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 creates a $10 million grant program within New Jersey's Department of Environmental Protection (DEP) to help municipalities fix outdated sanitary landfills that closed improperly before June 1, 1987. Municipalities owning such landfills can apply for grants to cover costs for infrastructure upgrades like methane gas vents, leachate monitoring systems, and proper capping to meet DEP closure standards. Applicants must prove their landfill was improperly closed and detail how upgrades will reduce pollution and health risks, with grants only covering costs not already funded by federal sources. The DEP must prioritize projects with the greatest environmental benefits, and applications require specific project plans and cost breakdowns.
