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 to help municipalities upgrade improperly closed sanitary landfills (those shut down before June 1, 1987, without proper closure). It directly affects municipalities owning such landfills by providing financial assistance for specific safety upgrades, including covers, methane monitoring systems, and leachate collection. The program requires municipalities to apply with project details, prioritizes projects with the greatest environmental and health impact, and mandates annual reports on fund usage. Grants cover only costs not offset by federal funding, aiming to meet state closure standards and reduce pollution risks from these aging sites.
