Federal Budget
• FY15 President’s Budget Request supports ~ 20 weeks running
• House Markup supports increase to ~ 27 weeks running
• Senate Markup supports increase to ~ 30 weeks running
• ONP has also encouraged us in our efforts to run for commissioning and
physics
• In turn, we are pleased by this recognition of our need, support from
users was important
Have started FY15 with a Continuing Resolution -> uncertainties
The way the cards fell our continuing resolution is at the President’s
Budget Request level
We are ensuring Fall Running
Hope for an appropriation at the Senate Level or somewhere
between the House and the Senate???

Commonwealth of Virginia Funding
Special Request $4.6M in the FY15 - FY16 biennium to help
improve Virginia’s competitive position for the Electron Ion
Collider:
• $1.3M in FY15 to initiate the site studies; $2.4M in FY16 to
complete the site studies
• $0.4M in FY15 and $0.5M in FY16 to attract a leading scientist
to Virginia
Virginia decided to fund no new initiatives in higher education
We have met with the Department of Planning and Budgets,
Secretary of Commerce, and representative of Secretary of
Education in the past few weeks to try to get into this years mix.
Annual Funding
• We are to reduce the Virginia funding for FY15 by 5% and for FY16 by 7%
