Section 37900 Of Chapter 1. General Provisions From California Water Code >> Division 13. >> Part 8.2. >> Chapter 1.
37900
. (a) For purposes of this part, the following definitions
apply:
(1) "Aquifer" means a geologic formation or structure that
transmits water in sufficient quantities to supply pumping wells or
springs.
(2) "Available supply" means that quantity of groundwater that can
be withdrawn in any given year from a groundwater basin or aquifer
without resulting in or aggravating conditions of overdraft,
subsidence, or groundwater quality degradation. Available supply of a
groundwater basin or aquifer includes the natural water supply,
imported water, or other water that has been spread to a basin or
aquifer or otherwise added to a basin or aquifer, and return flows to
the basin or aquifer attributable to these sources reaching the
groundwater basin or aquifers in the course of use.
(3) "Board" means the board of directors of the Paso Robles Basin
Water District.
(4) "Conjunctive use" means the coordinated operation of a
groundwater basin and groundwater and surface water supplies.
Conjunctive use includes increased groundwater use or decreased
groundwater replenishment with surface supplies in years when surface
supplies are less than normal and, in years of more abundant surface
supplies, the increased use of surface water in lieu of groundwater,
either to allow groundwater levels to recover or to replenish
artificial groundwater supplies. Conjunctive use also includes
long-term storage of water in a groundwater basin.
(5) "County" means the County of San Luis Obispo.
(6) "District" means the Paso Robles Basin Water District, the
boundaries of which shall be established and may be modified by the
San Luis Obispo County Local Agency Formation Commission.
(7) "Excess extractions" means those extractions in excess of an
operator's extraction allocation or adjusted extraction allocation.
(8) "Extraction" means the act of obtaining groundwater by pumping
or other controlled means.
(9) "Extraction allocation" means the amount of groundwater that
may be extracted from an extraction facility during a calendar year
before a surcharge is imposed.
(10) "Extraction surcharge" means a surcharge assessed annually
each time an operator exceeds his or her extraction allocation.
(11) "Extraction facility" means any device or method for the
extraction of groundwater within a groundwater basin or aquifer.
(12) "Groundwater" means water beneath the surface of the earth
within the zone below the water table in which the soil is completely
saturated with water.
(13) "Groundwater basin" means a geologically and hydrologically
defined area containing one or more aquifers that store and transmit
water yielding significant quantities of water to wells.
(14) "Groundwater management activities" means programs, measures,
or actions taken to preserve, protect, and enhance groundwater
resources within the territory of the district.
(15) "Groundwater rights adjudication" means the determination of
substantially all rights in a groundwater basin or the area subject
to the adjudication.
(16) "Operator" means a person who operates a groundwater
extraction facility. In the event the district is unable to determine
who operates a particular extraction facility, then "operator" shall
mean the person to whom the extraction facility is assessed by the
county assessor or, if not separately assessed, the person who owns
the land upon which the extraction facility is located.
(17) "Overdraft" means the condition of the groundwater basin or
aquifer where the average annual amount of water extracted exceeds
the average annual supply of water to a basin or aquifer.
(18) "Program" means a groundwater management program prepared by
the district pursuant to this act.
(19) "Recharge" means the natural or artificial replenishment of
groundwater storage by percolation or injection of one or more
sources of water at the surface.
(20) "Replenishment" means spreading water over a permeable area
for the purpose of allowing it to percolate to groundwater basins or
aquifers, or otherwise adding water to groundwater basins or
aquifers.
(21) "Safe yield" means the condition of a groundwater basin when
the total average annual groundwater extractions are equal to, or
less than, the total average annual groundwater recharge, either
naturally or artificially.
(22) "Supplemental water" means surface water or groundwater
imported from outside the watershed or watersheds of the groundwater
basin or aquifer and floodwaters that are conserved and saved within
the watershed or watersheds that would otherwise have been lost or
would not have reached the groundwater basin or aquifers.
(23) "Well interference" means a substantial water level decline
in a short time period in a localized area caused by pumping from
extraction facilities.
(b) This part shall apply only to the Paso Robles Basin Water
District.
