Annual Report (Form 10-K), fiscal year 1993

ITEM 1. BUSINESS
Southern California Edison Company ("Edison") was incorporated under California law in 1909. Edison is a public utility primarily engaged in the business of supplying electric energy to a 50,000 square-mile area of central and southern California, excluding the City of Los Angeles and certain other cities. This area includes some 800 cities and communities and a population of nearly 11 million people. As of December 31, 1993, Edison had 16,487 full-time employees. During 1993, 37% of Edison's total operating revenue was derived from commercial customers, 36% from residential customers, 13% from industrial customers, 8% from public authorities, 4% from agricultural and other customers and 2% from resale customers. Edison comprises the major portion of the assets and revenues of SCEcorp, its parent holding company.
REGULATION
Edison's retail operations are subject to regulation by the California Public Utilities Commission ("CPUC"). The CPUC has the authority to regulate, among other things, retail rates, issuances of securities and accounting and depreciation practices. Edison's resale operations are subject to regulation by the Federal Energy Regulatory Commission ("FERC"). The FERC has the authority to regulate resale rates as well as other matters, including transmission service pricing, accounting and depreciation practices and licensing of hydroelectric projects.
Edison is subject to the jurisdiction of the Nuclear Regulatory Commission ("NRC") with respect to its nuclear power plants. NRC regulations govern the granting of licenses for the construction and operation of nuclear power plants and subject those power plants to continuing review and regulation.
The construction, planning and siting of Edison's power plants within California are subject to the jurisdiction of the California Energy Commission and the CPUC. Edison is subject to rules and regulations promulgated by the California Air Resources Board and local air pollution control districts with respect to the emission of pollutants into the atmosphere, the regulatory requirements of the California State Water Resources Control Board and regional boards with respect to the discharge of pollutants into waters of the state and the requirements of the California Department of Toxic Substances Control with respect to handling and disposal of hazardous materials and wastes. Edison is also subject to regulation by the U.S. Environmental Protection Agency ("EPA"), which administers certain federal statutes relating to environmental matters. Other federal, state and local laws and regulations relating to environmental protection, land use and water rights also impact Edison.
The California Coastal Commission has continuing jurisdiction over the coastal permit for San Onofre Nuclear Generating Station ("San Onofre") Units 2 and 3. Although the units are operating, the permit remains open. This jurisdiction may continue for several years because it involves oversight on mitigation measures arising from the permit.
The Department of Energy ("DOE") has regulatory authority over certain aspects of Edison's operations and business relating to energy conservation, solar energy development, power plant fuel use and disposal, coal conversion, public utility regulatory policy and natural gas pricing.
RATE MATTERS
CPUC Retail Ratemaking
The rates for electricity provided by Edison to its retail customers comprise several major components established by the CPUC to compensate Edison for basic business and operational costs, fuel and purchased power costs, and the costs of adding major new facilities.
Basic business and operational costs are recovered through base rates, which are determined in general rate case proceedings held before the CPUC every three years. During a general rate case, the CPUC critically reviews Edison's operations and general costs to provide service (excluding energy costs and, in certain instances, major plant additions). The CPUC then determines the revenue requirement to cover those costs, including items such as depreciation, taxes, cost of capital, operation, maintenance, and administrative and general expenses. The revenue requirement is forecasted on the basis of a specified test year. Following the revenue requirement phase of a general rate case, Edison and the CPUC proceed to a rate phase which allocates revenue requirements and establishes rate levels for customers.
Base rates may be adjusted in the years between general rate case years through an attrition year allowance. The attrition year allowance is intended to allow Edison to recover, without lengthy hearings, specific uncontrollable cost changes in its base rate revenue requirement and thereby preserve Edison's opportunity to earn its authorized rate of return in the years that are not general rate case test years.
In December 1993, Edison filed an application with the CPUC in which it proposed a performance-based ratemaking procedure for recovery of operation and maintenance ("O&M") expenses and capital-related costs. Such costs have traditionally been recovered through general rate cases, attrition proceedings, and cost of capital proceedings.
Edison proposed that the CPUC authorize a base rate revenue indexing formula which would combine O&M and capital-related cost recovery. In addition, Edison proposed that the period between general rate cases be lengthened from three to six years. Cost of capital proceedings would occur only after significant changes in utility capital markets.
Edison's fuel, purchased power and energy-related costs of providing electrical service are recovered through a balancing account mechanism called the Energy Cost Adjustment Clause ("ECAC"). Under the ECAC balancing account procedure, fuel, purchased power and energy-related revenues and costs are compared and the difference is recorded as either an undercollection or overcollection. The amount recorded in the balancing account is periodically amortized through rate changes which return overcollections to customers by reducing rates or collect undercollections from customers by increasing rates. The costs recorded in the ECAC balancing account are subject to review by the CPUC and allowed for rate recovery only to the extent they are found to be reasonable. Certain incentive provisions are included in the ECAC that can affect the amount of fuel and energy-related costs actually recovered. Edison is required to make an ECAC filing for each calendar year, and must also make a second filing for a mid-year adjustment if such filing would result in an ECAC rate change exceeding 5% of total annual revenue.
For Edison's interest in the three units of the Palo Verde Nuclear Generating Station ("Palo Verde"), the CPUC authorized a 10-year rate phase-in plan which deferred $200,000,000 of investment-related revenue
during the first four years of operations for each of the three units, commencing on their respective commercial operation dates. Revenue deferred for each unit under the plan for years one through four was $80,000,000, $60,000,000, $40,000,000 and $20,000,000, respectively. The deferrals and related interest are being recovered over the final six years of each unit's phase-in plan.
The CPUC has also adopted a nuclear unit incentive procedure which provides for a sharing of additional energy costs or savings between Edison and its ratepayers when operation of any of the units of San Onofre or Palo Verde is outside a specified target capacity factor ("TCF") range. For San Onofre Units 2 and 3, and Palo Verde Units 1, 2 and 3 the TCF range is 55% to 80% of their rated capacity.
The Electric Revenue Adjustment Mechanism ("ERAM") reflects the difference between the recorded level of base rate revenue and the authorized level of base rate revenue. This mechanism has been adopted by the CPUC primarily to minimize the effect on earnings of fluctuations in retail kilowatt-hour sales.
General Rate Case ("GRC")
In December 1991, the CPUC issued a decision on the revenue requirement phase of Edison's 1992 test year GRC application. The CPUC authorized a $72,000,000 or 1% increase in Edison's base rate revenues, effective January 20, 1992. The decision did not adopt Edison's request to capitalize, rather than expense, computer software development and research, development and demonstration ("RD&D") expenditures, but did allow Edison to file additional information regarding such capitalization.
In April 1992, Edison filed supplemental testimony supporting its request to capitalize application software development costs, and proposed to decrease its authorized level of base rate revenues ("ALBRR") by $53,000,000 in 1993 and 1994. Edison and the CPUC's Division of Ratepayer Advocates ("DRA") entered into a settlement agreement to allow rate recovery of capitalized software expenditures in which Edison agreed to an additional $32,000,000 base rate revenue decrease. The CPUC approved the settlement agreement in November 1992, and authorized a $48,900,000 decrease to Edison's ALBRR effective January 1, 1993. The related base rate revenue decrease was included in Edison's January 15, 1993, consolidated revenue change. The CPUC also authorized a $12,900,000 increase to Edison's ALBRR effective January 1, 1994. The related base rate revenue increase was included in Edison's January 24, 1994, consolidated revenue change.
In September 1992, Edison filed supplemental testimony supporting its request to capitalize RD&D expenditures. In the additional filing, Edison proposed to capitalize approximately $9,000,000 in RD&D project expenditures. The DRA's supplemental testimony alleged that Edison did not comply with a CPUC order regarding joint remote meter reading and recommended a $10,000,000 penalty for non-compliance. Additionally, the DRA proposed to disallow approximately $4,500,000 of capital costs associated with Edison's research on off-grid generation technology. The CPUC's decision is expected by the end of 1994.
In December 1992, the CPUC approved an ALBRR increase of $110,000,000, effective January 1, 1993, for the 1993 attrition year allowance. The related base rate revenue increase was included in Edison's January 15, 1993 consolidated revenue change. In April 1993, the CPUC modified its decision (pursuant to a petition by Edison), and approved an ALBRR increase of $10,400,000 effective April 28, 1993. The related base rate
revenue increase was included in Edison's January 24, 1994, consolidated revenue change.
In December 1993, the CPUC approved an ALBRR increase of $97,200,000 effective January 1, 1994, for: (1) the 1994 attrition year allowance; (2) increased federal income taxes pursuant to the Revenue Reconciliation Act of 1993; and, (3) reduction in Edison's California property tax liability resulting from a settlement agreement with the California State Board of Equalization.
Each year, the CPUC reviews the components of the cost of capital for all the California energy utilities in a generic cost of capital proceeding. On December 3, 1993, the CPUC issued a final decision resulting in a $108,000,000 reduction to Edison's ALBRR effective January 1, 1994. The decision also resulted in a reduction of Edison's overall rate of return from 9.94% to 9.17%, a reduction in return on common equity from 11.80% to 11.00%, and an increase to Edison's common equity capital ratio from 46.00% to 47.25% effective January 1, 1994. The related base rate revenue decrease was included in Edison's January 24, 1994, consolidated revenue change.
In December 1993, Edison filed with the CPUC its 1995 GRC application. In its application, Edison requested an increase to the ALBRR of $117,000,000 above the expected year-end 1994 ALBRR level to become effective January 1, 1995. On March 14, 1994, the DRA issued a report which, based on Edison's preliminary review, recommended a $269,000,000 reduction to Edison's expected year-end 1994 authorized level of base rate revenue. Evidentiary hearings are expected to commence in April 1994, with a final CPUC decision anticipated in December 1994.
In January 1994, the CPUC approved an ALBRR increase of $8,800,000 effective January 24, 1994, for base rate recovery of the permanent component of Edison's fuel oil inventory. The related base rate revenue increase was included in Edison's January 24, 1994, consolidated revenue change.
In November 1993, the CPUC approved an ALBRR increase of: (1) $64,400,000 effective December 31, 1993; and (2) $63,100,000 effective January 1, 1994, to reflect cost recovery of employee post-retirement benefits other than pensions ("PBOP"). In addition, the CPUC approved an ALBRR reduction of $39,500,000 effective December 30, 1993, to reflect the removal of costs associated with Edison's 1992 PBOP contributions. The related base rate revenue reduction associated with the PBOP ALBRR changes was included in Edison's January 24, 1994, consolidated revenue change, less $16,000,000 of rate recovery deferred until 1995.
Energy Cost Adjustment Clause
In January 1992, the DRA issued a report on the reasonableness of Edison's non-standard, non-affiliate qualifying facilities ("QF") power purchase contracts included in Edison's 1989 and 1990 annual ECAC applications. With respect to both ECAC periods, the DRA asserted that Edison had incorrectly calculated firm capacity payments and bonus capacity payments to QFs by including certain energy deliveries which the DRA contended should be excluded or "truncated" from the calculation. The DRA recommended disallowances of $2,500,000, for the 1989 record period and $4,800,000 for the 1990 record period. On April 26, 1993, the DRA withdrew its January 1992 testimony pursuant to an Edison-DRA agreement to jointly petition the CPUC for clarification of the CPUC's intent regarding truncation and two other QF contract administration issues. Edison and the DRA filed their joint petition on April 23, 1993. On November 2, 1993, the CPUC voted to dismiss the joint petition on the
basis that the issues presented were complex and could be developed more appropriately in an ECAC proceeding or through direct negotiations among the affected parties. Pursuant to the Edison-DRA agreement, a dismissal on this basis permits the DRA to renew its challenge to Edison's truncation practice beginning with the 1991 ECAC record period and thereafter in each subsequent ECAC record period. To date, the DRA has not recommended further disallowances attributable to the truncation issue.
In March 1992, Edison and the DRA settled disputes relating to Edison's power purchases from the 13 non- utility generation facilities partially owned by Mission Energy. Pursuant to the settlements, Edison agreed not to enter into new power-purchase contracts with Mission Energy and to a one-time disallowance. On March 10, 1993, the CPUC issued a decision approving the settlement and authorizing a ratepayer refund of $250,000,000 over a two-year period beginning January 1, 1994. The decision also ordered an immediate adjustment to Edison's ECAC balancing account with interest accruing until the rate reduction takes effect. The $250,000,000 disallowance is fully reflected in Edison's financial statements.
In October 1993, the DRA issued its report on QF reasonableness issues for the ECAC record period April 1990 through March 1991. In its report, the DRA recommended that the CPUC disallow $1,574,000 in power purchase expenses incurred as a result of purchases during the record period under a QF contract with Mojave Cogeneration Company, a nonutility generator. In its report, the DRA also alleged that in 1990 and 1991 Edison imprudently renegotiated Mojave Cogeneration Company's contract with Edison, resulting in higher ratepayer costs. The DRA further alleged that ratepayers may be harmed in the amount of $31,600,000 (present value) over the contract's twenty-year life. The DRA found the execution of five other QF contracts to be reasonable. Hearings will likely be held no earlier than the second half of 1994.
The DRA issued four reports addressing Edison's non-QF reasonableness showing for the April 1, 1991 through March 31, 1992 period. The DRA recommended: 1) a disallowance of $2,205,000 of replacement power costs associated with extended outage duration or reduced power production at Edison's nuclear units, which was allegedly caused by human error; and 2) a reduction of $1,203,000 to Edison's proposed TCF reward for San Onofre Unit 3, based on excluding generation above the unit capacity rating. A January 25, 1994 ALJ proposed decision found three nuclear plant outages unreasonable, resulting in a potential $1,600,000 disallowance, but rejected the DRA's recommendations for reducing Edison's TCF reward. Edison filed comments on the proposed decision on February 14, 1994. The final CPUC decision is expected in March 1994.
On May 28, 1993, Edison requested a $152,000,000 annual rate increase for service beginning January 1, 1994, for changes to the Energy Cost Adjustment Billing Factor, Electric Revenue Adjustment Balancing Accounts ("ERABF"), Low Income Surcharge and base rate levels. Edison also made a rate stabilization proposal which defers recovery of approximately $200,000,000 of 1994 fuel and purchased-power expenses until 1995. In July 1993, Edison updated its ECAC request to a $181,000,000 increase. The DRA proposed a $105,000,000 increase. In October 1993, Edison and the DRA stipulated to a proposed $164,688,000 ECAC revenue increase subject to adjustment for incorporating Edison's forecast December 31, 1993 balance in the ECAC, Low Income Ratepayer Assistance, and ERABF to reflect more recent recorded data. On January 19, 1994, the CPUC issued its decision which adopted a revenue increase of $274,600,000. When this revenue change is combined with other revenue changes which occurred on
or before January 1, 1994, the total combined revenue change is $232,101,000.
On May 28, 1993, Edison filed the non-QF portion of its Reasonableness of Operations Report, which included power purchases and exchanges and the operation of its hydro, coal, gas and nuclear resources for the period April 1, 1992 through March 31, 1993. In February 1994, the DRA recommended: (1) a $7,200,000 disallowance relating to fuel oil inventory management; and (2) a $5,000,000 disallowance for transmission loss revenues. Hearings on this matter are scheduled for October 1994.
Edison filed its QF Reasonableness of Operations Report on September 1, 1993. It is presently unknown when the DRA will file testimony in the QF reasonableness phase.
Palo Verde Outage Review
In March 1989, Palo Verde Units 1 and 3 experienced automatic shutdowns. Since the resultant outages overlapped previously scheduled refueling outages, normal refueling, maintenance, inspection, surveillance, modification and testing activities were conducted at the units, as well as modifications to the plants required by the NRC. Unit 3 was restored to service on December 30, 1989, and Unit 1 was restored to service on July 5, 1990.
In December 1989, the CPUC instituted an investigation into the outages pursuant to the California Public Utilities Code ("Code"). The Code requires the CPUC to institute an investigation when any portion of a utility's generating facilities has been out of service for nine consecutive months. The CPUC order required that the subsequent collection of rates associated with Palo Verde Units 1 and 3 be subject to refund pending review of the outages. In November 1991, the DRA issued a report recommending disallowances totaling more than $160,000,000 including a $63,000,000 disallowance for revenue collected during the outages (including interest).
In September 1993, Edison and the DRA agreed to settle these disputes for $38,000,000 (including $29,000,000 for replacement power costs, $2,000,000 for capital projects and approximately $7,000,000 for interest), subject to CPUC approval. The settlement resolves all issues related to the 1989-1990 outages at Palo Verde. The effect of the settlement has been fully reflected in the financial statements. Edison expects a CPUC decision regarding the settlement in mid-1994.
Mohave Order Instituting Investigation ("OII")
In April 1986, the CPUC began investigating the 1985 rupture of a high pressure steam pipe at the Mohave Generating Station ("Mohave"). Edison is the plant operator and 56% owner. The CPUC's OII reviewed Edison's share of repair costs and replacement fuel and energy related costs associated with the outage. Edison incurred costs of approximately $90,000,000 (including interest) to repair damage from the accident and provide replacement power during the six-month outage. This total is net of Edison's recovery of expenses from the settlement of lawsuits with contractors and insurance.
In May 1991, the DRA and its consultant issued reports alleging that Edison imprudently operated the Mohave plant and therefore contributed to the accident. As a result, the DRA recommended that all expenses incurred because of the accident be disallowed in rates. The DRA did not quantify
its proposed disallowance. Edison believes that metallurgical and physical characteristics of a weld reduced the otherwise expected pipe life to the point of failure after 15 years of service. Edison filed testimony contesting the allegations in May 1992, in December 1992, and on March 1, 1993. In March 1994, the CPUC issued a decision finding that Edison acted unreasonably in failing to implement an inspection program. The CPUC decision ordered a second phase of this proceeding to quantify the disallowance.
High Voltage Direct Current Expansion Project ("HVDCEP")
The HVDCEP began operation in 1989. In October 1989, Edison filed a report with the CPUC requesting recovery of $72,600,000 in project costs. Subsequently, Edison and the DRA agreed on an accounting adjustment of $150,000, and a settlement agreement was filed. A February 3, 1993 CPUC decision upheld the settlement agreement allowing Edison recovery in rates of approximately $72,450,000. In its 1995 GRC, Edison is requesting rate recovery of an additional $7,000,000 associated with completion items and other HVDCEP related expenditures. The total amount of rate recovery for the HVDCEP that Edison will be allowed remains subject to further adjustment pending a final determination of the cost-effectiveness of the project in comparison with the power exchange agreement between Edison and the Los Angeles Department of Water and Power.
FERC Resale Ratemaking
Edison sells electricity to public power utilities (the cities of Anaheim, Azusa, Banning, Colton, Riverside and Vernon), Southern California Water Company and Arizona Public Service Company ("APS") under rates subject to FERC jurisdiction. In accordance with FERC procedures, resale rates are subject to refund with interest if subsequently disallowed. Edison believes any refunds from pending rate proceedings, would not materially affect its results of operations or financial position.
FUEL SUPPLY
Fuel and purchased-power costs amounted to approximately $3.29 billion in 1993, a 7% increase over 1992. Sources of energy and unit costs of fuel for 1989 through 1993 were as follows:
_______________ (1) British Thermal Unit ("BTU") is the standard unit of measure for the heat content of fuels. One BTU is the amount of heat required to raise the temperature of one pound of water, at 39.1 degrees Fahrenheit, by one degree Fahrenheit.
(2) There are no fuel costs associated with these categories.
*Indicates a source of less than 1%
Average fuel costs, expressed in cents per kilowatt-hour, for the year ended December 31, 1993, were: oil, 7.996 cents; natural gas, 2.930 cents; nuclear, 0.537 cents; and coal, 1.226 cents.
Natural Gas Supply
Twelve of Edison's major steam electric generating units are designed to burn oil or natural gas as a primary boiler fuel. In 1990, Edison adopted an all-gas strategy to comply with air quality goals by eliminating burning oil in all but very extreme conditions. In August 1991, the CPUC adopted regulations which made Edison fully responsible for all gas procurement activities previously performed by local distribution companies for natural gas. To implement its all-gas strategy, Edison acquired a balanced portfolio of gas supply and transportation arrangements. Traditionally, natural gas needs in southern California were met from gas production in the southwest region of the country. To diversify its gas supply, Edison entered into four 15-year natural gas supply agreements with major producers in western Canada. These contracts, totaling 200,000,000 cubic feet per day, have market-sensitive pricing arrangements. This represents about 40% of Edison's current average annual supply needs. The rest of Edison's gas supply is acquired under short-term contracts from West Texas, New Mexico, and the Rocky Mountain region.
Firm transportation arrangements provide the necessary long-term reliability for supply deliverability. To transport Canadian supplies, Edison contracted for 200,000,000 cubic feet per day of firm transportation arrangements on the Pacific Gas Transmission and Pacific Gas & Electric Expansion Project connecting southern California to the low-cost gas producing regions of western Canada. Edison has a 30-year commitment to this project, construction of which was completed in late 1993. In addition, Edison has a 15-year commitment to 200,000,000 cubic feet per day of firm transportation rights on El Paso Natural Gas' pipeline to transport Southwest U.S. gas supplies.
Nuclear Fuel Supply
Edison has contractual arrangements covering 100% of the projected nuclear fuel cycle requirements for San Onofre through the years indicated below:
_______________ (1) Assumes the San Onofre participants meet their supply obligations in a timely manner.
(2) Assumes full utilization of expanded on-site storage capacity and normal operation of the units, including interpool transfers and maintaining full-core reserve. To supplement existing spent fuel storage, a contingency plan is being developed to construct additional on-site storage capacity with initial operation scheduled for no later than 2002. The Nuclear Waste Policy Act of 1982 requires that the DOE provide for the disposal of utility spent nuclear fuel beginning in 1998. The DOE has stated that it is unlikely that it will be able to start accepting spent nuclear fuel at its permanent repository before 2010.
Participants in Palo Verde have purchased uranium concentrates sufficient to meet projected requirements through 1997. Independent of arrangements made by other participants, Edison will furnish its share of uranium concentrates requirements through at least 1995 from existing contracts. Contracts to provide conversion services cover requirements through 1994. Enrichment and fabrication contracts will meet Palo Verde requirements through 1995 and 1997, respectively.
Palo Verde on-site expanded spent fuel storage capacity will accommodate needs through 2005 for Units 1 and 2 and 2006 for Unit 3, while maintaining full-core reserve.
ENVIRONMENTAL MATTERS
Legislative and regulatory activities in the areas of air and water pollution, waste management, hazardous chemical use, noise abatement, land use, aesthetics and nuclear control continue to result in the imposition of numerous restrictions on Edison's operation of existing facilities, on the timing, cost, location, design, construction and operation by Edison of new facilities required to meet its future load requirements, and on the cost of mitigating the effect of past operations on the environment.
These activities substantially affect future planning and will continue to require modifications of Edison's existing facilities and operating procedures. Edison is unable to predict the extent to which additional regulations may affect its operations and capital expenditure requirements.
The Clean Air Act provides the statutory framework to implement a program for achieving national ambient air quality standards and provides for maintenance of air quality in areas exceeding such standards. The Clean Air Act was amended in 1990, giving the South Coast Air Quality Management District ("SCAQMD") 20 years to achieve all the federal air quality standards. The SCAQMD's Air Quality Management Plan ("AQMP"), adopted in 1991, demonstrates a commitment to attain federal air quality standards within 20 years. Consistent with the requirements of the AQMP and the Clean Air Act Amendments of 1990 ("CAAA"), the SCAQMD adopted rules to reduce emissions of oxides of nitrogen ("NOx") from combustion turbines, internal combustion engines, industrial coolers and utility boilers. On October 15, 1993, the SCAQMD adopted the Regional Clean Air Incentives Market ("RECLAIM") which replaces most of the previous rule requirements with a market mechanism for NOx emission trading (trading credits). RECLAIM will, however, still require Edison to reduce NOx emissions through retrofit or purchase of trading credits on all basin generation by over 86% by 2003. In Ventura County, a NOx rule was adopted requiring more than an 88% NOx reduction by June 1996 at all utility boilers. Edison's expected total cost to meet these requirements is approximately $330,000,000 of capital expenditures.
The CAAA do not require any significant additional emissions control expenditures that are identifiable at this time. The amendments call for a five-year study of the sources and causes of regional haze in the southwestern U.S. The extent to which this study may require sulfur dioxide emissions reductions at the Mohave plant is not known. The acid rain provisions of the amended Clean Air Act also put an annual limit on sulfur dioxide emissions allowed from power plants. Edison will receive more sulfur dioxide allowances than it requires for its projected operations. The CAAA also require the EPA to carry out a three-year study of risk to public health from emissions of toxic air contaminants from power plants, and to regulate such emissions only if required. As a result of a petition by Mohave County in the State of Arizona, the Nevada Department of Environmental Protection ("NDEP") studied the impact of the plume from the Mohave plant on the Mohave area air quality. The regulatory outcome requires Edison to meet a new lower opacity limit in early 1994. The NDEP will review the opacity limit again in 1995 in conjunction with an ongoing tracer study being conducted by the EPA and evaluate potential impacts on visibility in the Grand Canyon from sulfur dioxide emissions. Until more definitive information on tracer study results are available, Edison expects to meet all the present regulations through improved operations at the plant.
Regulations under the Clean Water Act require permits for the discharge of certain pollutants into waters of the United States. Under this act, the EPA issues effluent limitation guidelines, pretreatment standards and new source performance standards for the control of certain pollutants. Individual states may impose even more stringent limitations. In order to comply with guidelines and standards applicable to steam electric power plants, Edison incurs additional expenses and capital expenditures. Edison presently has discharge permits for all applicable facilities.
The Safe Drinking Water and Toxic Enforcement Act prohibits the exposure to individuals of chemicals known to the State of California to cause cancer or reproductive harm and the discharge of such listed chemicals into potential sources of drinking water. Additional chemicals
are continuously being put on the state's list, requiring constant monitoring by Edison.
The State of California has adopted a policy discouraging the use of fresh water for plant cooling purposes at inland locations. Such a policy, when taken in conjunction with existing federal and state water quality regulations and coastal zone land use restrictions, could substantially increase the difficulty of siting new generating plants anywhere in California.
Edison has identified 42 sites for which it is, or may be, responsible for remediation under environmental laws. Edison is participating in investigations and cleanups at a number of these sites and has recorded a $60,000,000 liability for its estimated minimum costs to clean up several sites. Additional costs may be incurred as progress is made in determining the magnitude of required remedial actions, as Edison's share of these costs in proportion to other responsible parties is determined and as additional investigations and cleanups are performed.
The CPUC currently allows rate recovery of environmental-cleanup costs, subject to reasonableness reviews. Edison filed for a reasonableness review of costs incurred through 1991 at two hazardous substance sites. Hearings have been delayed due to a 1992 CPUC decision involving another California utility, which concluded that the current procedure may not be appropriate for these costs and requested interested parties to recommend alternatives. In November 1993, the major California utilities, the DRA and others filed a collaborative report recommending an incentive mechanism, which would require shareholders to fund 10% of cleanup costs. Shareholders would have the opportunity to recover these costs through insurance. Accordingly, Edison has recorded a regulatory asset which represents 90% of the estimated cleanup costs for sites covered by this proposed mechanism. The remaining sites' cleanup costs are expected to be immaterial and would be recovered through base rates. If approved by the CPUC, Edison would be allowed to recover 90% of cleanup costs incurred to date under the reasonableness review procedure ($11,000,000). A March 11, 1994 proposed decision issued by a CPUC ALJ accepted the collaborative report's recommendation. A final CPUC decision is expected in early 1994.
Twenty of the 42 sites identified are former manufactured gas plant sites. Edison's cleanup responsibility for these sites is based on Edison's, or a predecessor company's, ownership or operation of the plants. These gas plants were operated for the production of gas prior to the widespread availability of natural gas. The EPA and the California Department of Toxic Substances Control have determined that specified constituents of the gas plant by-products are hazardous substances or hazardous wastes, and may require removal or other remedial action.
The Resource Conservation and Recovery Act ("RCRA") provides the statutory authority for the EPA to implement a regulatory program for the safe treatment, recycling, storage and disposal of solid and hazardous wastes. There is an unresolved issue regarding the degree to which coal wastes should be regulated under RCRA. Increased regulation may result in an increase in expenses related to the operation of Mohave.
The Toxic Substance Control Act and accompanying regulations govern the manufacturing, processing, distribution in commerce, use and disposal of polychlorinated biphenyls, a toxic substance used in certain electrical equipment ("PCB waste"). Current costs for disposal of PCB waste are immaterial.
Edison's capitalized expenditures for environmental protection for the years 1969 through 1993 and its currently estimated capital expenditures for such purpose for the years 1994 through 1998 are as follows:
These estimates include budgeted and forecasted plant expenditures responsive to currently effective legislation. Projected capital expenditures for environmental protection are subject to continuous review and periodic revisions because of escalation in engineering and construction costs, additions and deletions of planned facilities, changes in technology, evolving environmental regulatory requirements and other factors beyond Edison's control. Edison believes that costs incurred for these environmental purposes will be recognized by the CPUC and the FERC as reasonable and necessary costs of service for rate recovery purposes.
ITEM 2.



ITEM 2. PROPERTIES
EXISTING GENERATING FACILITIES
Edison owns and operates 12 oil- and gas-fueled electric generating plants, one diesel-fueled generating plant, 38 hydroelectric plants and an undivided 75.05% interest (1,614 MW net) in Units 2 and 3 at San Onofre. These plants are located in central and southern California. Palo Verde (15.8% Edison-owned, 579 MW net) is located near Phoenix, Arizona. Palo Verde Units 1, 2 and 3 started commercial operation on February 1, 1986, September 19, 1986, and January 20, 1988, respectively. Edison owns a 48% undivided interest (754 MW) in Units 4 and 5 at the Four Corners Generating Station ("Four Corners Project"), a coal-fueled steam electric generating plant in New Mexico. Palo Verde and the Four Corners Project are operated by other utilities. Edison operates and owns a 56% undivided interest (885 MW) in Mohave, which consists of two coal-fueled steam electric generating units in Clark County, Nevada. Edison receives an entitlement of 277 MW from the DOE's Hoover Dam Hydroelectric Project. At year-end 1993, the existing Edison-owned generating capacity (summer effective rating) was comprised of approximately 67% gas, 14% nuclear, 11% coal and 8% hydroelectric.
San Onofre, the Four Corners Project, certain of Edison's substations and portions of its transmission, distribution and communication systems are located on lands of the United States or others under (with minor exceptions) licenses, permits, easements or leases or on public streets or highways pursuant to franchises. Certain of such documents obligate Edison, under specified circumstances and at its expense, to relocate transmission, distribution and communication facilities located on lands owned or controlled by federal, state or local governments.
With certain exceptions, major and certain minor hydroelectric projects with related reservoirs, currently having an effective operating capacity of 1,154 MW and located in whole or in part on lands of the United States, are owned and operated by Edison under governmental licenses which expire
at various times between 1994 and 2022. Such licenses impose numerous restrictions and obligations on Edison, including the right of the United States to acquire the project upon payment of specified compensation. When existing licenses expire, FERC has the authority to issue new licenses to third parties, but only if their license application is superior to Edison's and then only upon payment of specified compensation to Edison. Any new licenses issued to Edison are expected to be issued under terms and conditions less favorable than those of the expired licenses. Edison's applications for the relicensing of certain hydroelectric projects referred to above with an aggregate effective operating capacity of 89.0 MW are pending. Annual licenses issued for all Edison projects, whose licenses have expired and are undergoing relicensing, will be renewed until the new licenses are issued.
In 1993, Edison's peak demand was 16,475 MW, set on September 9, 1993. The 1993 peak was 1,938 MW less than Edison's record peak demand of 18,413 MW that occurred on August 17, 1992. Total area system operating capacity of 20,606 MW was available to Edison at the time of the 1993 record peak.
Substantially all of Edison's properties are subject to the lien of a trust indenture securing First and Refunding Mortgage Bonds ("Trust Indenture"), of which approximately $3.5 billion principal amount was outstanding at December 31, 1993. Such lien and Edison's title to its properties are subject to the terms of franchises, licenses, easements, leases, permits, contracts and other instruments under which properties are held or operated, certain statutes and governmental regulations, liens for taxes and assessments, and liens of the trustees under the Trust Indenture. In addition, such lien and Edison's title to its properties are subject to certain other liens, prior rights and other encumbrances, none of which, with minor or unsubstantial exceptions, affects Edison's right to use such properties in its business, unless the matters with respect to Edison's interest in the Four Corners Project and the related easement and lease referred to below may be so considered.
Edison's rights in the Four Corners Project, which is located on land of The Navajo Tribe of Indians under an easement from the United States and a lease from The Navajo Tribe, may be subject to possible defects. These defects include possible conflicting grants or encumbrances not ascertainable because of the absence of, or inadequacies in, the applicable recording law and the record systems of the Bureau of Indian Affairs and The Navajo Tribe, the possible inability of Edison to resort to legal process to enforce its rights against The Navajo Tribe without Congressional consent, possible impairment or termination under certain circumstances of the easement and lease by The Navajo Tribe, Congress or the Secretary of the Interior and the possible invalidity of the Trust Indenture lien against Edison's interest in the easement, lease and improvements on the Four Corners Project.
EL PASO ELECTRIC COMPANY ("EL PASO") BANKRUPTCY
El Paso owns and leases a combined 15.8% interest in Palo Verde and owns a 7% interest in Units 4 and 5 of the Four Corners Project. In January 1992, El Paso filed a voluntary petition to reorganize under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Western District of Texas. Pursuant to an agreement among the Palo Verde participants and an agreement among the participants in Four Corners Units 4 and 5, each participant is required to fund its proportionate share of operation and maintenance, capital and fuel costs of Palo Verde and Four Corners Units 4 and 5, respectively. The participation agreements provide that if a participant fails to meet its payment obligation, each non-defaulting participant must pay its proportionate share of the payments owed by the defaulting participant.
In February 1992, the bankruptcy court approved a stipulation between El Paso and APS, as the operating agent of Palo Verde, pursuant to which El Paso agreed to pay its proportionate share of all Palo Verde invoices delivered to El Paso after February 6, 1992. El Paso agreed to make these payments until such time, if ever, the bankruptcy court orders El Paso's rejection of the participation agreement governing the relations among the Palo Verde participants. The stipulation also specifies that approximately $9,200,000 of El Paso's Palo Verde payment obligations invoiced prior to February 7, 1992, are to be considered "pre- petition" general unsecured claims of the other Palo Verde participants.
On August 27, 1993, El Paso filed with the bankruptcy court an Amended Plan of Reorganization and Disclosure Statement ("Amended Plan"). The Amended Plan, which is subject to numerous conditions, proposes a reorganization pursuant to which El Paso will become a wholly-owned subsidiary of Central and South West Corporation. The Amended Plan also proposes, among other things, (i) rejection of the El Paso leases and reacquisition by El Paso of the Palo Verde interests represented by the leases, and (ii) El Paso's assumption of the Four Corners Operating Agreement and the Arizona Nuclear Power Project Participation Agreement. On November 19, 1993, the bankruptcy court approved a Cure and Assumption Agreement among El Paso and the Palo Verde Participants, in which El Paso shall (i) assume the Participation Agreement on the date the Amended Plan becomes effective, and (ii) cure its pre-petition default on the date the court approves the Order Confirming El Paso's Amended Plan. On December 8, 1993, the bankruptcy court confirmed El Paso's Amended Plan. Effectiveness of the Amended Plan is still subject to approval by numerous state and federal agencies. El Paso estimates that it will take about 18 months to obtain all necessary regulatory approvals.
CONSTRUCTION PROGRAM AND CAPITAL EXPENDITURES
In April 1992, the CPUC decided how Edison and other California utilities will meet their resource needs through 2002. The CPUC ruled that Edison must obtain 624 MW of new generation through competitive bidding. The decision required that 175 MW be reserved for renewables, such as wind, hydro and geothermal. The competitive bid solicitation was issued in August 1993 and suspended in December 1993 due to the discovery of a bidding anomaly that raised prices above those allowed by the rules of the solicitation. After the suspension, Edison requested the solicitation be cancelled because current forecasts show that Edison has no need for additional generating capacity until at least 2005.
From the solicitation results, Edison has estimated that the cost of these resources would be approximately $530,000,000 (present value in 1997 dollars). However, two events have occurred that should reduce Edison's cost exposure resulting from power purchases under this CPUC mandated process. First, on March 15, 1994, Edison and Kenetech Corporation, a potential winning bidder in Edison's solicitation, signed a memorandum of understanding for a wind resource power purchase. Contingent upon CPUC approval, Kenetech, under this proposed agreement, will provide lower cost resources than those potentially awarded through Edison's solicitation. Second, on March 16, 1994, the CPUC issued an interim decision that reduces Edison's solicitation by 25% and gives Edison authority to eliminate the added costs from the bidding anomaly. Although Edison will likely continue to request cancellation of the competitive solicitation, these two events reduce Edison's exposure. The exact amount of this reduction cannot be estimated until the methodology the CPUC intends for implementation of these changes is known.
Cash required by Edison for its capital expenditures totaled $1,040,000,000 in 1993, $787,000,000 in 1992 and $964,000,000 in 1991. Construction expenditures for the 1994-1998 period are estimated as follows:
Edison's construction program and related expenditures are continuously reviewed and periodically revised because of changes in estimated system load growth, rates of inflation, receipt of adequate and timely rate relief, the availability and timing of environmental, siting and other regulatory approvals, the scope of modifications required by regulatory agencies, the availability and costs of external sources of capital, the development of new technology and other factors beyond Edison's control.
Since the completion of San Onofre Units 2 and 3 and Palo Verde Units 1, 2 and 3, construction work in progress has been significantly reduced. The reduction in construction work in progress caused allowance for funds used during construction ("AFUDC"), which does not represent current cash income, to decline accordingly. Pre-tax AFUDC represented 5.7% of earnings for 1993.
In addition to cash required for construction expenditures for the next five years as discussed above, $1.3 billion is needed to meet requirements for long-term debt maturities, and sinking fund redemption requirements. The majority of these capital requirements are expected to be met by internally generated sources.
Edison's estimates of cash available for operations for the five years through 1998 assume, among other things, the receipt of adequate and timely rate relief and the realization of its assumptions regarding cost increases, including the cost of capital. Edison's estimates and underlying assumptions are subject to continuous review and periodic revision.
The timing, type and amount of all additional long-term financing are also influenced by market conditions, rate relief and other factors, including limitations imposed by Edison's Articles of Incorporation and Trust Indenture.
NUCLEAR POWER MATTERS
Although higher energy costs will be incurred for replacement generation during any periods the San Onofre and Palo Verde Units are not in operation, substantially all such costs will be included in future ECAC filings. Edison cannot predict what other effects, if any, legislative or regulatory actions may have upon it or upon the future operation of the San Onofre or Palo Verde Units or the extent of any additional costs it may incur as a result thereof, except for those that follow.
San Onofre Unit 1
On November 30, 1992, Edison discontinued operation of San Onofre Unit 1. The CPUC approved an agreement between Edison and the DRA which allows Edison recovery of its investment of approximately $350,000,000 (after deferred taxes), including an 8.98% rate of return, by August 1996.
The agreement does not affect Unit 1's decommissioning, scheduled to start in 2013. The estimated current-dollar decommissioning costs for Unit 1 have been recorded as a liability.
San Onofre Units 2 and 3
In 1974, the California Coastal Commission, as a condition of the San Onofre Units 2 and 3 coastal permit, established a three-member Marine Review Committee ("MRC") to assess the marine environmental effects caused by the Units. In August 1989, the MRC issued its final report which alleged, in part, that San Onofre Units 2 and 3 caused adverse effects to several species of marine life and to the environment.
Based on the MRC findings, the Coastal Commission in 1991 revised the coastal permit for Units 2 and 3 and required Edison to restore 150 acres of degraded wetlands, construct a 300-acre artificial kelp reef, and install fish behavioral barriers inside the Units' cooling water intake structure. Edison is currently in the process of planning and designing these projects, all of which must receive the approval of the Coastal Commission and state and federal resource and regulatory agencies. Current estimates place Edison's share of these capital costs at about $83,000,000 which is expected to be spent over the next 10 to 12 years.
Palo Verde Nuclear Generating Station
On March 14, 1993, APS, as operating agent, manually shut down Palo Verde Unit 2 as a result of a steam generator tube leak. Unit 2 remained shut down and began its scheduled refueling outage on March 19, 1993.
An extensive inspection of the Palo Verde Unit 2 steam generators was performed prior to the unit's return to service on September 1, 1993. APS determined that intergranular attack/intergranular stress corrosion cracking was a major contributor to the tube leak. APS is continuing its evaluation of the effects of possible steam generator tube degradation in all three units (six steam generators) and has instituted several avenues of study and corrective action.
Palo Verde Units 1, 2, and 3 will be operated at reduced power (85%) until the investigation and other associated activities are completed. APS expects to be able to return the units to full power after implementing corrective action.
Nuclear Facility Decommissioning
Edison's share of costs to decommission nuclear generation facilities is estimated to be $225,500,000 for San Onofre Unit 1; $280,900,000 for San Onofre Unit 2; $365,400,000 for San Onofre Unit 3; $50,200,000 for Palo Verde Unit 1; $49,800,000 for Palo Verde Unit 2; and $55,400,000 for Palo Verde Unit 3. These costs are all in 1993 dollars.
Edison is currently collecting $104,255,000 annually in rates for its share of decommissioning costs for San Onofre Units 1, 2 and 3 and Palo Verde Units 1, 2 and 3. As of December 31, 1993, Edison's decommissioning trust funds totaled approximately $853,000,000 (market value).
In accordance with the Energy Policy Act of 1992, Edison's recorded liability at December 31, 1993, of $72,300,000 represents its share of the estimated costs to decommission three federal nuclear enrichment facilities. This cost is based on San Onofre's and Palo Verde's past purchases of enrichment services and will be paid over 15 years. These costs are expected to be recovered through the ECAC procedure and from participants.
Nuclear Facility Depreciation
To reduce Edison nuclear facilities' capital cost effect on future customer rates, Edison has filed for a $75,000,000 per year accelerated recovery of its nuclear investments. To offset the increased cost recovery, Edison proposes to lengthen its recovery period for transmission and distribution assets. This proposal would have no significant effect on customer rates. The CPUC held hearings in October 1993 and Edison expects a decision in mid-1994.
Nuclear Insurance
Edison carries the maximum insurance coverage reasonably available to protect against losses from damage to its nuclear units and to provide some of its replacement energy costs in the unlikely event of an accident at any of its nuclear units. A description of this insurance is included in Note 10 of "Notes to Consolidated Financial Statements" incorporated herein. Although Edison believes an accident at its nuclear units is extremely unlikely, in the event of an accident, regardless of fault, Edison's insurance coverage might be inadequate to cover the losses to Edison. In addition, such an accident could result in NRC action to suspend operation of the damaged unit. Further, the NRC could suspend operation at Edison's undamaged nuclear units and the CPUC and FERC could deny rate recovery of related costs. Such an accident, therefore, could materially and adversely affect the operations and earnings of Edison.
NUCLEAR WASTE POLICY ACT
Under the Nuclear Waste Policy Act of 1982, Edison, acting as agent for the San Onofre participants, has entered into a contract with the DOE for disposal of spent nuclear fuel for San Onofre Units 1, 2 and 3. Under the terms of the contract, Edison is required to pay a quarterly fee of one mill per kilowatt hour to the DOE for net nuclear power generated and sold on and after April 7, 1983. During 1992, DOE implemented a refund process for overpayments to the Nuclear Waste Fund through credits against future quarterly payments.
For generation prior to April 7, 1983, the contract required payment of a one-time fee equivalent to one mill per kilowatt hour, plus accrued interest. The obligation for this one-time fee was being discharged by equal quarterly payments. In October 1992 and 1993, DOE credits arising from overpayments to the Nuclear Waste Fund were also applied to this obligation. In October 1993, this obligation was paid in full. Expenses associated with the disposal of spent nuclear fuel are recovered through the ECAC procedure and from participants.
COMPETITIVE ENVIRONMENT
Under various acts of Congress, federal power projects have been constructed in California and neighboring states. Municipally owned utilities, cooperative utilities and other public bodies have certain preferences over investor-owned utilities in the purchase of electric power provided by federally funded power projects and, in addition, have certain preferences over investor-owned utilities in connection with the
acquisition of licenses to build and/or operate hydroelectric power plants. Any energy which is or may be generated at these projects and transmitted for the account of such other utilities and public bodies over present or future government or utility-owned lines into the territory or markets served by Edison would result in a loss of sales by Edison.
Under the laws of California, utility districts may include incorporated as well as unincorporated territory. Such districts, as well as municipalities, have the right to construct, purchase or condemn and operate electric facilities. In addition, when a city owning an electric system annexes adjacent unincorporated territory which Edison has previously served, Edison may experience a loss of customers.
Edison's construction permits for San Onofre Units 2 and 3 contain certain conditions which require Edison (i) on timely notice, to permit privately or publicly owned utilities, including Edison's resale customers within or adjacent to Edison's service area, to participate on mutually agreeable terms in future nuclear units initiated by Edison, and (ii) to interconnect and coordinate reserves with, furnish emergency service to, sell bulk power to and purchase bulk power from, and provide certain transmission services for such utilities. Edison has also entered into agreements with certain of its resale customers which contemplate their possible participation in jointly owned generating projects initiated by Edison, and the integration of power sources acquired by each such customer, including the dispatching, reserve sharing, partial power-supply requirements and transmission service required in connection with such integrated operations. Pursuant to these agreements, two resale customers exercised an option to participate in Edison's ownership entitlement in San Onofre Units 2 and 3. Effective November 1977, Edison sold an undivided 3.45% interest in San Onofre Units 2 and 3 to these two resale customers for approximately $90,000,000. Effective September 1981, a further 1.5% interest in Units 2 and 3 was sold to one of these resale customers for approximately $50,000,000. In addition, since 1986, six of Edison's resale customers have acquired ownership interests in other generating sources and made purchases from other utilities in such amounts as to decrease Edison's revenues from resale cities from 4.4% to 1.6% of sales. This revenue loss has not had a substantial effect on Edison's business and opportunities.
The Public Utility Regulatory Policies Act of 1978 ("PURPA") has fostered the entry of nonutility companies into the electric generation business. Under PURPA, nonutility power producers are allowed to construct QFs for the production of electricity from certain alternative or renewable energy resources, and utilities are required to purchase the electrical output of these QFs at prices set pursuant to state regulations and, in the future, pursuant to a CPUC-approved competitive bidding process.
Edison is required by contracts and state regulation to continue to buy power generated by QFs, under long-term contracts negotiated earlier at prices that are most often higher than the power Edison can produce or purchase from other sources. Edison is presently managing contracts with QF developers to reduce ratepayer impacts and to more closely match Edison's needs with proposed development. Further, certain operators of QFs sell power they produce to large industrial and commercial customers of Edison from projects located on-site. Further loss of sales from such customers may be aggravated in the future as a result of attempts by these producers to gain access to a utility's transmission lines to sell power directly to retail customers now being served by that utility--an activity called "retail wheeling." Edison opposes any attempt to impose mandatory wheeling to Edison's retail customers.
In late 1992, Congress passed the Energy Policy Act of 1992. This Act creates a new class of Exempt Wholesale Generators ("EWGs") who are exempt from the restrictions otherwise imposed on utilities under the Public Utility Holding Company Act. The effect of this exemption is to facilitate the development of more independent third-party generators potentially available to satisfy utilities' needs for increased power supplies. However, unlike purchases from QFs, utilities have no statutory obligation to purchase power from EWGs. Furthermore, EWGs are precluded from making direct sales to retail electricity customers.
The Energy Policy Act also broadens the authority of the FERC to require a utility to transmit power produced by a wholesale producer to another utility. Municipal utilities are eligible applicants for such transmission service. However, the FERC is precluded from ordering a utility to transmit power from another entity directly to a retail customer. The authority of states to order such retail wheeling is unclear; but, to the extent such authority exists, it is explicitly preserved by the Energy Policy Act.
ITEM 3.

ITEM 3. LEGAL PROCEEDINGS
ANTITRUST MATTERS
In 1983, a public power utility, the City of Vernon, filed a complaint against Edison in the United States District Court for the Central District of California, alleging violation of certain antitrust laws. The complaint alleged that Edison engaged in anticompetitive behavior by restricting access to Edison transmission facilities and foreclosing Vernon from purchasing bulk power supplies from other sources. Vernon also alleged that Edison unlawfully designed its resale rates and claimed damages of approximately $60,000,000 before trebling. Edison filed three motions for Summary Judgment and the District Court entered final judgment in favor of Edison in August 1990. In October 1990, Vernon appealed the District Court decision to the Ninth Circuit Court of Appeals. In February 1992, the Court of Appeals affirmed the District Court's rulings on all issues but one, involving injunctive relief only, and remanded that issue back to the District Court for consideration. In July 1992, Vernon filed a writ of certiorari to the U.S. Supreme Court which was denied. On July 13, 1993, Edison and Vernon settled the remaining issue regarding injunctive relief. The settlement is part of a broader settlement of regulatory issues that was approved by the FERC on October 27, 1993.
On January 31, 1991, California Energy Company ("CEC") filed a lawsuit in United States District Court for the Northern District of California against SCEcorp, Edison, several nonutility subsidiaries, selected individuals, and Kidder, Peabody & Co. CEC alleged antitrust violations of the Sherman Act, conspiracy to interfere with contractual relations and common law unfair competition. CEC asked for treble damages (as proved at trial) for antitrust violations and compensatory and punitive damages for the pendent claims. Furthermore, CEC requested that SCEcorp divest itself of Mission Energy. On April 30, 1993, Edison and CEC reached a settlement which dismissed the lawsuit.
Transphase Systems, Inc. filed a lawsuit on May 3, 1993, in the United States District Court for the Central District of California against Edison and San Diego Gas & Electric Company ("SDG&E"). The complaint alleged that Transphase was competitively disadvantaged because it could not directly access the demand side management funds Edison collects from its ratepayers to fund conservation and demand side management activities and that the utilities willfully acquired and maintain monopoly power in the energy conservation industry. The complaint sought $50,000,000 in damages before trebling. Edison filed a motion to dismiss the complaint
on the grounds that it was without merit. The court granted Edison's motion on October 7, 1993, and denied plaintiffs the opportunity to replead the case. Plaintiffs have appealed to the Ninth Circuit Court of Appeals.
ENVIRONMENTAL LITIGATION
On November 8, 1990, an environmental organization and two individuals filed a lawsuit against Edison in United States Federal District Court for the Southern District of California. The lawsuit alleges Edison's operation of San Onofre Units 2 and 3 is in violation of its National Pollutant Discharge Elimination System permits. The basis for the allegations was a report prepared for the California Coastal Commission on the marine environmental effects of the generating station. The plaintiffs requested that the Court enjoin operation of Units 2 and 3, impose civil penalties, and order Edison to repair the alleged damage to the marine environment. After mediation by the court, the parties agreed on a settlement that includes: (i) $2,000,000 in wetlands research which will be undertaken by the Pacific Estuarine Research Laboratory at San Diego State University; (ii) $7,500,000 in additional wetland restoration within the San Dieguito River Valley; (iii) a $5,500,000, 10 year, Marine Education Program which will be based at Edison's Redondo Generating Station; and (iv) $1,400,000 in attorney's fees. The court approved the settlement on June 15, 1993.
On September 23, 1993, the California Department of Toxic Substances Control ("DTSC") issued a Report of Violation to Edison, alleging various hazardous waste violations of the California Health & Safety Code at several Edison facilities. Edison is currently in settlement negotiations with DTSC regarding these alleged violations and tentatively has reached an agreement in principle for settlement in the amount of $1,900,000.
SAN ONOFRE PERSONAL INJURY LITIGATION
In 1993, a former NRC inspector who was assigned to San Onofre in 1985 and 1986 filed a lawsuit against Edison, SDG&E and a fuel rod manufacturer in Los Angeles County Superior Court, Central District. The case was subsequently transferred to the Federal District Court for the Southern District of California. The inspector claimed that exposure to radioactive materials at the plant caused her leukemia. Plant records showed that the inspector's exposure to radiation was well below NRC regulatory levels. Plaintiff nevertheless alleged that she was exposed to radioactive fuel particles, that this caused a radiation exposure above the NRC levels and that this exposure was a legal cause for her illness. Plaintiff sought compensatory and punitive damages. The defendants denied having liability for plaintiff's illness.
A jury trial began on January 4, 1994. In closing arguments at the end of the trial, plaintiff's counsel requested damages between $4,000,000 and $4,500,000 for medical costs and economic losses and asked for three to five times that amount for pain and suffering compensatory damages. After deliberations, the jury reported that it was "hung" and could not reach a unanimous verdict on the threshold question of whether plaintiff was exposed to radiation levels above the NRC-defined levels. (A 7-2 majority of the jury had concluded that plaintiff's exposure did exceed these levels). Finding itself hung on the exposure question, the jury did not decide the other questions regarding causation, the amount of compensatory damages and whether Edison's conduct warranted punitive damages. If the jury had found that punitive damages should be assessed, the trial would have resumed to decide the amount of such damages.
On February 8, 1994, the trial judge declared a mistrial because of the hung jury. The second trial was scheduled to begin on March 15, 1994. On March 14, 1994, the case was settled. The amount of the settlement payment will not have a material adverse effect on Edison's net income.

We have audited, in accordance with generally accepted auditing standards, the consolidated financial statements included in the 1993 Annual Report to Shareholders of Southern California Edison Company, incorporated by reference in this Form 10-K, and have issued our report thereon dated February 4, 1994.
