Dear Mr. Remien:

SUBJECT:

NATIONAL ENVIRONMENTAL POLICY ACT EVALUATION OF

RAPID CYCLING SYNCHROTRON/LINAC COMPLEX FOR

ELECTRON ION COLLIDER

Reference:

Letter from J. Remien, BSA to C. Polanish, SC-BHO, Subject: NEPA Environmental Evaluation Notification Form – Rapid Cycling Synchrotron/LINAC Complex for EIC, dated March 11, 2025 Letter from J. Remien, BSA to C. Polanish, SC-BHSO, Subject: NEPA Supplemental Information – Rapid Cycling Synchrotron/LINAC Complex for Electron Ion Collider (EIC), dated May 22, 2025

Following the Department of Energy (DOE) Guidance on Recommendations for the Supplement Analysis Process (January 2019), DOE performed a supplement-like analysis based on the information provided in the above-referenced letters, the Environmental Assessment for the Construction and Operation of the Electron-Ion Collider at Brookhaven National Laboratory (DOE/EA-2138), and the associated Finding of No Significant Impact (FONSI). As a result of the analysis, DOE found that the changes in potential environmental impacts from the proposed modifications are negligible. Therefore, I have determined that no further NEPA review for this project is needed. If you should have any questions, please contact Kathleen Green at extension 4089. Sincerely,

Craig R.
