The MBTA will see its federal security funding cut in half, according to a Boston Globe report.

Recent years have seen a steady decline for transit agency grants as well as a nationwide drop in grants to local and state transportation authorities overall. MBTA officials said the agency will receive just $3.25 million in grant funding, down from the $6.6 million they received in 2012. The transportation agency had applied for $15 million in security grants for 2013.

The reduction in funding means that a range of projects, such as additional security measures at stations, yards, and tunnels will be scrapped. Police staffing levels or some “other planned security improvements” will not be affected.

According to an MBTA official, reduced grant funding would not affect core operations.

The Homeland Security Department provided the MBTA $29 million in grants in 2009. Funding has since dropped.

Nationally, the department cut grants by $74 million, but still allocated $1.5 billion to states and urban areas.

Federal funding awarded several years ago allowed the MBTA to establish a $10 million emergency training center, built in an abandoned South Boston tunnel, that opened this past June.

Bill Keating revealed last month that the Boston area had received $17.5 million in total homeland security grants, up nearly $7 million from the previous year.

Keating, a member of the House Committee on Homeland Security, believes that the city’s response to the Boston Marathon bombings demonstrated the importance of security spending.
