EA-1384: Finding of No Significant Impact

Proposed Improvements at the Thomas Jefferson National Accelerator Facility, Newport News, Virginia

DOE evaluated the potential environmental impacts from proposed construction of various site improvements and the proposed installation and operation of the Helios light source at Jefferson Lab. The Southeastern Universities Research Association, Inc. operates Jefferson Lab (SURA) under contract to the DOE. With this proposal, DOE intends to construct no more than four major two or three story additions to CEBAF Center, the main facility administration building, and the addition of three new single story and one two story operations support structures on the accelerator site. The proposed action also involves the installation and operation of the Helios(High Energy Lithography Source) accelerator in the Free Electron Laser (FEL) addition.
