Establishes grant program in DEP to provide financial assistance to municipalities for infrastructure and other physical upgrades to certain municipally owned sanitary landfill facilities closed before June 1987; appropriates $10 million.

This bill establishes a $10 million grant program within New Jersey's Department of Environmental Protection (DEP) to help municipalities upgrade improperly closed sanitary landfills. It specifically targets municipally owned landfills closed before June 1987 without completing required closure activities (like installing covers, gas vents, or monitoring systems), which pose pollution and health risks. Municipalities can apply for grants covering infrastructure costs to meet DEP standards for proper closure, capping, and post-closure care, with priority given to projects that most effectively prevent environmental hazards. The program requires annual reports from recipients on fund usage and DEP to submit annual effectiveness reports to the Governor and Legislature.
