Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Consistent with the State's interest in groundwater
						sustainability through local management, the following general principles shall
						guide the Department in the implementation of these regulations.
(a) Groundwater conditions must be adequately
					 defined and monitored to demonstrate that a Plan is achieving the
					 sustainability goal for the basin, and the Department will evaluate the level
					 of detail provided considering the basin setting.
(b) To comply with the Department's statutory
					 mandate to evaluate Plans, Plan implementation, and the effect on Plan
					 implementation on adjacent basins, Plan content information must be
					 sufficiently detailed and readily comparable.
(c) The Department shall evaluate the
					 adequacy of all Plans, including subsequent modifications to Plans, and reports
					 and periodic evaluations based on a substantial compliance standard as
					 described in Article 6, provided that the objectives of the Act are
					 satisfied.
(d) Sustainable
					 management criteria and projects and management actions shall be commensurate
					 with the level of understanding of the basin setting, based on the level of
					 uncertainty and data gaps, as reflected in the Plan.
(e) An Agency shall have the responsibility
					 for adopting a Plan that defines the basin setting and establishes criteria
					 that will maintain or achieve sustainable groundwater management, and the
					 Department shall have the ongoing responsibility to evaluate the adequacy of
					 that Plan and the success of its implementation.
(f) A Plan will be evaluated, and its
					 implementation assessed, consistent with the objective that a basin be
					 sustainably managed within 20 years of Plan implementation without adversely
					 affecting the ability of an adjacent basin to implement its Plan or achieve and
					 maintain its sustainability goal over the planning and implementation
					 horizon.
(g) The Department shall
					 consider the state policy regarding the human right to water when implementing
					 these regulations.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Each Agency shall describe in its Plan the processes and criteria relied upon
						to define undesirable results applicable to the basin. Undesirable results
						occur when significant and unreasonable effects for any of the sustainability
						indicators are caused by groundwater conditions occurring throughout the
						basin.
(b) The description of
						undesirable results shall include the following:
(1) The cause of groundwater conditions
						occurring throughout the basin that would lead to or has led to undesirable
						results based on information described in the basin setting, and other data or
						models as appropriate.
(2) The
						criteria used to define when and where the effects of the groundwater
						conditions cause undesirable results for each applicable sustainability
						indicator. The criteria shall be based on a quantitative description of the
						combination of minimum threshold exceedances that cause significant and
						unreasonable effects in the basin.
(3) Potential effects on the beneficial uses
						and users of groundwater, on land uses and property interests, and other
						potential effects that may occur or are occurring from undesirable
						results.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Each Agency in its Plan shall establish minimum thresholds that quantify
						groundwater conditions for each applicable sustainability indicator at each
						monitoring site or representative monitoring site established pursuant to
						Section 354.36. The numeric value used to
						define minimum thresholds shall represent a point in the basin that, if
						exceeded, may cause undesirable results as described in Section
						354.26.
(b) The description of minimum thresholds
						shall include the following:
(1) The
						information and criteria relied upon to establish and justify the minimum
						thresholds for each sustainability indicator. The justification for the minimum
						threshold shall be supported by information provided in the basin setting, and
						other data or models as appropriate, and qualified by uncertainty in the
						understanding of the basin setting.
(2) The relationship between the minimum
						thresholds for each sustainability indicator, including an explanation of how
						the Agency has determined that basin conditions at each minimum threshold will
						avoid undesirable results for each of the sustainability indicators.
(3) How minimum thresholds have been selected
						to avoid causing undesirable results in adjacent basins or affecting the
						ability of adjacent basins to achieve sustainability goals.
(4) How minimum thresholds may affect the
						interests of beneficial uses and users of groundwater or land uses and property
						interests.
(5) How state, federal,
						or local standards relate to the relevant sustainability indicator. If the
						minimum threshold differs from other regulatory standards, the Agency shall
						explain the nature of and basis for the difference.
(6) How each minimum threshold will be
						quantitatively measured, consistent with the monitoring network requirements
						described in Subarticle 4.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Each Agency shall establish measurable objectives, including interim milestones
						in increments of five years, to achieve the sustainability goal for the basin
						within 20 years of Plan implementation and to continue to sustainably manage
						the groundwater basin over the planning and implementation horizon.
(b) Measurable objectives shall be
						established for each sustainability indicator, based on quantitative values
						using the same metrics and monitoring sites as are used to define the minimum
						thresholds.
(c) Measurable
						objectives shall provide a reasonable margin of operational flexibility under
						adverse conditions which shall take into consideration components such as
						historical water budgets, seasonal and long-term trends, and periods of
						drought, and be commensurate with levels of uncertainty.
(d) An Agency may establish a representative
						measurable objective for groundwater elevation to serve as the value for
						multiple sustainability indicators where the Agency can demonstrate that the
						representative value is a reasonable proxy for multiple individual measurable
						objectives as supported by adequate evidence.
(e) Each Plan shall describe a reasonable
						path to achieve the sustainability goal for the basin within 20 years of Plan
						implementation, including a description of interim milestones for each relevant
						sustainability indicator, using the same metric as the measurable objective, in
						increments of five years. The description shall explain how the Plan is likely
						to maintain sustainable groundwater management over the planning and
						implementation horizon.
(f) Each
						Plan may include measurable objectives and interim milestones for additional
						Plan elements described in Water Code Section
						10727.4 where
						the Agency determines such measures are appropriate for sustainable groundwater
						management in the basin.
(g) An
						Agency may establish measurable objectives that exceed the reasonable margin of
						operational flexibility for the purpose of improving overall conditions in the
						basin, but failure to achieve those objectives shall not be grounds for a
						finding of inadequacy of the Plan.
