Final answer:
The projects least likely to be subject to CEQA requirements are those with minimal environmental impact. Projects like toxic dumps are subject to CEQA due to potential significant environmental effects and their association with environmental racism.
Step-by-step explanation:
The California Environmental Quality Act (CEQA) requires state and local agencies to evaluate the environmental impacts of their proposed projects, with the goal of preventing or mitigating adverse effects on the environment. Projects that are least likely to be subject to CEQA requirements are those that do not have the potential to cause a significant effect on the environment, such as minor modifications to existing facilities or maintenance activities. On the other hand, projects often associated with environmental racism, such as toxic dumps or other objectionable projects, are more likely to require a thorough environmental review under CEQA because they can disproportionately affect disadvantaged communities.
