EPA Proposes to Delay Compliance Timeframe for GHG Guidelines at Municipal Solid Waste Landfills The Environmental Protection Agency (EPA) published a proposed rule to amend the greenhouse gas emission guidelines for municipal solid waste (MSW) landfills. The proposal would postpone the due date for state plans promulgated pursuant to these guidelines from May 30, 2017 to August 29, 2019. The EPA is also taking comment on whether it should amend the guidelines to require states to resubmit their plans in accordance with new guidelines. EPA is accepting comment on this proposal through December 14, 2018. Interested parties can comment here.
