In a recent article, we reviewed the attendance requirements for loads of hazmat. That rule affects marked or placarded motor vehicles containing hazmat when on a public street, highway, or shoulder. But what exactly qualifies as a public street or highway? And why does it matter?

Knowing the meaning of public road helps you determine when Hazardous Material Regulations (HMR) apply to your operations – and when they don’t.

Definition of public roadway

Under 49 CFR 390.5, “highway” means any road, street, or way – whether on public or private property – that is open to public travel. “Open to public travel” means that the road section is:

  • Available, except during scheduled periods, extreme weather, or emergency conditions;
  • Passable by four-wheel standard passenger cars; and
  • Open to the general public for use without restrictive gates, prohibitive signs, or regulation (other than restrictions based on size, weight, or class of registration). Toll plazas of public toll roads are not considered restrictive gates.

An agency interpretation of that rule describes a public road as:

  • Any road under the jurisdiction of a public agency and open to public travel, or
  • Any road on private property that is open to public travel.

Scenario 1: Hazmat on company property

A truck carries hazmat between buildings of your corporate campus on private roads. When the entrance gates are open during business hours, there is public access to the facility. Corporate security officers patrol the campus and monitor the entrances with cameras.

The movement of hazmat that occurs entirely within a contiguous facility boundary where public access is restricted is not commercial transportation and therefore is not subject to the HMR. As such, it does not require a shipping paper, placards, or a Commercial Driver’s License with a hazmat endorsement. (Note that, even though drivers would not need a hazmat endorsement under the federal regulations, state or local authorities may require conformance with the requirement.)

Several agency Letters of Interpretation indicate that signs, signals, lights, gates, or guard stations are appropriate means of restricting public access.

Scenario 2: Stops while traveling

Your driver stops for lunch. Under 397.7(b), a motor vehicle that contains hazmat (other than Division 1.1, 1.2, or 1.3 materials) must not be parked on or within five feet of the traveled portion of public street or highway except for brief periods when the necessities of operation require the vehicle to be parked and make it impracticable to park the vehicle in any other place.

Parking a motor vehicle containing hazmat within five feet of traveled portion of highway or street is a “critical” violation. Understanding the definition of public roadway can help your drivers comply with this rule.

The bottom line

Remember, “highway” means any road, street, or way – whether on public or private property – that is open to public travel. This definition helps you decide how the hazmat rules apply to your operations, including, but not limited to:

  • Movements of hazmat on private roadways, where public access is restricted; and
  • Attendance requirements for loads on the road.

Key to remember: The meaning of “public road” helps to determine when Hazardous Material Regulations apply to your operations – and when they don’t.

EHS Monthly Round Up - April 2026

EHS Monthly Round Up - April 2026

In this April 2026 roundup video, we’ll review the most impactful environmental health and safety news.

Hi everyone! Welcome to the monthly news roundup video, where we’ll review the most impactful environmental health and safety news. Let’s take a look at what happened over the past month.

OSHA revised its National Emphasis Program on heat-related hazards. Going forward, the agency will prioritize inspections in 55 high-risk industries in indoor and outdoor work settings. The program remains in effect for 5 years from its April 10 effective date.

An OSHA proposed rule seeks to eliminate the November 18, 2036, deadline in the Walking-Working Surfaces standard that would require all fixed ladders extending more than 24 feet above a lower level to be equipped with personal fall arrest systems or ladder safety systems. OSHA also seeks feedback on nine specific questions related to the proposal, with comments due on June 5.

On April 17, OSHA revoked its House Falls in Marine Terminals standard at 1917.41. The agency said that because most cargo has been containerized and is moved by cranes, the standard is no longer necessary to protect employees.

Turning to environmental news, an EPA final rule further delays the submission period for the one-time PFAS report required of manufacturers. It pushes the start of the submission period to either 60 days after the effective date of a future final rule updating the PFAS Reporting Rule or January 31, 2027, whichever comes first.

An EPA final rule makes technical changes to the emission standards established in March 2024 for crude oil and natural gas facilities. The changes take effect June 8.

EPA published the draft 6th Contaminant Candidate List for the next group of contaminants to be considered for regulation under the Safe Drinking Water Act. The proposed list designates microplastics and pharmaceuticals as priority contaminant groups for the first time.

And finally, EPA plans to make significant changes to coal combustion residuals requirements. A proposed rule published April 13 would revise the regulations governing the disposal of coal combustion residuals in landfills and surface impoundments, as well as the beneficial use of coal combustion residuals.

Thanks for tuning in to the monthly news roundup. We’ll see you next month!

EHS Monthly Round Up - February 2026

EHS Monthly Round Up - February 2026

In this Februrary 2026 roundup video, we'll discuss the most impactful environmental health and safety news.

Hi everyone! Welcome to the monthly news roundup video, where we’ll review the most impactful environmental health and safety news. Let’s take a look at what happened over the past month.

Fatal work injuries fell 4 percent in 2024, largely due to a decline in workplace drug- and alcohol-related overdoses. According to the Bureau of Labor Statistics, overdose fatalities fell from 512 in 2023 to 410 in 2024. Across all types of workplace incidents, there were 5,070 fatal work injuries in 2024, compared to 5,283 in 2023. Transportation incidents continue to be the most frequent type of fatal event, accounting for over 38 percent of all occupational fatalities in 2024.

OSHA is fast-tracking a proposal to remove the 2036 obligation to upgrade fall protection systems on fixed ladders that extend over 24 feet. This follows an industry petition from major chemical and petroleum industry groups, which argue the provision is unjustified, costly, and not supported by the rulemaking record. OSHA frames the upcoming proposed action as deregulatory, allowing employers to update fixed ladders at the end of their service lives. We’ll provide updates as more information becomes available.

As OSHA leans into “deregulatory” actions, lawmakers are moving to pressure the agency to issue “regulatory” rulemaking to protect American workers. The latest legislative wave of bills aims to fill regulatory gaps, tackle emerging hazards, expand OSHA authority, and raise penalties. Topics addressed by these bills include musculoskeletal disorders, heat stress, infectious diseases, wildfire smoke, and workplace violence.

In a recently issued letter of interpretation, OSHA states that a burn injury caused by a personal lithium-ion battery fire is work related if it occurs in the workplace during assigned working hours. The letter details an incident where an employee was burned when their rechargeable lithium-ion batteries for e-cigarettes sparked a fire after coming into contact with a key used for work.

A new report from the Department of Labor Office of Inspector General concludes that OSHA struggles to meet its mission, particularly in high-risk industries like healthcare, construction, and manufacturing. Several pages point to OSHA’s difficulties in effectively enforcing annual injury and illness reporting requirements, reaching the nation’s high-risk worksites for inspection, and addressing workplace violence by regulatory or other action.

Turning to environmental news, EPA extended the deadlines for Facility Evaluation Reports and related requirements for coal combustion residuals facilities. In most instances, the deadlines have been moved one or two years out.

And finally, EPA announced a final rule eliminating the 2009 Endangerment Finding and related greenhouse gas emission requirements for on-highway vehicles and vehicle engines. When the final rule takes effect, manufacturers and importers of new motor vehicles and motor vehicle engines will no longer have to measure, report, certify, or comply with federal greenhouse gas emission standards.

EHS Monthly Round Up - March 2026

EHS Monthly Round Up - March 2026

In this March 2026 roundup video, we'll review the most impactful environmental health and safety news.

Hi everyone! Welcome to the monthly news roundup video, where we’ll review the most impactful environmental health and safety news. Let’s take a look at what happened over the past month.

OSHA released an updated Job Safety and Health poster. Employers can use either the revised version or the older one, but the poster must be displayed in a conspicuous place where workers can easily see it.

OSHA recently removed a link from its Data topic webpage that displayed a list of “high-penalty cases” at or over $40,000 since 2015. The agency says it discontinued and removed it in December. The data is frozen and archived elsewhere.

OSHA published two new resources as part of its newly launched Safety Champions Program. The fact sheet provides an overview of how the program works, eligibility criteria, and key benefits. The step-by-step guide helps businesses navigate the core elements of OSHA’s Recommended Practices for Safety and Health Programs.

Several forces are nudging OSHA to address a number of workplace hazards and high-hazard industries. This comes from other agencies, safety organizations, watchdogs, legislative proposals, and persistent injury/fatality data. Among the hazards are combustible dust; first aid; personal protective equipment; and workplace violence. How all this translates into new regulations, guidance, programmed inspections, or other initiatives remains to be seen.

Turning to environmental news, EPA issued a proposed rule to require waste handlers to use electronic manifests to track all RCRA hazardous waste shipments. Stakeholders have until May 4 to comment on the proposal.

On March 10, EPA finalized stronger emission limits for new and existing large municipal waste combustors and made other changes to related standards.

And finally, EPA temporarily extended coverage under the 2021 Multi-Sector General Permit for industrial stormwater discharges until the agency issues a new general permit. The permit expired February 28 and remains in effect for facilities previously covered. EPA won’t take enforcement action against new facilities for unpermitted stormwater discharges if the facilities meet specific conditions.

EHS Monthly Round Up - January 2026

EHS Monthly Round Up - January 2026

In this January 2026 roundup video, we'll review the most impactful environmental health and safety news.

Hi everyone! Welcome to the monthly news roundup video, where we’ll review the most impactful environmental health and safety news. Let’s take a look at what happened over the past month.

Chemical manufacturers, importers, distributors, and employers will have an extra four months to comply with the provisions of OSHA’s revised Hazard Communication standard. When the rule was revised in 2024, it contained staggered compliance dates for those who classify or use chemical substances and mixtures. The first compliance date is now May 19 rather than January 19 of 2026.

On January 8, OSHA issued further technical corrections to its Hazard Communication final rule. An initial set of corrections was published in October 2024, and OSHA continued to review the standard for errors. The agency said these corrections should reduce confusion during the chemical classification process and prevent errors on labels and safety data sheets.

In 2024, private industry employers reported 2.5 million nonfatal workplace injuries and illnesses, according to the Bureau of Labor Statistics. This is down 3.1 percent from 2023 and largely due to a decrease in respiratory illnesses. The greatest number of cases involving days away from work, job restriction, or transfer were caused by overexertion, repetitive motion, and bodily conditions, followed by contact incidents.

Registration is open for OSHA’s Safety Champions Program, which is designed to help employers develop and implement effective safety and health programs. Participants can work at their own pace through Introductory, Intermediate, and Advanced levels.

Turning to environmental news, on January 9, EPA withdrew its direct final rule on SDS/Tier II reporting tied to OSHA HazCom, before it had a chance to take effect. The direct final rule was published back on November 17, 2025, and was intended to relax the Tier II and safety data sheet reporting requirements and align with OSHA’s HazCom standard. EPA said it plans to write a new rule addressing all public comments.

And finally, EPA published a final rule that changes certain requirements for wastewater discharges from coal-fired steam electric power plants. It applies to the deadlines established by the preceding rule finalized in 2024.

EPA postpones compliance for TCE uses with TSCA Section 6(g) exemptions
2026-05-07T05:00:00Z

EPA postpones compliance for TCE uses with TSCA Section 6(g) exemptions

On May 5, 2026, the Environmental Protection Agency (EPA) published a final rule postponing the effective date of compliance requirements for trichloroethylene (TCE) uses with Toxic Substances Control Act (TSCA) Section 6(g) exemptions until pending judicial review is concluded.

Who’s impacted?

The delay applies to the conditions imposed on each TSCA Section 6(g) exemption at 40 CFR 751.325, including the Workplace Chemical Protection Program requirements at 751.315.

Since the compliance requirements haven’t taken effect, facilities that use TCE with TSCA Section 6(g) exemptions don’t have to comply with the provisions yet.

Why the delay?

In December 2024, EPA released the final TCE rule (2024 TCE rule). The rule ultimately bans all uses of TCE, but it allows uses with TSCA Section 6(g) exemptions to continue for a limited time as long as facilities comply with strict workplace controls. Currently, the 2024 TCE rule is under judicial review. EPA has delayed the effective date of the requirements for TCE uses with TSCA Section 6(g) exemptions until the judicial challenges to the 2024 TCE rule are resolved.

If you have a sense of déjà vu, it’s for a good reason. This is the fifth time the agency has delayed the compliance requirements for TSCA Section 6(g) exemptions. However, EPA’s previous postponements established specific dates for the provisions to take effect, but this rule doesn’t.

Key to remember: EPA has delayed the compliance requirements for TCE uses with TSCA Section 6(g) exemptions until pending judicial review is concluded.

Wisconsin adds requirements to federal lead and copper drinking water rule

Effective date: May 1, 2026

This applies to: Public water systems

Description of change: The Wisconsin Department of Natural Resources (department) finalized amendments to align state regulations with the Environmental Protection Agency’s (EPA’s) updated lead and copper control requirements for drinking water. While most of the amendments conform to federal standards, the state has additional standards. The department also:

  • Requires community water systems to make four contact attempts (two more than federal requirements) by two different means for elementary schools and childcare facilities to schedule lead monitoring,
  • Requires public water systems on reduced annual monitoring to analyze and report the same number of sample results for copper and lead (instead of the federal requirements that only half of the copper samples are analyzed),
  • Requires public water systems undergoing temporary treatment or source water changes (unregulated by EPA) for more than 30 days to notify the department 10 days before the planned change or as soon as possible for an unplanned emergency change,
  • Requires groundwater system water suppliers that request to limit their entry point sampling to obtain prior approval from the department,
  • Requires water suppliers that provide point-of-use treatment devices for the corrosion control treatment compliance flexibility option to submit a written plan to the department (not required by the federal rule),
  • Grants the department the authority to require analysis of total and dissolved lead during distribution system and site assessments where the federal rule doesn’t provide this authority to the state,
  • Requires water suppliers that request to invalidate a reported sample result to provide substantial evidence that the sample meets one of the invalidation criteria in the rule, and
  • Combines the lead and copper monitoring waivers into one waiver and requires public water systems to complete at least two 6-month rounds of standard tap water monitoring (for which the federal rule only requires one 6-month round).

  • Heavy-Duty Engine and Vehicle Omnibus Low NOx (Omnibus).

CARB allows manufacturers to comply with ACC II and Omnibus requirements voluntarily.

In 2025, the Environmental Protection Agency revoked CARB’s waivers to implement the ACC II, Omnibus, and Advanced Clean Trucks rules.

Hazardous waste manifests: Hybrid vs. fully electronic
2026-04-28T05:00:00Z

Hazardous waste manifests: Hybrid vs. fully electronic

More industries are embracing the exclusive use of electronic platforms. For example, digital payments are replacing cash, news sites are going fully online, and cloud storage is eclipsing external computer storage. And, based on recent proposed rulemaking, hazardous waste manifests may join the list.

The Environmental Protection Agency (EPA) proposed the Paper Manifest Sunset Rule in March 2026, planning to shift to electronic-only manifests for tracking hazardous waste that’s regulated by the Resource Conservation and Recovery Act (RCRA).

If the proposed rule is finalized, regulated entities will have to track all hazardous waste shipments electronically. Specifically, generators, transporters, and receiving facilities could only use hybrid or fully electronic manifests on the Hazardous Waste Electronic Manifest System (e-Manifest).

So, what are the differences between hybrid and fully electronic manifests? Let’s compare the distinctions and explore some of the benefits that electronic manifests can offer.

What’s a hybrid manifest?

EPA initially established the hybrid manifest for generators that couldn’t fully participate in electronic manifests when the e-Manifest launched in 2018. The hybrid manifest combines paper and electronic manifests, allowing generators that aren’t registered in e-Manifest or don’t have an EPA identification (ID) number to sign printed copies of electronic manifests.

Here’s the general hybrid manifest process:

  • The first transporter initiates an electronic manifest in e-Manifest. A hard copy of the electronic manifest is printed out, and the generator and initial transporter sign the paper copy.
  • The generator keeps a signed paper copy on-site. The transporter keeps a signed paper copy with the shipment until it’s delivered to the receiving facility.
  • From that point forward, the initial transporter and all subsequent waste handlers track the shipment in e-Manifest (using electronic signatures and electronic transmissions).
  • The manifest is complete when the receiving facility or exporter electronically signs it on e-Manifest.

What’s a fully electronic manifest?

The fully electronic manifest is tracked completely online. All handlers — generators, transporters, and receiving facilities or exporters — must have an EPA ID number and be registered in e-Manifest to use the fully electronic manifest.

The entire process is conducted on e-Manifest:

  • The manifest is created electronically in e-Manifest.
  • All handlers electronically sign the manifest in e-Manifest.
  • The manifest is complete when the receiving facility or exporter electronically signs it on e-Manifest.

What benefits do electronic manifests offer?

Regardless of whether EPA’s rule is finalized as is, electronic manifests offer hazardous waste handlers a range of benefits. Consider the following potential perks.

Compliance with existing regulations

Many handlers are already required to embrace electronic manifesting. In July 2024, EPA finalized the e-Manifest Third Rule, which requires:

  • Large quantity generators and small quantity generators to register for e-Manifest,
  • Exporters to submit manifests and continuation sheets to e-Manifest (and pay the associated fees), and
  • Waste handlers to submit manifest-related reports and data corrections to e-Manifest.

Streamlined recordkeeping for generators

Hazardous waste handlers using e-Manifest automatically meet the recordkeeping requirements to maintain records of manifests (paper or electronic) since the manifests are retained electronically in the system.

This eliminates the need to keep hard copies. It also provides a centralized place where handlers can access these documents at any time.

However, the provision doesn’t apply to generators using hybrid manifests; they must keep the initial paper copies of the electronic manifest for 3 years.

Reduced costs

Embracing electronic manifesting removes the costs associated with printing paper manifests from EPA-approved sources.

Keep in mind, there’s an unavoidable cost for receiving facilities and exporters. These entities have to pay user fees for each manifest they submit to e-Manifest.

Proactive preparation

EPA’s proposed Paper Manifest Sunset Rule would prohibit the use of paper manifests 2 years after the publication of a final rule. Hazardous waste handlers who transition to using only electronic manifests now will be better prepared to comply with future regulations. It gives businesses time to coordinate resources and address any unexpected issues.

Key to remember: Do you know the differences between hybrid and fully electronic hazardous waste manifests? The distinctions could be the difference between compliance and noncompliance.

EPA publishes first round of expiring TSCA CBI claims
2026-04-27T05:00:00Z

EPA publishes first round of expiring TSCA CBI claims

The Environmental Protection Agency (EPA) published the first list of expiring Confidential Business Information (CBI) claims for information submitted under the Toxic Substances Control Act (TSCA). The list covers CBI claims that expire from June 22, 2026, to July 31, 2026.

What are expiring CBI claims?

The Frank R. Lautenberg Chemical Safety for the 21st Century Act (which became law in June 2016) set an automatic 10-year expiration for most CBI claims made under TSCA. The first round of expiring claims starts in June 2026.

EPA allows businesses to request extensions of CBI protection for up to another 10 years.

How do I know if my CBI claims are expiring?

EPA will notify businesses of expiring CBI claims directly through the Central Data Exchange (CDX).

The agency will also release public lists of upcoming expiring CBI claims monthly on the “CBI Claim Expiration” webpage. The agency encourages businesses to review the lists to verify whether any of their claims are included.

How do I request an extension of expiring CBI claims?

Businesses seeking to extend a CBI claim beyond its expiration date must submit an extension request at least 30 days before the claim expires using the newly launched TSCA Section 14(e) CBI Claim Extension Request application in EPA’s CDX.

Here’s the general process:

  • EPA notifies the business of an expiring CBI claim directly through CDX and via the public lists on the “CBI Claim Expiration” webpage.
  • The business submits a request for extension through EPA’s CDX at least 30 days before the CBI claim expires. Requests must comply with the substantiation requirements at 40 CFR 703.5(a) and (b).
  • EPA reviews the submission and either grants or denies the request.

What are the possible results?

If EPA approves the extension request, the information in the CBI claim will remain protected for up to another 10 years.

If EPA denies the extension request, the agency can publicize the information in the claim 30 days after notifying the submitter in CDX. Further, if a business doesn’t submit an extension request at least 30 days before the expiration date, EPA may publicize the information without notifying the submitter.

Key to remember: EPA published the first round of expiring CBI claims for information submitted under TSCA. Businesses must submit extension requests to keep the information protected.

California permanently adopts EPA’s conditional exemption for airbag waste

Effective date: March 6, 2026

This applies to: Airbag waste handlers and transporters

Description of change: The California Department of Toxic Substances Control permanently adopted the Environmental Protection Agency’s (EPA’s) interim final rule that allows airbag waste handlers and transporters to meet less stringent hazardous waste requirements (e.g., not manifesting the waste) if they meet certain conditions. Once the airbag waste is received at a collection facility or designated facility for proper disposal, it must be managed as hazardous waste.

The scope of the rule applies to all airbag waste, including recalled airbag inflators.
