Any groundwater use in the county which has been approved as part of a county conditional use permit before the effective date of the ordinance codified in this division, shall be deemed, during compliance with and for the term of such conditional use permit, to be exempt from the permitting and reporting provisions of this division, and the payment of fees incidental to registration, permitting, and reporting.
(Prior code § 92201.03)
92201.04 - Definitions.¶
Unless otherwise indicated by their context, the terms defined in this section govern the interpretation of this division.
"Abandon" means the cessation or suspension of use of a facility for more than twelve (12) consecutive months, or such longer period of not more than twenty-four (24) consecutive months as the director may approve in writing. The user may apply for a longer period of up to twelve (12) months during the first twelve (12) months of cessation or suspension of use, and the application must be for good cause.
"Artificial recharge" means an increase in groundwater resulting from the application or addition of water to surface land, or through any other artificial process. Artificial recharge may be unintentional, i.e., not performed with the purpose of increasing groundwater. Artificial recharge may be intentional, i.e., performed with the purpose of increasing groundwater. If a substantial purpose of an artificial recharge activity is the increase of groundwater, then it is intentional artificial recharge.
"Artificial recharge facility" means any device or method used for the intentional artificial recharge of groundwater in the county.
"Available supply" means the quantity of groundwater which can be withdrawn annually from a groundwater basin without resulting in or aggravating conditions of overdraft, subsidence, groundwater quality degradation, or other environmental damage. Available supply of a groundwater basin includes the average annual natural water supply, imported water or other water which has been spread to the basin or otherwise added to the basin, and return flows to the basin attributable to these sources reaching the groundwater basin in the course of use.
"Close" means the ceasing of all use of a facility, and dismantling, capping, filling, or otherwise permanently modifying the facility in accordance with applicable building, mechanical or safety regulations, to prevent further use of the facility.
"Conditioning" or "to condition" means the treatment of water by chemical, mechanical, or other means, to improve or alter its quality or usefulness.
"Development project" means a project undertaken to develop property, including the development or expansion of agricultural uses, or involving the discretionary issuance to a person of a lease, building or other permit, license, certificate, or other entitlement for use granted by one or more public agencies, including, but not limited to any of the following:
A tentative map or tentative parcel map required by local ordinance or the Subdivision Map Act (commencing with Section 66410 of the Government Code of the state of California);
A conditional use permit;
A zone change;
A variance.
"Director" means the planning and development services director of the county.
"Export" means groundwater extracted for use outside the boundaries of the groundwater basin from which the groundwater is derived, or outside the county, or extracted groundwater used within the county in lieu of, and resulting in a reduction of, water previously within the county.
"Exportation facility" means any device or method used for the export of groundwater from the county or a groundwater basin within the county.
"Extraction" means the act of obtaining groundwater by pumping or other controlled means.
"Extraction facility" means any device or method for the extraction of groundwater within the county.
"Groundwater" means water which occurs in or moves, seeps, filters, or percolates through, or is located in the ground under the surface of the land, regardless of the source. "Groundwater" does not include any water which, on the effective date of the ordinance codified in this division, is subject to appropriation under Part 2 (commencing with Section 1200) of Division 2 of the Water Code of the state of California. The character of water as "groundwater" is not modified by extraction.
"Groundwater basin" means the groundwater basin or basins, or portions thereof, within the boundaries of the county and any sub-basins located therein.
"Notice to the public" means giving notice at least ten (10) days before the date of the hearing, of the date, time, and place of hearing, location of the properties affected, and the nature of the matter under consideration, by:
Publishing such notice once in a newspaper of largest circulation in the county;
By posting such notice at the Imperial county administration center;
By mailing a copy of such notice postage prepaid to persons who have requested notice. Such requests shall be made in writing, delivered to the director, and shall expire at the end of the calendar year in which they are received.
"Off-basin use" means the extraction of groundwater for use within the county which does not overlie the groundwater basin from which the groundwater is extracted.
"Operator" means the person who operates an extraction facility, exportation facility, or artificial recharge facility. "Operator" also means the person to whom the extraction facility, exportation facility, or artificial recharge facility is assessed by the county assessor or, if not separately assessed, the person who owns the land upon which an extraction facility, exportation facility or artificial recharge facility is located.
"Overdraft" means the condition of a groundwater basin where the average annual amount of water extracted exceeds the average annual supply of water to the basin plus any temporary surplus.
"Overlying use" means the extraction of groundwater for use on the extractor's land within the county which overlies the groundwater basin from which the groundwater is extracted.
"Person" includes any state or local government agency, private corporation, firm, partnership, individual, group of individuals, or, to the extent authorized by law, any federal agency.
"Planning commission" means the commission selected pursuant to Section 90103 et seq. (planning commissioners appointment; election; terms of office; divisions; chairman), of this division.
"Replenishment" means spreading water over a permeable area for the purpose of allowing it to percolate to the groundwater basin, or otherwise adding water to the groundwater basin which without such effort would not augment the groundwater supply.
"Supplemental water" means surface water or groundwater imported from outside the watershed or watersheds of a groundwater basin and flood waters that are conserved and saved within the watershed or watersheds which would otherwise have been lost or would not have reached the groundwater basin.
"Temporary surplus" means the amount of water that can be extracted from a groundwater basin without adversely affecting the available supply or groundwater quality of the groundwater basin, to provide storage space for natural recharge that would be lost during wet years if it could not be stored in the groundwater basin.
"Use" means any actual consumption or other beneficial use of a specific quantity of groundwater at a specific location.
"User" means any person using groundwater.
"Well interference" means a substantial water level decline in a short time period in a localized area caused by extraction.
