The National Priorities List is updated periodically, as mandated by CERCLA (CERCLA Overview). EPA publishes the list of NPL sites in the Federal Register. The EPA published a rule in the Federal Register on September 30, 2015, proposing to add seven sites and adding five sites to the NPL.

• Federal Register Notice of the Current Final National Priorities List (NPL) Rule, published September 30, 2015 (PDF) (6 pp, 240 K)
• Federal Register Notice of the Current Proposed National Priorities List (NPL) Rule, published September 30, 2015 (PDF) (6 pp, 217 K)

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.

New Proposed NPL Sites

EPA published a rule proposing to add seven sites to the NPL in the September 30, 2015, Federal Register. A total of 53 sites are proposed (Proposed National Priorities List (NPL) Sites) to the NPL as of this rulemaking. General information about site location, operations, contaminants, and site investigation activities is provided by the NPL Site Narrative at Listing. The HRS Documentation Record provides in-depth information about each site that is scored using the HRS (Introduction to the HRS). The document provides the basis for EPA's decision to propose sites to the NPL. A letter from the State is provided in lieu of the HRS Documentation Record when a site is proposed to the NPL as a State or Territory top-priority site regardless of HRS score. A letter from the State and other supporting documentation is provided in lieu of the HRS Documentation Record when a site is proposed to the NPL as an ATSDR site without the need to apply the HRS.

DISCLAIMER: The documentation records and narrative summaries provided on this page are the documentation records and narrative summaries available at the time of proposal. These documents are provided for informational purposes. The official copies of the documentation records, narrative summaries, and State concurrence letters are available at the EPA Headquarters Superfund Docket.
