Attached is a copy of the <br />inspection report. Most of the items identified in the 04/20/2010 inspection report were addressed by the time this <br />report was completed. Overall, the sites were tidy and secure, except for those items mentioned in the rennrL <br />Halogeton at the site is pervasive. <br />As a result of this inspection, the following action items were identified: <br />SEP ®7 2910 <br />Dviisiar, aal <br />1) Continue with herbicide application on site to control halogeton. The frequency of application ve --qtj <br />be increased. <br />2) A fissure was observed on the top of the Topaz dump. Please determine if it is from infiltration of fines or <br />from mass movement. If it is from mass movement, then mitigation methods will need to be devised. <br />3) Check storm water runoff features on a frequent basis to ensure they continue to function properly - for as <br />long as the monsoon rainfall pattern continues. Maintain as needed. <br />4) BLM will continue to monitor toe of dumps for signs of seepage after the monsoonal cycle has subsided. <br />5) Denison should secure the storage shed on the Carnation Mine. <br />6) Clean up additional junk trash and tires identified at the site. This does not need to be done right away, but <br />can wait until the mine is reopened, or the decision is made to idle the site long-term. <br />7) Re-seed the topaz vent after spraying with a BLM approved seed mix. <br />Please contact James Blair in this office at 970-882-6862 to discuss any of these items. <br />Sincerely, <br />Steven K.
