f. Plowing and/or mixing are not desirable or suitable techniques for meeting cleantp criteria. Both could be used after cleanup but must be | carefully considered and justified. 3. Recommencations: The chairman recommends that the following program outline be transmitted to Commander, JTG for execution generally in the sequence listed, although some actions may be performed concurrently based on availability of assets. a.° In coordination with ERSP, establish, survey and mark, a 50 meter grid for the northerm-half of Runit. b. Utilize FRST, other resources, and portable field instruments to search out and remove very small "hot spots" and plutonium chunks. This effort should initially be confined to the FIG/QUINCE area, concentrating on the areas shown as D level or higher concentration on the YVONNE June- July 1977 aerial survey. This effort is visualized as a locate-and-measure-~ and-shovel-and-bag operation. of surface contamination. It is not intended to excise extensive areas Its purpose is to attempt to pick up milligram and larger particles of plutonium concentrated in very small areas, generally less than one meter square. Removing such very high contamination level spots should reduce the size of the areas which in-situ survey will characterize as greater than 400 pCi/g, thus reducing the volume of surface soil to be excised. This effort should be carefully monitored and if it appears unproductive, should be stopped. Location, amount excised, and estimated activity for each excision should be recorded. for crater containment. Excised soil should be held
