CA AB1981

Amends Section 21082.2 of the Public Resources Code to clarify that lead agencies must determine whether a project may have a significant environmental effect based on substantial evidence in light of the whole record.

Specifies that public controversy over environmental effects alone does not require preparation of an environmental impact report without substantial evidence of significant environmental impact.

Defines what does not constitute substantial evidence, including speculation, unsubstantiated opinion, clearly inaccurate evidence, and social or economic impacts unrelated to physical environmental effects.

Clarifies that substantial evidence includes facts, reasonable assumptions based on facts, and expert opinion supported by facts.

Makes nonsubstantive grammatical and clarifying edits to existing CEQA provisions regarding environmental impact report preparation requirements.
