Federal transportation officials say the MBTA risks losing nearly $275 million in federal funds for "noncompliance" with hiring laws.

In a letter sent Monday, the Federal Transit and Highway administrations, ordered state Transportation Secretary Richard Davey and T chief Beverly Scott to submit a "remedial action plan" within 30 days to fix the T's workplace discrimination problems.

The Boston Herald, reports that the letter scolds the Massachusetts Bay Transportation Authority and the state Transportation Department for about 750 complaints over a three-year period. The T also paid more than $4 million in settlements, which it called "extremely troubling and disappointing."

The Transportation Department, the T's parent agency, released a statement saying it was working to address the issues and although progress is being made, more remains to be done.
