This Environmental Checklist (EC) is being revised to include work activities, conditions, and instructions associated with encountering asbestos containing building materials. The proposed action would modernize the argon purification system in the Hot Fuel Examination Facility (HFEF) at the Materials and Fuels Complex (MFC) building MFC-785. The HFEF argon purification system consists of three basic parts: 1) analytical system, 2) hydrogen injection system and 3) purification/regeneration system. The project would use a phased approach, completing upgrades to the three parts of the air purification system individually in the order previously listed. The proposed action would install a temporary analytical cabinet in the appropriate areas of HFEF and connect it to the associated portions of the purification system.
