will be no different in method for certification, the history of the island
and available data do indicate a probable requirement for higher density
survey than may be required for other islands.
This led
to a discussion
of the advantages and disadvantages of placing contaminated stockpiles on
relatively wncontaminated areas.
It would generally be better to put
contaminated stockpiles in areas known to be contaminated to similar or
higher levels.
The "cool" area requires relatively few sampling sites and
characterization effort.
15.
It was agreed that when resources permit it would be highly desirable
to use one IMP to further refine the area of surface contamination to be
removed.
These areas are defined, in the Fig/Quince Area, by aerial
survey contours.
The Cactus Crater area is not defined.

to place the contaminated stockpile in the "hot" area may interfere with the
refinement would assist considerably in refining the estimates of area, and
thus volume, to be excised.
Mr. Church proposed to use the JMP only to
move im toward hot areas and define the periphery of those areas over
400 Pci/g.
This would not be a full survey but would refine the area

There
was discussion of use of this "peripheral" technique as compared to a full
‘survey.
It was agreed that the peripheral technique would not totally define
the surface area but certainly should provide better estimating data than the
