Section 2QQQQ. There shall be established and set up on the books of the commonwealth a separate fund to be known as the Logan Airport Health Study Trust Fund to be expended, without prior appropriation, by the department of public health. The fund shall consist of monies allocated by the Massachusetts Port Authority or any other public or private entity to the department of public health to conduct public health activities associated with the Logan Airport Health Study, conducted pursuant to item 4510–0600 of chapter 159 of the acts of 2000. The commissioner of public health shall make necessary expenditures from the fund for administration and project management activities and for direct support to community health centers within the study area. The department may incur expenses and the comptroller may certify for payment amounts in anticipation of expected receipts, but no expenditure shall be made from the fund that would cause the fund to be in deficit at the close of a fiscal year. Monies deposited in the fund that are unexpended at the end of the fiscal year shall not revert to the General Fund.
