EEOICPA — Energy Employees Occupational Illness Compensation

The Energy Employees Occupational Illness Compensation Program Act (EEOICPA) provides $150,000 lump-sum payments plus lifetime medical benefits to former nuclear weapons workers — and their survivors — who developed cancer, beryllium disease, or silicosis from working at Department of Energy facilities. Congress passed the law in 2000 acknowledging what the government had known for decades: that people who built and tested America's nuclear arsenal were exposed to radiation and toxic chemicals, got sick, and were never compensated. Since then, the program has paid out over $27 billion in compensation and medical benefits, approving more than 188,000 claims covering roughly 141,000 employees and their families.

Implementing Regulations

The Department of Labor regulations implementing EEOICPA live at 20 CFR Part 30 — Claims for Compensation Under the Energy Employees Occupational Illness Compensation Program Act. With 8 subparts and 161 sections, Part 30 is the complete procedural backbone of the program: how to file, what evidence is required, how eligibility is adjudicated, what medical benefits are available, and how medical providers participate. Key provisions:

• § 30.100 — Filing deadline: claims may be filed at any time; there is no statute of limitations for EEOICPA claims
• § 30.102 — Form EE-1 (employee claim) and Form EE-2 (survivor claim) — the official filing forms; electronic filing available through DEEOIC's Energy Portal
• § 30.107 — Form EE-5 — DOE employment verification form; completed by the claimant's former employer or DOE and submitted to establish covered employment during qualifying periods at a covered facility
• § 30.110 — Evidence standards: claimant bears burden of proof by a preponderance of the evidence; DEEOIC has authority to develop the record, including requesting additional evidence and conducting investigations
• § 30.205 — Covered employment verification: DEEOIC checks the Site Exposure Matrices (SEM) database to identify covered toxic substances and exposure pathways for the claimant's specific job duties and work locations
• § 30.300 — Recommended decisions: Claims Examiners issue recommended decisions; claimants have 60 days to object before a Final Decision issues
• § 30.310 — Final decisions and appeal rights: claimants may appeal Final Decisions to the DEEOIC district office and ultimately to the Employees' Compensation Appeals Board (ECAB)
• § 30.400 — Medical benefits: DEEOIC pays for all medical treatment "reasonably related" to the accepted occupational illness; no copays, deductibles, or coverage limits apply
• § 30.402 — Choice of physician: claimants may select their own treating physician; DEEOIC authorizes and pays providers enrolled in the program's billing system
• § 30.500 — Survivor hierarchy: eligible survivors in order of priority are spouse, children (including adopted and stepchildren), parents, siblings; a deceased employee's estate does not inherit the claim
• § 30.600 — Part E impairment ratings: impairment-based compensation under Part E is calculated using the AMA Guides to the Evaluation of Permanent Impairment (Sixth Edition); physicians must be DEEOIC-approved for impairment rating examinations
• § 30.700–30.725 — Special provisions: Section 5(c) election (if a claimant previously received state workers' compensation, the federal benefit offsets the prior payment); overpayment recovery procedures; subrogation rights against third parties
• §§ 30.800–30.825 — Medical provider requirements (the largest subpart, 26 sections): providers must enroll with DEEOIC's billing contractor; billing must use specified procedure codes; providers found to have billed fraudulently are excluded from participation

The Part 30 framework runs on a non-adversarial model: DEEOIC claims examiners are required to develop the evidentiary record, assist claimants in gathering evidence, and weigh evidence in the claimant's favor when the record is ambiguous. This is intentional — Congress designed the program specifically to make compensation accessible to aging and ill workers rather than creating an adversarial system they would need to litigate. DOL Resource Centers funded under § 7384s(d) provide free case assistance to claimants navigating Part 30 procedures.

42 CFR Part 82 — Methods for Conducting Dose Reconstruction Under EEOICPA (24 sections — NIOSH implementing regulation establishing the scientific methods for estimating radiation doses received by nuclear weapons workers when records are incomplete; works in conjunction with Part 81 to determine whether a cancer claim is compensable):

• § 82.2 — Basics: dose reconstruction means characterizing the radiation environments in which a worker was employed and estimating doses to specific organs and tissues from each type of radiation encountered (external gamma, neutron, internal alpha/beta from inhaled or ingested radionuclides); the goal is a realistic-but-claimant-favorable estimate of annual dose at each cancer site

• § 82.10 — Overview: NIOSH receives claims packages from DOL; reviews employment records from DOE, collects bioassay results, reviews facility dosimetry records, and interviews available coworkers; the result is a written dose reconstruction document provided to both the claimant and DOL; DOL then applies IREP software (under Part 81) to convert the reconstructed dose into a probability of causation

• § 82.13–82.14 — Information sources: NIOSH uses individual monitoring records (film badges, TLDs, bioassay results); facility-level records (area monitoring, air sampling, job task descriptions); published epidemiological studies of radiation workers at the same site; and coworker dose data when individual records are unavailable; NIOSH maintains site-specific technical documents (Site Profile Documents) for major DOE facilities

• § 82.15–82.16 — Missing dose methodology: NIOSH identifies gaps in a worker's monitoring records; for missing periods, NIOSH adds "missed dose" estimates based on comparable workers' dosimetry during the same period using a claimant-favorable approach — the maximum recorded comparable dose, not an average

• § 82.17 — Coworker models: when individual monitoring is inadequate, NIOSH uses coworker models derived from workers with similar job codes at the same facility; where facility coworker data is unavailable, regional or national models substitute; the hierarchy of substitutes is designed to favor the claimant when uncertainty is high

• § 82.18–82.19 — Internal dose and uncertainty: NIOSH calculates internal dose from inhaled/ingested radionuclides based on bioassay data and biokinetic models; each annual dose estimate is characterized by an uncertainty distribution rather than a single value; this uncertainty distribution feeds into IREP's 99th-percentile probability of causation calculation

  NIOSH has developed Site Profile Documents (SPDs) for major facilities (Hanford, Rocky Flats, Oak Ridge, Savannah River) that describe the radiation environments and monitoring practices at each site across different time periods — the technical foundation for coworker modeling. The claimant-favorable missed-dose methodology was deliberately designed by Congress to compensate workers even when records are inadequate. No major recent rulemaking — 42 CFR Part 82 was finalized in 2002 (67 FR 22296); NIOSH updates methods through Site Profile Documents and Special Exposure Cohort petitions rather than rulemaking.

42 CFR Part 81 — Guidelines for Determining Probability of Causation Under EEOICPA: the NIOSH/HHS implementing regulation for how NIOSH reconstructs radiation doses and calculates cancer causation probability for Part B claims:

• § 81.0–81.1 — Background and purpose: EEOICPA Part B provides compensation for cancer to covered nuclear workers if their cancer was "at least as likely as not" caused by occupational radiation exposure — meaning a ≥50% probability of causation (PoC); where records are inadequate, NIOSH reconstructs the worker's radiation dose using facility records, bioassay data, job history, and coworker data; NIOSH then uses the Interactive RadioEpidemiological Program (IREP) software to estimate PoC based on the reconstructed dose, the specific cancer type, the worker's age, sex, and year of cancer onset

• § 81.10 — Cancer risk assessment models (IREP): the PoC calculation uses cancer-type-specific risk models developed from the epidemiology of atomic bomb survivors, radiation workers, and medical irradiation populations; IREP converts the reconstructed dose into a site-specific excess relative risk (ERR) that, combined with background cancer rates, yields the PoC estimate; IREP is a publicly accessible computational tool — claimants and their advocates can run their own IREP calculations to check NIOSH's work

• § 81.20 — Rounding of probability calculations: PoC values are rounded to the nearest whole number (e.g., a calculated PoC of 49.6% rounds to 50%, which meets the ≥50% threshold); this rounding provision has been significant in practice — many borderline claims are resolved by the rounding rule

• Uncertainty percentile: IREP calculates a PoC distribution reflecting uncertainty in the dose reconstruction and risk models; a worker qualifies for compensation if the 99th percentile of the PoC distribution (upper confidence bound) reaches 50% — meaning the probability of causation reaches 50% even under favorable assumptions about radiation dose and risk; this "99th percentile" rule gives workers the benefit of the doubt in cases of substantial uncertainty and has enabled compensation for many workers with reconstructed doses that might not reach 50% at the central estimate

  The Part 81 guidelines are particularly important for workers at facilities with poor dosimetry records, where reconstructed doses necessarily rely on assumptions and coworker modeling. Claimants can request a "companion case assessment" using a coworker with better-documented exposure at the same facility to establish a floor for their own dose estimate. Part 81's probability methodology has been reviewed and defended in administrative proceedings and federal court; while some claimants and advocates argue that the threshold should be lower than 50%, the ≥50% standard has been consistently upheld. Recent rulemakings: 72 FR 23204 (April 2007) — final rule establishing Part 81 PoC guidelines and IREP procedures.

Recent rulemakings: 84 FR 3053 (January 2019) was the most significant recent amendment to Part 30, updating the impairment rating methodology, clarifying survivor eligibility rules, and revising medical provider billing requirements to align with updated procedure coding standards.

The companion statute — the Radiation Exposure Compensation Act (RECA) — is administered separately by DOJ under 28 CFR Part 79. While EEOICPA covers employees at DOE facilities and atomic weapons employers, RECA covers four different populations exposed to radiation from Cold War-era nuclear weapons testing and uranium extraction:

• § 79.3 — Compensable claim categories: Part 79 implements four eligibility categories — (1) downwinders with leukemia; (2) downwinders with one of 17 specified cancers; (3) onsite participants (military and civilian personnel present at above-ground nuclear test sites); (4) uranium miners, millers, and ore transporters from specified states (AZ, CO, ID, NM, NV, OR, SD, TX, UT, WA, WY, and Navajo Nation lands)
• §§ 79.10–79.16 (Subpart B) — Leukemia claims: to qualify, a claimant must have been physically present in a specified "affected area" during the period of atmospheric nuclear testing before January 31, 1963; developed leukemia more than two years after first exposure; and have medical documentation of the diagnosis; the DOJ program presumes the onset date is the diagnosis date
• §§ 79.20–79.27 (Subpart C) — Downwinder specified disease claims: covers 17 types of cancer (including thyroid cancer, breast cancer, leukemia, and cancers of the lung, stomach, and pharynx); the claimant must have resided or worked full-time in an "affected area" for at least two years before January 1, 1971, and the cancer must have developed more than five years after first exposure
• §§ 79.30–79.35 (Subpart D) — Onsite participant claims: covers military and civilian personnel present at the Nevada Test Site, Pacific Proving Ground, or other designated atmospheric test locations before January 1, 1963; the claim requires documentation of onsite presence (military records, DoD contractor records) and a qualifying specified disease
• §§ 79.42–79.46 (Subpart E) — Uranium miner claims: miners employed in specified states who were exposed to at least 40 Working Level Months (WLMs) of radiation and developed primary lung cancer or a nonmalignant respiratory disease (silicosis, fibrosis, chronic obstructive pulmonary disease); the DOJ resolves all reasonable doubt in the claimant's favor — the same claimant-favorable standard as EEOICPA Part 30
• §§ 79.52–79.57 (Subpart F) — Uranium miller claims: similar to miner claims but for workers at uranium ore milling facilities; covered diseases include primary lung cancer, nonmalignant respiratory disease, primary renal cancer, and chronic renal disease
• §§ 79.62–79.68 (Subpart G) — Ore transporter claims: workers who transported uranium ore in specified states; covered diseases parallel miner eligibility

RECA compensation amounts are fixed by statute (not Part 79). RECA was reauthorized as part of the One Big Beautiful Bill Act (Pub. L. 119-21, enacted July 4, 2025), which expanded eligibility and increased award amounts: Downwinders and Onsite Participants now receive $100,000 (up from $50,000 and $75,000 respectively); uranium miners, millers, and ore transporters remain at $100,000. The reauthorization expanded Downwind eligibility to cover the entire states of Idaho, Utah, and New Mexico (capturing Trinity test downwinders), authorized resubmission of previously denied claims (up to three times), and authorized supplemental claims for those who received compensation before enactment. Claims must be filed by December 31, 2027, and the Trust Fund authority runs through December 31, 2028. RECA is a lump-sum payment program — there are no medical benefits and no impairment ratings, unlike EEOICPA. The DOJ RECA Program in Landover, MD processes claims.

Who EEOICPA Covers

The program covers three main populations:

Part B — The Core Program:

Covered beryllium employees — Anyone employed by the Department of Energy (or a DOE contractor/subcontractor) or by an atomic weapons employer who was exposed to beryllium during production or testing. Beryllium was widely used in nuclear weapons components and causes a debilitating lung disease (chronic beryllium disease or CBD) in a fraction of those exposed. Workers with confirmed beryllium sensitivity receive monitoring; those who progress to chronic beryllium disease receive the full $150,000.

Covered employees with cancer — Workers at DOE facilities who developed one of the designated radiation-related cancers (radiogenic cancers). The challenge is proving that a cancer was caused by radiation exposure rather than background rates. For workers in the Special Exposure Cohort — those who worked at specific facilities during specific periods where records are insufficient to reconstruct individual doses — the cancer is presumed to be work-related without requiring dose reconstruction. NIOSH maintains the SEC list; workers can petition to add new classes.

Chronic silicosis — Workers at DOE test sites (primarily Nevada Test Site) who developed chronic silicosis from silica dust exposure are also covered.

Part E — DOE Contractor Employees:

Part E covers a broader population: DOE contractor employees who contracted any covered illness (not just the three diseases above) through exposure to a toxic substance at a DOE facility. Compensation under Part E varies based on the extent of impairment and lost wages — it's not a fixed $150,000. Workers can potentially recover under both Part B and Part E for the same illness.

How It Affects You

If you worked at a DOE nuclear weapons facility — Los Alamos, Hanford, Oak Ridge, Rocky Flats, Savannah River, Nevada Test Site, or any of the dozens of NNSA nuclear weapons production and testing sites — you may be eligible. The Department of Labor's site exposure matrices can help identify whether your specific work activities, location, and time period map to covered exposures. Claims are filed with DOL, and assistance is available from Resource Centers that DOL funds specifically to help workers navigate the process.

If a family member who worked at a DOE facility has died, you may be eligible as a survivor. The same $150,000 benefit is payable to surviving spouses, children, or parents. There's no statute of limitations — you can file even decades after your family member's death, as long as you can document the employment. Veterans whose exposure occurred in military nuclear service should also look at VA disability compensation, which runs on a separate track.

If you're a nuclear worker who has developed cancer: Dose reconstruction is the central challenge. NIOSH reconstructs the radiation dose you received based on facility records, monitoring data, and modeling. If the reconstructed dose suggests a ≥50% probability of causation — meaning it's at least as likely as not that radiation caused your cancer — you qualify for the $150,000 lump sum plus medical benefits. Certain cancers with higher radiation sensitivity (leukemias, thyroid cancer, bone cancer) reach the 50% threshold more easily. Workers in the Special Exposure Cohort (SEC) — those at 22 designated facilities where adequate dosimetry records are unavailable — bypass dose reconstruction entirely and qualify automatically for 22 specific cancers. Check whether your facility is on the SEC list before requesting dose reconstruction.

If you've already received state workers' compensation for the same illness: Any EEOICPA payment is offset by prior state workers' comp payments for the same illness — you generally can't double-collect. But the EEOICPA benefit ($150,000 lump sum) is often significantly larger than what state workers' comp paid, so it's worth filing even if you received a prior settlement. Contact a DOL Resource Center (funded specifically to help workers navigate EEOICPA at no charge to the worker) to evaluate whether a claim makes sense given your prior compensation history.

State Variations

EEOICPA is a federal program that runs entirely through DOL and is not affected by state workers' compensation systems, except through the offset rules. Some states have their own compensation programs for nuclear workers that may interact with EEOICPA. State workers' compensation may have covered some of the same workers for similar injuries, and those payments reduce (but do not eliminate) EEOICPA benefits.

Pending Legislation

Periodic proposals to expand the Special Exposure Cohort, add facilities to the covered list, or streamline the dose reconstruction process have bipartisan support. See also Black Lung Benefits for a comparable occupational illness compensation program in the mining sector, and Longshore and Harbor Workers' Compensation for the adjacent federal maritime workers' comp regime. Uranium miners are covered under the separate Radiation Exposure Compensation Act (RECA), which was reauthorized and substantially expanded by the One Big Beautiful Bill Act (Pub. L. 119-21) on July 4, 2025. No major EEOICPA structural changes pending as of 2026.

Recent Developments

• Advisory Board expanded Special Exposure Cohort (SEC) to additional cold war weapons facilities: The Advisory Board on Radiation and Worker Health (ABRWH) has continued processing SEC petitions from worker groups at facilities where dose reconstruction is impossible due to inadequate historical dosimetry records. SEC designation is significant: Part B cancer compensation becomes near-automatic for class members, because SEC workers are presumed to have received sufficient radiation without needing individual dose reconstruction. Recent SEC additions include additional cohorts at Paducah (Kentucky), Gaseous Diffusion Plant workers, and former Portsmouth (Ohio) facility workers — expanding the universe of workers who can qualify without the slow individual dose-reconstruction process.
• Uranium miners and millers in western states face persistent claim backlogs: Workers from the uranium mining boom in Colorado, New Mexico, Utah, and Arizona — primarily Navajo Nation members and other tribal workers from Cold War-era extraction operations — continue to file EEOICPA claims decades after exposure. The Radiation Exposure Compensation Act (RECA), a companion statute, was reauthorized and expanded under the One Big Beautiful Bill Act (Pub. L. 119-21, July 4, 2025) after lapsing in June 2024; the reauthorization expanded Downwind eligibility to all of Idaho, Utah, and New Mexico (capturing Trinity test downwinders) and increased award amounts to $100,000 across categories. EEOICPA Part B and E remain available to these workers in parallel with the revived RECA program.
• DOL's Office of Workers' Compensation Programs processing times improving but still long: EEOICPA claims — particularly Part B claims requiring dose reconstruction by NIOSH — average 2–4 years from filing to final determination. DOL has implemented process improvements and increased staffing for dose reconstruction reviews; NIOSH's Interactive RadioEpidemiological Program (IREP) software has been updated to improve dose estimates. As of late 2024, the program has paid over $27 billion in compensation and medical benefits since 2001, covering more than 188,000 approved claims — a significant but still incomplete accounting of Cold War nuclear production's human cost.
• Beryllium disease claims continue to drive 2025-2026 advocacy: Chronic beryllium disease claims — which require proving sensitization through a Beryllium Lymphocyte Proliferation Test (BeLPT) — remain a focus of DOL rulemaking. Advocacy groups representing DOE contractor workers have pushed for expanded presumptions for beryllium and silica exposures. With RECA reauthorization completed in July 2025, attention has shifted to whether EEOICPA's coverage of radiation workers is complete — particularly for workers at non-DOE sites, commercial nuclear facilities, and research institutions where Cold War weapons work occurred but DOE contractor status is disputed.
