DP Section 3 - Radiological Status of Facility 14 Structures
- All former processing buildings - released.
- CERT Office continues to be used.
- Routine surveys demonstrate that ongoing decommissioning activities don't impact the CERT Office.

- There are no operating systems remaining on site.
- Release surveys are conducted on equipment that may become contaminated during use.
- Field equipment (e.g., excavators, loaders) that contacts subsurface material is pressure washed and surveyed prior to release from the site.
- Two plastic tanks and one concrete slab have been identified as contaminated and retained on site.

Public & Occupational Health 24 Public Exposure No measurable exposure to members of the public during construction or operation.
Worker Exposure Highest exposure is at resin vessels. At 1 from the fully loaded resin vessel calculated exposure rate is < 30 piR/hr.
Potential exposure from extractions* injection, water treatment, and waste packaging and shipping activities combined will be < 100 mrem/yr.
