Washington : 2025-2026 Regular Session : BILL HB2222
Restricting weather modification activities.
Sponsor: Rep Rob Chase
Bill Details
Restricting weather modification activities.
Bill summary
This bill prohibits injecting, releasing, or dispersing any chemical, substance, or apparatus into Washington's atmosphere or hydrological systems to affect temperature, weather, climate, or sunlight intensity.
The bill bans activities such as stratospheric aerosol injections and the manipulation of the atmosphere at different levels. It also bans cloud seeding, so-called "chemtrail events," and weather modification using aircraft, weather balloons, drones, or satellites. Ground-based tools like radar, 5G, 6G, RF waves, and lasers are also prohibited. Additionally, it forbids spreading or energising nano particles over people in Washington.
Breaking these rules can lead to felony charges. A first violation is a Class C felony with fines up to $1,000,000. Repeat violations become a Class B felony. Aircraft operators face separate penalties. A first offence means a $5,000 fine and up to five years in prison. Repeat offences mean a $5,000 fine and up to ten years in prison. Each violation counts separately. All fines go into the air pollution control account.
The Department of Ecology will set up an online system for people to report complaints. This system will include an email address and a web form. The department must look into valid reports. It can send cases to the Department of Health or the Emergency Management Division if needed.
Starting October 1, 2026, all airport operators must report monthly to the Department of Transportation. Reports must list any aircraft equipped for atmospheric modification at their public facilities. Airports that do not comply lose state funding.
Anyone can sue people they believe are breaking the law. They can also force the department to investigate or sue it if it does not do its job. Courts can award attorney's fees and expert witness costs to the prevailing party.
The bill repeals Washington’s weather modification rules (RCW 70A.10). These rules established a licensing and permit system in 1965. This means the state will no longer supervise or regulate weather modification.
An unusual aspect of the bill is the use of the word "chemtrail" in the law. It also bans 5G, 6G, radar, and RF waves as methods of weather modification. The bill mentions "energizing" nanoparticles and ends the current regulatory system rather than changing it.
History
HB 2222 was prefiled on December 31, 2025, by Representative Chase for consideration during Washington's 2026 Regular Session. Prefiling is a procedural mechanism that allows legislators to submit bills before the session officially convenes. Washington's 2026 session begins January 12, 2026, and runs through approximately March 12, 2026. The bill has not yet been formally introduced or assigned to a committee.
Washington operates on a biennial legislative cycle beginning in odd-numbered years, with the 2026 session representing the second year of the 69th Legislature. Bills prefiled in December are queued for processing once the session opens. As a House bill, HB 2222 will first need committee assignment after introduction, followed by committee hearings and votes, before proceeding to the House floor and then the Senate for identical consideration.
