VI ------- SECTION 1 INTRODUCTION The U.S. Environmental Protection Agency (EPA) began efforts in 1989 to create a data base containing the necessary data elements on utility combustion sources to support a market based system of acid rain controls. The EPA chose the 1985 National Utility Reference File (NURF) data, augmented by the U.S. Department of Energy's (DOE) Energy Information Administration (EIA) data, as the starting point for the development of the National Allowance Data Base (NADB). The NURF is a comprehensive utility-related data file that was developed in response to the National Acid Precipitation Assessment Program (NAPAP). (NAPAP, through many of the activities of its Emissions and Controls Task Group, has sponsored work both in developing estimates of current emissions from the utility industry and in projecting future emissions.) While the NURF did not meet all conceivable NAPAP needs for data on the utility industry, it provided a framework within which additional data could be conveniently developed. The NADB differs from the NURF file in the following ways: • The source of most data elements in the NURF was the NAPAP Emissions Inventory (Version 2), whereas the source of the data in the NADB was most often the EIA. • In preparing the NADB, the NURF data were extensively reviewed and data inconsistencies were eliminated through contact with State and local air agencies and utilities. • Data elements needed for calculation of allowances under Title IV of the Clean Air Act (CAA) were expanded in the NADB. Additional data for determining allowances under specific provisions of Title IV are included in the Supplemental Data File (SDF). The NADB Version 2.11 (NADBV211) data underwent several stages of careful review: by the EPA regions in summer 1990, prior to the release of Version 1.0; by EPA, during fall 1990 and spring 1991, which was followed by the release of Version 2.0 (Pechan, 1991); by the utilities, during a 45-day public review during summer 1991, which resulted in Version 2.1 (Pechan, 1992); and again by the utilities during a 60-day public review during summer 1992, 1 ------- culminating in the release of Version 2.11 (Pechan, 1993). The NADBV211 was used in 1993 to calculate sulfur dioxide (SO2) emissions allowances, as provided by Title IV of the CAA (PL, 1990). The NADB Version 2.2 (NADBV22) is an update to the NADBV211, necessitated by the CAA Title IV requirement that the SO2 allowances be reallocated for 1998. The data base structure (number and type of data elements) are identical in both files, as are the number of records. The new data base, NADB V22, is a result of identification variable changes (such as operating utility name and code, boiler ID, and ORIS plant ID and plant name) as well as changes to a few data elements for a small number of boilers due to EPA errors, court decisions, and litigation settlements. This document provides a description of how the NADB was developed and what its key data elements are. Those interested primarily in understanding how the data were assembled should read Section 2, which describes the development of the NADB. Specific information about each of the data elements is contained in Section 3. Section 4 includes material pertaining to the SDF. The appendices provide further details. ------- SECTION 2 NATIONAL ALLOWANCE DATA BASE The NADB contains data for utility units, namely "fossil-fuel-fired combustion devices," as defined in §402 of the CAA. The NADB does not necessarily encompass all affected units, and all units in the NADB are not necessarily affected units. Delineation of categories of units and their inclusion status in the NADB follows. • Utility units are included in the data base. These are generally boilers attached to generating turbines (generators) which are owned or operated by an electric utility; this includes existing units (on-line prior to November 15, 1990), new units (on-line after November 15, 1990), and planned units (not on-line as of December 31, 1991). • Existing, new, and planned combined cycle units are included. • New and planned simple combustion turbine units are included. • New cogenerators are not included unless the nameplate capacity is greater than 25 MW and they can potentially sell more than one-third of their generation to a utility. • New utility units that failed to submit Form EIA-860 by December 31, 1991 are not included. • Existing simple combustion turbine units (on-line prior to November 15, 1990) are not included. • Qualifying facilities (QF) under the Public Utilities Regulatory Policy Act (PURPA) are not included. The origin of the NADB is the 1985 NURF. Data were gathered from the sources listed below: • The 1985 National Emissions Data System (NEDS) submittals, which serve as the basis for the 1985 NAPAP Emissions Inventory. Form EIA-767 (EIA, 1982-1989) and Form FPC-67 (FPC, 1980-1981). Form EIA-759 (EIA, 1980-1989). ------- • The Federal Energy Regulatory Commission (FERC) Form FERC-423 (FERC, 1985-1989). • The EIA Integrated Data Base System (IDBS), which consists of Form EIA-860 (EIA, 1989a) and Form EIA-861 (EIA, 1989b). For further information on the NURF, see the NURF documentation (EPA, 1989). In July 1990, the data for each plant were submitted to the 10 EPA regions for review of the following key elements: 1985 SO2 emissions and emission rate, 1985 total heat input, and 1985 SO2 emission limits and associated variables. See Appendix A for a list of the EPA regions and associated States. Responses from the regions and the utilities were compiled and acted upon through October 3, 1990. The result was the NADB Version 1.0, a file with 2,456 generating unit records and 36 variables (data elements). It was disseminated to the public, evoking further responses. Upon checking the revised data submittals, inconsistencies among specified variables were discerned. In order to verify these values and eliminate inconsistencies whenever possible, sources were contacted and asked to clarify and document these data values. EPA made a concerted effort to revise the data base and incorporate whatever documented information could be obtained. In addition, this version took into consideration the occurrences of multi-header units in which there was not a one-to-one correspondence between boilers and generators. This was addressed by including a data base record for each boiler- generator combination within a plant. See Appendix B for an explanation and example of how data for multi-header units within a plant are handled. The NADB Version 2.0, produced in June 1991, contained boiler-generator data on fossil-fuel steam generators of all sizes that were reported to be in operation by 1990, or planned to soon be operational, in the 48 contiguous States and the District of Columbia. Also included were reported data for simple combustion turbine and combined cycle units planned for construction through 1995. The file included 3,732 boiler-generator records and 36 fields (variables). EPA offered The NADB Version 2.0 for public review (FR, 1991) during a 45-day comment period commencing July 19, 1991. After the close of the comment period on September 3, 1991, the Data Change Forms and associated documentation submitted to the EPA docket were reviewed by EPA (and EIA when appropriate). Determinations were made regarding acceptance of suggested changes to the data base. EPA's responses to all the requested changes were submitted to the docket. Changes were made to the data base, resulting in the NADB Version 2.1 (Pechan, 1992). Reported data for simple combustion turbine and combined cycle units planned for construction through 2006 were also included in this data base. In order to determine which units would qualify for certain special provisions of Title IV, and to calculate allowances for those units, additional information was required beyond that contained in the NADB. EPA prepared a Supplemental Data File (SDF) in 1992 to meet these requirements. Also, in the course of finalizing the NADB Version 2.1, EIA identified a number of potentially affected units under the Acid Rain Program in their data files that were not included in NADB Version 2.0. These units were generally not owned by traditional utilities but possibly fit the definition of utility unit as ------- defined in Title IV. EPA created an Adjunct Data File (ADF) containing the same data fields as the NADB for these potentially affected sources. The NADB Version 2.1 was then subject to a limited public review (FR, 1992) during a 60-day comment period initiated by EPA as of July 7, 1992. Only three items were opened for comment: (1) EPA's policy on outage hours, (2) comments on the SDF, and (3) comments on the ADF. Subsequent to the September 8, 1992 close of the comment period, the documents submitted to the two EPA dockets were reviewed by EPA. (One docket addressed issues raised regarding the NADB Version 2.1, the other docket addressed issues raised in response to the Allowance Allocation Proposed Rule.) Determinations regarding requested data changes on that notice were based on the following policy: • Changes to outage hour fields were made to conform to the final policy contained in the Federal Register notice supporting the NADBV211. Necessary changes were made to the SDF in response to comments. Units contained in the ADF that, after public comment, EPA believed to be affected units under the Acid Rain program were added to the NADBV211 and documented information added to NADBV211. In addition, several comments contained requests to change data which was already subject to the review in 1991. EPA made the following decisions regarding such requests: • If the request was a reiteration of a previous request where EPA correctly resolved the issue, the request was denied. If the request was a reiteration of a previous request where EPA failed to correct the error or the attempt to correct the error was incorrectly implemented, the request was reviewed and, if appropriate, granted. If the request was for a new data change that could have been previously submitted, the request was denied. This policy fairly implemented the intent of Congress to allow a limited (through December 31, 1991) opportunity to correct data errors, and made sure that requests submitted within the timeframe were handled correctly. For further details, see the Comment Responses available from the EPA docket for public review (EPA, 1993). Following the completion and implementation of these changes to the data base, the Core Rules (including Acid Rain permitting, allowance trading, and monitoring requirements) were promulgated in January 1993, the Technical Document was updated in February 1993 (Pechan, 1993), and the NADBV211 was released in March 1993 along with the Final SO2 Allowance Allocation Regulations. Following the final allowance allocations rule, a number of utilities initiated litigation regarding their allowances and underlying data and a number of other utilities petitioned the Agency for data changes. After litigation regarding the meaning of utility capacity under section 405(c) of the Act was remanded to the Agency, EPA proposed to revise the utility capacity field (UCAPFSST) for three utilities affected by ------- the provisions. (FR, 1996) In addition, based on the existing policy for reviewing petitions requesting data changes (above), the Agency determined that data changes requested for three units were appropriate. (FR, 1996) Also, units eligible for allowance allocations under section 405(g)(4) of the Act were required to provide documentation to EPA no later than December 31, 1995 to confirm that the units had commenced construction prior to December 31, 1990 and had commenced commercial operation from January 1, 1993 through December 31, 1995. Based on the submittals, EPA changed the relevant data fields in the SDF andNADBV211. (FR, 1996) NADB Version 2.2 (NADBV22) incorporated these limited changes to NADBV211 and was released with the Proposed 1998 Reallocation of Allowances on January 7, 1998. (FR, 1998). No changes have been made to NADBV22 since its release. Represented in the NADBV22 are 328 operating utilities, 956 plants, 2,757 generators, and 2,913 boilers. There are 2,468 records of one-to-one boiler-generator correspondence and 1,548 multi-headered records. The NADBV22 includes 3,842 boiler-generator records and 38 fields. The data are sorted by State name, plant name, boiler ID, and generator ID and then assigned a unique sequence number. The NADBV22 is available in dBASE III Plus PC format, as well as on the IBM mainframe in Statistical Analysis System (SAS) format. ------- SECTION 3 DESCRIPTION OF DATA ELEMENTS The NADBV22 has the same exact structure as that for the NADBV211: there are 3,842 records and 38 data elements. These data elements are grouped into five categories. The first category ~ identification or fixed variables ~ includes variables numbered 1 through 11. The second category contains elements numbered 12 and 13, which relate to the calculation of the 1985 actual SO2 emission rate, and the third category includes data elements numbered 14 through 18, which are associated with the determination of the 1985 allowable SO2 emission rate. Elements numbered 19 through 34 fall into the fourth category as EIA-supplied data. The fifth and last category includes the variables numbered 35 through 38, which are each calculated from other elements in the data base. Five tables, at the end of this section, further characterize the data: Table 1 lists and summarizes the variables; Table 2 offers a snapshot of the file with some sample data; and Tables 3, 4, and 5 detail State, regional, and operating utility summaries of selected variables. Because EPA has not updated all operating utility information, the operating utility summarizes do not reflect recent utility industry restructuring. The PC version file structure is found in Appendix C. Descriptions of each of the data elements appear below. Original sources of the data elements are listed when appropriate. However, for a given record, the actual NADBV22 data may have been obtained from a different source as a result of the utility responses submitted during the comment periods or because of a unique plant configuration or reporting method. IDENTIFICATION OR FIXED VARIABLES 1. Boiler-generator Sequence Number (SEQ) ~ The boiler-generator records in this data file, NADBV22, have the unique identifier, SEQ, that has the same value as that in the NADBV211 SEQ. This value was obtained after the NADBV211 data were sorted by State name, plant name, boiler ID, and generator ID, and was assigned a unique sequential number from 1 to 3,842. The NADBV22 is still sorted by SEQ, although some plant names and boiler IDs, among other data elements, were updated. 2. State Name (STATNAM) ~ This field, from Form EIA-860, contains the name of the State where the plant is located. 3. Plant Name (PNAME) ~ The name associated with each plant, as reported on Form EIA-860, is contained in this field. PNAMEs for planned units with identical names ("NA") but different plant codes (ORISPL) were modified by appending the ORISPL in order to uniquely identify the plants. ------- 4. Boiler Identification Code (BLRID) - This field identifies the boiler (in the fossil-fuel steam unit case) or gas- or oil-burning turbine (in the new simple combustion turbine case). In the majority of cases, there is a one-to-one correspondence with the generator ID. The source of the boiler identification code was Form EIA-767 or a report from the utility (if there was no Form EIA-767 filled out). If small, planned, or other units did not have an assigned boiler code, a default value of two asterisks followed by the GENID was used. 5. Generator Identification Code (GENID) - This field identifies the electrical generation unit (generator). In the majority of cases, there is a one-to-one correspondence with the boiler identification code. The source of the generator identification code was Form EIA-860. 6. Operating Utility Name (UTILNAME) - The source of the data was Form EIA-861. This name will be different from that in the 1985 NURF if the name or operator changed between 1985 and 1989. For the eight utilities with duplicate names, the State postal code was appended to the utility name to ensure uniqueness. 7. Operating Utility Code (UCODE) - Each operating utility has a unique utility code, originating from Form EIA-861. This field, associated with UTILNAME, also reflects 1989 status. 8 EPA Region (EPARGN) ~ This field contains the number of the EPA region in which the plant is located. See Appendix A for a complete list of regions and associated states. 9. County Name (CNTYNAME) ~ The county name was obtained from Form EIA-860. For planned units whose exact location was unknown, the CNTYNAME is "NOT IN FILE." 10 DOE (ORIS) Plant Code (ORISPL) ~ This plant code was originally developed by ORIS, which is a part of the Federal Power Commission. It is now used as a unique plant identification code assigned by EIA. 11. Total Phase 1 Allowances (TOTALPH1) ~ This field contains the total basic Phase 1 allowances, in tons, for units that appear in Table A of the CAA (with multi-header situations taken into account). The allowances in Table A, originally on the generator-level, were reallocated to the boiler-level and then adjusted for certain units that receive additional allowances under §404(a)(3) and §404(h) of the CAA. These total values are equal to the sum of Column A and Column B published in Table 1 of §73.10(a) in the Federal Register (FR, 1993). Therefore, these total values do not reflect subsequent deductions of allowances required under §416 to create the "auction and sales" allowance reserve that are published in Table 1, Column B. 1985 ACTUAL SO, EMISSION RATE-RELATED VARIABLES ------- 12. 1985 Boiler Total Heat Input (TOTHT) - Total heat input, in 1012 Btu, is the sum of the products of the amount of each fuel consumed and the associated heat content. These data, from the 1985 NURF, reflect 1985 values only. See Appendix D for detailed calculations. 13. 1985 Boiler SO2 Emissions (SO2) - This field contains SO2 emissions, in tons, from the 1985 NURF. See Appendix D for detailed calculations. 1985 ALLOWABLE SO2 EMISSION RATE (LIMIT)-RELATED VARIABLES 14. Boiler SO2 Regulatory Category (SO2CATEG) - The regulatory category determines the type of emission regulation the unit must meet. The plant may be regulated under one of the following: The State Implementation Plan (SIP), meaning that State or local regulations are binding (=1); The New Source Performance Standards (NSPS), 40 CFR, Part 60, Subpart D (=2); The revised NSPS (RNSPS), 40 CFR, Part 60, Subpart Da (=3); The NSPS, 40 CFR, Part 60, Subpart GG (=4); • The SIP for the existing gas turbine, combined cycle with auxiliary firing (=6); or The NSPS, 40 CFR, Part 60, Subpart GG for the existing gas turbine, combined cycle, with auxiliary firing (=9). For units with no information, SO2CATEG=0. The source of these data was EPA's Office of Air Quality Planning and Standards (OAQPS) preliminary SIP limit data base. These data were updated based on information and documentation provided by utilities, as well as Federal, State, and local regulatory agencies. See Appendix E for further information. 15. Boiler SO2 Scrubber Flag (SCRUBBER) - This field indicates whether the boiler was scrubbed (=1) or unscrubbed (=0). Scrubber information was obtained from EIA (EIA, 1985) and updated. Information is provided for planned units to the extent available. For planned units for which no information was available, SCRUBBER=9. Units that showed a zero percent SO2 removal efficiency were assumed to be unscrubbed. ------- 16. 1985 Boiler SO2 Emission Limit (FELIM85) - This field is the federally enforceable SO2 emission limit (rounded to four decimal places) that applied to each boiler in 1985, and converted to pounds of SO2 per million Btu of heat input (Ibs/MMBtu), if necessary. For units with more than one limit, the most stringent federally enforceable limit was used. For newer units subject to NSPS, and those that came on-line after 1985, the federally permitted limit was used. For units with no federally enforceable limit or units not yet permitted, a code of 99.9 was used. The source of these data was the OAQPS preliminary SIP limit data base. These data were updated based on information and documentation provided by utilities, as well as Federal, State, and local regulatory agencies. See Appendix E for additional details and conversion factors. 17. 1985 SO2 Emission Limit Annualization Factor (ANNFACT) - This field is the actualization factor that, when multiplied by the SO2 emissions limit (FELIM85), produced the annualized SO2 emission limit (ANNLIM85). See Appendix F for information on methodology. 18. 1985 SO2 Emission Limit Averaging Period (AVGPD) - This field contains 1 of 17 codes indicating the averaging period or time over which the emission limit, FELIM85, was applied. The source of these data was the OAQPS preliminary SIP limit data base. These data were updated based on information and documentation provided by utilities, as well as Federal, State, and local regulatory agencies. See Appendix E for further information. EIA-SUPPLIED VARIABLES 19. 1989 Generator Nameplate Capacity (NAMEPCAP) - This field contains the 1989 nameplate capacity of the existing (or planned) generator, in MW and rounded to two decimal places. Form EIA-860 generally was the source of this value. If the nameplate rating was expressed in kilovolt-amperes (kVA), the translation to MW was made by using the formula: MW = kVA * power factor/103 where kVA and power factor are specified by the manufacturer and stamped on the physical nameplate attached to the generator. For combined cycle units with auxiliary firing, the gas turbine MW and steam generating unit MW were combined for the nameplate capacity value. For planned units, the NAMEPCAP value represents the planned nameplate capacity as reported on Form EIA-860. 10 ------- 20. 1989 Generator Summer Net Dependable Capability (SUMNDCAP) - This field contains the 1989 summer net dependable capability of the existing generator, in MW and rounded to two decimal places. The source of this data element was Form EIA-860. For combined cycle units with auxiliary firing, the gas turbine MW and steam generating MW were combined for the summer net dependable capability value. For planned units, the SUMNDCAP value represents the planned summer net dependable capability as reported on Form EIA-860. Units built to produce both electricity and steam for sale may have more steam (boiler) capability than electric (generator) capability. For the generating units that have significant extra boiler capacity and sell steam, individual multipliers were developed to adjust boiler capability in terms of generator summer capability (kilowatts-electric). If a value was not available, the default value is NAMEPCAP. For units coming on-line after 1990, which may not have established a reliable value for summer net dependable capability, the capability was determined from the following formula: SUMNDCAP =NAMEPCAP * factor, where factor varies (EIA, 1990a) based on the type of unit as described below: Unit Type Factor Combined Cycle .85 Combustion Turbine .85 Steam Turbine .94 Jet Engine .87 Internal Combustion .97 21. Generator Month On-line (GENMNONL) ~ This data value, from Form EIA-860, is the month portion of the generator startup date. For existing units, this was the first electricity date (viz, the date when the unit began to produce electricity, including electricity generated during a testing period). For units that repowered, it was the repowered generator first electricity date. For planned units, it was the projected first electricity date at the time of NADBV211 development. 22. Generator Year On-line (GENYRONL) ~ This data value, from Form EIA-860, is the year portion of the generator on-line date. See GENMNONL for further details. 11 ------- 23. Boiler Month On-line (BLRMNONL) - Although the term "commenced commercial operation" is defined as having "begun to generate electricity for sale, including the sale of test generation" (FR, 1993), the generation of electricity occurs at the generator, thus potentially creating difficulty in determining the boiler on-line date that is used to categorize affected units for Phase 2 allowance allocations. Therefore, the following guidelines were complied with to determine boiler on-line dates: The boiler on-line month is the month portion of the boiler on-line date. For units from plants of at least 100 MW and with a generator first electricity on-line date between 1984 and 1989, the boiler on-line date is the generator first positive generation date (viz, the date when both the boiler first consumes fuel and the associated generator first produces generation). For units with a generator first electricity on-line date prior to 1984 or from plants with less than 100 MW, the boiler on-line date is the generator first electricity date. For units with on-line dates of 1990 and beyond, the boiler on-line date is the projected generator first electricity date at the time of NADBV211 development. If the boiler on-line dates are different for multiple boilers that are feeding one generator, the earliest of the boiler on-line dates is used for all the boilers feeding that generator, unless the boiler was new or replaced. If the boiler is new or was replaced, the date of the boiler's first consumption of fuel, or the date of commercial operation of the new boiler, as reported to EIA, was used. These data have been updated since NADBV211 publication when necessary for correct allocation of allowances. 24 Boiler Year On-line (BLRYRONL) ~ The boiler on-line year is the year portion of the boiler on-line date. See BLRMNONL for further details. 25. 1985-1987 Boiler-generator Average Total Heat Input, "Baseline" (BASE8587) ~ The average total heat input (also called "baseline"), in 1012 Btu, is the arithmetic mean of the calculated heat inputs for all 1985 through 1987 Form EIA-767 reported fuels. The heat input for each year was calculated in the same way as the 1985 total heat input, as shown in Appendix D. For steam units with no 1985 Form EIA-767 data (in plants under 100 MW), data were obtained elsewhere. The 1985 fuel use data were apportioned, based on MW, from Form EIA-759 plant- level data. The associated 1985 heat content was determined from the average of the 1986 and 1987 Form EIA-767 heat contents. If no heat content was reported on Form EIA-767 for either 1986 or 1987, the appropriate average State heat content (computed for each fuel reported by all plants in that State on Form EIA-767 from 1985 through 1987) was used as the default value. 12 ------- For units with OUTAGEHR=26,280 (the entire 1985 to 1987 baseline time period), the value for BASE8587 was an alternative representative baseline value assigned by EPA to correspond to 1 hour of fuel usage, as authorized by §402(4)(a) of the CAA. In this case, the value for OUTAGEHR was correspondingly changed to 26,279 (to avoid division by zero when calculating the adjusted baseline used for the allowance calculations). For multi-header units, there is a unique value for each boiler-generator, obtained by apportioning the boiler based Form EIA-767 fuel data to each generator, depending upon its fractional share of the total generation (or, if that is not reported, the nameplate capacity) associated with the boiler. When Form EIA-759 plant-level data were used, the data were first apportioned to each generator, depending upon its fractional share of the plant's fossil-fuel nameplate capacity. If there are multiple boilers feeding one generator, the data were divided equally among all the boilers connected to the multi-headered generator. For combined cycle units with auxiliary firing, all fuel consumed (including fuel from auxiliary boilers, duct heat, or scrubber reheat) was included. For gas turbines, fuel data were obtained from Form EIA-759 whenever possible. Otherwise, the information was obtained from the utilities. If there was no fuel consumption for all 3 years, the baseline value is 0. Note that outage hours do not affect the numerical value contained in this field. This baseline value is therefore not adjusted for either outage hours or for units that came on-line during the 1985 to 1987 time period. 13 ------- 26. Consecutive Planned and Forced Outage Hours (OUTAGEHR) - This field represents the number of continuous hours a unit was out of service between 1985 and 1987 due to a planned or forced outage for non-routine maintenance or for specified outage classifications accepted by EPA. The majority of the data were obtained from the Generating Availability Data System (GADS) (NERC, 1990) that is maintained by the North American Electric Reliability Council (NERC). NERC defines a planned outage as "the removal of a unit from service to perform work on specific components that is scheduled well in advance and has a predetermined duration (e.g., annual overhaul, inspections, testing)." It defines a forced outage as "an unplanned component failure (immediate, delayed, postponed, startup failure) or other condition that requires the unit be removed from service immediately or before the next weekend." For utilities that did not report to GADS, unit outages were allocated if they were well-documented planned or forced outages for non-routine maintenance reported to EIA. The following list contains the outage classifications that were accepted by EPA. ! Forced/planned non-routine maintenance and accidents, longer than or equal to 4 months. ! Outages of 3 months or longer caused by accidents (natural phenomena or incidents unrelated to the operation of the unit that are unpreventable, unforeseeable, and not caused by worker error). ! Discontinuous but related outages for forced/planned non-routine maintenance, where total duration was 4 months or longer. ! Discontinuous but related outages for accidents, where total duration was 3 months or longer. ! Outages of 4 months or longer, which were not caused by forced/ planned non-routine maintenance or accidents, in which the unit's emission rate was less than 1.2 Ibs/MMBtu and the allowance impact by not providing allowances to the operating utility was severe. If there were individual unrelated outages each totaling less than 4 months (2,920 hours) during the period from 1985 to 1987, the value of OUTAGEHR is 0. 27 Primary Fuel Indicator (PRIMFUEL) - This field, for those units with fuel use, has a value of 1 if the coal heat input was greater than 50 percent of the total heat input for the years 1985 through 1987, and a value of 2 otherwise (for oil/gas units). For those units which did not report any fuel use on Form EIA-767 for those years (generally, if the steam unit was on standby or out of service, if the unit was part of a plant under 10 MW in size, or if it is not a steam plant), the Form EIA-860 generator primary fuel variable was used to determine the value of PRIMFUEL (the value was set at 1 if the primary fuel was reported as coal, and was set at 2 otherwise). 14 ------- 28. 1980-1989 Gas Share (GAS8089) - This value, calculated from 1980 through 1989 Form EIA-767 data for oil/gas units on-line during the period from 1985 to 1987, is the percentage of gas consumed by each boiler during this time period. The equation used was: GAS8089=100*(1980-1989 gas heat input),'(1980-1989 total heat input). For units in plants under 100 MW which did not report fuel use prior to 1986, Form EIA-767 data from the 1986 to 1989 time period were used. This field was calculated at the boiler level from Form EIA-767 data for boilers in plants that were identified, using Form EIA-759, as consuming more than 75 percent gas between 1980 and 1989. For those boilers in plants not so identified, plant-level data from Form EIA-759 were used. The value is 0 for coal units (those with a greater than 50 percent coal share) on-line during the period from 1985 to 1987. 29. 1989 Generator Heat Rate (HEATRATE) ~ The generator heat rate value, in Btu/kWh, is the net full load heat rate reported for each generator on Form EIA-860. To ensure that estimated heat rates fell within a reasonable range of 5,000 to 25,000, contacts were made to confirm values that were outside that range. The higher values outside the range were either revised downward or were left alone, since they were reported for very old and inefficient units. A default value for fossil-fuel steam units was used if values of 5,000 or less (mostly in retired or planned units) were reported, or if no data were available. This default value of 10,000 was based on typical heat rates for new fossil-fuel-fired units that range between 7,260 (efficiency of 47 percent) and 13,648 (efficiency of 25 percent) (EIA, 1990b). For planned simple combustion turbine and combined cycle units, heat rate defaults of 13,648 and 8,322, respectively, were used (EIA, 1990b). 30. 1985 Generator Generation (GENER) - Whenever possible, generator generation for 1985, in GWh, was obtained from Form EIA-767. Generator-level generation data were not available for units in plants under 100 MW and for units whose utilities did not report individual generator generation. In these cases, the data were apportioned, by MW, from Form EIA-759 plant-level data. For existing combined cycle units with auxiliary firing, the gas turbine generation and the steam generating unit generation were combined for the generator generation value. For units not operating in 1985, the generation value is 0. 31. Total Capacity of the Fossil-steam Units of the Operating Utility (UCAPFSST) ~ This field is the sum, in MW, to the nearest integer, of the Form EIA-860 reported 1989 nameplate capacity of all the fossil-fuel steam units operated by the operating utility of the particular unit in 1989. In a few cases, this value is 0 because all of the utility's units retired before 1989 or had not come on-line by 1989. In addition, if the operated capacity was less than 0.5 MW, this field value is 0. As a result of litigation, three utilities had this data element modified. 15 ------- 32. Maximum of the Average Heat Inputs for Any Combination of Three Consecutive Years from 1980-1989 (MXBS8089) - This heat input data element (also called "maximum baseline"), in 1012 Btu, is the maximum of the average heat inputs for every combination of 3 consecutive years reported on Form EIA-767 between 1980 and 1989. It was calculated similarly to BASE8587, but only for units subject to §405(i) of Title IV of the CAA; the value is 0 otherwise. 33. Representative Year SO2 Emission Rate (RY_ER) - The representative year SO2 emission rate, in Ibs/MMBtu and rounded to four decimal places, is nonzero only for those cases in which there is a positive baseline (either BASE8587 or MXBS8089) value, but no 1985 emission rate. This field was assigned the 1985 (or 1986 or 1987) SO2 emission rate calculated from EIA data. The EIA emission rate was calculated using Form EIA-767 fuel quantity and quality data, EPA's AP-42 emission factors (EPA, 1985), and the SO2 control efficiency. See Appendix D for the formula. If a unit had a positive baseline value, an SO2RTE value of 0, all EIA emission rates calculated to be 0, and was more than 90 percent gas for either the 1980 to 1989 (GAS8089>90) or the 1985 time period, then this field was assigned a default value of 0.0006, based on the AP-42 factor for natural gas. During the comment period, a utility may have requested use of an alternate year's rate; if such a rate was necessary for allowance calculations and was approved, it was included. 34. Municipally Operated Flag (FLAGMUNI) - If an operating utility is a municipal utility as of December 1989, this field has a value of 1, and 0 otherwise. The source of this data element was Form EIA-861. CALCULATED VARIABLES 35. 1985 Boiler SO2 Emission Rate (SO2RTE) - The actual SO2 emission rate, in Ibs/MMBtu and rounded to four decimal places, was calculated from the boiler SO2 emissions (tons) in 1985 and the boiler total heat input of fuels burned (1012 Btu) in 1985. See Appendix D for detailed calculations. The equation used was: SO2RTE=(2 *SO2)/(1000 *TOTHT). 36. 1985 Annualized Boiler SO2 Emission Limit (ANNLIM85) - The "allowable 1985 SO2 emission rate," in Ibs/MMBtu and rounded to four decimal places, is defined in the CAA as an annual equivalent SO2 emission limit. ANNLIM85 was calculated using the equation: ANNLM85=ANNFACT*FELM85. 16 ------- 37. Generator Heat Input at 60 Percent Capacity (HT60) ~ This field, in 1012 Btu, was calculated on an annual basis using the formula as shown, where 5,256 is a conversion factor (60 percent of 8,760 hrs/yr): HT60=(HEATRATE*SUMNDCAP *5256)/l O9. The net summer capability was used because the nameplate capacity for many units was not a good measure of the maximum MW a generator can produce. Most utility planners use a measure of dependable capacity such as net dependable summer capability. 38. Boiler-generator Share of Generator Heat Input at 60 Percent Capacity (HT60SHR) - This field, in 1012 Btu, was calculated from HT60 for multi-header units. For each generator with multiple boilers, based on BASE8587, HT60 was apportioned among the boilers. If the BASE8587 value for the multiple boilers are all 0, HT60 was shared equally among the boilers. If there is a single boiler associated with a generator, HT60SHR is equal to HT60. 17 ------- Table 1 NADBV22 Variable List Field Number Variable Name Description 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 SEQ Boiler-generator sequence number (same as in NADBV211) STATNAM State name PNAME Plant name BLRID Boiler identification code GENID Generator identification code UTILNAME Operating utility name UCODE Operating utility code EPARGN EPA region CNTYNAME County name ORISPL DOE ORIS plant code TOTALPH1 Total basic Phase 1 allowances (tons) TOTHT 1985 boiler total heat input (1012 Btu) from NURF SO2 1985 boiler SO2 emissions (tons) from NURF SO2CATEG Boiler SO2 regulatory category (0=no information, 1=SIP, 2=NSPS D, 3=NSPS Da, 4=NSPS GG, 6=SIP for existing gas turbine, combined cycle, with auxiliary firing, 9=NSPS GG for existing gas turbine, combined cycle with auxiliary firing) SCRUBBER Boiler SO2 scrubber flag (1 =yes, 0=no, 9=no information) FELIM85 1985 boiler SO2 emission limit (Ibs/MMBtu) ANNFACT 1985 SO2 emission limit annualization factor AVGPD 1985 SO2 emission limit averaging period NAMEPCAP 1989 existing and planned generator nameplate capacity (MW) SUMNDCAP 1989 generator summer net dependable capability (MW) GENMNONL Generator month on-line GENYRONL Generator year on-line BLRMNONL Boiler month on-line BLRYRONL Boiler year on-line BASE8587 1985-1987 boiler-generator average total heat input, "baseline" (1012Btu) OUTAGEHR Consecutive planned and forced outage time during 1985-1987 >= 2,920 hours (hours) PRIMFUEL Primary fuel indicator based on greatest fuel heat share during 1985-1987 (1=coal>50%, 2=oil/gas) GAS8089 1980-1989 gas share (%) HEATRATE 1989 generator full load heat rate (Btu/kWh) GENER 1985 generator generation (GWh) UCAPFSST Total capacity of the fossil-steam units of the operating utility (MW) MXBS8089 Maximum of the average heat inputs for any combination of three consecutive years from 1980-1989 for selected units (1012 Btu) RY_ER Representative year SO2 emission rate (Ibs/MMBtu) FLAGMUNI Municipally operated flag (1=yes, 0=no) SO2RTE 1985 boiler SO2 emission rate (Ibs/MMBtu) ANNLIM85 1985 annualized boiler SO2 emission limit (Ibs/MMBtu) HT60 Generator heat input at 60 percent capacity (1012 Btu) HT60SHR Boiler-generator share of generator heat input at 60 percent capacity (1012 Btu) 18 ------- Table 2 Sample NADBV22 Data SEQ 1281 1282 1283 1284 1285 1286 1287 1288 1289 1290 SEQ 1281 1282 1283 1284 1285 1286 1287 1288 1289 1290 SEQ 1281 1282 1283 1284 1285 1286 1287 1288 1289 1290 SEQ 1281 1282 1283 1284 1285 1286 1287 1288 1289 1290 STATNAM KANSAS KANSAS KANSAS KANSAS KANSAS KANSAS KANSAS KANSAS KANSAS KANSAS CNTYNAME WYANDOTTE SEDGWICK SEDGWICK SEDGWICK CHEROKEE CHEROKEE CHEROKEE CHEROKEE CHEROKEE GRAHAM PNAME QUINDARO RIPLEY RIPLEY RIPLEY RIVERTON RIVERTON RIVERTON RIVERTON RIVERTON ROSS BEACH ORISPL 1295 1244 1244 1244 1239 1239 1239 1239 1239 1228 NAMEPCAP SUMNDCAP 157.50 23.00 31.30 33.00 10.00 12.50 37.50 50.00 25.00 11.50 135.00 26.90 30.40 34.50 11.00 9.00 38.10 53.20 31.50 12.00 128.96 0.00 0.00 0.00 0.00 0.00 177.81 286.59 3.41 0.04 661.00 961.00 961.00 961.00 344.00 344.00 344.00 344.00 344.00 62.00 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 BLRID 2 "1 "2 "3 LP LP 39 40 41 1 GENID ST2 1 2 3 3 4 7 UTILNAME KANSAS CITY CITY OF KANSAS GAS & ELECTRIC CO.

As was done with the NADB 2.1 Version, the SDF corresponding to the NADBV211 was available for public comment from July 7, 1992 to September 8, 1992 (FR, 1992). Following the same procedure as that for reviewing the NADB, the SDF-related documents submitted to the two EPA dockets were reviewed by EPA and the recommendations were implemented. The SDF for the NADBV22 (SDFV22) contains the same boiler-generator records that are in the NADBV211. It is linked to the NADB through the variable SEQ which is in both files. Including SEQ, there are 38 variables in the SDF, 30 of which are different from those in the NADB. The SDF was created so that sufficient information would be available to calculate all basic and bonus allowances. The data included in the SDF are used to classify each utility unit so that the appropriate provision(s) of the CAA can be applied to calculate Phase 2 allowances.

If data elements are at a plant level, all records for that plant will have those same data element values. In situations in which there are multi-header units (boiler(s) feeding multiple generators and/or generator(s) being fed by multiple boilers), the data handling was more complex. For data that are generator based, all plant records with the same generator ID will have the same value for those data elements. This holds true for boiler based data as well, so that plant records with the same boiler ID will have the same value for those data elements. Regardless of the type of boiler-generator correspondence, there are three variables whose value is specific to each record in the NADBV22. These are the sequence number, SEQ (field 1), the 1985 to 1987 baseline, BASE8587 (field 25), and the shared heat input, HT60SHR (field 38). The specific baseline value for each boiler-generator, for example, was obtained by apportioning the boiler based fuel data to each generator, depending upon its fractional share of the total generation (or, if that was not reported, the nameplate capacity) associated with that boiler. When Form EIA-759 plant-level data were apportioned to each generator, these data were divided equally among all of the boilers connected to a multi-headered generator. To illustrate this more concretely, consider a hypothetical plant in which boilers 1 and 2 feed generator 5, boiler 3 feeds generators 6 and 7, and boiler 4 feeds generator 8. The following five NADB boiler- generator records for this plant are illustrated in Table B-l. Table B-1 Hypothetical Multi-header Data SEQ PNAME BLRID GENID NAMEPCAP S02 BASE8587 9991 9992 9993 9994 9995 Test Test Test Test Test 1 2 3 3 4 5 5 6 7 8 75 75 24 100 25 111 222 333 333 55 11.111111 2.222222 33.333333 4.444444 .555555 B-l ------- The generator-related data (nameplate capacity, for example) would be the same for SEQs 9991 and 9992 because they have the same GENID, but it would be different for SEQs 9993 and 9994, since they have different GENIDs. Conversely, boiler-related data (such as SO2 emissions) would be the same for SEQs 9993 and 9994, but different for SEQs 9991 and 9992. The 1985 to 1987 baseline data would be specific to each of the five records. Multi-headered situations must be taken into account when aggregating data. In circumstances involving summing or averaging data, all the records may not have be included. Whether the data element was boiler or generator based will determine which set of unique records to include. The following two cases involving the hypothetical plant depicted above describe the aggregation of specified data: In order to compute the plant's total SO2 emissions ~ boiler based data ~ it would not be appropriate to sum the five records with SEQs 9991 through 9995, since the boiler-level data for BLRID=3 appears in both the SEQ=9993 and SEQ=9994 records. Thus, the SO2 data from the four records with SEQs 9991 through 9993 and 9995 would be totaled for the plant SO2 emissions. The other non- identification boiler based variables in addition to SO2 are TOTALPH1, TOTHT, SO2CATEG, SCRUBBER, FELIM85, ANNFACT, AVGPD, BLRMNONL, BLRYRONL, GAS8089, MXBS8089, RY_ER, SO2RTE, and ANNLIM85. To calculate the plant's total nameplate capacity (including planned units) ~ generator based data ~ it would not be correct to find the sum of either all of the plant's five records or the four boilers described above. This is because the capacity data for GENID=5 occurs in both SEQ=9991 and SEQ=9992, so the plant capacity would be determined by totaling the NAMEPCAP data for the four records with SEQs 9992 through 9995. The other non-identification generator based variables in addition to NAMEPCAP are: SUMNDCAP, GENMNONL, GENYRONL, HEATRATE, GENER, FLAGMUNI, and HT60.

However, both TOTHT and SO2 were most often calculated by utilities at the boiler level from quantities of fuel burned and fuel qualities such as heat and sulfur content. The equations that EPA utilized to calculate TOTHT and SO2, in addition to SO2RTE, are described below. MONTHLY TO YEARLY VALUES Frequently, the data for fuel use and heat content (or heating value) and sulfur content (or sulfur percent) were recorded on a monthly (or daily) basis. In order to calculate on a yearly basis, these data were converted to yearly data using the following method: For each fuel, the total amount of fuel used for the year was calculated by adding the monthly fuel used. • The yearly heat and sulfur contents for each fuel were determined on a fuel use weighted average. This weighted average was calculated by multiplying each month's fuel use and associated heat (or sulfur) content, and then adding these monthly values and dividing by the yearly fuel used. ACTUAL 1985 YEARLY TOTAL HEAT INPUT CALCULATION The equation used to calculate the yearly total heat input (TOTHT) is as follows: TOTHT = coal heat input + oil heat input + gas heat input (1) (in!012Btu) 1012 Each fuel type heat input was calculated on a yearly basis using the following equation: fuel heat = (fuel burned) * (wtd. av. heat content) * (conver. fact.) (2) (in Btu) For coal, fuel burned is usually in tons and heating value is usually in Btu/lbs. Thus, the conversion factor is 2000 Ibs/ton. D-l ------- For oil, fuel burned is usually in barrels and heating value is usually in Btu/gal. Thus, the conversion factor is 42 gal/bbl. For gas, fuel burned is usually in cf, and heating value is usually in Btu/cf Thus, the conversion factor is 1. ACTUAL 1985 YEARLY SO2 EMISSIONS CALCULATION The equation used to calculate the yearly SO2 emissions (SO2) is as follows: SO2 = (coal SO2 emissions) + (oil SO2 emissions) (3) (in tons) If gas is the only fuel, the SO2 gas emissions were assumed to be 0. Each fuel type SO2 emissions was calculated on a yearly basis, using the equation: fuel (fuel (yrly wtd. (AP-42 (1 - scrb. (units (4) SO2 emissions = use) * av. fuel * fact-) * effic- 0//0 * conver. (in tons) sulfur %) /100) fact.) For coal, the yearly fuel burned is in tons/yr and the AP-42 factor (which accounts for the ash retention of sulfur in coal), in Ibs SO2/ton coal, is by coal type: Coal Type AP-42 Factor bituminous, anthracite 39 Ibs/ton subbituminous 35 lignite 30 For oil, the yearly fuel burned is in gal/yr. If it is in bbl/yr, convert using 42 gal/bbl oil. The AP-42 factor (which accounts for the oil density), in Ibs SO2/thousand gal oil, is by oil type: Oil Type AP-42 Factor distillate (light) 142.6 lbs/1000 gal residual (heavy) 159.3 lbs/1000 gal For all fuel, the units conversion factor is 1 ton/2000 Ibs. ACTUAL 1985 YEARLY SO2 EMISSION RATE CALCULATION When the SO2 tons and heat input for all fuels was known, the equation for calculating the SO2 emission rate (SO2RTE) is as follows: SO2RTE = 2 * (total SO, emissions in tons) (5) (in Ibs/MMBtu) 1000 * (total heat input in 1012 Btu) If the emission rate was known only for coal (from continuous emissions monitoring, for example), yet oil was also burned, the following steps were taken to calculate the emissions rate for all the fuels: D-2 ------- Use the coal SO2 rate (in Ibs/MMBtu) and coal heat input (in 1012 Btu) to "back calculate" the coal SO2 emissions with the formula: coal SO2 emissions = 1000 * (SO^ coal em. rate) * (coal heat input) (6) (in tons) 2 Calculate the oil SO2 emissions using equation (4). Sum the coal and oil SO2 emissions using equation (3). Calculate the coal and oil heat inputs using equation (2) and sum them using equation (1). Calculate overall SO2 emission rate using equation (5). D-3 ------- D-4 ------- APPENDIX E ENFORCEABLE SO, EMISSION LIMIT DETERMINATIONS ------- ------- APPENDIX E ENFORCEABLE SO2 EMISSION LIMIT DETERMINATIONS The source of federally enforceable limits was the preliminary SIP limit data base developed by OAQPS. This data base (developed after a comprehensive review of all Federal, State, and local regulations affecting combustion boilers was conducted) provided Federal emission limit information for units in 1985, usually expressed in pounds of SO2 per million Btu. In certain cases, these limits were not expressed in Ibs/MMBtu and were converted using the factors shown in Table E-l. Limits were rounded to four decimal places. In addition to emission limits, the data base provided the averaging periods over which these limits were enforced. (These averaging periods were essential to EPA in its determination of annual allowable 1985 SO2 emission rates.) The 17 codes for the averaging period are listed in Table E-2. The data base also includes the SO2 regulatory category affecting each unit. For further information, see the documentation for the SIP database (SAIC, 1990). Following the development of this EPA SIP limit data base, the information was reviewed by the EPA regional offices and some State agencies and utilities. Cases where limits were still in question were followed up with telephone calls to resolve any conflicts in information received. The factor for converting pounds of sulfur to pounds of SO2 is based on the molecular weights of sulfur (32) and SO2 (64). Limits expressed as a percentage of sulfur or parts per million (ppm) depend on the energy content of the fuel and thus may vary, depending on several factors such as fuel heat content and atmospheric conditions. Generic conversions for these limits were based on the assumed average energy contents listed in Table E-l. In addition, limits in ppm vary with boiler operation (e.g., load and excess air); generic conversions for these limits assume, conservatively, very low excess air. The remaining factors were based on site-specific heat rates and capacities to develop conversions for Btu per hour. Standard conversion factors for residual oil are 42 gal/bbl and 7.88 Ibs/gal. A limit of 99.9 appears for units which had no federally enforceable limit in 1985 and/or no permitted limit (for new units). These were generally cases in which either the State never submitted the limits as part of its SIP and/or EPA never approved the limits; these units were therefore considered not to have a federally enforceable limit.

Capacity factor was based on 1985 utilization [=(1985 EIA total heat input in 1012 Btu)/ (HEATRATE*SUMNDCAP*8760/109)]. For post-1985 units, a capacity factor of 0.65 was assumed. The annualization factor for these cases was assumed to be 1.0.

Many emission limits are enforced on a shorter term basis (or averaging period) than annually. Because of the variability of sulfur in coal and, in some cases, scrubber performance, meeting a particular limit with an averaging period of less than a year and at a specified statutory emissions level would require a lower annual average SO2 emission rate (or annual equivalent SO2 limit) than would the shorter term statutory limit. EPA has selected a compliance level of one exceedance per 10 years. For example, an SO2 emission limit of 1.2 Ibs/MMBtu, enforced for a scrubbed unit over a 7-day averaging period, would result in an annualized SO2 emission limit of 1.16 Ibs/MMBtu. In general, the shorter the averaging period, the lower the annual equivalent would be. Thus, the annualization of limits was established by multiplying each federally enforceable limit by an annualization factor that is determined by the averaging period and whether unit the unit was scrubbed. The annualization factors developed by EPA (Radian, 1991) are listed in Table F-l. The development of these factors was based on accepted EPA statistical methods using a data base containing the utility units' continuous emissions monitoring (CEM) system results. This data base is a cross-sectional representation of utility plants with units of different sizes, with or without flue gas desulfurization (FGD) systems (or scrubbers), and different coals. Factors were developed using various averaging periods and two different compliance levels. For further information, see the annualization factors development report (Radian, 1991).

United States Code G-2 ------- SECTION 1 INTRODUCTION The Supplemental Data File (SDF) Version 2.2 was developed by the U.S. Environmental Protection Agency (EPA) as an extension of the National Allowance Data Base (NADB) Version 2.2 to provide data that were not included in the NADB that are needed to determine Phase 2 allowance allocations as specified by the Clean Air Act (CAA).1 For more information regarding the methods of calculating Phase 2 allowances, please refer to Technical Documentation for the 1998 Reallocation of Allowances, prepared for the U.S. Environmental Protection Agency by ICF Incorporated. While the NADB contains sufficient information to calculate Phase 2 allowance allocations for the vast majority of affected units, there are some provisions in the CAA that require data not contained in the NADB because they were typically only needed for a few units in order to determine eligibility or calculate sulfur dioxide (SO2) allowances. To ensure consistency and ease of overall calculations, the SDF is structured similarly to the NADB. Accordingly, each record (or unit) in the SDF corresponds exactly to a record in the NADB. The SDF contains several data elements from the NADB Version 2.2, referred to as "identification fields," which are included to ease the task of matching information for specific units from the two files. Like the NADB, the SDF also contains three other types of fields: data fields, calculated fields, and flag fields. This appendix is presented in four sections, the first of which is this Introduction. Section 2 describes the four different types of variables used in the SDF and includes a summary table showing content, source, and type for each SDF data item. It also includes a table showing the dBASE III Plus format file structure of the SDF. Section 3 describes each CAA provision that requires supplemental data for allowance calculations, the specific eligibility requirements for each of the applicable provisions, and the sources of the data. Section 4 presents sample data for all the fields in the SDF. Note that all interpretations in this document regarding definitions of statutory terms and provisions, unit eligibility, and the suitability of data sources were made by EPA and are consistent with the final acid rain rules.

G-3 ------- G-4 ------- SECTION 2 STRUCTURE OF THE SUPPLEMENTAL DATA FILE INTRODUCTION As noted in Section 1 of this appendix, the SDF is structured similarly to the NADB, with one record for each boiler-generator combination. The file contains 3,842 records and 38 fields (variables). Each record in the SDF corresponds exactly to a record in the NADB, facilitating the matching of data between the two files. This section describes the structure of the SDF in three ways. First, the four SDF variable types are described, and examples of each type are given. Second, an alphabetical list of variables is presented, including the field name, a brief description, the source of the data, and the variable type. Finally, the actual dBASE III Plus PC format file structure is listed. VARIABLE TYPES There are four types of data elements or variables included in the SDF — identification, data, calculated, and flag variables: ! Identification variables are fields from the NADB that are used to identify units in the SDF. These fields are mostly intended to ease the identification and selection of records during the allowance allocation calculations. Examples of identification variables are SEQ (boiler- generator sequence number) and PNAME (plant name). ! Data variables contain information collected by EPA's Energy Information Administration (EIA) and EPA from forms, reports, or other documentation. These also include variables that EIA calculated from data supplied by utilities on various forms. Examples include CMIN80 (1980 utility commercial/industrial sales in BkWh) and SPOP8088 (State population percentage increase, 1980 to 1988). ! Calculated variables contain information calculated from the values in other NADB and SDF fields, such as SMCOPCT (utility percent of capacity as small coal units). ! Flag variables are numeric fields with a width of 1 that hold one of two possible values. A value of 1 indicates "Yes" or "the unit/utility meets the condition," while a value of 0 indicates "No" or "the unit/utility does not meet the condition." For example, in the CONTUTIL field, a value of 1 indicates that the unit was owned by a utility that furnishes electricity, electric energy, steam, and natural gas within an area consisting of a city and one contiguous county as stipulated under §405(f)(2) of the CAA. A value of 0 indicates that the unit was not owned by such a utility. G-5 ------- LIST OF FIELDS IN SUPPLEMENTAL DATA FILE Table G-l shows a list of fields in the SDF, listed alphabetically by field name.

For each of the applicable provisions (or subsections in Title IV), the following information is provided: • A summary of the provision; A section listing and describing the supplemental data elements required (in addition to those elements already in the NADB), including the field name and the purpose of the field (i.e., whether the data element is needed to determine eligibility for the provision or to calculate allowances under the provision); • A table summarizing the data elements and the source of the data; and • The methods used to determine which units satisfy the eligibility criteria. In some cases, the number of potentially eligible units was narrowed down by taking each separate eligibility requirement for a given provision in turn, starting with the most easily identifiable requirements and moving to the more specific criteria as the number of potentially eligible units was reduced. This "winnowing" process, which was conducted in order to limit the amount of additional information required, is described more fully in each of these cases, where applicable. Note that each section of the CAA discussed in this appendix is presented on a new page for ease of reference.

G-25 ------- SECTION 405(i)(2) Provision Summary §405(i)(2): A unit subject to §405(b)(l), "(A) the lesser of whose actual or allowable 1980 emissions rate has declined by 50 percent or more as of the date of enactment of the Clean Air Act Amendments of 1990, (B) whose actual emissions rate is less than 1.2 Ibs/MMBtu as of January 1, 2000, (C) which commenced [commercial] operation after January 1, 1970, (D) which is owned by a utility company whose combined commercial and industrial kilowatt- hour sales have increased by more than 20 percent between calendar year 1980 and the date of enactment of the Clean Air Act Amendments of 1990, and (E) whose company-wide fossil-fuel sulfur dioxide emissions rate has declined 40 percent or more from 1980 to 1988," receives additional allowances equal to the difference between allowances calculated based on a baseline consisting of any 3 consecutive calendar years from 1980 to 1989 and allowances under §405(b)(l). Supplemental Data Elements Required \ 1980 SO2 Emission Rate ~ The boiler's annual average 1980 SO2 emission rate, calculated by EIA from Form FPC-67. ! 1980 SO2 Emission Limit ~ The unit's allowable federally enforceable emission rate in 1980. Electric utilities with eligible units supplied information documenting the applicable federally enforceable 1980 SO2 emission limitation regulations and/or permits for their units. This limit was not subject to annualization. ! SO2 Emission Rate as of Enactment ~ The boiler's SO2 rate as of enactment, which EPA has interpreted to mean the boiler's annual average SO2 emission rate in 1990. This information was calculated by EIA from Form EIA-767. ! SO2 Emission Limit as of Enactment ~ The unit's allowable federally enforceable emission rate as of enactment, which EPA has interpreted to mean the limit as of 1990. Electric utilities with eligible units supplied information documenting the applicable federally enforceable 1990 SO2 emission limitation regulations and/or permits for their units. This limit was not subject to annualization. ! 2000 Actual SO2 Emission Rate ~ The boiler's actual average SO2 emission rate for 2000. Based on comments on the Proposed 1998 J^allocation of Allowances (63 FR 0714, January 7, 1998), this field will reflect the unit's actual SO2 emission rate rom 1996 through 1999, whichever year the emission rate is below 1.2 Ib/mmBtu, as calculated from data submitted with the Emissions Tracking System. 1996 and 1997 data from potentially eligible units have been received and quality assured. For two of the potentially eligible units, the 1997 data were lower than 1.2 Ib/mmBtu and have been entered in to this field. However, until 1998 and 1999 data are received and quality assured for the other potentially eligible units, this value will be assumed to be less than 1.2 Ibs/MMBtu. G-26 ------- 1980 Utility Commercial/Industrial Sales ~ The utility's combined commercial and industrial sales in 1980, from Form EIA-412, Annual Report of Public Electric Utilities, U.S. Department of Energy, Energy Information Administration, 1980; and Form FERC-1, Annual Report of Major Electric Utilities, Licensees, and Others, Federal Energy Regulatory Commission, 1980. 1990 Utility Commercial/Industrial Sales ~ The utility's combined commercial and industrial sales in 1990, from Form EIA-861. 1980 Utility SO2 Emission Rate ~ The utility's average SO2 emission rate in 1980. The utility- level SO2 rates were calculated by EIA from Form FPC-67. 1988 Utility SO2 Emission Rate ~ The utility's average SO2 emission rate in 1988. The utility- level SO2 rates were calculated by EIA from Form EIA-767.

(2) Next, units must have come on-line after January 1, 1970. (3) Potentially eligible units must also be owned by a utility whose combined commercial and industrial sales (MWh) increased by more than 20 percent between 1980 and 1990; that is, the quotient Utility's 1990 Commercial and Industrial Sales Utility's 1980 Commercial and Industrial Sales must be greater than 1.2. (4) Units must also be owned by a utility whose SO2 rate decreased by 40 percent or more from 1980 to 1988; that is, the quotient Utility's 1988 SO2 Emission Rate Utility's 1980 SO2 Emission Rate must be less than or equal to 0.6. (5) If an eligible unit's 1980 SO2 emission rate was less than its 1980 emission limit, then its rate must have decreased by at least 50 percent from 1980 to 1990; that is, the quotient Unit's Actual 1990 SO2 Emission Rate Unit's Actual 1980 SO2 Emission Rate must be less than or equal to 0.5. G-28 ------- However, if the eligible unit's 1980 SO2 emission limit was less than its 1980 emission rate, then the unit's limit must have decreased by at least 50 percent from 1980 to 1990; that is, the quotient Unit's 1990 SO2 Emission Limit Unit's 1980 SO2 Emission Limit must be less than or equal to 0.5. (6) Finally, as of the year 2000, the units must have an actual SO2 emission rate that is less than 1.2 Ibs/MMBtu. As noted above, all units that satisfy conditions (1) through (5) were assumed by EPA to have a rate of less than 1.2 Ibs/MMBtu for the year 2000. G-29 ------- SPECIAL MULTI-HEADERS While not called for by any specific provision, there is one additional calculated field required to identify records with boilers that serve existing generators with nameplate capacity greater than 25 MW and also serve at least one generator with nameplate capacity less than or equal to 25 MW. The addition of this field is necessary to ensure that boilers are not "partially affected" in accordance with the final rule. To ensure that all boilers are either affected or unaffected, the flag variable SPECMULT was created and set equal to 1 for these special multi-header boilers, indicating that the specified boiler-generator combination is classified as an "affected" unit, and is therefore subject to the SO2 emission limit, as provided in Title IV §405. Supplemental Data Elements Required Data Element Special Multi-header Unit (Flag Field) Field Name SPECMULT Source Calculated G-30 ------- SECTION 4 EXAMPLES OF SDF DATA Table G-3 is a sample of SDF data. It shows the complete data for the first five records in the file. Data for each field or variable are labeled with the appropriate field name, with the first value in each row representing the boiler-generator sequence number, SEQ. To find the value for a given variable, for instance the Barry plant's boiler 5, generator 5 record, look at the appropriate SEQ value in the first column and follow that row to the appropriate variable. For example, to find the SPOP8088 value for the state in which the Barry 5,5 boiler-generator combination is located, find the SEQ value "5" in the first column of the third group of rows, and follow that row (shaded in the table) across until you reach the SPOP8088 column (also shaded). There the value "5.40" indicates a state population growth rate of 5.4 percent during the period from 1980 to 1988 for Barry's state, Alabama. Note that a value of 0 is entered in a number of fields for the records shown, indicating either that the true value of the variable is in fact 0, or that the unit and/or its operating utility was not eligible for the applicable provision (see text for a complete description of each data element and its eligibility requirements).
