A bill to amend the John D. Dingell, Jr. Conservation, Management, and Recreation Act to reauthorize the National Volcano Early Warning and Monitoring System, and for other purposes.

This bill reauthorizes and updates the National Volcano Early Warning and Monitoring System through the John D. Dingell Act. It increases annual funding from $55 million to $75 million, extends the program's authorization period to 2033-2034, and modernizes technical language (replacing "Global Positioning System" with "Global Navigation Satellite System"). Key provisions include requiring management plan updates every 5 years, creating a new implementation committee with state agencies, universities, and volcano observatories, and strengthening coordination with the Forest Service. The changes directly affect U.S. Geological Survey operations and volcano monitoring at active sites, improving early warning capabilities for communities near volcanoes.
