Relating to the consideration by a groundwater conservation district of modeled available groundwater when issuing permits.

HB 24 limits groundwater conservation districts in Texas from issuing permits that would allow an applicant to withdraw and transfer out more than 5% of the district's estimated sustainable groundwater supply. It directly affects groundwater conservation districts and applicants seeking new permits for groundwater production and transfer. The bill requires districts to calculate this 5% cap based on "modeled available groundwater" determined by the district's executive administrator. This rule applies only to permits issued on or after the bill's effective date, which is 91 days after the legislative session ends.
