Site Assessment/ Logistical Evaluation N/A -- -- -- --

Performance of an overall Site Assessment and Logistical Evaluation will aid in planning future cleanup work. All areas of the facility will be accessed, documented, and photographed to the extent practical, focusing on features that would impact how future cleanup work is conducted, including the state of existing infrastructure (roads and airstrips), alterations to infrastructure over time (erosion and vegetation growth), and natural features (water sources, barge landings).

Transformer Samples Collected6

30 primary, 3 duplicates, 2

MS/MSDs -- -- -- Thirty surface soil samples were collected for PCB analyses. Ten samples were pre-determined from locations identified in the work plan (USACE, 2017b) and 20 locations were selected by field staff.

Project 17 Miscellaneous

Machinery7 Misc. Machinery 14 locations

(22 items) 1 -- -- Machinery was located, photographed, and inspected for condition, fluids present, staining, and vegetation conditions and then documented of field forms.

Other Potential FUDS Eligible

Site Features7 Features 10 -- -- --

During site reconnaissance activities, other FUDS-eligible site features were encountered, such as landfills, hazardous substances, batteries, suspected-contaminated soil, and areas of suspected environmental impact. When such areas were encountered, they were documented, surveyed, and reported. Quantities were estimated and documented.

Notes:

5 Refer to Table 5. Transformer Inventory for details of each assessed transformer feature.

6 Refer to Table 6. Soil Sample PCB Results for details of each PCB soil sample collected.

2 Refer to Table 2. Drum Dump Inventory for details of each assessed drum feature.

3 Refer to Table 3. Tank Inventory details of each assessed tank and pipeline feature.

Project 2 POL Drums2

Approximately 5,600 POL drums in numerous locations were identified during previous field investigations, with the majority located at the Main Airfield Area. Drum dumps were surveyed and inspected, documented on field forms, photographed, and numbers estimated. The areas surrounding the drums were inspected for evidence of POL-contamination (staining, odors, or stressed vegetation), and surface soils was assessed by screening in-place with a PID.

Project 15 Tanks and

Pipeline Pump Stations3,4

Tanks were located, inspected, documented on field forms, and photographed. Tank construction and structural aspects was recorded, and the surrounding ground surface was inspected for evidence of POL contamination.

All transformers, stands, and historical locations will be located and inspected. Survey equipment with pre-programmed locations will be used to the extent possible to locate items requiring inspection.

Inspections will be recorded on field forms, and photographs take to document each location. Project 16
