A deal between legislators to set up permanent mail-in voting rules would also convene a new MBTA board of directors to oversee the transit agency.

Legislators let the T’s dedicated governing body expire at the end of June without creating a replacement, after extending the board’s life by a year in mid-2020.

The permanent new panel would feature seven members who each serve four-year terms. The secretary of transportation would serve in an ex officio role, and one member would be selected by the MBTA Advisory Board, an independent group that represents the interests of the 176 cities and towns that help fund the T.

All five of the remaining members would be appointed by the governor, one of whom would need to be selected from a Massachusetts AFL-CIO shortlist.

MBTA board members would not be compensated for the position, but they could seek reimbursement for up to $6,000 in travel and other related expenses each year. That final provision reflects the House’s original bill, scrapping a Senate push to pay each board member a $12,000 stipend.

The T’s board would need to meet at least once a month and at least 12 times per year, another section in which the House’s proposal prevailed over the Senate’s suggestion to require at least 20 meetings per year. While the FMCB was widely praised for righting the transit agency’s ship in the years after the disastrous winter of 2015-2016, it was criticized for meeting too frequently. Preparing for the 36 hours-long meetings each year often distracted senior staff from important tasks, critics said.

When the FMCB expired, oversight of the MBTA reverted to the broader Department of Transportation Board of Directors that also focuses on highway, aeronautics and other rail infrastructure. That board has not met since June and is scheduled to convene next on July 26.
