12 GeV Upgrade
On July 30, DOE convened an Energy Secretary Acquisition Advisory Board (ESAAB) meeting which resulted in the approval of Critical Decision-4A for the 12 GeV CEBAF Upgrade project. This very important milestone marks the completion of the accelerator and civil portions of the project necessary to mark the transition to initial operations of the 12 GeV facility. This decision was supported by the important accelerator commissioning milestones achieved in spring 2014. The attention of the 12 GeV Project Team will now be focused on Hall D beam commissioning this fall, and on completing the physics experimental equipment in Halls B and C by September 2017.

Facilities Management and Logistics
CEBAF Center A & C Wing Restrooms to Close Temporarily for Refurbishment
Phase I includes Wing A restrooms on the first and second floor.
Phase II includes Wing C restrooms on the first and second floor.
Phase I work is set to begin on Monday, Aug. 11, and should be completed within four weeks. Phase II work is planned to begin immediately thereafter and should take about the same time. Notification will be made in advance of the start date for Phase II.
Notices will be placed on the restroom doors while they are closed. The notices will include locations of other restrooms. The anticipated project completion date for all phases is late September. Facilities Management appreciates your patience during this brief inconvenience, as we work to provide safe, sanitary and upgraded restrooms.
Environment, Safety, Health and Quality
Resolving ES&H Concerns
The DOE DPO process ensures that all JSA employees and contractor employees have the right to report environment, safety, and health technical concerns that have not been resolved through routine work processes.
Once your concern has been addressed, communicate any lessons learned to your staff, co-workers, supervisors and your Division Lessons Learned Coordinator. ES&H Manual Chapter 2310 offers more information on concern resolution.
