Appendix A to Part 391—Medical Advisory Criteria

I. Introduction

This appendix contains the Agency’s guidelines in the form of Medical Advisory Criteria to help medical examiners assess a driver’s physical qualification. These guidelines are strictly advisory and were established after consultation with physicians, States, and industry representatives, and, in some areas, after consideration of recommendations from the Federal Motor Carrier Safety Administration’s Medical Review Board and Medical Expert Panels.

II. Interpretation of Medical Standards

Since the issuance of the regulations for physical qualifications of commercial motor vehicle drivers, the Federal Motor Carrier Safety Administration has published recommendations called Advisory Criteria to help medical examiners in determining whether a driver meets the physical qualifications for commercial driving. These recommendations have been condensed to provide information to medical examiners that is directly relevant to the physical examination and is not already included in the Medical Examination Report Form.

A. Loss of Limb: §391.41(b)(1)

A person is physically qualified to drive a commercial motor vehicle if that person: Has no loss of a foot, leg, hand or an arm, or has been granted a Skills Performance Evaluation certificate pursuant to §391.49.

B. Limb Impairment: §391.41(b)(2)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no impairment of:

(i) A hand or finger which interferes with prehension or power grasping; or

(ii) An arm, foot, or leg which interferes with the ability to perform normal tasks associated with operating a commercial motor vehicle; or

(iii) Any other significant limb defect or limitation which interferes with the ability to perform normal tasks associated with operating a commercial motor vehicle; or

(iv) Has been granted a Skills Performance Evaluation certificate pursuant to §391.49.

2. A person who suffers loss of a foot, leg, hand or arm or whose limb impairment in any way interferes with the safe performance of normal tasks associated with operating a commercial motor vehicle is subject to the Skills Performance Evaluation Certificate Program pursuant to §391.49, assuming the person is otherwise qualified.

3. With the advancement of technology, medical aids and equipment modifications have been developed to compensate for certain disabilities. The Skills Performance Evaluation Certificate Program (formerly the Limb Waiver Program) was designed to allow persons with the loss of a foot or limb or with functional impairment to qualify under the Federal Motor Carrier Safety Regulations by use of prosthetic devices or equipment modifications which enable them to safely operate a commercial motor vehicle. Since there are no medical aids equivalent to the original body or limb, certain risks are still present, and thus restrictions may be included on individual Skills Performance Evaluation certificates when a State Director for the Federal Motor Carrier Safety Administration determines they are necessary to be consistent with safety and public interest.

4. If the driver is found otherwise medically qualified (§391.41(b)(3) through (13)), the medical examiner must check on the Medical Examiner’s Certificate that the driver is qualified only if accompanied by a Skills Performance Evaluation certificate. The driver and the employing motor carrier are subject to appropriate penalty if the driver operates a motor vehicle in interstate or foreign commerce without a current Skill Performance Evaluation certificate for his/her physical disability.

C. [Reserved]

D. Cardiovascular Condition: §391.41(b)(4)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no current clinical diagnosis of myocardial infarction, angina pectoris, coronary insufficiency, thrombosis or any other cardiovascular disease of a variety known to be accompanied by syncope, dyspnea, collapse or congestive cardiac failure.

2. The term “has no current clinical diagnosis of” is specifically designed to encompass: “a clinical diagnosis of” a current cardiovascular condition, or a cardiovascular condition which has not fully stabilized regardless of the time limit. The term “known to be accompanied by” is designed to include a clinical diagnosis of a cardiovascular disease which is accompanied by symptoms of syncope, dyspnea, collapse or congestive cardiac failure; and/or which is s likely to cause syncope, dyspnea, collapse or congestive cardiac failure.

3. It is the intent of the Federal Motor Carrier Safety Regulations to render unqualified, a driver who has a current cardiovascular disease which is accompanied by and/or likely to cause symptoms of syncope, dyspnea, collapse, or congestive cardiac failure. However, the subjective decision of whether the nature and severity of an individual’s condition will likely cause symptoms of cardiovascular insufficiency is on an individual basis and qualification rests with the medical examiner and the motor carrier. In those cases where there is an occurrence of cardiovascular insufficiency (myocardial infarction, thrombosis, etc.), it is suggested before a driver is certified that he or she have a normal resting and stress electrocardiogram, no residual complications and no physical limitations, and is taking no medication likely to interfere with safe driving.

4. Coronary artery bypass surgery and pacemaker implantation are remedial procedures and thus, not medically disqualifying. Implantable cardioverter defibrillators are disqualifying due to risk of syncope. Coumadin is a medical treatment which can improve the health and safety of the driver and should not, by its use, medically disqualify the commercial motor vehicle driver. The emphasis should be on the underlying medical condition(s) which require treatment and the general health of the driver. The Federal Motor Carrier Safety Administration should be contacted at (202) 366-4001 for additional recommendations regarding the physical qualification of drivers on coumadin.

E. Respiratory Dysfunction: §391.41(b)(5)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no established medical history or clinical diagnosis of a respiratory dysfunction likely to interfere with ability to control and drive a commercial motor vehicle safely.

2. Since a driver must be alert at all times, any change in his or her mental state is in direct conflict with highway safety. Even the slightest impairment in respiratory function under emergency conditions (when greater oxygen supply is necessary for performance) may be detrimental to safe driving.

3. There are many conditions that interfere with oxygen exchange and may result in incapacitation, including emphysema, chronic asthma, carcinoma, tuberculosis, chronic bronchitis and sleep apnea. If the medical examiner detects a respiratory dysfunction, that in any way is likely to interfere with the driver’s ability to safely control and drive a commercial motor vehicle, the driver must be referred to a specialist for further evaluation and therapy. Anticoagulation therapy for deep vein thrombosis and/or pulmonary thromboembolism is not medically disqualifying once optimum dose is achieved, provided lower extremity venous examinations remain normal and the treating physician gives a favorable recommendation.

F. Hypertension: §391.41(b)(6)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no current clinical diagnosis of high blood pressure likely to interfere with ability to operate a commercial motor vehicle safely.

2. Hypertension alone is unlikely to cause sudden collapse; however, the likelihood increases when target organ damage, particularly cerebral vascular disease, is present. This regulatory criteria is based on the Federal Motor Carrier Safety Administration’s Cardiovascular Advisory Guidelines for the Examination of commercial motor vehicle Drivers, which used the Sixth Report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (1997).

3. Stage 1 hypertension corresponds to a systolic blood pressure of 140-159 mmHg and/or a diastolic blood pressure of 90-99 mmHg. The driver with a blood pressure in this range is at low risk for hypertension-related acute incapacitation and may be medically certified to drive for a one-year period. Certification examinations should be done annually thereafter and should be at or less than 140/90. If less than 160/100, certification may be extended one time for 3 months.

4. A blood pressure of 160-179 systolic and/or 100-109 diastolic is considered Stage 2 hypertension, and the driver is not necessarily unqualified during evaluation and institution of treatment. The driver is given a one-time certification of three months to reduce his or her blood pressure to less than or equal to 140/90. A blood pressure in this range is an absolute indication for anti-hypertensive drug therapy. Provided treatment is well tolerated and the driver demonstrates a blood pressure value of 140/90 or less, he or she may be certified for one year from date of the initial exam. The driver is certified annually thereafter.

5. A blood pressure at or greater than 180 (systolic) and 110 (diastolic) is considered Stage 3, high risk for an acute blood pressure-related event. The driver may not be qualified, even temporarily, until reduced to 140/90 or less and treatment is well tolerated. The driver may be certified for 6 months and biannually (every 6 months) thereafter if at recheck blood pressure is 140/90 or less.

6. Annual recertification is recommended if the medical examiner does not know the severity of hypertension prior to treatment. An elevated blood pressure finding should be confirmed by at least two subsequent measurements on different days.

7. Treatment includes nonpharmacologic and pharmacologic modalities as well as counseling to reduce other risk factors. Most antihypertensive medications also have side effects, the importance of which must be judged on an individual basis. Individuals must be alerted to the hazards of these medications while driving. Side effects of somnolence or syncope are particularly undesirable in commercial motor vehicle drivers.

8. Secondary hypertension is based on the above stages. Evaluation is warranted if patient is persistently hypertensive on maximal or near-maximal doses of 2-3 pharmacologic agents. Some causes of secondary hypertension may be amenable to surgical intervention or specific pharmacologic disease.

G. Rheumatic, Arthritic, Orthopedic, Muscular, Neuromuscular or Vascular Disease: §391.41(b)(7)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no established medical history or clinical diagnosis of rheumatic, arthritic, orthopedic, muscular, neuromuscular or vascular disease which interferes with the ability to control and operate a commercial motor vehicle safely.

2. Certain diseases are known to have acute episodes of transient muscle weakness, poor muscular coordination (ataxia), abnormal sensations (paresthesia), decreased muscular tone (hypotonia), visual disturbances and pain which may be suddenly incapacitating. With each recurring episode, these symptoms may become more pronounced and remain for longer periods of time. Other diseases have more insidious onsets and display symptoms of muscle wasting (atrophy), swelling and paresthesia which may not suddenly incapacitate a person but may restrict his/her movements and eventually interfere with the ability to safely operate a motor vehicle. In many instances these diseases are degenerative in nature or may result in deterioration of the involved area.

3. Once the individual has been diagnosed as having a rheumatic, arthritic, orthopedic, muscular, neuromuscular or vascular disease, then he/she has an established history of that disease. The physician, when examining an individual, should consider the following: The nature and severity of the individual’s condition (such as sensory loss or loss of strength); the degree of limitation present (such as range of motion); the likelihood of progressive limitation (not always present initially but may manifest itself over time); and the likelihood of sudden incapacitation. If severe functional impairment exists, the driver does not qualify. In cases where more frequent monitoring is required, a certificate for a shorter period of time may be issued.

H. Epilepsy: §391.41(b)(8)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no established medical history or clinical diagnosis of epilepsy or any other condition which is likely to cause loss of consciousness or any loss of ability to control a motor vehicle.

2. Epilepsy is a chronic functional disease characterized by seizures or episodes that occur without warning, resulting in loss of voluntary control which may lead to loss of consciousness and/or seizures. Therefore, the following drivers cannot be qualified:

(i) A driver who has a medical history of epilepsy;

(ii) A driver who has a current clinical diagnosis of epilepsy; or

(ii) A driver who is taking antiseizure medication.

3. If an individual has had a sudden episode of a nonepileptic seizure or loss of consciousness of unknown cause which did not require antiseizure medication, the decision as to whether that person’s condition will likely cause loss of consciousness or loss of ability to control a motor vehicle is made on an individual basis by the medical examiner in consultation with the treating physician. Before certification is considered, it is suggested that a 6 month waiting period elapse from the time of the episode. Following the waiting period, it is suggested that the individual have a complete neurological examination. If the results of the examination are negative and antiseizure medication is not required, then the driver may be qualified.

4. In those individual cases where a driver has a seizure or an episode of loss of consciousness that resulted from a known medical condition (e.g., drug reaction, high temperature, acute infectious disease, dehydration or acute metabolic disturbance), certification should be deferred until the driver has fully recovered from that condition and has no existing residual complications, and not taking antiseizure medication.

5. Drivers with a history of epilepsy/seizures off antiseizure medication and seizure-free for 10 years may be qualified to drive a commercial motor vehicle in interstate commerce. Interstate drivers with a history of a single unprovoked seizure may be qualified to drive a commercial motor vehicle in interstate commerce if seizure-free and off antiseizure medication for a 5-year period or more.

I. Mental Disorders: §391.41(b)(9)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no mental, nervous, organic or functional disease or psychiatric disorder likely to interfere with ability to drive a motor vehicle safely.

2. Emotional or adjustment problems contribute directly to an individual’s level of memory, reasoning, attention, and judgment. These problems often underlie physical disorders. A variety of functional disorders can cause drowsiness, dizziness, confusion, weakness or paralysis that may lead to incoordination, inattention, loss of functional control and susceptibility to accidents while driving. Physical fatigue, headache, impaired coordination, recurring physical ailments and chronic “nagging” pain may be present to such a degree that certification for commercial driving is inadvisable. Somatic and psychosomatic complaints should be thoroughly examined when determining an individual’s overall fitness to drive. Disorders of a periodically incapacitating nature, even in the early stages of development, may warrant disqualification.

3. Many bus and truck drivers have documented that “nervous trouble” related to neurotic, personality, or emotional or adjustment problems is responsible for a significant fraction of their preventable accidents. The degree to which an individual is able to appreciate, evaluate and adequately respond to environmental strain and emotional stress is critical when assessing an individual’s mental alertness and flexibility to cope with the stresses of commercial motor vehicle driving.

4. When examining the driver, it should be kept in mind that individuals who live under chronic emotional upsets may have deeply ingrained maladaptive or erratic behavior patterns. Excessively antagonistic, instinctive, impulsive, openly aggressive, paranoid or severely depressed behavior greatly interfere with the driver’s ability to drive safely. Those individuals who are highly susceptible to frequent states of emotional instability (schizophrenia, affective psychoses, paranoia, anxiety or depressive neuroses) may warrant disqualification. Careful consideration should be given to the side effects and interactions of medications in the overall qualification determination.

J. [Reserved]

K. Hearing: §391.41(b)(11)

1. A person is physically qualified to drive a commercial motor vehicle if that person: First perceives a forced whispered voice in the better ear at not less than 5 feet with or without the use of a hearing aid, or, if tested by use of an audiometric device, does not have an average hearing loss in the better ear greater than 40 decibels at 500 Hz, 1,000 Hz, and 2,000 Hz with or without a hearing aid when the audiometric device is calibrated to American National Standard (formerly ADA Standard) Z24.5-1951.

2. Since the prescribed standard under the Federal Motor Carrier Safety Regulations is from the American National Standards Institute, formerly the American Standards Association, it may be necessary to convert the audiometric results from the International Organization for Standardization standard to the American National Standards Institute standard. Instructions are included on the Medical Examination Report Form.

3. If an individual meets the criteria by using a hearing aid, the driver must wear that hearing aid and have it in operation at all times while driving. Also, the driver must be in possession of a spare power source for the hearing aid.

4. For the whispered voice test, the individual should be stationed at least 5 feet from the medical examiner with the ear being tested turned toward the medical examiner. The other ear is covered. Using the breath which remains after a normal expiration, the medical examiner whispers words or random numbers such as 66, 18, 3, etc. The medical examiner should not use only sibilants (s sounding materials). The opposite ear should be tested in the same manner.

5. If the individual fails the whispered voice test, the audiometric test should be administered. If an individual meets the criteria by the use of a hearing aid, the following statement must appear on the Medical Examiner’s Certificate “Qualified only when wearing a hearing aid.”

L. Drug Use: §391.41(b)(12)

1. A person is physically qualified to drive a commercial motor vehicle if that person does not use any drug or substance identified in 21 CFR 1308.11, an amphetamine, a narcotic, or other habit-forming drug. A driver may use a non-Schedule I drug or substance that is identified in the other Schedules in 21 CFR part 1308 if the substance or drug is prescribed by a licensed medical practitioner who:

(i) Is familiar with the driver’s medical history, and assigned duties; and

(ii) Has advised the driver that the prescribed substance or drug will not adversely affect the driver’s ability to safely operate a commercial motor vehicle.

2. This exception does not apply to methadone. The intent of the medical certification process is to medically evaluate a driver to ensure that the driver has no medical condition which interferes with the safe performance of driving tasks on a public road. If a driver uses an amphetamine, a narcotic or any other habit-forming drug, it may be cause for the driver to be found medically unqualified. If a driver uses a Schedule I drug or substance, it will be cause for the driver to be found medically unqualified. Motor carriers are encouraged to obtain a practitioner’s written statement about the effects on transportation safety of the use of a particular drug.

3. A test for controlled substances is not required as part of this biennial certification process. The Federal Motor Carrier Safety Administration or the driver’s employer should be contacted directly for information on controlled substances and alcohol testing under Part 382 of the FMCSRs.

4. The term “uses” is designed to encompass instances of prohibited drug use determined by a physician through established medical means. This may or may not involve body fluid testing. If body fluid testing takes place, positive test results should be confirmed by a second test of greater specificity. The term “habit-forming” is intended to include any drug or medication generally recognized as capable of becoming habitual, and which may impair the user’s ability to operate a commercial motor vehicle safely.

5. The driver is medically unqualified for the duration of the prohibited drug(s) use and until a second examination shows the driver is free from the prohibited drug(s) use. Recertification may involve a substance abuse evaluation, the successful completion of a drug rehabilitation program, and a negative drug test result. Additionally, given that the certification period is normally two years, the medical examiner has the option to certify for a period of less than 2 years if this medical examiner determines more frequent monitoring is required.

M. Alcoholism: §391.41(b)(13)

1. A person is physically qualified to drive a commercial motor vehicle if that person: Has no current clinical diagnosis of alcoholism.

2. The term “current clinical diagnosis of” is specifically designed to encompass a current alcoholic illness or those instances where the individual’s physical condition has not fully stabilized, regardless of the time element. If an individual shows signs of having an alcohol-use problem, he or she should be referred to a specialist. After counseling and/or treatment, he or she may be considered for certification.

Erosion vs. sediment controls: Prevent stormwater pollution at the construction site

Erosion vs. sediment controls: Prevent stormwater pollution at the construction site

It’s wintertime, and many construction sites across the U.S. face unique challenges that the season brings, especially keeping workers warm! However, one challenge that construction sites face year-round is how to keep stormwater runoff (whether it’s generated by snowmelt or rain) from transporting pollutants off-site into nearby waterways.

Under the National Pollutant Discharge Elimination System (NPDES) stormwater program (40 CFR Part 450), the Environmental Protection Agency (EPA) requires construction site operators to obtain a permit to discharge stormwater runoff into waters of the United States from any construction activity that disturbs:

  • 1 acre or more of land, or
  • Less than 1 acre of land if it’s part of a plan of development or sale that will ultimately disturb 1 or more acres of land.

Construction sites must implement best management practices (BMPs), which are controls and activities used to prevent stormwater pollution. Erosion controls and sediment controls are the two leading types of BMPs that construction sites have to apply.

Understanding the differences between erosion controls and sediment controls (and how they function together) will help you choose the most effective BMPs to reduce stormwater pollution at your construction site.

Erosion controls vs. sediment controls

Both types of controls are important, but their functions are distinct. Construction sites should use erosion controls as the primary method and sediment controls as the backup method to reduce stormwater pollution.

Erosion controls prevent the land from wearing away. These measures stop soil particles from being dislodged and transported by stormwater or wind. Erosion controls are the first line of defense against stormwater pollution.

Erosion control examples include:

  • Shoring excavated areas with retaining walls,
  • Conducting construction work in concentrated areas at different times to minimize soil exposure, and
  • Installing erosion control blankets on steep slopes.

Sediment controls capture soil particles that have been dislodged (i.e., eroded) before stormwater or wind moves them off the construction site. Sediment controls are the second line of defense, serving as backup BMPs.

Examples of sediment controls are:

  • Protecting storm drain inlets with filtering materials (such as rock-filled bags),
  • Installing fiber rolls around the perimeter to retain soil dislodged by runoff from small areas, and
  • Adding a sedimentation basin to receive dewatering discharges.

Common BMP examples

EPA’s “National Menu of Best Management Practices (BMPs) for Stormwater-Construction” webpage details erosion controls and sediment controls frequently used at construction sites, including (but not limited to) the following:

Erosion control BMPsSediment control BMPs
  • Composting blankets
  • Dust control measures (e.g., irrigation)
  • Mulching
  • Riprap (i.e., a layer of large stones)
  • Wind fences and sand fences
  • Compost filter socks
  • Rock dams
  • Sediment filters and pretreatment sediment chambers
  • Silt fences
  • Track-out controls (for construction entrances/exits)
Another popular option is vegetative cover, which can provide both erosion and sediment control. For example, a construction site can seed disturbed land to cover exposed soil (setting up temporary controls until vegetation grows). Once vegetation is established, it can stop stormwater from eroding the soil and act as a natural filter to remove sediment from the runoff.

Use both types of BMPs

The most effective way to control stormwater pollution at construction sites is by applying a selection of erosion controls and sediment controls that are coordinated to work together. Consider these examples:

  • After an area has been graded, the exposed soil must be stabilized. A site can lay sod over the exposed soil (erosion control) and install a silt fence to catch any contaminated soil moved out of the area by stormwater (sediment control) while the sod takes root.
  • Stormwater from upstream locations can flow through a construction site. To protect the disturbed land, a site can build a berm that diverts runoff away from the construction area (erosion control) to a basin where the sediment settles before the runoff is discharged (sediment control).
  • When grading an area with a slope, stormwater can transport contaminated soil down the disturbed slope. A site can install a temporary slope drain that directs the runoff at the top of the slope to a pipe that carries it down the side of the slope (erosion control). The site may also add a sediment trap at the slope drain outlet to remove sediment from the runoff before it’s released (sediment control).

Check state and local requirements

Most states issue NPDES construction stormwater permits. Additionally, some local governments may impose requirements on construction sites. However, unless the local program is designated as a qualifying local program, compliance with local regulations may not mean that your construction site is compliant with EPA’s rules (and vice versa).

Check the permit to confirm erosion control and sediment control requirements, as they may be more stringent at the state or local level.

Key to remember: Construction sites must implement erosion controls and sediment controls to prevent stormwater pollution.

Dust collector to disposal: Understanding dust as a waste stream
2026-01-28T06:00:00Z

Dust collector to disposal: Understanding dust as a waste stream

When the topic of dust is brought up, the conversation usually starts and ends with worker exposure. How much is in the air? Is ventilation adequate? Are employees protected? Once that dust has been captured and removed from the process, the critical question shifts: how should this material be classified and disposed of? That’s where many facilities run into trouble. Collected dust may no longer be floating in the air, but it hasn’t stopped being regulated. In fact, once it’s captured, dust often enters a much more complicated regulatory world.

When captured dust becomes a regulated waste

Under the Environmental Protection Agency (EPA) regulations, most collected dust qualifies as a solid waste once it’s removed from a dust collector, hopper, or filter. And despite the name, “solid waste” doesn’t mean solid, benign, or harmless. It simply means a discarded material.

At that point, facilities are expected to determine whether the dust is hazardous or non-hazardous under the Resource Conservation and Recovery Act (RCRA). This determination is based on what the dust contains, not how dusty it looks or how long it has been managed that way. Dust generated from metalworking, surface coatings, chemical processing, plastics, or specialty manufacturing can contain regulated constituents such as heavy metals or chemical residues. In these cases, facilities are required to make a waste determination using process knowledge, testing, or a combination of both.

This step is often overlooked. Many companies assume that if dust has not caused problems in the past, it must be non-hazardous. Unfortunately, regulators do not accept assumptions as documentation. If there’s no clear waste determination on file, that alone can be cited during an inspection. Misclassifying dust can also have ripple effects. If collected dust is later found to be hazardous, the facility may face issues related to improper disposal, incorrect generator status, or even cleanup liability at the disposal site. What began as a routine housekeeping task can suddenly become a significant compliance issue.

Storage, disposal, and the risks of getting it wrong

Even when dust is correctly identified as non-hazardous, it still needs to be managed properly. Open containers, poor labeling, and inconsistent handling practices are common findings during inspections. These issues are often viewed as minor, but they can quickly escalate if dust is released, mixed with other waste streams, or stored improperly.

Recycling adds another layer of complexity. Many facilities recycle metal dusts or other recoverable materials, which can be a smart environmental and economic decision. However, recyclable doesn't mean unregulated. Dust being recycled still needs to be stored safely, managed to prevent releases, and documented as legitimate recycling. Without proper controls, regulators may view the material as improperly managed waste.

Outdoor storage creates additional risk. Dust stored outside, transferred outdoors, or tracked out of the building can easily become a stormwater concern. Even non-hazardous dust can be considered a pollutant if it migrates off-site during rain events. This is a frequent source of violations under stormwater permits and Stormwater Pollution Prevention Plans (SWPPPs), especially when dust management isn’t addressed in the SWPPP.

Another common issue is mixing dust with general trash or other waste streams. Once mixed, otherwise manageable dust can become more difficult or impossible to classify correctly. This can complicate disposal, increase costs, and raise questions during audits or inspections.

What makes dust especially challenging is that responsibility for it often falls into a gray area. The safety team may assume that the environmental team is managing disposal. The environmental team may assume that the safety team has already classified the material. When no one clearly owns the waste determination and disposal process, gaps are almost guaranteed.

The most effective facilities treat dust as a waste stream that deserves the same attention as any other regulated material. They document waste determinations, define storage and labeling requirements, train employees on proper handling, and periodically revisit those determinations as processes change.

Keys to remember: Captured dust doesn’t stop being regulated once it leaves the air. Understanding whether collected dust is hazardous or non-hazardous, how it must be stored, and where it can legally go is essential to staying compliant.

California codifies requirements for pesticide applications near schools

Effective date: January 1, 2026

This applies to: Pesticide applications made for agricultural commodity production within ¼ mile of a school

Description of change: Assembly Bill 1864 (effective January 1, 2025) regulates pesticide applications for the production of agricultural commodities within ¼ mile of a school.

The amendments to the rule require applicants to:

  • Obtain a separate site identification number for the part of an agricultural field within ¼ mile of a “schoolsite," and
  • List the anticipated method of application for notices of intent and pesticide use reports.

Further, the amendments change the definition of “schoolsite” to include private schools that serve six or more students (kindergarten through grade 12), which will become effective on December 31, 2026.

2026-01-28T06:00:00Z

Washington adopts regulations for battery collection program

Effective date: January 16, 2026

This applies to: Producers of batteries and battery-containing products

Description of change: The Washington Department of Ecology adopted a new rule for the Battery Stewardship Program, required by a law passed in 2023 to establish an extended producer responsibility program for battery collection. The regulations implement the law, requiring battery producers to fund a statewide recycling program with collection sites where people can drop off used or unwanted batteries.

Covered batteries include most rechargeable and single-use batteries that people use daily (e.g., AAs, AAAs, Cs, Ds, 9-Volts, and button batteries). The regulations also cover battery-containing products.

The new rule establishes program requirements (e.g., adding required information on batteries), applicable fees, and battery collection and handling standards. It requires battery producers to join and fully fund a nonprofit to serve as a Battery Stewardship Organization, which administers the program.

Proposal expected: OSHA to step away from costly fixed-ladder deadline
2026-01-26T06:00:00Z

Proposal expected: OSHA to step away from costly fixed-ladder deadline

OSHA is fast-tracking a proposed rule to remove a 2036 mandate to upgrade fall protection systems on fixed ladders that extend over 24 feet. The agency says the change, sparked by an industry petition, would allow employers to update their ladders at the end of their service lives, rather than by a hard compliance date. OSHA frames the move as deregulatory.

The affected regulation, 29 CFR 1910.28(b)(9)(i)(D), currently reads: “(i) For fixed ladders that extend more than 24 feet (7.3 m) above a lower level, the employer must ensure: … (D) Final deadline. On and after November 18, 2036, all fixed ladders are equipped with a personal fall arrest system or a ladder safety system.”

What’s happened?

A quick look at the rule’s development shows:

  • 7/28/2025 — OSHA received a petition for rulemaking that covers obligations for ladder retrofits under 1910.28(b)(9).
  • 9/15/2025 — OSHA posted a memo confirming it intends to eliminate 1910.28(b)(9)(i)(D).
  • 12/18/2025 — OSHA sent its Walking-Working Surfaces (WWS) - Fixed Ladders proposal to the Office of Management and Budget (OMB) Office of Information and Regulatory Affairs (OIRA).
  • 1/13/2026 — OIRA and OSHA met with the American Fuel and Petrochemical Manufacturers (AFPM).
  • 1/21/2026 — OIRA and OSHA met with the Employers OSHA Modernization Coalition.
  • 1/27/2026 — OIRA plans to meet with attorneys representing the American Petroleum Institute (API).

What did the petition request?

The seven-page petition, written by legal counsel on behalf of the AFPM, API, and American Chemistry Council (ACC), requests that OSHA:

  • Withdraw the provision under the WWS standard for fixed ladders that extend more than 24 feet to be equipped with personal fall arrest systems (allowing the continued use of ladder cages or wells); or
  • Grandfather fixed ladders installed before a particular date (authorizing the continued use of existing ladder cages or wells for those ladders).

Unjustified provision?

Petitioners argue that OSHA, in its 2010 proposed WWS rule, failed to:

  • Take comments on the effectiveness of cages in protecting workers from falls,
  • Disclose that the agency was evaluating whether to prohibit cages, and
  • Give stakeholders a chance to submit evidence regarding cages.

The petition outlines the differences between the earlier proposed and final rules, noting that the 2010 proposal gave employers the choice to use any of four fall-protection types — cages, wells, ladder safety systems, or personal fall protection systems. However, the 2016 final rule gave a 2036 phase-out date for cages and wells.

The petition goes on to contend that:

  • OSHA lacks sufficient evidence to justify prohibiting cages and wells;
  • Data collected during the rulemaking process leaned toward preserving employer choices for fall protection; and
  • Although the 2016 rulemaking preamble acknowledged the shift away from cages and wells, it did not fully discuss evidence in favor of cages and wells.

Other arguments in the petition

The petition raises several points questioning the benefits of paragraph (b)(9)(i)(D), stating that:

  • In the past decade, AFPM, API, and ACC facilities have suffered only a few injuries, with no fatalities involving cages and wells;
  • Cages offer passive protection, whereas ladder safety systems and personal fall arrest systems require workers to take action to comply;
  • Personal protective equipment (PPE) lies at the bottom of the hierarchy of controls;
  • Safety risks also exist for ladder safety systems and personal fall arrest systems; and
  • Installing new ladders or retrofitting existing ones introduces hazards to those performing that work.

Finally, the petition addresses significant compliance costs, estimating several billion dollars for tens of thousands of ladders at U.S. refineries alone. Petitioners also cited additional expenses for rerating pressure vessels and engineering any process equipment changes.

What does OSHA say?

OSHA officially announced in a September 2025 memo that it is proposing to remove 1910.28(b)(9)(i)(D). The agency calls it a deregulatory action in line with Executive Order 14192. The memo reasons, “OSHA anticipates this change will allow employers to update their ladders when the ladders reach the end of their service lives, accommodating the lengthy service life of fixed ladders, while significantly reducing costs and offering greater flexibility.”

The WWS - Fixed Ladders proposal reached OIRA on December 18. OIRA typically takes 90 to 120 days for review, but recently a maximum 28-day review period for deregulatory actions was implemented. That means we anticipate OIRA will rush this proposal, so that OSHA may publish it in the Federal Register.

Key to remember

An upcoming OSHA proposal would withdraw 1910.28(b)(9)(i)(D). The rule was spurred by a petition.

Wildfire air pollution is rising: What federal findings mean for industry compliance

Wildfire air pollution is rising: What federal findings mean for industry compliance

Wildfires have become one of the largest drivers of elevated air pollution in the United States, and recent federal publications show that their impact is increasing in both scale and severity. EPA confirms that large and catastrophic wildfires now produce substantial increases in fine particulate matter (PM2.5) across broad regions of the country, including smoke transported from Canada and Mexico. These events are raising background PM2.5 levels and expanding the number of communities experiencing smoke each year. As these trends accelerate, industries face new challenges in compliance, permitting, and worker protection, especially as wildfire seasons grow longer and smoke events more frequent.

Federal research shows PM2.5 from wildfires increasing nationwide

EPA’s most recent wildfire smoke analysis shows clear year to year increases in PM2.5 concentrations attributed to wildfire smoke across the United States. Data from 2006–2020 demonstrate that smoke driven PM2.5 spikes are occurring more often and across a wider geographic footprint. The agency reports that national public health impacts are significant, with thousands of annual emergency room visits, hospitalizations, and deaths linked to wildfire smoke exposure.

The National Oceanographic and Atmospheric Administration’s (NOAA’s) 2025 federal wildfire smoke review supports these findings. Using space-based instrumentation GOES 19, TEMPO, and other satellite scientific tools, NOAA shows that thick smoke plumes from Canadian and U.S. fires degraded air quality across the Upper Midwest and other regions, even hundreds of miles from the fires. These satellite observations are paired with EPA ground monitors to identify high pollution zones and support air quality alerts.

Together, EPA and NOAA findings confirm that wildfire smoke is a major and rising contributor to PM2.5 levels, which is important for industries located in or downwind of wildfire prone areas.

Exceptional events

A central compliance question for industry is whether wildfire related pollution counts toward National Ambient Air Quality Standards (NAAQS) attainment. Under the Exceptional Events Rule, wildfire smoke can be excluded from NAAQS determinations if states demonstrate that exceedances were caused by an uncontrollable natural event. EPA’s wildfire smoke guidance highlights the increasing burden of documenting smoke impacts and shows how PM2.5 spikes related to fires have grown more common.

The agency acknowledges that wildfire smoke frequently pushes PM2.5 concentrations into unhealthy ranges. During the 2023 Canadian wildfire episode, for example, EPA referenced surveillance showed measurable increases in asthma related emergency room (ER) visits. Even when these pollution spikes qualify as exceptional events, they still influence public health, air quality planning, and operational decisions for industry.

At the same time, NOAA continues to refine federal smoke forecasting models used by the National Weather Service (NWS) and EPA. These models help states prepare exceptional event documentation and guide industrial contingency planning when wildfire smoke is anticipated.

Why industry EHS professionals should pay close attention

  • Compliance and attainment risk: Wildfire smoke may be excluded as an exceptional event, but elevated PM2.5 levels can still push a region toward nonattainment before exclusion is approved. This creates uncertainty for industries during permit renewals, emissions modeling, and long-term facility planning. EPA’s data clearly indicate that wildfire driven PM2.5 exceedances are rising nationwide.
  • Worker exposure and health risk: EPA and NOAA findings confirm that wildfire smoke carries fine particulate matter capable of worsening respiratory and cardiovascular conditions. Industries with outdoor workers must consider revised exposure protocols, respirators, and schedule adjustments during smoke episodes.
  • Operational and supply chain stability: NOAA’s wildfire smoke analysis shows that smoke can travel long distances, disrupt visibility, affect logistics, and degrade regional air quality for days or weeks. Companies dependent on transportation corridors or sensitive equipment should plan for smoke related delays and monitoring.
  • Community and stakeholder expectations: Even when deemed an exceptional event, wildfire smoke contributes to local risk perceptions. Facilities may face increased scrutiny, especially if their emissions interact with elevated regional PM2.5.

Bottom line for industry

Federal research shows that wildfire driven air pollution is increasing in both frequency and intensity, often raising PM2.5 concentrations across entire regions. EPA’s Exceptional Events Rule may exclude wildfire smoke from NAAQS compliance, but industries still face operational, health, and planning challenges as wildfire seasons intensify. NOAA’s satellite data confirms that smoke impacts will continue to widen under changing climate conditions.

Key to remember: For EHS professionals, wildfire smoke is no longer only a regional hazard. It is a strategic compliance and operational issue requiring enhanced monitoring, seasonal planning, and proactive communication.

Defining RCRA solid waste: Does your material qualify?
2026-01-15T06:00:00Z

Defining RCRA solid waste: Does your material qualify?

What’s a solid waste? It may seem obvious at first, but understanding the correct definition is essential for facilities to comply with the federal waste management program. If the question is answered incorrectly, there can be serious consequences. Mismanaged waste (especially when it’s hazardous) can endanger the health of people and the environment.

Under the Resource Conservation and Recovery Act (RCRA), the Environmental Protection Agency (EPA) regulates the entire lifecycle of waste, from creation to disposal. Only materials that qualify as “solid waste” — whether they’re nonhazardous or hazardous — are subject to RCRA requirements. That’s why all waste generators need to have an accurate understanding of how solid waste is defined.

Use this overview to help your facility determine if the waste it generates qualifies as solid waste.

What’s a RCRA solid waste?

The statutory definition (42 U.S.C. 6903(27)) and the regulatory definition (40 CFR 261.2) explain what’s considered a solid waste under RCRA.

Statutory definition

The act defines solid waste as:

  • Garbage;
  • Refuse;
  • Sludge from a waste treatment plant, water supply treatment plant, or air pollution control facility; or
  • Any other discarded material from industrial, commercial, mining, and agricultural operations and from community activities.

It applies to physically solid, semisolid, liquid, and gaseous materials.

Regulatory definition

EPA (per 262.11) requires anyone who generates a solid waste to accurately determine whether the waste is hazardous. The first part of the hazardous waste identification process is to establish whether the material is a solid waste. EPA expanded the definition of solid waste for this purpose.

The regulation further defines solid waste as any material that’s discarded by being:

  • Abandoned (defined in 261.2(b)),
  • Recycled (defined in 261.2(c)),
  • Considered inherently waste-like (defined in 261.2(d)), or
  • A military munition (defined in 266.202).

If a material doesn’t meet these criteria, it’s not considered a solid waste and isn’t subject to RCRA regulations. If the criteria do apply, the material qualifies as a RCRA solid waste, and your facility must comply with EPA’s standards for managing either nonhazardous or hazardous RCRA waste.

What’s not a RCRA solid waste?

Many materials are excluded from the definition of solid waste. However, that doesn’t necessarily mean that these wastes are unregulated; some are excluded because other regulations apply (for example, industrial wastewater point source discharges are subject to the National Pollutant Discharge Elimination System rules). Make sure to check if other requirements apply to excluded materials.

Statutory exclusions

RCRA’s definition of solid waste excludes:

  • Solid or dissolved material in domestic sewage;
  • Solid or dissolved materials in irrigation return flows;
  • Industrial wastewater discharges only at point sources (it doesn’t exclude industrial wastewaters collected, stored, or treated before discharge or sludges generated by industrial wastewater treatment); and
  • Source, special nuclear, or byproduct material defined by the Atomic Energy Act.

Regulatory exclusions

EPA lists the wastes that are exempt from the definition of solid waste at 261.4. It excludes all of the wastes that the statutory definition does. The agency also exempts other wastes under certain conditions (such as spent sulfuric acid used to produce virgin sulfuric acid, reclaimed secondary materials reused in production, and recycled shredded circuit boards).

Why does this matter?

Knowing what’s considered solid waste is vital to compliance because it tells you if RCRA rules apply to your specific waste.

It’s also the first part of the hazardous waste identification process. Facilities use the process to determine how solid waste is regulated, either as nonhazardous waste subject to RCRA Subtitle D rules or as hazardous waste subject to RCRA Subtitle C standards.

Check state requirements

Most states implement the RCRA waste management regulations. State rules must be at least as strict as federal, and some states may have more stringent requirements. Check with your facility’s state environmental agency to confirm what standards apply.

Key to remember: Defining solid waste is the first step in determining whether RCRA rules apply to a material.

EPA scraps SDS/Tier II reporting rule tied to OSHA HazCom
2026-01-14T06:00:00Z

EPA scraps SDS/Tier II reporting rule tied to OSHA HazCom

After receiving an “adverse comment,” EPA withdrew its direct final rule to amend 40 CFR 370 before the rule had a chance to take effect. The direct final rule published back on November 17, 2025, was intended to relax the Tier II reporting and safety data sheet (SDS) reporting requirements and align with the OSHA Hazard Communication standard at 29 CFR 1910.1200.

In November, EPA said it considered the rule to be noncontroversial and anticipated no adverse comment. However, on January 9, 2026, EPA published its withdrawal of the direct final rule “because the EPA subsequently received adverse comment.” The agency did not disclose what the fatal comment was. However, docket EPA-HQ-OLEM-2025-0299 shows nine comments, many of which express serious concerns with this rule related to the Emergency Planning and Community Right-to-Know Act (EPCRA).

What were the objections?

Examining the docket, we find several requests for withdrawal of the rule. Some of the concerns raised by commenters included:

  • Misalignment with OSHA compliance dates — Commenters remarked that the rule does not align with the phased-in compliance deadlines in the OSHA Hazard Communication (HazCom) standard at 29 CFR 1910.1200(j). In fact, EPA’s compliance date precedes OSHA’s dates, making it “impossible to implement the required changes … for the 2026 reporting cycle,” asserted one commenter. This will force facilities to engage in premature self-classification, argued the commenter. “This misalignment introduces a high risk of inconsistent hazard reporting, undermining both regulatory clarity and the reliability of emergency planning data,” warned another.
  • Unrealistic timeline — Commenters pointed out the fast-track schedule. “This timeline compresses the window for implementing critical updates to chemical management software systems [and] procedures [and] reconfiguring data collection processes,” explained a commenter who predicted that facilities will be unable to ensure compatibility between internal chemical management software systems and the new reporting structure, without timely access to updated EPA-provided Tier2Submit® software.
  • Implementation challenges — Facilities would be mandated to re-map each reported chemical (often before SDSs have been updated), claimed one commenter. State agencies would also have to incorporate the new hazard categories into their electronic reporting systems and revise guidance/training materials, according to another.
  • New burdens with little benefit — While EPA announced that the rule was deregulatory, one commenter contends that it would make reporting “MORE burdensome.” The commenter also stressed that the rule would “not improve emergency planning or response.” Others emphasized that it exceeds what is necessary for harmonization with the OSHA HazCom standard and that the expanded reporting system would offer “little value.” Yet another commenter noted that using 112 hazard categories instead of 24 would overwhelm the public who have a right to know about the hazards in their communities.
  • Rule characterization flaws — One commenter declared that “the rule’s characterization as ‘technical’ does not withstand scrutiny” because it substantively changes what information must be submitted; imposes non-trivial, potentially large costs on both the private sector and state/local programs; and conflicts with OSHA’s phased compliance framework.
  • EPA obligation failures — Commenters also observed that EPA failed to assess or recognize “potentially large aggregate costs to the private sector and to state/local [agencies].” They also suggest that the agency estimate paperwork costs, determine whether small entities are affected, and request the Office of Management and Budget to review the rule. Finally, EPA has not meaningfully looked at costs and least-cost alternatives, one commenter said. The commenter gave alternative examples — “phased implementation aligned to OSHA’s schedule, optional dual-category reporting for one cycle, or a later effective date.”

What’s next?

Now, EPA is proceeding with writing a new final rule addressing all public comments. The agency published a parallel proposed rule on the same November date as the direct final rule. That proposal took comments (through December 24, 2025) on the substance of the direct final rule.

That means the agency has all it needs to work on a final rule. EPA made clear that no second round of comments will be collected, but the agency gave no hints as to when it might publish a new final rule.

Until then, the existing CFRs remain in place. In other words, the changes in the November 17, 2025, direct final rule will not take effect on January 16, 2026, as planned because they are now withdrawn.

Note that the direct final rule, had it taken effect, would not have impacted the Tier II forms due on or before March 1, 2026. Rest assured that it is “business as usual” for Tier II reporting due by March 1, 2026. Similarly, SDS reporting requirements continue as is.

For background information, check out our November 25th article, “EPA’s SDS/Tier II reporting now in lockstep with OSHA HazCom.”

Key to remember

On January 9th, EPA withdrew the November 17th direct final rule that would have amended Part 370. The withdrawal is prompted by an adverse comment. A new final rule is in the works.

Understanding WOTUS and Navigable Waters in 2026
2026-01-12T06:00:00Z

Understanding WOTUS and Navigable Waters in 2026

Federal Clean Water Act (CWA) coverage is narrowing after the Supreme Court’s Sackett v. Environmental Protection Agency (Sackett) decision (2023) and a 2025 Environmental Protection Agency (EPA)/U.S. Army Corps of Engineers (USACE) proposal to align waters of the United States (WOTUS) with that ruling. Expect fewer federally regulated wetlands, more state-by-state differences, and continued uncertainty through 2026.

What counts as “navigable waters” today?

Post-Sackett, WOTUS includes traditional navigable waters, territorial seas, certain interstate waters, impoundments, tributaries that are relatively permanent, and adjacent wetlands that directly abut those waters through a continuous surface connection. Non-jurisdictional ditches do not create adjacency.

Recent changes

  • Supreme Court decision in Sackett (May 2023): The CWA covers only waters that are relatively permanent and wetlands with a continuous surface connection to those waters. The Supreme Court rejected the “significant nexus” test.
  • Conforming amendments (September 2023): EPA and the USACE removed the significant nexus standard, revised the definition of "adjacent," and clarified that interstate wetlands aren't automatically WOTUS.
  • Field guidance (March 2025): EPA and the USACE directed that non-jurisdictional ditches, swales, pipes, and culverts don't create a continuous surface connection. Wetlands must directly abut the water.
  • Proposed rule (November 2025): EPA and the USACE proposed definitions for “relatively permanent,” “tributary,” and “continuous surface connection.” If finalized, federal coverage will narrow further.

Where each rule applies

Implementation is split:

  • The 2023 amended rule is in effect in 24 states, D.C., and territories.
  • The pre-2015 regime and Sackett apply in 26 states, including Alabama, Alaska, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, and Wyoming.

Kentucky now follows the 2023 amended rule except for certain litigants. Always check EPA’s “Current Implementation of Waters of the United States” page to check state status before filing permits.

Why it matters to industry and commerce

  • Permitting: WOTUS defines whether projects need Section 404 (dredge/fill) and Section 402 (National Pollutant Discharge Elimination System) permits. A narrower federal scope can reduce federal permitting, but state and tribal programs may still apply.
  • Design: Wetlands separated by berms or uplands and connected only by ditches or culverts likely do not qualify as WOTUS. Early jurisdictional determinations (JDs) and hydrologic documentation are critical.
  • Risk: Multistate portfolios face uneven rules due to individual states having their own regulatory framework. The 2025 proposal could further limit federal reach, shifting responsibility to states. Multistate industry and commerce should prepare for state variability and litigation-driven changes.

The legal and regulatory arc: Why definitions keep changing

  • Statute: The CWA regulates “navigable waters,” defined as “waters of the United States,” but doesn't define WOTUS.
  • Court history: Court decisions have repeatedly reshaped and narrowed the definition of WOTUS. United States v. Riverside Bayview Homes, Inc. (1985) upheld adjacent wetlands; the scope narrowed when Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (2001) limited isolated waters. Rapanos v. United States (2006) deepened uncertainty by introducing two competing tests, “relatively permanent” vs. “significant nexus,” leaving regulators and courts with ambiguity.
  • Rulemaking swings:
    • The 2015 Clean Water Rule broadened coverage.
    • The 2020 Navigable Waters Protection Rule narrowed it, but the rule was later vacated.
    • The 2023 WOTUS Rule was reshaped by Sackett and amended in August 2023.
  • Current alignment: The 2023 amendments and 2025 proposal aim to match the Supreme Court’s standards.

Pending actions to watch in 2026

  • Final rule: The 2025 proposal’s comment period closed on January 5, 2026. A final rule could standardize terms and further narrow jurisdiction.
  • Litigation: Courts may lift or expand injunctions, changing which states apply which regime.
  • Funding: Fiscal Year 2025 operations rely on continuing resolutions; WOTUS changes will come through rulemaking, not budget riders.

Practical steps for EHS and project teams

  • Confirm your state’s regime before scoping.
  • Request or update JDs early; document permanence and direct abutment.
  • Track the 2025 proposal and submit comments where unclear.

Key to Remember: WOTUS and “navigable waters” definitions are narrowing, reducing some federal burdens but increasing state variability. For industrial and commercial projects, early jurisdictional work and state-specific permitting plans are essential to protect schedules and budgets.

EHS Monthly Round Up - December 2025

EHS Monthly Round Up - December 2025

In this December 2025 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 last month.

In fiscal year 2025, the top three violations for non-construction small employers, those with under 100 employees, were hazard communication, respiratory protection, and powered industrial trucks. Three industries dominated these violations: fabricated metal product manufacturing, repair and maintenance, and non-metallic mineral product manufacturing.

OSHA issued several new letters of interpretation on a variety of workplace topics, including permit required confined spaces, recordkeeping, and powered industrial trucks. Letters of interpretation help ensure the consistent application of federal workplace safety and health standards, and provide regulatory clarification to employers, workers, and safety professionals.

California’s STOP Act took effect January 1. The law targets the state’s fabricated stone industry. It prohibits dry cutting of stone countertops, mandates employee training, and classifies silicosis and silica-related lung cancer from artificial stone as a serious injury or illness.

As of January 1, Washington state requires tower crane permits for all construction work involving tower crane operation, assembly, disassembly, and reconfiguration. Before issuing permits, Washington Department of Labor and Industries will conduct safety conferences to ensure all parties understand the safety requirements and related responsibilities.

Turning to environmental news, EPA issued compliance deadline extensions for certain emissions standards. The delays affect the New Source Performance Standards for crude oil and natural gas facilities and the emissions guidelines for such facilities. Compliance timelines have been pushed into mid- to late-2026 and early 2027.

And finally, although EPA has been deregulating or loosening some environmental requirements, there are still some standards being tightened. These include renewable fuel standards, stormwater management, and PFAS disclosure. Changes to these requirements will reshape compliance obligations for U.S. companies in 2026, and reflect a trend toward increased transparency and environmental accountability.

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

EHS Monthly Round Up - January 2025

EHS Monthly Round Up - January 2025

In this January 2025 monthly 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. There’s a lot going on, so let’s get started!

As happens at the start of most incoming presidential administrations, a freeze has been placed on all regulatory activity at the federal level, giving the new administration time to review agencies’ plans. The Office of Management and Budget, which must approve most rulemaking activities, has sent numerous pending rules back to the agencies for review. In addition, OSHA withdrew its infectious diseases proposed rule and its COVID-19 in healthcare rule prior to the inauguration.

OSHA’s penalties increased on January 15. The maximum penalty amounts for serious and other-than-serious violations increased to $16,550. For willful or repeated violations, the maximum penalty increased to $165,514 per violation.

OSHA updated its directive on injury and illness recordkeeping policies and procedures. While it’s intended for OSHA compliance officers, employers can use the information to help with recordkeeping compliance.

Fewer workers died on the job in 2023, as fatal work injuries decreased 3.7 percent from 2022. Transportation incidents remained the most frequent type of fatal event, accounting for over 36 percent of all occupational fatalities.

California’s Occupational Safety and Health Standards Board voted to adopt a permanent silica standard. If approved, it would extend and strengthen the state’s emergency temporary standard, which was put in place in December 2023.

The National Institute for Occupational Safety and Health updated its List of Hazardous Drugs in Healthcare Settings. This is a resource for employers and employees in identifying drugs that are hazardous to the health and safety of those who handle them.

Turning to environmental news, EPA released the biannual update of the nonconfidential TSCA inventory. The inventory helps facilities determine their regulatory requirements for the chemicals they use or plan to use.

And finally, EPA added new Management Method Codes to describe how hazardous waste will be managed after temporary storage and transfer. As of January 1st, hazardous waste handlers must use the codes on the Biennial Report Waste Generation and Management forms.

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

EPA extends wastewater compliance deadlines for coal-fired steam power plants

The Environmental Protection Agency (EPA) published a final rule on December 31, 2025, that changes certain requirements for wastewater discharges from coal-fired steam electric power plants. It applies to regulations established by the preceding rule finalized in 2024.

The 2025 final rule:

  • Extends the submission deadline for the notice of planned participation (NOPP) required for the subcategory of electric generating units (EGUs) seeking to permanently stop coal combustion by December 31, 2034;
  • Extends compliance deadlines for zero-discharge limitations that apply to dischargers of flue gas desulfurization (FGD) wastewater, bottom ash (BA) transport water, and combustion residual leachate (CRL);
  • Establishes tiered standards for indirect discharges of FGD wastewater, BA transport water, and CRL; and
  • Adds provisions that allow facilities to transfer into and out of the subcategory of regulated EGUs that will permanently cease coal combustion by 2034 until December 31, 2034.

Who’s affected?

The final rule impacts EGUs subject to the effluent limitations guidelines and standards for the steam electric power generating point source category (40 CFR Part 423).

What are the new deadlines?

The 2025 final rule delays the NOPP compliance date. It also extends the deadlines for zero-discharge limitations on FGD wastewater, BA transport water, and CRL. The delays apply to the best available economically achievable (BAT) limitations for direct dischargers and the pretreatment standards for existing sources (PSES) for indirect dischargers.

  • CRL PSES

What are the other changes?

EPA’s 2025 final rule sets tiered standards for indirect dischargers of FGD wastewater, BA transport water, and CRL:

  • The first tier requires indirect dischargers to meet pre-2024 final rule standards by January 1, 2029.
  • The second tier:
    • Allows indirect dischargers to continue indirectly discharging up to December 31, 2024, if they certify that they’ll convert to become direct dischargers; or
    • Requires indirect dischargers to meet the zero-discharge requirements by January 1, 2029, if they choose not to become direct dischargers.

The final rule also adds provisions that enable facilities to transfer into and out of the subcategory of regulated EGUs that will permanently cease coal combustion by 2034 until December 31, 2034. It allows EGUs to switch between complying with the zero-discharge limitations and the requirements that apply to the subcategory.

Key to remember: EPA has delayed certain compliance requirements for coal-fired steam electric power plants that discharge three types of wastewaters.

New York establishes Mandatory Greenhouse Gas Reporting Program

Effective date: December 10, 2025

This applies to: Certain GHG emission sources

Description of change: Entities subject to 6 NYCRR Part 253 must submit annual reports of greenhouse (GHG) emissions during the previous calendar year by June 1. Reporting facilities must keep records used for the reports, and larger sources have to obtain third-party verification of their reported emissions. The first report will cover 2026 GHG emissions data and will be due on June 1, 2027.

The regulation applies to emission sources that are in a listed category and operate in New York. The rule establishes three reporting threshold categories:

  • Suppliers of fuels, electricity, or fertilizer;
  • Facilities that emit more than 10,000 metric tons of carbon dioxide equivalent of GHGs annually; and
  • Sources with a specific operational activity.
