Relating to the procedure for action on certain applications for an amendment to a water right.

HB 5518 modifies Texas water rights procedures by allowing the Texas Commission on Environmental Quality (TCEQ) to waive certain requirements for applications to amend water rights. It requires the TCEQ to find that a waiver would not harm the environment or the rights of other water permit holders before granting it. This bill directly affects individuals and entities seeking to modify existing water rights permits. The changes apply to applications filed on or after the bill's effective date or those pending as of that date. The law creates a formal process for waiving specific procedural requirements while maintaining environmental and rights protections.
