Should the federal government keep its old public records and websites online?
The Environmental Protection Agency plans to decommission its online web archive by December 31, 2026. The archive holds tens of thousands of documents covering at least 20 years of agency history.
Why it matters
The archive is a record of federal environmental documentation, and its closure would affect public access to that history. The EPA has proposed snapshot collections as an alternative to the full archive.
The 2022 closure plan cited approximately $2 million in annual maintenance costs for the archive, which covers at least 20 years of EPA history. The stub does not indicate how much of the archive the proposed snapshot collections would retain.
The players
Environmental Protection Agency
The federal agency responsible for environmental protection in the United States, which maintains the web archive and announced its planned decommissioning.
The details
The EPA first announced plans to close the archive in January 2022 and delayed the shutdown to July 2023. In March 2023 it removed the end date from the retirement notice, and the archive was not updated during the following three-and-a-half years, which the archive's broken links and search constraints reflect. The agency posted a notice on its website disclosing the decommissioning plan and declined to provide comment.
Timeline
January 2022: EPA first announced plans to close the archive.
July 2023: EPA delayed the shutdown to this date.
March 2023: EPA removed the end date from the archive's retirement notice.
December 31, 2026: Scheduled decommissioning deadline for the archive.
Roadmap
The planned closure follows a pattern in which the EPA's own deadline moved from 2022 to 2023 before being set for December 2026. The archive's retirement notice, which had dropped its end date in 2023, now carries a firm date that sets it apart from that earlier uncertainty.
Researchers, journalists and members of the public who rely on the archive for historical EPA documents would lose access to it once it is decommissioned. The snapshot collections the agency has proposed would be the remaining route to that material, and the stub does not say how complete they would be.
The takeaway
Anyone who needs EPA documents from the archive should identify and save the material before the December 31, 2026 deadline, since the broken links and search limits already make it harder to use. The agency's own history shows the deadline has moved before, so it is worth tracking any official changes.
What happens next
The archive is scheduled to be decommissioned on December 31, 2026, and the EPA has proposed snapshot collections as an alternative.
