The National Priorities List (NPL) is updated periodically, as mandated by CERCLA (CERCLA Overview). The EPA publishes the list of NPL sites in the Federal Register.

The EPA published rules in the Federal Register on September 3, 2020, proposing to add four sites and adding six sites to the NPL. The EPA also withdrew its previous proposal to add the Capitol City Plume site in Montgomery, AL to the NPL. Additional information about this site can be found in the De-Proposal Memo (130 pp, 14.0 MB, About PDF).

• Federal Register Notice of the Current NPL Proposed Rule (PDF),(7 pp, 313 K, About PDF).
• Federal Register Notice of the Current NPL Final Rule (PDF), (6 pp, 293 K, About PDF).

The Superfund program publishes documents with each rulemaking adding or proposing sites to the National Priorities List (NPL). Notification and listing of the sites are published in the Federal Register.

Depending on the action being taken by EPA, the Federal Register notice describes either the addition of sites to the NPL (final rule) or the proposal to add sites to the NPL (proposed rule). Notices for both actions provide a list of sites; background information about the NPL process, including information about the Superfund rules; and other site actions. The proposed rule notice also provides information about submitting comments on the sites proposed.
