Prohibiting solar radiation modification, weather modification, and other polluting atmospheric interventions.

Impact

The enactment of HB 1618 would significantly reshape the legal landscape surrounding atmospheric experimentation in New Hampshire. The bill outlines penalties for violations, including fines and potential imprisonment for individuals or entities engaging in any illegal atmospheric interventions. Furthermore, the DES anticipates implementing procedures for inspections and compliance monitoring, indicating a shift towards a more regulated approach to environmental protection in the state. The bill suggests a proactive stance in managing air quality and mitigating pollution from experimental activities.

Summary

House Bill 1618, titled 'The Clean Air Preservation Act', seeks to prohibit solar radiation modification (SRM), geoengineering, and other atmospheric interventions that could involve the release of pollutants within the state of New Hampshire. The bill repeals and reenacts RSA 12-F, aiming to establish a regulatory framework to prevent activities that may alter weather patterns and affect environmental health negatively. By assigning enforcement responsibilities to local county sheriffs and the Department of Environmental Services (DES), the bill intends to ensure compliance with these prohibitions to protect natural resources and public health.

Sentiment

The sentiment surrounding HB 1618 appears to be largely supportive among environmental advocacy groups and individuals concerned about the potential risks of atmospheric modification technologies. Proponents emphasize the need for strict regulations to safeguard public health and ecological integrity. However, there may be contention from sectors that view such prohibitions as restrictive, particularly those involved in research or innovations that seek to address climate change through geoengineering practices.

Contention

Notable points of contention within discussions of HB 1618 include concerns over the feasibility of enforcing compliance and the adequacy of funding for necessary regulatory positions. The bill does not authorize new funding, which may complicate implementation. Additionally, there are apprehensions about the bill's potential impact on legitimate scientific research, given the broad definitions of prohibited activities. The lack of clarity in the bill regarding what constitutes pollutants and atmospheric interventions poses challenges for consistent enforcement and legal interpretation.
