(40 CFR Part 60, Subpart OOO)
EPA is submitting a pre-publication copy of the final MSW Landfills Federal Plan to implement the Emission Guidelines (EG) and Compliance Times issued on May 10, 2021. The Final Plan becomes effective 30 days after publication in the Federal Register, impacting any remaining landfills without approved EG Cf rules.
EPA’s federal plan includes an inventory of designated facilities and an estimate of emissions from those designated facilities. The Agency estimates 1,590 landfills will potentially be covered in 42 states and the US territories of Puerto Rico and the Virgin Islands, and one tribal entity.
SCS Engineers is preparing a Technical Bulletin for distribution to our mailing list and on social media. The Bulletin will consolidate 133 pages into several pages highlighting significant dates and impacts for you.
Affected are MSW landfills that commenced construction on or before July 17, 2014, and have not been modified or reconstructed since July 17, 2014.
EPA is implementing emission guideline requirements for existing MSW landfills located in states and Indian country where state plans or tribal plans are not currently in effect because they were not submitted or approved.
The Final 2016 Emission Guidelines for MSW Landfills require existing landfills that reach a landfill gas emissions threshold of 34 metric tons of nonmethane organic compounds (NMOC) or more per year to install a system to collect and control landfill gas (GCCS).
It also implements the emission limits, compliance schedules, testing, monitoring, reporting and recordkeeping requirements established in the Emission Guidelines for MSW Landfills.
Unless the landfill is a legacy controlled landfill, owners or operators of MSW landfills subject to the MSW Landfills Federal Plan must submit a design capacity report within 90 days after the effective date of the Federal plan (40 CFR 62.16724(a)).
Should the design capacity report indicate a capacity equal to or greater than 2.5 million Mg and 2.5 million m3 of solid waste a landfill can accept; then, an annual NMOC emission rate report must also be submitted within 90 days after the effective date of the Federal plan, and then every 12 months until the landfill installs a GCCS (40 CFR 62.16724(c)).
