Comprehensive Environmental Response, Compensation, and Liability Act of 1980

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (CERCLA), authorizes the EPA to mandate clean-up by, or to collect reimbursement of clean-up costs from, owners or operators of sites at which hazardous substances may be or have been released.  Certain private parties also may use CERCLA to recover response costs.  Parties that transported hazardous substances to these sites or arranged for the disposal of the substances are also deemed liable by CERCLA.  CERCLA has been interpreted to impose strict, joint, and several liability on responsible parties.  Many states have adopted programs similar to CERCLA.  Entergy subsidiaries have sent waste materials to various disposal sites over the years, and releases have occurred at Entergy facilities including nuclear facilities that have been sold to decommissioning companies.  In addition, environmental laws now regulate certain of Entergy’s operating procedures and maintenance practices that historically were not subject to regulation.  Some disposal sites used by Entergy subsidiaries have been the subject of governmental action under CERCLA or similar state programs, resulting in site clean-up activities.  Entergy subsidiaries have participated to various degrees in accordance with their respective potential liabilities in such site clean-ups and have developed experience with clean-up costs.  The affected Entergy subsidiaries have established provisions for the liabilities for such environmental clean-up and restoration activities.  Details of potentially material CERCLA and similar state program liabilities are discussed in the “Other Environmental Matters” section below.

Coal Combustion Residuals

In April 2015 the EPA published the final coal combustion residuals (CCR) rule (2015 CCR Rule) regulating CCRs destined for disposal in landfills or surface impoundments as non-hazardous wastes regulated under Resource Conservation and Recovery Act Subtitle D.  The final regulations created new compliance requirements including modified storage, new notification and reporting practices, product disposal considerations, and CCR unit closure criteria but excluded CCRs that are beneficially reused in certain processes.  Entergy believes that on-site disposal options will be available at its facilities, to the extent needed.

Pursuant to the 2015 CCR Rule, Entergy operates groundwater monitoring systems
