5.  Plants in Column 1 are subject to normal NRC inspection activities.  Plants in Column 2, Column 3, or Column 4 are subject to progressively increasing levels of inspection by the NRC with, in general, progressively increasing levels of associated costs.  Continued plant operation is not permitted for plants in Column 5.  All of the nuclear generating plants owned and operated by Entergy’s Utility business are currently in Column 1.

Environmental Regulation

Entergy’s facilities and operations are subject to regulation by various governmental authorities having jurisdiction over air quality, water quality, control of toxic substances and hazardous and solid wastes, and other environmental matters.  Management believes that Entergy’s businesses are in substantial compliance with environmental regulations currently applicable to its facilities and operations, with reference to possible exceptions noted below.  Because environmental regulations are subject to change, future compliance requirements and costs cannot be precisely estimated.  Except to the extent discussed below, at this time compliance with federal, state, and local provisions regulating the discharge of materials into the environment, or otherwise protecting the environment, is incorporated into the routine cost structure of Entergy’s businesses and is not expected to have a material effect on their competitive position, results of operations, cash flows, or financial position.

Clean Air Act and Subsequent Amendments

The Clean Air Act and its amendments establish several programs that currently or in the future may affect Entergy’s fossil-fueled generation facilities and, to a lesser extent, certain operations at nuclear and other facilities.  Individual states also operate similar independent state programs or delegated federal programs that may include requirements more stringent than federal regulatory requirements.  These programs include:

•new source review and preconstruction permits for new sources of criteria air pollutants, greenhouse gases, and significant modifications to existing facilities;

•acid rain program for control of sulfur dioxide (SO2) and nitrogen oxides (NOx);

•nonattainment area programs for control of criteria air pollutants, which could include fee assessments for air pollutant emission sources under Section 185 of the Clean Air Act if attainment is not reached in a timely manner;

•hazardous air pollutant emissions reduction programs;

•interstate air transport;

•operating permit programs and enforcement of these and other Clean Air Act programs;

•regional haze programs; and

•new and existing source standards for greenhouse gas and other air emissions.

National Ambient Air Quality Standards

The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS)
