30 Tex. Admin. Code § 312.146
In the event of a discharge or spill of waste during collection or transportation, the collector or transporter must take appropriate action to protect human health and the environment ( e.g., notify local law enforcement and health authorities; dike the discharge area; clean up any waste discharge that occurs during transportation; or take such action as may be required or approved by federal, state, or local officials having jurisdiction so that the waste discharge no longer presents a human health or environmental problem). Transporters are responsible for reporting certain spills to the executive director in accordance with requirements of the State of Texas Oil and Hazardous Substance Spill Contingency Plan and the Texas Water Code, Chapter 26.039.
