HB 5123 revises financial assurance requirements for oil and gas operators under the jurisdiction of the Railroad Commission of Texas. It allows operators to meet financial security obligations for produced water recycling pits and related facilities through mechanisms such as self-insurance and parental bonding. Operators with multiple subsidiaries may satisfy bonding requirements through a single consolidated bond, subject to financial adequacy verification. The Railroad Commission must implement rules to ensure proper financial responsibility is maintained when assets are transferred​.
