EPA Deletes Eight Fully Remediated Hazardous Waste Sites from Superfund Priority List

WASHINGTON, DC — The Environmental Protection Agency published a final administrative rule in the Federal Register Thursday afternoon, officially deleting eight contaminated industrial properties from the National Priorities List (NPL) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA/Superfund).

CERCLA Remediation Standards and Deletion Criteria

The rule executes the full deletion of six hazardous waste sites located in Indiana, Ohio, Pennsylvania, North Carolina, Missouri, and Washington state, along with the partial deletion of two industrial parcels in New Jersey and Texas. The EPA confirmed that multi-year engineering remedies—including in-situ groundwater bioremediation, heavy metal soil stabilization, and impermeable capping—have successfully reduced toxic contamination below statutory health thresholds, making the land safe for unrestricted commercial and recreational reuse.

The agency worked in direct partnership with state environmental protection departments and local health agencies to complete comprehensive five-year monitoring reviews.

Economic Redevelopment and Brownfield Opportunities

Local municipal mayors and regional economic development corporations praised the formal deletions, noting that removing the Superfund designation removes legal stigma and enables private commercial developers to finance light industrial parks, solar arrays, and public parkland on former brownfields.

Community advisory boards noted that ongoing post-closure groundwater monitoring will remain in place to ensure long-term containment integrity.

Public Register Effective Date

The administrative deletions take effect immediately upon publication in the Federal Register.
