Citrus Seed Imports; Citrus Greening and Citrus Variegated

Chlorosis

AGENCY: Animal and Plant Health Inspection Service, USDA.

ACTION: Interim rule and request for comments.

SUMMARY: We are amending the regulations governing the importation of nursery stock to prohibit the importation of propagative seed of several Rutaceae (citrus family) genera from certain countries where citrus greening or citrus variegated chlorosis (CVC) is present. We are also requiring propagative seed of these genera imported from all other countries to be accompanied by a phytosanitary certificate with an additional declaration that neither citrus greening nor CVC are known to occur in the country where the seed was produced. Scientific evidence indicates that seed of certain genera of the family Rutaceae may be a pathway for the introduction of those diseases. This action is necessary in order to prevent the introduction or dissemination of citrus greening and CVC into or within the United States.

DATES: This interim rule is effective April 6, 2010. We will consider all comments that we receive on or before June 7, 2010.

ADDRESSES: You may submit comments by either of the following methods:

SUPPLEMENTARY INFORMATION:

Background

The regulations in 7 CFR part 319, ``Foreign Quarantine Notices,'' prohibit or restrict the importation of certain plants and plant products to prevent the introduction or dissemination of plant pests and noxious weeds into the United States. The regulations in ``Subpart-

Citrus Canker and Other Citrus Diseases'' (Sec. 319.19) prohibit the importation into the United States of plants and plant parts, except fruit and seeds, of all genera, species, and varieties of the subfamilies Aurantioideae, Rutoideae, and Toddalioideae of the botanical family Rutaceae (citrus) in order to prevent the introduction of citrus canker (Xanthomonas citri subsp. citri) into areas of the

United States.

The regulations contained in ``Subpart-Nursery Stock, Plants,

Roots, Bulbs, Seeds, and Other Plant Products,'' Sec. Sec. 319.37 through 319.37-14 (referred to below as the regulations), restrict, among other things, the importation of seeds for propagation. In this interim rule, we are amending the regulations to prohibit the importation of propagative seed of several Rutaceae genera from certain countries where citrus greening or citrus variegated chlorosis (CVC) is present. We are also requiring propagative seed of these genera imported from all other countries to be accompanied by a phytosanitary certificate with an additional

Page 17290

declaration that neither citrus greening nor CVC are known to occur in the country where the seed was produced. Finally, we are requiring propagative seed of genera that are hosts of citrus greening, but not of CVC, imported from a country in which CVC, but not citrus greening, is known to occur to be accompanied by a phytosanitary certificate with an additional declaration that citrus greening is not known to occur in the country where the seed was produced.

Citrus greening, also known as Huanglongbing disease of citrus, is considered to be one of the most serious citrus diseases in the world.

Citrus greening is a bacterial disease caused by strains of the bacterial pathogens ``Candidatus Liberibacter asiaticus'', ``Candidatus

Liberibacter africanus'', and ``Candidatus Liberibacter americanus'' that attack the vascular system of host plants. The pathogens are phloem-limited, inhabiting the food-conducting tissue of the host plant, and causes yellow shoots, blotchy mottling and chlorosis, reduced foliage, and tip dieback of citrus plants. Citrus greening greatly reduces production, destroys the economic value of the fruit, and can kill trees. Once a tree is infected, there is no cure for citrus greening. In areas of the world where the disease is endemic, citrus trees decline and die within a few years and may never produce usable fruit. Citrus greening was first detected in the United States in Miami-Dade County, FL, in 2005, and is only known to be present in the United States in the States of Florida and Georgia, Puerto Rico, two parishes in Louisiana, and two counties in South Carolina. We discuss the actions that APHIS has taken to date in response to the presence of citrus greening in the United States later in this document.

CVC is also a highly injurious disease of citrus. Caused by a strain of the bacterium Xylella fastidiosa, CVC causes severe chlorosis between veins on the leaves of affected plants. Leaves on affected plants frequently have discoloration of the upper leaf coupled with brown lesions underneath. CVC may reduce plant growth and lead to abnormal flowering and fruit production. CVC is currently not known to occur in the United States.

The introduction of CVC into the United States could result in substantial economic losses. In 2000, the estimated damage caused by

CVC in the State of S[atilde]o Paolo, Brazil, the site of the initial outbreak of CVC within the country and the State in which the disease is most prevalent, was approximately $129 million (considering the loss of plants in terminal stages, decrease in production, and disease control costs).\1\ Since that time, CVC has continued to cause major losses to citrus production throughout Brazil; these losses have exceeded several million dollars per year.\2\

Emerging evidence suggests that propagative seed of genera that are hosts of citrus greening or CVC can transmit these diseases. First, when seedlings are generated from seed that is taken from plants infected with citrus greening, a small percentage of those seedlings have been found to be infected with citrus greening.\3\ Similarly, evidence has suggested that CVC may infect propagative seeds, and cause extensive damage to seed embryos. Moreover, seedlings grown from CVC- infected seed have been shown to transmit CVC experimentally.\4\ This is important because the use of seedlings as rootstocks is the standard industry practice for the production of citrus trees, and both disease organisms can be present in infected plants without any visible signs or symptoms for several months or years. Therefore, infected seedlings could go undetected and serve as potential pathways for the diseases for an extended time.

The Animal and Plant Health Inspection Service (APHIS) of the U.S.

Department of Agriculture (USDA) has undertaken measures to control the artificial spread of citrus greening within the United States since its introduction in 2005. The most recent of these are a January 2008

Federal Domestic Quarantine Order that quarantined the entire State of

Florida for citrus greening, a June 2008 Federal Domestic Quarantine

Order that designated Orleans Parish, LA, as a quarantined area, an

October 2008 Federal Domestic Quarantine Order that designated

Washington Parish, LA, as a quarantined area, a July 2009 Federal

Domestic Quarantine Order that designated the State of Georgia and

Beaufort and Charleston Counties, SC, as quarantined areas, and a

December 2009 Federal Domestic Quarantine Order designating Puerto Rico as a quarantined area.\5\ Host articles, including propagative seed, produced within areas quarantined for citrus greening may only be moved interstate if destined for immediate export.

\5\ To view these Federal Orders, go to (http:// www.aphis.usda.gov/plant_health/plant_pest_info/citrus_greening/ regs.shtml). APHIS is currently undertaking rulemaking to codify these Federal Orders.

APHIS has also taken actions to prevent the introduction or dissemination of citrus greening and CVC into or within the United

States via the importation of propagative seed. On January 29, 2008,

APHIS issued a Federal Import Quarantine Order that prohibited the importation of propagative seeds from certain genera in the family

Rutaceae known to be hosts of citrus greening and/or CVC from countries in which one or both of these diseases are known to occur. The Federal

Import Quarantine Order also required propagative seeds of known hosts of citrus greening and/or CVC from countries considered free of these diseases to be accompanied at the time of arrival at the first port of entry in the United States by an import permit and a phytosanitary certificate with an additional declaration that the country where the propagative seed was produced is free of citrus greening and CVC.

On October 6, 2009, we updated the Federal Import Quarantine Order to prohibit the importation of seed of hosts of citrus greening from

Belize, Cuba, the Dominican Republic, and Mexico, following the detection of citrus greening in those countries. This interim rule amends the regulations to reflect the action taken by APHIS via its

Federal Import Quarantine Orders. In addition, based on the detection of citrus greening in Argentina and Jamaica after the October 6, 2009,

Federal Import Quarantine Order was issued, we are prohibiting the importation of seed of host genera of citrus greening from those countries, as well.\6\

\6\ We are also modifying the October 2009 Federal Order to consider seed of the genera Toddalia to be distinct from that of the genera Vepris. Emerging evidence suggests that the two genera sometimes have differing genetic histories.

Nursery stock, plants, and other propagative plant material that can be inspected, treated, or handled to prevent them from spreading plant pests are designated in the regulations as restricted articles.

Section 319.37-5 lists restricted articles that may be imported into the United States only if the

Page 17291

phytosanitary certificate required by Sec. 319.37-4 of the regulations contains an additional declaration that the restricted articles are free of specified plant pests or have been produced in accordance with certain requirements.

We are amending Sec. 319.37-5 by adding a new paragraph (w) that specifies that seed of the genera Aeglopsis, Atalantia, Balsamocitrus,

Bergera, Calodendrum, Citrofortunella, xCitroncirus, Citrus, Clausena,

Fortunella, Limonia, Microcitrus, Murraya, Poncirus, Severinia,

Swinglea, Toddalia, Triphasia, and Vepris from Argentina, Bangladesh,

Belize, Bhutan, Brazil, Burundi, Cambodia, Cameroon, Central African

Republic, China, Comoros, Cuba, the Dominican Republic, Ethiopia,

Eritrea, India, Indonesia, Jamaica, Japan, Kenya, Laos, Madagascar,

Malawi, Malaysia, Mauritius, Mexico, Myanmar, Nepal, Pakistan, Papua

New Guinea, Philippines, R[eacute]union, Rwanda, Saint Helena, Saudi

Arabia, Somalia, South Africa, Sri Lanka, Swaziland, Taiwan, Tanzania,

Thailand, Timor-Leste, Vietnam, Yemen, and Zimbabwe is prohibited importation into the United States. The paragraph also states that, except for the countries listed in paragraph (x) of the section

(discussed immediately below), seed of these genera from all other countries may be imported into the United States only if the phytosanitary certificate required by Sec. 319.37-4 contains an additional declaration that neither citrus greening nor CVC is known to occur in the country where the seed was produced.

All the genera listed in the previous paragraph are known to be hosts of citrus greening, citrus greening is known to exist in all the listed countries, and both citrus greening and CVC are known to exist in Argentina and Brazil. Some citrus species have been shown to be hosts of CVC, and no citrus species has been determined to be immune to

CVC. Accordingly, the available scientific evidence has led us to conclude that all Citrus species should also be considered hosts of

CVC, which is why we have included the requirement for an additional declaration regarding CVC.

Citrus greening is not known to exist in Costa Rica and Paraguay, but CVC is. Therefore, we are prohibiting the importation of seeds of hosts of CVC from those two countries into the United States; seeds that are hosts of citrus greening, but not of CVC, are not prohibited.

However, as a risk mitigation measure and in order to establish consistency between our importation requirements for seed from these two countries and our requirements for other countries in which citrus greening is not known to occur, we are adding a new paragraph (x) to

Sec. 319.37-5 that states that seed of the genus Citrus from Costa

Rica and Paraguay is prohibited importation into the United States, but that seed of the genera Aeglopsis, Atalantia, Balsamocitrus, Bergera,

Calodendrum, Citrofortunella, xCitroncirus, Clausena, Fortunella,

Limonia, Microcitrus, Murraya, Poncirus, Severinia, Swinglea, Toddalia,

Triphasia, and Vepris from these two countries may be imported into the

United States only if the phytosanitary certificate required by Sec. 319.37-4 contains an additional declaration that citrus greening is not known to occur in the country where the seed was produced.

All seed of the family Rutaceae that is shipped to the United

States from countries other than the countries listed earlier is a potential pathway for the introduction of citrus greening or CVC.

Accordingly, we are also amending the table in Sec. 319.37-2(a), which lists prohibited articles, or nursery stock, plants, and other propagative material that cannot feasibly be inspected, treated, or handled in a manner that assures us that the articles will not introduce plant pests new to or not known to be widely distributed in the United States. As amended, Sec. 319.37-2(a) prohibits seed of

Aeglopsis, Atalantia, Balsamocitrus, Bergera, Calodendrum,

Citrofortunella, Citrus, xCitroncirus, Clausena, Fortunella, Limonia,

Microcitrus, Murraya, Poncirus, Severinia, Swinglea, Toddalia,

Triphasia, and Vepris spp. from all countries from being imported into the United States, unless it meets the conditions for importation in

Sec. 319.37-5(w) or (x).

Section 319.37-6 lists treatment and other requirements under which seeds of certain genera and species may be imported into the United

States from countries and localities in which a plant pest is known to be present. This section currently requires seeds of all Rutaceae genera that are imported into the United States from countries in which citrus canker is known to occur to be treated for this disease.

However, Rutaceae species are known to be hosts not only of citrus canker, but also of citrus greening and CVC. Moreover, the countries listed in this section as being affected with citrus canker are also, in certain instances, countries in which citrus greening or CVC is known to occur. Therefore, we are amending this section to clarify that it applies only to countries where citrus canker, but not citrus greening or CVC, is known to exist. Specifically, we are removing any country from the list of countries from which Rutaceae seed may be imported with treatment if it is also listed in the table in Sec. 319.37-2(a) as a country in which either citrus greening or CVC is known to exist.

(Please note: As amended, Sec. 319.37-6 will still allow seed of

Rutaceae genera to be imported into the United States from certain countries in which citrus canker is known to exist following treatment, but the importation of all other plant parts of Rutaceae genera from those countries, other than fruit, is prohibited under Sec. 319.19.)

Finally, we are updating the botanical name of citrus canker in

Sec. 319.37-6. The name that has been used in the regulations,

Xanthomonas axonopodis, pv. citri, is no longer used by the international taxonomic community. Accordingly, we are amending the regulations in Sec. 319.37-6 to reflect the current nomenclature,

Xanthomonas citri subsp. citri.

Federal Preemption

On May 20, 2009, the President issued a memorandum to the heads of executive departments and agencies on the subject of preemption. The memorandum states that it is the general policy of the Administration that preemption of State law by executive departments and agencies should be undertaken only with full consideration of the legitimate prerogatives of the States and with a sufficient legal basis for preemption. The memorandum further states:

To ensure that executive departments and agencies include statements of preemption in regulations only when such statements have a sufficient legal basis:

Heads of departments and agencies should not include in regulatory preambles statements that the department or agency intends to preempt State law through the regulation except where preemption provisions are also included in the codified regulation.

Heads of departments and agencies should not include preemption provisions in codified regulations except where such provisions would be justified under legal principles governing preemption, including the principles outlined in Executive Order 13132.

Since 1996, Executive Order 12988, ``Civil Justice Reform,'' has required agencies to include in each regulation a statement regarding its preemptive effects in regulatory preambles under the heading,

``Executive Order 12988.''

In compliance with the May 2009 memorandum from the White House,

Page 17292

we are adding preemption provisions to part 319 that would apply to this rule, as well as to the existing regulations in part 319. Part 319 contains regulations that prohibit or restrict the importation of certain plants and plant products to prevent the introduction or dissemination of plant pests and noxious weeds into the United States.

Under section 436 of the Plant Protection Act (7 U.S.C. 7756), a

State or political subdivision of a State may not regulate in foreign commerce any plant or plant product in order to control, eradicate, or prevent the introduction or dissemination of a biological control organism, plant pest, or noxious weed within the United States.

Therefore, in accordance with section 436 of the Plant Protection

Act, the regulations in part 319 preempt all State and local laws and regulations that are inconsistent with or exceed the regulations in part 319.

Accordingly, in this interim rule, we are adding a new subpart,

``Preemption,'' (Sec. 319.1), to codify the preemptive effect of the regulations in part 319.

Immediate Action

Immediate action is necessary to amend the regulations to reflect the provisions of the October 6, 2009, Federal Import Quarantine Order issued to prevent the introduction or dissemination of citrus greening and CVC into or within the United States. Under these circumstances, the Administrator has determined that prior notice and opportunity for public comment are contrary to the public interest and that there is good cause under 5 U.S.C. 553 for making this action effective less than 30 days after publication in the Federal Register.

We will consider comments we receive during the comment period for this interim rule (see DATES above). After the comment period closes, we will publish another document in the Federal Register. The document will include a discussion of any comments we receive and any amendments we are making to the rule.

Executive Order 12866 and Regulatory Flexibility Act

This interim rule has been determined to be not significant for the purposes of Executive Order 12866 and, therefore, has not been reviewed by the Office of Management and Budget.

We have prepared an initial regulatory flexibility analysis for this action. The analysis identifies nursery operations producing citrus nursery stock for field planting as the small entities most likely to be affected by this action and considers the losses that may occur due to prohibitions on the importation of propagative seed from countries where citrus greening or CVC is known to occur. Based on the information presented in the analysis, we expect that these operations are unlikely to be dependent on seed of those genera, but lack information regarding their size distribution. We invite comment on our initial regulatory flexibility analysis, which is posted with this interim rule on the Regulations.gov Web site (see ADDRESSES above for instructions for accessing Regulations.gov) and may be obtained from the person listed under FOR FURTHER INFORMATION CONTACT.

Executive Order 12988

This rule has been reviewed under Executive Order 12988, Civil

Justice Reform. This rule: (1) Preempts all State and local laws and regulations that are inconsistent with this rule; (2) has no retroactive effect; and (3) does not require administrative proceedings before parties may file suit in court challenging this rule.

Paperwork Reduction Act

In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), the information collection or recordkeeping requirements included in this rule have been approved by the Office of Management and Budget (OMB) under OMB control number 0579-0049.

E-Government Act Compliance

The Animal and Plant Health Inspection Service is committed to compliance with the E-Government Act to promote the use of the Internet and other information technologies, to provide increased opportunities for citizen access to Government information and services, and for other purposes. For information pertinent to E-Government Act compliance related to this rule, please contact Mrs. Celeste Sickles,
