(e) Reduce the cost and time required to conduct the EE/CA through the implementation of

sound engineering methods.

(2) These objectives may be achieved by:

(a) Obtaining additional historical and site-specific data to determine the nature and scope

of the EE/CA site investigation. The data collected during the RECON task should be suitable

for incorporation into the Geographic Information System (GIS).

(b) Defining the geographical extent of the ordnance contamination at the site through the

use of aerial photography and a GIS.

(c) Determining the best type of OE detection equipment to use at a site during the EE/CA

site characterization.

(d) Determining the best field methodology for completing the EE/CA phase.

c. RECON Elements. The RECON task consists of six sub-elements: Work Plan/ASSHP;

Analysis of the ASR; Spatial Analysis (Aerial Survey); Ground Reconnaissance; Technology

Evaluation; and Analysis Report and Data Archive. These sub-elements are illustrated in Figure

9-2 and discussed in the following paragraphs.

(1) Work Plan/ASSHP.

(a) The OE Design Center is responsible for executing the Work Plan. The Work Plan will

be submitted to the district for review and written concurrence or non-concurrence. The OE

MCX will monitor the Work Plan.

(b) Since RECON activities will be non-intrusive and anomaly avoidance techniques will

be implemented, an ASSHP will be prepared in accordance with the guidance provided in

Chapter 20.

(2) Analysis of the ASR. The OE project team will build upon existing ASR data and any

subsequent data; for example, local law enforcement or EOD records. The data will be converted

into a spatially coincident digital format. This conversion of data will allow the historical and

site information to be used throughout the project.

(3) Spatial Analysis (Aerial Survey). The OE project team will complete a detailed

analysis of spatial data. Spatial analysis may provide information to assist in making valid

decisions regarding predicted areas of interest at the site by differentiating potentially

contaminated areas from uncontaminated areas. This is accomplished through spatial analysis of

the ASR data and, if necessary, by completing an aerial survey of the site. The aerial survey may

be either specifically flown for the project or a recent aerial survey may be obtained from a local
