Proposed Hazardous Duty Pay and Environmental Differential Pay for Prescribed Wildland Fire Activities

Content

ACTION:

Proposed rule.

SUMMARY:

The Office of Personnel Management is proposing to add prescribed (planned) wildland fire duties as covered activities triggering
payment of Hazardous Duty Pay for General Schedule (GS) employees and Environmental Differential Pay for Federal Wage System
(FWS) employees. The proposed new differentials would apply to GS and FWS employees participating as a member of a firefighting
crew engaged in activities on the fireline directly involving the implementation and control of prescribed wildland fires.
This rulemaking would authorize a 25 percent differential.

SUPPLEMENTARY INFORMATION:

The Office of Personnel Management (OPM) is proposing to establish new Hazardous Duty Pay (HDP) and Environmental Differential
Pay (EDP) categories at a 25 percent rate for Federal employees performing prescribed (planned) wildland fire activities.
HDP is a pay differential authorized by 5 U.S.C. 5545(d) and 5 CFR part 550, subpart I, for General Schedule (GS) (1) employees performing duties approved by OPM in Appendix A of the regulations that involve unusual physical hardship or hazard.
EDP is a pay differential authorized by 5 U.S.C. 5343(c)(4) and 5 CFR 532.511 for Federal Wage System (FWS) employees exposed
to working conditions or hazards that fall within one of the categories approved by OPM in Appendix A of 5 CFR part 532, subpart
E.

The Forest Service in the United States Department of Agriculture (USDA), which manages the National Forest System comprised
of 193 million acres of forest and grasslands, and the Office of Wildland Fire within the Department of the Interior (DOI),
which manages 2.6 million acres of forest and grasslands, requested OPM add prescribed wildland fire activities as new HDP
and EDP categories. “Prescribed fire” is the planned or controlled application of fire under specific conditions to restore
the health of ecosystems that depend on fire. (2) Prescribed wildland fire activities are not currently included as a covered category of work for HDP and EDP purposes. Based
on updated analyses, physical, chemical, and biological hazards associated with a prescribed fire may affect an employee's
short- and long-term safety and health in unavoidable ways, similar to the hazards found in a wildfire (i.e., an unplanned wildland fire incident) environment.

Certain firefighting work is listed as a hazardous duty in Appendix A to subpart I of part 550 and Appendix A to subpart E
of part 532 of title 5 of the Code of Federal Regulations qualifying for HDP and EDP. The language in the HDP regulations
includes “Forest and range fires” under the “Firefighting” category. A 25 percent hazard pay differential is authorized for
participating as a member of a firefighting crew in “fighting forest and range fires on the fireline.” The language in the
EDP regulations describes firefighting work as participating or assisting in firefighting operations where the firefighter
is “on the immediate fire scene and in direct exposure to the hazards inherent in containing or extinguishing fires.” Fighting
forest fires and range fires on the fireline is considered a “high degree” of hazard and provides for a 25 percent differential
rate. These existing HDP and EDP categories were specifically created to cover the fighting of wildfires and not activities
related to prescribed fires.

The proposed regulatory changes would provide for—

1. An HDP for GS employees and an EDP for FWS employees participating in prescribed wildland fire operations and engaged in
   activities on the fireline involving implementation and control of a prescribed wildland fire.

2. Assigning the rate of 25 percent for prescribed wildland fire activities for both HDP and EDP.

Generally, HDP is not payable to a GS employee when the hazardous duty has been taken into account in the classification of
the position encumbered by the employee. See 5 U.S.C. 5545(d)(1) and 5 CFR 550.904(a)-(b). However, in 2021, 5 U.S.C. 5545(d)(1)
was amended to allow, as a special exception, HDP for firefighters who are placed in a separate classification series based
on the primary duties of their position involving the prevention, control, suppression, or management of wildland fires—even
though firefighting duties are taken into account in the

  classification of their positions. (*See* Pub. L. 117-58, Nov. 15, 2021.) For GS employees in the 0456 Wildland Fire Management occupational series, this statutory
  exception supersedes OPM's current regulations at 5 CFR 550.904(a)-(b). Thus, a GS-0456 wildland firefighter can currently
  receive HDP for working on the fireline of a wildfire. Similarly, this proposed regulation would allow a GS-0456 wildland
  firefighter to be able to receive HDP for working on the fireline of a prescribed fire despite the classification of the employee's
  position. OPM is proposing to amend 5 CFR 550.904 to add a new paragraph (f) to clarify this statutory exclusion. (Note: The
  EDP authority does not include a similar classification restriction.)

Prescribed fire duties (e.g., ignition, fireline construction, holding, snag felling, mopup) expose employees to open flame, radiant and convective heat,
smoke, unstable terrain, fire-weakened trees, and other physical, chemical, and biological hazards during ignition and patrol
phases. Safety practices and Personal Protection Equipment (PPE), as described further in this notice, reduce—but cannot eliminate—these
risks. Agency data document thousands of smoke/inhalation exposures during prescribed fire operations (2018-2023) and fatalities
associated with prescribed burns (2003-2023). (3) Advances in research indicate declines in lung function and increases in biomarkers of systemic inflammation and oxidative
stress among wildland firefighters after shifts on both wildfires and prescribed fires. The International Agency for Research
on Cancer classifies occupational exposure as a firefighter as carcinogenic to humans. Congress has also provided presumptive
illness coverage for certain cancers and cardiac and pulmonary diseases for Federal wildland firefighters. (4)

OPM is responsible for establishing HDP categories for GS employees under 5 U.S.C. 5545(d) and EDP categories for FWS employees
under 5 U.S.C. 5343(c)(4). The GS HDP categories are contained in Appendix A to 5 CFR part 550, subpart I, and FWS EDP categories
are contained in Appendix A to subpart E of 5 CFR part 532. The proposal to add an EDP of 25 percent for prescribed wildland
fire activities was presented to the Federal Prevailing Rate Advisory Committee (FPRAC), the national labor-management committee
responsible for advising OPM on matters concerning the pay of FWS employees, at its July 18, 2024, meeting. (5) The Committee recommended this change by consensus.

After analyzing data presented by USDA and DOI and reviewing FPRAC's recommendation, OPM decided to propose an amendment to
current regulations to include a 25 percent differential for EDP applicable to the implementation and control of a prescribed
wildland fire when performed by FWS employees since these employees are exposed to most of the same physical, chemical, and
biological hazards that may affect an employee's short- and long-term health and safety as employees fighting wildfires. The
proposed language reviewed by FPRAC was “participating as a member of a firefighting crew, engaged in activities on the fire
line related to the preparation, implementation, and control on prescribed wildland fire.” The language approved by OPM in
this proposed regulation replaces “related to” with “directly involves” and does not include activities of “preparation” for
a prescribed fire, since the hazards justifying coverage are associated with management of an active fire and its aftermath
by employees working on the fireline, not preparatory activities before a fire has been ignited.

OPM's proposed regulations are consistent with Executive Order (E.O.) 14308, titled “Empowering Commonsense Wildfire Prevention
and Response,” (90 FR 23175) signed by President Donald J. Trump on June 12, 2025, directing USDA and DOI to consolidate their
wildland fire programs and recommend additional measures to modernize wildland fire prevention efforts.

The proposed change would apply the first day of the first pay period starting after the effective date of a final rule.

Description of the Hazardous Duty or Physical Hardship

Per USDA and DOI, (6) duties associated with prescribed fire activities include ignition, fireline construction, holding, snag felling, and mop-up.
As in wildfire suppression, prescribed burns expose firefighters to physical, chemical, and biological hazards with short-
and long-term health risks. Crews deploy along prepared control lines with standard gear—PPE (e.g., hard hats, fire-resistant clothing, gloves, boots), hand tools, chainsaws, and hoses—and ignite units using ground devices
(e.g., drip torches, Very pistols, fusees, propane or high-pressure torches) and/or aerial ignition (e.g., helicopters, drones). Working directly on the fireline next to a spreading fire, firefighters are exposed to open flame, radiant
and convective heat, and smoke throughout implementation. After ignition, patrol and mop-up can continue for days, involving
water or foam application, digging out hot material, and felling fire-weakened trees. Smoke exposure peaks during ignition
and early mop-up. From 2018-2023, Forest Service eSafety reports recorded 2,142 smoke or inhalation exposure incidents during
prescribed-fire operations. (7)

Information on Ways To Mitigate the Hazard

Prescribed fire and wildfire operations use similar hazard mitigation measures. Standard wildland safety practices—briefings
on assignments, hazards, weather, and unique risks; posting lookouts; use of PPE; and following established checklists and
avoidance procedures—reduce risk but cannot eliminate it. Any fire operation increases the risk of injury or illness, and
prescribed burns occur in inherently unpredictable conditions. Their hazards and required actions mirror those of wildfires—unstable
terrain, falling trees and rolling material, necessary proximity to fire, and chemical and biological exposures—so risks cannot
be fully controlled or mitigated.

The Degree to Which the Employee Is Exposed to Hazard or Physical Hardship

“Degree” in this case is characterized as a qualitative measure of magnitude, expressed over time. “Exposure” in this case
is characterized as any occurrence where an employee is directly affected by the hazard and is therefore subject to the consequences
of the hazard.

While conducting the implementation and patrol phase of prescribed fire operations, employees are exposed to variable degrees
of a discrete or cumulative number of hazards. Not all hazards that employees are exposed to can be fully mitigated. Specific
examples are described in the following table.

Job task	Definition	Hazards that cannot be fully mitigated
Firing/ignition operations	Ignition of burnable materials (fuels) with drip torches filled with a diesel/unleaded gasoline mixture, fusees, flare launchers,

           or other incendiary devices. How the burn is ignited (through firing patterns) may result in varying fire behavior and smoke
           production | *Physical Hazard* Working on slopes and uneven ground (Slips, trips, falls, ground collapse, stobs, stump holes with hot ash).Fire behavior that may lead to increased extreme temperatures.Working in and around fire weakened trees. *Chemical Hazard* Exposure to by-products of combustion (from burning vegetation and ignition devices).Exposure to silica (dirt, dust and ash).Exposure to engine fuel and exhaust. *Biological Hazard* Exposure to biological hazards (poison ivy/oak, animal and insect bites, fungal pathogens). |

| Holding | Monitor and patrol a section of the fireline (on wildfires and prescribed fires) and ensure that fire does not cross the fireline.
Firefighters performing holding can be instructed to stand along a fireline and watch for the fire escaping control lines
which can involve being in areas of high smoke and low visibility and around fire weakened trees | |
| Mop-up | Extinguish any burning or smoldering material by digging out the burning material or applying water to prevent rekindling
and improve the chances the fireline will hold the fire | |
| Patrolling | Inspect and monitor a fire perimeter to monitor fire conditions | |

Description of Hazardous Nature of Firefighter Duties and Working Conditions

During implementation and patrol, employees face multiple, sometimes cumulative hazards that cannot be fully mitigated. Smoke
exposure on both wildfires and prescribed fires is associated with reduced lung function, increased airway responsiveness,
and elevated biomarkers of systemic inflammation, oxidative stress, and urinary mutagenicity after shifts and across seasons.
Exposure assessments consistently detect hazardous air pollutants, including carcinogens. In 2022, the International Agency
for Research on Cancer (IARC) classified occupational exposure as a firefighter as carcinogenic to humans. (8)

An IARC working group did not differentiate between structural and wildland fire exposures and cancer risk, and many of their
studies that provided evidence of carcinogenicity were in wildland firefighters working on wildfires and prescribed fires
reporting increases in inflammation and oxidative stress. Congress likewise recognized these hazards in section 5305 (Fairness
for Federal Firefighters) of the James M. Inhofe National Defense Authorization Act of 2023, Public Law 117-263 (Dec. 23,
2022), which provides presumptive workers' compensation coverage under 5 U.S.C. 8143b for certain cancers and cardio-pulmonary
diseases associated with fire protection activities. In the first year of coverage under this Act, 29 Forest Service wildland
firefighters submitted claims to the Department of Labor, Office of Workers' Compensation Programs under section 5305. (9) Although the Occupational Safety and Health Administration (OSHA) has no prescribed fire specific- standard and the Forest
Service applies administrative controls and PPE (training, ignition-safety courses, contingency-based planning), these measures
cannot reduce risk below a significant level. The National Wildfire Coordinating Group Risk Management Committee reported
15 prescribed fire fatalities from 2003-2023. (10) Since 2019, Fire Aviation Management Risk Management data show prescribed-fire injuries range from treated-and-released to
fatal and, on average, occur with frequency and severity similar to large- fire suppression.

According to USDA and DOI, injury patterns are similar for large-fire and prescribed-fire operations, with fireline work accounting
for the largest share in both, but more heavily so during prescribed fires. In large-fire operations, roughly one-third of
injuries occur on the fireline, about one-quarter are environmental, around one-fifth are illness-related, and a smaller share
are tied to ground transportation, while aviation and other categories make up only a small fraction. In prescribed-fire operations,
fireline injuries make up the largest portion at just over 40 percent, followed by ground transportation at a little over
20 percent, with environmental injuries in the mid-teens, aviation near 10 percent, illness below that, and almost none in
the “other” category. The average injury severity is slightly higher for large fires than for prescribed fires, although the
overall severity levels are relatively close. (11)

The Wildland Fire Lessons Learned Center Incident Review Database (IRDB) (https://lessons.wildfire.gov/search-irdb) houses hundreds of reports, reviews, and lessons-learned documents, many of which discuss accidents on prescribed fires.
The examples included here reflect the interagency, collaborative nature of prescribed fire operations, as well as the wide
range of injuries—including fatal injuries—that firefighters can experience on prescribed fires.

The Degree to Which Control May Be Exercised Over the Physical Hardship or Hazard

Although it was previously opined that prescribed fires are planned and in “control,” this term has not been used by the wildland
fire community in public communications or Federal policy. Since 1995, (12) Federal policy has

  recognized prescribed fire—and, in 2009 guidance, [(13)]() planned fire—as the correct term for intentional fire use. In addition, the term “control[led] burn” is not found in the Publication
  Management System (PMS) 484—Prescribed Fire Planning and Implementation Procedures Guide or in the PMS 205 [(14)]() which is the inter-agency standard for wildland fire related definitions.

Within the wildland fire community, control refers to an end state of a wildfire or prescribed fire or to specific tactics/features
(e.g., “control line,” “natural control feature”), not to the operation itself. In short, “controlled fire” is a misnomer: any fire
on the landscape can exceed intended boundaries and is never fully within human control.

Standard safety practices—thorough briefings on hazards and weather, posting lookouts, and adherence to established checklists
and avoidance procedures—mitigate some risks. Nevertheless, any fire, prescribed or wildfire, increases the likelihood of
exposure, injury, and illness. Prescribed burns occur in an inherently unpredictable environment with limited ability to control
hazards. Required tasks—traversing unstable terrain, working in close proximity to flame, and exposure to chemical and biological
hazards—create conditions that cannot be fully mitigated or controlled. Coupled with recent research and congressional mandates
recognizing smoke exposure as a hazard, these realities justify additional HDP and EDP compensation for GS and FWS employees
engaged in prescribed fire operations.

Expected Impact of This Rule

A. Statement of Need

This proposed regulation is needed because there is currently pay disparity between FWS and GS employees performing prescribed
(planned) wildland fire activities and those working wildfire firelines. The purpose of these regulations is to achieve pay
parity for Federal employees conducting prescribed wildland fire activities and Federal employees performing duties involving
wildfires. As stated previously, while prescribed fire plans contain certain feasible mitigations, unavoidable hazards remain.
Because providing a 25 percent HDP/EDP differential only to Federal firefighters engaged in wildland fire activities could
potentially perpetuate a disparate compensation practice, the Federal Government is taking steps to address the compensation
policy for those Federal employees who are exposed to unusual health risks caused by working in close proximity to prescribed
wildland fires and that cannot be mitigated.

Lack of EDP and HDP compensation is also a persistent barrier in recruiting and retaining FWS and GS employees to carry out
prescribed-fire operations.

B. Impact

This proposed rule would provide a 25 percent HDP for GS employees and EDP for FWS employees participating in prescribed wildland
fire operations and engaged in activities on the fireline related to implementation and patrol of prescribed wildland fires.
The proposed changes would primarily apply to firefighters at USDA Forest Service and DOI. However, other agencies have advised
OPM that in limited situations they may also have employees temporarily assigned to prescribed wildland fire activities who
may meet the criteria for payment of the proposed 25 percent EDP or HDP differential. The proposed new differentials may apply
to employees performing qualifying prescribed wildland fire duties in agencies outside of USDA Forest Service and DOI. Decisions
on whether employees meet the criteria for application of the prescribed wildland fire differentials would be made by the
employing agencies.

Under 5 U.S.C. 5545(d) and 5343(c)(4), OPM has the authority and responsibility to establish and make changes to HDP and EDP
categories to provide additional compensation to GS and FWS employees. Any changes to the HDP and EDP schedules in title 5
will have the long-term effect of increasing pay for Federal employees in affected locations. OPM expects this rulemaking
to impact approximately 10,000 GS employees and 2,500 FWS employees at USDA and DOI. Considering the number of employees affected,
OPM does not anticipate that this proposed rule will substantially impact local economies or have a large impact in local
labor markets.

The Length of Time During Which the Duty Will Continue To Exist

Within known technological limits, the duty of prescribed fire as currently implemented by the U.S. Federal Government has
no foreseeable point in time in which it will cease to exist. The role of prescribed fire within natural ecosystems has been
established by over 100 years of relevant science as the only practical mitigation and restoration tool available to professional
land managers. The USDA Forest Service Wildfire Crisis Strategy Implementation Plan, (15) the National Wildland Fire Cohesive Strategy, (16) and the Report of the Wildland Fire Mitigation and Management Commission (17) all support expanding the spatial scale of prescribed fires. As such, there is no known end-state to the hazards associated
with prescribed fire. The overall magnitude of exposures to prescribed fire-related hazards are likely to increase over time.

C. Costs

Utilizing current GS and FWS pay rates, USDA has estimated that providing HDP and EDP for prescribed fires would cost the
Government $20 million, while the DOI has estimated it to be $12.5 million in FY2026.

All Forest Service employees engaged in prescribed fires and wildfire response are paid from a single salary line for firefighters.
The Forest Service sees on average roughly 80 percent of the operational firefighters participating in prescribed fire in
any given fiscal year. The cost estimate of $20 million for the Forest Service for FY26 is based on approximately 250 hours
of prescribed fire operations. These numbers can fluctuate heavily depending on burn conditions, weather, frequency of wildfires
(which take priority), etc.

Using the FY25 total as the baseline, DOI compared FY25 prescribed fire accomplishments (acres treated) with draft FY26 and
FY27 targets, which are about 10 percent higher than FY25 accomplishments. To accommodate both the expected increase in work
and labor costs—including a 1 percent pay increase from FY25 to FY26, DOI increased the FY26 Hazard Pay (“H-pay”) estimate
by 11 percent over FY25 actual obligations, resulting in $8.95 million, rounded up to $9.0 million. For FY27, DOI increased
the estimate from $9.0 million to $9.5 million (a 5.6 percent increase) to account for

  potential additional labor cost increases and further increases in targets and accomplishments, reflecting DOI leadership
  and administration priorities around fuels management and the expectation of a departmental performance target in the FY26/FY27
  timeframe. Note that these costs to the Government are considered transfers rather than societal resource costs.

If this rulemaking is finalized, agency payroll providers will need to properly assign EDP and HDP time and attendance, payroll,
and/or other internal codes and documentation necessary to ensure payment of the differential for qualifying work. Payroll
providers may establish their own payroll codes as needed, as long as they report the required data based on OPM's established
Enterprise Human Resources Integration data elements. This is not anticipated to be a significant additional cost burden or
to require additional funding as agency payroll systems are often updated as a routine business matter.

D. Benefits

This proposed rule has important benefits. As already stated, the hazards faced by FWS and GS employees conducting prescribed
fire activities mirror those faced by FWS and GS employees managing wildfires; however, employees conducting prescribed fire
activities do not receive any differential in pay. Recent research has heightened awareness of smoke and other environmental
risks during prescribed burns. Providing commensurate pay for prescribed fire operations will help with recruiting and retaining
FWS and GS employees. Providing the differential pay also shows a recognition of the risks associated with the position and
places a higher value on the needed service.

E. Alternatives

OPM considered not providing differential pay and, instead, allowing Federal agencies to rely on their discretionary authority
to provide pay and leave flexibilities to address significant recruitment and retention problems. However, pay and leave flexibilities
would not solve the underlying pay inequities between Federal employees exposed to similar types of fire hazards because such
incentives are optional, uneven, and not tightly tied to hazard exposure. Two employees performing the same risky work may
still end up paid very differently depending on location, local management decisions, or budget.

OPM also considered providing a lower percentage than a 25 percent differential, however this approach would underappreciate
the hazards involved in prescribed fire activities, which are equivalent to wildland fire hazards.

Request for Comments

OPM requests public comments from local businesses on the implementation and impacts of USDA and DOI paying an additional
compensation of 25 percent HDP to GS employees and EDP to prevailing rate employees participating in prescribed wildland fire
operations and whether these changes would be likely to affect them.

Regulatory Compliance

A. Regulatory Review

OPM has examined the impact of this rule as required by E.O.s 12866 and 13563, which direct agencies to assess all costs and
benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize
net benefits (including potential economic, environmental, public, health, and safety effects, distributive impacts, and equity).
A regulatory impact analysis must be prepared for rules that have an annual effect on the economy of $100 million or more
or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment,
public health or safety, or State, local, or tribal governments or communities. This rulemaking does not reach that threshold
but has otherwise been designated as a “significant regulatory action” under section 3(f) of E.O. 12866. This rule is not
expected to be considered an E.O. 14192 regulatory action because it imposes no more than de minimis costs.

B. Regulatory Flexibility Act

The Director of OPM certifies that this rulemaking will not have a significant economic impact on a substantial number of
small entities.

C. Federalism

This regulation will not have substantial direct effects on the States, on the relationship between the National Government
and the States, or on distribution of power and responsibilities among the various levels of government. Therefore, in accordance
with E.O. 13132, the Director of OPM certifies that this proposed rule does not have sufficient federalism implications to
warrant preparation of a Federalism Assessment.

D. Civil Justice Reform

This rulemaking meets the applicable standard set forth in section 3(a) and (b)(2) of E.O. 12988.

E. Unfunded Mandates Act of 1995

Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) requires that agencies assess anticipated costs and benefits
before issuing any rule that would impose spending costs on State, local, or tribal governments in the aggregate, or on the
private sector, in any 1 year of $100 million in 1995 dollars, updated annually for inflation. That threshold is currently
approximately $206 million. This rulemaking will not result in the expenditure by State, local, or tribal governments, in
the aggregate, or by the private sector, in excess of the threshold. Thus, no written assessment of unfunded mandates is required.

F. Paperwork Reduction Act

This rulemaking does not impose any reporting or record-keeping requirements subject to the Paperwork Reduction Act, as amended
(44 U.S.C. Chapter 35).
