To amend the John D. Dingell, Jr. Conservation, Management, and Recreation Act to reauthorize the National Volcano Early Warning and Monitoring System.

This provision makes two key changes to Section 5001(c)(1) of the John D. Dingell, Jr. Conservation, Management, and Recreation Act. First, it changes the administering entity for a component of the National Volcano Early Warning and Monitoring System from the "United States Geological Survey" to the broader term "Secretary," implying the Secretary of the Interior. Second, it extends the authorization period for this specific part of the system from fiscal years 2019 through 2023 to fiscal years 2026 through 2029. This reauthorization ensures the continued operation and funding eligibility for this critical volcano monitoring program.

This provision amends Section 5001(c)(2) of the John D. Dingell, Jr. Conservation, Management, and Recreation Act. It changes the administering entity for another component of the National Volcano Early Warning and Monitoring System from the "National Oceanic and Atmospheric Administration" to the "Secretary of Commerce." Crucially, it replaces the previous open-ended authorization of "such sums as may be necessary" with a specific appropriation of "$470,000 for each of fiscal years 2026 through 2029." This provides a clear, fixed funding level for this part of the system, allowing for more predictable program planning.
