Creates the "Clear Skies Act" prohibiting geoengineering, cloud seeding and other atmospheric interventions, authorizing DNR to investigate violations, and includes penalty provisions
HB2656 creates the “Clean Skies Act” and adds a new section to Missouri’s environmental laws prohibiting geoengineering, weather modification, and cloud seeding in the state. The bill defines a wide range of terms related to atmospheric intervention, including aircraft, airports, pollutants, geoengineering, weather modification, and cloud seeding, and it specifically excludes ordinary aircraft contrails and certain farming and ranching activities unless they amount to cloud seeding.
The bill also directs the Department of Natural Resources to create a public online reporting form for suspected violations, investigate credible complaints, and refer confirmed violations to county prosecutors or the attorney general. It authorizes the department to work with local law enforcement, the State Highway Patrol, or the Missouri National Guard if needed, and it requires the department to promulgate rules identifying chemicals considered violations. The bill creates criminal penalties for violations, ranging from a class A misdemeanor for a first offense to a class E felony for repeat offenses, and a class C felony if serious physical injury or death results. It also creates a private right of action for harmed persons to seek damages, injunctive relief, attorney’s fees, and punitive damages.
The bill’s impact would be to expand chapter 640 of Missouri law with a new enforcement regime aimed at atmospheric modification activities. It would place new compliance and reporting obligations on aircraft owners and airport employees who are aware of equipment used for cloud seeding, geoengineering, or weather modification, and it would expose violators to both criminal and civil liability. It also gives the Department of Natural Resources a new investigative and rulemaking role in an area that currently appears to be regulated primarily through this proposed section.
The general sentiment reflected in the bill materials is supportive enough to advance in the House, as shown by the committee substitute being reported do pass, but there is no recorded floor vote or transcript in the provided materials to show broader debate. The bill’s framing suggests a strong policy preference for restricting atmospheric intervention, with an emphasis on enforcement and public reporting. Because no committee transcript is provided, there is no direct evidence of opposition or support from specific lawmakers or stakeholders in the available record.
The main points of contention likely center on the breadth and scientific basis of the definitions, the ban on geoengineering and weather modification, and the unusual reporting and enforcement structure. Potential concerns include whether the bill could affect legitimate aviation, agricultural, or environmental activities, whether the reporting requirements could lead to false accusations, and whether the Department of Natural Resources is the appropriate agency to police these activities. The bill itself anticipates false reporting by making it a misdemeanor, and it tries to limit scope by excluding contrails and some farming and ranching actions.
HB2656 would amend chapter 640, RSMo, by creating section 640.870 and establishing a new state prohibition on geoengineering, weather modification, and cloud seeding. It would also assign the Department of Natural Resources investigative and rulemaking authority, create criminal penalties and civil remedies, and impose reporting duties on certain airport and aircraft personnel, thereby affecting environmental regulation, aviation-related actors, and potential atmospheric intervention activities in Missouri.
The available legislative record suggests the bill was treated favorably enough in committee to receive a do-pass recommendation, indicating at least some support for the measure’s anti-geoengineering policy. However, there are no transcripts or roll-call votes provided, so the broader sentiment cannot be measured precisely. Based on the bill’s structure, the overall tone is precautionary and enforcement-oriented, with the legislature appearing concerned about atmospheric modification activities and public reporting of suspected violations.
Likely points of contention include the bill’s expansive definitions of geoengineering and pollutants, the outright ban on weather modification and cloud seeding, and the potential for overreach into aviation, agriculture, and environmental practices. Critics could question the scientific premise, the practicality of enforcement, and the risk of false reports, while supporters would likely emphasize environmental protection and transparency. The bill attempts to address some of these concerns by exempting contrails and certain farming and ranching activities and by penalizing false reports.
