Pipeline and Hazardous Materials Safety Administration November 17, 2017 – Federal Register Recent Federal Regulation Documents

To standardize manufacturer and reconditioner approvals, PHMSA is proposing to terminate any M-number and R-number approvals that were previously issued without an expiration date. The termination of these approvals will take effect one year from the publication date of this notice. Approval holders must either show cause why their approvals should not be terminated or apply for a modification of their approval prior to the effective date to avoid termination. Once terminated, requests for reconsideration of the termination must be submitted within 20 days of the date of termination.
