2. So What is the Current Status • The CFS Group in General, is in a Very Challenging Situation • The International Linear Collider is not a Federally Recognized or Department of Energy Funded Project • The State of Illinois is not Officially Engaged in the Effort • Funding Levels are Uncertain at this Time, and A Continuing Resolution for FY 08 is a Virtual Certainty • So There will be a Series of Iterations • Investigation, Design and Identification of Further Work Needed • Request for and Approval to Proceed • Repeat as Needed • There are Likely to be a Number of These Cycles or Iterations Before an Illinois/Fermilab Site (or any Other Site) is Officially Declared the United States ILC Candidate Site

3. What’s Next • In Spite of the Challenges, Work Must Proceed • Refinement of Criteria and Design • Cost Reduction and Value Engineering • Regional Interest Issues • Environmental • Subsurface and Geotechnical Investigation and Characterization • We Also need to Develop a Plan to Complete the Effort • Gain Enough Information to Identify an Alignment • Identify the Surface Presence Needed • Begin to Understand the Acquisition Strategies • Without • Overselling the Project • Unduly Antagonizing Local Communities and Residents • Promising Things we Have No Authority to Promise • Overselling the Project • Getting Too Far Ahead of Actual Project Approval, Much Less Any National or International Site Selection Process

4. The Plan • First the Environmental Process Must Begin • This Process is Likely to Constitute the Critical Path for US Site Selection • This Process is Outlined in the National Environmental Protection Act • We Can Begin by Identifying Land Use and Ownership Beyond the Fermilab site Boundaries • We Can Also Begin to Characterize General Aspects of the Areas Around Fermilab • We Can Identify Possible Brownfield Sites for Advantages in the LEED Process • A Good Portion of This Can be Accomplished Using Existing Public Information Available Through Information Sharing Agreements with Adjacent Counties • Once the Initial Investigation is Completed, a Potential Alignment can be Identified which will Give Specific Shaft Locations

5. The Plan cont. • Subsurface Investigation is a Little More Complicated • We Can Begin with Investigation on the Fermilab Site • Soil Borings Can be Completed • Geotechnical Data • Vibration Transfer and Stability Assessments Can be Made • Ground Water Information Can be Verified • While a Good Start, Eventually This Same Investigation Process Will Need to be Conducted along the Entire Alignment Chosen for the ILC Including the Proposed Upgrade to 1 Tev (~4 More Shafts and Extending 10 km in Each Direction)

6. The Posters • The Posters Presented Reflect Conceptual Ideas Based on the Criteria Developed to Date • No Specific Programming has been Completed for any Surface Buildings • Cryogenic Compressor Buildings are Based on the LHC/CERN Model • Electrical and Cooling Equipment are Representative and will Ultimately be Directly Proportional to the Electrical Needs of the ILC Project • Shaft/Surface Configuration will Require Compromise Between the Project needs and LandAvailabilitly

10. Topic for Tonight’s Discussion • Given This Background Information, • What is the Best Way to Proceed
