The EPA finalized the Standards of Performance for Municipal Solid Waste Landfills on August 29, 2016 (81 FR 59332) and its companion rule, Emission Guidelines and Compliance Times for Municipal Solid Waste Landfills, also finalized on August 29, 2016 (81 FR 59276). The EPA received a petition in response to the final rules from industry representatives. The petition raised at least one objection to the rule requirements included in the final rule that arose after the comment period or was impracticable to raise during the comment period and that is of central relevance to the rule. In a letter signed May 5, 2017, the Administrator granted reconsideration and showed intent to stay the rules in their entirety. In a previous action, both the new source performance standards and emission guidelines were stayed for 90 days. The EPA intends to further extend the stay in this action. Sources will not need to comply with any requirements under these rules while the stay is in effect.
