EPA is promulgating a Federal plan to implement the Emission Guidelines (EG) and Compliance Times for Municipal Solid Waste (MSW) Landfills (2016 MSW Landfills EG) for existing MSW landfills located in states and Indian country where state plans or tribal plans are not in effect. This MSW Landfills Federal Plan includes the same elements as required for a state plan: Identification of legal authority and mechanisms for implementation; inventory of designated facilities; emissions inventory; emission limits; compliance schedules; a process for the EPA or state review of design plans for site-specific gas collection and control systems (GCCS); testing, monitoring, reporting and record keeping requirements; and public hearing requirements. Additionally, this action summarizes implementation and delegation of authority of the MSW Landfills Federal Plan. The final rule is effective on 21 June 2021.
