IV. Subsurface Plutonium. Based upon study of the history of test
operations and upon soil profile data reported in NVO-140, it was
concluded that no soil removal action was necessary to meet the
requirement of Paragraph 4b(4),
600-77,
Tab E, App2, Annex C, OPLAN
No single subsurface sample exceeded
pCi/gm.

IV. Subsurface Plutonium. Based upon a study of the history of test
operations and upon soil profile data reported in NVO-140, a diligent
search was conducted to locate subsurface concentrations exceeding
400 pCi/gm. Those located have been excised and removed for
disposal in accordance with OPLAN 600-77.

suspected locations are not investigated, a special statement will be
tailored to the conditions which are known. )

OPLAN 600-77 defines surface soil concentration as follows: "The
apparent concentration on the surface, as viewed by in-situ detector.
In reality, this is a complex function of the distribution of Pu in the ~
top few cm of soil. Normally expressed in pCi/gm." .
