OSHA's HAZWOPER Numbers Just Dropped 36.7% — What That Says About Your Disposal Pipeline

OSHA Just Confirmed in Federal Data That Your RCRA Disposal Universe Is Contracting

If you run hazardous waste operations at a permitted TSDF, ship Subtitle C waste from a manufacturing facility, or coordinate HAZWOPER training for emergency responders, the May 8, 2026 Federal Register notice is worth reading in detail. OSHA published the renewed Information Collection Request for the HAZWOPER Standard at 29 CFR 1910.120 (OMB Control No. 1218-0202, FR Doc. 2026-09119, 91 FR 25386). The headline most readers will see is that the comment period closes July 7, 2026.

The headline most readers should see is buried in Section III of the notice. OSHA estimates 17,211 respondents for this ICR cycle. The 2023 cycle estimated 27,186 respondents. That is a drop of 9,975 organizations — roughly 36.7% — in three years. OSHA gives a one-sentence cause:

“The adjustment decrease is primarily due to a decline in the number of Resource Conservation & Recovery Act (RCRA) treatment, storage, and disposal (TSD) cleanup sites.” (91 FR 25387)

Your training obligations under 1910.120 did not change. Your written safety and health program did not change. Medical surveillance, decontamination, and recordkeeping rules are unchanged. What changed is the count of sites that trigger those obligations — and OSHA is the one telling you so. For generators that depend on TSDFs for disposal, that is a market-structure signal you have to read alongside the regulatory text.

This post unpacks what the renewed ICR confirms, what it doesn’t, and how a smart EHS director or HAZWOPER coordinator should respond before July 7, 2026.

What Didn’t Change in the May 2026 HAZWOPER ICR

The substantive HAZWOPER standard at 29 CFR 1910.120 — and its identical construction analog at 29 CFR 1926.65 — is unchanged by the ICR renewal. The ICR only restates how OSHA estimates the paperwork burden of the existing rule. The rule itself stays in force as written.

For workers on uncontrolled hazardous waste sites, the training tier structure at 1910.120(e) is intact:

40-hour initial training plus three days of supervised field experience for general site workers — laborers, equipment operators, and on-site supervisors
24-hour initial training plus one day of supervised field experience for “occasional site workers” exposed below permissible exposure limits and below published health-hazard levels
8-hour annual refresher training for every previously certified worker
Additional 8 hours of supervisory training for on-site managers

For RCRA-permitted TSDFs, the additional provisions at 1910.120(p) — hazard communication, decontamination procedures, new-employee training, drum and container handling — apply alongside the 40 CFR 264.16 personnel training requirements that your Part B permit references.

For emergency responders, the five-tier structure at 1910.120(q) — Awareness, Operations, Technician, Specialist, Incident Commander — and the annual training and drill obligations are unchanged.

What the ICR did change is the agency’s quantitative estimate of who is doing this work. The agency now reports an adjustment decrease of 18,334 burden hours (from 251,002 to 232,668) and an adjustment decrease of $364,121 in operation and maintenance costs (from $3,769,483 to $3,405,362). These are not regulatory rollbacks. These are OSHA’s own data points on a contracting regulated population.

How Should an EHS Director Read a 36.7% Respondent Drop?

The number is not random. OSHA cites the decline in RCRA TSD cleanup sites as the primary driver. That observation matters for two distinct reader populations:

If you operate a permitted TSDF, the federal signal is consistent with what you already see in the field: capacity consolidation. Per EPA, the agency and its state partners maintain oversight of approximately 6,600 facilities and 20,000 hazardous waste units nationwide. The OSHA ICR data captures only HAZWOPER-trigger employers, but the directional signal aligns with industry data: Clean Harbors reported 92% incinerator utilization in Q3 2025, up from 89% the prior year, with PFAS-related volumes contributing 20–25% quarter-over-quarter growth. EPA’s own January 2025 National Capacity Assessment Report addressed capacity strain explicitly. Translation: fewer cleanup sites driving HAZWOPER-trigger work, but tighter throughput at the receiving facilities that still operate.

If you operate as a RCRA generator (LQG, SQG, or VSQG) shipping waste off-site for treatment or disposal, the same data points to two compounding effects:

The pool of available TSDFs in your region may be narrowing, while the survivors are running closer to capacity.
The HAZWOPER-trained contractor base for spill response, emergency cleanup, and corrective-action support is also thinning. With 9,975 fewer respondent organizations in the 2026 ICR, mutual-aid arrangements and pre-contracted spill responders should be re-verified — the contractor you used in 2023 may no longer be operating, or may have been acquired.

This is not alarmism. This is OSHA’s published data plus active industry capacity signals telling you the disposal pipeline you depend on is consolidating.

What Does Stacked OSHA + EPA Penalty Exposure Actually Look Like at a TSDF?

For TSDF operators, this is the area where a contracting market raises practical compliance risk most acutely. A facility under capacity pressure is more likely to push throughput. A facility pushing throughput is more likely to under-document training, defer medical surveillance, or let a written health and safety plan go stale. Both OSHA and EPA write penalties for those gaps, and the penalties stack.

OSHA penalty levels (effective January 15, 2025; held flat for 2026 by OMB Memo M-26-11):

Serious violation: $16,550 (29 CFR 1903.15)
Willful or repeated violation: $165,514 (29 CFR 1903.15)
Failure to abate: $16,550 per day

OSHA applies citations on an instance-by-instance basis for training violations. Five untrained employees on a cleanup crew is five Serious citations, not one. Cited willfully, that is $827,570 before any other count.

EPA RCRA penalty exposure runs in parallel under RCRA Section 3008, inflation-adjusted at 40 CFR 19.4:

§3008(a)(3) general violation: $93,058 per day per violation
§3008(c) failure to comply with a compliance order: $124,426 per day per violation
§3008(g) failure to comply with permit conditions: $93,058 per day per violation

The stack is real. If a TSDF training failure under 1910.120 also constitutes a violation of the personnel training requirements at 40 CFR 264.16 incorporated into the facility’s Part B permit, OSHA can cite under the OSH Act and EPA (or the authorized state agency) can issue a Notice of Violation under RCRA §3008 simultaneously. A multi-day failure to abate against multiple employees can reach seven figures before the case ever sees a hearing.

A single industrial hygiene assessment that catches a training documentation gap before the OSHA inspector does costs $4,050. A single willful 1910.120 citation costs $165,514. That is a 41:1 return on a phone call — and it does not count the parallel RCRA exposure that would have stacked on top.

What Should TSDF Operators and Generators Do Before July 7, 2026?

The 60-day comment period on the renewed ICR is not the operational deadline most facilities should care about. Trade associations and large multi-site employers may comment on burden estimates. For most TSDFs and generators, the practical work is internal.

1. Re-Inventory Your HAZWOPER-Trained Personnel

Every employee performing 1910.120-covered work needs documented initial training (40-hour, 24-hour, or appropriate 1910.120(q) tier) plus current annual 8-hour refresher. With cleanup-site contractor contraction, in-house bench depth matters more than it did three years ago. A facility that previously relied on a contracted spill responder should not assume that responder is still available — the 36.7% respondent drop in the OSHA ICR includes contracted responders.

Audit:

Initial training certificates for every covered employee (date, hours, training provider)
Current 8-hour annual refresher dates — anyone past 12 months from prior refresher is out of compliance
Three days of supervised field experience documentation for 40-hour graduates
Five-tier emergency response training documentation per 1910.120(q)(6)

2. Re-Verify Your Off-Site Disposal Vendor Pipeline

If the federal data signals fewer TSDFs and tighter throughput, generators should not assume their 2023 disposal contracts hold. Confirm:

Active permits for each TSDF you ship to (RCRAInfo lookup)
Tipping-fee schedules for 2026 — capacity tightness usually translates to price increases
Backup TSDF options if your primary receiving facility hits capacity or closes
Manifest-to-receipt cycle times — extended receiving queues can affect your 90-day generator accumulation timeline at LQGs

3. Confirm Your State’s Position

RCRA Subtitle C is administered through state-authorized programs in 44 states plus Guam under 40 CFR Part 271. Several state programs are more stringent than the federal floor:

Missouri (MDNR) — Updated state hazardous waste rules incorporating substantial RCRA federal updates effective July 1, 2024
Kansas (KDHE) — Authorized program; in process of adopting recent federal RCRA updates
Texas (TCEQ) — 30 TAC Chapter 335 with multiple more-stringent provisions
Oklahoma (DEQ) — Authorized program with state-specific generator and TSDF provisions
Nebraska (NDEE) — Authorized program

Twenty-two states plus Puerto Rico also operate OSHA-approved State Plans for private-sector worker protection. If you operate in Kentucky, North Carolina, South Carolina, or Virginia, your 1910.120 enforcement runs through the state plan agency, not federal OSHA. State plan agencies can adopt their own enforcement priorities and penalty schedules at or above the federal baseline.

4. Pair This Notice With the Companion EPA Action

The May 8, 2026 OSHA HAZWOPER ICR did not arrive in isolation. The same week, EPA published the withdrawal of the proposed RCRA corrective action SWMU definitional expansion (FR Doc. 2026-09179). Both actions point in the same direction: the federal pipeline of new RCRA cleanup work is narrowing, the regulated universe is contracting, and the substantive obligations on existing permit holders are unchanged.

For TSDF operators, that means the corrective action universe at your facility is anchored to your existing Part B permit and existing administrative orders — not to a prospective expansion. For generators, it means the regional cleanup-contractor base is thinner and the disposal market is consolidating. Read the two notices together when you brief your leadership team.

5. Document the ICR Decrease in Your Internal Compliance Files

For any in-flight permit renewal, audit, or M&A due diligence, the OSHA HAZWOPER ICR is now the federal record on the regulated population. If your organization maintains internal compliance assumptions about HAZWOPER respondent counts, training-vendor capacity, or contracted responder availability, update those assumptions to reflect the May 2026 data. Future positioning should be anchored to the published numbers, not to 2023 baselines.

Why the ICR Decrease Is Useful Information Even If You Are Not Commenting

Most facilities will not file a comment by July 7, 2026 — and that is fine. The ICR comment process is primarily for trade associations and multi-site employers that want to push back on burden-hour methodology. The reason every covered employer should still pay attention:

OSHA’s 17,211-respondent estimate becomes the federal baseline for the next three-year cycle. State-plan agencies, EPA regions, and other federal regulators reference these numbers when they brief their own leadership on enforcement priorities. The data is now part of the public record on the contracting RCRA cleanup-site universe. Reading it tells you what the regulators are reading.

For an EHS director or HAZWOPER coordinator briefing a CFO or plant manager: “OSHA’s own data shows the regulated population for HAZWOPER is down 36.7% since 2023, attributed to fewer RCRA TSD cleanup sites. Our training obligations are unchanged, but our disposal vendor pipeline and contracted responder availability are exposed to that contraction. Here is our internal verification of both.”

That is a stronger framing than “we need to keep training up to date.” It is grounded in published federal data, it explains why disposal costs may rise, and it justifies the time spent re-verifying contractor availability before you find out the hard way.

Get Help Auditing Your HAZWOPER Program and RCRA Disposal Pipeline

iSi Environmental works with TSDF operators, RCRA generators, and HAZWOPER-regulated employers across Kansas, Missouri, Oklahoma, Texas, Nebraska, Arkansas, and the broader 40-state iSi service area. If your facility falls into one of the categories above and you have not run a documentation audit against the renewed ICR baseline, an iSi industrial hygiene and compliance assessment will surface the gaps before an inspector does.

A full-time environmental hire to manage HAZWOPER, RCRA, and emergency response coordination internally runs $130,000–$195,000 fully loaded — salary, benefits, training, PTO, office space, recruiting cost. iSi’s COOP retainer puts a national team across 40 states behind your existing safety manager for $15,000–$90,000 per year. That is 10–70% of the cost of a full-time hire, with no headcount commitment, no recruiting cycle, and no single-point-of-failure risk if your hire leaves and walks out with your compliance history.

For TSDFs and generators navigating a contracting disposal market, the RCRA compliance audit and EHS COOP integration are the two services most directly relevant to the May 2026 ICR signal. A 30-minute conversation with our team will tell you whether your existing program holds up against the renewed federal baseline.
