This Frequently Asked Questions (FAQs) guidance document provides additional information on operator qualification regulations.  PHMSA provides FAQs to help the public understand how to comply with the existing requirements under the Regulations, but FAQs are not substantive rules, are not meant to bind the public in any way, and do not assign duties, create legally enforceable rights, or impose new obligations that are not otherwise contained in the existing regulations and standards. PHMSA issued a final rule governing OQ programs that can be found at 64 FN 46853 (Aug. 27, 1999).
