Radiological data issues associated with the work performed by TetraTech EC do
extend to building scans and clearances. The Navy has shared these concerns and
findings with regulators, and is supportive of regulators rescinding release
recommendations for buildings where additional data is necessary to confirm that
remediation is complete. The Navy halted all land transfers in 2016 as it
determined the extent of the data issues and is working with regulators on plans for
retesting and remediation of work done by Tetra Tech EC, including impacted
buildings. Additionally, the city and developers have committed to hold on any
further work on UC1, UC2 and D2.
We continue to be confident that there is no threat to public safety. Following the
removal of Building 322 and a Tetra Tech Foster Wheeler (TTFW) scan of the building
and building footprint, an EPA health physicist conducted an independent scan of
the area to confirm that the former building site was clean. The health physicist did
not detect any radiological contamination, so the site was determined to be
transferable without restriction.
A small portion of the buildings on HPNS land were demolished or had materials
removed based on radiological release recommendations. Buildings that have not
been demolished are not accessible to the general public. To date, no areas of
radiation have been identified that would be considered an immediate risk to
human health.
