The Department of Sanitation awarded Queens-based Tully Construction Co. Inc. a contract this month for the final cover and closure of a more than 460-acre section of Fresh Kills Landfill, which is being turned into a park, a spokeswoman for the agency said.

The parcel of land, dubbed section 1/9, already has nearly 30 percent of its closure work completed and the new contract targets the more than 320-acres still left, Sanitation said.

The project will place final cover over solid waste that's made up of a series of layers that help facilitate the movement of landfill gas to extraction wells, drain water, plant vegetation and more, according to the Parks Department.
