The ordinance codified in this chapter may be cited as the "Groundwater
Mining and Export Ordinance of Merced County."
(Ord. 2014 § 1, 2022)
The Merced County board of supervisors makes the following findings
in support of the enactment of the ordinance codified in this chapter:
1. The
protection of the health, welfare, and safety of the residents of
the county require that the groundwater resources of Merced County
be protected from adverse impacts resulting from both the mining of
groundwater resources and the export of those resources outside each
respective county groundwater basin; and
2. Groundwater
is an essential resource for continued agricultural production within
the county which production includes, but is not limited to, field
crops, nut and fruit crops, vegetable crops, seed crops, poultry and
livestock and products which significantly contribute to the gross
value of the total agricultural production of the county, state, and
nation; and
3. Groundwater
is an essential resource for agricultural, municipal, industrial,
and domestic uses within the county; and
4. The
mining of groundwater resources from within the county and the export
of groundwater from inside Merced County to outside of the respective
groundwater basin in which it originates will each have adverse environmental
impacts on the county, including, but not limited to, the following:
increased groundwater overdraft, land subsidence, uncontrolled movement
of inferior quality groundwater, the lowering of groundwater levels,
increased groundwater degradation, streamflow depletion and depleted
groundwater basins; and
5. The
mining of groundwater resources from within the county and the export
of groundwater from inside Merced County to outside of the respective
groundwater basin in which it originates will each have adverse economic
impacts on the county, including, but not limited to the following:
loss of arable land, a decline in property values, increased pumping
costs due to the lowering of groundwater levels, increased groundwater
quality treatment costs, replacement of wells due to declining groundwater
levels, losses due to flooding and inundation, and replacement of
damaged wells, conveyance infrastructure, roads, bridges and other
appurtenances, structures or facilities due to land subsidence; and
6. The
effects of the mining of groundwater resources from within the county
and the export of county groundwater from inside Merced County to
outside of the respective groundwater basin in which it originates,
compounded by persistent drought conditions, presents urgent problems,
including the following: subsidence of groundwater aquifer systems,
weakening of proprietary groundwater rights, interruption of utility
and transportation services provided by infrastructure, placing drinking
water supplies at risk, decreasing the county's range land grasses
for feed, reducing crop irrigation supplies to critical levels, increasing
unemployment and economic hardship in the county because of a reduction
of agricultural jobs, failing to conserve groundwater supplies for
future years, and threatening harm to animals and plants that rely
on Merced County's lakes, rivers, streams, and wetlands; and
7. Climate
change has intensified the impacts of droughts in Merced County and
the state of California. Unpredictable surface water availability,
low moisture content in vegetation, and parched soils have magnified
the impact of regularly occurring drought. The 2021 water year was
the second driest in state history, and on October 19, 2021, the Governor
of California issued a proclamation declaring a state of emergency
due to statewide drought, which was sustained and worsened by extreme
high temperatures; and
8. Based
on the foregoing facts, continued action to address groundwater mining
and extraction is necessary for the preservation of health, safety,
and well-being of Merced County's citizens, economy, agricultural
resources, and environmental resources. Excessive groundwater extraction
threatens Merced County's drinking water supplies and has caused land
subsidence that threatens Merced County's roads, bridges, water conveyance,
and flood and inundation management infrastructure; and
9. California
Constitution, Article X, Section 2, and
Water Code Section 100 prohibit
the waste, unreasonable use, unreasonable method of use, and unreasonable
method of diversion of water. The county finds that, under current
drought and aquifer conditions, the export of groundwater for use
outside the respective groundwater basins within the county in which
it originates is a presumptively unsustainable use of groundwater
and not reasonable or beneficial within the meaning of the California
Constitution and the California
Water Code; and
10. The
risks to health, safety and well-being in Merced County from the mining
and export of groundwater require the county to take actions to support
the implementation of the Sustainable Groundwater Management Act (SGMA),
which recognizes and preserves the authority of cities and counties
to manage groundwater pursuant to their police powers.
(Ord. 2014 § 1, 2022)
The following words and phrases shall have the following meanings
when used in this chapter:
"Basin"
means any one of the following sub-basins of the San Joaquin
Valley Basin [5-22], as identified in Department of Water Resources
Bulletin 118:
Turlock [5-22.03]
|
Merced [5-22.04]
|
Chowchilla [5-22.05]
|
Delta Mendota [5-22.07]
|
"Board"
means the board of supervisors of Merced County.
"Export of groundwater"
means the extraction of groundwater from any well for other
than municipal use within the boundaries of Merced County and located
on or under parcels subject to this chapter and conveyed to, or used
directly or indirectly on parcels which are outside of the boundaries
of the Merced County groundwater basin from which the groundwater
is extracted. Export of groundwater includes activities by which groundwater
may through one or more exchanges or transactions be directly or indirectly
conveyed or transferred for use out of the same basin from which it
is extracted.
"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, but does not include water that flows in known and definite
channels.
"Mining"
means the process, deliberate or inadvertent, of extracting
groundwater from a source at a rate or amount in excess of the replenishment
rate, such that the groundwater level declines persistently, threatening
exhaustion of the supply, a decline of pumping levels to uneconomic
depths, land subsidence, or significant water quality or other significant
environmental damage.
"Person"
means and includes natural persons, corporations, firms,
partnerships, joint stock companies, associations and other organizations
of persons, and public entities.
"Public water agency"
means any local public agency, mutual water company, or nonprofit
tax-exempt unincorporated association within, or partially within,
Merced County that has authority to extract, deliver, store, or regulate
water.
(Ord. 2014 § 1, 2022)
The following actions are prohibited unless allowed under an
exemption or permit as set forth in this chapter:
A. Groundwater
mining, as defined in this chapter, within the unincorporated areas
of the county. This provision shall prohibit the construction of wells.
B. The
export of groundwater from inside Merced County outside of the respective
groundwater basin in which it originates.
(Ord. 2014 § 1, 2022)
All permits granted for wells or groundwater exports under the scope of this chapter shall be conditioned on the installation and proper maintenance of a water measuring device acceptable to the division of environmental health. As an alternative to water measuring devices, other reasonable methods to determine groundwater extraction may be used if approved by the division of environmental health. This requirement shall not apply to well construction done under the exemptions stated in subsections
B and
C of Section
9.27.050 of this chapter.
