Assessment of Unabated Facility Emission Potentials for Evaluating Airborne Radionuclide Monitoring Requirements at Pacific Northwest National Laboratory - 1999

Abstract

Portions of this document may be illegible in electronic image products. Images are produced from the best available original document. Summary Assessments were performed to evaluate compliance with the airborne radionuclide emission monitoring requirements in the National Emission Standards for Hazardous Air Pollutants (NESHAP-U.S. Code of Federal Regulations, Title 40 Part 61, Subpart H). In these assessments, potential unabated offsite doses were evaluated for emission locations at facilities owned by the U.S. Department of Energy and operated by Pacific Northwest National Laboratory (pacific Northwest) on the Hanford Site. Two of the facilities evaluated, 325 Building Radiochernical Processing Laboratory, and331 Building Life Sciences Laboratory met state and federal criteria for continuous sampling of airborne radionuclide emissions. One other building, the 3720 Environmental Sciences Laboratory, was recognized as being in transition with the potential for meeting the continuous sampling criteria. The assessments were performed using building radionuclide inventory data obtained in 1999. The list of buildings evaluated is provided in Table S. 1.
