Unless the context otherwise requires, the definitions in this chapter govern the construction of this division.

“Emergency” means a sudden, unexpected occurrence, involving a clear and imminent danger, demanding immediate action to prevent or mitigate loss of, or damage to, life, health, property, or essential public services. “Emergency” includes such occurrences as fire, flood, earthquake, or other soil or geologic movements, as well as such occurrences as riot, accident, or sabotage.

“Environmental impact report” means a detailed statement setting forth the matters specified in Sections 21100 and 21100.1; provided that information or data which is relevant to such a statement and is a matter of public record or is generally available to the public need not be repeated in its entirety in such statement, but may be specifically cited as the source for conclusions stated therein; and provided further that such information or data shall be briefly described, that its relationship to the environmental impact report shall be indicated, and that the source thereof shall be reasonably available for inspection at a public place or public building. An environmental impact report also includes any comments which are obtained pursuant to Section 21104 or 21153, or which are required to be obtained pursuant to this division.

An environmental impact report is an informational document which, when its preparation is required by this division, shall be considered by every public agency prior to its approval or disapproval of a project. The purpose of an environmental impact report is to provide public agencies and the public in general with detailed information about the effect which a proposed project is likely to have on the environment; to list ways in which the significant effects of such a project might be minimized; and to indicate alternatives to such a project.

In order to facilitate the use of environmental impact reports, public agencies shall require that such reports contain an index or table of contents and a summary. Failure to include such index, table of contents, or summary shall not constitute a cause of action pursuant to Section 21167.

“Feasible” means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social, and technological factors.

“Major transit stop” means a site containing any of the following:

“Mitigated negative declaration” means a negative declaration prepared for a project when the initial study has identified potentially significant effects on the environment, but (1) revisions in the project plans or proposals made by, or agreed to by, the applicant before the proposed negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur, and (2) there is no substantial evidence in light of the whole record before the public agency that the project, as revised, may have a significant effect on the environment.

“Oil and gas infrastructure” means a facility used for the production, processing, transmission, storage, or distribution of petroleum or natural gas.
