SUPPLEMENTARY INFORMATION: Background The regulations in 9 CFR part 93 (referred to below as the regulations) prohibit or restrict the importation of certain animals into the United States to prevent the introduction of communicable diseases of livestock. Subpart C—Horses, §§ 93.300 through 93.326, pertains to the importation of horses into the United States. Sections 93.301 and 93.304 of the regulations contain specific provisions for the importation of horses from regions affected with contagious equine metritis (CEM), which is a highly contagious venereal disease of horses and other equines caused by an infection with the bacterium Taylorella equigenitalis. The regulations provide that some types of horses may be imported from CEM-affected regions without restriction. For instance, weanlings and yearlings are exempt under § 93.301(c)(2)(iii). Other horses are allowed to be imported from CEMaffected regions provided they meet certain requirements that include quarantine, testing, and treatment as provided under § 93.301(d), (e), and (f). PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 Horses that fall under this category include Spanish Pure Breed horses from Spain; racing thoroughbreds from Germany, France, Ireland, and the United Kingdom; stallions and mares over 731 days of age; and horses that are imported under special provisions for temporary importation for competition or entertainment purposes. Approximately 2,500 horses imported from CEM-affected regions undergo CEM quarantine in the United States each year. Over the past 10 years, despite current requirements for preimport CEM testing in the country of origin, more than 28 CEM-positive horses have been identified during quarantine in the United States. In 2006, a private veterinarian in the United States detected a T. equigenitalis infection during a routine breeding soundness exam of an imported stallion that had been released from CEM quarantine in 2004 after testing negative for CEM. The epidemiological investigation that followed detected two other infected stallions on the same premises. This incident jeopardized the CEM-free status of the United States and had a significant impact on U.S. horse exports. In 2007, in response to this incident, APHIS’ Veterinary Services program initiated a review and assessment by Federal, State, and industry officials of U.S. equine import activities to identify any improvements to testing procedures that may be necessary to better mitigate the risk of a CEM-positive horse being released into the U.S. equine population. A second incident indicating a need to strengthen the CEM regulations occurred in April 2008 when an imported mare undergoing CEM quarantine demonstrated positive results for CEM on a complementfixation (CF) test, which has not been required for imported mares under the regulations; the required sampling of the clitoral sinuses and clitoral fossa of the mare had shown negative results for T. equigenitalis. The attending veterinarian administered the CF test because she knew about the recommendations that followed from the review and assessment of the 2006 incident. In December 2008, a U.S. origin stallion with no history of residence in a CEM-affected region was undergoing routine testing for semen export, and cultured positive for CEM. APHIS initiated an epidemiologic investigation E:\FR\FM\25MRR1.SGM 25MRR1 16684 Federal Register / Vol. 76, No. 58 / Friday, March 25, 2011 / Rules and Regulations to identify other potentially infected horses. Ultimately 23 stallions and 5 mares were identified as infected. An additional 250 stallions and 718 mares were identified as exposed to positive horses. All infected or exposed horses required culturing and treatment at their owners’ expense. The suspected source of the outbreak was a stallion imported from Denmark in late 2000 whose CEM infection was not detected on import testing. Because of the outbreak, some countries no longer recognized the United States as CEM-free and consequently placed restrictions on U.S. equine exports. The 2006 and 2008 incidents indicate that the regulations that have been in place are inadequate to identify all imported horses infected with T. equigenitalis. Given the incidents noted above, we have determined that the following regulatory changes are necessary and need to be implemented immediately in order to prevent the potential introduction and spread of CEM in the United States. erowe on DSK5CLS3C1PROD with RULES Exemption for Weanlings and Yearlings The regulations in § 93.301(c)(2)(iii) have exempted weanlings or yearlings (defined as not more than 731 days of age) from CEM quarantine requirements when their age is certified on the import health certificate required under § 93.314(a). The regulations have provided for this exemption because horses less than 2 years old have generally been considered too young to breed and therefore pose only a minimal risk of entering the United States with a venereal disease such as CEM. However, this assumption is now in question because APHIS has identified imported mares 731 days or less of age that were pregnant and therefore at risk of CEM infection. While retaining the current certification-of-age requirement, we are limiting the exemption from CEMrelated restrictions to weanlings and yearlings that have never been bred, and we are requiring that their breeding status be certified on the import health certificate required under § 93.314(a). This change to the regulations provides an additional safeguard against the spread of CEM to the U.S. horse population. Imported Stallions Because stallions do not show clinical signs of CEM after becoming exposed to the bacterium T. equigenitalis, diagnosis of CEM cannot be based on clinical signs alone. Furthermore, culture tests do not always detect T. equigenitalis. The stallion can look normal and test negative for T. equigenitalis, but still VerDate Mar<15>2010 14:52 Mar 24, 2011 Jkt 223001 infect the mare to which it is bred naturally or by artificial insemination. Therefore, the regulations under § 93.301(e) provide that stallions over 731 days of age from CEM-affected regions are to be bred to two test mares. Specifically, the regulations in paragraph (e)(3)(i) have stated that upon arrival at a CEM facility in an approved State, a set of specimens must be taken from a stallion’s prepuce, urethral sinus, and fossa glandis, and that after negative culture results have been obtained, the stallion must be test bred to two test mares. After being test bred, a stallion that cultured negative prior to being test bred has not been required to undergo another culture to test for T. equigenitalis unless a test mare tested positive for CEM, in which case the stallion would be treated for CEM and the testing process begun again. We are amending paragraph (e)(3)(i) of § 93.301 to require a fourth specimen to be taken from the stallion’s distal urethra and to increase the number of required sets of specimens (a set consists of one culture swab from each location) from imported stallions from one set to three sets at each of the four sites, all taken within a 12-day period with a minimum of 72 hours between each set. At least two of the three sets of specimens must be collected from the stallion, with negative results, before the stallion is bred to two test mares. If the test mares test negative for CEM after breeding, and if all of the stallion’s culture specimens test negative for CEM, then the stallion will be released from quarantine. These changes to the regulations will increase the likelihood of detecting T. equigenitalis in imported stallions, thereby reducing the risk that imported stallions will be released from quarantine with undiagnosed CEM infections. Test Mares Test mares are mares used to test stallions for CEM. To qualify to become a test mare, each mare must test negative for CEM as provided under § 93.301(e)(4). The regulations in § 93.301(e)(3)(i)(B) have required that the mucosal surfaces of the clitoral sinuses and clitoral fossa of a test mare must be cultured for T. equigenitalis on the third, sixth, and ninth days after breeding with an imported stallion in CEM quarantine. To increase the likelihood of detecting CEM in test mares, we are amending the regulations to require that either the distal cervix or endometrium be cultured for CEM in addition to the clitoral sinuses and clitoral fossa. We are also extending the allowable timeframe in (e)(4)(ii) to PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 complete all three culture sets from the current 7-day period to a 12-day period, with specimens collected anytime between the third and the fourteenth day after breeding, with a minimum of 72 hours between each set. The additional time allowed to collect all culture samplings was added at the request of the veterinarians, because the 7-day timeframe did not allow any flexibility in scheduling, since samples generally could not be shipped or processed on weekends. Extending the timeframe from 7 days to 12 days to account for the laboratory’s hours of operations will help decrease testing delays caused by unusable samples. Furthermore, the regulations in paragraph (e)(3)(i)(B) have required the blood sample for the required CF test to be drawn from the test mare on the fifteenth day after breeding. We are amending the paragraph to require that a test mare’s blood be drawn for a CF test on the twenty-first day after breeding. This amendment aligns our requirements with the World Organization for Animal Health’s (OIE) Manual of Diagnostic Tests,1 which recommends screening mares between 21 and 45 days after breeding. Imported Mares Once an imported mare has arrived at a CEM quarantine facility in an approved State, the regulations in § 93.301(e)(5)(i) have required specimens to be collected from the mucosal surfaces of the clitoral sinuses and clitoral fossa on days 1, 4, and 7 during a 7-day period with all culture sets received by an approved laboratory within 48 hours of collection. To increase the likelihood of detecting CEM in these imported mares, we are adding a requirement, as we are doing for test mares, to collect specimens from either the distal cervix or the endometrium in nonpregnant mares in addition to the specimens taken from the mucosal surfaces of the clitoral sinuses and clitoral fossa. To help avoid test delays and unusable samples due to facility and laboratory hours of operations, we are extending the timeframe to complete sampling from the current 7-day period to a 12-day period with no less than 72 hours between each set. In addition, we are now requiring that an imported mare be given a CF test upon arrival at a State’s CEM quarantine facility. CF testing will allow identification of antibodies from any recent exposure to CEM and provide 1 To view the OIE Terrestrial Animal Health Code, go to https://www.oie.int/eng/normes/mcode/ en_sommaire.htm.

Spanish Pure Breed Horses and Thoroughbred Horses; Horses Temporarily Imported for Competition or Entertainment Purposes To reflect the changes discussed above, we are amending paragraph (d)(1)(ii)(D) in § 93.301 to require that Spanish Pure Breed horses from Spain and thoroughbred horses over 731 days of age from France, Germany, Ireland, and the United Kingdom, test negative for CEM based on the culturing of three sets of specimens. For female horses, the specimens must be collected from the mucosal surfaces of the clitoral fossa, distal cervix or endometrium, and the clitoral sinuses; for any male horses, the specimens must be collected from the surfaces of the prepuce, the urethral sinus, the distal urethra, and the fossa glandis, including the diverticulum of the fossa glandis. For both female and male horses, the sets of specimens must be collected on three separate occasions within a 12-day period with no less than 72 hours between each set, and the last of these sets of specimens must be collected within 30 days prior to the exportation of the horses to the United States. All specimens must be collected by a licensed veterinarian who either is, or is acting in the presence of, the veterinarian signing the required health certificate. We are making similar changes to paragraph (f)(3) in § 93.301, which contains special provisions for temporary importation of horses for competition or entertainment purposes. Specifically, we will require that such horses be accompanied by a health certificate that certifies that cultures negative for CEM were obtained from three sets of specimens. For female horses, the specimens must be collected from the mucosal surfaces of the clitoral fossa and clitoral sinuses, with one set of specimens including a specimen from the surfaces of the distal cervix or endometrium; for male horses, the specimens must be collected from the surfaces of the prepuce, the urethral sinus, the distal urethra, and the fossa glandis, including the diverticulum of the fossa glandis. For both female and male horses, the sets of specimens must be collected on three separate occasions within a 12-day period with no less than 72 hours between each set, and the last of these sets of specimens must be collected within 30 days prior to the exportation of horses to the United States. All specimens must be collected by a licensed veterinarian who either is, or is acting in the presence of, the veterinarian signing the certificate. VerDate Mar<15>2010 14:52 Mar 24, 2011 Jkt 223001 These changes, which represent an increase in the number of specimens that must be collected, are consistent with the changes we are making for other mares and stallions being imported from CEM-affected regions to the United States and will provide additional safeguards against the spread of CEM to the U.S. horse population. Emergency Action This rulemaking is necessary on an emergency basis to prevent the introduction and spread of CEM into the equine population of 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 rule 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. 16685 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 in conflict 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.

Accordingly, we are amending 9 CFR part 93 as follows: PART 93—IMPORTATION OF CERTAIN ANIMALS, BIRDS, FISH, AND POULTRY, AND CERTAIN ANIMAL, BIRD, AND POULTRY PROUDUCTS; REQUIREMENTS FOR MEANS OF CONVEYANCE AND SHIPPING CONTAINERS 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 U.S. importers of mares and stallions from CEM countries as the small entities most likely to be affected by this action and considers the costs associated with complying with new requirements. Based on the information presented in the analysis, we expect that U.S. importers will experience a slight increase in quarantine and treatment costs as a result of this action. The overall impact of the additional costs for the horse industry is not expected to be significant, given the relatively small number of horses imported from CEM countries.

SUPPLEMENTARY INFORMATION:

Background

    The regulations in 9 CFR part 93 (referred to below as the 
regulations) prohibit or restrict the importation of certain animals 
into the United States to prevent the introduction of communicable 
diseases of livestock. Subpart C--Horses, Sec. Sec.  93.300 through 
93.326, pertains to the importation of horses into the United States. 
Sections 93.301 and 93.304 of the regulations contain specific 
provisions for the importation of horses from regions affected with 
contagious equine metritis (CEM), which is a highly contagious venereal 
disease of horses and other equines caused by an infection with the 
bacterium Taylorella equigenitalis.
    The regulations provide that some types of horses may be imported 
from CEM-affected regions without restriction. For instance, weanlings 
and yearlings are exempt under Sec.  93.301(c)(2)(iii). Other horses 
are allowed to be imported from CEM-affected regions provided they meet 
certain requirements that include quarantine, testing, and treatment as 
provided under Sec.  93.301(d), (e), and (f). Horses that fall under 
this category include Spanish Pure Breed horses from Spain; racing 
thoroughbreds from Germany, France, Ireland, and the United Kingdom; 
stallions and mares over 731 days of age; and horses that are imported 
under special provisions for temporary importation for competition or 
entertainment purposes.
    Approximately 2,500 horses imported from CEM-affected regions 
undergo CEM quarantine in the United States each year. Over the past 10 
years, despite current requirements for pre-import CEM testing in the 
country of origin, more than 28 CEM-positive horses have been 
identified during quarantine in the United States.
    In 2006, a private veterinarian in the United States detected a T. 
equigenitalis infection during a routine breeding soundness exam of an 
imported stallion that had been released from CEM quarantine in 2004 
after testing negative for CEM. The epidemiological investigation that 
followed detected two other infected stallions on the same premises. 
This incident jeopardized the CEM-free status of the United States and 
had a significant impact on U.S. horse exports. In 2007, in response to 
this incident, APHIS' Veterinary Services program initiated a review 
and assessment by Federal, State, and industry officials of U.S. equine 
import activities to identify any improvements to testing procedures 
that may be necessary to better mitigate the risk of a CEM-positive 
horse being released into the U.S. equine population.
    A second incident indicating a need to strengthen the CEM 
regulations occurred in April 2008 when an imported mare undergoing CEM 
quarantine demonstrated positive results for CEM on a complement-
fixation (CF) test, which has not been required for imported mares 
under the regulations; the required sampling of the clitoral sinuses 
and clitoral fossa of the mare had shown negative results for T. 
equigenitalis. The attending veterinarian administered the CF test 
because she knew about the recommendations that followed from the 
review and assessment of the 2006 incident.
    In December 2008, a U.S. origin stallion with no history of 
residence in a CEM-affected region was undergoing routine testing for 
semen export, and cultured positive for CEM. APHIS initiated an 
epidemiologic investigation

[[Page 16684]]

to identify other potentially infected horses. Ultimately 23 stallions 
and 5 mares were identified as infected. An additional 250 stallions 
and 718 mares were identified as exposed to positive horses. All 
infected or exposed horses required culturing and treatment at their 
owners' expense. The suspected source of the outbreak was a stallion 
imported from Denmark in late 2000 whose CEM infection was not detected 
on import testing. Because of the outbreak, some countries no longer 
recognized the United States as CEM-free and consequently placed 
restrictions on U.S. equine exports. The 2006 and 2008 incidents 
indicate that the regulations that have been in place are inadequate to 
identify all imported horses infected with T. equigenitalis.
    Given the incidents noted above, we have determined that the 
following regulatory changes are necessary and need to be implemented 
immediately in order to prevent the potential introduction and spread 
of CEM in the United States.

Exemption for Weanlings and Yearlings

    The regulations in Sec.  93.301(c)(2)(iii) have exempted weanlings 
or yearlings (defined as not more than 731 days of age) from CEM 
quarantine requirements when their age is certified on the import 
health certificate required under Sec.  93.314(a). The regulations have 
provided for this exemption because horses less than 2 years old have 
generally been considered too young to breed and therefore pose only a 
minimal risk of entering the United States with a venereal disease such 
as CEM. However, this assumption is now in question because APHIS has 
identified imported mares 731 days or less of age that were pregnant 
and therefore at risk of CEM infection.
    While retaining the current certification-of-age requirement, we 
are limiting the exemption from CEM-related restrictions to weanlings 
and yearlings that have never been bred, and we are requiring that 
their breeding status be certified on the import health certificate 
required under Sec.  93.314(a). This change to the regulations provides 
an additional safeguard against the spread of CEM to the U.S. horse 
population.

Imported Stallions

    Because stallions do not show clinical signs of CEM after becoming 
exposed to the bacterium T. equigenitalis, diagnosis of CEM cannot be 
based on clinical signs alone. Furthermore, culture tests do not always 
detect T. equigenitalis. The stallion can look normal and test negative 
for T. equigenitalis, but still infect the mare to which it is bred 
naturally or by artificial insemination. Therefore, the regulations 
under Sec.  93.301(e) provide that stallions over 731 days of age from 
CEM-affected regions are to be bred to two test mares.
    Specifically, the regulations in paragraph (e)(3)(i) have stated 
that upon arrival at a CEM facility in an approved State, a set of 
specimens must be taken from a stallion's prepuce, urethral sinus, and 
fossa glandis, and that after negative culture results have been 
obtained, the stallion must be test bred to two test mares. After being 
test bred, a stallion that cultured negative prior to being test bred 
has not been required to undergo another culture to test for T. 
equigenitalis unless a test mare tested positive for CEM, in which case 
the stallion would be treated for CEM and the testing process begun 
again.
    We are amending paragraph (e)(3)(i) of Sec.  93.301 to require a 
fourth specimen to be taken from the stallion's distal urethra and to 
increase the number of required sets of specimens (a set consists of 
one culture swab from each location) from imported stallions from one 
set to three sets at each of the four sites, all taken within a 12-day 
period with a minimum of 72 hours between each set. At least two of the 
three sets of specimens must be collected from the stallion, with 
negative results, before the stallion is bred to two test mares. If the 
test mares test negative for CEM after breeding, and if all of the 
stallion's culture specimens test negative for CEM, then the stallion 
will be released from quarantine.
    These changes to the regulations will increase the likelihood of 
detecting T. equigenitalis in imported stallions, thereby reducing the 
risk that imported stallions will be released from quarantine with 
undiagnosed CEM infections.

Test Mares

    Test mares are mares used to test stallions for CEM. To qualify to 
become a test mare, each mare must test negative for CEM as provided 
under Sec.  93.301(e)(4). The regulations in Sec.  93.301(e)(3)(i)(B) 
have required that the mucosal surfaces of the clitoral sinuses and 
clitoral fossa of a test mare must be cultured for T. equigenitalis on 
the third, sixth, and ninth days after breeding with an imported 
stallion in CEM quarantine. To increase the likelihood of detecting CEM 
in test mares, we are amending the regulations to require that either 
the distal cervix or endometrium be cultured for CEM in addition to the 
clitoral sinuses and clitoral fossa. We are also extending the 
allowable timeframe in (e)(4)(ii) to complete all three culture sets 
from the current 7-day period to a 12-day period, with specimens 
collected anytime between the third and the fourteenth day after 
breeding, with a minimum of 72 hours between each set. The additional 
time allowed to collect all culture samplings was added at the request 
of the veterinarians, because the 7-day timeframe did not allow any 
flexibility in scheduling, since samples generally could not be shipped 
or processed on weekends. Extending the timeframe from 7 days to 12 
days to account for the laboratory's hours of operations will help 
decrease testing delays caused by unusable samples.
    Furthermore, the regulations in paragraph (e)(3)(i)(B) have 
required the blood sample for the required CF test to be drawn from the 
test mare on the fifteenth day after breeding. We are amending the 
paragraph to require that a test mare's blood be drawn for a CF test on 
the twenty-first day after breeding. This amendment aligns our 
requirements with the World Organization for Animal Health's (OIE) 
Manual of Diagnostic Tests,\1\ which recommends screening mares between 
21 and 45 days after breeding.

Imported Mares

    Once an imported mare has arrived at a CEM quarantine facility in 
an approved State, the regulations in Sec.  93.301(e)(5)(i) have 
required specimens to be collected from the mucosal surfaces of the 
clitoral sinuses and clitoral fossa on days 1, 4, and 7 during a 7-day 
period with all culture sets received by an approved laboratory within 
48 hours of collection. To increase the likelihood of detecting CEM in 
these imported mares, we are adding a requirement, as we are doing for 
test mares, to collect specimens from either the distal cervix or the 
endometrium in nonpregnant mares in addition to the specimens taken 
from the mucosal surfaces of the clitoral sinuses and clitoral fossa. 
To help avoid test delays and unusable samples due to facility and 
laboratory hours of operations, we are extending the timeframe to 
complete sampling from the current 7-day period to a 12-day period with 
no less than 72 hours between each set.
    In addition, we are now requiring that an imported mare be given a 
CF test upon arrival at a State's CEM quarantine facility. CF testing 
will allow identification of antibodies from any recent exposure to CEM 
and provide

[[Page 16685]]

supplementary information concerning the mare's CEM status.

Spanish Pure Breed Horses and Thoroughbred Horses; Horses Temporarily 
Imported for Competition or Entertainment Purposes

    To reflect the changes discussed above, we are amending paragraph 
(d)(1)(ii)(D) in Sec.  93.301 to require that Spanish Pure Breed horses 
from Spain and thoroughbred horses over 731 days of age from France, 
Germany, Ireland, and the United Kingdom, test negative for CEM based 
on the culturing of three sets of specimens. For female horses, the 
specimens must be collected from the mucosal surfaces of the clitoral 
fossa, distal cervix or endometrium, and the clitoral sinuses; for any 
male horses, the specimens must be collected from the surfaces of the 
prepuce, the urethral sinus, the distal urethra, and the fossa glandis, 
including the diverticulum of the fossa glandis. For both female and 
male horses, the sets of specimens must be collected on three separate 
occasions within a 12-day period with no less than 72 hours between 
each set, and the last of these sets of specimens must be collected 
within 30 days prior to the exportation of the horses to the United 
States. All specimens must be collected by a licensed veterinarian who 
either is, or is acting in the presence of, the veterinarian signing 
the required health certificate.
    We are making similar changes to paragraph (f)(3) in Sec.  93.301, 
which contains special provisions for temporary importation of horses 
for competition or entertainment purposes. Specifically, we will 
require that such horses be accompanied by a health certificate that 
certifies that cultures negative for CEM were obtained from three sets 
of specimens. For female horses, the specimens must be collected from 
the mucosal surfaces of the clitoral fossa and clitoral sinuses, with 
one set of specimens including a specimen from the surfaces of the 
distal cervix or endometrium; for male horses, the specimens must be 
collected from the surfaces of the prepuce, the urethral sinus, the 
distal urethra, and the fossa glandis, including the diverticulum of 
the fossa glandis. For both female and male horses, the sets of 
specimens must be collected on three separate occasions within a 12-day 
period with no less than 72 hours between each set, and the last of 
these sets of specimens must be collected within 30 days prior to the 
exportation of horses to the United States. All specimens must be 
collected by a licensed veterinarian who either is, or is acting in the 
presence of, the veterinarian signing the certificate.
    These changes, which represent an increase in the number of 
specimens that must be collected, are consistent with the changes we 
are making for other mares and stallions being imported from CEM-
affected regions to the United States and will provide additional 
safeguards against the spread of CEM to the U.S. horse population.

Emergency Action

    This rulemaking is necessary on an emergency basis to prevent the 
introduction and spread of CEM into the equine population of 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 rule 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 U.S. importers of mares and 
stallions from CEM countries as the small entities most likely to be 
affected by this action and considers the costs associated with 
complying with new requirements. Based on the information presented in 
the analysis, we expect that U.S. importers will experience a slight 
increase in quarantine and treatment costs as a result of this action. 
The overall impact of the additional costs for the horse industry is 
not expected to be significant, given the relatively small number of 
horses imported from CEM countries.
    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 in conflict 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

    This interim rule contains no information collection or 
recordkeeping requirements under the Paperwork Reduction Act of 1995 
(44 U.S.C. 3501 et seq.).
