    SUMMARY: We are amending the regulations governing the importation of 
    plants established in growing media to allow the importation of 
    rhododendron from Europe under conditions designed to prevent the 
    introduction of dangerous plant pests. This action will relieve 
    restrictions on the importation of rhododendron plants from Europe 
    while continuing to protect against introduction of plant pests.
    
    EFFECTIVE DATE: December 30, 1999.

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        The regulations in 7 CFR part 319 prohibit or restrict the 
    importation of plants, plant parts, and plant products into the United 
    States to prevent the introduction of plant pests. The regulations 
    contained in ``Subpart--Nursery Stock, Plants, Roots, Bulbs, Seeds, and 
    Other Plant Products,'' Secs. 319.37 through 319.37-14 (referred to 
    below as the regulations), prohibit or restrict, among other things, 
    the importation of living plants, plant parts, and seeds for 
    propagation.
        Section 319.37-8, paragraph (a) of the regulations requires, with 
    certain exceptions, that plants offered for importation into the United 
    States be free of sand, soil, earth, and other growing media. This 
    requirement is intended to help prevent the introduction of plant pests 
    that might be present in the growing media; the exceptions to the 
    requirement take into account factors that mitigate that plant pest 
    risk. Those exceptions, which are found in paragraphs (b) through (e) 
    of Sec. 319.37-8, consider either the origin of the plants and growing 
    media (paragraph (b)), the nature of the growing media (paragraphs (c) 
    and (d)), or the use of a combination of growing conditions, approved 
    media, inspections, and other requirements (paragraph (e)).
        On September 7, 1993, we published in the Federal Register (58 FR 
    47074-47084, Docket No. 89-154-1) a proposed rule to amend the 
    regulations to allow the importation of five genera of plants 
    established in growing media. That proposal is referred to below as 
    ``the proposed rule.'' We accepted comments on the proposed rule for a 
    period of 90 days, ending December 6, 1993.
        In a final rule published in the Federal Register on January 13, 
    1995, and effective on February 13, 1995 (60 FR 3067-3078, Docket No. 
    89-154-2), the Animal and Plant Health Inspection Service (APHIS) 
    finalized provisions for the importation of Alstroemeria, Ananas, 
    Anthurium, and Nidularium species. The final rule postponed action on 
    Rhododendron species established in growing media to allow consultation 
    regarding the action with the U.S. Fish and Wildlife Service, in 
    accordance with the Endangered Species Act.
        On April 30, 1998, we published in the Federal Register (63 FR 
    23683-23685, Docket No. 89-154-3) a notice reopening and extending the 
    comment period on the proposal to allow the importation of Rhododendron 
    species established in growing media. The notice also announced that, 
    as a result of formal consultation with the Fish and Wildlife Service 
    in accordance with Section 7 of the Endangered Species Act, APHIS 
    intended to limit the proposed action to Rhododendron species imported 
    from Europe only. The limitation to Europe was made because there is 
    little importation of rhododendron from places outside Europe, and 
    limited data on pests of rhododendron outside Europe. We believe the 
    data available on rhododendron pest distribution outside Europe, and 
    pest interceptions on rhododendron commodities from outside Europe, is 
    insufficient to support a conclusion of negligible risk for importation 
    of rhododendron from all countries at this time.
        Comments were required to be received on or before June 1, 1998. We 
    received two requests from trade organizations to extend the period 
    during which comments would be accepted. In response, on June 1, 1998, 
    we published in the Federal Register (63 FR 29675-29676, Docket No. 89-
    154-4) a notice extending the comment period until July 30, 1998.
        During this reopened comment period of April 30 through July 30, 
    1998, we received 11 comments on the rhododendron proposal. 
    Additionally, we received approximately 60 comments from domestic 
    nurseries and nursery associations, importers, State governments, and 
    environmental interest groups during the original 1993 comment period 
    on the proposed rule that specifically addressed importation of 
    rhododendron. The issues addressed by all of these comments are 
    discussed below.
        Comment: APHIS identified rhododendron pests of concern for this 
    rule using reports from the scientific literature and reports of pest 
    interceptions associated with rhododendron at ports under the
    
    [[Page 66711]]
    
    premise that these sources would reveal all pests of concern. This 
    premise is fallacious because the lack of citations in the scientific 
    literature may merely reflect scientists not choosing to address pests 
    that attack rhododendron, and a lack of interception reports may 
    reflect the small amount of trade in rhododendron in growing media. 
    This approach misses potential pest problems.
        Response: The purpose of the literature search and review of 
    interception reports was to identify all known pests of concern and to 
    collate information about these pests that would also allow us to make 
    informed assumptions concerning potential unknown pests of concern. 
    Pest risk analysis is a combination of the processes of pest risk 
    assessment (determining whether a pest is harmful and evaluating its 
    introduction potential) and pest risk management (the decision-making 
    process of reducing the risk of introduction of a quarantine pest). It 
    is standard scientific procedure in conducting a pest risk assessment 
    to review the available scientific literature and interception records, 
    conduct surveys, and communicate with foreign and domestic scientists 
    and government officials. The process of pest risk assessment is a 
    well-established procedure within APHIS. Some of the earliest pest risk 
    assessments were done over 75 years ago and have proved their utility 
    over time, because program requirements based on them have successfully 
    excluded or controlled the quarantine pests that were the targets of 
    the assessments.
        When conducting a pest risk assessment, the relative richness or 
    paucity of information on particular pests is a factor in the analysis. 
    If in-depth pest data is lacking and there is reason to believe pests 
    of concern are not well characterized, the assessment employs 
    conservative assumptions that maximize the potential hazard presented 
    by the uncharacterized pests.
        Scientists choose to study particular pests for a variety of 
    reasons, but economic factors clearly direct much scientific research 
    toward pests of economic importance. Pests of rhododendron and other 
    major ornamental plants are clearly of economic importance, and a great 
    deal of research has in fact been directed toward these pests.
        Interception records vary with the commodity, source, volume, host 
    susceptibility, and other factors. Rhododendron have been imported from 
    Europe in varying amounts for over 50 years, both as cargo and in 
    passenger baggage. Most of the pest interceptions have been made in 
    passenger baggage, presumably in plants taken from the wild. It is true 
    that there are few records of interception of pests associated with 
    commercial importation of rhododendron because our regulations have 
    previously prohibited importation of rhododendron in soil or growing 
    media, and there is limited commercial incentive to import bare-rooted 
    plants. We believe it is unproductive for commenters to support 
    limiting rhododendron imports to bare-rooted plants only, and then to 
    argue that to justify importing the plants in growing media we would 
    need years of interception records for this (prohibited) trade in 
    rhododendron in growing media. When considering changes to the 
    regulations, we cannot collect data about activities we have prohibited 
    (except for occasional data about shipments smuggled in violation of 
    the regulations).
        Overall, we believe there is sufficient pest information about 
    which pests occur in Europe and in the United States to analyze the 
    pest risk and reach a sound biological decision on how to handle the 
    rhododendron in growing media.
        Comment: APHIS wrongly evaluated pests based on their known damage 
    potential. Many pests now causing harm in the United States were 
    innocuous in their place of origin and only caused significant harm 
    when introduced into an area free of their natural enemies.
        Response: One of the elements of pest risk assessment is an 
    evaluation of the potential damage that may be caused by a pest using a 
    set of criteria. While some introduced pests have found a favorable 
    niche in the United States, others have never become serious pests. The 
    establishment of a pest is determined by many factors, such as climate, 
    survival, finding a suitable host, etc., which are considered in a pest 
    risk assessment. The absence of natural enemies may play an important 
    role in the establishment of a pest, especially for insects. APHIS is 
    well aware of this natural phenomenon and has considered it in 
    conducting its pest risk assessments. The basis of a good quarantine 
    system is to prevent the introduction of the pests before they reach 
    our shores.
        Comment: The short-spored rhododendron rust caused by Chrysomyxa 
    ledi var. rhododendri should be considered a pest of quarantine 
    significance, as it causes serious defoliation and its spores are 
    spread by wind. Presence of this disease would not be revealed by the 
    proposal's greenhouse growing requirements, and the Kahn report (a 
    report of the APHIS committee of researchers who prepared worksheets on 
    pests and evaluations of pest risk prior to this rulemaking) notes that 
    ``if the host/rust interaction were in the incubation period at the 
    time of inspection, the infection would not be detected.''
        Response: APHIS considers Chrysomyxa ledi var. rhododendri a 
    quarantine pest because it can cause economic losses to both 
    Rhododendron and Picea species. When it is detected on intercepted 
    plant material, the plant material is seized and destroyed. Concerning 
    its epidemiology and other characteristics, the fungus may cause 
    defoliation and the spores are indeed spread by wind, like most rusts. 
    For infection to occur the disease pathway must lead to the vicinity of 
    a target host. The conditions and safeguards in the proposed rule are 
    sufficient to preclude establishment of the disease in the United 
    States. While there are growth periods when signs of the pathogen are 
    not obvious in the host plant, there are signs of infection visible to 
    close scrutiny. That is the reason for the lengthy observed growing 
    periods required by the proposed rule for both mother stock and 
    progeny: to provide an opportunity to detect incipient infection that 
    might not be obvious during a one-time inspection. Besides the regular 
    surveillance of the plants during the long growing period, the detailed 
    inspection at a U.S. quarantine inspection station at the first port of 
    entry provides additional safety.
        Comment: The proposal cites APHIS' experience in importing plants 
    in media without introducing pests as one basis for the proposal and 
    suggests there have been no problems with plants currently allowed to 
    be imported in media in 20 years. This is not true. Pest movement on 
    plant material used in greenhouse production was the likely cause for 
    spread of a serpentine leafminer (Liriomyza trifoili (Burgess)), a pea 
    leafminer (L. huidobrensis (Blanchard)), the beet armyworm (Spodoptera 
    exigua (Hubner)), the western flower thrips (Frankliniella occidentalis 
    (Pergrande)), and the sweetpotato whitefly (Bemisia tabaci 
    (Gennadius)). Also, in comments on an earlier rule, Dr. Ken Horst 
    identified several cases where U.S. growers had to destroy material 
    imported in media due to disease. Also, simply pointing to the 
    successes of the current program does not justify extending it.
        Response: The experience of growing certain plants in growing 
    media, as cited by APHIS, forms the basis of a model for a systems 
    approach that uses modern and advanced horticultural practices to
    
    [[Page 66712]]
    
    prevent the introduction and spread of plant pests. The commenter 
    correctly identifies pest movement on plant material used in greenhouse 
    production as the likely cause for the spread of the enumerated pests, 
    and we do not doubt that those and other pests have spread from 
    unregulated greenhouse cultivation where infested plants were grown. 
    The growing of plant material under controlled conditions such as those 
    in the regulations will prevent or greatly reduce the spread and 
    movement of plant pests. The pests cited by the commenter did not 
    originate from greenhouse cultivation under the system described in the 
    proposal. Greenhouse production in accordance with the proposed 
    regulations would have prevented the dissemination of such pests.
        APHIS is not aware of the details of the specific cases where U.S. 
    growers had to destroy material imported in media due to disease as 
    reported by Dr. Ken Horst, because the entry of these pests apparently 
    was not reported to APHIS or State quarantine officials at the time of 
    their discovery. When a quarantine pest is discovered, it should be 
    reported immediately to APHIS or State quarantine officials so its 
    eradication can be confirmed and the pathway of entry studied. Since 
    APHIS did not have the opportunity to investigate these cases at the 
    time, APHIS cannot comment on the incidents cited by the commenter.
        Comment: The current state of the science of risk analysis still 
    acknowledges major areas of uncertainty when it comes to assessing the 
    actual impacts of new pest introductions; the full extent of the damage 
    they may cause cannot be accurately estimated. This uncertainty makes 
    it unwise to adopt the proposed action for rhododendron.
        Response: Pest risk analysis is the best tool currently available 
    to evaluate and manage pest risk. It is being standardized, refined, 
    and promoted globally. Uncertainties are acknowledged in the risk 
    analysis process, and for this reason APHIS uses great care in arriving 
    at its decisions and involves the best and most competent risk analysts 
    available to the agency among its staff and outside resources. While 
    all the information about pest damage caused to rhododendron may not be 
    fully known, there is sufficient and reliable information to evaluate 
    importing rhododendron under the conditions we proposed. Should pest 
    risk change at any time, APHIS is prepared to change any or all aspects 
    of the program, including denying approval of greenhouses, shutting 
    them down, or making any other changes necessary to the program to 
    safeguard the United States against invading pests.
        Comment: Increasingly, APHIS quarantine decisions appear to be 
    driven by trade policy (attempting to expand and liberalize 
    opportunities for international trade under the World Trade 
    Organization agreement) rather than the primary APHIS mandate of pest 
    prevention based on science. We believe, consistent with the Office of 
    Technology Assessment report, ``Agriculture, Trade, and the 
    Environment: Achieving Complimentary Policies,'' that APHIS should not 
    try to achieve an unrealistic zero risk standard, but should seek to 
    target controls to protect those agricultural systems that are at 
    greatest risk from harmful nonindigenous species. We further believe 
    that nursery crops represent an ``at greatest risk'' category with 
    regard to pests associated with foreign rhododendron in media.
        Response: APHIS' first and primary responsibility is to protect 
    U.S. agriculture from foreign quarantine pests. The United States is a 
    signatory to World Trade Organization (WTO) agreements and is bound to 
    comply with certain WTO policies guiding national activities to protect 
    plant health, and it expects that other countries do the same. The 
    United States strongly supports and sponsors initiatives to achieve 
    global standardization in plant quarantine activities. APHIS is 
    applying these standards in complying with the agreements, which is in 
    the interest of U.S. agriculture. Nursery stock has been, and continues 
    to be, an area of great concern to APHIS. We attempt to employ the most 
    effective, practical, and cost-effective strategies to prevent the 
    introduction of plant pests, including exclusion of the host plant when 
    necessary. We do not and cannot employ a ``zero risk standard.'' It is 
    not possible to eliminate all risk. We reduce risk to a negligible 
    level. Our regulations establish controls and prioritize agency 
    resources to maximize protection to those agricultural systems that are 
    at greatest risk.
        Comment: The proposed visual inspection of stock in participating 
    European greenhouses would be largely ineffective because many pests 
    are not readily found by inspection at some life stages.
        Response: In this rule APHIS requires a lengthy pre-importation 
    detention period or holding period in the greenhouses in foreign 
    countries. This should give plant inspectors time for inspection and 
    evaluation of plants and facilities to determine whether the 
    rhododendron plant material meets entry requirements. By the same 
    token, this long detention period allows more time for the development 
    of pests so that they may be visible to the inspector. If the inspector 
    determines that methods other than a visual inspection are necessary to 
    determine the presence of a pest, then suspect material may be 
    investigated, detained, treated, tested, etc. Additionally, all 
    shipments of rhododendron will be directed to an APHIS Plant Inspection 
    Station at a port of entry for inspection and final release.
        Comment: The proposed pesticide dip offers no detail on active 
    ingredient, rate, or efficacy against pests. Also, in some cases, 
    pesticide treatments may mask, but not eliminate, pest presence.
        Response: APHIS does not normally include informational details of 
    a pesticide such as active ingredients, dose rate, or efficacy against 
    pests in a rule because, in many cases, to do so would be to repeat a 
    large volume of scientific and testing data that was used in the 
    process of approving the pesticide for use against targeted pests. The 
    approval process for pesticides is a separate function of other Federal 
    agencies and agencies of foreign governments. APHIS' discussion of a 
    pesticide is usually limited to discussing that a pesticide is in fact 
    approved for use against a target pest in a given commodity and that 
    use of the pesticide meets operational needs of APHIS and the affected 
    industry. The exporter is required to use only pesticides prescribed by 
    the plant protection service of the exporting country and must inform 
    the inspector prior to their use. The recommended dip with a pesticide 
    is a precautionary treatment and just one more additional safeguard, so 
    while the masking of pest presence by pesticide use may occasionally be 
    a problem, other components of the systems approach of the regulations 
    compensate for this possible effect. It is APHIS policy that, should 
    the pesticide make inspection difficult or hinder inspection in any 
    way, the shipment or consignment may be denied. Such pesticide dips are 
    not unique to the rhododendron import rule; they are also recommended 
    and are effectively used in the United States on other imported and 
    domestic plant and plant products.
        Comment: Inspection at the port of entry under the best conditions 
    is still not adequate to detect many pests. Further, the reality is 
    that APHIS inspects many cargoes at a rate of less than one-half of one 
    percent, and allows unsound inspection practices such as ``tailgate'' 
    inspections and allowing brokers to select the samples to be
    
    [[Page 66713]]
    
    inspected. Because the proposal partly relies on inspection to mitigate 
    the risks, these inadequacies mean the proposal will not achieve its 
    claimed level of risk reduction.
        Response: Inspection at ports of entry is an internationally 
    accepted strategy in plant quarantine. It is rarely ever used alone, 
    and in addition to visual examination by an inspector, may include any 
    number of techniques to arrive at a decision. In this rule, inspection 
    at the port of entry is not the only, or even primary, protection. 
    Additional safeguards include growing site inspection, monitoring, 
    surveillance, certification, and specific growing conditions in the 
    country of origin to reduce the risk of the introduction of pests to a 
    negligible level. Port of entry inspection of bare-rooted rhododendron 
    has been used successfully for many years. Now that the regulations 
    allow importation of the plants in growing media, we are retaining port 
    of entry inspection but are also requiring additional safeguards.
        The rate or percentages employed by APHIS in the inspection of 
    cargoes varies depending on the pest risk, origin of the commodity, and 
    other factors connected with the type of shipment. An inspection of 100 
    percent of the commodity may be ordered when the conditions warrant. 
    The many thousands of interceptions made by the United States and other 
    countries are evidence that inspection has considerable merit for some 
    pests, but the volume of interceptions is likewise a sign that 
    inspection alone is not enough and that a systems approach that 
    addresses growing conditions in the country of origin is needed to keep 
    dangerous pests that are not visible to inspectors from arriving at 
    U.S. ports. This rule establishes such a systems approach.
        Comment: APHIS bases part of its argument on the lack of pest 
    problems associated with imports of bare-rooted rhododendron in recent 
    years. However, this trade amounts to only a few thousand dollars a 
    year, compared to an expectation of importing many times that volume of 
    plants in media under the proposed rule. The minuscule amount of bare-
    root imports provides no basis for assessing risk.
        Response: APHIS makes a logical comparison between the importation 
    of bare-rooted rhododendron and its importation in approved growing 
    media. If pest problems are not associated with bare-rooted plants, 
    which are grown in the open field and exposed to the environment, one 
    might conclude that the risk is even less when the plants are grown 
    under a system of controlled conditions in a greenhouse--barring the 
    possibility that there are pests associated with the media but not the 
    plant. The proposal included strict media standards to preclude the 
    presence of pests associated with the media. Furthermore, the 
    importation of plants in growing media as proposed should eliminate the 
    occasional pest problems that were associated with importing bare-
    rooted plants, by providing an even safer and economically more 
    attractive method to import rhododendron. Consider that at one time 
    ferns were imported bare-rooted, and there were many pest problems both 
    for the importers and for APHIS. Producing them in growing media under 
    controlled conditions resolved the problems to the satisfaction of both 
    the importers and APHIS. The system for importing ferns in growing 
    media has worked for a large volume of plants imported over an extended 
    period of time. In view of this and the more limited data from 
    importing small volumes of bare-rooted rhododendron over many years, it 
    is reasonable to believe the rule's requirements for importing 
    rhododendron will work.
        Comment: The Endangered Species Act consultation did not assess the 
    risk to listed species other than Rhododendron in the family Ericaceae, 
    such as five Arctostaphylos species that occur in California and may be 
    vulnerable to pests introduced by rhododendron.
        Response: Pest risk assessment for plants is generally done at the 
    genera level, and for this rule it was done for the entire genus 
    Rhododendron. Based on pest and host data collected in the early stages 
    of assessment, projects may be expanded to include other plant genera. 
    If data showed Arctostaphylos to be a host of any of the pests 
    associated with Rhododendron, the genus would have been seriously 
    considered in the analysis. We have not received any specific pest or 
    host data in comments and are not aware of any that indicates it is 
    necessary to perform an assessment for the entire family Ericaceae. The 
    Fish and Wildlife Service was a great help in evaluating any effects 
    pests of rhododendron would have on endangered species. Consultation 
    with the Fish and Wildlife Service was a valid and legally mandated 
    approach to reaching an understanding of these matters.
        Comment: The pest risk potential associated with imported 
    rhododendron will remain largely unknown and uncharacterized until 
    APHIS performs additional pest risk analyses, particularly focused on 
    horticultural and environmental impacts, to determine the possible 
    impact on all hosts, both native and agricultural.
        Response: Pest risk analysis follows specific guidelines in order 
    that the assessments may be as uniform and consistent as possible. When 
    circumstances warrant, there may be a reevaluation of the pest risk. It 
    would appear from the investigation, reviews, and evaluations already 
    conducted for rhododendron that an additional pest risk assessment at 
    this time is not necessary, particularly in the absence of new data or 
    pertinent information on pest risk. The importation of rhododendron in 
    growing media under the prescribed conditions is limited to imports 
    from Europe. The cultivation practices used for rhododendron in Europe, 
    and the environmental effects of the horticulture and pest issues 
    associated with it, are fairly well known and were considered in 
    analyzing pest risk. No number of additional pest risk assessments 
    could ever give us the precise effect of all possible introduction 
    scenarios on all U.S. hosts, both native and agricultural.
        Comment: The proposed 0.2 mm screen size for greenhouses will not 
    adequately prevent the entry of airborne pests or pathogens without 
    additional requirements for door openings, air filtration systems, etc. 
    The Zandvoort paper, ``Wind Dispersal of Puccinia horiana of 
    Chrysanthemum,'' clearly illustrates how rust spores can easily enter 
    and exit greenhouses via ventilation windows, for example.
        Response: The proposed 0.2 mm screen size for greenhouses is 
    intended for those vents where outside air is necessary. The 0.2 mm 
    screen size is considered very small. It is so small that many believe 
    it to be a hindrance to adequate air circulation. It is a much smaller 
    opening than has been approved for other genera now permitted to be 
    grown in media. The very small screen size and the additional 
    safeguards for greenhouses growing plants in media are believed to be 
    more than satisfactory.
        Regarding door openings, Sec. 319.37-8(e)(2)(ii) of the regulations 
    requires that greenhouses be equipped with automatic closing doors to 
    reduce pest entry into the greenhouses. This requirement was intended 
    to limit the entry of both insects and wind-borne spores through 
    entryways. Based on this comment, we have reexamined options for 
    greater quarantine security at entryways, and have concluded that it is 
    advisable to require a double-door system for all greenhouses growing 
    articles in accordance with Sec. 319.37-8(e). We also have discovered 
    that, for some years, the inspectors employed by
    
    [[Page 66714]]
    
    plant protection services in Europe who inspect and approve greenhouses 
    and mother stock in accordance with the regulations have been enforcing 
    a double-door requirement. Therefore, requiring double doors would 
    improve greenhouse security without adding any expense for greenhouses 
    already growing articles in accordance with the regulations. Since this 
    final rule only addresses requirements for rhododendron, at this time 
    we are amending the greenhouse door provision only for greenhouses 
    growing rhododendron articles, but we intend to initiate rulemaking to 
    require double doors for all greenhouses growing articles in accordance 
    with Sec. 319.37-8(e). This final rule requires that for Rhododendron 
    species only, the plants must be grown solely in a greenhouse equipped 
    with automatic closing double doors of an airlock type, so that 
    whenever one of the doors in an entryway is open the other is closed. 
    This automatic double door requirement will create an additional 
    barrier in the entryway.
        APHIS only requires air filtration systems and other extreme forms 
    of containment for high risk quarantine facilities that are used to 
    maintain high risk material and dangerous pests. These must be 
    constructed in the manner described by the commenter to prevent the 
    escape of dangerous pests. We do not believe such a high level of 
    security is appropriate for greenhouses growing plants from healthy 
    stock where the plants are under surveillance for pests and disease 
    over a considerable period, as required for rhododendron. Should 
    serious pests or diseases be discovered in a greenhouse operating under 
    this rule, additional containment requirements will be imposed as 
    needed. Should the pest risk for growing rhododendron at any location 
    or site be elevated for any reason, the greenhouses for growing them 
    will not be approved.
        The Zandvoort paper, ``Wind Dispersal of Puccinia horiana of 
    Chrysanthemum,'' is not contested. Puccinia horiana is a fast moving 
    rust and has largely been distributed with planting material around the 
    globe. This distribution, however, resulted from international trade in 
    chrysanthemums under conditions far less stringent than those required 
    for importing rhododendron into the United States.
        Therefore, for the reasons given in the proposed rule and in this 
    document, we are adopting the proposed rule as a final rule, and are 
    adding the requirement of automatic closing double doors in 
    greenhouses. We are also making minor, nonsubstantive word changes.
    
    Executive Order 12866 and the Regulatory Flexibility Act
    
        This rule has been reviewed under Executive Order 12866. The rule 
    has been determined to be significant for the purposes of Executive 
    Order 12866 and, therefore, has been reviewed by the Office of 
    Management and Budget. We have prepared a final regulatory flexibility 
    analysis and cost-benefit analysis for the rule, which are summarized 
    below.
        This final rule allows Rhododendron spp. to be imported from Europe 
    in growing media if the plants are grown in secure greenhouses and meet 
    other conditions to exclude plant pests and diseases. This action was 
    originally proposed on September 7, 1993 (58 FR 47074-47084, Docket No. 
    89-154-1) as part of a proposal to allow importation from all countries 
    of five genera of plants in growing media. Based on comments, action on 
    Rhododendron spp. was deferred while an Endangered Species Act 
    consultation was performed between APHIS and the U.S. Fish and Wildlife 
    Service (FWS). Importation of the other four genera (Alstroemeria, 
    Ananas, Anthurium, and Nidularium) has been allowed since the effective 
    date of the final rule published on January 13, 1995 (60 FR 3067-3078, 
    Docket No. 89-154-2). APHIS recently concluded its consultation with 
    the FWS and determined that there were no endangered species concerns 
    that would preclude importing potted Rhododendron spp. from Europe.
        Comments on the initial regulatory flexibility analysis indicated 
    that there is little existing economic data on import trade in plants 
    in growing media and that neither risks nor economic effects can be 
    projected on the basis of the small amount of data available for this 
    trade. This fact is acknowledged in the risk assessments prepared for 
    this action and in the economic analysis below, which explain our 
    analytical basis for projecting risks and economic effects. No changes 
    to the proposed requirements were made based on these comments.
        Alleviating unnecessary quarantine restrictions often can be 
    equated to elimination of trade barriers. Removal of trade barriers has 
    two broad economic objectives. First, freer trade between countries 
    results in lower consumer prices and increases the variety and quality 
    of goods and services available in the local economy. Second, freer 
    trade encourages a nation's resources to be invested in areas of 
    comparative advantage. This enhances the economic well-being of all 
    countries.
        U.S. consumers are direct beneficiaries of government policies that 
    promote freer trade. Domestic consumers benefit by having access to 
    higher quality goods and services at lower prices. Freer trade 
    increases consumer purchasing power by lowering prices and eliminating 
    the deadweight loss associated with quarantine restrictions and other 
    trade barriers.
        Relaxation of trade barriers also results in changes in producer 
    revenue. The amount of total producer income can increase or decrease 
    depending on the elasticity of demand. When U.S. trade restrictions are 
    lifted, a portion of industry profit will be transferred from domestic 
    to foreign producers. Additionally, any increase in the amount of total 
    producer income will go to foreign producers.
        The economic effects on producers and consumers of potted 
    Rhododendron spp. can be analyzed by comparing potential changes in 
    consumer and producer surpluses. Producer surplus is measured by 
    estimating the changes in profit (economic rent) based on potential 
    fluctuations in product prices and quantities. Consumer surplus is the 
    change in aggregate purchasing power and consumer utility when the 
    price and quantity of goods change. An increase (decrease) in supply 
    will decrease (increase) prices and translate into an increase 
    (decrease) in consumer purchasing power (consumer surplus). The net 
    effect on society of regulatory changes is the sum of the estimated 
    changes in consumer and producer surpluses.
        This analysis focuses on the U.S. wholesale plant market. 
    Therefore, domestic consumers of potted Rhododendron spp. include 
    retail firms, landscape brokers, contractors, dealers, and other retail 
    or garden centers.
        Initially, APHIS does not expect this rule to have an economic 
    effect on the domestic potted plant market because phytosanitary 
    restrictions will preclude any increased availability of imported 
    Rhododendron spp. in the domestic market. European producers will be 
    required to meet stringent phytosanitary standards before plants can be 
    shipped to the United States. To date, no European facilities have 
    received APHIS approval to export Rhododendron spp. in growing media to 
    the United States. European producers would likely be required to 
    upgrade existing greenhouses or construct new production units before 
    receiving permission to ship products to the United States. Time will 
    be required for European producers to upgrade and adjust their 
    production practices to meet
    
    [[Page 66715]]
    
    the new requirements. Therefore, APHIS anticipates an 8- to 10-month 
    delay between publication of the final rule and the appearance of 
    potted European-origin Rhododendron spp. in the domestic marketplace.
        The total value of the domestic nursery and floriculture crop 
    (nursery stock, plants, roots, bulbs, seeds, and other plant products) 
    industry is estimated to be about $6.1 billion. This represents about 
    3.7 percent of the value of domestic agriculture.\1\ Annual U.S. 
    floriculture crop sales total about $3.5 billion. Therefore, 
    floriculture crop sales account for about 57.4 percent of total cash 
    receipts for the U.S. nursery and floriculture industry.\2\ The 
    estimated value of annual potted Rhododendron spp. production in the 
    United States totals about $48.3 million annually (Table 1). This 
    accounts for about 1.4 percent of the annual sales volume for domestic 
    floriculture producers.

        Imports of Rhododendron spp. in media would increase the supply and 
    establish a new market equilibrium. A larger quantity of plants would 
    be available at a lower price. Consumer and producer surpluses would be 
    affected by the supply shift. The consumer surplus would be expanded 
    and the producer surplus would increase.
        In summary, this rule will allow U.S. consumers to purchase more 
    potted Rhododendron spp. at lower prices. This increases U.S. consumer 
    welfare and decreases U.S. producer surplus. Therefore, this rule will 
    result in a net welfare gain to U.S. society.
        We developed low- and high-impact scenarios to estimate the 
    potential change in net U.S. welfare. This study assumes that prices 
    will drop by 10 and 30 percent in the low- and high-impact scenarios, 
    respectively (see page 7 of the full economic impact analysis).
        Analysis indicates that this rule will increase net welfare for 
    U.S. society by between $0.339 and $0.484 million when prices are 
    assumed to drop by 10 percent (Table 2). A 10 percent price reduction 
    increases domestic consumer welfare by between $4.933 and $5.078 
    million. However, U.S. producers of Rhododendron spp. will incur 
    welfare losses totaling about $4.595 million (Table 2).
        When prices are reduced by 30 percent, net welfare is increased by 
    between $3.047 and $4.353 million (Table 2). Consumer welfare would be 
    increased by between $15.380 and $16.686 million, and producer welfare 
    would be decreased by about $12.333 million (Table 2).

    --------------------------------------------------------------------------------------------------------------------------------------------------------
    
        The Regulatory Flexibility Act requires that APHIS specifically 
    consider the economic effect of rules on ``small'' business entities. 
    The Small Business Administration (SBA) has set forth size criteria by 
    Standard Industrial Classification (SIC), which was used as a guide in 
    determining which economic entities meet the definition of a ``small'' 
    business. This final rule will have a minor economic effect on small 
    business entities.
        The SBA does not maintain specific size standards for domestic 
    entities that produce potted Rhododendron spp. Therefore, this analysis 
    uses the size standards established for Retail Nurseries, Lawn and 
    Garden Supply Stores (SIC code 5261). The SBA's definition of a 
    ``small'' entity included in the Retail Nurseries, Lawn and Garden 
    Supply Stores classification is one that collects less than $3.5 
    million in annual receipts.
        Rhododendron spp. are grown by about 493 domestic producers (Table 
    1). Nurseries that collect less than $3.5 million in annual receipts 
    are considered ``small'' for the purposes of this analysis. APHIS 
    estimates that all of these nurseries are ``small'' according to the 
    above criteria.\4\ These nurseries are diversified operations that 
    produce many varieties of potted plants and other greenhouse products. 
    Therefore, we anticipate that the rule will not have a significant 
    economic effect on small producers.
    ---------------------------------------------------------------------------
    
        \4\ Note that the definition of a ``small'' nursery has changed 
    since publication of the final rule for importation of Alstroemeria, 
    Ananas, Anthurium, and Nidularium. At that time a ``small'' nursery 
    was defined as having annual sales of $1 million or less.
    ---------------------------------------------------------------------------
    
        The SBA definition of a ``small'' business engaged in the import/
    export business is one that employs no more than 100 employees. The 
    number of
    
    [[Page 66716]]
    
    firms that may qualify as a ``small'' business under this definition 
    cannot be determined. Small importers will likely benefit from the 
    rule. The rule will enable some ``small'' importers to enhance their 
    income through imports of Rhododendron spp. in growing media.
        Small retailers will benefit from importation of Rhododendron spp. 
    in growing media. The rule will enhance the availability and quality of 
    potted plants in the U.S. market. Plant retailers will benefit from 
    lower wholesale prices and will likely pass any savings on to their 
    customers. This would increase annual sales volume and revenue.
    
    Summary
    
        This rule will allow importation from Europe of Rhododendron spp. 
    in growing media. The regulations will require that imported 
    Rhododendron spp. originate from secure greenhouses and meet other 
    conditions to exclude plant pests and diseases.
        During 1997, about 14.2 million potted Rhododendron spp. valued at 
    $48.3 million were produced in the United States.\5\ We developed low- 
    and high-impact scenarios to estimate potential changes in net U.S. 
    welfare. This study assumes that prices will drop by 10 and 30 percent 
    in the low- and high-impact scenarios, respectively.
    ---------------------------------------------------------------------------
    
        \5\ Production data for finished florist azaleas was used as a 
    proxy measure for all domestic Rhododendron spp. production. Nursery 
    azaleas and rhododendron production were not included in this 
    analysis due to data limitations associated with the 1987 Census of 
    Horticultural Specialties.
    ---------------------------------------------------------------------------
    
        This rule will increase net welfare for U.S. society by between 
    $0.339 and $0.484 million if prices drop by 10 percent. The rule will 
    increase the welfare of domestic consumers of Rhododendron spp. by 
    between $4.933 and $5.078 million if prices drop by 10 percent. 
    However, U.S. producers of Rhododendron spp. will incur welfare losses 
    totaling about $4.595 million.
        If prices are reduced by 30 percent, net welfare will increase by 
    between $3.047 and $4.353 million, consumer welfare will increase by 
    between $15.380 and $16.686 million, and producer welfare will decrease 
    by about 12.333 million.
        Rhododendron spp. are grown by about 493 domestic producers. 
    Nurseries that collect less than $3.5 million in annual receipts are 
    considered ``small'' for the purposes of this analysis. APHIS estimates 
    that all of these nurseries are ``small'' according to the above 
    criteria. These nurseries are diversified operations that produce many 
    varieties of potted plants and other greenhouse products. Therefore, we 
    anticipate that the rule will not have a significant economic effect on 
    small producers.
    
    Executive Order 12988
    
        This final rule has been reviewed under under Executive Order 
    12988, Civil Justice Reform. This rule allows the importation from 
    Europe of Rhododendron established in growing media. State and local 
    laws and regulations regarding articles imported under this rule will 
    be preempted while the articles are in foreign commerce. Some nursery 
    stock is imported for immediate distribution and sale to the consuming 
    public and will remain in foreign commerce until sold to the ultimate 
    consumer. The question of when foreign commerce ceases in other cases 
    must be addressed on a case-by-case basis. No retroactive effect will 
    be given to this rule, and this rule will not require administrative 
    proceedings before parties may file suit in court challenging this 
    rule.
    
    National Environmental Policy Act
    
        An environmental assessment and finding of no significant impact 
    have been prepared for this rule. The assessment provides a basis for 
    the conclusion that the importation of Rhododendron from Europe will 
    not present a risk of introducing or disseminating plant pests and will 
    not have a significant impact on the quality of the human environment. 
    Based on the finding of no significant impact, the Administrator of the 
    Animal and Plant Health Inspection Service has determined that an 
    environmental impact statement need not be prepared.
        The environmental assessment and finding of no significant impact 
    were prepared in accordance with: (1) the National Environmental Policy 
    Act of 1969, as amended (NEPA)(42 U.S.C. 4321 et seq.), (2) regulations 
    of the Council on Environmental Quality for implementing the procedural 
    provisions of NEPA (40 CFR parts 1500-1508), (3) USDA regulations 
    implementing NEPA (7 CFR part 1b), and (4) APHIS' NEPA Implementing 
    Procedures (7 CFR part 372).
        Copies of the environmental assessment and finding of no 
    significant impact are available for public inspection at USDA, room 
    1141, South Building, 14th Street and Independence Avenue, SW., 
    Washington, DC, between 8 a.m. and 4:30 p.m., Monday through Friday, 
    except holidays. Persons wishing to inspect copies are requested to 
    call ahead on (202) 690-2817 to facilitate entry into the reading room. 
    In addition, copies may be obtained by writing to the individual listed 
    under FOR FURTHER INFORMATION CONTACT.
    
    Paperwork Reduction Act
    
        This rule contains no new information collection or recordkeeping 
    requirements under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501, 
    et seq.). All information collection requirements associated with this 
    rulemaking have been previously approved by OMB and assigned control 
    number 0579-0049.
