1154 March 25, 1998; updated January 26, 2001 Port of Benton Charles Kasch |
PAST OPERATIONS
Beryllium brought in facility: YES
Form of beryllium: SOLID
Period of beryllium operations (dates): Start: pre-1984 End: 1996
Location(s) in facility that contained beryllium materials: Some
radio transistors contained beryllium.
Description of beryllium activities: Radio maintenance facility. Some radio transistors contained beryllium which, on occasion, generated a powdery residue.
Building monitoring data summary: One swipe sample was collected in 1984 which contained "trace amounts" of beryllium.
Personnel monitoring data summary: None identified.
Specify Engineering/Administrative controls used during operations: Industrial hygienist recommended awareness of potential presence of beryllium in transistors and damp wiped transistors if powder observed.
Maximum Estimated Past Be exposure: NONE
CURRENT OPERATIONS
Building still present: YES
Beryllium present: NO
Current building occupancy/activity: This building is currently
occupied by Port of Benton.
2000 Study Results: Characterization of this facility was performed on 5/19/00 by PNNL for DOE-RL. Lockheed - Martin's Y-12 plant lab, analyzed wipe samples taken on 5/19/00. The wipe samples were collected from the Eastern half of the building where radio maintenance had been performed. 28 of the 29 samples taken were below the detection level of 0.1ug/100cm2 with one at 0.148ug/100cm2. The only sample above the detection limit was taken from the surface of an electrical breaker box, not in the shop areas of the building. Based on this test data, it was concluded that prior beryllium from radio transistors does not present a risk of exposure to beryllium now or in the future. These results were communicated to the Port of Benton by DOE-RL. It should be noted that this building should be identified with a suffix "A" to correspond with maps that were in place when this facility was turned over to the Port.
Maximum Estimated Current Be exposure: NONE
Basis for above information: Stone and Webster report and interviews with facilities management personnel.
Comments, including any additional information needed (specify): All equipment was removed and the building cleaned prior to transfer to Port of Benton.
