Action
Chronic Wasting Disease Detection and Response Rules
Recommended Adoption of Proposed Changes
August 24, 2023

I. Executive Summary: Staff seeks adoption of proposed changes to rules establishing Chronic Wasting Disease (CWD) Containment Zones, Surveillance Zones and requirements affecting deer breeding facilities where CWD has been discovered. The proposed amendments would:

Establish a Containment Zone (CZ) for portions of Hunt and Kaufman counties;
Establish a new CZ for portions of Bexar County;
Establish new Surveillance Zones (SZs) in Bexar, Sutton, Zavala, Frio, and Brooks counties;
Establish additional surveillance requirements for deer breeding facilities where CWD is detected, to include euthanization (within seven days) of deer in which CWD is detected via ante-mortem testing; daily mortality inspections; the immediate reporting of such mortalities; and the testing of mortalities within one business day; and
Correct existing typographical errors in zone delineations from a previous rulemaking.

II. Discussion: Texas Parks and Wildlife Department (TPWD) began establishing CWD CZs, SZs, and Buffer Zones in 2012 following the detection of CWD in the Hueco Mountains. The purpose of those CWD Zones was to determine the geographic extent and prevalence of the disease while containing it by limiting the unnatural movement of live CWD-susceptible species as well as the movement of carcass parts. TPWD has continually reassessed, adapted, and enhanced its CWD surveillance strategy for captive and free-ranging deer populations in Texas. Following detection of CWD in breeding facilities in 2015, TPWD increased its post-mortem surveillance testing requirements from 20 percent to 80 percent of eligible mortalities for deer breeding facilities. Additionally, Texas became the first state to implement ante-mortem surveillance strategies. In 2021, after seven additional breeding facilities were found to be CWD positive, TPWD, with the input of the Texas Animal Health Commission (TAHC), again increased its surveillance requirements by requiring 100 percent of eligible mortalities to be tested and the submission of a “not detected” ante-mortem test for each breeder deer as a condition of release. These changes improved regulatory consistency between TPWD, TAHC, and the United States Department of Agriculture and established a framework for responding to epidemiologically linked facilities. The rules have not only greatly enhanced TPWD’s ability to identify and respond to CWD positive breeding facilities, but they have also increased confidence in the quality of reported surveillance data.

Following additional recent detection of CWD on release sites associated with a positive deer breeding facility in Hunt County, TPWD has proposed rules to implement a new CZ in Hunt and Kaufman counties. Additionally, recent CWD detections necessitate the creation of a new CZ in Bexar County, along with SZs in Bexar, Sutton, Zavala, Frio, and Brooks counties.

While there have been notable improvements in the surveillance requirements for deer breeding facilities, staff have also identified deficiencies in the rules as they relate to CWD positive herds. Current rules address TPWD’s CWD response in relation to epidemiologically linked herds, but they do not specifically outline requirements for the CWD positive herds themselves. To expedite TPWD’s response to the infected herds and mitigate the risk of CWD transmission to other nearby deer populations, staff proposes additional requirements, to include the post-mortem testing of all deer confirmed to be positive for CWD through antemortem testing (by euthanasia within seven days of confirmation), daily mortality inspections, immediate reporting of mortalities, and testing of mortalities within one business day.

At the Commission Work Session meeting on May 24, 2023, staff was authorized to publish the proposed rules in the Texas Register for public comment. The proposed rules appeared in the July 11, 2023, issue of the Texas Register (48 TexReg 3975). A summary of public comment on the proposed rules will be presented at the time of the meeting.

III. Recommendation: Staff recommends the Texas Parks and Wildlife Commission adopt the following motion:

“The Texas Parks and Wildlife Commission adopts amendments to 31 Texas Administrative Code §§65.81, 65.82, and 65.99, concerning Disease Detection and Response, as listed in Exhibit A, with changes as necessary to the proposed text as published in the DATE, issue of the Texas Register (48 TexReg 3975).”

DISEASE DETECTION AND RESPONSE RULES

PROPOSAL PREAMBLE

1. Introduction.

The Texas Parks and Wildlife Department proposes amendments to 31 TAC §§65.81, 65.82, and 65.99, concerning Disease Detection and Response.

The proposed amendments would function collectively to refine surveillance efforts as part of the agency’s effort to manage chronic wasting disease (CWD).

Chronic wasting disease (CWD) is a fatal neurodegenerative disorder that affects some cervid species, including white-tailed deer, mule deer, elk, red deer, sika, and their hybrids (referred to collectively as susceptible species). It is classified as a TSE (transmissible spongiform encephalopathy), a family of diseases that includes scrapie (found in sheep), bovine spongiform encephalopathy (BSE, found in cattle and commonly known as “Mad Cow Disease”), and variant Creutzfeldt-Jakob Disease (vCJD) in humans.

Much remains unknown about CWD, although robust efforts to increase knowledge are underway in many states and countries. The peculiarities of its transmission (how it is passed from animal to animal), infection rate (the frequency of occurrence through time or other comparative standard), incubation period (the time from exposure to clinical manifestation), and potential for transmission to other species are still being investigated. Currently, there is scientific evidence to suggest that CWD has zoonotic potential; however, no confirmed cases of CWD have been found in humans. Consequently, both the Centers for Disease Control and Prevention and the World Health Organization strongly recommend testing animals taken in areas where CWD exists, and if positive, recommend not consuming the meat. What is known is that CWD is invariably fatal to certain species of cervids and is transmitted both directly (through animal-to-animal contact) and indirectly (through environmental contamination). If CWD is not contained and controlled, the implications of the disease for Texas and its multi-billion-dollar ranching, hunting, wildlife management, and real estate economies could be significant.

The department has engaged in several rulemakings over the years to address the threat posed by CWD, including rules to designate a system of zones in areas where CWD has been confirmed or could reasonably be expected. The purpose of those CWD zones is to determine the geographic extent and prevalence of the disease while containing it by limiting the unnatural movement of live CWD-susceptible species as well as the movement of carcass parts.

The department’s response to the emergence of CWD in captive and free-ranging populations is guided by the department’s CWD Management Plan (Plan) https://tpwd.texas.gov/huntwild/wild/diseases/cwd/plan.phtml. Developed in 2012 in consultation with the Texas Animal Health Commission (TAHC), other governmental entities and conservation organizations, and various advisory groups consisting of landowners, hunters, deer managers, veterinarians, and epidemiologists, the Plan sets forth the department’s CWD management strategies and informs regulatory responses to the detection of the disease in captive and free-ranging cervid populations in the state of Texas. The Plan is intended to be dynamic; in fact, it must be so in order to accommodate the growing understanding of the etiology, pathology, and epidemiology of the disease and the potential management pathways that emerge as it becomes better understood through time. The Plan proceeds from the premise that disease surveillance and active management of CWD once it is detected are absolutely critical to containing it on the landscape. Accordingly, the first step in the department’s response to CWD detections is the timely establishment of management zones around locations where detection occurs. One type of management zone is the containment zone (CZ), defined by rule as “a department-defined geographic area in this state within which CWD has been detected or the department has determined, using the best available science and data, CWD detection is probable.” Within a CZ, the movement of live deer is subject to restrictions and the presentation of harvested deer at a department check station is required. In addition, deer carcass movement restrictions set forth in §65.88 of Subchapter B, Division 1 apply. In addition to CZs, current rules provide for surveillance zones (SZs), defined by rule as “a department-defined geographic area in this state within which the department has determined, using the best available science and data, that the presence of CWD could reasonably be expected.” Within a SZ, the movement of live deer is subject to restrictions and the presentation of harvested deer at a department check station is required. In addition, deer carcass movement restrictions set forth in §65.88 of Subchapter B, Division 1 apply.

The Texas Parks and Wildlife Commission recently directed staff to develop guidelines or a standard operating procedure (SOP) with respect to the establishment and duration of the various management zones. In cases where CWD is discovered in a deer breeding facility but not on associated release sites, the department will not establish a SZ if the following can be verified: 1) the disease was detected early (i.e., it has not been in the facility long); 2) the transmission mechanism and pathway are known; 3) the facility was promptly depopulated following detection; and 4) there is no evidence that free-ranging deer populations have been compromised. If any of these criteria is not satisfied, a SZ will be established to consist of all properties that are wholly or partially located within two miles of the property where the positive breeding facility is located. However, in situations where CWD is detected in a free-ranging deer that is epidemiologically linked with a CWD-positive breeding facility, the department has little choice but to formally impose a CZ in response. The SOP dictates that a CZ consist of all properties wholly or partially located within five miles of the property (or properties) where CWD was detected.

As noted previously in this preamble, the department has been engaged in a long-term effort to stem the spread of CWD; however, by 2021 it was apparent that more robust measures were warranted because CWD was still being detected in additional deer breeding facilities, as well as release sites associated with deer breeding facilities. The commission adopted those rules, which require higher rates of testing, ante-mortem (live-animal) testing of breeder deer prior to release, and enhanced recordkeeping and reporting measures, in December of 2021 (46 TexReg 8724). This year is the first full year of the applicability of those measures. The department notes that other rulemakings have enhanced provisions regarding carcass movement restrictions.

The proposed amendment to §65.81, concerning Containment Zones; Restrictions, would establish a new CZ 7 in Hunt and Kaufmann counties in response to recent detections of CWD in deer on release sites associated with a CWD-positive deer breeding facility. That facility is already within Surveillance Zone 7, which was created in response to the initial detection of CWD on that premise. On March 17, 2023, the department received confirmation that CWD was present on a release site associated with the CWD-positive deer breeding facility for which SZ 7 was created. Two additional positives have been detected on an associated release site in Kaufman County (a 4.5-year-old male and a 5.5 year-old male) that is epidemiologically linked to the CWD-positive breeding facility in Hunt County. The proposed amendment would also establish that the geographic areas described by the rule represent a five-mile radius surrounding each property where CWD has been detected, and that the zone includes all properties wholly or partially within those areas. The proposed amendment is intended to replace an emergency rule adopted on May 26, 2023 (June 16, 2003 issue of the Texas Register, 48 TexReg 3009), which took effect immediately.

In addition, the proposed amendment would establish a new CZ in Bexar County (CZ 8). On May 25, 2023, the department received confirmation that a free-ranging deer (a 6.5-year-old female) killed pursuant to a TTP (Trap, Transfer, and Process) permit in Bexar County had tested positive for CWD.

The proposed amendment to §65.82, concerning Surveillance Zones; Restrictions, would establish new Surveillance Zone (SZ) 18 in Bexar County, new SZ 19 in Sutton County, new SZ 20 in Zavala County, new SZ 21 in Frio County, and new SZ 22 in Brooks County, all in response to the continued detection of CWD in deer breeding facilities. On May 3, 2023, the department received confirmation that a 3.75-year-old buck deer in a deer breeding facility in Sutton County had tested positive for CWD. In accordance with the department’s CWD Management Plan and SOP, the department is establishing a SZ in a two-mile radius around the property where the Sutton County positive was detected. The proposed SZ in Bexar County is in response to the confirmation of CWD in Bexar County described earlier in this preamble in the discussion of the establishment of a CZ in Bexar County. On March 10, 2023, CWD was confirmed in three 2-year-old males within a deer breeding facility in Zavala County, and on April 5, 2023, CWD was confirmed in a 3-year-old male within a deer breeding facility in Frio County. On June 28, 2023, CWD was detected in a 2-year old female deer in Frio County and on July 7, 2023, CWD was detected in a 5-year-old female deer in a deer breeding facility in Brooks County. In keeping with the department’s CWD Management Plan and the SOP, a SZ with a two-mile radius around each of those locations would be established by the proposed amendment. The department notes that confirmation of CWD by the diagnostic lab is a two-test process, intended to eliminate the possibility of a false positive. At the time the proposed amendment was submitted for publication, the department had not received confirmation of the suspect test results for the deer breeding facilities in Frio and Brooks counties; therefore, if CWD is not confirmed in those breeding facilities, the proposed creation of SZ 21 and 22 would be withdrawn.

The proposed amendment also clarifies that the geographic areas described by the rule represent the two-mile radius around the property where CWD was detected, and that the zone includes all properties wholly or partially within those areas.

Finally, the proposed amendment would correct typographical errors in the published delineations for SZ 11, which was established in a previous rulemaking (48 TeReg 2048). As published, some of the coordinate pairs describing the SZ lacked the negative sign indicating that the locations being described are in the western hemisphere.

The proposed amendment to §65.99, concerning Breeding Facilities Epidemiologically Connected to Deer Infected with CWD, would add new subsection (j) to require the euthanization of breeder deer within seven days of notification of confirmation of a positive ante-mortem CWD test result, the submission of post-mortem tissue samples (accompanied by both ears and required ear tags) of such deer within one day of euthanization, and daily facility inspections (with any mortalities to be immediately reported to the department, and the collection and submission of post-mortem tissue samples from test-eligible mortalities within one business day of collection). The proposed amendment also would retitle the section to reflect its applicability to deer breeding facilities in which CWD has been detected. From an epidemiological perspective, it is important to definitively assess the progress of disease in an individual animal as quickly as possible in order to determine the temporal parameters of disease transmission in the population. Immediate euthanization and post-mortem testing of all animals that test positive via ante-mortem testing gives the department and the regulated community the best chance of ensuring that disease transmission is mitigated as soon as possible in a breeding facility. Similarly, the proposed requirement for daily inspections and immediate reporting and testing of mortalities is necessary to gain additional understanding of disease status within the facility. The proposed rule also would require the submission of both ears and the required identification tags in order for the department to definitively establish the unique identity of the deer in question for future epidemiological investigation. Under current rule, a facility that returns a positive test result is automatically designated “not movement qualified” (NMQ) and is prohibited from transferring deer in or out of the facility; therefore, the proposed amendment would repeat that requirement simply for clarity and emphasis.

2. Fiscal Note.

Robert Macdonald, Regulations Coordinator, has determined that for each of the first five years that the rules as proposed are in effect, there will be no fiscal implications to state and local governments as a result of enforcing or administering the rules as proposed, as department personnel currently allocated to the administration and enforcement of disease management activities will administer and enforce the rules as part of their current job duties and resources.

3. Public Benefit/Cost Note.

Mr. Macdonald also has determined that for each of the first five years the amendments as proposed are in effect:

(A) The public benefit anticipated as a result of enforcing or administering the rules as proposed will be a reduction of the probability of CWD being spread from locations where it might exist and an increase in the probability of detecting CWD if it does exist, thus ensuring the public of continued enjoyment of the resource and also ensuring the continued beneficial economic impacts of hunting in Texas.

(B) There could be adverse economic impact on persons required to comply with the rules as proposed. Such impacts would be identical to those described in the analysis of the rules’ potential effect on small businesses, microbusinesses, and rural communities elsewhere in this preamble.

(C) Under the provisions of Government Code, Chapter 2006, a state agency must prepare an economic impact statement and a regulatory flexibility analysis for a rule that may have an adverse economic effect on small businesses, micro-businesses, and rural communities. As required by Government Code, §2006.002(g), in April 2008, the Office of the Attorney General issued guidelines to assist state agencies in determining a proposed rule’s potential adverse economic impact on small businesses. These guidelines state that “[g]enerally, there is no need to examine the indirect effects of a proposed rule on entities outside of an agency’s regulatory jurisdiction.” The guidelines state that an agency need only consider a proposed rule’s “direct adverse economic impacts” to small businesses and micro-businesses to determine if any further analysis is required. The guidelines also list examples of the types of costs that may result in a “direct economic impact.” Such costs may include costs associated with additional recordkeeping or reporting requirements; new taxes or fees; lost sales or profits; changes in market competition; or the need to purchase or modify equipment or services.

For the purposes of this analysis, the department considers all deer breeders to be small or microbusinesses, which ensures that the analysis captures all deer breeders possibly affected by the proposed rulemaking. The department has determined that there is one deer breeding facility (other than the breeding facilities where CWD has been detected, which are prohibited from transferring deer under other rules) within proposed CZ 7. That deer breeding facility is currently designated MQ. Under the rule as proposed, that facility would be prohibited from transferring breeder deer outside the CZ; therefore, the economic impact to the breeder in question could be significant. Because the nature of the market for breeder deer is fluid and the department does not require sale prices of breeder deer to be reported, the department has no way to determine the exact value of lost sales to the deer breeder in question. Department records indicated the breeder in question has transferred an average of 53 deer per year, with an average of 17 of those deer being released to adjoining acreage (which would still be permitted). Therefore, the adverse economic impact to the breeder in question, based on the transfer history of the last five years, would be the value of 35 deer per year. There are three deer breeding facilities located within proposed new SZ 20 and one deer breeding facility located within proposed new SZ 21. All four facilities are currently designated NMQ and are prohibited from transferring deer. Thus, the zone designations will not result in adverse economic impacts to those facilities, as they cannot transfer deer under rules currently in effect. There are no deer breeding facilities within proposed CZ 8 or SZ 22.

The proposed amendment to §65.99 will result in adverse economic impacts to small businesses and microbusinesses affected by the rule. The amendment would require deer breeders who receive confirmation of a “suspect” test result from an ante-mortem test to euthanize the subject of the test within seven days of confirmation of CWD, submit post-mortem tissue samples within one business day of euthanasia, conduct daily inspections for additional mortalities, immediately report such mortalities, and collect and submit post-mortem tissue samples within one day of each mortality discovery. Deer breeders are already required under current rules to report all mortalities and to have them tested; therefore, the adverse economic impacts are the cost to euthanize a breeder deer and the cost of daily inspections. The cost of euthanizing a deer can range from very little (if the breeder dispatches a deer by firearm) to the costs associated with veterinary services, which the department estimates should not exceed $300. The costs associated with daily inspections is difficult to quantify, as breeder facilities vary in size and complexity; however, the department assumes that most breeding facilities require some sort of daily presence as a matter of routine operations. The department also notes that if the breeding facility is epidemiologically connected to another breeding facility, daily inspections are required under rules already in effect.

The department has determined that the proposed rules will not affect rural communities because the rules do not directly regulate any rural community.

(D) The department has not drafted a local employment impact statement under the Administrative Procedures Act, §2001.022, as the agency has determined that the rules as proposed will not result in direct impacts to local economies.

(E) The department has determined that Government Code, §2001.0225 (Regulatory Analysis of Major Environmental Rules), does not apply to the proposed rules.

(F) The department has determined that there will not be a taking of private real property, as defined by Government Code, Chapter 2007, as a result of the proposed rules. Any impacts resulting from the discovery of CWD in or near private real property would be the result of the discovery of CWD and not the proposed rules.

(G) In compliance with the requirements of Government Code, §2001.0221, the department has prepared the following Government Growth Impact Statement (GGIS). The rules as proposed, if adopted, will neither create nor eliminate a government program; not result in an increase or decrease in the number of full-time equivalent employee needs; not result in a need for additional General Revenue funding; not affect the amount of any fee; not create a new regulation; expand an existing regulation (by creating new areas subject to the rules governing CZs and SZs) and imposing new inspection and reporting requirements for deer breeding facilities where CWD is detected), but will otherwise not limit or repeal an existing regulation; neither increase nor decrease the number of individuals subject to regulation; and not positively or adversely affect the state’s economy.

4. Request for Public Comment.

Comments on the proposed rules may be submitted to Dr. J. Hunter Reed, Texas Parks and Wildlife Department, 4200 Smith School Road, Austin, Texas, 78744; (830) 890-1230 (e-mail: jhunter.reed@tpwd.texas.gov); or via the department’s website at www.tpwd.texas.gov.

5. Statutory Authority.

The amendments are proposed under the authority of Parks and Wildlife Code, Chapter 43, Subchapter C, which requires the commission to adopt rules to govern the collecting, holding, possession, propagation, release, display, or transport of protected wildlife for scientific research, educational display, zoological collection, or rehabilitation; Subchapter E, which requires the commission to adopt rules for the trapping, transporting, and transplanting of game animals and game birds, urban white-tailed deer removal, and trapping and transporting surplus white-tailed deer; Subchapter L, which authorizes the commission to make regulations governing the possession, transfer, purchase, sale, of breeder deer held under the authority of the subchapter; Subchapters R and R-1, which authorize the commission to establish the conditions of a deer management permit for white-tailed and mule deer, respectively; and §61.021, which provides that no person may possess a game animal at any time or in any place except as permitted under a proclamation of the commission.

The proposed amendments affect Parks and Wildlife Code, Chapter 43, Subchapters C, E, L, R, R-1, and Chapter 61.

6. Rule Text.
