Evaluate the contractor's method(s) of data analysis and evaluation.

Evaluate estimated field production rates and estimated false positive rations, as related

to project cost.

Evaluate proposed changes to OE detection methodologies.

(c) OE detection instrumentation will be tested prior to and upon the completion of the

geophysical survey of each grid to characterize system operation.

(d) A specific standardization test grid will be constructed at the project site. The location

of the standardization test grid will be selected by the OE project team based upon the technical

and site-specific considerations identified by the SUXOS and the project geophysicist.

(e) The standardization test grid will be seeded with inert OE items which are

representative of the items expected to be recovered from the site. The number, orientation, and

depths of the seeded OE items will be sufficient to characterize the limitations of the proposed

OE detection equipment and to evaluate the ability of the proposed OE detection equipment to

located each type of OE at the anticipated depths.

(f) Normally, the grid will be seeded by someone other than the contractor. The grid

typically will contain a known portion and an unknown portion. The contractor will be provided

the test grid location and the location of all seeded items on the known portion. The contractor

will use the known portion of the grid to optimize the proposed methodologies. The contractor

will be evaluated by the OE Design Center on the ability to characterize the unknown portion of

the test grid.

(g) The results of this site-specific OE detection instrument test should be documented and

included in the SOW for the removal action.

c. Geophysical Investigation Plan.

(1) The contractor must prepare a Geophysical Investigation Plan, which is a component of

the project Work Plan. The purpose of the Geophysical Investigation Plan is to document the

methodology for completing the geophysical investigation. The required contents for the

Geophysical Investigation Plan are discussed in the OE MCX DID OE-005-05, "Geophysical

Investigation Plan", which is located on the OE MCX website at
