The use of emission control systems on mixed waste storage tanks is a critical issue as characterization and remediation of tanks becomes a leading priority at DOE sites. The current tank ventilation systems, where installed, are designed primarily for the control of radionuclides with no treatment systems incorporated for toxic emissions. Many of the tanks also lack ammonia treatment systems, although ammonia, due to its noxious odor, is controlled in some applications. The need for emission control systems has become apparent by the numerous occurrences of occupational employee exposure and the buildup of toxic and/or flammable materials in the vapor space of tanks. This paper will focus on two alternate systems for the control of toxic emissions, and will provide a discussion of the key issues which must be addressed for each system. The contents of this paper are the results of two efforts being performed by Engineering-Science, Inc., under the contract to Battelle Environmental Management Operations (EMO), for the Westinghouse Hanford Company. These efforts are for the study, design, fabrication, installation, and testing of new modular exhaust units for the 241-C-103 Tank and for several tanks which are candidates for the Rotary Mode Core Sampling (RMCS) characterization. If one exhaust system can be used in several applications, during high activity and personnel exposure periods, then a tremendous savings to the capital investment needs, the annual operating budget, and decontamination and decommissioning costs can be realized.
