Requires owners and operators of certain landfills to control and monitor landfill gas emissions.

This bill requires owners and operators of certain New Jersey sanitary landfills (those accepting waste or closing after the effective date) to control methane emissions. It mandates installing gas collection systems, conducting quarterly methane monitoring, and ensuring emissions stay below 500 ppm at any single point or 25 ppm averaged across the site. Landfill operators must submit annual methane estimates, maintain records, and meet specific technical standards for gas systems, including 99% methane destruction efficiency. These requirements apply to new systems or modifications after the bill takes effect.
