INTRODUCTION

   This application form has been prepared by the Department of Environmental Regulation to guide utilities in the preparation of an application for power plant site certification and to aid affected state agencies, local governments, and interested persons in the review of an application. This form outlines the prescribed format for the submission of complete and sufficient applications.

   Prior to issuance of a Site Certification by the Governor and Cabinet, Department of Environmental Protection (DEP), Department of Community Affairs (DCA), Public Service Commission (PSC), Water Management Districts (WMD), and other affected agencies are required to assess the potential effects upon the environment, ecology and society by the proposed plant in order to insure that the construction and operation of the plant will be consistent with applicable environmental standards, and the public policy and legislative intent of the Power Plant Siting Act as set forth in Chapter 403, Part II, Florida Statutes.

   Terms used in this form shall have the same meaning set forth in Section 403.503, Florida Statutes, and Florida Administrative Code Rule 17-17.021.

PREPARATION OF THE APPLICATION

   The format of the application is intended to minimize the efforts of the applicant, the reviewing agencies, and others in the preparation and review of the application. The form may be periodically modified through the statutory rule revision procedures to further achieve these objectives.

   If the applicant asks to use a format other than that outlined in this instruction form, as allowed by Fla. Admin. Code Rule 17-17.051(l)(a), in order to match federal documentation requirements, each section must contain a reference as to which segment of the DEP format will be addressed therein. A master cross-reference sheet should be included as well.

   The information presented should discuss the conditions of the plant site, including associated facilities and electrical transmission corridors prior to construction, the anticipated changes to these conditions resulting from construction, and the anticipated effects of the project's operation and maintenance so as to provide reasonable assurance that applicable state, regional or local standards will be met.

   It is suggested that preparation of the application be coordinated with the DEP, DCA, PSC, appropriate water management district, the Game and Fresh Water Fish Commission, the Department of Natural Resources, and any federal agency that might be required to prepare an environmental impact statement.

   After filing of an optional Notice of Intent to file an application, an applicant may request a meeting with the DEP, statutory parties, and those agencies known to have jurisdictional matters affected, in order to review the applicant's plans and information requirements for the certification. The plans to be reviewed must be made available for review at 30 days before the meeting. The DEP will give notice of such meetings to all statutory parties, the public, and to any persons who have indicated a intention to become a party. No fewer than 14 days prior to the meeting, the DEP shall provide to the applicant a list of each person to whom such notice was given or mailed. The purpose of the meeting will be to determine the scope, quantity, and level of information to be included in the application to reach agreement on the methods to be used in providing such information, and to define the nature of supporting documents to be included in the application. As dictated by the nature of the applicant's proposed facility, the DEP, the applicant, and other affected agencies may agree in writing that certain portions of the information requirements will not be applicable to the applicant's submittal. It is not contemplated that all sections of this form need to be extensively discussed in all applications. In some instances "not applicable" or a general statement may be sufficient.

DATA REQUIREMENTS

   Information obtained from state, federal, local and regional governmental agencies, educational institutions and qualified consultants may be used when completing the application. All published documents used as supporting data must be referenced and if not publicly available, be made available for examination and copying upon request. If the applicant or his consultant gathers additional information regarding air and water quality, noise conditions, solid wastes or other environmental impacts, the methods shall be those duly adopted, published or otherwise approved by the DEP. Otherwise, data collection procedures should be discussed with the appropriate DEP staff to obtain mutual understanding and approval. The applicant may choose, for economic or other reasons, to submit a "worst case analysis" in lieu of any data required below. In such cases agency review will proceed on the worst case basis presented.

   Commonly available information and materials may be incorporated in the application by reference. The incorporated material shall be cited in the application and its content described briefly. The applicant shall indicate where the referenced material may be obtained. Upon a written request by any party, the applicant shall make available for inspection or copying any materials unavailable through other public sources.

   Concise descriptive or narrative text, as well as, tables, maps, charts, graphs, etc., should be used where possible. Data may be summarized to reflect maximums, minimums, and averages. However, each subject should be documented and treated in sufficient depth to permit the reviewer to readily evaluate the extent of the environmental impact. Line drawings, photographs, and architectural and engineering concepts should be used where they contribute to the clarity and brevity of the application. Cross-referencing is strongly recommended.

   Information should reflect observations and measurements which yield data sufficient in comprehensiveness and quality for the agencies to conduct their required studies in order to assess the impacts of the proposed electrical power plant. Data may be summarized by giving maximums, minimums and averages. In some instances this form indicates the specific environmental effects which are to be evaluated, especially during site preparation and plant construction; consequently, the parameters to be measured will be apparent. In some cases it may be necessary to establish a monitoring program to identify other potential or possible effects. It is strongly suggested that the applicant and the Department agree in writing to any monitoring or data gathering program prior to implementation. Sample station location, sampling frequency, methodology, (including calibration and checks with standards) and instrumentation for both collection and analysis should be thoroughly discussed. Information should be provided on instrument accuracy, sensitivity, and especially, the reliability of highly automated systems. Standard analytical or other techniques as used by DEP should be used or permission to vary the method should be obtained.

   Where information from published data has been used by the applicant, it should be concisely summarized and documented by reference to the original data sources. Where the availability of original sources that support conclusions is limited, provide either extensive quotations or reference to accessible secondary sources. In all cases, information derived from the applicant's field measurements should be clearly identified when used to verify the applicability of similar studies found in the literature.

   Any reports of work (e.g. ecological surveys) supported by the applicant that are of significant value in assessing the environmental impact of the facility should be included as appendices or supplements if requested. Any deviation from department standard procedures by the authors of the above mentioned reports should be well documented and discussed.

   Whenever new information is submitted in response to completeness or sufficiency remarks, or at the applicant's own volition, this shall be reflected in updates to the application which shows the old language and the new. As a suggestion, rule style format may be used: underline new text strike over deleted text. Or, if this proves too cumbersome, provide some indication of where language has been changed. In all cases, the newly submitted information must be in a format (e.g., paper size, quality, hole-punching) which can be readily inserted and collated into the original application.

DATA GATHERING AND MONITORING APPENDICES

   The chapters and sections in the following contain directions concerning data gathering procedures and the scope of monitoring to be performed before, during, and after plant construction and operation. It is not intended, however, that a separate monitoring discussion be included in the application at every point where this form alludes to monitoring. All technical descriptions of data gathering procedures and monitoring plans should be placed in an appendix. The text should contain appropriate cross-references to the appendix for the benefit of those agencies and individuals desiring to evaluate the adequacy of the monitoring and data gathering procedures.

   The monitoring appendix may consist of a plan of study or pre-application agreement which has been reviewed and approved by the Department before the application is submitted. This appendix should describe the data gathering and monitoring procedures used to establish the existing conditions at the proposed site, and any associated facility locations or corridors, as well as used to predict the impacts that are expected to result from project construction and operation.

   Construction monitoring proposals must be submitted as part of the original application filing, but shall not constitute the basis for a finding of insufficiency, and any changes to the originally proposed monitoring shall not constitute major amendments of the application. The program for the plant operational period may be submitted to the department no later than six months and preferably one year before the plant start-up target date (see chapter 5 introductory remarks).

STATE ACTION ON SUBMITTED APPLICATIONS

   The State's procedures for submitted applications are outlined in Sections 403.50l-5l9, Florida Statutes, the Department of Environmental Protection's companion rule Chapter 62-17, Part I, Florida Administrative Code, and the Public Service Commission's companion rule 25-22.80 - .84, Florida Administrative Code. It should be noted that certification in itself does not convey title or grant easements for any property, state-owned or otherwise. Therefore, where the applicant desires to use or cross state-owned lands, the appropriate government agencies should be contacted at the earliest possible date regarding the use of public properties. The department may certify a site for an ultimate mega wattage generating capacity to be obtained by incremental additions of generating units until ultimate buildout is reached. The conditions upon which such a certification may be issued will be made part of the certification.

   Cogenerators and Resource Recovery Facility (RRF) owners, where subject to the requirements of the Florida Electrical Power Plant Siting Act, should discuss the need for their facilities in three major areas, unless this information has previously been presented to the PSC: (1) internal benefits to the cogenerators or RRF owners such as access to lower cost electricity, energy savings, use of excess steam, energy efficiency, or revenues generated by lower cost products; (2) benefits to the county, region, and state, such as oil replacement, conservation of land or water, or protection of water quality; and (3) an assessment of the impact of the proposed facility on the reliability, generation planning, unit dispatching and generation costs of the power-purchasing utility, as coordinated with the affected utilities.

 

CHAPTER 2

SITE AND VICINITY CHARACTERIZATION

   This Chapter covers the basic information on those physical, biological, and sociological characteristics of the area environment that might be affected by the construction and operation of a power plant on the proposed site as well as clustered associated facilities such as a coal unloading facility. More linear features which leave the main site proper and need rights-of-ways or siting corridors (e.g., rail spurs or transmission lines) should be addressed in Chapter 6.

2.1 Site and Associated Facilities Delineation

   On topographical maps of at least 1:24000 scale, show the perimeter of the site and associated facilities, and identify abutting and adjacent properties. Indicate total site acreage owned by the applicant or that is proposed to be obtained. Indicate that part to be occupied or altered by the plant and associated facilities. Indicate other existing and proposed uses, if known, of the applicant's property both before and after construction of the new plant and associated facilities. Indicate the acreage devoted to those uses. Indicate whether any portion of the site or associated facility lands are within the 100-year flood zone.

Also, where the information is readily available, identify major private land-holdings for which the primary purpose is environmental protection (e.g., the Nature Conservancy's Corkscrew Swamp).

   Using a 1:24000 scale map, indicate the same for an area of one mile surrounding the plant and clustered associated facilities (to provide greater detail).

   2.2.2 Zoning and Land Use Plans

   Identify local government comprehensive plans adopted pursuant to Ch. 163 F.S. for the jurisdictional area in which the plant and associated facilities are proposed. Indicate on a map how and where the plant and associated facilities will interact with the comprehensive plan land use categories. Briefly evaluate the project in terms of consistency with the Local Government Comprehensive Plans, if adopted.

   As required by F.A.C. Rule 17-17.121(3)(a), submit three copies of a compilation of information specifying the procedures taken to accomplish compliance of the site, including associated facilities, with existing land use plans and zoning ordinances. Such compilation must include copies of the applicable portions of the ordinances, regulations, and land use plans involved.

   2.2.3 Demography and Ongoing Land Use

   Indicate on a map the existing populations (using appropriate governmental projections) of the towns and cities shown on Section 2.2.1's 5-mile map, or identify them on a separate tabulation.

   Using Level II categories of the Florida Land Use and Cover Classification System, map at a scale of 1:63,360 the existing land use for an area extending five miles from the plant and one mile from any associated facility not covered in Chapter 6. The applicant shall verify the continued validity of data more than 12 months old at the time of filing. More detailed information should be provided along with Section 2.3.5's Vegetation identification.

   Indicate the nature and extent of projected land uses and any recent trends such as abnormal changes (sudden increases or decreases) in population or industrial patterns in the vicinity. Nearby activities that may be affected by the plant construction and operation should be described in greater detail than more distant activities.

   2.2.4 Easements, Title, Agency Works

   Identify any easements or titles which would ordinarily be obtained from any governmental agency. (Please see Introductory Note pertaining to State-owned Lands.) Identify all proposed locations where the utility has traditionally been required to request road, pipeline or waterworks crossing approvals from State or County governments. Also identify rights-of-way which will be crossed and any changes which may be necessary in those ROW features (e.g. roads or canals) to accommodate traversement by plant-related features (e.g., coal conveyors, cogeneration steam pipes, etc.). Long linear features such as rail spurs or transmission lines should be addressed in Chapter 6.

   2.2.5 Regional Scenic, Cultural and Natural Landmarks

   Describe the areas identified in section 2.2.1 located within five miles of the site and associated facilities not covered in Chapter 6 which are valued as landmarks for their natural, scenic, or cultural significance that may be affected by the plant and its emissions. Include a brief discussion of the inherent significance, if any, of the site or adjacent areas.

   2.2.6 Archaeological and Historic Sites

   Indicate whether or not the site or associated facilities have any archaeologically or historically significant sites or areas considered to be potentially significant archaeologically or historically, above or below water, as identified by the Department of State, Division of Archives, History and Records Management (DAHRM). Significance will be determined in terms of the criteria presented in 36 C.F.R. 63 "Determinations of Eligibility for Inclusion in the National Register of Historic Places". Describe the methods used in making archaeological and historical studies of the site. Methods must be acceptable to the DAHRM. Copies of reports resulting from such surveys should be submitted to DAHRM.

   2.2.7 Socioeconomics and Public Services

   Provide a brief background discussion on the following topics as they relate to the area where the main plant and associated facilities will be located:

      Social and Economic Characteristics -- Labor Force; Employment by Occupation; Employment by Industrial Sector; Baseline Employment Projections; General Income Characteristics; Source of Income; Average wage and salary income, by sector; Baseline income projections; Housing; Existing housing stock; Building activity; and, Housing costs.

      Area Public Service and Utilities -- Education; Transportation; Medical Facilities; Fire Fighting Facilities; Police Protection; Recreation facilities; Electricity and gas; Water supply facilities; Sewage treatment facilities; and, Solid waste disposal.

2.3 Bio-Physical Environment

   Provide the information listed in the following sections. For those facilities located within the jurisdiction of a water management district which has specific review criteria required by rule then any data required by that rule but not iterated below must also be submitted. Pre-application consultation with the District is suggested.

   2.3.1 Geohydrology

   Describe the major geological aspects of the site and associated facility areas as outlined below, including a description of the geological and soil studies designed to determine the suitability of the site. The description should include identification of the sampling pattern and the justification for its selection, the sampling method, pre-analysis treatment, and analytic techniques. When used, previously published geological and soil studies should be briefly summarized. The level of detail for this section should be appropriate to the plant design. For example, if no holding or cooling ponds, ash ponds, FGD sludge or coal piles, etc., are to be created, then some of the information outlined may be omitted.

      2.3.1.1 Geologic Description of the Site-Area

      Provide a general geological description of the site area. This may be in the form of a stratigraphic section taken from available publications and should include formation names, lithologic descriptions, thickness information and average depth below land surface.

      2.3.1.2 Detailed Site Lithologic Description

      The following information should be developed from exploratory boreholes installed on site (holes can be used for initial groundwater monitoring wells if so desired):

      Geologic borehole logs (a continuous lithologic description from land surface through the top of the rock) detailing the depth to and elevation of the top of each lithologic unit; the thickness of each lithologic unit; the grain size analysis of each lithology; the porosity for each lithology; vertical and horizontal hydraulic conductivities for each lithology; and cation exchange capacity for clayey material. Site soils should also be described according to their soil classifications.

      Data summarizing the driller's logs of the boreholes should be included. Two copies of actual logs must be submitted. These should provide information on the location and approximate elevation; the size and depth of the hole; date drilled; driller's name; method of drilling; drilling rate or effort; loss of circulation with estimated percentage of loss and reason for loss; ground water level; method of sampling; depth at which samples were taken; and method of hole abandonment if applicable, including volume of materials required to fill the hole.

      Provide geologic cross sections through the site (developed from geologic boreholes). These cross sections should indicate the continuity of the lithologic units throughout the site.

      2.3.1.3 Geologic Maps

      For appropriate portions of the site (e.g., where structures, ponds, or storage areas are proposed or where spills are likely to occur) indicate the top of significant geologic units and isopachs of significant geologic units; provide a fracture trace analysis. Soils or geologic features which could be used to attenuate contaminants from leachate or runoff should be highlighted.

      2.3.1.4 Bearing Strength

      For proposed sites at which bearing strength may be an issue, provide a foundation suitability assessment. For sites where no such assessment is provided, briefly explain why bearing strength is not considered significant.

   2.3.2 Subsurface Hydrology

   As outlined below, describe the physical, chemical and hydrological characteristics (and their seasonal variations) of subsurface waters that will be affected by plant effluents or that will be affected by the construction or operation of the proposed plant and associated facilities.

      2.3.2.1 Subsurface Hydrologic Data for the Site

      Describe the shallow water table aquifer with a water table contour map; maximum and minimum recorded water table elevation; vertical and horizontal gradients; estimated rate of groundwater flow; directions of groundwater flow; the aquifer's relationship to local geology; background water quality; and aquifer characteristics including specific yield, hydraulic conductivity, thickness, and water quality classifications.

   Characterize other potentially impacted aquifers by providing potentiometric surface maps to the nearest foot for wet and dry seasons. Also discuss gradient; estimated rate of groundwater flow; estimated direction of groundwater flow;

estimated yearly recharge from overlying hydrogeologic units; aquifer characteristics including thickness, transmissivity, and storativity; utilization for water supply; discharge features associated with the aquifer; and background water quality.

   Characterize the confining units hydrologic characteristics including thickness, vertical hydraulic conductivity, storativity, hydraulic head at the top and bottom of the confining unit, and leakage rate. Also describe the continuity of the unit throughout the site and general area.

      2.3.2.2 Karst Hydrogeology

      Where paleokarst features potentially affect the hydrology of the site, the following approach is recommended:

      Perform a detailed fracture trace analysis using black and white and infrared aerial photography and topographic maps. All apparent sink features in the general area should be located and mapped. Photolinear features delineated by the analysis should then be ground-truthed and mapped. A reconnaissance survey using geophysical techniques should be performed with special emphasis placed on features identified by the fracture trace analysis. Where applicable, ground penetrating radar and/or other electromagnetic methods appear to be the most rapid and cost-approach to these type of investigations. On the basis of the initial geophysical reconnaissance and the fracture trace analysis one or more geophysical methods should be employed to specifically locate test borings to verify anomalous geophysical features.

   2.3.3 Site Water Budget and Area Uses

   Using the most representative data for the site, provide the following information, giving sources:

   Data on rainfall, including both average yearly and monthly averages; average monthly temperature; estimated yearly evapotranspiration; estimated yearly evaporation; estimated yearly runoff; estimated peak runoff; and estimated yearly groundwater recharge.

   Discuss the nature and amounts of present major water uses such as community water supplies, agricultural irrigation, reservoirs, recreation and transportation. Also, to the extent the necessary information is available from public records, discuss the sources (surface water or aquifer) of these waters within a five-mile radius of the main plant site. Show the major impacted sources including withdrawal points. Include the source of information concerning the surrounding major water users, i.e. water management district permits, U.S.G.S. surveys, etc., on a map. Identify the location of all potable water wells currently in use within one mile of the site, and where such information is readily available, provide more detailed information on size, depth, casing (including depth and type), average withdrawal rates, construction details, and water use. In the case of difficulties in obtaining private well information, the applicant should consult with the Department and the appropriate water management district as to sufficient alternative information.

   2.3.4 Surficial Hydrology

      2.3.4.1 Hydrologic Characterization

      Describe the physical, chemical, and hydrological characteristics including seasonal variations, of surface waters that will be affected by plant effluents or stormwater or that will be affected by the construction or operation of the proposed plant and associated facilities. The description should include the water classification designated in Chapter 17-3, F.A.C. Include a general description of significant tributaries (those shown on USGS 7.5 and 15 minute quadrangle maps) affected by the site including associated facilities, and the pattern and gradients of drainage in the area. Information on water characteristics should include measurements, to the extent possible, made on or in close proximity to the site.

      Discuss the maxima, averages and minima of important parameters of those surface waters which may be affected by construction or operation of the plant. Include where applicable: flow rate, velocity, water table elevation above mean sea level, chemical characteristics, temperature, circulation patterns, mixing characteristics, river and lake levels, tides, floods, currents, wave action and flushing times, and volumes of flows in and out of lake systems.

      Indicate how volumes and areas of surface waters change with expected seasonal and other water level fluctuations. When a stream or other water body would be used by the plant, provide the available mean, low, and high flow values. Establish vertical and areal variations for the area affected by the site. When using historical data, cover a ten-year period or the period of record if less than ten years of normal, high and low flow hydrological conditions.

      2.3.4.2 Measurement Programs

      Describe the programs and methods for measuring background physical and chemical parameters of surface waters which will be affected during construction and/or operation of the facility. The sampling program should be presented in sufficient detail to demonstrate its adequacy with respect both

to spatial coverage (surface area and depth) and to temporal coverage (durations and sampling frequency), and to give due consideration to seasonal effect. Also describe any computational models used in predicting effects. Indicate how models were verified and calibrated.

   2.3.5 Vegetation/Land Use

   This chapter should discuss the expected environmental effects of site preparation and construction of the plant and associated facilities. The effects should be presented in terms of their physical impact on the resources and populations described in Chapter 2 and in terms of compliance with the non-procedural standards of any affected agency.

   In the applicant's discussion of environmental effects, it should be made clear which of these effects are considered unavoidable and irreversible. Those effects which represent an irretrievable commitment of resources should receive detailed consideration in Section 4.4. In the context of this discussion, "irretrievable commitment of resources" alludes to natural resources and means a permanent impairment of these resources, e.g., loss of wildlife habitat; impairment of nesting, breeding or nursery areas; interference with migratory routes; damage to archaeological or historic sites; and, loss of valuable natural areas, as well as the expenditure of directly utilized resources. Mitigative measures to reduce or eliminate any impacts should be discussed where appropriate under each category in Sections 4.1 through 4.9.

   In each section indicate the specific environmental effects, if any, which the applicant proposes to monitor during plant construction. Where post-application monitoring is proposed to be the same as pre-application monitoring, include a statement referring to the appropriate subsection of Chapter 2. Proposed changes from pre-application monitoring should be addressed. Sample station, location, sampling frequency, methodology, (including calibration and checks with standards) and instrumentation for both collection and analysis should be thoroughly discussed. Information should be provided on instrument accuracy, sensitivity and especially, the reliability of highly automated systems. Standard analytical or other techniques used by the Department of Environmental Regulation should be used or permission to modify the techniques must be obtained.

Activities that might affect water use include the construction of cofferdams or storm sewers, dredging operations, borrow pits, placement of fill material in the water, and the creation of shoreside facilities involving bulkheads, piers, jetties, basins or other structures enabling ingress or egress from the plant by water. Examples of other pertinent activities are construction of intake and discharge structures for cooling water or other purposes, straightening or deepening a water channel, and operations affecting water levels (flooding), construction, etc. The applicant should describe the effects of these activities on navigation, fish and wildlife resources, water quality, water supply, and aesthetics. Where it is proposed to create a cooling water lake, describe the effects on the local ecology, including the loss of flora and loss or gain of habitat for migratory and resident fish and wildlife in the area the lake will occupy. Where applicable, any program for the establishment, development or control of aquatic plant and animal life should be described. This discussion may reference any available data based on studies of similarly sited artificial lakes. If excavations are made for cooling ponds or canals, describe the type and volume of material to be removed and the method and site of its ultimate disposal.

CHAPTER 5

EFFECTS OF PLANT OPERATION

   This chapter should describe (1) the operational interaction of the plant and clustered associated facilities with the environment, and (2) the applicant's plans and programs for monitoring the environmental impacts resulting from plant operation. The effect of plant operation shall be discussed in the context of the non-procedural standards of any affected agency. The applicant is not required to repeat the material presented in Chapters 2 and 3, but such previously presented material should be cross-referenced. Effects of plant operation on the environment should be described in detail. In the discussion of environmental effects, effects that are considered unavoidable but are either temporary or subject to later amelioration should be clearly distinguished from those regarded as unavoidable and irreversible. Mitigation efforts and effects should be described where applicable.

   The impacts of operation of the facility should be, to the extent practicable, quantified and systematically presented. The source of each impact, i.e., plant subsystems (types and sizes) and waste effluents, and the population or resource affected should be made clear in each case. Impacts due to failure of control devices should be estimated. In the discussion of each impact, the applicant should make clear whether the supporting evidence is based on theoretical, laboratory, on-site, or field studies undertaken on this or on previous occasions.

   The applicant should discuss the relationship between local "short term" and "long term" effects. ("Short term" effects refer to the operational life of the proposed facility and "long-term" effects refer to time periods extending beyond the life of the plant). The applicant should also discuss the reasons for any requested variances.

   The description of the programs for operational monitoring should include a thorough discussion of the number of sampling stations and their locations, sampling frequency, methodology, (including calibration and checks with standards) and instrumentation for both collection and analysis. Information should be provided on instrument accuracy, sensitivity and, especially, the reliability of highly automated systems. Standard analytical or other techniques as used by the Department of Environmental Regulation should be used or permission to modify the techniques must be obtained.

   As an option, the operational monitoring program may be submitted to the department no later than six months and preferably one year before the plant start-up target date. This option may be exercised by the applicant if the target start-up date is more than two years beyond the anticipated date of site certification.

   Where post application monitoring is the same as pre-application monitoring, a statement referring to the appropriate subsection of Chapter 2 will be acceptable. Changes from pre-application monitoring should be addressed. Where site preparation or facility construction may alter previously measured or observed environmental conditions, the program for monitoring the modified condition should be described. Specific details or raw data of any monitoring programs may be included as an appendix in lieu of listing herein.
