Is the Navy required to investigate and remediate all confirmed releases from the Red Hill Facility, even those before the 2021 JP-5 releases?

Yes, as part of the closure process, the Navy is required to investigate and remediate all historical releases, including those that occurred prior to November 2021. The Navy is conducting site assessments and investigations to determine the location, nature, and extent of contamination, as well as develop a conceptual site model (a comprehensive representation of site environmental conditions with respect to recognized or potential environmental hazards). Regulators will continue to carefully evaluate data from the site assessments and investigations to help guide remediation.
