PHMSA's Webinar for M/R-Number Approval Termination

This webinar provides you with a basic understanding of Manufacturer and Reconditioner Approval numbers, and why PHMSA is proposing termination of current M-number approvals (without an expiration) and all R-number approvals. Federal Register Notice Docket No. PHMSA-2017-0084 Notice No. 2017-03 was published on November 17, 2017 and describes the proposal to terminate M- and R- numbers. Unexpired M-number approval holders MUST contact approvals@dot.gov prior to November 17, 2018 to modify their approval with a new 5-year expiration date. Current R-number approval holders who wish to maintain their approval must request a new M-number from PHMSA—linked to their R-number—that will include a 5-year expiration date.
