Unless the context otherwise requires, the following definitions govern the construction of this section:
"Active fault"shall mean a fault which surface displacement has occurred during Holocene time (about the last 11,000 years) and is associated with one or more of the following:
1. A recorded earthquake with surface rupture;
"Dam failure inundation areas"shall mean areas below a dam structure (i.e., reservoir dam, debris basin) which would be inundated by the flow of water from the impoundment created by the dam structure if it were to fail.
"Flood hazard areas"shall mean areas which are prone to inundation by floods having a 100-year return period, or by flash floods and debris flows resulting from major storm events.
"Hazardous waste"shall mean a waste, or combination of wastes, which because of its quantity, concentration, or physical, chemical, or infectious characteristics may either:
1. Cause or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness.
2. Pose a substantial present or potential hazard to human health or environment when improperly treated, stored, transported, or disposed of, or otherwise managed.
"Hazardous waste facility"shall mean any structure, other appurtenances, and improvements on the land, and all contiguous land, used for the treatment, transfer, storage, resource recovery, disposal, or recycling of hazardous waste.
"Hazardous waste facility project"shall mean a project undertaken for the purpose of siting and constructing a new hazardous waste facility or for the purposes of significantly expanding or modifying an existing hazardous waste facility that is being used or operated under a permit pursuant to Section
25200 of the California Health and Safety Code or a grant of interim status pursuant to Section 25200.5 of that code. Unless expressly provided otherwise, "hazardous waste facility project" includes a specified hazardous waste facility project.
"Hazardous waste land use decision"shall mean a discretionary decision of a local agency concerning a hazardous waste facility project, including the issuance of a land use permit or conditional use permit, the granting of a variance, the subdivision of property, and the modification of existing property lines pursuant to Title
7 (commencing with Section
65000) of the California Government Code.
"Immobile populations"shall mean facilities from which occupants should not or cannot be relocated. These include, but are not limited to, such uses as hospitals, nursing homes, child care facilities, K-12 schools, convalescent homes and jail facilities.
"Liquefaction"shall mean surface materials that develop liquid properties upon being disturbed.
"Potentially active fault"shall mean a fault showing evidence of surface displacement during Quaternary time (from the last 11,000 years to about the last two to three million years), and is characterized by the following:
2. Association with an alignment of numerous earthquake epicenters;
3. Continuity with faults having historic displacement;
4. Association with youthful major mountain scarps or ranges;
5. Correlation with strong geophysical anomalies.
"Proximity to populations"shall mean the distance from the active portion of the facility (where waste will be treated or stored) to dwellings used by one or more persons as a permanent place of residence, or to dwellings inhabited by persons temporarily for purposes of work (e.g., migrant workers, construction camps), or to dwellings used for temporary purposes (e.g., hotels or motels).
"Residuals repository"shall mean a specially sited, designed, constructed and operated facility for the purpose of storing waste residuals as a result of hazardous waste treatment.
"Significantly expand or modify"shall mean to expand or modify an existing hazardous waste facility, including a specified hazardous waste facility, in a manner so that a land use decision and environmental impact report are required.
"Slope stability"shall mean the relative degree to which the site will be vulnerable to the forces of gravity, such as landslide, soil creep, earth flow, or any other mass movement of earth material which might cause a breach, carry wastes away from the facility, or inundate the facility.
"Specified hazardous waste facility project"shall mean a project undertaken for the purpose of siting and constructing a new specified hazardous waste facility or for the purpose of significantly expanding or modifying an existing specified hazardous waste facility that is being used or operated under a permit issued pursuant to Section
25200 of the California Health and Safety Code or a grant of interim status pursuant to Section 25200.5 of that code.
"Subsidence"shall mean a sinking of the land surface following the removal of solid mineral matter or fluids (e.g., water or oil) from the subsurface.
