Alternative Fuels ANNOUNCEMENTS

NOTICE TO ALL RRC REGULATED OPERATORS

Increased Possibility of Cyber Attacks
April 10, 2026

The Environmental Protection Agency (EPA) and the Cybersecurity and Infrastructure Security Agency (CISA) issued new advisories this week warning of an increased possibility of cyber attacks.

These attacks are targeting internet-facing operational technology (OT) devices, including programmable logic controllers (PLCs) across US critical infrastructure potentially causing operational disruption and financial loss.

Some organizations in critical infrastructure sectors have already experienced disruptions caused by malicious interactions with the project files and the manipulation of data displayed on human machine interface (HMI) and supervisory control and data acquisition (SCADA) displays.

Recommended Actions from CISA

Operators should take the following steps to strengthen cyber resilience:

  • Remove PLCs from direct internet exposure via secure gateway and firewall.
  • Query available logs for the provided IOCs in the corresponding time frames.
  • Check available logs for suspicious traffic on the ports associated with OT devices, including 44818, 2222, 102, and 502, especially traffic originating from overseas hosting providers.
  • For Rockwell Automation devices
    • Place the physical mode switch on the controller into run position.
    • Contact the authoring agencies and Rockwell Automation for guidance if you believe your organization was targeted.

Additional Resources:

The RRC maintains a 24-hour, toll-free emergency line, 844-773-0305, to report emergencies, including leaks or spills and damage to gas pipelines.

What we do

The Oversight and Safety Division has responsibility for Alternative Fuels, Gas Services and Pipeline Safety. This reorganization in January 2015 will bring even greater efficiency and consistency to these operations within the Commission, allowing the agency to better serve the state.

The Railroad Commission of Texas (Commission) is the state agency responsible for regulating the safe storage, transportation and use of Liquefied Petroleum Gas (LPG, Propane, Butane), Compressed Natural Gas (CNG), and Liquefied Natural Gas (LNG), pursuant to the Texas Natural Resources Code (TNRC). The Commission has also adopted regulations for each fuel type under the Texas Administrative Code, Title 16, Chapters 9, 13, and 14, respectively.

The Alternative Fuels Safety (AFS) department enforces both the state statutes and the Commission’s regulations on these fuels, by conducting safety evaluations of stationary facilities and mobile equipment, licensing companies engaged in alternative fuel activities, and providing training to individuals working in the alternative fuels industries.
