The area will be fine surveyed and isopleths drawn
which define the region which exceeds local background.
(>)
;
Vertical soil profiles will be taken to evaluate
the effectiveness of excavation as a means of reducing the Resuspension
Potential.
(c)
An-iterative excavation plan will be executed to:
1.
Reduce the half hectare area average concentration
2.
Reduce the average concentration of the "defined
below 100 pCi/g.
region'' to some lower number which shall be determined by cost-benefit
considerations but will usually not be below local background.
(d)
The region will be resurveyed and the results
documented.
(3)
Condition C:
When a quarter hectare is determined by
either direct measurement or extrapolation to exceed 40 pCi/g (at
the 67 percent confidence level number), the following actions will be
taken:
(a)
The area will be fine surveyed and isopleths drawn
which define the region which exceeds local background.
(2}
;
Vertical soil profiles will be taken to evaluate the
effectiveness or excavation as a means of reducing the Resuspension
Potential.
(c}
An iterative excavation plan will be executed to:
1.
Reduce the quarter hectare area average concentration
