Kilgore Office Closed

Due to a power outage, the RRC’s Kilgore office will be closed Friday, September 13.  We will resume normal hours on Monday, September 16. We apologize for any inconvenience.


The Regulations for Compressed Natural Gas require each individual performing regulated activities to be certified through examination. There are two different levels of examination: Management and Employee.

A licensee must employ at least one company representative who has passed the applicable management-level qualifying examination and met all applicable training requirements. Each license category has a corresponding management level exam. A company representative applicant may not perform work or be employed in any capacity requiring contact with CNG before these requirements are met. Management-level examinations are closed book.

No individual may perform work or be employed in any capacity requiring contact with CNG until he or she has passed the required Railroad Commission qualifying examination. Employee-level examinations are open book. The Commission will provide the publications to be used during the exam
