The Public Transportation Agency Safety Plan regulation at 49 C.F.R. Part 673 (Part 673) requires each rail transit agency (RTA) to develop an Agency Safety Plan (ASP) and certify that it meets Part 673 requirements by no later than July 20, 2020. In addition, as specified in § 673.13, and authorized in FTA’s State Safety Oversight regulation, 49 C.F.R. Part 674, the State Safety Oversight Agency (SSOA) must review and approve the RTA’s ASP, prior to the RTA’s certification of compliance to FTA. To approve the ASP, the SSOA must confirm that the RTA’s ASP meets both FTA’s Part 673 requirements and the SSOA’s Program Standard.
