OSHA vs. DOE Regulation at Privatized Facilities: Your 29 CFR vs. 10 CFR 851 Crosswalk

Federal contractor HSE directors navigating the April 2026 OSHA-DOE MOU: jurisdiction, penalties, and compliance gaps at M&O vs. privatized DOE sites.

by iSi Environmental

On April 17, 2026, the Occupational Safety and Health Administration and the Department of Energy formalized a jurisdictional shift that rewrites the regulatory playbook for federal contractors. The addendum to their 1992 Memorandum of Understanding transferred occupational safety and health authority from DOE to OSHA and state regulators at four major DOE sites: Idaho National Laboratory, Hanford, Nevada National Security Site, and Savannah River. For HSE directors managing contractor operations across multiple DOE locations, this means one critical reality: which regulation governs your site has just changed—and the compliance obligations, penalties, and enforcement processes are fundamentally different.

This article is a crosswalk. It explains what 10 CFR Part 851 (DOE’s Worker Safety and Health Program) requires versus 29 CFR (OSHA’s standards), which contractor categories fall under which rule, what the 2026 enforcement picture looks like, and what HSE decisions need to happen now.

What Changed on April 17, 2026?

The April 2026 OSHA-DOE MOU addendum clarifies that certain “Project Parcels”—parcels of DOE-owned land leased or operated by private entities not performing work for DOE—now fall under OSHA and state-plan jurisdiction instead of DOE’s. The critical threshold is radiation exposure: if employees can expect less than 25 millirems per year (mrem/yr) average exposure from DOE sources, the facility is treated as privatized and OSHA/state-plan standards apply. If exposure exceeds this, DOE retains jurisdiction.

The four sites affected:

  • Idaho National Laboratory: Project Parcels now fall under federal OSHA
  • Hanford Site (Washington): Project Parcels now under Washington State Department of Labor & Industries (DOSH)
  • Nevada National Security Site: Project Parcels now under Nevada state plan
  • Savannah River Site (South Carolina): Project Parcels now under South Carolina state plan

What did NOT change: Management & Operations (M&O) contractors and their subcontractors performing work on behalf of DOE at traditional DOE facilities remain under 10 CFR 851. Examples: Hanford Environmental Health Foundation managing the M&O contract, cleanup contractors remediating legacy contamination, construction crews hired by the M&O contractor for facility upgrades. These contractors still follow DOE rules, DOE penalties apply, and DOE’s Office of Enterprise Assessments conducts investigations.

The complexity: a subcontractor working on the same DOE site but assigned to a privatized parcel must switch compliance posture mid-project. This is where most HSE breakdowns occur.

The Regulatory Architecture: 10 CFR 851 vs. 29 CFR

10 CFR Part 851: DOE’s Worker Safety and Health Program

10 CFR 851 applies to DOE contractors and subcontractors at GOCO (Government-Owned, Contractor-Operated) facilities where DOE retains regulatory authority under section 4(b)(1) of the Atomic Energy Act. DOE chose to regulate its contractor workforces directly rather than rely on OSHA, citing unique hazards (nuclear materials, classified work, radiological exposure).

What 10 CFR 851 requires:

  1. Preapproval of written program. Contractors must submit a Worker Safety and Health Program to the DOE Field Element Head for approval before work begins. No work proceeds without written approval. (29 CFR requires no such preapproval; contractors develop programs and adjust as inspections warrant.)

  2. Mandatory functional areas. Contractors must implement programs across nine safety disciplines:

    • Construction safety (29 CFR 1926 adopted by reference, plus DOE enhancements)
    • Fire protection (NFPA codes + DOE specifics)
    • Firearms and explosives safety (DOE-only)
    • Pressure equipment safety (ASME standards + DOE)
    • Electrical safety (29 CFR 1910 Subpart S + DOE)
    • Industrial hygiene (ACGIH TLVs as baseline—often more stringent than OSHA’s PELs)
    • Occupational medicine and biological monitoring
    • Biological safety (NIH + DOE guidelines)
    • Motor vehicle safety

    (29 CFR does not prescribe functional areas; contractors self-select based on hazards and industry norms.)

  3. Incorporation of OSHA standards by reference, with exceptions. 10 CFR 851 adopts 29 CFR 1910, 1915, and 1926, BUT excludes specific OSHA rules on beryllium (29 CFR 1910.1024), ionizing radiation (29 CFR 1910.1096), and some air contaminant limits. This creates a subtle trap: contractors must follow OSHA standards unless DOE says otherwise—and DOE’s carve-outs are stricter, not looser.

  4. Accountability hierarchy. Contractor management at covered workplaces must establish written safety policy, goals, objectives; assign accountability; use qualified worker safety and health staff; and maintain DOE-approved procedures. (29 CFR requires “responsible parties” and hazard assessments but is less prescriptive about organizational structure.)

  5. Incident investigation with DOE participation rights. Contractors must investigate occupational incidents (injuries, near-misses, property damage). DOE retains the right to investigate independently or jointly. Investigation reports must be provided to DOE within 30 days. (OSHA can only inspect and investigate if invited or if OSHA has jurisdiction; at DOE sites under DOE authority, OSHA cannot unilaterally investigate.)

  6. Continuous compliance documentation. Contractors must maintain records of hazard assessments, incident investigations, corrective actions, training, industrial hygiene monitoring, occupational medicine data. DOE assessors review these during facility evaluations. (29 CFR mandates OSHA 1904 recordkeeping for injuries/illnesses and specific standard records, but not a comprehensive program file.)

29 CFR (OSHA Standards): The Privatized Facility Baseline

29 CFR comprises OSHA’s general industry standards (1910), shipyard standards (1915), and construction standards (1926). At privatized DOE parcels—and at any non-DOE worksite—these are the controlling regulations.

What 29 CFR requires:

  1. Hazard assessment and control. Employers must provide a workplace free from recognized hazards causing or likely to cause death or serious harm (General Duty Clause, Section 5(a)(1) OSH Act). Specific standards address electrical, fall, confined space, hazard communication, PPE, noise, and hundreds of industrial hazards.

  2. No preapproval gate. Contractors need not submit programs for OSHA approval. OSHA discovers hazards through scheduled inspections, complaint investigations, or referrals. Corrective action is negotiated post-inspection or adjudicated before the Occupational Safety and Health Review Commission (OSHRC) if contested.

  3. Standard-specific compliance. Contractors must comply with applicable 29 CFR sections relevant to their operations (e.g., construction firms comply with 1926; general manufacturing with 1910). There is no “one size fits all” program requirement as in 10 CFR 851.

  4. Injury and illness recordkeeping. 29 CFR 1904 requires tracking and reporting of occupational injuries and illnesses. Log entries, annual summaries, and OSHA Form 300 (or electronic equivalent) are required. (10 CFR 851 requires OSHA 1904 compliance plus additional DOE-specific documentation.)

  5. OSHRC appeal process. If an employer contests a citation, the case is adjudicated before an independent commission (OSHRC). Employers have the right to counsel, discovery, and appeal. This process can take months to years. (10 CFR 851 has no equivalent appeal mechanism; DOE Final Notices of Violation are enforceable through contract action, fee reduction, or suspension—no external board reviews DOE decisions.)

  6. State-plan variants. In state-plan states (including Washington, Tennessee, New Mexico), state OSHA agencies enforce equivalent or more stringent standards. Penalties may differ; some states impose additional requirements not in federal 29 CFR.

Who Falls Under Which Rule? A Contractor Tier Breakdown

Tier 1: M&O Contractors at Traditional DOE Sites (10 CFR 851)

Who: Prime contractors managing major DOE facilities (e.g., Hanford Environmental Health Foundation at Hanford; Consolidated Nuclear Security, LLC at Y-12 and Pantex)

Sites: All traditional DOE M&O work—Oak Ridge National Laboratory, Paducah uranium enrichment plant, Portsmouth uranium enrichment plant, Savannah River Site (outside leased parcels), Hanford (outside Project Parcels), Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Sandia National Laboratories, WIPP (Waste Isolation Pilot Plant), Nevada National Security Site (outside leased parcels), Idaho National Laboratory (outside leased parcels)

What applies: 10 CFR 851 entirely. Contractors submit Worker Safety and Health Programs for DOE approval, implement the nine functional areas, maintain DOE audit trails, and face DOE enforcement only.

Penalty exposure: Up to $121,876 per violation, assessed by DOE Office of Enterprise Assessments. No statute of limitations defense; DOE can assess violations for incidents years old. Willful or repeat violations may trigger contract fee adjustments or suspension.

Example: Hanford M&O contractor discovers a worker with beryllium exposure exceeding DOE action levels. Contractor reports to DOE; DOE launches investigation; finds contractor failed to implement required air monitoring per 10 CFR 851.23(b)(6). DOE issues enforcement letter; contractor has 30 days to respond. If root cause inadequate, FNOV + civil penalty follows. Cost: $100K–$300K+ if violation deemed willful.

Tier 2: Subcontractors of M&O Contractors (Primarily 10 CFR 851, with Exceptions)

Who: Specialized contractors (construction, maintenance, waste management, security) hired by M&O contractors

Sites: Same as Tier 1, but work assignment critical

What applies: Generally 10 CFR 851 if working at DOE-controlled parcels. If assigned to a privatized Project Parcel (post-April 17, 2026), 29 CFR + state plan applies for that parcel only.

Penalty exposure: Varies by assignment. If working under M&O contract control, DOE penalties apply. If at Project Parcel and discovered by OSHA/state plan, OSHA/state penalties apply.

Example: Subcontractor hired by Hanford M&O to repair a water line. If the water line is within the traditional DOE facility boundary, 10 CFR 851 applies. If the contractor is told “your work zone is on the solar farm parcel that’s leased to SunPower,” then DOSH (Washington) rules apply, and the subcontractor must verify compliance with Washington state standards, not DOE rules. Compliance gap: subcontractor trained only on 10 CFR 851; no one verified DOSH alignment.

Tier 3: Private Operators at Leased Parcels (29 CFR + State Plans, Post-April 17, 2026)

Who: Renewable energy companies, data center operators, light manufacturing, or other private entities

Sites: Project Parcels at INL (federal OSHA), Hanford (Washington DOSH), NNSS (Nevada plan), SRS (South Carolina plan)

What applies: 29 CFR + state-plan equivalents. No 10 CFR 851.

Penalty exposure: OSHA/state-plan penalties. 2025 willful violation: $11,823–$165,514. Serious violation: $16,550. Repeated violation: $165,514. State-plan states may have different caps or criteria.

Example: Sunrun installs a solar array on a leased parcel at Hanford. Workers fall under Washington DOSH, not DOE. DOSH conducts routine inspection; finds fall protection deficiency. DOSH issues citation for 29 CFR 1926.500 violation. Sunrun contests; case heard by Washington OSHRC. Settlement or hearing outcome. No DOE involvement.

Tier 4: Cleanup and Remediation Contractors (Dual Compliance, Complex)

Who: Environmental remediation contractors (e.g., DERA, WVNS, TRW Environmental Services) managing site cleanup

Sites: Historically contaminated DOE sites (Paducah, Portsmouth, other legacy facilities)

What applies: Often both. If contractor is under a DOE cleanup contract, 10 CFR 851 applies. But if the site has groundwater or soil contamination regulated under EPA RCRA or Superfund, state environmental agencies also oversee cleanup. Additionally, if the state is an OSHA state plan, OSHA state standards apply to workers. Result: 3-agency oversight (DOE + EPA + state OSHA).

Penalty exposure: Multiplied. Violation of 10 CFR 851 invokes DOE penalty ($121,876). Violation of state OSHA triggers state penalty (varies; often $10K–$50K). EPA environmental violation (RCRA non-compliance, e.g.) adds separate fine.

Example: Paducah site cleanup contractor encounters legacy uranium-contaminated soil. Contractor’s industrial hygiene monitoring detects worker exposure above DOE action level AND above OSHA PEL. DOE investigates contractor’s work practices; issues FNOV for 10 CFR 851 failure. Tennessee OSHA investigates same incident; issues citation for 29 CFR 1910.1000 (air contaminants) non-compliance. Contractor faces $121,876 (DOE) + $16,550 (Tennessee). Worse: contractor may not have understood that state OSHA had concurrent jurisdiction. Many cleanup contractors train exclusively on DOE rules and miss state-plan overlaps.

Enforcement Mechanics: How Violations Happen and What Follows

DOE 10 CFR 851 Enforcement

DOE’s Office of Enterprise Assessments conducts facility safety assessments (announced and unannounced) and investigates incidents, near-misses, and concerns submitted by workers, unions, or advocacy groups.

Timeline:

  1. Assessment or Investigation Launch. OEA notifies contractor that an assessment or investigation is underway. Contractor provides records (programs, hazard assessments, incident reports, training logs, industrial hygiene data). OEA inspectors tour facility, interview workers, review documentation.

  2. Enforcement Letter (EL) — Non-violative Finding. If OEA finds areas of concern but no regulatory violation, OEA issues an EL. This is “on the record” but not a violation. Contractors often treat EL as a soft warning to tighten procedures.

  3. Preliminary Notice of Violation (PNOV). If OEA determines a violation of 10 CFR 851 occurred, OEA issues a PNOV. Contractor has 30 days to respond: provide explanation, corrective actions, timeline for remediation. PNOV does not impose a penalty yet.

  4. Final Notice of Violation (FNOV) + Civil Penalty Determination. If OEA’s response to the PNOV shows the violation was substantive, or if the contractor’s corrective action is inadequate, OEA issues FNOV with a civil penalty. Penalty amount determined by severity (e.g., whether violation was willful, whether it created serious hazard, whether contractor has history of violations).

  5. Payment and Contract Action. Contractor pays penalty or contests via limited administrative process (not OSHRC-equivalent). Paid penalty may also trigger fee reduction in the DOE contract (M&O contracts often include safety performance clauses) or, in egregious cases, suspension of contract authority.

  6. No External Appeal. Unlike OSHA, DOE FNOV is not reviewable by an external independent board. The contractor’s recourse is internal DOE administrative review or, theoretically, federal court challenge (extremely rare and expensive).

Penalties (2026):

As of January 26, 2026, the maximum civil penalty per violation is $121,876, adjusted annually for inflation. DOE issued updated penalties effective December 27, 2024, reflecting 2025 adjustments. The 2026 adjustment will be published in late 2025 or early 2026, and is expected to be in the $123,000–$126,000 range based on recent inflation trends.

Contractors often face multiple citations in a single investigation. Example: one incident might yield citations for (1) failure to implement hazard assessment per 851.21(a), (2) failure to provide required PPE per 851.23(a)(3), (3) failure to document incident investigation per 851.24. Total: 3 × $121,876 = ~$365,628.

A single willful DOE violation thus carries more risk than an OSHA willful violation (max $165,514 for 2025), especially when multiplied across related findings.

OSHA 29 CFR Enforcement (Privatized Parcels + State Plans)

OSHA or state-plan agencies (federal or state) conduct complaint investigations, targeted inspections, follow-ups on hazard reports. Process is different from DOE.

Timeline:

  1. Inspection Trigger. OSHA/state plan receives complaint, schedules programmed inspection, or investigates incident report. Inspector arrives, may conduct walkaround interview, review records.

  2. Citation and Notice of Proposed Penalty (NOPP). If violations found, OSHA/state issues a citation specifying the violated standard, facts supporting the violation, and a proposed penalty amount. Employer has 15 working days to respond: pay penalty, contest citation, request conference with OSHA.

  3. Settlement or Contest. If employer pays, citation becomes final. If employer contests, case is docketed with the Occupational Safety and Health Review Commission (OSHRC, an independent board under Department of Labor). Pre-hearing conferences often lead to settlement agreements where penalty is reduced in exchange for admitting violation and agreeing to abatement.

  4. OSHRC Hearing or Settlement. If case proceeds to hearing, ALJ (Administrative Law Judge) hears evidence, takes testimony, issues decision. Either party may appeal ALJ decision to OSHRC commissioners (3-commissioner panel). Decisions may be appealed to federal appellate court, but are rarely overturned.

  5. Final Order. Once OSHRC order is final (no further appeal filed), employer must pay penalty and abate hazard by deadline specified.

2025 Penalties:

  • Serious violation: $16,550
  • Other-than-serious violation: $16,550
  • Willful violation: $11,823 (minimum) to $165,514 (maximum)
  • Repeated violation: $165,514 (maximum; must be same or substantially similar violation within 5 years)
  • Posting requirement violation: $16,550
  • Failure to abate (per day of continued violation after abatement deadline): $16,550

2026 Penalties: Not yet published. Expected January 2026. Likely ~$17,000–$18,000 range for serious/other-than-serious, $12,000–$170,000 for willful, based on ~2–3% annual inflation.

Comparative Penalty Analysis

Scenario 1: Single serious violation

  • DOE 10 CFR 851: $121,876 (no negotiation; flat rate unless adjusted for inflation)
  • OSHA 29 CFR: $16,550 (2025; likely $17,000+ in 2026); may be reduced by 50% or more if employer settles early in OSHRC process

Scenario 2: Willful violation (contractor knew of hazard, failed to abate)

  • DOE 10 CFR 851: $121,876 (DOE does not distinguish “willful” as a tier; all violations assessed by severity and history)
  • OSHA 29 CFR: $165,514 (maximum 2025; likely ~$170,000 in 2026); often settled at $75,000–$100,000 in OSHRC

Bottom line: DOE penalties are higher per violation and not negotiable. OSHA penalties can be negotiated and are subject to external review. However, OSHA investigations are more frequent in private-sector settings, so exposure is distributed across more inspections. DOE conducts fewer assessments but penalties, when issued, are severe.

iSi Cost Anchor Comparison: A single DOE 10 CFR 851 violation costs up to $121,876. An iSi Environmental industrial hygiene assessment—which catches hazards before DOE inspectors do—costs $4,050. The ROI is stark: spend $4,050 to avoid a $121,876 penalty. For federal contractors, this is a recurring calculus.

Which Standards Are Stricter? The Industrial Hygiene Example

This is where HSE directors often stumble: 10 CFR 851 is not a substitute for 29 CFR. It is additive. Contractors must meet both where applicable, and 10 CFR 851 often requires more.

Beryllium Exposure

29 CFR 1910.1024 (OSHA Beryllium Rule):

  • PEL (Permissible Exposure Limit): 0.2 µg/m³ (8-hour TWA)
  • Action level: 0.1 µg/m³
  • Employers must conduct monitoring if exposure reasonably expected

10 CFR 851 on Beryllium (§851.23(a)(3) & 851.24(a)):

  • Exempts OSHA’s beryllium standard except as provided in 10 CFR 850 (Chronic Beryllium Disease Prevention Program)
  • 10 CFR 850 is stricter: surrogate action level of 0.2 µg/m³ (same as OSHA PEL); medical surveillance triggered at lower thresholds; beryllium-specific medical monitoring; contractor must track exposures for life of worker

Contractor compliance gap: Contractor assumes OSHA beryllium limits apply; implements monitoring at 0.1 µg/m³ and stops. DOE assesses contractor, finds exposure data incomplete, worker medical files lacking long-term tracking. DOE issues violation for failure to comply with 10 CFR 850 medical surveillance. Contractor not cited by OSHA (no OSHA authority at DOE site), but DOE fine applies.

Ionizing Radiation

29 CFR 1910.1096 (OSHA Ionizing Radiation Rule):

  • 5,000 millirem per year (mrem/yr) annual limit
  • Regulatory authority applies to general industry with radiation sources

10 CFR 851 (DOE Sites with Radiation):

  • 100 mrem/yr average annual limit for occupational exposure
  • Most DOE contractors also comply with 10 CFR 20 (NRC equivalent) or DOE radiological orders, which set even tighter targets
  • 25 mrem/yr is the threshold for “privatized facility” jurisdiction in the April 2026 MOU

Contractor gap: Contractor assumes OSHA 5,000 mrem/yr limit; does not implement radiological controls. DOE assessment finds workers receiving 150–500 mrem/yr (far below OSHA PEL, compliant with general OSHA standard, but non-compliant with DOE’s tighter limit). DOE issues violation for radiological controls. Worker medical data examined; potential overexposure claim filed.

Industrial Hygiene Monitoring Scope

10 CFR 851.24 requires contractors to conduct “exposure assessments” across all nine functional areas, including occupational medicine and biological monitoring. This is broader than 29 CFR 1910.1020 (access to medical records), which requires medical records but not proactive biological monitoring unless specific standards (e.g., lead, beryllium) require it.

Contractor gap: Contractor implements OSHA-compliant air monitoring for volatile organics and noise. DOE assessment finds no biological monitoring program for workers handling chemical or radioactive materials. Even if air monitoring shows OSHA compliance, lack of biological data (urine biomarkers, blood levels) is a 10 CFR 851 violation. Contractor issues correction; DOE issues enforcement letter.

Takeaway: Do not assume OSHA compliance = 10 CFR 851 compliance. Contractors at DOE sites must implement 10 CFR 851 baseline plus OSHA standards, and reconcile conflicts by choosing the stricter limit.

The April 17, 2026 Addendum: What Actually Changed and What Didn’t

What Changed (Privatized Parcels)

Effective April 17, 2026, the following OSHA-DOE MOU addendum transferred regulatory authority from DOE to OSHA and state plans for specified Project Parcels:

Idaho National Laboratory (Pocatello, Idaho):

  • Project Parcels assigned to federal OSHA jurisdiction
  • Employers at these parcels must comply with 29 CFR (federal OSHA rules)
  • OSHA Area Office: Boise, ID
  • No DOE 10 CFR 851 oversight for these parcels

Hanford Site (Benton County, Washington):

  • Project Parcels assigned to Washington State Department of Labor & Industries (DOSH)
  • Employers at these parcels must comply with Washington Industrial Safety and Health Act (ISHA) and state-adopted standards
  • State standards typically track federal OSHA but may diverge; Washington DOSH enforces
  • Hanford M&O contractor (still DOE-regulated for DOE work) must differentiate: DOE work = 10 CFR 851; parcel work = Washington ISHA

Nevada National Security Site (Nye County, Nevada):

  • Project Parcels assigned to Nevada OSHA (state plan)
  • Employers must comply with Nevada OSHA standards
  • Nevada Division of Industrial Relations enforces

Savannah River Site (Aiken County, South Carolina):

  • Project Parcels assigned to South Carolina OSHA (state plan)
  • Employers must comply with South Carolina standards
  • Note: no announcement of specific SRS parcels yet; contractors should monitor Federal Register for details

What Did NOT Change (M&O Work Continues Under DOE)

All traditional DOE M&O contractors and subcontractors performing work on behalf of DOE at traditional facility boundaries remain under 10 CFR 851. Examples:

  • Hanford M&O contractor managing the site: 10 CFR 851
  • Subcontractors hired by Hanford M&O for site construction/maintenance: 10 CFR 851 (unless assigned to Project Parcel)
  • Oak Ridge National Laboratory: 10 CFR 851
  • Los Alamos National Laboratory: 10 CFR 851
  • Paducah and Portsmouth uranium enrichment plants: 10 CFR 851
  • Cleanup contractors at legacy sites: 10 CFR 851
  • Sandia and Lawrence Livermore: 10 CFR 851

The Critical Transition Gap

The April 2026 addendum does NOT specify how contractors should handle mixed-jurisdiction assignments (e.g., “I’m a subcontractor assigned to both DOE work and Project Parcel work”). HSE directors must:

  1. Confirm parcel boundaries with DOE. Get maps showing which areas are DOE-controlled vs. leased.
  2. Audit work assignments. For each task, determine: is this DOE work (10 CFR 851) or parcel work (OSHA/state plan)?
  3. Communicate with crews. Train crews differently based on assignment. Do not train all workers to 10 CFR 851 and assume OSHA compliance at parcels; standards differ (beryllium, radiation, industrial hygiene monitoring, program structure).
  4. Update contractor agreements. Require subcontractors to confirm jurisdiction before work starts.

Failure to clarify jurisdiction has led to mixed-compliance postures: contractors train to 10 CFR 851, work at privatized parcel under OSHA watch, inspector finds non-compliance with 29 CFR standard that 10 CFR 851 does not address (e.g., Washington state prevailing wage requirements, specific noise control methods). Citation issued; contractor argues “we followed DOE rules.” Not a defense to OSHA/state-plan citation.

State Plan States: A Deeper Dive

Contractors in state-plan states face a critical complexity: state-plan agencies enforce standards often stricter than federal OSHA, and the April 2026 addendum routes more DOE parcel work to state enforcement.

Washington State (Hanford)

Washington is a state-plan state covering private sector and public sector employees. Washington Industrial Safety and Health Act (ISHA) standards are frequently more stringent than federal OSHA.

Key differences:

  • Washington DOSH requires worker incident reporting for injuries causing 8+ hours of lost time (federal OSHA requires 24+ hours)
  • Washington prevailing wage standards apply to public works projects, including federal contractor work at Hanford (adds cost and compliance burden)
  • Washington has stricter fall protection standards for certain heights and configurations
  • Washington requires ergonomic assessment for all covered employers (federal OSHA has no general ergonomic rule)

Post-April 17, 2026 impact on Hanford contractors:

  • Subcontractors assigned to Project Parcels fall under DOSH, not DOE
  • M&O contractor must verify parcel status before dispatching crews
  • Training: crews at parcels must know Washington ISHA, not 10 CFR 851

iSi Service Fit: Federal contractors at Hanford with mixed DOE/DOSH assignments benefit from COOP retainer-based compliance monitoring. iSi can audit both jurisdictions, flag jurisdiction conflicts, and train crews accordingly.

Tennessee (Oak Ridge)

Tennessee Occupational Safety and Health (TOSHA) is a state-plan state, enforcing federal 29 CFR standards and some state-specific rules. Oak Ridge National Laboratory remains entirely DOE M&O (no privatized parcels per April 2026 addendum), so 10 CFR 851 applies to M&O and subcontractors.

But: cleanup contractors at nearby legacy sites (e.g., K-25 uranium enrichment facility, some decommissioned production areas) may face mixed jurisdiction if remediation work occurs at both DOE and non-DOE parcels. Tennessee OSHA may inspect; contractors must align.

Key difference: Tennessee has few state-specific enhancements beyond federal OSHA, so 29 CFR compliance largely equals TOSHA compliance. However, any contractor working at both DOE sites (10 CFR 851) and non-DOE sites in Tennessee (TOSHA) must maintain dual-compliance posture.

New Mexico (Los Alamos, Sandia)

New Mexico OSHA (NMOSHA) is state-plan. Los Alamos National Laboratory and Sandia National Laboratories remain DOE M&O sites; no privatized parcels announced per April 2026 addendum.

However: New Mexico has 22 DOE/contractor sites historically. The April 2026 addendum names only 4 sites; contractors should monitor Federal Register for future privatizations at Los Alamos, Sandia, or other New Mexico facilities.

New Mexico-specific issue: Environmental remediation contractors at Los Alamos often work under both DOE cleanup contracts (10 CFR 851) and EPA Superfund/RCRA oversight (environmental agency rules). Additionally, NMOSHA applies to worker safety. Result: three regulatory masters for one project, each with separate citations and penalties.

Upcoming Deadlines and Contractor Action Items

Immediate (April–June 2026):

  1. Confirm Parcel Status. HSE directors managing Hanford, INL, NNSS, or SRS operations should request updated facility maps and parcel designations from DOE. Determine which work falls under 10 CFR 851 vs. OSHA/state plan.

  2. Audit Subcontractor Jurisdiction. Review all active subcontracts. For each, confirm: is the work DOE-regulated (10 CFR 851) or at a privatized parcel (OSHA/state plan)? Notify subcontractors in writing of the jurisdiction that applies.

  3. Update Worker Safety Programs. If your site has both zones, update your Worker Safety and Health Program to distinguish requirements by zone. DOE Field Element Head must approve any material revisions.

  4. Retrain Supervisory Staff. Site safety managers, crew leads, and HSE coordinators need clarity on jurisdiction. Offer training: “Hanford April 2026 Addendum: What Changed for Your Site?”

  5. Coordinate with Privatized Operators. If your site has private-sector lessees (e.g., Sunrun solar at Hanford), coordinate boundary fencing, access controls, and safety messaging. Ensure your crews do not inadvertently enter parcel work zones unprepared.

Mid-Year (July–September 2026):

  1. Penalty Adjustments. Expect DOE and OSHA to publish 2026 penalty amounts in December 2025 or early January 2026. Once published, update your compliance cost models and audit budgets. 2026 penalties will likely be $123,000–$126,000 per DOE violation; $17,500–$175,000 per OSHA violation (depending on severity).

  2. Radiation Threshold Documentation. If your site has mixed radiation exposure, maintain records showing annual average exposure for workers. Parcels with <25 mrem/yr average are treated as privatized (OSHA jurisdiction); >25 mrem/yr remain DOE-regulated. Annual radiation monitoring reports should clearly state this threshold assessment.

  3. OSHA/State Plan Training. For crews potentially working at privatized parcels, conduct 29 CFR orientation training. Do not rely solely on 10 CFR 851 training; state-plan rules (especially Washington DOSH, Tennessee TOSHA, Nevada OSHA) differ.

Content Summary: What HSE Directors Must Know

The April 17, 2026 OSHA-DOE MOU Addendum Changed Jurisdiction—But Only for Privatized Parcels.

  • Four DOE sites now have Project Parcels under OSHA/state-plan authority (INL, Hanford, NNSS, SRS)
  • M&O contractors and DOE subcontractors remain under 10 CFR 851 for traditional facility work
  • The critical compliance gap: subcontractors working across both DOE and parcel zones must understand both regimes

10 CFR 851 Is Stricter Than 29 CFR on Most Industrial Hygiene Topics.

  • 10 CFR 851 mandates preapproval of programs, nine functional area implementation, stricter exposure limits (beryllium, radiation), and biological monitoring
  • OSHA’s 29 CFR is more flexible: prescribe standards, but employers design their own approaches
  • DOE penalties ($121,876 per violation) are higher than OSHA maximums ($165,514 willful); neither is negotiable with DOE but OSHA violations can be appealed/settled via OSHRC

Privatized Parcel Work Falls Under State-Plan Rules (Washington, Tennessee, Nevada, South Carolina).

  • State plans often exceed federal OSHA minimums (e.g., Washington DOSH prevailing wage, ergonomic assessment)
  • Mixed-jurisdiction contractors (DOE + state-plan work at one site) must differentiate training, procedures, and documentation by work zone

Contractors Must Act Now to Clarify Jurisdiction and Update Programs.

  • Request parcel maps from DOE
  • Audit subcontractor work assignments
  • Update Worker Safety and Health Programs for DOE approval (if dual-zone work applies)
