The District is divided into three Regulatory Areas. This Regulatory Plan sets out a schedule for regulating groundwater withdrawal for each of the three Regulatory Areas. Specific Regulatory Area requirements are in addition to the general element requirements.

Regulatory Area 1

Groundwater withdrawals for each permittee must comprise no more than 10% of the permittee’s annual total water demand.

A disincentive fee will be applied to any groundwater allocation that constitutes greater than 10% of the permittee’s total water demand.

Regulatory Area 2

Groundwater withdrawals for each permittee must comprise no more than 20% of the permittee’s annual total water demand.

A disincentive fee will be applied to any groundwater allocation that constitutes greater than 20% of the permittee’s total water demand.

Regulatory Area 3

Groundwater withdrawals must compromise no more than 20% of the permittee’s annual total water demand, unless the permittee is operating under a certified groundwater reduction plan (GRP). A permittee operating under a certified GRP must maintain their groundwater withdrawals to comprise no more than 70% of the permittee’s total water demand through 2025. Beginning with permits issued in 2025, permittees operating under a certified GRP shall be required to reduce and maintain their groundwater withdrawals to comprise no more than 40% of the annual total water demand. Beginning with permits issued in 2035 and continuing thereafter, permittees operating under a certified GRP shall be required to reduce and maintain their groundwater withdrawals to comprise no more than 20% of the annual total water demand.
