2023 Triennial Audit - Next Steps

The Department of Public Utilities (“DPU”), as the State Safety Oversight Agency for rail transit (subway lines) in Massachusetts, has completed a Triennial Audit of the Massachusetts Bay Transportation Authority’s (“MBTA”) Public Transportation Agency Safety Plan and its implementation. The Triennial Audit is a requirement of 49 C.F.R. § 674.31 and 220 CMR 151.10(2).

Upon issuance of this final report, MBTA must develop and submit CAPs for the Findings. Per 220 CMR 151.07 (3): “The Transportation Authority shall submit the CAP[s] to the Department for review and formal approval within 60 days of the identification of the Hazard and/or Risk or the event triggering the necessity of a CAP.” The Triennial Audit Report issue date is the start of such 60-day period.

The MBTA may submit a prioritization plan for CAP development, for DPU review and approval, to ensure that the highest priority CAPs are proposed and reviewed first.

For the Recommendations, MBTA must submit either written responses or CAPs. Please submit a schedule within 30 calendar days of the date of this report that proposes the timing and sequence of MBTA’s responses and/or CAPs on the Recommendations.
