The "Rhode Island Clean Air Preservation Act" seeks to prohibit atmospheric interventions such as cloud seeding and solar radiation modification (SRM) that release pollutants, particularly Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS). The bill introduces a new chapter (CHAPTER 23.8) into Title 23 of the General Laws, defining key terms related to atmospheric activities and establishing a legal framework aimed at protecting public health and the environment from harmful geoengineering practices. The Rhode Island State Police (RISP) will serve as the regulatory authority, empowered to issue cease-and-desist orders and enforce penalties for violations, which may include felony charges and substantial fines.

In addition to prohibiting specific atmospheric experiments, the bill mandates that any irradiating infrastructure be evaluated by an independent licensed radiofrequency engineer, with strict signal strength limits. Facilities exceeding these limits will have 30 days to comply or face fines. The legislation also emphasizes the importance of secure communications through hardwired connections, reducing reliance on wireless systems. Notably, the bill deletes the previous mention of "weather modification" from the governor's emergency management powers, indicating a shift towards stricter regulation of atmospheric interventions. The act will take effect upon passage.
