EPA Administrator Andrew Wheeler Updates Superfund Emphasis List

Contact Information: 
Elias Rodriguez (

NEW YORK – Today, the U.S. Environmental Protection Agency (EPA) announced a revision to the Administrator’s Emphasis List of Superfund Sites Targeted for Immediate, Intense Action (Administrator’s Emphasis List). The Diamond Alkali/Passaic site in Newark, New Jersey was removed from the list, and three sites were added: the Arsenic Mine site in Kent, New York; the San Mateo Creek Basin Legacy Uranium Mines site in Cibola and McKinley Counties, New Mexico; and the Petroleum Products site in Pembroke Park, Florida. With this update, there are a total of 17 Superfund sites on the list, and a total of 14 sites have been removed from the Administrator’s Emphasis List since December 2017 because the short-term milestones were achieved.

“With this update, EPA achieves an important milestone at the Diamond Alkali site and also adds three additional sites to the Administrator’s Emphasis List for immediate attention and action,” said EPA Administrator Andrew Wheeler. “These updates demonstrate our continued progress in the Superfund program and our commitment to accelerate the cleanup of the nation’s most contaminated sites. In Fiscal Year 2018, EPA deleted more sites off Superfund’s National Priorities List than any other single year since 2005, and we’re on pace to delete even more this year.”

“Placing Arsenic Mine on the Administrator’s Emphasis List underscores EPA’s commitment to investigate this site and find the appropriate avenue for addressing it. We are pursuing inclusion on the National Priorities List to provide a strong framework for protecting public health and the environment at the site,” said Regional Administrator Pete Lopez. “Removing the Diamond Alkali Site from the list after completing the important remedial investigation work is further evidence of the strides we are making to advance projects in the Superfund program.”

Removing the Diamond Alkali/Passaic Superfund site from the Administrator’s Emphasis List reflects another significant achievement under the Superfund Task Force. The site was placed on the list with the goal of finalizing the remedial investigation. EPA approved the remedial investigation on June 28, 2019, advancing the process forward toward developing a feasibility study to evaluate potential interim cleanup actions. These actions will address contamination that has impacted the quality of the Passaic River and the community’s ability to use the river.

On June 3, 2019, EPA proposed the Arsenic Mine site to the National Priorities List (NPL) after the Agency for Toxic Substances and Disease Registry issued a public health advisory. EPA will consider public comments on the proposal to list the site and make a final determination by the end of calendar year 2019.

At the San Mateo Creek Basin Legacy Uranium Mines site, EPA will obtain responsible party commitments to perform the equivalent of a remedial investigation/feasibility study assessment of the San Mateo Basin. Reaching this milestone will move the site closer to the selection of a cleanup remedy.

At the Petroleum Products site, EPA will propose a final remedy to address contaminated soil and its source and will propose an interim remedy for the contaminated groundwater at the site. 


EPA established the Administrator’s Emphasis List in December 2017 in response to recommendations from EPA’s Superfund Task Force. Each site on the Administrator’s Emphasis List has a short-term milestone to provide the basis for tracking the site’s progress. EPA will consider removing a site from the list once the milestone is achieved. Removal from the Administrator’s Emphasis List does not change the site’s status on the National Priorities List. 

EPA remains committed to addressing risks at all Superfund sites, not just those on the Administrator’s Emphasis List. The Superfund Task Force Recommendations are aimed at expediting cleanup at all Superfund sites. EPA continues to accelerate progress at Superfund sites across the country.
