PAST OPERATIONS
Beryllium brought in facility: YES
Form of beryllium: SOLID
Period of beryllium operations (dates): Start: 1969 End: 1969
Location(s) in facility that contained beryllium materials: Northwest corner of building

Description of beryllium activities: This building, one of several 303 buildings known as a Fresh Metal Storage Building, was built during World War II to store fresh metal (unirradiated uranium), uranium scrap, and chemicals. Based on a 1969 report, it appears that beryllium containing products were machined and fabricated in the facility. However, this could not be verified through discussion with site workers. It is believed that this was an isolated incident.

Building monitoring data summary: The 1969 report identified a single swipe sample collected from the floor in the northwest corner of the building which had a reported result of 0.002 mg/in2.

Personnel monitoring data summary: None identified.
Specify Engineering/Administrative controls used during operations: None identified

Maximum Estimated Past Be exposure: LOW


CURRENT OPERATIONS
Building still present: YES
Beryllium present: Contamination may be present from past machining activities but based on the 2000 characterization results, contamination levels, if anticipated, would be quite low.
Current building occupancy/activity: This building is currently inactive with no occupants.

RECENT SAMPLING/MONITORING: In May of 2000, a wipe sampling characterization was conducted by PNNL, taking 29 surface samples with a detection limit of 0.2 ug/100 cm2. The results were <0.2 ug/100 cm2 in all samples.

Maximum Estimated Current Be exposure: For staff performing building walkthroughs, exposure to beryllium would be minimal. For non-routine activities such as breaching facility systems, exposure levels are unknown.

Basis for above information: Stone and Webster report, publication WHC-MR-0388, and interviews with site personnel.

Comments, including any additional information needed (specify): Levels of contamination are unknown.
