B'''pi. f~~ ~ ural~Re o~fCestd ~ ~ <br />During your October 1963 inspection of the Seneca II Mine, several <br />areas of concern were noted which were subsequently identified in <br />the inspection report. These areas were also discussed during a phone <br />conversation we had a short time later. <br />The following information is presented as clarification or re- <br />commended changes based on those items discussed in section III. <br />Comments - Compliance, 4.15 Revegetation of the October 31, 1983 Inspection <br />Report. <br />Seeding at the Seneca II Mine is done with a Rangeland drill. <br />On steeper areas, seed is broadcast. The Rangeland drill is limited <br />to seeding a mix up to a rate of 20 lbs. Pure Live Seed per acre. <br />The seed mixes listed in Tab 13 "Post Mining Land Use Plan" are all <br />higher than this and will be reduced to conform to the actual field <br />situation.
