After a State becomes certified to regulate its intrastate facilities, the Secretary may monitor a safety program to ensure that the program complies with the certification. If PHMSA determines that the State is not satisfactorily enforcing compliance with applicable prescribed safety standards, PHMSA may reject the certification, assert U.S. Government jurisdiction, or take other appropriate action to achieve adequate enforcement. This rulemaking proposes to codify the administrative process and procedures PHMSA proposes to follow if a State is found to have such deficiencies in its pipeline safety program that it is not satisfactorily complying with the certification requirements and the statute. The proposed process and procedures would include a finding of unsatisfactory compliance elements, considerations and alternatives before PHMSA rejects a State's certification or takes other appropriate action to ensure compliance, providing a State with notice and an opportunity for a hearing before PHMSA takes final action, and reinstatement of State certification.
