(Electric Operations)
Of the 234 communities served with electricity, Dubuque, Iowa, is the largest with a population of approximately 58,000. Other major cities served are Albert Lea, Minnesota and Clinton and Mason City, Iowa. The remainder of the communities served are under 15,000 population, of which 193 or 84% are less than 1,000 population. The company sells electricity at wholesale to 19 small communities which have municipal distribution systems, 13 of which are total requirements customers, and 6 of which are partial requirements customers.
The territory served with electricity at retail by the company is a residential, agricultural and widely diversified industrial area with an estimated population of 338,000.
There have been no significant changes since the beginning of the fiscal year in the kind of products produced, services rendered, markets or method of distribution.
The facilities owned or operated by the company include facilities for the transmission of electric energy in interstate commerce or the sale of electric energy at wholesale in interstate commerce.
(Sources and Availability of Raw Materials)
Electricity generated by the company in 1993 was 93.5% from coal as a fuel, 0.1% from oil and 6.4% from natural gas. In 1994, the sources of such generation are estimated to be: 98.2% from coal, 0.2% from middle distillate oils, and 1.6% from natural gas. In 1993, 80.9% of the company's coal requirements came from long-term contracts. In 1994, the company anticipates that 83.8% of its coal requirements will be from long-term contracts. These contracts have expiration dates ranging from December 31, 1994 through December 31, 1998.
The company in 1990 negotiated the buyout of a 300,000 ton per year contract for Montana coal. See Note 9 to the Financial Statements of the Annual Report to Stockholders (EX-13) regarding recovery of contract cancellation costs.
The company has two 5 year contracts effective January 1, 1990 through December 31, 1994, for a total of 500,000 tons per year of 2% sulfur Midwestern coal for its Kapp #2, a 217 MW unit at Clinton, Iowa because of sulfur dioxide restrictions mandated by the State of Iowa.
The company has a contract for 150,000 tons of coal, 50,000 tons for Lansing Units #1, #2 and #3 and 100,000 tons for Dubuque, which expires at December 31, 1994.
The company has a contract for 500,000 tons per year for its 260 MW Lansing #4 unit. Lansing Unit #4 requires low sulfur coal, which is being purchased in the Powder River Basin of Wyoming. The company has this coal shipped by rail and then transloaded to barge, using facilities near Keokuk, Iowa. A contract with Orba-Johnson Transshipment Company, Inc., covers rail to barge coal transloading. Coal required for the company's generation by Neal #4 unit, located near Sioux City, Iowa is contracted for by the operator, Midwest Power Systems, under terms of the Unit Participation Agreement. Similar arrangements prevail with respect to the company's participation in Louisa #1 located near Muscatine, Iowa and operated by Iowa-Illinois Gas and Electric Company.
The company owns 120 coal cars, has an undivided ownership (21.528%) in 372 coal cars in connection with Neal #4. During February 1993, 21 coal cars were damaged or destroyed beyond repair. Nine of these cars have been repaired and 12 have been replaced. The company was reimbursed by the railroad carrier for all costs of repair or replacement. The company has an undivided ownership (4%) in 136 cars in connection with Louisa #1. Coal requirements in 1994 will require using leased cars for the Louisa #1 coal supply.
The company burned 665,952 gallons of No. 2 and No. 6 oil in 1993 and has 6,477,000 gallons of oil storage capacity in which to store adequate reserves during periods of high demand on refineries. The company relies on spot purchases of oil.
The company presently has interruptible natural gas available for its electric generation station at Clinton, Iowa through Natural Gas Pipeline Company of America. At the Fox Lake and Dubuque plants, interruptible gas is available through Peoples Natural Gas Company. There is no assurance that interruptible gas will continue to be available as fuel for electric generating plants.
(Duration and Effect of Electric Patents and Franchises)
The company owns no patents.
The company has, in the opinion of its legal counsel, all necessary franchises or other rights from the incorporated communities and other governmental subdivisions now served, required for the operation of its properties. With 196 electric franchises in effect in cities and villages, and with the majority of such franchises being for a term of 25 years, the renewal of such franchises is a continuing process. Thirty-two percent (62) of the franchises have been secured since January 1, 1984.
(Electric Seasonal Business)
The effects of air conditioning in summer and heating in winter have a seasonal impact on the business of the registrant. The air conditioning sales in the summer months are primarily related to the residential and commercial customer classes, however, the company does not meter air conditioning sales separately. During the past five years, the highest and lowest average residential consumption in the peak summer month has been 891 Kwh (July 1991) and 560 Kwh (June 1989), respectively, compared to 811 Kwh (January 1991) and 635 Kwh (February 1990) during the peak winter month. Refer to the section (Electric Governmental Regulations) for discussion of Iowa seasonal rates.
(Working Capital Items)
Three of the company's generating stations are located on the Mississippi River at Clinton, Dubuque and Lansing, Iowa, with their coal supply being delivered by barge during the barging season (approximately April 1st to December 1st). Coal in the stockpile at December 1st of each year has been sufficient to supply the normal requirements of these generating stations until the reopening of the Mississippi River for barge traffic. Coal shipments to the company's Neal #4 and Louisa #1 generating stations are able to continue year-round because river transportation is not involved.
(Electric Governmental Regulations)
The company filed an application with the IUB in September 1991 which requested an electric rate increase of $22.4 million. Interim rates of $16.2 million were placed in effect in May 1992 subject to refund. In July 1992, the IUB granted an annual revenue increase of $9.0 million (with an additional $1.4 million over the 12 months beginning November 1992 to recover costs related to a coal contract buyout). Revenue collected in excess of the IUB ordered level in the amount of $3,835,000 plus $236,000 of interest was reserved in 1992 and refunded in February 1993.
On May 26, 1993, the IUB approved electric tariffs which more closely track costs incurred by the company. Individual customers experienced an increase or decrease in their electric bill, but the adoption of the new tariffs did not change the company's overall revenue. The new tariffs, which were implemented in August 1993, give greater weight to the demand component of electric usage, and include a provision for a higher rate during the summer cooling season (June - September), and a lower rate during the remainder of the year. Due to implementation of the seasonal rates, revenue for the third and fourth quarters of 1993 is not comparable to the corresponding quarters of prior years.
The company filed an Iowa electric rate increase application on May 14, 1993. The IUB ruled on June 4, 1993 that the company's rate design docket approved by the IUB on May 26, 1993 constituted a change in rates. Thus, pursuant to a section of the Iowa Code which limits a utility to one rate application at a time, the rate filing was rejected. The company refiled in August 1993. The revised application requested an annual increase of $11.5 million, including a return on common equity of 12.35%. Interim rates in an annual amount of $11.0 million, which include a provision to recover SFAS 106 costs, were placed in effect on October 28, 1993, subject to refund. A decision on the rate increase is expected by the end of the second quarter of 1994.
The company filed an application with the MPUC in August 1991. The application requested an electric rate increase of $8.0 million. The MPUC allowed an interim increase of $4.2 million effective October 1991. In June 1992, the MPUC issued an order granting an annual revenue increase of $4.9 million, and a return on common equity of 10.9%. The MPUC order stated that the company has 100 MW of excess capacity and disallowed recovery of $1.9 million per year applicable to the excess capacity. In instances where final rates are higher than interim rates, Minnesota law allows the utility to recover the difference. Settlement rates, including a temporary increase to recover the difference between the interim and final rates over a six month period ending May 1993, were placed into effect in December 1992. In May 1993, the Minnesota Court of Appeals affirmed the MPUC order.
In June 1992, sixteen municipal wholesale customers filed a Complaint and Request for Investigation and Hearing with FERC. The complaint alleges that the company had been imprudent by entering into certain long-term coal contracts, an associated transloading agreement, and a rail transportation agreement and seeks recovery in the range of approximately $3 million to $7 million. The issue will be presented before an administrative law judge, with hearings currently scheduled to commence in August 1994. The decision by the administrative law judge is expected to be presented to the full Commission in 1995. Under this process an appeal of the FERC decision most likely would not occur until 1996 or later.
The company's electric rate tariffs provide for recovery of the cost of fuel through energy adjustment clauses, which clauses are subject to revision from time to time by the regulatory authority having jurisdiction. These clauses are designed to pass on to the consumer the increases or decreases in the cost of fuel without formal rate proceedings. Purchased capacity costs are not recovered from customers through energy adjustment clauses, but rather must be addressed in base rates in a formal rate proceeding. In the company's 1991 Iowa electric rate case, the IUB required that any jurisdictional revenue from capacity sales to other utilities be returned to Iowa customers through the fuel adjustment clause.
(Electric Competitive Conditions)
In 1993 the Illinois Commerce Commission entered an order determining that Interstate, and not Jo-Carroll Electric Cooperative, had the right to provide electric service to a large new freezer service plant near East Dubuque, IL. The company is providing service to that plant pursuant to Commission order. Jo-Carroll filed for judicial review of the Commission's action in a proceeding now pending in the Illinois 15th Judicial Circuit.
The Energy Policy Act of 1992 (Act) allows FERC to order utilities to grant access to transmission systems by third-party power producers. The Act specifically prohibits federally-mandated wheeling of power for retail customers. The company's industrial rates generally compare favorably with those of neighboring utilities. For the company's six largest industrial customers, the aggregate 1993 rate was approximately 3.4 cents per KWH. This rate also compares favorably with that of potential independent power producers and electric wholesale generators. The company's favorable rates reduce any incentive that these customers might otherwise have to relocate, self-generate or purchase electricity from other suppliers.
The company has no competition from the same type of public utility service in the sale of electricity in any of the incorporated communities served by it. Interstate may be subject to competition in unincorporated areas. In the States of Iowa, Illinois and Minnesota, territorial laws govern the question of possible service to customers in such unincorporated areas, and such laws regulate competition in such areas. Laws and statutory regulations in the different states in which service is rendered provide, under varying terms and conditions, for municipal ownership of electric generating plants and distribution systems. Certain franchises under which utility service is rendered give the municipality the right to purchase the system of the company within said municipality upon certain terms and conditions. However, no such purchase option and no right of condemnation of the company's properties has been exercised and no municipal generating plant or municipal distribution system has been established in the territory now served by the company during the past twenty-five years.
The Iowa Utilities Board, the Illinois Commerce Commission and the Minnesota Public Utilities Commission have each approved tariffs that allow the company to offer interruptible electric service for qualifying customers. The availability of this service provides price incentives to those customers having the ability to interrupt their connected load. The primary objective of the incentives is to reduce the system peak. The incentives also serve to retain existing customers and attract new customers.
(Other Sources of Power)
The company has been a participant in the Mid-Continent Area Power Pool (MAPP) Agreement since March 31, 1972. MAPP had a total coincident 1993 summer peak of 23,290 MW at which time the net capacity of the pool was 30,345 MW.
Membership in the pool permits sharing of reserve capacities of the members which affects reductions in plant facilities investment for MAPP members. The minimum reserve margin for participants in MAPP has been established at 15%.
Parties to the MAPP Agreement include, as participants, 29 electric power suppliers consisting of 10 investor-owned utilities, the United States Department of Interior (Western Area Power Administration), a Canadian system, public power districts and rural electric generating and transmission cooperative associations, municipal electric supply agencies and, as associate participants, 14 other electric power suppliers operating in Canada and in the North Central region of the United States. The pool coordinates planning and operation of power suppliers in Minnesota, Wisconsin, Montana, Iowa, Nebraska, North Dakota and South Dakota and provides reliability and economy for the company's bulk power supply. The MAPP Agreement was filed with the FERC and accepted as an initial rate filing effective December 1, 1972 and has been in operation since that time.
In addition to MAPP, the company has interchange connections with certain Missouri and Illinois utilities through 345 KV transmission systems. Future interconnections are planned to meet transmission requirements for the next ten years.
The company's total capacity includes three long-term power purchase contracts with area electric utilities. The contracts provide for the purchase of 230 to 255 megawatts of capacity over the period from May 1992 through April 2001. The company is obligated to pay the capacity charges regardless of the actual electric demand by the company's customers. Energy is available at the company's option at approximately 100% to 110% of monthly production costs for the designated units.
The three power purchase contracts required capacity payments of approximately $24.1 million in 1993. Over the remaining period of the contracts, total capacity payments will be approximately $180 million.
Capacity costs are not recovered from customers through energy adjustment clauses, but rather must be addressed in base rates in a formal rate proceeding. The IUB order in the company's 1991 rate case indicated that the capacity purchases were prudent and allowed recovery of the costs in rates. A 1992 rate order by the MPUC stated that the company has 100 MW of excess capacity and disallowed recovery of $1.9 million per year applicable to the excess capacity. The Minnesota Court of Appeals affirmed the MPUC disallowance in May 1993. The company has not yet filed for rate recovery in the Illinois and FERC jurisdictions.
The company has contracts with several governmental power agencies whereby the company provides transmission service to their customer/members. During 1993, the company received $1,183,588 for transmission service to customers of the Western Area Power Administration (WAPA), and $1,233,863 from Cooperative Power Association (CPA) for wheeling power to nine of its member distribution cooperatives.
The company's contract with CPA also provides for payment by the company for needed mutually utilized facilities constructed and owned by CPA. During 1993, these payments amounted to $330,319.
The company and Southern Minnesota Municipal Power Agency (SMMPA) have agreed by contract to compensate each other if over/underinvestment in the shared transmission system occurs. During 1993, SMMPA made payments to the company in the amount of $535,342.
The company's contract with Central Iowa Power Cooperative (CIPCO) provides for compensation to each other if over/underinvestment in the shared transmission system occurs. During 1993, the company owed CIPCO $63,259 for underinvestment in the Liberty Substation property. Also during 1993, CIPCO owed to the company $46,730 for underinvestment in the Dubuque-Clinton project. The net payment by the company to CIPCO totalled $16,529.
(Other Electric Operations)
The 1993 peak of 927,366 KW occurred on August 26, 1993 between 3:00 and 4:00 in the afternoon. At the time of its 1993 peak the company had a net effective electric capability of 1,295,600 KW. Of this net effective capability at the time of peak, 898,300 KW was in steam generation, 113,500 KW was in combustion turbine and the balance was in internal combustion units and purchases. The previous historical system net peak load for a sixty-minute period, of 919,100 KW, was reached on August 16, 1988.
(Gas Operations)
The company supplies retail gas service in 39 communities and serves approximately 48,000 gas customers.
There have been no significant changes since the beginning of the fiscal year in the kind of products produced, markets or methods of distribution.
(Gas Sources and Availability of Raw Materials)
The natural gas industry was recently restructured as a result of Order 636, issued by the Federal Energy Regulatory Commission (FERC) on April 8, 1992. This Order requires the interstate pipelines to provide transportation capacity unbundled (separated) from the sales of gas supply, as well as to provide open access to their storage facilities. The company no longer purchases a bundled gas supply from Northern Natural Gas Company (NNG) and Natural Gas Pipeline Company of America (NGPL). The company purchases pipeline capacity (space) from these companies to deliver a gas supply purchased from others. As of November 1, 1993 the company purchased gas from six non-traditional suppliers, such as producers, brokers, marketers, etc., at market responsive rates. The FERC continues to approve the tariffs of NNG and NGPL, but only with regard to capacity and storage rates, subject to change as rate cases are filed.
A section of the Order permits the interstate pipelines to pass on industry transition costs to their customers. Transition costs are comprised of gas supply realignment costs, unrecovered gas cost, stranded costs and new facilities costs. As a customer of NGPL and NNG, Interstate will be subject to a share of those costs. The FERC has approved the Order 636 Settlement between NNG and its customers; NGPL's Settlement is still being negotiated with its customers.
Gas for the company's Mason City, Albert Lea and Savanna service areas is transported by NNG under capacity contracts for 36,533 Mcf daily, and for an additional 15,657 Mcf in the November to March time frame. The majority, 27,194 Mcf, of the above capacities is from the producing areas of New Mexico, Oklahoma and Texas, etc. These contracts expire in October, 1997. Gas is supplied by other producers, marketers and brokers as well as from storage services to meet the peak heating season requirements. The company had 20,363 Mcf/d of storage, with the necessary pipeline capacity, available for the 1993-1994 heating season.
Gas for its Clinton service area is transported by NGPL under capacity contracts for 19,781 Mcf annually, with expiration dates of December 1, 1995 (6,949), February 28, 1996 (5,000), and November 30, 1996 (7,832). This gas is supplied by other producers, marketers and brokers. The company supplements this capacity with storage gas, which has the pipeline capacity embedded in its FERC approved rate. The company had 18,613 Mcf of storage available for the 1993-1994 heating season.
During 1993 the company utilized approximately 42.2% of its annualized daily contract gas available from its firm suppliers. The Company's total throughput level of 34,008,768 Mcf represents a 5.6% increase for 1993 as compared to 1992. The total throughput was composed of sales gas (20.1%), spot gas (9.4%) and customer transportation gas (70.5%).
During 1993 nineteen of Interstate's customers transported a total of 23,994,891 Mcf of their own gas over the company's pipeline and distribution systems. This reflects an increase over 1991 and 1992 in the number of customers exercising the transportation option. In 1991, fourteen of Interstate's customers transported a total of 16,055,921 Mcf, and in 1992 sixteen customers transported a total of 23,547,107 Mcf. The customer owned gas was delivered by interstate pipeline companies for those customers' accounts at Interstate's town border stations, under terms and conditions in tariffs approved by respective state commissions. Company policy is to assist any customer in exploring its options relative to purchasing gas directly from the producing sector. The company owns propane-air gas plants at Albert Lea, Minnesota and Clinton and Mason City, Iowa. The daily output capacities are: 5,500 Mcf, 4,000 Mcf and 9,600 Mcf of propane-air mix gas, respectively.
The requirement for gas on the peak winter day of the 1992-1993 season was 139,877 Mcf, including both firm and interruptible customers. This peak consisted of 29.0% jurisdictional sales gas, 1.4% spot gas, 51.6% customer purchased gas, 6.4% firm transportation service and 11.6% storage gas. Propane-air from the company's peak- shaving plants was not needed to meet demands due to the adequate gas supply. The maximum daily firm gas sales during the 1992-1993 season were as follows: Albert Lea 10,611 Mcf; Savanna 2,338 Mcf; Clinton 20,970 Mcf; Mason City 26,494 Mcf, or 43.2% of the peak winter day throughput.
The direct purchase of approximately 3,408,561 Mcf of natural gas in the spot market has resulted in a savings of $1,495,860 in the cost of natural gas during 1993. These savings have been passed on to the customers through the company's purchased gas adjustment clause.
(Duration and Effect of Gas Patents and Franchises)
The company owns no patents.
The company has, in the opinion of its legal counsel, all necessary franchises or other rights from the incorporated communities and other governmental subdivisions now served, required for the opera- tion of its properties. With 34 gas franchises in effect in cities and villages, and with the larger majority of such franchises being for a term of 25 years, the renewal of such franchises is a continu- ing process. fifty percent (17) of the franchises have been secured since January 1, 1984.
(Gas Seasonal Business)
The effects of heating sales to the residential and commercial classes of customers have a significant seasonal impact on the business of the registrant. The heating sales in the winter months account for 98% of the total annual sales to these classes of custom- ers. The average consumption for a residential customer during the peak winter months is 18.5 Mcf compared to the average of 2.6 Mcf during the summer. The average consumption for a commercial customer during the peak winter months is 90.7 Mcf compared to the average of 13.4 Mcf during the summer.
(Gas Governmental Regulations)
In November 1992 the company filed an application with the IUB for an increase in gas rates in an annual amount of approximately $4.1 million. Interim rates were placed in effect in February 1993. Additional interim rates in an annual amount of $300,000 were placed in effect in May 1993 after the IUB approved the company's trust agreement arrangements for additional postretirement benefits expense to be recognized under SFAS 106. On August 31, 1993, the IUB issued a final order allowing an annual increase of $3.3 million. Due to customers subsequently shifting to alternate tariffs, the company estimates that it will realize an annual increase of $2.8 million.
(Gas Competitive Conditions)
The company has no competition from the same type of public utility service in the sale of gas in any of the incorporated communities service by it. Certain major industrial customers of the company have taken advantage of Federal and State regulations to purchase their own gas supply from producers and have that gas transported by the company as described in the "Gas Sources and Availability of Raw Materials" section. Laws and statutory regulations in the different states in which service is rendered provide, under varying terms and conditions, for municipal ownership of distribution systems. Certain franchises under which utility service is rendered give the municipality the right to purchase the system of the company within said municipality upon certain terms and conditions. However, no such purchase option and no right of condemnation of the company's properties has been exercised and no municipal distribution system has been established in the territory now serviced by the company during the past twenty-five years.
(Dependence of Segment Upon a Single Customer)
In 1993, 1992 and 1991, the company had no single customer or indus- try for which electric and/or gas sales accounted for 10% or more of the company's consolidated revenues. In 1993, the company's three largest industrial customers accounted for 1,288,415,514 Kwh of electric sales ($42,000,742) and 21,950,299 Mcf of gas sales and transportation ($2,905,935).
(Research and Development)
The company has no full-time professional employees engaged in research activities and had no company-sponsored research programs during 1993, 1992 and 1991. In the public utility industry, research is commonly and traditionally done by manufacturers of equipment, trade organizations to which the company belongs, and university research programs. In 1993 approximately $1,089,599 was paid for research activities compared with $1,012,150 in 1992 and $955,862 in 1991.
(Electric and Magnetic Fields)
The possibility that exposure to electric and magnetic fields emanat- ing from power lines and other electric sources may result in adverse health effects has been a subject of increased public, governmental and media attention. A considerable amount of scientific research has been conducted on this topic with no definitive results. Re- search is continuing. It is not possible to tell what, if any, impact these actions may have on the company's financial condition.
(Environmental Regulations)
The company is subject to environmental regulations promulgated and enforced by federal and state governments. The company believes that it presently meets existing regulations. The Federal Clean Air Act Amendments of 1990 will require reductions in sulfur dioxide and nitrogen oxide emissions from power plants. The legislation sets two deadlines for compliance, Phase 1 (January 1, 1995) and Phase 2 (January 1, 2000). The most restrictive provisions relate to sulfur dioxide emissions. During Phase 1, only one of the company's units is affected. That unit's net effective capacity is 217 MW. Present plans for the affected unit are to switch to lower sulfur coal and install low nitrogen oxide burners. Phase 2 compliance will require addition- al capital, operating and maintenance costs beyond those required for Phase 1. The Phase 2 regulations will affect approximately 87% of the company's current generating capacity.
The company's long-range construction forecast (through the year 2000) contains estimated Phase 1 capital expenditures of approximate- ly $6.5 million and estimated Phase 2 capital expenditures in the range of $35.0 million. Estimated expenditures for 1994 and 1995 include $10.9 million for facilities necessary to comply with the Clean Air Act. The estimated expenditures include provisions for low nox burners, emission monitors, and flue gas conditioning systems. The company anticipates the costs of compliance with the Clean Air Act will be recovered through the ratemaking process.
The United States EPA, via the Clean Water Act, and the states have promulgated discharge limits necessary to meet water quality stan- dards. A National Pollutant Discharge Elimination System (NPDES) permit is required for all discharges. The company has current NPDES permits for all discharges and meets or or falls within the required discharge limits.
Early this century, various utilities including the company operated plants which used coal, coke and/or oil to produce manufactured gas for cooking and lighting. These facilities were abandoned 40 to 60 years ago when natural gas pipelines were extended into the upper Midwest. Some of the former gasification sites contain waste products which may present an environmental hazard. Waste remediation costs can vary significantly, dependent on the disposal method and type of contaminants. Current estimates range from $75 to $1,200 per ton of waste material.
In 1957, the company purchased facilities in Mason City, Iowa from Kansas City Power & Light company (KCPL) which included a parcel of land previously used for coal gasification. In 1986 and again in 1991, the company entered into Consent Orders with the Environmental Protection Agency (EPA) which obligate the company to conduct a Remedial Investigation and Feasibility Study at the Mason City site. A Remedial Investigation has been completed and has been approved by the EPA. The company is continuing to perform investigative testing to determine the limits of potential groundwater contamination at the Mason City site. The remediation process will not begin until the EPA has approved the scope of the project and the appropriate process for cleaning up the site. To-date, a total of 1,200 tons of contaminated soil has been identified. To-date, all costs have been charged to expense. The company spent $300,000 on the Mason City project in 1993; it has spent $1.7 million on the site since the discovery of the tar wastes in 1984. In 1991, the company recorded estimated future expenditures of $1.4 million for groundwater monitoring, construction of an interim groundwater treatment facility and design of site remediation. In addition, the company expensed an additional $200,000 in 1992 to cover the estimated cost to remediate 1,200 tons of waste presently in a storage pile. The company is pursuing recov- ery of response costs from KCPL. The Federal District Court ruled in the third quarter of 1993 that KCPL is liable to the company regard- ing the response costs at the Mason City site. (KCPL is a strong A rated company with total assets in excess of $2 billion.) Additional court proceedings will be held in 1994 or 1995 to determine the extent of that liability. In the opinion of the company, presently accrued liabilities of $800,000 are adequate to cover the company's share of future expenses at this site.
The company formerly operated a manufactured gas plant in Rochester, Minnesota. This facility was sold to another utility, which later demolished the plant. The site is currently owned by a utility and the City of Rochester. The limits of contaminated soil have been identified and are estimated to be 50,000 tons. Tentative agreements have been reached between the Minnesota PCA and all three parties noted above regarding the clean-up process. The remediation process will begin in early 1994. The total costs to clean-up this site are estimated to be $7.8 million. A verbal agreement has been reached among the parties regarding cost sharing and a written agreement is expected in the near future. The company has agreed to pay for $4.9 million of the estimated costs ($3.5 million was recorded in 1993, $1.2 million in 1992, $200,000 in 1991). To-date, all costs have been charged to expense.
The company owned and operated a manufactured gas facility in Albert Lea, Minnesota and is solely responsible for the site. Testing for contaminated soil and groundwater has taken place and additional testing will take place in 1994. Based on the past testing, contami- nation is at a low level. All costs have been charged to expense. $80,000 was spent in 1993 and $243,000 has been spent to-date. Estimated investigative and remedial expenditures in the amount of $400,000 were expensed in 1991. The company anticipates that a risk assessment will be completed by late 1994. Remediation requirements will not be known until the risk assessment is completed.
The company owned and operated a manufactured gas plant at Clinton, Iowa. The company believes that the coal gasification waste was removed subsequent to plant decommissioning, and therefore it is not necessary to accrue for any future liability. If hazardous wastes are found at the site, the EPA may name several potentially responsible parties in addition to the company, as other industrial operations have been conducted on or adjacent to the site. In September 1992, the company prepared a consent order (the agreement to investigate and, if necessary, remediate the site) and forwarded it to the Iowa Department of Natural Resources - Department of Environmental Quali- ty. On November 24, 1993, the company was notified that the site was referred to the Federal EPA.
In addition, the company has identified four other sites in the Midwest for which the company is potentially responsible. The company has not conducted an investigation of these sites, nor has the EPA requested that any investigations be initiated. No environmental response costs have been recorded for these sites, as no evidence has been brought forth to indicate that any of these sites contain hazardous materials. In January 1994, the company was notified by an Illinois property owner of a site which contains hazardous materials which may have come from a manufactured gas plant. Investigations are underway to determine if the company has any responsibility for the site.
The company has retained an outside law firm to pursue recovery from insurance carriers of environmental remediation costs applicable to the coal gasification sites. While the company's insurance carriers have stated that they are not liable, the company contends that it has coverage. Neither the company nor its legal counsel is able to predict the amount or timing of any insurance recovery, and accord- ingly, no potential recovery has been recorded.
Previous actions by Iowa, Minnesota and Illinois regulators have permitted utilities to recover prudently incurred remediation and legal costs. The company anticipates that any unreimbursed costs applicable to the Iowa, Illinois and Albert Lea, Minnesota jurisdic- tions should be recovered from gas customers. It is uncertain whether the company will recover any uninsured costs applicable to the Rochester, Minnesota site, as the company no longer serves that city, and no Minnesota precedent has been established for recovery in a similar situation.
Under the Federal Comprehensive Environmental Response, Compensation and Liability Act, a past waste generator can be designated by the EPA as a Potentially Responsible Party (PRP). Certain types of used transformer oil (primarily those containing polychlorinated bipheny- ls, or "PCBs") have been designated as hazardous substances by the EPA. The company has been cited as a PRP by the EPA in 3 instances which involve used transformer oil.
The company was identified in 1986 by the EPA as a PRP for the clean-up of the facilities formerly operated by Martha C. Rose Chemicals, Inc. (Rose) in Holden, Missouri. Rose, pursuant to permits issued by the EPA, was engaged in decontamination of PCB fluids and processing of PCB-contaminated electrical equipment for disposal including equipment sent to them by the company. Rose ceased opera- tions in 1986, was declared bankrupt, and did not comply with EPA orders for site clean-up. Final clean-up activities at the site will not begin until 1994. The Martha Rose Chemical Steering Committee has estimated that total clean-up cost may be up to $18 million. The company, along with 14 other steering committee members, has filed suit against non-participating potentially liable entities to recover their ratable share of the costs. The company has paid clean-up costs of $317,000 to-date. The Steering Committee has indicated that it has adequate funds for clean-up, and the company anticipates that addi- tional assessments, if any, will not be material.
In 1988, the EPA designated the company a PRP for the clean-up of former salvage facilities operated by B&B Salvage in Warrensburg, Missouri. The EPA pursued recovery of costs from several PRPs, although not from the company. The PRPs sued by the EPA in turn named the company as a Third Party Defendant in an attempt to recover a ratable share of the costs. In April 1993, the company paid $69,000 in full settlement of its liability for the claims asserted in that litigation.
In 1988, the EPA designated the company a PRP for the clean-up of former salvage facilities operated by the Missouri Electric Works, Inc. (MEW) in Cape Girardeau, Missouri. A portion of the PCB-contami- nated equipment found at the site was formerly owned by the company. The company notified the EPA that it disclaims responsibility for the site, as the equipment was in proper operating condition when sold by the company to a third party, which subsequently made arrangements to transport this equipment to MEW. The EPA has not responded to the company's disclaimer. The company has not recorded any liability for the MEW site, and management believes that it will be able to suc- cessfully defend itself against any claims applicable to the site.
(Employees)
The company has 979 regular employees consisting of 941 full-time and 38 part-time employees.
(Accounting Matters)
The company adopted Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes" in 1993. The new standard requires a deferred tax asset or liability to be recognized for each temporary book/tax difference, including timing differences flowed through and items not previously considered timing differences (primarily Deferred Investment Tax credits and Equity AFUDC). Corresponding regulatory assets or liabilities, reflecting the expected future rate treatment, have also been recognized. For this reason, the new standard did not have a significant effect on the income statement, but did result in increased regulatory assets and deferred tax liabilities. The balance sheet as of December 31, 1993 includes additional regulatory assets and deferred tax liabilities of $27.0 million as a result of the adoption of SFAS 109.
The company adopted SFAS No. 106, "Accounting for Postretirement Benefits Other Than Pensions" in 1993. Under the provisions of SFAS 106, the estimated future cost of providing these postretirement benefits is accrued during the employees' service periods. The postretirement benefit obligation at January 1, 1993 (transition obligation) was $30.9 million and is being amortized over a 20 year perod. The annual SFAS 106 cost for 1993 is $4.9 million, compared to the 1993 pay-as-you-go amount of $1.7 million. The company is deferring the difference between the SFAS 106 costs and the pay-as- you-go amount until rate cases are filed to recover the additional costs. Effective May 1993, the IUB allowed the company to recover $300,000 annually of additional SFAS 106 expense in gas rates. Effective November 1993, the IUB allowed recovery of $1.6 million annually of additional SFAS 106 expense in electric rates, subject to refund upon final determination. On the basis of generic hearings or specific rate orders issued to other utilities by the Minnesota Public Commission (MPUC), FERC and the Illinois Commerce Commission (ICC), the company believes that amounts deferred meet the criteria for deferral established by the Financial Accounting Standards Board. As of December 31, 1993 $2.6 million of SFAS 106 costs in excess of the pay-as-you-go amount have been deferred.
