air survey company. The aerial survey should be current so that all improvements are shown and

must also meet established OE Design Center requirements for aerial mapping.

(a) The OE project team will conduct a ground reconnaissance (ground RECON) to verify

the results of the spatial analysis. During the ground RECON, the OE project team (which will

include an OE Safety Specialist) will look for evidence of OE contamination such as changes in

vegetation, soil characteristics, and ground scars. A ROE may be required prior to the ground

RECON.

(b) If no evidence of OE contamination is found, then NDAI will be recommended. If OE

that may present an imminent danger to the public is found at a site, USAESCH must be

contacted by phone to discuss interim actions. USAESCH should coordinate with local law

enforcement officials to secure the site and ensure that the local EOD unit has been contacted.

USAESCH will then coordinate with EOD and may provide an OE Safety Specialist to assess the

risks and recommend a course of action.

(5) Technology Evaluation.

(a) The purpose of the technology evaluation is to determine which OE detection

instrument is most appropriate for a specific site within a reasonable cost. During this task,

various OE detection instruments will be evaluated by establishing a test grid.

(b) The location of the test grid will be based upon ASR information, visual review, and a

sweep with an ordnance detector. The test grid will then be seeded with representative inert OE

items within the range of depths that the ordnance is expected to be found at the site. When the

test grid is established on a property, a ROE may be required. ROE requirements are discussed

in Chapter 3.

(6) Analysis Report and Data Archive. The results of the ASR analysis, spatial analysis,

ground RECON, and technology evaluation will be compiled into an Analysis Report and Data

Archive. The OE project team will use this information to:

(a) Develop the EE/CA SOW.

(b) Develop EE/CA planning documents (i.e., Work Plan, SSHP).

(c) Provide evidence that, in some cases, the OE response should proceed directly into a

removal action without further study. If the removal action will be conducted with a planning

period of less than six months, the Action Memorandum must be published within 60 days of

initiating the removal action. A 30 day public review period is also required. Any information

gathered during this response action should be incorporated into the EE/CA document.
