What does Texas SB1583 do?
SB1583 mandates that Groundwater Conservation Districts (GCDs) amend their Management Plans within two years of adopting Desired Future Conditions (DFCs), regardless of pending litigation. This legislation eliminates the procedural loophole that previously allowed permit holders to stall the implementation of new groundwater restrictions by challenging the underlying scientific modeling. Implementation Timeline Effective Date: September 1, 2025 Compliance Deadline: Rolling deadline.
