RRC Publishes FAQ on Critical Designation of Natural Gas Infrastructure Forms

January 11, 2022

The Railroad Commission of Texas (RRC) has published Frequently Asked Questions related to filing Critical Designation of Natural Gas Infrastructure forms. To view the FAQ visit the RRC website at

The FAQ provide guidance on completion and submission of two newly adopted forms related to 16 TAC §3.65, which are required to be filed no later than January 15, 2022.

  • Form CI-D, Acknowledgement of Critical Customer/Critical Gas Supplier Designation, and its attachment would be submitted by an operator of a facility designated as critical acknowledging the facility’s critical status.
  • Form CI-X, Critical Designation Exception Application, and its attachment would be submitted by an operator certifying a facility seeks an exception to critical designation because the facility is not prepared to operate in a weather emergency.

The FAQ list is in addition to training videos and webinars, rules, and other resources also available on the RRC’s Critical Infrastructure Division page at

Critical Infrastructure Overview

Printable Overview

What we do

RRC’s Critical Infrastructure Division (CID) is committed to serving the people of Texas by ensuring the natural gas industry consistently incorporates weatherization and reliability standards and practices to achieve uninterruptible natural gas production throughout the calendar year including periods of severe weather.

The CID will vigilantly oversee and manage adherence to weatherization rules, adopted by the RRC, including ensuring companies within the natural gas supply chain register their assets as Critical Infrastructure.

On November 30, 2021 The Railroad Commission of Texas commissioners adopted rules for critical designation of natural gas infrastructure to help protect Texans in energy emergencies. The new rules implement provisions in House Bill 3648 and Senate Bill 3 and define natural gas facilities that would be designated as critical gas suppliers and critical customers.

Critical gas suppliers include, but are not limited to, gas wells, oil leases that produce gas, natural gas pipeline facilities, underground natural gas storage facilities and saltwater disposal facilities.

Critical customers, which are a subset of critical gas suppliers, are facilities that require electricity to operate. These operators will submit a critical customer information to their electric utilities so that their electric utilities have the correct information for purposes of supplying power to the facilities.

Senate Bill 3 includes language to allow for certain facilities to apply for an exception to critical designation. However, the newly adopted rules exclude certain types of highly critical facilities from being able to apply for an exception. Examples include any facility that will be on the state’s electricity supply chain map, which is due to be published next year, underground gas storage facilities, pipelines that directly serve a power generation plant or local gas distribution companies, gas wells and oil leases that produce a large amount of gas per day, and gas processing plants. Applications for exception require objective evidence proving reasonable cause and justification, which will be reviewed, and RRC staff can deny an application.
