Abstract

We are amending the horse protection regulations to provide that the Animal and Plant Health Inspection Service will screen, train, and authorize qualified persons for appointment by the management of any horse show, horse exhibition, or horse sale or auction to detect and diagnose soring at such events for the purposes of enforcing the Horse Protection Act. These and other regulatory amendments will strengthen the Agency's efforts to protect horses from the cruel and inhumane practice of soring as the Act requires and by so doing eliminate unfair competition.

SUPPLEMENTARY INFORMATION:

Background

    Under the Horse Protection Act (HPA, or the Act, 15 U.S.C. 1821 et 
seq.), the Secretary of Agriculture is authorized to promulgate 
regulations to prohibit the movement, showing, exhibition, or sale of 
sore horses.
    The Secretary has delegated responsibility for administering the 
Act to the Administrator of the U.S. Department of Agriculture's (USDA) 
Animal and Plant Health Inspection Service (APHIS). Within APHIS, the 
responsibility for administering the Act has been delegated to the 
Deputy Administrator for Animal Care. Regulations and standards 
established under the Act are contained in 9 CFR part 11 (referred to 
below as the Horse Protection regulations or just the regulations), and 
9 CFR part 12 lists the rules of practice governing administrative 
proceedings.
    Section 2 of the Act, ``Definitions'' (15 U.S.C. 1821(3)), defines 
a ``sore'' horse as follows:
    ``The term `sore' when used to describe a horse means that:
    (A) An irritating or blistering agent has been applied, internally 
or externally, by a person to any limb of a horse,
    (B) Any burn, cut, or laceration has been inflicted by a person on 
any limb of a horse,
    (C) Any tack, nail, screw, or chemical agent has been injected by a 
person into or used by a person on any limb of a horse, or
    (D) Any other substance or device \1\ has been used by a person on 
any limb of a horse or a person has engaged in a practice involving a 
horse, and, as a result of such application, infliction, injection, 
use, or practice, such horse suffers, or can reasonably be expected to 
suffer, physical pain or distress, inflammation, or lameness when 
walking, trotting, or otherwise moving, except that such term does not 
include such an application, infliction, injection, use, or practice in 
connection with the therapeutic treatment of a horse by or under the 
supervision of a person licensed to practice veterinary medicine in the 
State in which such treatment was given.''
---------------------------------------------------------------------------

    \1\ We interpret ``device'' to include chains, which are 
commonly placed on the limbs of Performance division Tennessee 
Walking Horses and racking horses when competing in shows. The 
association of chains with devices has been included in the 
regulations since 1979: ``General Prohibitions'' (Sec.  11.2(a)) 
states that, notwithstanding the provisions of paragraph (b), ``. . 
. no chain, boot, roller, collar, action device, nor any other 
device . . . shall be used. . . .'' [our emphasis].
---------------------------------------------------------------------------

    Soring has been used almost exclusively in the training of certain 
Tennessee Walking Horses and racking horses \2\ to induce pain, 
resulting in an exaggerated gait that is valued in the show ring. 
However, the HPA's prohibition against sored horses participating in 
shows, exhibitions, sales, and auctions extends to events involving all 
horse breeds.\3\ In addition to declaring that the soring of horses is 
cruel and inhumane, Congress further found that the movement, showing, 
exhibition, or sale of sore horses in intrastate commerce adversely 
affects and burdens interstate and foreign commerce and creates unfair 
competition.
---------------------------------------------------------------------------

    \2\ The racking horse is a breed derived from the Tennessee 
Walking Horse. It has a smooth, natural gait known as the ``rack,'' 
a four-beat gait with only one foot striking the ground at a time.
    \3\ Records of non-compliance with the HPA's soring prohibition 
is rare in breeds other than the Tennessee Walking Horse and racking 
horse. APHIS nonetheless conducts occasional inspections and 
investigates other breed activity, and keeps records of any such 
noncompliance.
---------------------------------------------------------------------------

Background of HPA Regulations

    Under the HPA, it is unlawful for any person to show, exhibit, 
sell, or transport sore horses, or to use any prohibited equipment, 
device, paraphernalia, or substance in horse shows, exhibitions, sales, 
or auctions. The HPA holds horse owners responsible should they allow 
any such unlawful activities to occur, and requires management of horse 
shows, exhibitions, sales, and auctions (referred to as ``management'' 
or ``event management,'' below) to ensure that sore horses do not 
compete or otherwise participate in these events.
    After Congress passed the HPA in 1970, APHIS established 
regulations to enforce the Act, including restrictions on the use of 
certain equipment, devices, and substances. In accordance with the Act, 
the regulations also include inspection provisions for detecting soring 
in horses at shows, exhibitions, sales, and auctions. In 1976, Congress 
amended the Act \4\ to allow (but not require) the management of any 
horse show, exhibition, or sale or auction to appoint persons qualified 
to inspect horses for soreness. Section 4 (15 U.S.C 1823(c)) requires 
the Secretary of Agriculture to prescribe by regulation requirements 
for any appointment by the management of a horse show, exhibition, 
sale, or auction of persons qualified to detect and diagnose a horse 
which is sore or to otherwise inspect horses for the purpose of 
enforcing the Act. Although the Act does not require that management 
appoint a qualified person to inspect horses, if management chooses not 
to do so it can be held liable for violating the Act if it fails to 
disqualify a sore horse from participating in an event. If, 
alternatively, event management appoints a qualified person to conduct 
inspections, management may be held liable only for failing to 
disqualify a sore horse after being notified by the qualified person or 
by the Secretary of Agriculture, or his or her designee, that a horse 
is sore.
---------------------------------------------------------------------------

    \4\ Public Law 94-360, section 3, July 13, 1976, 90 Stat. 915; 
<a href="https://www.govinfo.gov/content/pkg/STATUTE-90/pdf/STATUTE-90-Pg915.pdf">https://www.govinfo.gov/content/pkg/STATUTE-90/pdf/STATUTE-90-Pg915.pdf</a>.
---------------------------------------------------------------------------

    Responding to Congress's 1976 amendment to the Act, APHIS revised 
the regulations (44 FR 1558-1566, January 5, 1979) to include 
qualifications for ``Designated Qualified Persons,'' or DQPs, to serve 
as third-party inspectors employed and compensated by the industry, as 
well as provisions for certifying industry-run

[[Page 39195]]

programs to train and license DQPs. Prior to this final rule, these 
training and licensing programs were administered by Horse Industry 
Organizations, or HIOs.
    HIOs have historically filled several roles, both unregulated and 
regulated, for horse shows, exhibitions, sales, and auctions. For 
example, event management sometimes retains an HIO to assist with 
activities not regulated under the Act, such as registering 
participants and coordinating event logistics, supplying show judges, 
and promoting events.\5\ Regulated HIO activities, in addition to 
training and licensing DQPs, included reporting disciplinary actions 
against exhibitors, event management, and DQPs to APHIS. Under the 
previous regulatory regime, an HIO seeking certification to train and 
license DQPs was required to submit to APHIS a formal request in 
writing for certification of its DQP program and a detailed outline of 
the program.
---------------------------------------------------------------------------

    \5\ HIOs may continue conducting such unregulated activities 
under the new regulatory scheme.
---------------------------------------------------------------------------

    Under the Horse Protection program prior to promulgation of this 
final rule, DQPs were the primary party responsible for inspecting and 
diagnosing soreness in horses participating in horse shows, 
exhibitions, auctions, or sales. A DQP was a qualified person who, 
under the provisions of 15 U.S.C 1823(c) cited above, could be 
appointed by management of a horse show or sale to detect horses that 
are sored, and to otherwise conduct inspections for the purpose of 
enforcing the Act. DQPs were reimbursed for services directly by event 
management or by an HIO contracting with the DQPs to provide 
inspections for events. DQPs were required to have equine experience 
and meet professional qualifications as set forth in the regulations.
    DQP candidates also had to successfully complete a formal training 
program developed and delivered by the HIO before they could be 
licensed, except that veterinarians already accredited by USDA were 
able to be licensed as DQPs without having to participate in formal 
training. Such veterinarians also had to be either a member of the 
American Association of Equine Practitioners, or a large animal 
practitioner with substantial equine experience, or be, based on the 
HIO's judgment, otherwise knowledgeable of equine lameness as related 
to soring and soring practices. The regulations provided that 
veterinarians having such knowledge might include those with a small 
animal practice who own, train, judge, or show horses, or who are 
Doctors of Veterinary Medicine who teach equine-related subjects in an 
accredited college or school of veterinary medicine.
    Alternatively, DQPs were able to be farriers, horse trainers, and 
other knowledgeable individuals whose past experience and training 
would, in the HIO's judgment, qualify them for positions as HIO 
stewards or judges (or their equivalent), provided that they were 
trained and licensed by an HIO or association whose DQP program was 
certified by APHIS.
    APHIS Veterinary Medical Officers (VMOs) would sometimes attend 
HPA-covered events unannounced to oversee and conduct inspections and 
to otherwise determine compliance with the Act. To ensure that horses 
are disqualified when soreness is detected or when other violations are 
found, APHIS also reviewed reports by event management, HIOs, and DQPs, 
and conducted audits of records maintained by certified DQP programs.
    APHIS has used several options for resolving a case in which the 
evidence substantiates that an alleged violation has occurred. These 
include issuing official warnings to those involved in the alleged 
violation, disqualification from competing, offering to resolve the 
case through a stipulated penalty, and referring the case to the USDA 
Office of the General Counsel for formal administrative action before 
the USDA Office of Administrative Law Judges or referral to the U.S. 
Department of Justice.
    As we explained in the proposal on which this final rule is based, 
this rule replaces a final rule that was filed for public inspection on 
the Federal Register website, in advance of official publication, on 
January 19, 2017. However, the incoming Administration at that time 
ordered this and other rules pending publication to be withdrawn, which 
USDA accordingly did. As the result of a lawsuit claiming that the rule 
had actually been promulgated and that USDA had withdrawn the 2017 
final rule without proper notice and comment as required under the 
Administrative Procedure Act, a notice of proposed rulemaking to 
withdraw the 2017 final rule legally was published in the Federal 
Register on July 21, 2023 (88 FR 47068-47071, Docket No. APHIS-2011-
0009), and finalized on October 31, 2023 (88 FR 74336-74341, Docket No. 
APHIS-2011-0009). This current rule incorporates provisions included in 
the 2017 HPA final rule to eliminate soring, including replacing DQPs 
with APHIS-authorized inspectors and banning pads and action devices on 
Tennessee Walking Horses and racking horses, the only two breeds in 
which APHIS currently finds elevated levels of soring.

Evaluations of the Horse Protection Program

    Since 2009, multiple evaluations have been conducted outside the 
Agency to determine program efficacy. In September 2010, USDA's Office 
of the Inspector General (OIG) formally evaluated APHIS' oversight of 
the Horse Protection program \6\ in accordance with generally accepted 
government auditing standards.\7\ USDA-OIG concluded that the 
inspection program, in which the horse industry trains and licenses 
DQPs to inspect horses under APHIS' oversight, is ineffective in 
ensuring that horses are not sore upon inspection as required under the 
Act.
---------------------------------------------------------------------------

September 2010. The document is available on the <a href="http://Regulations.gov">Regulations.gov</a> 
website (see under ADDRESSES in this document for a link to

---------------------------------------------------------------------------

    USDA-OIG's findings regarding the persistence of soring are 
consistent with those of the USDA's Office of the Judicial Officer 
(OJO), which issues final decisions on behalf of the Secretary of 
Agriculture for purposes of judicial review. The Secretary of 
Agriculture, through the OJO, has found that DQP inspections of horses 
are less probative than inspections conducted by APHIS VMOs. Decisions 
issued by the OJO include accounts of exhibitors showing sored horses 
that had been inspected and cleared by DQPs, cursory inspections or use 
of incorrect methods by DQPs, and exhibitors attempting to avoid 
violations by having another person acknowledge responsibility.
    In addition, a 2021 study \8\ by the National Academy of Sciences 
(NAS) analyzed the causes of soring and its diagnosis in light of the 
current regulations. This is the most recent available study on this 
subject. The NAS study concurs with the USDA-OIG audit report's 
recommendation that a regulatory change to the inspection component of 
the Horse Protection program is necessary to eliminate the conflicts of 
interest that encourage soring. The NAS committee authoring the study 
examined the inspection process, which included a review of 61

[[Page 39196]]

inspection videos provided by APHIS and by HIOs that revealed numerous 
instances of inadequate performance by DQPs.\9\ The NAS committee 
strongly recommended that the use of DQPs for inspections under the 
current regulations be discontinued and that only veterinarians, 
preferably with equine experience, be allowed to examine horses, as is 
done in other equine competitions. The committee added that if APHIS 
continues to use third-party inspectors, they should be limited to 
veterinarians or other equine industry professionals who are screened 
for potential industry conflicts of interest and trained by APHIS to 
properly inspect horses for soring. The committee also stated that 
consequences for performing substandard examinations should be strictly 
enforced, and that reports of substandard performance and enforcement 
warning letters should come from APHIS, not from HIOs.

---------------------------------------------------------------------------

    These evaluations, which were, again, external to APHIS, also 
correspond to evaluations of program efficacy that APHIS conducts as 
part of ongoing evaluation of its Horse Protection program. Inspection 
data compiled by APHIS from fiscal years (FY) 2017 to 2022 demonstrated 
that inconsistencies persisted in the number of violations detected by 
APHIS officials and those issued by DQPs inspecting horses. During this 
period, APHIS attended about 16 percent of all HPA-covered events 
featuring Tennessee Walking Horses, racking horses, and other breeds at 
which horse industry DQPs conducted inspections. These inspections were 
conducted on horses competing in the Performance (``padded'') division 
as well as the flat-shod division. While APHIS attended only a fraction 
of the events at which DQPs were appointed to inspect horses, APHIS 
consistently reported much higher rates of noncompliance at these 
events based on its VMO inspection findings when compared to DQP 
findings. Moreover, virtually all noncompliances were found in padded 
horses competing in the Performance division.

Proposed Rule

    In light of the foregoing evaluations, on August 21, 2023, we 
published in the Federal Register (88 FR 56924-56962, Docket No. APHIS-
2022-0004) a proposal \10\ to amend the Horse Protection regulations. 
Substantive changes we proposed to make in part 11 included:
---------------------------------------------------------------------------

    \10\ To view the proposal, supporting documents, and the 
comments we received, go to <a href="http://www.regulations.gov">www.regulations.gov</a> and enter APHIS-
2022-0004 in the Search field.
---------------------------------------------------------------------------

    <bullet> Removing the requirement that DQPs be trained and licensed 
by HIOs and removing the term DQPs from the regulations. Instead, we 
proposed that APHIS would screen and train qualified persons to be 
``Horse Protection Inspectors,'' or HPIs. APHIS would authorize these 
applicants, preferably licensed veterinarians, as HPIs after screening 
them for potential conflicts of interest and conducting training.
    <bullet> Removing all regulatory requirements pertaining to HIOs, 
as HIOs would no longer have any regulatory responsibilities specific 
to them. APHIS would assume program administration and development, HPI 
training, and HPI disciplinary actions as necessary to enforce the Act 
and regulations. We stated that other services contracted between HIOs 
and event management, such as supplying judges and handling show 
logistics, would not be affected.
    <bullet> Prohibiting any device, method, practice, or substance 
applied to any horse that can mask evidence of soring. (We stated that 
existing prohibitions on other items and practices that can reasonably 
be expected to cause or contribute to soring would be retained in the 
regulations.)
    <bullet> Prohibiting all action devices, artificial extension of 
toe length, pads, wedges, and lubricants \11\ on the limbs or feet of 
Tennessee Walking Horses and racking horses (with exceptions for 
approved therapeutic uses of artificial extension of toe length, pads, 
wedges, and substances). An action device is any boot, collar, chain, 
roller, beads, bangles, or other device which encircles or is placed 
upon the lower extremity of the leg of a horse in such a manner that it 
can either rotate around the leg, or slide up and down the leg so as to 
cause friction, or which can strike the hoof, coronet band, or fetlock 
joint. We proposed to afford the industry 270 days from the effective 
date of the final rule before the prohibition on pads and wedges, and 
artificial toe extensions, would be effective.
---------------------------------------------------------------------------

    \11\ All other substances are already prohibited on the on the 
extremities above the hoof of any Tennessee Walking Horse or racking 
horse while being shown, exhibited, or offered for sale at any horse 
show, horse exhibition, or horse sale or auction.
---------------------------------------------------------------------------

    <bullet> Replacing the ``scar rule'' \12\ with language that more 
accurately describes visible dermatologic changes indicative of soring, 
and removing the requirement that such changes be bilateral.
---------------------------------------------------------------------------

    \12\ In place of this term, we prefer to use ``Dermatologic 
conditions indicative of soring (DCIS),'' although we still use 
``scar rule'' in this document when referring to the current 
regulations or when a commenter refers to it as such.
---------------------------------------------------------------------------

    <bullet> Requiring the management of any horse show, exhibition, 
sale, or auction that elects to utilize an APHIS representative or HPI 
to choose and appoint an additional HPI if more than 100 horses are 
entered in the event.
    <bullet> Requiring the management of any horse show, exhibition, 
sale, or auction that elects to utilize an APHIS representative or HPI 
to inspect horses to have at least one farrier physically present if 
more than 100 horses are entered in the event, or if there are 100 or 
fewer horses to have a farrier on call within the local area to be 
present if requested by an APHIS representative or HPI. We stated that 
farriers would not be required for shows that do not utilize an 
inspector.
    <bullet> Adding new reporting and recordkeeping requirements for 
management of all horse shows, exhibitions, sales, and auctions covered 
under the Act. These include retaining records for at least 90 days of 
any horse allowed to show under therapeutic treatment, informing APHIS 
and reporting event information at least 30 days in advance of the 
event, and notifying APHIS of changes to event information at least 15 
days in advance of the event. These requirements were intended to 
prevent disqualified persons and horses from participating in HPA-
covered events and to give APHIS sufficient time to schedule an APHIS 
representative to inspect at the event, if requested.

Discussion of Comments

    We solicited comments concerning our proposal for 60 days ending 
October 20, 2023. We received 8,787 comments on the proposed rule 
through submissions received via regulations.gov, email, and U.S. mail. 
Comments received by APHIS via email and U.S. mail were copied into 
regulations.gov. We conducted a thorough and unbiased review of all 
comments, the majority of which consisted of variations on a single 
form letter supporting the rule submitted by over 7,000 persons, as 
well as a form letter submitted by an organization supporting the rule 
with 107, 257 signatories listed. Variations of other form letters 
generally opposing or supporting the proposed rule were submitted by 
smaller groups of commenters. Other comments were from: State and 
Federal elected officials, including U.S. Senators and Representatives; 
State agricultural agencies and farm bureaus; gaited horse breeder 
organizations, trotting horse federations and organizations, and other

[[Page 39197]]

domestic and foreign horse industry organizations; equine veterinarians 
and veterinary associations; horse rescue and animal welfare advocacy 
organizations; horse owners, trainers, and exhibitors; and saddle 
clubs, farriers, cattle grower associations, small business owners, and 
other interested persons. We address the issues the commenters raised 
in the order that they appear in the regulatory text of the proposed 
rule.
    Based on the comments received, we are finalizing the proposed 
rule, including these significant modifications:
    <bullet> We have revised proposed Sec.  11.5, so that it provides 
for appeal of a disqualification rather than appeal of an inspection 
report.
    <bullet> We have elected not to finalize the proposed 270-day 
implementation period for phasing out pads, wedges, and artificial toe 
extensions on Tennessee Walking Horses and racking horses as provided 
for in Sec.  11.6(c).
    <bullet> We have elected not to provide management of a covered 
horse show, exhibition, sale, or auction with the option of requesting 
a variance at least 15 days before an event if no APHIS representative 
or HPI is available. This requirement was in proposed Sec.  
11.16(a)(6).
    <bullet> We have elected not to require that veterinarians be 
licensed as a qualification for authorization as an HPI. This 
requirement was in proposed Sec.  11.19(a)(1).
    <bullet> We have revised the language of our proposed description 
of dermatological conditions indicative of soring by making the list of 
conditions illustrative, rather than requiring that the presence of any 
one condition must result in a diagnosis of soring. We made this 
revision and moved this provision to revised Sec.  11.7.
    We explain why we made each of these changes to the proposed 
regulations under the relevant section below. Our responses to economic 
issues and questions received from commenters are included in the 
economic analysis summarized in this final rule and available as a 
supporting document on regulations.gov (see footnote 10).

Comments on Supporting Data in the Proposal

    We included in the proposal two tables showing inspection data for 
HPA-covered events from fiscal years (FY) 2017 through 2022. Table 1 
presents Performance division horse inspection data for HPA-covered 
events from FY 2017 to FY 2022. Table 2 presents flat-shod horse 
inspection data for HPA-covered events from the same period. Each table 
shows, by year, the number of horses inspected by DQPs at events where 
APHIS officials were not present, the number of noncompliance 
violations the DQPs found, and the rate of noncompliance (number of 
horses inspected divided by the number of violations found). Each table 
also shows the number of horses inspected by DQPs at events where APHIS 
officials were present, the number of noncompliance violations the DQPs 
found in the presence of APHIS officials, and the rate of 
noncompliance. Finally, each table shows the number of horses inspected 
by APHIS officials at these events, the number of noncompliance 
violations they found, and the rates of noncompliance.
    The noncompliance rates detected by DQPs when APHIS is present and 
when APHIS is not present are calculated using the same method, by 
using the number of noncompliances detected by DQPs and the number of 
horse entries inspected by DQPs. We cited this data in the proposal to 
highlight the differences between noncompliances detected by DQPs when 
APHIS officials are present to observe DQP inspections and when APHIS 
officials are not present. These differences, in our view, are 
significant in that they suggest that in the absence of APHIS officials 
checking their work, DQPs are passing horses during inspections that 
they likely know would not pass if checked by an APHIS official. We 
therefore can only conclude that some DQPs are unwilling to correctly 
palpate and, therefore, make a proper diagnosis of the horses they 
inspect. As a result, the current DQP system is not contributing to the 
goal of eliminating soring in Tennessee Walking Horses and racking 
horses, particularly those that show as Performance division horses in 
pads and action devices. To underscore this point, the table data for 
flat-shod horses shows dramatically lower rates of noncompliance in 
APHIS' inspections of horses, although a smaller discrepancy in rates 
of noncompliance remains when DQPs are inspecting horses when APHIS 
VMOs are present and when they are not.
    Several commenters stated that the noncompliance data we included 
in tables 1 and 2 is incomplete, misleading, and based on a subjective 
inspection protocol that renders any conclusions APHIS draws from the 
data as being unreliable. One such commenter noted that the data 
reproduced in the tables in the proposal does not match up with 
activity reports publicly available on APHIS's Horse Protection program 
website. The commenter noted that the proposed rule indicates that USDA 
inspectors detected a total of 323 instances of noncompliance in FY 
2022, but that the activity report for that year shows only 117 
instances. The commenter stated that USDA needs to explain the 
discrepancy, as it calls into question the higher rates of 
noncompliance at these events based on the APHIS VMO inspection 
findings.
    The commenter is comparing data sets from two report types that are 
not commensurable. The fiscal year activity report that the commenter 
found online \13\ only includes noncompliance data reported by APHIS 
VMOs to management of the regulated event for possible 
disqualification. The report does not include instances of 
noncompliance that were observed by an APHIS VMO and referred to a DQP 
for appropriate follow-up inspection or remedial action. Those 
instances, which often result in actions taken by the DQPs themselves, 
are not part of the activity report, but were part of the data sets in 
tables 1 and 2 of the proposed rule. The fiscal year activity report 
also does not include instances of noncompliance that were observed by 
a DQP during inspection but reported by the DQP directly to management. 
In sum, the data in tables 1 and 2 of the proposed rule provide a more 
accurate depiction of the rate of noncompliance than the activity 
reports, which show a more limited range of noncompliance data.

    \13\ APHIS Horse Protection Program FY 2022 Activity Report: 
<a href="https://www.aphis.usda.gov/animal_welfare/downloads/hp/fy2022-horse-program-activity-report.pdf">https://www.aphis.usda.gov/animal_welfare/downloads/hp/fy2022-horse-program-activity-report.pdf</a>.
---------------------------------------------------------------------------

    We included the tables in the proposed rule to show that DQPs were 
far more likely to identify noncompliance of any sort when APHIS VMOs 
were also present and observing at the event.
    The commenter also stated that the data in the proposed rule 
showing higher rates of soring detected by VMOs is invalid because it 
was not based on a random sample of horses inspected. As a result, the 
USDA's data purportedly showing higher rates of noncompliance detected 
by USDA inspectors cannot properly be treated as showing the violation 
rate at Tennessee Walking Horse events because it is based on 
inspections of a subset of horses that were singled out in advance as 
being suspected of soring.
    As the commenter indicated, we indeed acknowledged in the proposed 
rule that many horses selected by VMOs for inspection ``are more likely 
to be diagnosed [as sore], as that sample

[[Page 39198]]

presented indications of soring prior to inspection.'' We have never 
claimed that inspections of horses for soring are randomized, although 
we also inspect horses showing no indications of soring. The data is 
not restricted to a random sample because APHIS does not operate in an 
environment in which a fully random sampling is warranted, or, indeed, 
possible.
    After 50 years of enforcing the HPA, APHIS has amassed an aggregate 
body of data indicating the Tennessee Walking Horse and racking horse 
industry is disproportionately likely to sore their horses, and DQPs in 
the industry are disproportionately unlikely to detect the soring. This 
is true regardless of the year in question, the number of inspections 
conducted, or other controls applied. For example, in 2023, APHIS VMOs 
conducted significantly more inspections than in 2022; yet the rate of 
soring detected remained almost identical. Our inspection efforts under 
the HPA thus properly focus on those industries that present a much 
higher risk of soring their horses based on prior experience over the 
past 50 years.
    It is also worth noting, as we did in the proposed rule, that both 
USDA-OIG and the NAS study committee reached similar conclusions 
regarding the Tennessee Walking Horse and racking horse industry, and 
that the NAS study was jointly requested not only by APHIS, but also by 
the Tennessee Department of Agriculture and the Tennessee Walking Horse 
Breeders Foundation.
    Further, the commenter stated that the data cited in tables 1 and 2 
of the proposal is misleading because it reflects rates for all HPA 
noncompliance violations, not just soring violations. The commenter 
added that by failing to distinguish between violations that do and do 
not involve soring, USDA overinflates the data that supposedly shows 
soring violations, and that the actual rate of soring is likely even 
lower than that reported.
    The commenter is correct that the data cited in the proposal 
includes HPA noncompliances that are not categorized as ``sore'' 
noncompliances. However, we disagree that the tables were misleading. 
The proposed rule did not purport to indicate that tables 1 and 2 
contained only instances of noncompliance indicative of soring. Again, 
the articulated purpose of tables 1 and 2 in the proposed rule was to 
show that there are still higher rates of soring, insofar as DQPs were 
much more likely to identify all types of noncompliance, both actual 
soring and otherwise, when APHIS VMOs were also present at the event. 
And, in fact, the majority of these noncompliances across all years in 
the data chart were indeed categorized as ``sore.'' Aside from a slight 
decrease in FY2019, the percentage of noncompliances categorized as 
``sore'' continued to increase year after year, as the following table 
shows:

    The same commenter claimed that the data on noncompliances reported 
by APHIS resulted from a subjective inspection process that has been 
shown to be incapable of producing reproducible results. The commenter 
stated that USDA implemented a requirement in late 2016 that a horse 
found in violation of the HPA by a VMO must be re-inspected by a second 
VMO, if present. USDA removed that requirement in 2021 because we 
concluded that a single VMO's finding of soring was reliably accurate 
without the need for additional confirmation. The commenter stated, 
however, that when the second inspection rule was in use between 2017 
and 2021, the number of violations dropped significantly whenever two 
VMO inspectors had to agree on a finding of a violation. The commenter 
concluded, therefore, that the number of violations APHIS reported in 
the tables in FY 2017, FY 2021, and FY 2022 is likely lower than what 
is reported.
    The fact that APHIS VMOs occasionally reach different conclusions 
about whether a horse is sore does not categorically invalidate the 
ability or the reasoned judgment of a trained inspector with respect to 
detecting and diagnosing soreness in horses. The protocol referred to 
by the commenter required APHIS VMOs to make exactly the same findings 
in order to document a violation, and, as the NAS study stated, ``[t]he 
requirement that two VMOs must make exactly the same findings (i.e., 
sensitive on the lateral pastern but not bulbs of heels or medial 
pastern) does not consider changes that may occur over time between 
examinations, how the horse may respond to repeated palpation, or how 
the presence of foreign substances either parenterally or topically may 
influence findings over time.'' \14\ Further, the NAS study noted that 
``[d]istractions and stressors can inhibit a horse's sensitivity to and 
expression of pain, such that detection of soreness would be missed, or 
a horse's reaction to distractions could be incorrectly attributed to 
pain. Moreover, when more than one

[[Page 39199]]

inspector examines the horse, its behavior may differ between the two 
inspections if the number and type of distractions and stressors at 
that location and time also differ.'' \15\

    \15\ Ibid., Conclusion 3-1, page 52.
---------------------------------------------------------------------------

    While we agree with the commenter that inspection does often entail 
a professional's judgment that observable symptoms are indicative of 
soring, we disagree with the commenter's characterization of the 
inspection process as subjective and incapable of producing 
reproducible results. The NAS study describes the current process APHIS 
uses for detecting soreness, which involves informed observation of the 
horse's movement and posture and palpation of the limbs, as ``the gold 
standard for detecting local pain and inflammation. These examination 
methods are known to be valid and reliable when performed by 
veterinarians who are trained and highly experienced in detecting 
lameness and pain. They are employed to detect lameness, injury, and 
pain in all breeds of horses that are used in competitions, shows, 
recreational riding, work, breeding, and teaching.'' \16\
---------------------------------------------------------------------------

    \16\ Ibid., Finding 2-2, page 33.
---------------------------------------------------------------------------

    The same commenter also stated that the NAS study recognizes and 
supports their position that USDA's current inspection protocol is 
predominantly subjective and does not yield reproducible and consistent 
results. As evidence, the commenter stated that USDA's own inspectors 
cannot agree on whether an individual horse is sore. The commenter 
cited inspection data from one horse event in 2016, which showed that 
when two different USDA officials inspected the same horses, they could 
not agree on the same conclusion up to 52 percent of the time. Based on 
this discrepancy, the commenter stated that APHIS can draw no valid 
conclusions that Agency inspectors generally find a higher rate of 
violations and cannot use data obtained from that inspection protocol 
as evidence that soring persists.
    The commenter's characterization of the NAS study distorts its 
content. The study did not suggest that the current inspection protocol 
is incapable of detecting soring; to the contrary, as noted above, it 
considered the current practice for detecting soreness to be the ``gold 
standard'' for doing so. NAS also found, however, that APHIS' 
inspection protocol was actually overly prescriptive. At the time of 
the NAS study, a second VMO was required to inspect a horse if the 
first VMO initially found it to be bilaterally sore and, to warrant a 
finding of soring and disqualification, ``the second inspection must be 
exactly the same as to the area of apparent pain and the type of 
response given by the horse as well as findings of skin changes 
indicative of previous injury.'' \17\ Thus, even if the second VMO also 
found the horse to be sore, any difference between the first and second 
inspections, however minor, could invalidate the finding. The NAS study 
noted that ``[f]ailure by a VMO to adhere to such a prescriptive 
protocol could ``allow for possible objections to the VMO's finding by 
the horse custodian,'' adding that ``inspection by a second VMO may 
cast doubt on the ability of VMOs to detect pain or other abnormalities 
and may negatively affect the VMO's ability to make appropriate 
judgments.'' \18\ The study recommended that properly qualified and 
trained individuals be afforded greater latitude to make a professional 
judgment of soring under a less prescriptive protocol, noting that 
under the two-VMO protocol, a determination of soring can easily be 
overturned when it should not; in other words, a false negative on 
reinspection is more likely the outcome than is a false positive of 
soring.

---------------------------------------------------------------------------

    With respect to the inspection data cited by the commenter from one 
show in 2016, the nature of the prescriptive protocol may explain why 
inspections by different VMOs resulted in a different finding 52 
percent of the time at that show. Even so, the single show data the 
commenter cited is not a representative sampling, nor does it address 
the ability of APHIS VMOs to detect soring.
    In claiming the unreliability of the USDA inspection protocol and, 
thus, of the data from those inspections, the commenter also referred 
to a research project included in the NAS study report, conducted by 
Dr. Paul Stromberg, that examined skin biopsies from Tennessee Walking 
Horses disqualified for scar rule violations. Dr. Pamela E. Ginn, a 
member of the NAS study committee and a board[hyphen]certified 
veterinary pathologist and a specialist in veterinary dermatopathology, 
also examined the biopsies and reviewed Dr. Stromberg's conclusions.
    As this comment pertains mainly to questioning the accuracy of the 
scar rule, we respond to the comment under the heading ``Dermatologic 
Conditions Indicative of Soring'' below.
    Another commenter, citing the same 2016 event inspection data as 
the commenter above, stated that APHIS is relying on different 
``violation'' rates when APHIS officials are present and when they are 
not present, and that this is misleading.
    We interpret the commenter to mean that it is misleading for APHIS 
to show that DQPs are allowing sore horses to pass inspection when not 
under the supervision of APHIS officials and citing the discrepancy in 
rates. We disagree that this is misleading because we are simply citing 
the results of DQP inspections under different conditions. We agree 
with the commenter that DQPs find more noncompliances when APHIS 
officials are present.
    A commenter also questioned the reliability of the noncompliance 
data by stating it is based on citations issued by APHIS VMOs lacking 
equine experience. The commenter noted that the NAS study report 
explained that ``examinations should be performed not only by a 
veterinarian, but by a veterinarian who has equine experience.''
    We disagree that noncompliance data presented in the proposed rule 
should be considered unreliable because certain noncompliance was 
detected by individuals lacking equine experience, although if lack of 
experience is an issue, we note that it is DQPs, rather than APHIS 
VMOs, who are doing most of the inspections and are so situated 
currently. We note that APHIS VMOs, by virtue of being veterinarians 
working within the Horse Protection program, are experienced with 
equines and have received training in equine medicine. APHIS' training 
of VMOs involves practice in learning and applying medically 
established methods of diagnosing soring. We intend to extend a similar 
rigorous level of HPI training to qualified persons with equine 
experience under the changes we proposed to the Horse Protection 
program.
    The commenter also stated that APHIS' inspection methods fail to 
account for injuries or sensitivity that may occur from ``legal'' 
activity that occurs during a show, comparing the minor sensitivity 
that may result from normal activity during a show to what a human 
athlete might feel after competing. The commenter stated that USDA 
unfairly disqualifies horses post-show for such sensitivity when no 
evidence of actual soring is found, and that USDA disregards any 
plausible explanations for sensitivity not resulting from soring.
    We disagree with the commenter, in that any show activity 
considered ``normal'' would not result in a response to sensitivity 
painful enough to be confused with soring, particularly if an

[[Page 39200]]

inspector has the training and experience to palpate and diagnose 
horses accurately. To this end, we note again that palpation as 
practiced by APHIS VMOs was determined by the NAS study to be the 
``gold standard'' in detecting local pain and inflammation indicative 
of soring, particularly when administered by a properly qualified and 
trained veterinarian. We also note that medical professionals such as 
VMOs are specifically trained in making the sort of differential 
diagnoses cited by the commenter based on their professional judgment. 
In addition, our records indicate that horses at flat-shod shows that 
also compete athletically almost never exhibit soreness on post-show 
inspection. We see no reason to discount our data on noncompliance as 
being unreliable or misleading for the reason the commenter claims.
    The commenter also stated that the data does not support USDA's 
decision to treat Tennessee Walking Horses and racking horses 
differently from other breeds.\19\ The commenter explained that USDA 
based its decision that Tennessee Walking Horses require special rules 
on the conclusion that violation rates are much higher at Tennessee 
Walking Horse events than at competitions with other breeds, but that 
the USDA provided no data showing violation rates for other breeds as 
comparison. The commenter added that USDA apparently does not have data 
for other breeds because it does not inspect those breeds the same way 
it inspects Tennessee Walking Horses, and concluded from this that the 
Agency should not place more onerous restrictions on the breed without 
evidence to support that action. Another commenter echoed this point, 
stating that other breeds have not been subject to decades of stringent 
subjective inspections and that they are rarely inspected by the same 
protocols as Tennessee Walking Horses and racking horses.
---------------------------------------------------------------------------

    \19\ Related to this point, we note that in current Sec.  
11.2(c) and (d) restrictions on substances and workouts specific to 
Tennessee Walking Horses and racking horses have long been part of 
the regulations.
---------------------------------------------------------------------------

    In the proposed rule, we provided several reasons why APHIS does 
not inspect other breeds for soring to the degree that we inspect 
Tennessee Walking Horses and racking horses. As the commenter noted, we 
indicated in the proposal that we base this approach on our informed 
knowledge and monitoring for signs of soring in other breeds and, as a 
means to further improve our ability to monitor the activities of other 
breeds, we proposed in Sec.  11.16(a) that management of all horses 
covered under the Act report their events 30 days in advance. Moreover, 
the current regulations in Sec.  11.2(c) and (d) and Sec.  11.6 listing 
prohibitions specific to Tennessee Walking Horses and racking horses 
(provisions regarding substances and workouts) already treat these 
breeds differently, as findings of soring are highly concentrated in 
these breeds and infrequent in all other breeds. We also note that in 
the occasional inspections we conduct on other breeds, we have found 
only rare instances of noncompliance, and we maintain records of such 
noncompliances.
    In the small sample of data from events attended by APHIS where 
other breeds were inspected, we found a very low noncompliance rate 
comparable to that found in flat-shod Tennessee Walking Horses and 
racking horses. These events included Missouri Fox Trotters, Rocky 
Mountain, and Spotted Saddle Horses. The average noncompliance rate 
detected by APHIS from FY 2017 to FY 2022 at these events was 0.8 
percent, whereas the average noncompliance rate detected by APHIS for 
flat-shod horses across the same years was 1.9 percent. In table 1 of 
the proposal, during the same period, the average noncompliance rate 
from APHIS inspections of Tennessee Walking Horses and racking horses 
competing in Performance division events was 25 percent, and 34.1 
percent in FY 2022 alone.
    While isolated cases of soring have been reported in other horse 
breeds, we question the commenter's implication that only regular 
inspections of other horse breeds will confirm these breeds to be at 
lower risk of soring, as opposed to other means of knowledge gathering 
sufficient to establish an informed level of risk, which includes 
occasional inspections. We noted, for instance, that the distinctive 2-
inch-high stacked pads worn by Tennessee Walking Horses and racking 
horses are not used at shows by any other breed. In addition, 
``[e]quine veterinarians on the NAS committee noted that skin changes 
seen on the pasterns of Tennessee Walking Horses are not observed on 
the pasterns of other breeds of horses (Arabians, American Saddlebreds, 
Morgan horses), which also train with action devices such as chains and 
rollers but do not wear them when shown at competitions.'' \20\
---------------------------------------------------------------------------

    \20\ NAS study, page 81.
---------------------------------------------------------------------------

    While all horse breeds are subject to provisions of the Act, we 
proposed Tennessee Walking Horse- and racking horse-specific 
prohibitions on certain items and practices because USDA has 50 years 
of data showing a documented record of soring in these breeds that 
simply does not exist for other breeds. On the other hand, if USDA were 
considering establishing new regulations in a currently unregulated 
community, presuming beforehand that one class of entity will be more 
noncompliant than other classes without evidence would be 
inappropriate.
    Finally, soring imparts little to no advantage to competitors at 
other breed shows, as the gaits on which most breeds are evaluated are 
noticeably distinct from the exaggerated ``big lick'' step featured at 
many Tennessee Walking horses and racking horse events. While we make a 
distinction between Tennessee Walking Horses and racking horses and 
other breeds by prohibiting the use of pads, artificial extension of 
the toe, and action devices, we note that it is not necessarily the pad 
or action device in itself that can cause soring per se, but rather 
their specific application and use in training of a horse. Pads and 
wedges in certain forms, for instance, can actually be used in training 
in such a way as to cause soring. We address this issue further in the 
comment responses below.

Definitions

    In Sec.  1.1, we proposed adding definitions for custodian, day(s), 
event manager, Horse Protection Inspector (HPI), local area, 
participate, and therapeutic treatment.
    A commenter stated that a definition should be added for 
stewarding.
    We believe that new Sec.  11.6(b)(21) adequately defines what we 
consider to be stewarding. The paragraph prohibits the use of whips, 
cigarette smoke, or similar actions or paraphernalia to distract a 
horse or to otherwise impede the inspection process during an 
examination, including but not limited to, holding the reins less than 
18 inches from the bit shank. All such actions constitute stewarding.
    The same commenter stated that a definition should be added for 
``substances.''
    In a 2016 proposed rule to revise the HPA regulations (81 FR 49112-
49137, Docket No. APHIS-2011-0009), we proposed adding such a 
definition.\21\ However, in response to comments at that time, we 
refrained from including it in the regulations. In brief, commenters 
raised questions about the regulatory status of substances having 
multiple uses and what constitutes a substance that should be 
prohibited, as

[[Page 39201]]

well as requests to provide a definition that covers all substances of 
concern.
---------------------------------------------------------------------------

    \21\ To view this proposed rule, go to <a href="https://www.regulations.gov/document/APHIS-2011-0009-0001">https://www.regulations.gov/document/APHIS-2011-0009-0001</a>.
---------------------------------------------------------------------------

    As no useful definition of ``substances'' can encompass all their 
uses and abuses for the purposes of regulation, we believe the 
regulation is adequate and have opted not to define the term. As 
explained elsewhere in this document, the Act provides us with the 
authority to restrict or prohibit practices, including the use of 
substances, that can cause soring or mask evidence of it.
    We proposed revising the definitions of action device, 
Administrator, APHIS representative, inspection, management, person, 
and sponsoring organization. We proposed removing the definitions for 
APHIS Show Veterinarian, Designated Qualified Person or DQP, horse 
industry organization or association, lubricant, Regional Director, and 
show manager. Our responses to comments received on these changes are 
addressed below.
    We proposed no changes to, and received no substantive comments on, 
the definitions for Act, Animal and Plant Health Inspection Service 
(APHIS), Department, exhibitor, horse, horse exhibition, horse sale or 
horse auction, horse show, Secretary, sore, and State.
    We proposed revising the definition for action device by adding 
beads and bangles to the list of such devices.
    One commenter recommended that we also remove the word ``joint'' in 
the definition when referring to the fetlock, adding that the fetlock 
includes the joint and this wording implies it may be acceptable to 
strike the area between the coronary band and the fetlock joint.
    The term ``fetlock joint'' has been part of the HPA regulations 
since 1979 and is only included in the definition of action device. 
While we agree that the term ``fetlock'' includes the 
metacarpophalangeal and metatarsophalangeal joints, both ``fetlock'' 
and ``fetlock joint'' are used in scientific literature interchangeably 
to refer to the same region of a horse's distal limb. We are finalizing 
as proposed.
    We proposed revising the definition for Administrator by adding 
U.S. mail and email addresses for sending mail to the Administrator of 
APHIS. We received no comments on this revision and are finalizing as 
proposed.
    We proposed removing the definition for APHIS Show Veterinarian and 
revising the definition of APHIS representative. The current definition 
of APHIS representative is any employee of APHIS, or any officer or 
employee of any State agency who is authorized by the Administrator to 
perform inspections or any other functions authorized by the Act, 
including the inspection of the records of any horse show, horse 
exhibition, horse sale or horse auction. We proposed revising this term 
to read ``any employee or official of APHIS,'' which includes APHIS-
employed veterinarians attending shows in an official capacity. APHIS 
representatives will include qualified full-time and intermittent VMOs 
employed by APHIS to inspect horses for soring. HPIs, on the other 
hand, will not be APHIS representatives under this definition because 
they are not employees of APHIS and not compensated by the Agency, but 
will be authorized to conduct inspections and will contract as third 
parties with event management for their services. We received no 
comments specifically addressing this change and are finalizing as 
proposed.
    We proposed adding a definition for the term custodian, which we 
proposed to mean any person who has initial control of and who presents 
a horse for inspection at any horse show, horse exhibition, horse sale, 
or horse auction. We noted that a person acting as custodian may 
typically perform additional roles, such as owner, exhibitor, seller, 
or transporter. Also, the custodian must be able to provide required 
information about the horse as required in part 11.
    A few commenters expressed support for the new definition but 
recommended that we limit the definition to ``any adult person, of the 
age of 18 or older,'' noting that children should not be allowed to 
present horses for inspection.
    We agree with the commenter's recommendation and are modifying the 
definition in this final rule by adding ``any adult person, age 18 or 
older''. If a minor were found to be in violation with the regulations, 
the person's status as a minor could complicate legal liability and 
responsibility for purposes of addressing the infraction and enforcing 
the Act. Custodian of a noncompliant horse is a role APHIS pursues for 
enforcement.
    Another commenter recommended that we insert the words ``and/or 
subsequent'' after the word ``initial,'' as the proposed wording would 
not address the question of subsequent control of the horse.
    Occasionally, the person who has initial control of the horse will 
have someone else take their place during the inspection process. That 
person will have to meet the same requirements as the custodian who had 
initial control of the horse. We agree with the commenter's 
recommendation and will address it by removing ``initial'' from the 
definition. By removing this word, the term accounts for any person 
having control of the horse at any time, initially or subsequently.
    We proposed and are adding the term day(s) to Sec.  1.1, and 
defining it to mean business days, i.e., days other than weekends and 
Federal holidays. In several instances, the regulations require the 
submission of reports or records with a period of days, and we wish to 
clarify that weekends and Federal holidays are not included within that 
day count. We received no comments specifically addressing this 
addition and are finalizing as proposed.
    The current definition of Designated Qualified Person is ``a person 
meeting the requirements specified in Sec.  11.7 . . . who has been 
licensed as a DQP by a horse industry organization or association 
having a DQP program certified by the Department and who may be 
appointed and delegated authority by the management of any horse show, 
horse exhibition, horse sale or horse auction under section 4 of the 
Act to detect or diagnose horses which are sore or to otherwise inspect 
horses and any records pertaining to such horses for the purposes of 
enforcing the Act.''
    We proposed removing the term Designated Qualified Person or DQP 
and its definition, as well as all regulatory requirements in the 
regulations pertaining to them. Instead, APHIS will screen, train, and 
authorize Horse Protection Inspectors or HPIs qualified to conduct 
inspections of horses, devices, and records for the purposes of 
determining compliance with the Act at horse shows, exhibitions, sales, 
and auctions. HPIs, preferably veterinarians, will be authorized by 
APHIS pursuant to proposed Sec.  11.19 and appointed by management of 
the event. Accordingly, we are including a definition for Horse 
Protection Inspector in the regulations, included below. We received no 
comments specifically addressing this proposed action and are 
finalizing as proposed.
    We proposed to add the term event manager to mean the person who 
has been delegated primary authority by a sponsoring organization for 
managing a horse show, horse exhibition, horse sale, or horse auction. 
An individual event manager will need to be designated even if the 
event is managed by a team of persons. This definition will clarify 
management responsibility. We received no comments specifically 
addressing this addition and are finalizing as proposed.
    The term horse industry organization or association is currently 
defined as

[[Page 39202]]

``an organized group of people, having a formal structure, who are 
engaged in the promotion of horses through the showing, exhibiting, 
sale, auction, registry, or any activity which contributes to the 
advancement of the horse.'' We proposed removing the term horse 
industry organization or association and its definition, as all 
regulatory requirements under the Act pertaining to these groups, 
including requirements for certification of DQP programs, 
recordkeeping, and other requirements assigned to them will no longer 
be included in the revised regulations.
    A few commenters opposed removal of the term and removal of the 
role played by HIOs under the current program. One commenter stated 
that the change will impose significant new recordkeeping and reporting 
requirements, and new tasks such as crowd control, on local show 
managers.
    We are making no changes based on these comments. We disagree with 
the commenter's point that the proposed regulatory changes eliminate 
HIOs or prevent them from working with show management. As we noted in 
the proposal, HIOs are free to continue supplying other services to 
shows and events not subject to regulation, including registering 
participants and coordinating event logistics, supplying show judges, 
and promoting events. This rulemaking does not affect their freedom to 
contract with event management to perform these services. The proposed 
removal of the term was solely to reflect the fact that they would no 
longer have a distinct role specifically pertaining to APHIS' Horse 
Protection regulations.
    We proposed adding the term Horse Protection Inspector (HPI) to 
mean a person meeting the qualifications in proposed Sec.  11.19 whom 
the Administrator has authorized as an HPI and who may be appointed and 
delegated authority by the management of any horse show, horse 
exhibition, horse sale or horse auction under section 4 of the Act to 
detect or diagnose horses which are sore or to otherwise inspect horses 
and any records pertaining to such horses for the purposes of detecting 
or diagnosing soring.
    A commenter stated that we should clarify in the definition that 
HPIs are not APHIS representatives.
    We agree, and will clarify the definition we proposed by adding a 
sentence stating that ``HPIs are not employees of APHIS.''
    The current regulations define inspection to mean ``the examination 
of any horse and any records pertaining to any horse by use of whatever 
means are deemed appropriate and necessary for the purpose of 
determining compliance with the Act and regulations. Such inspection 
may include, but is not limited to, visual examination of a horse and 
records, actual physical examination of a horse including touching, 
rubbing, palpating and observation of vital signs, and the use of any 
diagnostic device or instrument, and may require the removal of any 
shoe, pad, action device, or any other equipment, substance or 
paraphernalia from the horse when deemed necessary by the person 
conducting such inspection.''
    To emphasize that any means of determining compliance with the Act 
and regulations must be approved by APHIS, we proposed revising the 
definition of inspection to include the words ``any visual, physical, 
and diagnostic means approved by APHIS to determine compliance with the 
Act and regulations,'' with some illustrative examples. While we 
received comments on what inspections should include and address them 
elsewhere in this document, we received no comments on the definition 
itself and are finalizing as proposed.
    We proposed adding a definition for local area, which we define as 
the area within a 10-mile radius of the horse show, horse exhibition, 
horse sale, or horse auction. This term will be added in conjunction 
with Sec.  11.13(b)(3), which requires event management to have a 
farrier on call within the local area if requested by an APHIS 
representative or HPI appointed by management and 100 or fewer horses 
are entered in the horse show, exhibition, sale, or auction. When over 
100 horses are entered in an event, management will be required to have 
a farrier onsite unless they elect to enforce the HPA without recourse 
to an inspector.
    A commenter disagreed with the proposed definition of local area 
and advised a 30-mile radius to compromise the local area, while 
another commenter suggested it be increased to greater than 40 miles.
    We are finalizing as proposed. A farrier may be required to provide 
services to assist an APHIS representative or HPI in conducting an 
inspection, such as removing a shoe. A 10-mile radius allows the on-
call farrier to be close enough to arrive at a show promptly if so 
requested by an APHIS representative or HPI. This, in turn, forestalls 
delays in conducting inspections. We also note that the first commenter 
also stated that most horse events retain a farrier onsite, and the 
other commenter assumed that farriers would not be onsite in 
recommending a radius of more than 40 miles.
    The term lubricant in the current definitions means ``mineral oil, 
glycerine or petrolatum, or mixtures exclusively thereof, that is 
applied to the limbs of a horse solely for protective and lubricating 
purposes while the horse is being shown or exhibited. . . .'' We 
proposed removing the definition for lubricant and prohibiting the use 
of lubricants on the limbs of all Tennessee Walking Horses and racking 
horses; the current regulations allow the use of lubricants for 
Tennessee Walking Horses and racking horses under certain 
circumstances. Some commenters opposed prohibiting lubricants but were 
silent on removal of the definition itself. We discuss our reasons for 
prohibiting lubricants to prevent the soring of horses in this document 
under the heading ``Prohibitions for Tennessee Walking Horses and 
racking horses.''
    We proposed revising the current definition of management, which 
means ``any person or persons who organize, exercise control over, or 
administer or are responsible for organizing, directing, or 
administering any horse show, horse exhibition, horse sale or horse 
auction and specifically includes, but is not limited to, the 
sponsoring organization and show manager.'' We received no comments on 
this proposed change to replace ``show manager'' with ``event manager'' 
and are finalizing as proposed.
    We proposed adding a definition of participate to Sec.  1.1 to mean 
engaging in any activity, either directly or through an agent, beyond 
that of a spectator in connection with a horse show, horse exhibition, 
horse sale, or horse auction, and includes, without limitation, 
transporting, or arranging for the transportation of, horses to or from 
equine events, personally giving instructions to exhibitors, being 
present in the warm-up or inspection areas or in any area where 
spectators are not allowed, and financing the participation of others 
in equine events. We received no comments specifically addressing this 
proposed addition and are finalizing as proposed.
    Person in the regulations means ``any individual, corporation, 
company, association, firm, partnership, society, organization, joint 
stock company, or other legal entity.'' We proposed revising the 
definition by adding ``State or local government agency'' to the list 
of illustrative examples of a person. This change highlights that State 
and local government agencies also fall under the definition of person 
for the purposes of enforcing the regulations.

[[Page 39203]]

We received no comments specifically addressing this proposed revision 
and are finalizing as proposed.
    As currently defined in the regulations, Regional Director means 
``the APHIS veterinarian who is assigned by the Administrator to 
supervise and perform official duties of APHIS under the Act in a 
specified State or States.'' We proposed to remove the term from Sec.  
11.1 because APHIS representatives performing Horse Protection duties 
are no longer organized and managed by region. We received no comments 
specifically addressing this revision and are finalizing as proposed.
    The regulations currently define sore to mean, among other things, 
that ``a person has engaged in a practice involving a horse and, as a 
result of such . . . practice, such horse suffers, or can reasonably be 
expected to suffer, physical pain or distress, inflammation, or 
lameness when walking, trotting, or otherwise moving.'' Although we 
proposed no changes to the definition of sore, one commenter asked if 
the part of the definition referring to a person ``engaged in a 
practice involving a horse'' is applicable to a scenario in which a 
horse is injured in its stall.
    We are finalizing as proposed. The regulatory definition of sore is 
patterned after the statutory definition. The scenario mentioned by the 
commenter is presumably accidental. If, in the professional judgment of 
a qualified inspector, the horse is not sore, and presuming no other 
noncompliance is identified, the horse could be shown under the 
regulations. However, regardless of the commenter's question, if the 
horse is injured it should first be evaluated to determine if it needs 
medical attention.
    Another commenter stated that the definition of sore is not 
enforceable unless ``a person'' is actually observed committing any of 
the actions prohibited under the definition.
    We disagree with the commenter. The Act does not require that an 
act of soring be observed. To the contrary, the Act defines ``sore'' 
based on the condition of the horse after the act has occurred. See 15 
U.S.C. 1821(3) (defining ``sore'' as when ``an irritating or blistering 
agent has been applied,'' ``any burn, cut, or laceration has been 
inflicted,'' any tack, nail, screw, or chemical agent has been 
injected,'' or ``any other substance or device has been used''). 
Moreover, the commenter's suggestion would deprive properly qualified 
and trained inspectors from making a professional judgment that a 
practice that resulted in soring had occurred prior to the inspection.
    Sponsoring organization in the current regulations means ``any 
person under whose immediate auspices and responsibility a horse show, 
horse exhibition, horse sale, or horse auction is conducted.'' We 
proposed revising the current definition to mean ``any person or entity 
whose direction supports and who assumes responsibility for a horse 
show, horse exhibition, horse sale, or horse auction that has, is, or 
will be conducted.'' We are making this change to clarify that an 
``entity'' is also included under the definition, and to ensure that 
any person or entity supporting and assuming responsibility for such an 
event also falls under the definition. Our proposed revision also 
clarifies that the sponsoring organization's responsibility applies 
whether the event in question has already occurred or is yet to occur. 
We received no comments specifically addressing this revision and are 
finalizing as proposed.
    We also are adding a definition for the term therapeutic treatment 
to mean relating to the treatment of disease, injury, or disorder by or 
under the supervision of a person licensed to practice veterinary 
medicine in the State in which such treatment was prescribed. We 
proposed to define this term to ensure that therapeutic practices 
applied to any horse covered under the regulations are administered or 
overseen by qualified veterinarians only. This definition corresponds 
with the exceptions allowed under the definition of sore for any 
practice involving therapeutic treatment of a horse by or under the 
supervision of a licensed veterinarian.
    A commenter stated that the definition should include a set time 
limit to be part of the prescribed therapeutic use of pads and other 
restricted items.
    We are making no changes to the definition based on the comment, as 
we believe a licensed veterinarian is generally best qualified to 
determine specific treatment plans. We note that we proposed in Sec.  
11.14(b)(5) that an expected length of treatment be included as part of 
the veterinary record that is to be maintained by event management. All 
such treatment plans are subject to APHIS review, in order to determine 
whether the plans include the use of substances or practices to cause 
or mask soring.
    A few commenters asked that we include ``and such therapeutic 
practices cannot supersede what is allowed within the HPA'' to the end 
of the definition.
    We are adding no such change to the definition because it is 
unnecessary. The regulations are limited to what is required or 
permitted in the Act and do not supersede it.

Prohibitions Concerning Exhibitors

    Current Sec.  11.2, ``Prohibitions concerning exhibitors,'' lists 
general and specific prohibitions for any device, method, practice, or 
substance used on any horse at any horse show, horse exhibition, horse 
sale, or horse auction if such use causes or can reasonably be expected 
to cause such horse to be sore. We are moving those prohibitions from 
Sec.  11.2 to revised Sec.  11.6 and reserving Sec.  11.2 in the 
regulations for future use. No commenters took issue with our proposal 
to move the prohibitions to another section and reserve Sec.  11.2.

Non-Interference With APHIS Representatives

    Current Sec.  11.3 contains the ``scar rule,'' which refers to the 
presence of certain types of dermatologic conditions on the horse's 
pastern and fore pastern suggesting that a horse has been sored.
    We proposed removing the scar rule from this section. We are 
including a revised version of it in Sec.  11.7, a section which we had 
previously reserved in the proposed rule, under the heading 
``Dermatologic conditions indicative of soring,'' or DCIS. We 
originally proposed to move the revised scar rule to Sec.  11.6(b)(22) 
but determined that it is thematically incompatible with other 
provisions in Sec.  11.6(b). We discuss DCIS at greater length later in 
this document.
    The language we proposed adding to revised Sec.  11.3 prohibits 
persons from assaulting, resisting, opposing, impeding, intimidating, 
threatening, or interfering with APHIS representatives or HPIs, or in 
any way influencing attendees of a horse show, exhibition, sale, or 
auction to do the same. Persons guilty of such violations may be held 
criminally liable and referred to the U.S. Department of Justice for 
prosecution. As we noted in the proposal, this amendment strengthens 
regulatory protections for the safety of both APHIS representatives and 
HPIs appointed by management and engaged in duties at the events 
listed, as well as the safety of horses and attendees. We received no 
comments specifically addressing this revision and are finalizing as 
proposed.

Owners, Trainers, Exhibitors, Custodians, Transporters, and Any Other 
Disqualified Person

    Section 11.4 of the current regulations includes requirements 
regarding inspection of horses by APHIS representatives, as well as 
detention of horses for inspection if an APHIS veterinarian has 
probable cause to

[[Page 39204]]

believe that a horse is sore. We proposed revising Sec.  11.4 to 
include provisions regarding the status of persons whom USDA has 
disqualified from showing, exhibiting, selling, or auctioning horses. 
Provisions for inspection and detention of horses, which currently 
comprise this section, have been moved to proposed Sec.  11.8.
    The text we proposed for revised Sec.  11.4 requires that any 
person disqualified from participating in any horse show, exhibition, 
sale, or auction shall not show, exhibit, or enter any horse, directly 
or indirectly through any agent, employee, corporation, partnership, or 
other device, and shall not judge, manage, or otherwise participate in 
events covered by the Act within the period during which the 
disqualification is in effect. We received no comments specifically on 
this change and are finalizing this provision to prevent disqualified 
persons from continuing to participate in shows and other events either 
directly or indirectly through the aid of other identities or persons.

Appeal of Inspection Report

    Section 11.5 currently requires the management of any horse show, 
horse exhibition, horse sale, or horse auction to provide APHIS 
representatives with unlimited access to the grandstands and all other 
premises of any horse show, exhibition, or horse sale or auction, 
including any adjacent areas under their direction, for the purpose of 
inspecting horses or records. Management must also provide an adequate, 
safe, and accessible area for the visual inspection and observation of 
horses. This section also requires persons having custody of any horse 
at any horse show, exhibition, or horse sale or auction to admit any 
APHIS representative or DQP appointed by management to all areas of 
barns, compounds, horse vans, horse trailers, stables, or other grounds 
or related areas at any horse show, exhibition, or horse sale or 
auction, for the purpose of inspecting any such horse at reasonable 
times.
    We proposed moving these provisions for access to premises and 
records to a new Sec.  11.9 and changing the heading of Sec.  11.5 to 
read ``Appeal of inspection report.'' In the proposed rule, we proposed 
to revise Sec.  11.5 to provide that any horse owner, trainer, 
exhibitor, custodian, or transporter may appeal inspection report 
findings all or in part to the Administrator. We also proposed that the 
appeal would require a written statement contesting the inspection 
finding(s) as well as any documentation or other information in support 
of the appeal. We proposed that the appeal would have to be received by 
the Administrator, preferably by electronic mail, or by U.S. mail, 
within 21 business days of receipt of the inspection report. The 
Administrator would then send a final decision to the person requesting 
the appeal.
    Several commenters addressed this proposed provision. One commenter 
stated that ``inspection report'' is not a defined term in the proposed 
rule.
    As discussed below, the term does not appear in the revised 
regulations and thus does not need to be defined in this final rule. 
With that being said, to address the comment for the purposes of the 
proposed rule, we would define an inspection report as a report that 
details the finding resulting from an inspection to determine 
compliance with the Act and regulations. Any alleged noncompliances of 
the Act or regulations found as a result of the inspection would have 
been noted in the report.
    A few commenters supporting the proposed rule stated that appeals 
should only apply to adjudicated cases, not inspection reports, adding 
that the current regulations [Sec.  11.25] require HIOs to provide a 
process to appeal penalties resulting from inspections--not the results 
of the inspections themselves. One commenter stated that if a horse is 
found sore under the proposed regulations and disqualified without 
prosecution or penalty, there should be no appeal.
    The Act directs the Secretary not to assess a penalty or issue a 
cease-and-desist order without giving parties the right to appeal and 
opportunity to a hearing. There will be no civil penalties assessed 
without notice and an opportunity for a hearing, and all noncompliances 
will be subject to enforcement by the Department. As explained below, 
we have amended proposed Sec.  11.5 so that it addresses due process 
and provides for appeal of a disqualification.
    A commenter stated that the removal of the regulatory role of HIOs 
leaves no recourse or appeal for a determination of violation and 
appears to permit an appeal only if USDA determines there is ``probable 
cause'' to do so, meaning it passes an absolute judgment upon its own 
decision and imposes a 21-day limitations period on any appeal. The 
commenter added that by imposing a 21-day deadline, USDA would now 
require owners and trainers to challenge every disqualification or risk 
having USDA later argue that any such challenge was waived.
    Though unclear, the commenter's mention of ``probable cause'' is 
apparently in reference to the provision for re-inspection of detained 
horses under proposed Sec.  11.8(h), in which an alleged violator may 
request re-inspection and testing of a horse provided that the request 
is made to APHIS ``immediately after the horse has been examined by 
APHIS representatives,'' and that ``an APHIS representative determines 
that sufficient cause for re-inspection and testing exists.'' The 21-
day limitation period referenced by the commenter applies to appeal of 
the inspection report under proposed Sec.  11.5. As discussed below, 
the two are distinct processes, and, under the terms of the proposed 
rule, a party could file an appeal to contest an inspection report 
regardless of whether re-inspection was requested or not.
    The intent of proposing appeal of an inspection report under Sec.  
11.5 was to explore potential options to provide parties with a 
recourse to appeal disqualification, including possible options to 
resolve disputes before the show takes place. The 21 days permitted for 
an appeal gives time for the alleged violator to prepare an appeal, 
although the individual can choose to submit the appeal of 
disqualification at any point up to 21 days. We did not consider it 
likely that an alleged violator would appeal the inspection report 
unless they had been disqualified. With that being said, the commenter 
is correct that, under the specific terms of the proposed rule, there 
was no direct recourse for appeal in the proposed rule following a 
determination resulting in a disqualification. Moreover, for purposes 
of due process, it is the disqualification itself, rather than the 
inspection report, for which we think appeal should be afforded.
    To address this matter, we are revising proposed Sec.  11.5 to 
provide for appeal of the disqualification itself, rather than the 
inspection report. As revised, it provides that any horse owner, 
trainer, exhibitor, custodian (or any other person responsible for 
entering the horse in an event), or transporter may appeal to the 
Administrator for a decision on whether a disqualification decision 
concerning a horse at a horse show, horse exhibition, horse sale, horse 
auction, or other covered event was justified. There may only be one 
appeal per disqualified horse per event; however, all parties with 
interest in the disqualification may contribute to the appeal. (This 
will preclude duplicative appeals and help focus agency resources on 
expeditious evaluation of the appeals received.) To appeal, the horse 
owner, trainer, exhibitor, custodian, or transporter must send a 
written statement contesting the disqualification and include any

[[Page 39205]]

documentation or other information in support of the appeal. To receive 
consideration, the appeal must be received by the Administrator, 
preferably by electronic mail, to <a href="/cdn-cgi/l/email-protection#2d45425f5e485d5f4259484e594442436d585e494c034a425b"><span class="__cf_email__" data-cfemail="88e0e7fafbedf8fae7fcedebfce1e7e6c8fdfbece9a6efe7fe">[email&#160;protected]</span></a> within 21 
days of the date the horse owner, trainer, exhibitor, custodian or 
transporter received the disqualification that is the subject of the 
appeal. In addition, we are adding an avenue to request expedited 
review. If expedited review of the appeal is requested, this must be 
noted as such, and information in support of this request must 
accompany the appeal so that APHIS may ascertain whether expedited 
review is warranted. The Administrator will send a final decision, in 
writing via either electronic mail or postal mail, to the person 
requesting the appeal as promptly as practicable. Additionally, the 
above-mentioned provision for re-inspection in proposed Sec.  11.8(h), 
in which an alleged violator may request re-inspection of a horse, 
addresses due process concerns to some degree by giving the violator an 
imminent opportunity to appeal a disqualification resulting from 
inspection in the field. However, the re-inspection is contingent on 
whether the inspector determines that sufficient cause exists for doing 
so. If the horse passes a re-inspection before the show, there is no 
disqualification based on inspection results. If the horse fails the 
re-inspection, the disqualification stands, and the alleged violator 
may appeal through the process in Sec.  11.5.
    The same commenter stated that forcing owners and trainers to 
challenge every disqualification on a purportedly inadequate record 
does not comport with due process or allow them to be heard in a 
meaningful manner. The commenter added that to comport with due 
process, USDA must require any disqualification to be supported by 
adequate evidence and documentation by requiring the inspector to 
document and provide photographic evidence of any ``dermatologic 
conditions,'' and allowing an owner or trainer to photograph or film an 
inspection in order to raise challenges to that inspection at a later 
date.
    APHIS representatives and HPIs are required to document 
noncompliant dermatologic conditions, as well as any other indications 
of noncompliance.\22\ As the commenter correctly stated, due process 
involves providing the custodian of the horse adequate notice of the 
basis for the disqualification as soon as practicable and prior to the 
deadline to appeal. We will do so by providing the inspection report to 
the custodian following the disqualification so that, prior to leaving 
the event, they have the information necessary to mount an appeal based 
on dispute of material fact. With that being said, owners and trainers 
are free to record inspections from a position outside the inspection 
area.
---------------------------------------------------------------------------

    \22\ APHIS representatives and other qualified persons prepare 
this documentation as part of fulfilling the notification 
requirement for reporting sore horses to management in accordance 
with section 4 of the Act (15 U.S.C. 1823(b)). The Horse Protection 
program also internally requires that such documentation be prepared 
and maintained for reporting and enforcement purposes by APHIS 
representatives and qualified persons inspecting horses.
---------------------------------------------------------------------------

    One commenter stated that a fundamental tenet of due process 
requires that parties receive fair notice of the specific standards by 
which they are being deprived of any property interest. On this point, 
they stated that the standards for an HPA violation under the existing 
regulations and the proposed rule are vague and fail to provide 
adequate notice, particularly the revised scar rule's reference to 
``dermatologic conditions.''
    We disagree that the regulations do not provide persons with 
knowledge of what might constitute a violation, including with respect 
to dermatologic conditions. The prohibitions on particular action 
devices, types of pads and wedges, and substances are clear and 
unambiguous. Likewise, under the regulations as revised in this final 
rule, dermatologic conditions cannot be any conditions whatsoever, but 
only those that an HPI or APHIS representative determines to be 
indicative of soring as that term is defined in the statute, including 
irritation, moisture, edema, swelling, redness, epidermal thickening, 
and loss of hair (patchy or diffuse). Moreover, following the 
disqualification, the HPI or APHIS representative will disclose the 
specific basis for the disqualification through issuance of an 
inspection report and the party involved may contest the 
disqualification through appeal.
    A commenter asked us what happened to the provisions in current 
Sec.  11.25, particularly in light of a discrepancy between the 
preamble and the regulatory text. The preamble had stated that the 
regulatory text of the proposed rule contained a parallel process in 
Sec.  11.5 ``for alleged violators to appeal penalties resulting from 
inspections conducted by APHIS representatives or HPIs appointed by 
management,'' yet the regulatory text contained no such parallel 
process.
    The provisions in Sec.  11.25 give authority to HIOs to establish 
and enforce minimum penalties for violators. Because we proposed to 
relieve HIOs of all regulatory roles and responsibilities under the 
HPA, there was no longer a need for the provisions in that section. 
With regard to the discrepancy between the preamble and the regulatory 
text, we initially intended to draft a separate process to establish 
and enforce minimum penalties for violators, as well as the right for 
violators to contest any attempt to enforce such penalties. Later on, 
during development of the proposed rule, we determined that the 
existing right to a hearing provided for in the Act, the process for 
which is described in 7 CFR part 1, contains such a process, and that a 
separate process would be duplicative and potentially confusing. The 
regulatory text of the proposed rule reflects the Agency's intent.
    With that being said, as noted above, we are explicitly providing 
for appeal of disqualification under Sec.  11.5 in this final rule.
    In 2016, we published a separate proposed rule to revise the HPA 
regulations in the Federal Register (81 FR 49112-49137, Docket No. 
APHIS-2011-0009). In response to the 2016 proposal, several commenters 
submitted due process concerns over reviews of pre-show inspection 
findings of soring and subsequent disqualification from showing. Some 
commenters at the time requested that we develop a pre-show process 
whereby owners and trainers may contest and seek immediate review of a 
finding that a horse is sore. They also suggested that when USDA 
diagnoses a horse as sore after initially being passed by a DQP, the 
horse should be allowed to be shown until there is a final decision in 
the matter, i.e., until due process is completed.
    We suggested in the proposal to this final rule that one possible 
solution involves conducting pre-show inspections far enough in advance 
of the exhibition or show to allow for an opportunity to be heard 
before the event. A key problem with this solution, however, is that 
the farther in advance of a show that an inspection takes place, the 
more time there is to sore a horse after the inspection and before the 
show. Monitoring protocols would need to be developed and staffed to 
ensure horses are not sored following inspection. Moreover, under the 
current event structure, there is insufficient time to conduct a review 
process between the inspection and the horse being exhibited or shown, 
and it would require a significant change in show and exhibition 
practices, and possible restructuring of the industry itself, to allow 
such a process to take place. It

[[Page 39206]]

would also entail deploying more inspectors to shows and developing 
monitoring protocols to ensure horses are not sored following 
inspection.
    We acknowledged in the proposal that there may be other means of 
addressing the issue and requested public comment regarding other 
alternatives to a pre-show review process, including consideration of 
regulatory bodies, statutory authorities, or incentives and 
disincentives, including withholding or forfeiture of prize money. To 
determine the feasibility of a pre-show inspection and review, we asked 
for comments addressing the particulars of such a review, including 
where and when the pre-show inspection might be conducted, how 
monitoring of horses after inspection would take place to prevent 
tampering, and what parties should be involved in the review process.
    We received several comments supporting and opposing a pre-show 
inspection that would allow for reviews of soreness findings.
    Most commenters addressing this subject agreed that such a review 
is not feasible under the way that shows are currently conducted. 
Several commenters stated that it is not possible to adjudicate in the 
limited timeframe between examining a horse and competition, with one 
adding that the point is to have qualified inspectors undertaking 
examinations and not finding ways to override their findings. Another 
commenter stated that it is unacceptable to propose that the findings 
of a qualified, unbiased professional inspector should be challenged 
and overridden in the moment at an event. The commenter added that the 
HPA requires that a horse in violation must be prohibited from being 
shown, and that any delay in or failure to invoke this prohibition 
would be in violation of the Act. One commenter opined that concerns 
about due process originated in the conflicts seen when a DQP would 
`pass' a horse and the APHIS inspector would subsequently `fail' the 
horse as sored, and that with abolishment of the DQP program and the 
use of only inspectors screened and authorized by APHIS, a pre-show 
review to resolve such conflicts would be unnecessary.
    We agree with commenters that it is not feasible to adjudicate in 
the limited timeframe between examining a horse and competition; we did 
not receive comments that suggested alternative show practices that 
would make a pre-show review process practicable. The HPA prohibits 
showing or exhibiting horses determined as sore from showing, with a 
litigation risk inherent in allowing horses that may be sore to show. 
Also, the longer the interval between an inspection and the event, the 
more opportunity there is to sore a ``cleared'' horse. As we indicated 
in our recent proposal, section 4 (15 U.S.C. 1823(a)) of the HPA vests 
in management the responsibility to disqualify or prohibit a horse from 
being shown, exhibited, sold, or auctioned following a determination by 
an inspector that the horse is sore. Specifically, the statute and 
regulations require management to (among other actions) disqualify a 
horse in instances where (1) the horse is sore or (2) management is 
notified by a DQP or APHIS representative that the horse is sore. 
Further, section 5 (15 U.S.C. 1824) requires that management disqualify 
such horses by listing the failure to do so as an ``unlawful act.'' 
Because of these statutory considerations, and because commenters could 
not provide a meaningful way to allow for a pre-show hearing following 
an inspection resulting in disqualification, we consider the appeals 
process in this final rule, which allows for prompt post-
disqualification appeal, due process regarding the deprivation caused 
by disqualification. Further, the re-inspection provision in proposed 
Sec.  11.8(h) addresses due process concerns to some degree by giving 
an alleged violator an opportunity to appeal a disqualification 
resulting from inspection in the field provided sufficient cause for 
doing so is determined by an APHIS representative. If a horse passes a 
re-inspection before the show, there is no disqualification based on 
inspection results.
    A commenter opposed to the proposed rule stated that under the 
current system, horse owners have no right to raise a challenge and 
have their horses shown if they are disqualified before a show, and 
that the rule offers no solution to this problem. The commenter stated 
that to address due process concerns with its enforcement efforts, USDA 
must begin by looking at other breeds covered under the HPA and 
consider an objective inspection system that utilizes blood testing, 
urinalysis, thermography, x-rays/radiology, and gas chromatography-mass 
spectrometry. The commenter further recommended that the program be 
overseen by an independent inspection entity under the current HIO 
structure or through some other new structure as is currently allowed 
in other breed programs.
    These comments do not offer a workable solution. No such tests 
listed by the commenter can definitively rule out that a horse has been 
sored, and the commenter discounted a determination of soring by a 
trained inspector who has palpated the horse and found sensitivity to 
be present. As we stated above, the NAS study considered this part of 
the inspection protocol to be the ``gold standard'' for detecting local 
pain and inflammation.\23\ It is also worth noting that one commenter 
stated that the practice of disqualifying a horse based on an adverse 
inspection finding (i.e., not allowing the horse to be shown/
exhibited), with appeals possible after the fact, is consistent with 
what is done in other breeds. To that end, we note that one of the 
commenter's suggestions would entail retention of the regulatory 
functions of HIOs, which, for reasons discussed in the proposed rule 
and this final rule, we are abolishing.
---------------------------------------------------------------------------

    \23\ NAS study, page 46.
---------------------------------------------------------------------------

    Finally, we note that the commenter failed to address critical 
details regarding how any pre-show review process could achieve the 
statutory prohibition against showing sored horses. Details that the 
commenter did not address in their recommendation include where and 
when the inspection should take place if a pre-show review process will 
be afforded, who should be physically present for the review process, 
and how the health and safety of the horse should be monitored after 
the inspection to make sure the horse is not subsequently sored while 
review is ongoing. Because of these deficiencies, and in light of the 
foregoing considerations that counsel against pre-show review 
processes, we do not consider the commenter to have provided a 
meaningful recommendation to afford pre-deprivation due process.
    One commenter asked who would be appointed to a pre-show review 
process, noting that reviewers would have to be on site in addition to 
the inspectors, and wanted to know how APHIS would fill the gap.
    We cannot answer the commenter's question as to whom we would 
appoint, as we only asked for comments about the feasibility of 
establishing such a review process.
    We also asked how a pre-show review process might implicate or 
interact with the re-inspection process currently located in Sec.  
11.4(h), which we are revising and moving to new Sec.  11.8(h). As we 
note above, this re-inspection provision provides a pre-show means to 
appeal an initial disqualifying inspection in the field by requesting a 
second inspection provided that sufficient cause for reinspection 
exists and an APHIS representative is available to perform the re-
inspection. If a re-inspection is granted and the horse

[[Page 39207]]

passes, there is no disqualification based on inspection results. We 
received no comments specifically on this point.
    Finally, a few commenters provided specific ideas for 
disincentivizing soring, as we requested. One commenter suggested that 
any horse found to be sore not be allowed to show for 6 months. The 
commenter also recommended making the offspring of a horse found to be 
sore more than one time ineligible for breed registration, as well as 
not allowing a sore horse to be sold for 2 years after diagnosis, which 
would reduce the value of such horses and disincentivize soring.
    We think this final rule is adequate to disincentivize soring. 
Therefore, we do not think the measures proposed by the commenter, even 
if they fall within the bounds of the Act, are necessary.
    A commenter suggested that the Act be strengthened by fining 
violators $5,000 for the first offense, $25,000 for the second, 
$150,000 for the third, and taking the horse in question for a fourth 
offense.
    We are making no change in response to the commenter's suggestion. 
Penalties are enshrined in the Act and require Congressional action to 
change.
    Another commenter asked why the rule does not include the 
imposition of extended disqualification periods, up to and including 
lifetime disqualifications, and to consider including extended 
disqualification periods for sore horses or offenders with multiple 
violations.
    These periods are listed in the Act and cannot be changed without 
an act of Congress.

Prohibitions To Prevent Soring

    Current Sec.  11.2, ``Prohibitions concerning exhibitors,'' 
contains general and specific prohibitions on certain devices, methods, 
practices, or substances used on any horse at any horse show, horse 
exhibition, horse sale, or horse auction covered under the Act. These 
current prohibitions already include prohibitions intended specifically 
for Tennessee Walking Horses and racking horses regarding substances 
and duration of workouts in paragraphs (c) and (d) respectively.
    We proposed to revise Sec.  11.6 and retain the current Sec.  11.2 
heading ``Prohibitions concerning exhibitors.'' As with current Sec.  
11.2, revised Sec.  11.6 lists general and specific prohibitions on 
certain devices, methods, and practices used on any horse at any horse 
show, horse exhibition, horse sale, or horse auction. We also proposed 
to include new prohibitions in Sec.  11.6(c) specific to Tennessee 
Walking Horses and racking horses.

General Prohibitions

    Current paragraph Sec.  11.2(a) contains a general prohibition on 
the use of any device, method, practice, or substance on any horse at 
any horse show, exhibition, sale, or auction if that use causes or can 
reasonably be expected to cause a horse to be sore.
    We proposed in Sec.  11.6(a) to include a similar general 
prohibition on the use of any device, method, practice, or substance. 
We also proposed adding a provision under the general prohibitions 
prohibiting the use on a horse of any device, method, practice, or 
substance that masks soring.
    Under section 5 (15 U.S.C. 1824(7)) of the Act, APHIS has the 
authority to prohibit any equipment, device, paraphernalia, or 
substance that a horse is wearing or bearing which the Secretary by 
regulation under section 9 (U.S.C. 1828) of the Act prohibits to 
prevent the soring of horses. USDA considers prohibiting items and 
substances that mask soring to be essential in helping to prevent the 
soring of horses, as masking can impede efforts to detect soring 
through inspections. APHIS currently considers the use of substances to 
mask soring as a violation of the Act and regulations and conducts 
enforcement accordingly. Our addition of the prohibition on masking in 
the general prohibitions is intended to underscore what the Act already 
prohibits. (We also proposed prohibiting lubricating substances.)
    As masking typically involves the use of substances, including 
lubricants, we address comments relating to masking below under 
``Lubricants.''

Prohibited Devices, Equipment, and Practices

    Paragraph (b) of current Sec.  11.2, ``Specific prohibitions,'' 
prohibits on any horse the use of certain devices, methods, practices, 
and substances at any covered horse show, exhibition, sale, or auction. 
Under the current regulations, some restricted uses are permitted 
provided they do not exceed the specifications accompanying each.
    In proposed Sec.  11.6(b), ``Prohibited devices, equipment, and 
practices,'' we similarly list devices, equipment, and practices that 
are prohibited on any horse at a horse show, horse exhibition, horse 
sale, or horse auction, including Tennessee Walking Horses and racking 
horses. We address specific comments we received on the list below.
    We noted in the proposal that Sec.  11.6(b) will continue to allow 
breeds other than Tennessee Walking Horses and racking horses to use 
certain rollers, chains, and bell boots weighing 6 ounces or less, as 
well as pads that elevate or change the angle of hooves 1 inch or less 
at the heel, and certain toe extensions, shoes, and metal hoof bands. 
Except for Tennessee Walking Horses and racking horses, for which all 
action devices are prohibited under proposed paragraph (c)(1), we also 
proposed in paragraph (b) to continue to allow the use of an action 
device on each limb of a horse if the device weighs 6 ounces or less.
    As proposed, we are moving from current Sec.  11.2 to Sec.  
11.6(b)(1) the provision prohibiting more than one action device 
permitted under this section on any limb of a horse. We did not receive 
comments specific to that change and are finalizing as proposed.
    In paragraph (b)(2), we are moving from current (b)(1) the 
prohibition on all beads, bangles, rollers, and similar devices, with 
the exception of rollers made of lignum vitae (hardwood), aluminum, or 
stainless steel, with individual rollers of uniform size, weight and 
configuration, provided each such device may not weigh more than 6 
ounces, including the weight of the fastener. We did not receive 
comments specific to that provision and are finalizing as proposed.
    In paragraph (b)(3), we are moving from current Sec.  11.2(b)(2) 
the prohibition on chains weighing more than 6 ounces each, including 
the weight of the fastener. We did not receive comments specific to 
this provision and are finalizing as proposed. (We received comments on 
the prohibition of chains and chain weights pertaining to Tennessee 
Walking Horses and racking horses, which we address under ``Action 
Devices, Pads, and Wedges'' below.)
    In paragraph (b)(4), we are moving from current Sec.  11.2(b)(3) 
the prohibition on chains with links that are not of uniform size, 
weight, and configuration and chains that have twisted links or double 
links. We did not receive comments specific to that provision and are 
finalizing as proposed.
    In paragraph (b)(5), we are moving from current Sec.  11.2(b)(4) 
the prohibition on chains that have drop links on any horse that is 
being ridden, worked on a lead, or otherwise worked out or moved about. 
We did not receive comments specific to that provision and are 
finalizing as proposed.
    In paragraph (b)(6), we are moving from current Sec.  11.2(b)(6) 
the prohibition on chains or lignum vitae, stainless steel, or aluminum 
rollers which are not smooth and free of protrusions, projections, 
rust, corrosion, or rough or sharp edges. We did not receive

[[Page 39208]]

comments specific to that provision and are finalizing as proposed.
    In paragraph (b)(7), we are moving from current Sec.  11.2(b)(7)(i) 
the prohibition on boots, collars, or any other devices, with 
protrusions or swellings, or rigid, rough, or sharp edges, seams or any 
other abrasive or abusive surface that may contact a horse's leg. We 
did not receive comments specific to that provision and are finalizing 
as proposed.
    In paragraph (b)(8), we are moving from current Sec.  
11.2(b)(7)(ii) the prohibition on boots, collars, or any other devices 
that weigh more than 6 ounces, except for soft rubber or soft leather 
bell boots and/or quarter boots that are used as protective devices. We 
did not receive comments specific to that provision and are finalizing 
as proposed.
    In paragraph (b)(9), we are moving from current Sec.  11.2(b)(8) 
the prohibition on pads or other devices on horses up to 2 years old 
that elevate or change the angle of such horses' hooves in excess of 1 
inch at the heel. While we received many comments on the prohibition of 
pads on Tennessee Walking Horses and racking horses, we did not receive 
comments on this specific provision as it pertains to Sec.  11.2(b) and 
are finalizing as proposed.
    In paragraph (b)(10), we are moving from current Sec.  11.2(b)(9) 
the prohibition on any weight on horses up to 2 years old, except a keg 
or similar conventional horseshoe, and any horseshoe on horses up to 2 
years old that weighs more than 16 ounces.
    Some commenters stated that USDA should prohibit weighted shoes on 
any Tennessee Walking Horses and racking horses at covered events 
because they can increase the potential for injury in the form of 
tissue damage or overexertion of the musculature. One commenter 
cautioned against an outright prohibition on weighted shoes, noting 
that all horseshoes have weight, and proposed a maximum shoe weight 
limit of 16 ounces, while other commenters suggested setting a similar 
shoe weight limit for all horses. Another commenter stated that some 
Tennessee Walking Horses are wearing shoes made from metals heavier 
than steel or iron, and that the heavier shoes are inducing soring even 
in horses in flat-shod classes. To prohibit the use of heavier metals 
for shoes, some commenters recommended that the shoes required for 
horses of all ages be made completely of rubber, plastic, aluminum, or 
steel. On the other hand, some commenters asked that we continue to 
allow heavy shoes for horses that tend to be overly ``pacey.''
    We are finalizing as proposed. While we limit shoe weights on 
horses up to 2 years old to 16 ounces or less, there is no scientific 
literature that we are aware of on which we can base a prohibition on 
shoes weighing more than 16 ounces on older horses at this time. 
Therefore, we are not including a weight limit on shoes for horses 2 
years and older. We are actively collecting data on the usage and 
effects of shoes weighing more than 16 ounces on horses and will 
consider prohibiting such shoes in a future rulemaking, if warranted.
    Another commenter stated the proposed rule is insufficient because 
it allows the use of ``a keg or similar conventional horseshoe'' 
without a weight limitation.
    The proposed provision in paragraph (b)(10) actually limits 
horseshoe weights on horses up to 2 years old to 16 ounces or less, 
which includes a ``keg or similar conventional horseshoe.'' However, to 
ensure that the provision is clear on this point we are including the 
words ``that weighs 16 ounces or less'' after the words ``keg or 
similar conventional horseshoe.''
    Many commenters asked that hoof bands and any weight attached to 
the hoof or horseshoe (other than a keg or similar conventional 
horseshoe itself, including the allowable caulk and any studs or 
material used on the bottom of the shoe for traction) weighing more 
than 16 ounces should be prohibited on horses of any age in the three 
breeds known to be subjected to soring. We are not making any changes 
to the regulations regarding hoof bands or horseshoe weights. 
Horseshoes are not a prohibited item and hoof bands, when used in 
accordance with proposed paragraph (b)(17), can serve to secure the 
shoe to the hoof. As we note above, we continue to collect data on the 
effects of shoes weighing more than 16 ounces on horses.
    A commenter stated that if USDA allows heavy shoes, it should 
require management to inform APHIS if heavy shoes will be permitted at 
a show (extending Sec.  11.16(a)(7) accordingly).
    Proposed Sec.  11.16(a)(7) requires that management contact APHIS 
if they plan to allow any horse to be shown, exhibited, or sold 
undergoing therapeutic treatment with any of the items otherwise 
prohibited in Sec.  11.6. The proposed regulations do not consider 
shoes weighing more than 16 ounces on horses 2 years old and older to 
be a prohibited item. We are not making a change to the regulations 
that would require management to inform APHIS if they plan to allow 
heavy shoes because absent such a prohibition, we do not expect any 
show to prohibit such shoes. We continue to gather information on the 
effects of shoes weighing more than 16 ounces and will consider future 
limitations on such shoes if we determine their prohibition is 
necessary to prevent the soring of horses.
    The same commenter added that whether or not management plans to 
allow horses to wear pads or wedges, if they plan to allow the use of 
heavy shoes on horses, a farrier should be required to be present or on 
call to pull a shoe for inspection if called for by an APHIS 
representative or HPI.
    The farrier requirement stands for any horse show that has 
appointed an APHIS representative or HPI to conduct inspections, as 
even horses wearing shoes that are not heavy may need to have a shoe 
pulled upon request of an inspector to check for conditions such as 
pressure shoeing. A trained farrier's presence is important because 
only a farrier can safely remove or replace shoes on a horse.
    Several commenters cited possible problems with shoe width impeding 
proper inspection of the horse's hooves. Some commenters recommended a 
requirement that shoe dimensions cannot exceed 1\1/2\ inches wide by 
\1/2\ inch thick and cannot obstruct the use of hoof testers on the 
sole and frog, and one suggested that APHIS adopt language from other 
breed disciplines by adding to the provision ``the sole and entire frog 
of the foot must be visible.''
    We are not setting specific dimension requirements on shoes because 
we reviewed research available regarding horseshoe dimensions and did 
not determine there was sufficient evidence to justify any restrictions 
at this time. APHIS will collect data regarding the use of these shoes 
and consider horseshoe dimension restrictions in a future rulemaking if 
we determine they are necessary to prevent the soring of horses. We 
note that APHIS may examine or require that a shoe be removed at any 
time if necessary to determine if a horse is sore.
    In paragraph (b)(11), we are moving from current Sec.  11.2(b)(10) 
the prohibition on artificial extension of the toe length, whether 
accomplished with pads, acrylics, or any other material or combinations 
thereof, that exceeds 50 percent of the natural hoof length, as 
measured from the coronet band, at the center of the front pastern 
along the front of the hoof wall, to the distal portion of the hoof 
wall at the tip of the toe. The artificial extension must be measured 
from the distal portion of the hoof wall at the tip of the toe at a 90-

[[Page 39209]]

degree angle to the proximal (foot/hoof) surface of the shoe.
    Some commenters stated that, if they are to remain, recommended toe 
extensions should be within the limit of 50 percent of the natural hoof 
length as measured from the hairline of the hoof capsule to the center 
of the front pastern along the front of the hoof wall to the distal 
portion of the hoof wall at the tip of the toe. One commenter 
recommended that the maximum toe length be 4\1/2\ inches, including the 
thickness of the shoe, measured as specified in United States 
Equestrian Federation (USEF) General Rule 510.\24\
---------------------------------------------------------------------------

    \24\ To view General Rule 510, go to <a href="https://www.usef.org/forms-pubs/s9SeSv4S0Sc/gr--general-rules">https://www.usef.org/forms-pubs/s9SeSv4S0Sc/gr--general-rules</a>.
---------------------------------------------------------------------------

    We are finalizing as proposed. To make a determination about the 
specific lengths recommended by commenters, we will require more 
research on artificial toe lengths used for other horse breeds, most of 
which are regulated under USEF.
    Another commenter stated that allowing toe extensions in proposed 
Sec.  11.6(b)(11) is open to abuse because ``natural hoof length'' can 
be manipulated to far exceed ideal hoof length, and then a further toe 
extension is permitted beyond that. The commenter added that artificial 
toe extensions should be prohibited entirely.
    We assume the commenter's concern is not with the provision as 
applied in Sec.  11.6(b)(11), but with artificial toe extensions and 
soring in Tennessee Walking Horses and racking horses, insofar as 
soring is rarely practiced and confers no competitive advantage to 
horses that do not practice the ``big lick'' step in Performance 
division events. We note that all artificial toe extensions will be 
prohibited on any Tennessee Walking Horse or racking horse unless such 
horse has been prescribed and is receiving therapeutic treatment as 
approved in writing by a licensed veterinarian. However, even if a 
Tennessee Walking Horse or racking horse is wearing artificial toe 
extensions under a therapeutic exemption, the toe extension cannot 
exceed the restrictions for all horses in Sec.  11.6(b)(11) and (12) of 
this final rule. To the commenter's point, regulations cannot prescribe 
``ideal'' hoof length, but a prohibition of all toe extensions unless 
therapeutically required can be considered in a future rulemaking if 
evidence arises that supports such a prohibition in other horse breeds.
    In paragraph (b)(12), we are moving from current Sec.  11.2(b)(11) 
the prohibition on toe length that does not exceed the height of the 
heel by 1 inch or more. The length of the toe must be measured from the 
coronet band, at the center of the front pastern along the front of the 
hoof wall to the ground. The heel must be measured from the coronet 
band, at the most lateral portion of the pastern, at a 90-degree angle 
to the ground, not including normal caulks at the rear of a horseshoe 
that do not exceed \3/4\ inch in length. That portion of caulk at the 
rear of a horseshoe in excess of \3/4\ of an inch must be added to the 
height of the heel in determining the heel/toe ratio.
    A few commenters stated that caulks exceeding \3/4\ of an inch 
should be prohibited entirely.
    We are finalizing as proposed. We will consider such a prohibition 
in a future rulemaking if evidence is identified supporting such a 
prohibition. As it stands now, caulks exceeding \3/4\ of an inch must 
have the extra height considered in heel/toe ratio measurements.
    In paragraph (b)(13), we are moving from current Sec.  11.2(b)(12) 
the prohibition on pads that are not made of leather, plastic, or a 
similar pliant material. While we received numerous comments regarding 
the prohibition on pads for Tennessee Walking Horses and racking 
horses, we received none that opposed our moving this specific 
provision to proposed Sec.  11.6(b) and we are finalizing as proposed.
    In paragraph (b)(14), we are moving from current Sec.  11.2(b)(13) 
the prohibition on any object or material inserted between the pad and 
the hoof other than acceptable hoof packing, which includes pine tar, 
oakum, live rubber, sponge rubber, silicone, commercial hoof packing, 
or other substances used to maintain adequate frog pressure or sole 
consistency. We proposed and are adding a prohibition on the use of 
acrylic or other hardening substances as hoof packing.
    A commenter stated that eliminating non-therapeutic pads and wedges 
in proposed Sec.  11.6(c)(3) means that Sec.  11.6(b)(14) should be 
revised to prohibit all objects or materials inserted into the hoof, as 
most hoof-packing materials require a pad to hold them in place.
    We are making no changes in response to the commenter. Certain pads 
continue to be permitted for breeds other than Tennessee Walking Horses 
and racking horses not covered under Sec.  11.6(c). Moreover, pads for 
therapeutic treatment can still be prescribed by a licensed 
veterinarian in accordance with proposed Sec.  11.6(c)(3) for Tennessee 
Walking Horses and racking horses.
    We proposed in paragraph (b)(15) to move from current Sec.  
11.2(b)(14) the prohibition on single or double rocker-bars on the 
bottom surface of horseshoes which extend more than 1\1/2\ inches back 
from the point of the toe, or which would cause, or could reasonably be 
expected to cause, an unsteadiness of stance in the horse with 
resulting muscle and tendon strain due to the horse's weight and 
balance being focused upon a small fulcrum point.
    A commenter asked that we develop a regulatory definition in Sec.  
11.6(b)(15) that clearly distinguishes between permitted shoes and 
prohibited ``non-conventional'' shoes and asked that we include other 
specific types of abusive shoes that APHIS wants to ban in order to 
prevent soring.
    We are finalizing as proposed. Requirements pertaining to shoes are 
addressed in the discussion of Sec.  11.6(b)(10); questions about the 
regulatory status of a specific shoe type can be directed to APHIS.\25\

    We proposed in paragraph (b)(16) to move from current Sec.  
11.2(b)(15) the prohibition on metal hoof bands, such as used to anchor 
or strengthen pads and shoes, if placed less than \1/2\ inch below the 
coronet band. In paragraph (b)(17), we are moving from Sec.  
11.2(b)(16) the prohibition on metal hoof bands that can be easily and 
quickly loosened or tightened by hand, by means such as, but not 
limited to, a wing-nut or similar fastener.
    A commenter asked why an exhibitor is not allowed to correct a 
loose hoof band and re-show.
    We expect exhibitors presenting for inspection to check their horse 
for any compliance issues prior to actually presenting. If after the 
horse has passed inspection and prior to showing the custodian 
identifies that the hoof band has become loose, only then can the band 
be adjusted as needed under the supervision of an HPI authorized by the 
event or an APHIS representative.
    In paragraph (b)(18), we proposed to move from current Sec.  
11.2(b)(17) the prohibition on any action device or any other device 
that strikes the coronet band of the foot of the horse except for soft 
rubber or soft leather bell boots that are used as protective devices. 
We did not receive comments specific to that provision and are 
finalizing as proposed.
    In proposed paragraph (b)(19), we are moving from current Sec.  
11.2(b)(18) the prohibition on shoeing a horse or

[[Page 39210]]

trimming a horse's hoof in a manner that will cause such horse to 
suffer, or can reasonably be expected to cause such horse to suffer 
pain or distress, inflammation, or lameness when walking, trotting, or 
otherwise moving. To this prohibition, we added language not in current 
paragraph (b)(18) prohibiting paring the frog or sole in such a manner 
to cause the pain and distress described above, and prohibiting 
bruising of the hoof or any other method of pressure shoeing.
    A commenter asked if a horse would be considered sore if a farrier 
accidentally trims a hoof too short, or if a ride across hard, rocky 
ground results in an accidental bruise to the sole.
    We are finalizing as proposed. We note that under proposed Sec.  
11.6(b)(19), trimming a horse's hoof in a manner that will cause such 
horse to suffer, or can reasonably be expected to cause such horse to 
suffer pain or distress, inflammation, or lameness when walking, 
trotting, or otherwise moving is prohibited. Also, bruising of the hoof 
or any other method of pressure shoeing is prohibited. Regardless of 
the intent of the farrier, any horse with such injuries entered into an 
event may be considered sore.
    Another commenter stated that in all the APHIS ``violations'' 
issued there is not one pressure shoeing violation, so the 
justification for eliminating the pad on that basis is unfounded.
    We disagree with the commenter about pressure shoeing. Pressure 
shoeing involves either cutting a significant portion of or causing 
significant trauma to a horse's hoof immediately before nailing a shoe 
to the hoof, and can cause or be expected to cause the horse to suffer 
pain or distress when moving. Further, the commenter is incorrect in 
stating there are no pressure shoeing violations. APHIS has issued at 
least one violation, in 2018, for pressure shoeing that is specifically 
a soring violation, but the number of violations issued for pressure 
shoeing is not indicative of its ability to cause pain and suffering in 
horses.
    In paragraph (b)(20), we are moving from current Sec.  11.2(b)(19) 
the prohibition on lead or other weights attached to the outside of the 
hoof wall, the outside surface of the horseshoe, or any portion of the 
pad except the bottom surface within the horseshoe. In addition, pads 
may not be hollowed out for the purpose of inserting or affixing 
weights, and weights may not extend below the bearing surface of the 
shoe. Hollow shoes or artificial extensions filled with mercury or 
similar substances are also prohibited in this paragraph.
    While some commenters specifically asked us to consider prohibiting 
any weight of more than 16 ounces attached to the hoof or horseshoe on 
Tennessee Walking Horses, racking horses, and Spotted Saddle Horses, we 
received no comments specific to other prohibitions of this paragraph 
and are finalizing as proposed. Those comments are addressed under the 
discussion of paragraph (b)(10) above.

Stewarding

    In proposed paragraph (b)(21), we added a prohibition on the use of 
whips, cigarette smoke, or similar actions or paraphernalia to distract 
a horse or to otherwise impede the inspection process during an 
examination, including but not limited to, holding the reins less than 
18 inches from the bit shank.
    The NAS study committee's earlier-cited observation of 61 
inspection videos revealed numerous incidents of stewarding during the 
standing inspection that were not dealt with by the DQP, including 
holding the reins closer than 18 inches from the bit, often just below 
or on the shank. The committee noted that these restraint tactics can 
create a distraction during the palpation procedure by inducing pain in 
the oral cavity.\26\ APHIS' experience in conducting inspections is 
consistent with NAS' observation.
---------------------------------------------------------------------------

    \26\ NAS study, page 49.
---------------------------------------------------------------------------

    A commenter stated it is necessary to hold the reins closer to the 
bit in order to control a horse undergoing palpation, as any flinch or 
movement from the horse will cause it to be turned down. We respond 
that such movements from a horse may indicate pain sensitivity upon 
palpation consistent with soring. An experienced, properly trained 
inspector can distinguish incidental movements of the horse from the 
specific behavioral signs of a pain response. The NAS study discusses 
several such behavioral indications of pain that are evaluated in 
veterinary clinical practice.\27\
---------------------------------------------------------------------------

    \27\ NAS study, pages 54-65.
---------------------------------------------------------------------------

    Another commenter recommended that in the prohibition, ``alligator 
clips'' be inserted after ``smoke,'' adding that a far more detailed 
description of stewarding is needed in the regulations.
    We are making no changes in response to the commenter's 
recommendation, as it is not possible to include an exhaustive list of 
all things that could be used to distract a horse or otherwise impede 
the inspection process. The prohibition of ``other stewarding actions 
or paraphernalia to distract a horse or to otherwise impede the 
inspection process during an examination'' includes alligator clips and 
anything else used to distract a horse or otherwise impede the 
inspection process during an examination.

Prohibitions for Tennessee Walking Horses and Racking Horses

    Under proposed Sec.  11.6(c), we prohibited pads, action devices, 
artificial toe length extension, and lubricants on any Tennessee 
Walking Horse or racking horse at any horse show, horse exhibition, 
horse sale, or horse auction, unless such horse has been prescribed and 
is receiving therapeutic treatment using pads, wedges, toe length 
extensions, or substances as approved in writing by a licensed 
veterinarian in accordance with proposed Sec.  11.14(b).
    The current regulation (Sec.  11.2(b)) prohibits the use of a chain 
or other action device on each limb of a horse if the device weighs 
more than 6 ounces. Therefore, the proposal to prohibit all action 
devices on Tennessee Walking Horses and racking horses under Sec.  
11.6(c)(1) has the effect of extending the existing prohibition to 
action devices weighing 6 ounces or less.
    We also proposed under Sec.  11.6(c)(3) to prohibit all pads and 
wedges on any Tennessee Walking Horse or racking horse at any horse 
show, unless prescribed for therapeutic treatment. Under the existing 
regulations, these horses were allowed to wear pads or wedges that 
elevate the angle of horses' hooves less than 1 inch at the heel. Under 
this proposal, no pads or wedges would be allowed, regardless of 
whether they create an angle less than 1 inch at the heel, unless a 
therapeutic exemption has been obtained.
    In the proposed rule, we provided support indicating that pads, 
wedges, and action devices can, on their own or in conjunction with 
other substances and practices, cause soring. For example, with respect 
to pads, we noted that they can ``cause a horse's foot to strike the 
ground at an unnatural angle'' and ``can also induce pain and soring 
over time.'' (88 FR 56936). We also noted in the proposed rule that the 
``clear majority of horses diagnosed by APHIS representatives and DQPs 
as being sore are Tennessee Walking Horses and racking horses, 
specifically those that participate in pads and action devices in 
certain competitions favoring a high-stepping, accentuated gait,'' that 
is, in competitions in which the use of soring could confer a 
``significant performance advantage'' (88 FR 56937).
    We further stated that, based on our observations and experience, 
including

[[Page 39211]]

``compliance inspections, investigations, enforcement of alleged 
violations, oversight of industry-based inspection programs, and 
outreach to the horse industry . . . a relationship continues to exist 
between the use of certain permitted devices and soring, notably among 
Tennessee Walking Horses and racking horses.'' (ibid). Finally, we 
indicated that this relationship between the use of devices and soring 
is not present in Morgans, American Saddlebreds, and other gaited 
breeds, and indicated that soring is rarely detected in flat-shod 
Tennessee Walking Horses and racking horses.
    In other words, in the proposed rule we advanced two bases for the 
proposed prohibition on the use of pads, wedges, and action devices for 
Tennessee Walking Horses and racking horses: First, that pads, wedges, 
and action devices may, under certain circumstances, and particularly 
in conjunction with other substances and practices, cause soring; and 
second, that the use of pads, wedges, and action devices among 
Tennessee Walking Horses and racking horses is strongly associated with 
soring.
    In the proposed rule, we also proposed under Sec.  11.6(c)(2) to 
prohibit all artificial extension of the toe length in Tennessee 
Walking Horses and racking horses unless a horse has been prescribed it 
for therapeutic treatment. This proposal removes the existing allowance 
for artificial toe extensions on Tennessee Walking horses and racking 
horses that are less than 50 percent of the natural hoof length. We 
explain our rationale for the proposed ban on such artificial 
extensions below, under ``Artificial Toe Extensions.''
    Finally, we also proposed under Sec.  11.6(c)(4) to prohibit the 
application of lubricants above the hoof of any Tennessee Walking or 
racking horse at any horse show, exhibition, sale, or auction, unless 
approved in writing by a licensed veterinarian for therapeutic use. 
Under the current regulations in Sec.  11.2(c), all other substances 
are already prohibited on the extremities above the hoof of any 
Tennessee Walking Horse or racking horse while being shown, exhibited, 
or offered for sale at any horse show, horse exhibition, or horse sale 
or auction. We explain our rationale for the proposed ban on lubricants 
below, under ``Lubricants.''
    Before we discuss the comments we received on the proposed 
prohibitions on pads, wedges, and action devices, we feel it important 
to situate them within the historical context of our administration of 
the HPA regulations over the past 50 years and our knowledge of the 
relationship between pads, wedges, and action devices and the soring of 
horses within the Tennessee Walking Horse and racking horse industry.
    In a 1979 rulemaking,\28\ APHIS stated that ``if the horse industry 
makes no effort to establish a workable self-regulatory program for the 
elimination of sore horses, or if such program is established but does 
not succeed in eliminating the sore horse within a reasonable length of 
time, the Department will give serious consideration to the prohibition 
of all action devices and pads.'' (Then, as now, an unacceptable 
percentage of horses wearing these devices and pads was found to be 
noncompliant with the Act.) Between 1979 and 1982, Auburn University 
School of Veterinary Medicine conducted a study (the ``Auburn study'') 
that evaluated the effects of chronic and acute inflammatory responses 
on the front and hind limbs of horses. That study, which we discuss at 
greater length later in this document, determined that the combined use 
of prohibited substances and chains on the pasterns of horses caused 
lesions, tissue damage, and visible alterations of behavior consistent 
with soring. Finally, in a 1988 rulemaking \29\ to expand the list of 
prohibited devices and equipment on horses, APHIS noted that ``experts 
in the horse industry have advised us that elevating the foot can cause 
an increase in tension in the tendons, which can lead to inflammation. 
A tall pad can also contribute to stresses caused by extra weight on a 
horse's foot. Additionally, elevating only the front feet, as is 
typically done, causes an unnatural angulation of the back and body of 
the horse, and changes the alignment of the shoulder muscles, the 
vertebrae, and the pelvis, all of which are then subject to stress, 
irritation, and inflammation.''
---------------------------------------------------------------------------

    \28\ 44 FR 25172-25184, April 27, 1979.
    \29\ 53 FR 14778-14782, April 26, 1988.
---------------------------------------------------------------------------

    In other words, by 1979 we had identified a correlation between the 
use of action devices and pads and an increased incidence of soring 
within the Tennessee Walking Horse and racking horse industry; by 1982, 
a peer-reviewed third party had identified that chains can, in 
conjunction with other prohibited substances, cause effects consistent 
with soring; and by 1988, we had received expert advice that certain 
uses of pads and wedges can cause soring. As we mentioned above, the 
data cited in tables 1 and 2 of the proposed rule regarding 
noncompliance rates within the industry, which covered only a handful 
of years, must be viewed in the context of the aggregate body of data 
that the Agency has amassed over 50 years of enforcing the HPA. This 
includes the above data.
    As we noted in the proposed rule, we have attempted many solutions 
over the years to address the increased incidence of soring in the 
Performance division of the Tennessee Walking Horse and racking horse 
industry, a division that relies extensively on the pads, wedges, and 
action devices that we proposed to prohibit. Beginning in 2010, APHIS 
undertook several nonregulatory approaches to help the industry improve 
compliance with the Act, among them increased engagement with industry 
groups, inspection workshops for DQPs, and stepped-up APHIS presence at 
certain shows to oversee inspections and check whether disqualified 
persons were participating. From 2017 through 2022, APHIS hosted joint 
training sessions with HIOs to ensure all DQPs received the same 
training.
    Nonetheless, these many attempts at nonregulatory solutions have 
done little to move us toward the statutory goal of eliminating soring, 
and incidents of soring remain statistically elevated in the 
Performance division of the Tennessee Walking Horse and racking horse 
industry, especially when compared to rates of soring noncompliance 
found in inspections of flat-shod Tennessee Walking Horses and racking 
horses. In FY 2022, APHIS VMOs found noncompliances in 34.1 percent of 
the 930 horses they inspected at Performance division events, compared 
to a noncompliance rate of only 1.7 percent of the 357 horses they 
inspected at flat-shod events, in which horses compete without wearing 
pads and action devices. As we note elsewhere in this rule, horses in 
both the Performance and flat-shod divisions are the same breeds, 
frequently come from the same bloodlines, and practice the same gaits. 
What differentiates these horses is the presence or absence of the tall 
pads, wedges, chains, and other action devices used in training and 
exhibition, and the exaggerated gait of Performance division horses.
    Accordingly, after 44 years of attempts to encourage this division 
to address soring without recourse to Federal intervention in the form 
of restrictions and prohibitions, we have reached a point at which it 
is apparent that the prohibitions articulated in the proposed rule, 
along with establishing a corps of third-party inspectors working 
independently of the horse industry and free of conflicts of interest, 
are a necessary recourse to prevent the soring of horses. This 
determination is shared

[[Page 39212]]

by other parties with significant experience in and knowledge of the 
equine industry: The changes to the HPA regulations are supported by 
the American Veterinary Medical Association, the American Association 
of Equine Practitioners, and other major veterinary organizations in 
the United States. The outcome will place the Department in a stronger 
position to achieve the remedial purpose of the HPA, which is to 
prevent and eventually eliminate the abusive practice of soring.
    We received many comments that specifically addressed our creation 
of a separate list of prohibitions under Sec.  11.6(c) exclusively for 
the Tennessee Walking Horse and racking horse breeds.
    Numerous commenters stated that APHIS must extend the list of 
prohibited actions and items specific to Tennessee Walking and racking 
horses in Sec.  11.6(c) to all horse breeds, and Spotted Saddle Horses 
in particular. A smaller number of commenters opposed to the proposed 
rule stated that, by creating a separate list of prohibitions, APHIS is 
unfairly singling out Tennessee Walking Horses and racking horses and 
should be inspecting events featuring other breeds equally.
    We are making no changes to Sec.  11.6(c) regarding the breeds 
covered in that paragraph. Our reasoning for allowing the use of these 
items on some breeds, but prohibiting all such items on Tennessee 
Walking Horses and racking horses, is as follows. We did not state in 
the proposed rule that pads, wedges, action devices, and toe extensions 
are always necessarily and per se associated with soring. While they 
can cause soring, as we stated in the proposed rule, action devices and 
pads are sometimes used for proprioceptive purposes during training of 
Morgans, American Saddlebreds, and other gaited breeds.\30\ If the use 
of action devices and pads always and per se caused soring, we would 
detect soring in those breeds that rely on such devices and pads at a 
rate commensurate with the incidence of soring in the Performance 
division of the Tennessee Walking Horse and racking horse industry. 
However, based on our knowledge of all horse breeds showing or 
exhibiting in the United States, soring in breeds other than Tennessee 
Walking Horses and racking horses is rare.
---------------------------------------------------------------------------

    \30\ Clayton, Hilary, ``Rehabilitation for Horses.'' Paper 
presented at American Association of Equine Practitioners, July 
2014.
---------------------------------------------------------------------------

    We are not contending that soring never occurs in other breeds; for 
instance, soring has been known to occur in the Spotted Saddle Horse 
community. However, the infrequency of soring in that breed does not 
warrant the targeted enforcement that we consider necessary to address 
the dramatically higher incidence of soring detected among Tennessee 
Walking Horses and racking horses, especially those competing in the 
Performance division with tall pads and action devices.\31\
---------------------------------------------------------------------------

    \31\ APHIS inspections at Fox Trotter, Spotted Saddle Horse, 
Rocky Mountain Horse, and Mountain Horse shows between FY 2017 and 
FY 2022 resulted in a noncompliance rate of under 1 percent. The 
overall rate of noncompliance at performance shows featuring 
Tennessee Walking Horses in pads and action devices in FY 2022 was 
34.1 percent.
---------------------------------------------------------------------------

    APHIS will continue to enforce the Act and monitor the instances of 
soring in breeds and classes other than the Performance division of the 
Tennessee Walking Horse and racking industry. However, as we noted in 
the proposed rule and again reiterate, soring imparts little to no 
advantage to competitors at these shows, as the gaits on which most 
breeds are evaluated are noticeably distinct from the exaggerated ``big 
lick'' step featured at Tennessee Walking horses and racking horse 
Performance division events, and events for other breeds do not 
incentivize soring by placing such a premium on the ``big lick'' step.
    A commenter, noting that the proposal states that ``soring in 
breeds other than Tennessee Walking Horses and racking horses confers 
no significant performance advantage and is therefore rarely if ever 
practiced'' stated that this is a blanket assumption that glosses over 
the longstanding problems with the current inspection model and ignores 
that Spotted Saddle horses have been targeted as well. As support, the 
commenter noted that the U.S. Department of Justice successfully 
prosecuted Barney Davis, a Spotted Saddle Horse trainer, and two of his 
employees for various violations of the HPA after a USDA investigation.
    The Act prohibits soring in all breeds of horses, which is why the 
U.S. Department of Justice was able to successfully prosecute a soring 
violation in a Spotted Saddle Horse. This particular case does not 
discount the proposed rule's statements on other breeds, nor does it 
invalidate our risk-based inspection method. We use the same inspection 
protocol on all breeds of horses covered under the Act. In our more 
than 50 years of enforcing the Act, soring has occurred far more 
frequently at Tennessee Walking Horse and racking horse shows than at 
Spotted Saddle horse shows,\32\ and the exclusion of Spotted Saddle 
Horses or any other breed from proposed Sec.  11.6(c) does not preclude 
a horse in those breeds at any covered event from being diagnosed as 
sore.
---------------------------------------------------------------------------

    \32\ See footnote 31.
---------------------------------------------------------------------------

    One commenter stated that the final rulemaking should reaffirm that 
the HPA applies to all horse show breeds as provided in proposed Sec.  
11.6(a) and (b), and that the new restrictions provided in Sec.  
11.6(c) specific to Tennessee Walking Horses, racking horses, and 
Spotted Saddle Horses are not intended to negate the continuing 
obligation of other breeds and shows to comply with the law.
    The new regulatory prohibitions on Tennessee Walking Horses and 
racking horses do not negate the obligation of other breeds also 
covered under the Act to be in compliance with the Act's provisions, 
which we monitor through a risk-based inspection protocol. The general 
prohibitions in Sec.  11.6(a) apply to all horse breeds. Further, while 
we do not include Spotted Saddle Horses under the prohibitions in Sec.  
11.6(c), this fact does not preclude APHIS from issuing a violation for 
a finding of soring, or a finding of use of a device is prohibited 
under Sec.  11.6(a), for a Spotted Saddle Horse or any other breed, or 
for a finding that the use of an action device, method, practice, or 
substance ``causes or can reasonably be expected to cause such horse to 
be sore or is otherwise used to mask previous and/or ongoing soring.'' 
These horses can be diagnosed as sore--or a device, method, practice, 
or substance can be determined to be prohibited under Sec.  11.6(a)--
regardless of breed.
    One commenter stated that USDA lacks evidence showing an absence of 
soring in other breeds and has itself acknowledged that other breeds do 
engage in soring. The commenter added that APHIS has found evidence of 
soring during inspections conducted at Spotted Saddle Horse and 
Missouri Fox Trotter events.
    As addressed above, APHIS focuses its risk-based enforcement 
efforts where soring is most concentrated, i.e., on Tennessee Walking 
Horse and racking horse shows, particularly Performance division events 
in which horses wear the tall pads and action devices and practice the 
``big lick.'' Persons exhibiting horses in events in which soring 
confers no competitive advantage have no incentive to sore their 
horses. Further, APHIS has never denied that soring occurs, albeit 
rarely, in breeds other than Tennessee Walking Horses

[[Page 39213]]

and racking horses.\33\ From FY 2017 to FY 2022, APHIS conducted 88 
inspections at 6 shows featuring Fox Trotter, Spotted Saddle Horses, 
Rocky Mountain Horses, and Mountain Horses and found a rate of 
noncompliance under 1 percent, compared to a 34 percent rate of 
noncompliance found by APHIS VMOs in inspections of Performance 
division Tennessee Walking Horses in FY 2022 alone.\34\

---------------------------------------------------------------------------

Action Devices, Pads, and Wedges (Sec.  11.6(c)(1) and (3))

    In the proposal, we invited public comment on the effects upon 
horses of action devices and pads, including wedges, whether used alone 
or in combination with other training methods. We have chosen to 
address comments on action devices and pads under one heading because 
many commenters made statements referring to them in combination.
    Numerous commenters expressed general support for prohibiting 
action devices and pads in order to prevent soring. A smaller number 
stated support for prohibiting action devices and pads because they 
unfairly allow sored horses to gain a competitive advantage. Several 
other commenters stated that action devices and pads, when used in the 
ways we have addressed above, are being used to sore horses.
    On the other hand, many commenters opposed prohibiting action 
devices and pads for Tennessee Walking Horses and racking horses, 
stating that pads, chains, and other action devices currently allowed 
under the regulations do not cause soring. A few commenters stated that 
the action devices, tall pads, and weighted shoes enhance the talent 
for the ``big lick'' that these horses already have. Another commenter 
stated that equine veterinarians that regularly treat the Tennessee 
Walking Horse credit the use of the pads with decreased laminitis but 
provided no support to back this claim.
    One commenter stated that prohibiting pads and action devices 
exceeds USDA's statutory authority because Congress made clear that the 
``twin goals'' of the Act are to prohibit soring while simultaneously 
protecting and enhancing fair competition. On this point, the commenter 
cited as support Thornton v. United Stated Department of 
Agriculture,\35\ quoting from it that ``[t]he Horse Protection Act was 
adopted to further two public purposes: the altruistic one of 
protecting the animals from an unnecessary and cruel practice and the 
economic one of eliminating unfair competition from sored pseudo-
champions that could fatally damage the Tennessee walking horse 
industry.'' \36\ The commenter posited that the proposed prohibition on 
pads and action devices among the Tennessee Walking Horse and racking 
horse industry would undermine fair competition by imposing collateral 
punishments on members of the industry who do not sore their horses, 
and thus was inconsistent with the Act.
---------------------------------------------------------------------------

    \35\ Thornton v. U.S. Dep't of Agric., 715 F.2d 1508 (11th Cir.) 
1983. This case provides that ``[t]he Horse Protection Act was 
adopted to further two public purposes: the altruistic one of 
protecting the animals from an unnecessary and cruel practice and 
the economic one of eliminating unfair competition from sored 
pseudo-champions that could fatally damage the Tennessee walking 
horse industry.'' Id. at 1511 (internal citations removed).
    \36\ Tennessee Walking Horse Celebration comment, page 27.
---------------------------------------------------------------------------

    The purpose of the Act is to prevent soring of horses, which has 
benefits for the welfare of horses and for eliminating unfair 
competition. The ``Congressional statement of findings'' states that 
horses shown or exhibited which are sore, where such soreness improves 
the performance of such horse, compete unfairly with horses which are 
not sore. Nothing in the regulations--which apply to all Tennessee 
Walking horses and racking horses, and which are aimed at addressing a 
practice, soring, that Congress found to cause unfair competition--
undermines fair competition.
    A commenter stated that it appeared that our rationale for 
proposing to ban pads and action devices on Tennessee Walking Horses 
and racking horses at regulated events was that, because some 
percentage of the owners and/or trainers who show horses in the 
Performance division of competition seem to be involved in soring, the 
way to address soring was to prohibit action devices and pads for all 
Tennessee Walking Horses and racking horses. The commenter stated that 
APHIS had misconstrued its authority under the Act to prohibit devices 
which, the commenter asserted, was limited to prohibiting only devices 
that cause soring. The commenter stated APHIS' proposed prohibitions 
were based on the erroneous legal premise that the Secretary has 
authority to eliminate any practice, however safe in itself, that seems 
to be associated in some loose statistical way with the members in the 
industry who engage in other practices that are already separately 
prohibited. The commenter stated that this interpretation of the Act 
could be used by APHIS to prohibit events entirely, because staging any 
horse show could contribute to soring.
    The commenter is incorrect that the Act limits prohibitions of 
devices to those that cause soring; section 5 (15 U.S.C. 1824(7)) and 
section 9 (15 U.S.C. 1828) jointly authorize APHIS to prohibit the use 
of devices by regulation if the prohibition is necessary to prevent 
soring. To that end, we disagree with the commenter's contention that 
there is no more than a loose statistical connection between the use of 
pads and action devices within the Tennessee Walking Horses and racking 
horse industry and incidences of soring; table 1 of the proposed rule 
indicated that noncompliance, primarily due to soring, is 1300 percent 
more likely in the Tennessee Walking Horse and racking horse division 
that uses pads and action devices than in the Tennessee Walking Horse 
and racking horse division that does not.\37\ The commenter's 
contention that APHIS' interpretation of the Act would authorize the 
wholesale prohibition of all horse shows is likewise in error. There is 
no provision of the Act that authorizes the elimination of horse shows 
and exhibitions.
---------------------------------------------------------------------------

    \37\ See proposed rule (88 FR 56930), table 1, FY 2017 to FY 
2022 average noncompliance rate detected by APHIS. Over the 6 years 
of data provided, noncompliance rates for Performance division 
Tennessee Walking Horses and racking horses averaged 25.1 percent, 
whereas noncompliance rates for flat-shod Tennessee Walking Horses 
and racking horses during that same period was 1.91 percent.
---------------------------------------------------------------------------

    The commenter also stated that because the Act does not prohibit 
practices or items that do not cause soring, it does not provide the 
USDA authority to prohibit action devices and pads. To the point 
regarding authority, we disagree that USDA lacks authority under the 
Act to prohibit pads and action devices. Section 5 (15 U.S.C. 1824) of 
the Act specifically prohibits, as unlawful, the showing or exhibiting 
of a sore horse. Section 2 (15 U.S.C. 1821) of the Act defines ``sore'' 
to include ``any other substance or device'' that ``has been used by a 
person on any limb of a horse . . . and, as a result of such . . . use 
. . . such horse suffers, or can reasonably be expected to suffer, 
physical pain . . . when walking, trotting, or otherwise moving . . . 
except that such term does not include'' use for therapeutic treatment. 
Section 9 (15 U.S.C. 1828) of the Act provides USDA with broad 
authority to issue regulations as deemed necessary to carry out the 
provisions of this chapter. Finally, section 5 (15 U.S.C. 1824(7)) of 
the Act authorizes APHIS to prohibit the showing or exhibiting of a 
horse which

[[Page 39214]]

is wearing or bearing any equipment, device, paraphernalia, or 
substance which the Secretary by regulation under section 9 (15 U.S.C. 
1828) prohibits to prevent the soring of horses. The proposed ban on 
action devices and pads for Tennessee Walking Horses and racking horses 
is therefore within the Agency's statutory authority in several ways. 
First, as we stated in the proposed rule and reiterate in this rule, 
action devices and pads may, under certain circumstances, and 
particularly in conjunction with other substances and practices, cause 
soring. It is thus within our statutory authority under section 2 (15 
U.S.C.1821) to prohibit their use insofar as they can cause soring. 
Second, irrespective of action devices and pads causing soring, there 
is a statistically elevated incidence of soring in the Performance 
division of the Tennessee Walking Horse and racking horse industry that 
is not found in other breeds that compete in pads and action devices, 
nor is it found in the flat-shod division of the Tennessee Walking 
Horse and racking horse industry, which does not compete in pads and 
action devices. The statistically elevated incidence of soring is thus 
breed and class-specific. It is also long-standing; again, by 1979, 
APHIS was already aware of increased incidence of soring within the 
Performance division. Finally, it has not been able to be addressed by 
other means, despite many efforts by the Agency to do so. Accordingly, 
the prohibitions in this rule are also within our statutory authority 
under sections 5 and 9 (15 U.S.C. 1824 and 1828) of the HPA as 
necessary to prevent the soring of horses.
    The same commenter added that the proposed ban on action devices 
and pads is arbitrary and capricious because the use of action devices 
and pads does not, per se, cause soring. Similarly, other commenters 
stated that pads and action devices have never been shown to cause 
soring.
    As we note above, we did not state in the proposed rule that pads 
and action devices per se cause soring; indeed, we pointed to specific 
examples where they are used for purposes that do not result in soring. 
What we said, however, is that they can cause soring. In this regard, 
we disagree with the latter commenters that pads and action devices do 
not cause soring. We have provided support in the proposal and this 
final rule indicating that chains and other action devices can inflict 
pain and exacerbate soring through repeated strikes to the leg in 
training and while the horse performs, particularly if the leg is 
already irritated from soring off-site (e.g., if irritating substances 
have also been applied to the skin or if the leg is sore from the use 
of heavier action devices at the horse's home barn, away from the 
show). Indeed, the NAS study notes that horses are often trained with 
action devices weighing in excess of the 6[hyphen]ounce action devices 
currently allowed for competition; action devices above this weight are 
prohibited during shows and exhibitions because they can cause 
soring.\38\ We have also provided that pads, when used in certain ways, 
can cause a horse's foot to strike the ground at an unnatural angle and 
induce tendon problems and soring over time, as can the repeated 
lifting of heavy pads and horseshoes.
---------------------------------------------------------------------------

    \38\ NAS study, page 81.
---------------------------------------------------------------------------

    The same commenter added that if action devices and pads were a 
cause of soring then the inspection results would have shown a 
violation rate of near 100 percent.
    As noted previously, the commenter's stated assumption was that the 
Act requires APHIS to establish that a device causes soring in order to 
prohibit its use during regulated events. The Act, however, does not 
require us to prove that a device always and per se causes soring in 
order to prohibit it. Rather, under section 5 (15 U.S.C. 1824(7)) and 
section 9 (15 U.S.C. 1828) of the Act, we may prohibit the use of a 
device through the issuance of regulations if we determine that the 
prohibition is necessary to prevent the soring of horses. Pads and 
action devices may be employed in certain ways to cause soring, and the 
class of Tennessee Walking Horses and racking horses that use pads and 
action devices, the Performance division, is disproportionately likely 
to have horses found to be sore following inspection. For these 
reasons, we consider it necessary to prohibit the use of pads and 
action devices on Tennessee Walking Horses and racking horses in order 
to prevent the soring of horses.
    As support for pads and action devices not causing soring, one 
commenter cited a joint statement by two major veterinary organizations 
and a pair of studies that evaluated the effects of pads and action 
devices on horses.\39\ In the joint statement by the American 
Veterinary Medical Association and the American Association of Equine 
Practitioners,\40\ the commenter quoted the statement that ``there is 
little scientific evidence to indicate that the use of action devices 
below a certain weight are detrimental to the health and welfare of the 
horse. . . .''
---------------------------------------------------------------------------

    \39\ National Celebration comment, page 22.
    \40\ Joint Statement of the Am. Med. Veterinary Assoc. and Am. 
Assoc. of Equine Practitioners, 2016 [included in Celebration 
comment, incorrectly dated 2012], Exhibit 17 of comment at <a href="https://www.regulations.gov/comment/APHIS-2022-0004-8788">https://www.regulations.gov/comment/APHIS-2022-0004-8788</a>.
---------------------------------------------------------------------------

    What the commenter declined to add was that the joint statement 
also ``support[s] a ban on the use of action devices and performance 
packages in the training and showing of Tennessee Walking Horses.'' The 
excerpt quoted by the commenter, in its full context, reads as follows:

    ``Action devices used in the training and showing of Tennessee 
Walking Horses include chains, ankle rings, collars, rollers, and 
bracelets of wood or aluminum beads. When used in conjunction with 
chemical irritants on the pastern of the horse's foot, the motion of 
the action device creates a painful response, resulting in a more 
exaggerated gait. While there is little scientific evidence to 
indicate that the use of action devices below a certain weight are 
detrimental to the health and welfare of the horse, banning action 
devices from use in the training and showing of Tennessee Walking 
Horses reduces the motivation to apply a chemical irritant to the 
pastern.''

    We agree with the professional judgment of the American Medical 
Veterinary Association and the American Association of Equine 
Practitioners, although we note the Act only covers showing, and not 
training, activities. If no action devices are allowed on Tennessee 
Walking Horses and racking horses during shows and exhibitions, there 
is less incentive to sore a horse as there will be no mechanism to 
strike the limb to induce the exaggerated show gait through pain.
    Further, the joint statement notes that ``[p]erformance packages 
(also called stacks or pads) . . . add weight to the horse's foot, 
causing it to strike with more force and at an abnormal angle to the 
ground. They also facilitate the concealment of items that apply 
pressure to the sole of the horse's hoof. Pressure from these hidden 
items produces pain in the hoof so that the horse lifts its feet faster 
and higher in an exaggerated gait.''
    The knowledge and expertise that these two veterinary organizations 
have regarding the horse industry and equine veterinary science is not 
in question. We concur with the full statement but have more to say 
below about the point regarding action devices below a certain weight 
being detrimental.
    The commenter also cited two other studies \41\ in claiming that 
the use of

[[Page 39215]]

action devices and pads does not cause a horse to be sore. We cited one 
of these studies (the ``Auburn study'') in the proposal to support the 
prohibition of action devices and pads as being necessary to prevent 
soring.

Horses in Response to Various Chemical and Physical Factors: Summary 
of the Research from September 1978 to December 1982, prepared by

Auburn University, and Soring in Tennessee Walking Horses: Detection

then of APHIS's Veterinary Lab Services, Ames, Iowa.
---------------------------------------------------------------------------

    The Auburn study involved exercising horses for 2 to 3 weeks 
wearing 2-, 4-, and 6-ounce chains (action devices), after which it was 
determined that the use of such chains for a duration of 2 to 3 weeks 
``did not produce any harmful effects to the horses' legs, with 
exception to some loss of hair from 6-ounce chains in the pastern 
areas.'' \42\ The commenter also reported that a USDA study in 1975 
similarly found no lesions present on horses wearing chains under 8 
ounces in weight.
---------------------------------------------------------------------------

    \42\ Auburn Study, Phase XI. Use of 2-, 4- and 6-Ounce Chains.
---------------------------------------------------------------------------

    While we acknowledge that the lighter chains in and of themselves 
appear in these particular studies to have no harmful effects on 
horses, we note that the Auburn study also applied irritating 
substances to horses' limbs and exercised them in such chains. Under 
these conditions, Dr. Ram C. Purohit, the study's author, reported that 
``[t]he combined use of detergent, chains, and mustard oil on the 
pasterns of horses causes lesions and tissue damage visible to the 
naked eye. They also cause alterations of the horse's behavior that are 
predictable.'' \43\
---------------------------------------------------------------------------

    \43\ Ibid., Phase VII, Simultaneous Use of Chemicals and Chains 
for Soring Horses.
---------------------------------------------------------------------------

    While the commenter noted that Dr. Purohit achieved these effects 
by exercising horses in 10-ounce chains, they did not address our point 
that ``if a horse may be trained sore using 10-ounce chains (or other 
weight and/or substance combinations) \44\ and then shown in 6-ounce 
chains, the use of the 6-ounce chain may reasonably be expected to 
cause the horse to experience pain while walking, trotting, or 
otherwise moving.'' \45\ Moreover, another quote from Dr. Purohit 
offered by the commenter, in which the doctor stated that his data 
``provided no evidence that chains of eight ounces or less used from 
three to five weeks in a normal, non-scarred horse produced 
inflammation or soreness,'' addresses neither the use of chains with 
irritating substances during training nor the effects of wearing chains 
of heavier weights for periods appreciably longer than 3 to 5 weeks.
---------------------------------------------------------------------------

    \44\ The NAS study indicated that ``[w]alking horses are often 
trained with action devices weighing in excess of the 6[hyphen]ounce 
action devices currently allowed for competition. The use of heavier 
or more cumbersome devices in training may be more likely to 
contribute to the formation of the lesions described in this 
report'' (page 81).
    \45\ 88 FR 56938.
---------------------------------------------------------------------------

    We mention this in order to highlight that the manner in which a 
horse is trained has a material bearing on whether the use of chains 
during shows and exhibitions contributes to soring, and precludes us 
from saying that chains of a certain weight cannot be associated with 
soring. For example, if an irritant is applied to a horse's limbs 
during training and/or the horse has been trained in heavy chains, 
performing in chains of 6 ounces or less may cause the horse to suffer 
physical pain or distress when moving during the competition, and thus 
to meet the statutory definition of being ``sore.'' This is entirely 
consistent with the findings of the Auburn study and highlights one of 
the limitations of the HPA: APHIS has no authority over training 
practices under the HPA; our authority is limited to the horse shows, 
exhibitions, sales, and auctions covered by the Act. We are limited to 
determining, primarily through inspection, whether horses at such 
events are sore. Within these constraints, it is the Agency's finding 
that Tennessee Walking Horses and racking horses in the Performance 
division are disproportionately likely to be determined to be sore, 
regardless of the weight of the chains in which they perform.
    The commenter also stated that this rulemaking reverses APHIS' 
position on the use of 6-ounce chains, stating that ``not only was the 
evidence USDA relies on today in front of it at the time it adopted the 
current regulations permitting the use of pads and action devices in 
1989, but it relied on that evidence [i.e., the Auburn study] to reach 
a conclusion--action devices weighing 6 ounces or less are permissible 
because they do not cause soring--that is completely at odds with the 
ban the Agency now proposes.'' \46\ The commenter also cited a July 28, 
1988 interim rule (53 FR 28366-28373), in which USDA stated that 
``while chains and other action devices weighing more than 6 ounces can 
sore horses, those weighing 6 ounces or less are not themselves likely 
to cause soring'' (page 28370). The commenter concluded that ``USDA may 
not change course and ban action devices by relying on a study that 
undermines the rationale for a complete ban on action devices and 
pads.'' \47\
---------------------------------------------------------------------------

    \46\ National Celebration comment, page 23.
    \47\ Ibid., page 24.
---------------------------------------------------------------------------

    The commenter is incorrect that the Agency changed course without 
providing any indication in the proposed rule that its thinking had 
evolved regarding the meaning and import of the Auburn study since 
1988. The 1988 interim rule assumed that horses would be trained and 
shown in chains of equivalent weight, and cited the Auburn study to 
establish a de minimis chain weight in compliance with a Court 
Order.\48\ The 1988 interim rule cited no data in support of this 
assumption regarding training, and this assumption, if ever true, no 
longer corresponds to industry practices. To that end, we cited the NAS 
study to indicate that use of heavy chains and devices during training 
was currently widespread within the Tennessee Walking Horse and racking 
horse industry. Given what we now know about training practices, other 
aspects of the Auburn study that we assumed to be inoperative in 1988 
are in fact germane.

(D.D.C. 1988).
---------------------------------------------------------------------------

    We proposed under paragraph (c)(3) to prohibit all pads and wedges 
on any Tennessee Walking Horse or racking horse at any show or other 
covered event, unless the horse has been prescribed and is receiving 
therapeutic treatment involving the use of pads or wedges as approved 
in writing by a licensed veterinarian.
    A commenter stated that APHIS had acknowledged that pads and action 
devices do not cause soring by choosing not to ban their use in other 
breeds. The commenter added that the pads used by Tennessee Walking 
Horses during training and those used by other breeds were the same, 
and cited the USEF rulebook as evidence that Arabian, Anglo-Arabian, 
Andalusian, Friesian, Saddlebred, and Morgan horses may all be shown in 
pads. The commenter also disagreed with our contention that the gait of 
Tennessee Walking Horses in the Performance division is noticeably 
different from that of other Performance breeds, and submitted photos 
that, the commenter contested, showed a similar accentuated gait in 
Friesian, Hackney, American Saddlebred, and other horse breeds.
    Again, the commenter's stated assumption is that APHIS has 
statutory authority to prohibit a device, such as pads, only if it 
causes soring. As we have stated above, section 5 (15 U.S.C. 1824(7)) 
and section 9 (15 U.S.C. 1828) of the Act authorize APHIS to prohibit 
the use of a device by issuing regulations if the prohibition is 
necessary to prevent soring.

[[Page 39216]]

    Depending on how they are used or designed, pads can cause soring. 
However, we are not banning them for Tennessee Walking Horses and 
racking horses because they always and per se cause soring, which they 
do not. Were we to do so, the commenter would be correct in assuming 
the prohibition should be extended to all other padded breeds. Rather, 
we are prohibiting the use of pads in Tennessee Walking Horses and 
racking horses because the Performance division, in which horses of 
these breeds routinely exhibit in pads, has a disproportionately high 
incidence of soring relative to other breeds and even to flat-shod 
Tennessee Walking Horses and racking horses. As we have stated 
previously, the incidence of soring is disproportionately more likely 
in Tennessee Walking Horses and racking horses that compete in pads 
than other breeds, and noncompliance, particularly in the form of 
soring, is even 1,300 percent more likely than other flat-shod classes 
of Tennessee Walking Horses and racking horses. This disproportionate 
incidence makes it necessary to prohibit the use of pads for Tennessee 
Walking Horses and racking horses at regulated events in order to 
prevent soring.
    A commenter also claimed that our proposed prohibition of pads is 
lacking on the same grounds as action devices, claiming that pads also 
do not cause soring.
    As noted above, we are prohibiting the use of pads in Tennessee 
Walking Horses and racking horses because the only Tennessee Walking 
Horse and racking horse class that routinely exhibits in pads has a 
disproportionately high incidence of soring, relative to other breeds 
and even to flat-shod Tennessee Walking Horses and racking horses. 
Further, we noted above that the uniquely tall stacks of pads and 
wedges worn in exhibition by Performance division Tennessee Walking 
Horses and racking horses, when employed in certain ways, can cause a 
horse to become sore, a point with which the American Veterinary 
Medical Association and American Association of Equine Practitioners 
concur.
    The commenter further reasoned that ``if raising a horse's heel 
through pads could cause soring by itself, then USDA would necessarily 
need to ban the use of pads in all HPA Breeds.'' \49\
---------------------------------------------------------------------------

    \49\ National Celebration comment, page 24.
---------------------------------------------------------------------------

    Again, we never contended that pads always and per se cause soring; 
indeed, we specifically pointed to instances in other breeds where 
horses are able to use pads (and action devices) without either item 
causing soring, and where instances of soring in those breeds are rare. 
However, we did indicate that pads can cause soring, either on their 
own or in conjunction with other substances and practices. 
Additionally, there is a statistically elevated incidence of soring 
among horses in the Performance division of the Tennessee Walking Horse 
and racking horse industry in comparison to other breeds that use pads 
during competition.
    The commenter further contended that ``of course the pads used by 
these other breeds during training are no different from those used by 
Tennessee Walking Horses.'' This contention is in error and does not 
acknowledge the obvious difference between the tall stacks of pads and 
wedges used to train and show Performance division Tennessee Walking 
Horses and the much thinner protective pads used by most other breeds.
    The same commenter cited an affidavit by USDA's former Chief Staff 
Veterinarian for Horse Protection matters from 1973 to 1978, Dr. Lois 
Hinson, who testified that clinics that USDA conducted definitively 
prove that pads per se do not cause inflammation or soring in the 
hooves of horses, but rather extreme angulation of the hoof causes 
inflammation and soring. The commenter indicated that these studies are 
the only ones the commenter is aware of that evaluated whether pads 
cause soring on Tennessee Walking Horses and racking horses.
    As we noted previously, one of the commenter's stated assumptions 
was that APHIS could only ban pads if the pads always and per se cause 
soring. As previously articulated, we are prohibiting pads on Tennessee 
Walking Horses and racking horses not because they always and per se 
cause soring, but because they can cause soring. Soring is so 
disproportionately likely in Tennessee Walking Horses and racking 
horses wearing pads that the prohibition is necessary in order to 
prevent soring. This is consistent with our authority under section 5 
(15 U.S.C. 1824(7)) and section 9 (15 U.S.C. 1828) of the Act. 
Accordingly, the studies and affidavit of Dr. Hinson are not relevant 
to our proposed prohibition.
    The commenter also stated that USDA lacks evidence showing an 
absence of soring in other breeds and has itself acknowledged that 
other breeds do engage in soring.
    We note that USDA has never stated that other breeds do not sore 
their horses. What we have stated in the proposal and in this final 
rule is that breeds other than Tennessee Walking Horses and racking 
horses have not been found to sore horses with any frequency, as soring 
confers no competitive advantage to horses that do not perform the 
exaggerated ``big lick'' step in Performance division shows.
    Further, the same commenter stated that USDA has not provided 
evidence that violations such as pressure shoeing are otherwise 
impossible to detect beneath pads, or that such violations occur with 
such frequency that a ban on pads is warranted. The commenter added 
that pressure shoeing can be detected currently through radiography and 
other means.
    The Auburn study found that the ability to detect pressure soring 
(the illegal application and/or use of bolts, screws, blocks, hoof 
packing material, and other methods of pressure) through visual and 
physical inspection of the soles of horses' hooves is limited because 
pads obscure the solar surface of the foot.\50\ APHIS agrees with this 
finding. Moreover, because evidence of pressure soring can be removed 
prior to inspection, the evidence of soring would not necessarily 
appear on radiographs as the commenter contends.

---------------------------------------------------------------------------

    One commenter recommended that we include in Sec.  11.6(c) a 
clarification that explicitly allows applications of nails to limbs 
(feet) to secure horseshoes.
    We acknowledge the commenter's point but do not find it necessary 
to add such a clarification, as nails are usually necessary to secure 
the shoe to the hoof.
    Two commenters opposed to the prohibition on action devices and 
pads cited a 2017 study \51\ that found no evidence of change in 
biological markers associated with stress and pain with stacked pads 
and action devices.

    APHIS is aware of the study cited by the commenters as well as the 
limitations of the study that the authors themselves pointed out, 
including that the horses were never exercised at a running walk, there 
were no riders on the horses when exercised, and the evaluation period 
of when the horses were outfitted with stacked wedge pads and chains 
was only 5 days. Accordingly, the authors of the study themselves 
acknowledged that ``these findings should not be extrapolated to the 
long-term use of such devices.'' \52\ While the chains used on the 
horses in

[[Page 39217]]

this study were 6-ounce chains, Tennessee Walking Horses can be trained 
with chains much heavier than what the regulations allow,\53\ along 
with the use of prohibited substances on the pasterns of these horses 
in training to make them more reactive to action devices during shows.

    \53\ Equine experts on the NAS Committee also raise this point 
in their study (page 81).
---------------------------------------------------------------------------

    Several commenters stated that banning pads and action devices on 
Tennessee Walking Horses and racking horses constitutes a violation of 
their rights under the U.S. Constitution. Specifically, one commenter 
stated that the Takings Clause of the Fifth Amendment of the U.S. 
Constitution provides that when the Federal Government takes private 
property for a public use, it must provide just compensation. The 
commenter expressed concern that if USDA proceeds with the ban on pads 
and action devices, its actions will amount to a taking because it 
would destroy all the value in Tennessee Walking Horses trained to 
compete in the performance division by essentially banning the sport in 
which they compete.
    To support this point, the commenter provided statements from 
several trainers \54\ supporting why the value of such horses would 
diminish. Some trainers cited the time and cost required to retrain a 
horse to compete flat-shod (without pads), while others stated, without 
explanation, that very few horses trained to compete in the Performance 
division are able to make the transition to competing flat-shod. 
Underscoring this latter point, the commenter added that ``[I]t would 
be like asking a professional athlete to drop one sport and train for 
another.'' Similarly, another commenter opined that Performance 
division Tennessee Walking Horses have been specifically bred and 
trained to compete with action devices and pads and cannot simply be 
retrained to compete as a flat-shod horse.
---------------------------------------------------------------------------

    \54\ National Celebration comment, page 32.
---------------------------------------------------------------------------

    We disagree with the commenter that the regulations would result in 
the loss of all economically valuable use of Tennessee Walking Horses 
competing in the Performance division. The statements from trainers 
provided by the commenter that cite the time and cost required to 
retrain such a horse actually underscore that retraining is possible. 
If the regulations deprived the horse of all economic value regardless 
of its use, retraining would be either impossible or materially 
irrelevant. Indeed, based on the statements provided, there is no basis 
to conclude that the value of Tennessee Walking Horses competing in the 
Performance division--that is, trained to perform in stacked pads and 
action devices--would necessarily be reduced if they cannot compete 
wearing these items. It is, of course, possible that this could occur 
and that the prohibitions in the rule will render some horses less 
valuable. However, to the extent that this foregone value was derived 
from an illicit and illegal activity, soring, that was being pursued in 
order to gain a competitive advantage, this reduction in value is 
foreseen by the Act and consistent with it. And again, a reduction in 
value, particularly illicitly derived value, is not tantamount to loss 
of all economically valuable use; even if there were some basis to 
conclude that the regulations would result in some limited reduction in 
value, that is not sufficient to show the loss of all economically 
valuable use.
    First, while the commenter implies that horses competing flat-shod 
and in stacked pads are engaging in two dramatically different 
activities, a prominent Tennessee Walking Horse industry organization 
\55\ notes that they both actually employ the same basic gaits--the 
flat-foot walk, the running walk, and the canter. These are described 
by the organization as ``natural, inherited gaits,'' \56\ with the only 
difference between flat-shod and Performance gaits being that the 
latter is practiced with ``more animation and accentuated brilliance.'' 
\57\ We cite this organization's statement to show that the industry 
itself notes that the same gaits, described as being natural and 
inherent to the breed, are used by horses competing with and without 
stacked pads and actions devices, the main difference between the two 
being the degree of animation.

    Second, despite the claim that such horses cannot be retrained to 
show without pads, commenters did not explain specifically why such 
horses cannot practice an inherited gait on their natural hooves, 
rather than on unnaturally tall pads. Further, trainers and other 
commenters responding to this rulemaking have stated that flat-shod 
horses can achieve the animated ``big lick'' step with proper training. 
If the only elements missing from a show are pads and action devices, 
we question why their absence alone will affect the value of a horse in 
terms of its ability to show. Nowhere do commenters explain how these 
items work in any benign way to animate what they otherwise claim to be 
the natural and inherited ability of such horses to practice the ``big 
lick'' step.
    One commenter opined that Performance division Tennessee Walking 
Horses have been specifically bred and trained to compete with action 
devices and pads and cannot simply be retrained to compete as a flat-
shod horse, although this and other commenters provided no specific 
evidence that Performance division horses trained to perform with the 
use of pads and action devices cannot perform well without them. We 
note that other breeds of horses can transition successfully from one 
sport to another. Racehorses are successfully retrained to practice 
dressage and jumping, and other breeds have switched easily from 
English- to Western-style riding, and the industry itself indicates 
that the horses can easily be retrained to different purposes.\58\ 
While commenter concern over how this rulemaking may affect a horse's 
value is understandable, we note that this rulemaking makes no changes 
to the ability of horses to freely compete in shows and exhibitions. 
Further, the evidence that the commenter provided, as well as evidence 
we obtained from some commenters and the industry website discussed 
above, suggests they can be retrained.
---------------------------------------------------------------------------

    \58\ Ibid.
---------------------------------------------------------------------------

    Numerous commenters opined that the prohibition on action devices 
and pads would diminish public interest in shows and result in the 
cultural and economic decline of the Tennessee Walking Horse industry. 
Some stated that Performance division horses that use pads and action 
devices are essential to horse shows and, without such classes, owners 
and spectators would lose interest in the shows.
    The commenters ignore the fact that flat-shod classes compete 
widely within the Tennessee Walking Horse industry and are of growing 
popularity. This fact suggests that the use of pads and action devices 
are not essential to the survival of shows featuring such breeds. 
Without pads and action devices, the same shows could be held under the 
same management, and, if trained to go flat-shod, which, again, we have 
reason to believe is possible, the same horses could continue to 
compete in them with the same custodians and trainers. To that end, we 
again note that the industry itself indicates that Tennessee Walking 
Horses can be easily retrained to different purposes, and that the 
basic gait for padded and flat-shod Tennessee

Walking Horses is the same. This comports with evidence provided by 
veterinary organizations with expertise in equine medicine and humane 
animal care, which we discuss immediately below, and which suggests 
that Tennessee Walking Horses can be retrained to go flat-shod in far 
less time than we proposed to afford for the transition.
    Interest in flat-shod shows is growing nationwide. In a 2015 
article,\59\ the president of a prominent Tennessee Walking Horse 
owners' association noted that entries for its sanctioned, flat-shod 
shows across the country almost doubled from 2012 to 2014, adding that 
the number of such shows has also increased. The economic analysis 
accompanying this final rule provides an evaluation of its economic 
impact on the affected segments of the horse industry.

    Some commenters stated that USDA has failed to conduct a proper 
cost-benefit analysis for the proposed ban on action devices and pads.
    We address the topic of economic impacts in the economic analysis 
prepared for this final rule.
    We proposed to have the prohibition on pads and wedges, and 
artificial toe extensions, on Tennessee Walking Horses and racking 
horses to become effective 270 days after promulgation of a final rule. 
In the proposal, we also invited comments on whether this is an 
appropriate timeframe for transitioning to a prohibition on pads and 
wedges, and artificial toe extensions.
    Many commenters stated that the USDA should reevaluate its proposal 
to delay the ban on hoof pads for Tennessee Walking Horses and racking 
horses for 270 days after finalizing the regulations. They noted that 
the proposed rule states that pads can induce pain by ``caus[ing] a 
horse's foot to strike the ground at an unnatural angle.'' One 
commenter added that Tennessee Walking Horses ``sometimes have their 
pads/wedges removed at the conclusion of show season with no negative 
ramifications to the horse. The transition from pads to flat-shod can 
be and sometimes is accomplished in a day, as long as the hoof is 
trimmed to maintain the same proportions.'' One commenter stated that 
no scientific evidence was provided to support the claim that 
transitioning the horse from padded to flat-shod requires a set period 
of time. Some commenters additionally asked that artificial toe 
extensions not have the 270-day phaseout period. Another commenter 
asked if owners are allowed to exhibit with these devices and pads up 
and until the end of the 270-day period and deemed a 90-day period 
sufficient, adding that those affected and covered under this 
regulation have had sufficient time to plan and institute training 
without the use of these devices.
    In the proposed rule, we had stated that it takes approximately 6 
to 8 months for a padded horse to become acclimated to walking and 
performing without pads. However, we reviewed the evidence provided by 
veterinary organizations with expertise in equine medicine and humane 
animal care that stated a grace period was not necessary for 
acclimation to walking without pads. We reconsidered the 270-day 
requirement and the evidence on which we based it, as well as 
statements from several commenters that a 270-day phaseout period for 
pads and toe extensions could unduly extend the time that horses are 
suffering from soring as a result of continued use of these items. 
Accordingly, we are establishing February 1, 2025, as the date on which 
pads and toe extensions can no longer be used on Tennessee Walking 
Horses and racking horses. This change reduces the amount of time that 
horses are made to wear these items.
    A commenter stated that if therapeutic treatment using a pad or 
wedge is allowed, there is potential for pressure shoeing. The 
commenter recommended that ``pressure shoeing'' be defined clearly in 
Sec.  11.1 to prevent uncertainty or ambiguity.
    We agree with the commenter that a potential for pressure shoeing 
exists whenever pads and wedges are used, which is a reason we are 
prohibiting such items to prevent soring. However, the practice can be 
applied in many ways and to define the term ``pressure shoeing'' in one 
prescriptive way may limit APHIS' options for citing it as a violation. 
As we go forward with these regulatory changes, we will evaluate the 
potential for this practice in conjunction with the use of therapeutic 
pads and wedges.
    Some commenters stated that pads are sometimes used as a way to 
alleviate pain and prevent damage to hoof structures and related 
connective tissue in all breeds of horses.
    Pads with legitimate therapeutic applications may be used on 
Tennessee Walking Horses and racking horses in accordance with the 
veterinary prescription requirements in Sec.  11.14(b).
    A commenter suggested that we include limits on dimensions of 
therapeutic pads and wedges, adding that a veterinarian may be 
persuaded by owners and trainers to prescribe such items that are 
identical to those currently used in performance packages.
    We do not consider it necessary to include such specific dimensions 
within the regulations. As management is required to maintain all 
records of therapeutic treatment, including prescription information, 
APHIS can evaluate and determine the suitability of any such 
prescription for pads and wedges as warranted. If APHIS disputes a 
therapeutic treatment at a show on veterinary grounds, the horse will 
not be allowed to show.\60\ If APHIS disputes such a therapeutic 
treatment in the records required to be maintained, we reserve the 
right to contact the appropriate State veterinary board regarding the 
veterinarian prescribing that treatment.

therapeutic treatment can do so in accordance with 9 CFR 11.5.

    Several commenters opposed to the proposed rule stated that the 
existence of 15-year-old and older Tennessee Walking Horses and racking 
horses still showing in pads is evidence that soring is neither a 
common nor serious problem.
    We incorporate our earlier rationale for the prohibition and note 
that the presence of older horses wearing pads in shows is neither 
evidence that pads are harmless nor that horses performing a
