AB-709: Updating Groundwater Plan Rules

This law clarifies that agencies managing groundwater can change their coordination agreements after the state reviews and assesses their plans.

What This Bill Does

  • Requires local agencies to submit groundwater sustainability plans to the Department of Water Resources for review upon adoption.
  • Mandates a joint submission when multiple agencies cover an entire basin with separate plans, including the plans, an explanation of how they meet act provisions, and their coordination agreement.
  • Sets a rule that the department must evaluate each plan within two years of receiving it and issue an assessment.
  • Allows agencies to amend their coordination agreements after the state issues its assessment.

Who It Names or Affects

  • Groundwater sustainability agencies managing high- or medium-priority basins.
  • The Department of Water Resources, which reviews and assesses the plans.

Limits and Unknowns
