10/21/2025 Institutional Control Periodic Reporting REPORT APPROVAL: DEC approved the 2024 Institutional Controls Inspection Report, which documents site inspections conducted between August 15–30, 2024. While the report is approved, DEC has noted several observations for documentation, including references to RCRA status, environmental release reporting, SWMU 1 and SWMU 20. These observations do not affect the approval of the ICIR but may warrant further evaluation during the upcoming Five-Year Review. DEC continues to coordinate with the Navy to ensure long-term protectiveness of institutional controls at the Adak site. Jamie McKellar
