and/or the public at risk or cause damage to the surrounding environment. Examples of AES Regulated Materials include, but are not limited to, oil/petroleum

products, hazardous and extremely hazardous substances. Potable water, fire water, some process waters (i.e., demineralized water) and waste materials a

considered an AES Regulated Material.

Environmental Control Equipment - Installed equipment or systems designed to reduce or render less harmful uncontrolled pollutant loads and/or concentrati

AES air emission, wastewater discharge, waste generation, and other environmental media streams.

Environmental Monitoring Equipment - Installed equipment or systems designed to quantify or otherwise measure pollutant loads and/or concentrations from

emission, wastewater discharge, waste generation, and other environmental media streams.

Hazardous Waste - These are wastes that have unique characteristics such as being explosive, flammable, oxidizing, poisonous, infectious, corrosive, toxic a

ecotoxic which, if not properly managed and disposed, would result in significant harm to the public and/or the environment. A waste is deemed to be haza

under this standard if (1) it is so classified by local applicable rules and regulations, or (2) it qualifies as being hazardous under the "Basel Convention on the

of Transboundary Movements of Hazardous Wastes and their Disposal" sponsored by the United Nations Environment Program and adopted on 22 March 19

Other Waste - Non-Hazardous or Special Waste solid waste streams such as municipal solid waste/rubbish, scrap metals, and construction debris.

PCB - Polychlorinated Biphenyls in concentrations higher than 500 ppm. This includes liquids, equipment and wastes generated as a result of cleanup of PCB

PCB Contaminated - Polychlorinated Biphenyls in concentrations between 50 ppm and 500 ppm. This includes liquids, equipment and waste generated as a

cleanup of PCB contaminated material.

AES Reportable Spills - Any liquid spill of AES Regulated Material, Hazardous Waste, Special Waste or PCBs that is reportable to local environmental regulato

that is lost off AES Location property into the environment at a quantity equaling or exceeding 55 gallons (210 liters). Spills causing significant environmenta

or public media interest should be reported immediately to AES Corporate Environmental Affairs, and all other spills can be reported on a monthly basis but

then the 10th calendar day of the month after they occur using the AESOnline environmental nonconformance event module.

Special Waste - For the purposes of this standard, special wastes only include used oil, asbestos, mercury containing light bulbs/switches and batteries.

Spill - A release of any quantity of liquid AES Regulated Material, Hazardous Waste or Special Waste outside of an aboveground bulk storage tank, undergrou

storage tank, equipment reservoir, container, or process at the AES business.

businesses are:

1 & 2. PCB Management Program Requirements for AES Elecric Power Generation & Transmission (electrical equipment 69 kV or greater) Businesses



24/49


a. A PCB Management Program must be in place at an AES electric power generation plant or transmission business for the following situations: (a) for

managing oil-filled electrical equipment that has been identified as containing PCBs, and (b) for oil-filled electrical equipment of unknown PCB content that is

undergoing maintenance resulting in exposure to the oil, oil has spilled from the equipment, or the equipment is being disposed of offsite.

b. It must be assumed that oil releases and exposures from any electrical equipment with unknown PCB content undergoing maintenance, from a spill, or for

equipment being disposed of offsite is PCB Contaminated (contains PCBs between 50 and 500 ppm). The only way an AES business can treat the equipmenas being PCB Free (i.e., containing oil with a concentration less then 50 ppm) is via testing or irrefutable manufacturers information. It is deemed to be a

best practice to lower the threshold for designating oils to be PCB Free if tested or verified to be 2 ppm or below.

c. Any transformers installed back into the power plant or transmission network must be PCB Free (less then 50 ppm is mandatory, and 2 ppm or less is

deemed to be a best practice) and be inventoried as such.

d. Although it is a best practice, there is no mandatory AES requirement to test electrical equipment that is in-service at an electric power generation plant or

transmission business.

hire, annually thereafter or when waste management procedures change. The training program for PCBs management must as a minimum cover the

following topics: proper waste handling procedures; proper completion of transfer/inventory records; procedures to avoid incidents/injury; proper labeling,

storage and disposal procedures; and spill notification and response procedures.


Permanent Container Storage Area - These are areas at AES Locations with the capacity to store multiple Containers of PCB Items. They do not include single

Containers that are in active use in work areas (so-called satellite containers).

Properly Labeled - Permanent Container labeling that clearly identifies the waste material within the Container, and the date the last quantity of waste was

introduced into the Container and the Container sealed.

FAS 5 - Statement of Financial Accounting Standards No. 5, Accounting for Contingencies, provides the accounting standard for disclosure of material continge

liabilities that can be expressed on a company's balance sheet. It requires a company to accrue a charge against current income for the entire amount of a ma

liability that is "probable" and can be estimated reasonably. Contingent liabilities may be expressed as a range of estimable values. If the material contingent li

is "reasonably possible" but cannot be estimated, FAS 5 requires the liability to be disclosed in the footnotes of the company's financial statements. Environme

related contingencies at an AES Entity can include, but may not necessarily be limited to, pending environmental fines/penalties, contaminated land environme

remediation not related to future asset retirement, and additional costs due to new environmental applicable requirements (e.g., climate change legislation).

FAS 143 - Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations, requires a company to recognize on their balanc

sheets the fair value of a legal asset retirement obligation (ARO) in the period in which it is incurred, if a reasonable estimate of fair value can be made. A com

property, plant and equipment are all examples of long-lived assets which may be subject to retirement obligations, which includes abandonment, recycling an

disposal. Environmentally-related AROs at an AES Entity can include, but may not necessarily be limited to, asbestos removal, PCB remediation, site environm

remediation, and closing of environmentally hazardous operations, all to be performed at the time of equipment or site retirement.

conditional asset retirement obligations (CAROs) which are defined as a legal obligations to be performed during asset retirement activities where the timing or

Reporting into the AESOnline System - An AES Entity must report and keep continually updated into the AESOnline System all its environmentally-related FAS 5

contingencies (including the contingent environmental reserve amount) and FAS 143 asset retirement obligations as "Environmental Operating Events" (EOEs).

Environmentally-related FAS 5 contingencies must be categorized as a "Contingent environmental reserve created for business" EOE category and the requested
