Worker Protection Standard Application Exclusion Zone
On October 30, 2020, EPA finalized updates to the AEZ provisions under the WPS. The 2020 Rule, originally set to go into effect on December 29, 2020, made modifications to the 2015 WPS/AEZ requirements.
In December 2020, two petitions were filed in the U.S. District Court for the Southern District of New York and in the U.S. Second Circuit Court of Appeals challenging the 2020 Rule (now consolidated as case number 20 Civ. 10642).
At this time, there is no implementation of the 2020 Rule as a preliminary injunction has stayed the effective date of the 2020 Rule and enjoined EPA from implementing the 2020 revisions. Therefore, until further notice, the 2015 WPS remains in effect with no changes to the AEZ provisions. This preliminary injunction is in effect until October 18, 2021, but could be extended as the litigation is ongoing. The 2020 Rule is concurrently undergoing review per the Executive Order on Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis.
View the AEZ comparison table. This table summarizes the differences between the 2015 WPS/AEZ requirements and the final rule EPA issued in the Federal Register on October 30, 2020.
