| FY 2025 | October 1, 2024 | None | |
| FY 2024 | October 1, 2023 | None | |
| FY 2023 | October 1, 2022 | Clarifications and updates were made for the Atmospheric Radiation Measurement (ARM) User Facility, Environmental Molecular Sciences Laboratory (EMSL), and Joint Genome Institute (JGI). | |
| FY 2022 | October 1, 2021 | Accelerator Test Facility is now stewarded by the Office of Accelerator R&D and Production. The Facility for Rare Isotope Beams (FRIB) was added to the list of Nuclear Physics facilities. |
|
| FY 2021 | October 1, 2021 | Posted retroactively to document changes in remote user counting practices necessitated by the COVID-19 pandemic for the Basic Energy Sciences user facilities. The Facility for Advanced Accelerator Experimental Tests (FACET) was upgraded and is now called the Facility for Advanced Accelerator Experimental Tests II (FACET-II). This change is effective as of the start of FY 2020. |
|
| FY 2020 | May 18, 2020 | Clarifications and updates were made for the Environmental Molecular Sciences Laboratory (EMSL) user facility | |
| FY 2019 | November 15, 2019 | The High Energy Physics Accelerator Test Facility (ATF) was added to the list of Office of Science user facilities, and the Fusion Energy Sciences facility Alcator C-Mod was removed. Several user facilities also have added clarifications for remote and data users. | |
| FY 2015 | October 1, 2014 | The three Basic Energy Sciences Electron Beam Microcharacterization Centers at ANL, LBNL, and ORNL were administratively merged with their respective neighboring Nanoscale Science Research Centers. | |
