of this Mining Plan. <br />Coal Creek Sand Resource Amendment 3 (2005) - M-1988-044 Exhibit D Page 32 <br />
