RCRA Corrective Action, Closure, and Stewardship

The Department of Energy and Environmental Protection (DEEP) says Connecticut is authorized for Resource Conservation and Recovery Act (RCRA) Closure and Corrective Action. DEEP's page, last modified July 10, 2026, says RCRA requires facility owners and operators to clean up properties that have treated, stored or disposed of hazardous waste at their facility, and that this is implemented through a permit, order or, for land disposal facilities, regulation.

In a Phase I ESA

This is the Connecticut record of corrective action and closure at hazardous waste facilities. It sits beside the federal corrective action records described on the RCRA CORRACTS page. ASTM E1527-21 lists state hazardous waste facility records among its standard sources. This handbook does not pair a single Connecticut list with that type, because DEEP's page publishes no list of corrective action facilities. This is one of the Connecticut records that bear on it.

• Corrective action can sit in a permit. DEEP says RCRA facilities must investigate all areas of concern sitewide, and that investigation and remediation not completed by the time a permit is issued will be included in the permit.
• A stewardship permit records long-term duties. DEEP describes a Stewardship Permit as one that defines long-term obligations for the permit holder, is transferable to future owners, provides public participation during the cleanup, documents cleanup as it is completed and imposes financial assurance, possibly in phases. It links a presentation that explains the use of Stewardship Permits, which it writes as "RCRA Part B Post-Closure Permits", to implement RCRA Corrective Action. DEEP links a page of examples of stewardship permits issued, which was not read for this page.
• Closure is a separate duty. DEEP says RCRA requires operators to remove hazardous waste from treatment and storage areas and to either remove waste from land disposal units or close them as a land disposal facility. It says once wastes are removed, facilities and generators must decontaminate the area and equipment, and any releases to the environment must be remediated. DEEP links closure guidance for container storage areas and tank systems and for indoor storage areas.
• Ecological risk is part of the work. DEEP says ecological risk evaluation is required for all RCRA Corrective Action sites.

DEEP says such clean-up work may be coordinated with work under other clean-up authorities in Connecticut. DEEP's list of Contaminated or Potentially Contaminated Sites says RCRA Corrective Action sites are among its sources.

Where to look a site up

• The page names no lookup tool for corrective action facilities. DEEP's list of contaminated or potentially contaminated sites is the nearest list it names, and its Release, Environmental Assessment, and Cleanup Tracker is where it says to search for properties where releases have occurred.
• For stewardship permits, DEEP gives DEEP.REMStewardship@ct.gov at its Remediation Division, Water Protection and Land Reuse Bureau.
• DEEP's Hazardous Waste page, last modified February 27, 2025, links a Hazardous Waste Treatment, Storage and Disposal Facilities page and a Property Transfer Program page for cleanup of hazardous waste sites. That page is older than the sunset described on the Property Transfer Program page. See the Hazardous Waste page.

Getting the file

DEEP's Records Center page, content last updated July 2024, lists RCRA Facilities permits dated from 1985 and groundwater monitoring dated from 1981 among the files of the Bureau of Materials Management and Compliance Assurance. See the Environmental Quality Records Center page for appointments.
