In California, the scenario described may fall under the purview of the California Environmental Quality Act (CEQA). CEQA requires state and local agencies to assess the environmental impact of their actions, including the potential effects on public health.
If the lack of air pollution monitoring leads to inadequate assessment or mitigation of air quality impacts, especially in a community experiencing health issues, it could be a CEQA concern.
Additionally, Assembly Bill 617 (Community Air Protection Program) specifically addresses air quality in communities burdened by pollution and may also be relevant in this situation. This law mandates increased monitoring and community engagement to reduce pollution exposure in affected areas.
