Item #9
RESOLUTION IN SUPPORT OF
THE BUTTE ENVIRONMENTAL COUNCIL INVOLVEMENT IN THE
SUSTAINABLE GROUNDWATER MANAGEMENTACT PROCESS
WHEREAS,the Sustainable Groundwater Management Act of 2014 ("SGMA") provides
local agencies (counties and cities with land-use authority and single and multipurpose special
districts with water management authority) with the directive and authority to manage
groundwater locally,with State oversight; and
WHEREAS, high and medium priority groundwater basins must develop and be
managed under a Groundwater Sustainability Plan (GSP), which must be submitted to the
California Department of Water Resources by January 31, 2022,for the subbasins within Butte
County; and
WHEREAS, one of the steps in that process in Butte County is for eligible local agencies
in each subbasin to determine the make-up of an inclusive governance structure in their
respective groundwater subbasin.The governance agencies, known as Groundwater
Sustainability Agencies (GSAs), can be a single entity managing an entire basin or subbasin or
multiple entities; and
WHEREAS, in many counties throughout the Central Valley of California, including Butte
County,which are subject to SGMA with high and medium priority sub-basins, there are tracts
of land known as"white areas," which are areas within counties that are not within the
boundaries of an otherwise eligible local agency; and
WHEREAS, pursuant to SGMA,these "white areas" may be covered and regulated by a c
ounty, or they may elect to annex through a Local Agency Formation Commission (LAFCo) proce
ss to an eligible local agency with SGMA authority, or petition LAFCo to form a new eligible local
agency under SGMA such as a California Water District (Water Code Sections 34000 et.al.); and
WHEREAS, Butte County is located within the Sacramento Valley Basin, and the State
has identified four sub-basins within the Sacramento Valley Basin per DWR's Bulletin 118,
partially located within Butte County: namely Vina, West Butte, East Butte, and Wyandotte
Creek; and
WHEREAS, Butte County began a collaborative process in 2015 with all eligible local
agencies to reach consensus within the County on principles of GSA formation and future SGMA
governance.The goal of this process is to define a set of working principles that are shared
among eligible local agencies and that consistently and constructively shape SGMA interaction
and decision-making; and
WHEREAS,those principles include the following:
1. Maximize value of familiar structures and relationships;
2. Acknowledge all key interests of eligible local agencies;
3. Respect legally recognized rights;
4. Anticipate GSA requirements;
5. Make use of basin boundary adjustments;
6. Comply with SGMA regulations;
7. Identify opportunities to address interests of current non-GSA stakeholders;
8. Distribute costs in an equitable manner as possible;
9. Respect mutual interests in maintaining independent decision-making; and
WHEREAS, the "white areas" of Butte County within the four sub-basins are not
represented by other eligible local agencies and will therefore be represented by Butte County
unless these areas choose to annex to an eligible local agency or form a new one; and
WHEREAS, Butte Environmental Council (BEC) as a local non-profit engaged in Butte County
water advocacy since 1975 has taken an active role in the collaborative SGMA process since it
began in 2015 and continues to engage in all aspects of SGMA implementation and governance.
Butte Environmental Council is uniquely positioned to represent key interests in SGMA and
supports the interests of beneficial users of groundwater including domestic groundwater
users, and the environment in decision making processes; and;
WHEREAS,the Butte Environmental Council recognizes and respects the leadership of Butte
County and it its efforts to create a workable and cooperative structure to discuss GSP; and
WHEREAS,the Butte Environmental Council recognizes and respects the leadership of Butte
County to move forward to complete a comprehensive GSP by January 31, 2022; and
WHEREAS, inherent in this process and timeframe Butte County will endeavor through the
stakeholder process to develop a governance structure,for SGMA oversight of each of the four
subbasins within Butte County consistent with the nine principles enumerated above; and
WHEREAS, principle number 7 above, recognizes that the interests of non-GSA stakeholders
such as domestic pumpers, and the environment should be addressed; and
WHEREAS, Butte County recognizes the value of input and participation in the SGMA
process by the Butte Environmental Council, which has been committed to protecting and
defending the land, air and water of Butte County through action, education and advocacy
since 1975, and is comprised of more than 600 community members dedicated to our local
environment.
NOW,THEREFORE, BE IT RESOLVED:
1. The County of Butte will continue to work with stakeholders within Butte County
utilizing a collaborative process to establish a governance structure and
ultimately develop a Groundwater Sustainability Plan, and the Butte
Environmental Council will openly and earnestly participate and cooperate in
that process as a representative for the environment at large.
2. As governance structures for implementation of SGMA are discussed among, and
ultimately decided by all eligible local agencies within the four subbasins, the
County of Butte and the Butte Environmental Council will work together to
advocate for and implement governance structures in each subbasin that will
recognize and allow for appropriate representation of domestic pumpers, and
the environment at large within each governance structure in compliance with
SGMA.

I Item #10
{ Management Areas
§ 357.. Definitions
(r) "Management area" refers to an area within a basin for which the Plan may
identify different minimum thresholds, measurable objectives, monitoring, or
projects and management actions based on differences in water use sector, water
source type, geology, aquifer characteristics, or other factors.
§ 354.20. Management Areas
(a) Each Agency may define one or more management areas within a basin if the
Agency has determined that.creation of management areas will facilitate
implementation of the Plan. Management areas may define different minimum
thresholds and be operated to different measurable objectives than the basin at
large, provided that undesirable results are defined consistently throughout the
basin.
(b) A basin that includes one or more management areas shall describe the following in
the Plan:
(1) The reason for the creation of each management area.
(2) The minimum thresholds and measurable objectives established for each
management area, and an explanation of the rationale for selecting those values,
if different from the basin at large.
(3) The level of monitoring and analysis appropriate for each management area.
(4) An explanation of how the management area can operate under different
minimum thresholds and measurable objectives without causing undesirable
results outside the management area, if applicable.
(c) If a Plan includes one or more management areas, the Plan shall include
descriptions, maps, and other information required by this Subarticle sufficient to
describe conditions in those areas.
§ 354.34. Monitoring Network
(d) The monitoring network shall be designed to ensure adequate coverage of
sustainability indicators. If management areas are established, the quantity and
density of monitoring sites in those areas shall be sufficient to evaluate conditions of
the basin setting and sustainable management criteria specific to that area.
§ 356.4. Periodic Evaluation by Agency
(c) Elements of the Plan, including the basin setting, management areas, or the
identification of undesirable results and the setting of minimum thresholds and
measurable objectives, shall be reconsidered and revisions proposed, if necessary.
