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.

Most Recent Highlights In Environmental

EHS Monthly Round Up - January 2023

EHS Monthly Round Up - January 2023

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

Hi everyone! Welcome to the monthly roundup video, where we’ll review the most impactful environmental, safety, and health news. First, let’s take a look at what’s happening in safety and health.

If you haven’t already done so, now is the time to post your OSHA 300A Summary. Employers are required to post the Summary in a conspicuous place from February 1st through April 30th.

As required by law, OSHA increased its penalties for inflation in mid-January. Penalties went up 7.7 percent, effective January 17th.

Also in January, OSHA released its long-awaited Fall 2022 regulatory agenda. Along with numerous proposed rules in the works, three major final rules are slated for 2023 – COVID-19 in healthcare, Injury and Illness tracking, and an update to the hazard communication standard.

OSHA recently released two new letters of interpretation, which address exit signs and lockout/tagout. Specifically, OSHA states that the International Standards Organization emergency exit symbol can be located beside the mandatory EXIT text on an existing sign.

The second letter addresses the applicability of lockout/tagout and the maintenance and operations of cathodic protection rectifiers when working on pipelines.

New York’s Warehouse Worker Protection Act was signed into law in December and takes effect in late February. It protects warehouse distribution workers from undisclosed or unlawful work speed quotas and includes protections for workers who fail to meet these quotas.

In 2021, a worker died every 101 minutes from a work-related injury, according to the Bureau of Labor Statistics. A total of 5,190 fatal work injuries was recorded in the U.S. in 2021, an 8.9 percent increase over 2020.

Turning to environmental news, EPA automatically added nine per- and polyfluoroalkyl substances, or PFAS, to the Toxics Release Inventory, or TRI, list. Four PFAS were added since they are no longer claimed as confidential business information.

EPA released its Fall 2022 regulatory agenda in early January. Included are major regulations impacting the National Ambient Air Quality Standards, waters of the United States, and modifications to the Risk Management Program under the Clean Air Act.

There are also a number of rules related to the National Emission Standards for Hazardous Air Pollutants in various rule stages.

And finally, beginning with model year 2027, heavy-duty trucks will be required to meet clean air standards that are 80 percent more stringent than current requirements.

EPA says this final rule is aimed at reducing smog- and soot-forming emissions, increasing the life of governed vehicles by up to 250 percent, and increasing emissions warranty periods up to 450 percent.

Thanks for tuning in to the monthly news roundup!

Tennessee establishes waste tire hauler registration program

Effective date: January 18, 2027

This applies to: Waste tire generators, commercial waste tire haulers, and permitted waste tire management facilities

Description of change: The Tennessee Underground Storage Tanks and Solid Waste Disposal Control Board approved regulations establishing a waste tire hauler registration program that tracks and regulates the transportation of waste tires from the point of generation to the delivery for permitted storage, processing, or disposal.

The regulations include:

  • Administrative requirements for registration;
  • Decal requirements for vehicles that commercially haul waste tires;
  • An annual registration fee for registered waste tire hauler vehicles;
  • Terms and conditions for registered waste tire haulers;
  • Manifest requirements for all waste tire generators, transporters, and permitted waste tire management facilities; and
  • Financial assurance requirements for registered waste tire haulers.
2026-11-02T06:00:00Z

California adopts regulations for initial corporate GHG report

Effective date: October 12, 2026

This applies to: U.S.-based companies that do business in California with total annual revenues above $1 billion (reporting entities) and with total annual revenues above $500 million (covered entities)

Description of change: The California Office of Administrative Law (OAL) approved the California Corporate Greenhouse Gas Reporting and Climate-Related Financial Risk Disclosure Initial Regulation, which was approved by the California Air Resources Board (CARB) in February 2026.

The adopted regulations help implement the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Reporting Act, which require U.S.-based companies operating in California to report greenhouse gas (GHG) emissions and climate-related financial risks.

The regulation:

  • Establishes annual fee calculations and procedures,
  • Specifies definitions to help entities determine applicability (whether the rule applies and if they must comply with both emissions reporting and fee requirements), and
  • Sets the first-year reporting deadline of November 10, 2026, for reporting Scope 1 and Scope 2 GHG emissions.

Annual report

CARB has sent a reminder letter to organizations potentially required to sumbit the inital report by November 10, 2026.

Entities that weren’t collecting data or weren’t planning to collect data when CARB issued its December 2024 Enforcement Notice aren’t expected to submit Scope 1 and 2 reporting data for this first reporting cycle in 2026 only.

Starting in 2027, reporting entities must annually disclose Scope 1, Scope 2, and Scope 3 GHG emissions for the previous fiscal year. CARB is developing reporting regulations for 2027 and later.

Annual fee

Reporting entities and covered entities must pay the applicable annual implementation fee within 60 calendar days of receiving a fee determination notice from CARB.

Federal environmental reporting: 5 annual reports due in 2027
2026-11-02T06:00:00Z

Federal environmental reporting: 5 annual reports due in 2027

With the new year quickly approaching, many businesses take time to reflect on the previous year to evaluate their performance. For numerous facilities subject to federal environmental regulations, this isn’t just a good practice; it’s mandated through annual reporting requirements.

Mark your compliance calendars for these common federal environmental annual reports due in 2027.

Multi-Sector General Permit (MSGP) annual report

Due: January 30, 2027

EPA issues industrial stormwater MSGPs in areas where it serves as the permitting authority. Examples include Massachusetts, New Hampshire, New Mexico, and the District of Columbia.

Facilities with MSGPs must submit the Annual Report for Stormwater Discharges Associated with Industrial Activity Under the NPDES MSGP (NPDES Form 6100-28) electronically via the NPDES Electronic Reporting Tool (NeT). The report covers information from calendar year 2026.

Take note! EPA has administratively continued the 2021 MSGP for facilities covered under the permit before it expired in February 2026.

New facilities must comply with the requirements in EPA’s No Action Assurance for New Industrial Facilities Needing Stormwater Permit Coverage under EPA’s Multi-Sector General Permit memorandum (issued February 27, 2026) until the agency issues a new MSGP. The memorandum mandates facilities to provide the electronically reported information required by the 2021 MSGP (including the annual report) if EPA requests it.

Emergency and Hazardous Chemical Inventory (Tier II Inventory Report)

Due: March 1, 2027

Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA) requires covered facilities to submit the Tier II Inventory Report (or a state-equivalent form) to the State Emergency Response Commission, Local Emergency Planning Committee, and local fire department. Reporting applies to facilities:

  • That are required by OSHA’s Hazard Communication standard (29 CFR 1910.1200) to prepare or have available Safety Data Sheets (SDSs), and
  • That have on-site at any one time hazardous substances (EHSs) or non-EHS hazardous chemicals at or above certain thresholds (40 CFR Part 370 Subpart B).

The report provides information on the covered hazardous chemicals used or stored at the facility in 2026, including locations, amounts, and potential hazards.

Take note! Facilities should check state regulations to:

  • Confirm Tier II reporting thresholds, as they may be more stringent;
  • Determine whether any additional chemicals are covered; and
  • Verify how the report must be submitted, including whether states accept Tier2 Submit files.

Hazardous Waste Export Annual Report

Due: March 1, 2027

The Resource Conservation and Recovery Act (RCRA) requires exporters of regulated hazardous waste to submit an annual report electronically through the RCRA Information (RCRAInfo) Waste Import and Export Tracking System (WIETS). The report lists the types, quantities, shipment frequency, and ultimate destination of all hazardous waste exported in 2026.

Take note! If an exporter doesn’t ship any hazardous waste after obtaining consent to export certain hazardous wastes, the exporter must still submit an annual report that lists the quantity shipped under the issued consent as 0.

2025 Greenhouse Gas (GHG) Annual Report

Due: March 10, 2027

The GHG Reporting Program (GHGRP) requires large industrial sources of GHG emissions, fuel and industrial gas suppliers, and carbon dioxide injection facilities to report GHG emissions from 2025 for all applicable source categories. Facilities submit reports through EPA’s Greenhouse Gas Reporting Tool (e-GGRT).

Take note! Annual GHG reports for the previous calendar year are usually due by March 31 of the next calendar year. However, EPA issued an interim final rule (effective October 14, 2026) extending the submission deadline for Reporting Year 2025 GHG reports to March 10, 2027.

Toxics Release Inventory (TRI) Report

Due: July 1, 2027

Section 313 of EPCRA requires facilities in specific industry sectors to submit a TRI Form R for each TRI-listed chemical (372.65) manufactured, processed, or otherwise used above threshold levels (listed at 372.25, 372.27, and 372.28) in the previous calendar year. The report, submitted through TRI-MEweb, covers waste management activities and any actions taken to reduce or prevent chemical waste during 2026.

Take note! TRI reports must be submitted to both EPA and the state. If your facility’s state participates in the TRI Data Exchange (TDX), TRI-MEweb will automatically send your report to the state. If your facility’s state doesn’t participate in TRI TDX, check the state’s TRI submission requirements to determine how to submit the required state copy.

Key to remember: The new year is quickly approaching, and the annual reporting compliance deadlines for many federal environmental programs are following closely behind.

EPA proposes major changes to oil, gas emission rules
2026-10-29T05:00:00Z

EPA proposes major changes to oil, gas emission rules

On October 29, 2026, EPA published a proposed rule to amend certain emission standards that were established by a rule finalized in 2024 (2024 Final Rule) for new and existing crude oil and natural gas facilities

Who’s impacted?

The proposed rule primarily applies to:

  • New, modified, and reconstructed crude oil and natural gas facilities subject to the New Source Performance Standards (NSPS) at 40 CFR Part 60 Subpart OOOOb; and
  • Existing crude oil and natural gas facilities subject to the emissions guidelines (EGs) at Part 60 Subpart OOOOc.

Collectively, these standards are known as the OOOOb/c rule.

What are the proposed changes?

EPA’s rule proposes revisions to a range of regulations established by the 2024 Final Rule.

Well site categories

The agency co-proposes two options for creating distinct categories of well sites, either:

  • By production level as marginal or non-marginal (with reduced requirements for marginal wells), or
  • By resource type as conventional or unconventional (with reduced requirements for conventional wells).

EPA also proposes an alternative approach to the marginal or non-marginal option, adding further sub-categories of marginal wells based on production levels.

Covers and closed vent systems (CVSs)

EPA proposes to divide the No Identifiable Emissions (NIE) standard into:

  • Design requirements, and
  • Operational requirements.

Additionally, the operational requirements would allow for repairs so that emissions that are fixed within a limited timeframe wouldn’t be a deviation.

Associated gas

EPA proposes to modify the best system of emission reduction (BSER) for associated gas from oil wells, including an approach that would allow routing associated gas to a control device or flare meeting specific emission-reduction requirements.

Control devices

The agency proposes to change control device requirements related to:

  • Continuous burning pilot flames,
  • Flame monitoring data deviations,
  • Control device alerts,
  • Visible emissions test conditions for fugitive emissions,
  • Temporary or backup control devices,
  • Temporary process controllers, and
  • Control device categories.

Other requirements

EPA addresses other aspects of the 2024 Final Rule, proposing to revise requirements for:

  • Liquids unloading,
  • Process controllers,
  • Pumps,
  • Fugitive emissions,
  • Storage vessels,
  • Covers and CVSs, and
  • Equipment leaks at gas plants.

Further, the proposed rule would allow gas processing facilities subject to the NSPS at Part 60 Subparts OOOO, OOOOa, and KKK to conduct optical gas imaging surveys according to Appendix K.

Super Emitter Program

EPA plans to rescind the Super Emitter Program that requires regulated sources to be monitored for methane leaks and releases above a specific threshold by certified third parties using remote-sensing technology. If the threshold is exceeded, it’s known as a “super-emitter event.” The third party notifies EPA, which then notifies a source that a super-emitter event has occurred at its facility. The source must find the leak or release, report its investigation results to EPA, and take corrective action if needed.

Note that the Super Emitter Program isn’t in effect. EPA’s July 2025 interim final rule delayed the program start date to January 22, 2027.

Key to remember: EPA proposes significant changes to emission standards for new and existing oil and natural gas facilities.

Wyoming updates noncoal surface mining regulations

Effective date: August 21, 2026

This applies to: Noncoal surface mining operations

Description of change: The Wyoming Land Quality Division (LQD) adopted a new chapter and amended three related chapters governing noncoal surface mining operation regulations.

The LQD added Noncoal Chapter 14 to set blasting requirements for noncoal surface mining operations, including requirements for blasting plans for operations that anticipate using explosives.

It also revised Noncoal Chapters 2, 9, and 10 to establish that other types of operations are subject to some or all of the blasting regulations established by Noncoal Chapter 14. For example, the following types of operations must develop blasting plans if the operations are expected to use blasting as part of the mining:

  • Regular noncoal mine permit applicants,
  • Small mining operations, and
  • Limited mining operations on 15 acres or less of affected land.
EPA updates formaldehyde testing standards for composite wood products
2026-10-29T05:00:00Z

EPA updates formaldehyde testing standards for composite wood products

EPA published a final rule on October 28, 2026, updating the formaldehyde emission standards for composite wood products under the Toxic Substances Control Act (TSCA). The rule provides a new quality control test method option and updates specific voluntary consensus standards incorporated by reference.

Who’s impacted?

The formaldehyde emission standards apply to entities that manufacture (including import), sell, supply, offer for sale, or certify certain composite wood products that use formaldehyde, including:

  • Hardwood plywood,
  • Medium-density fiberboard,
  • Particleboard, and
  • Products containing these composite wood materials.

It may also apply to entities that test these materials or work with certification firms that certify them.

Regulated entities use approved voluntary consensus standards to comply with the formaldehyde emission standards (40 CFR Part 770).

What are the changes?

EPA’s final rule updates six voluntary consensus standards incorporated by reference to the most current standards issued by the American National Standards Institute (ANSI), the American Society for Testing and Materials (ASTM), the International Organization for Standardization (ISO), and the National Institute of Standards and Technology (NIST). Regulated entities must comply with the updated versions of these standards.

The final rule also adds an allowable quality control testing method. ISO 12460-2:2024(en), “Wood-based panels — Determination of Formaldehyde Release — Part 2: Small-scale Chamber Method,” is a small-scale chamber test method for measuring formaldehyde emissions from wood products. The new standard contains a wider range of analytical methods that entities can use (e.g., laser absorption spectroscopy).

Finally, the rule removes the British Standards Institute BS EN ISO 12460-3:2020 standard from the allowable quality control methods since ISO 12460-3:2023(E), one of the existing standards that’s being updated by the final rule, is identical.

The final rule takes effect November 27, 2026.

Key to remember: EPA updated the formaldehyde testing standards for composite wood products, adding a quality control test method and updating multiple voluntary consensus standards.

Looking beyond PFAS: Emerging contaminants draw EPA's attention
2026-10-23T05:00:00Z

Looking beyond PFAS: Emerging contaminants draw EPA's attention

For years, conversations about emerging contaminants have focused on per- and polyfluoroalkyl substances (PFAS). While PFAS remain a major regulatory and public concern, they represent only one part of a much larger picture. Regulators and researchers are increasingly evaluating a broader range of chemicals that may be present in drinking water and the environment.

A recent EPA research initiative highlights this shift. In September 2026, EPA announced a scientific study that will use non-targeted analysis (NTA) to improve the agency's understanding of emerging contaminants in drinking water. Unlike traditional analytical methods that look for a limited list of chemicals, NTA allows researchers to screen for thousands of potential contaminants and identify previously unknown substances.

Emerging contaminants continue to evolve

There's no single regulatory definition of "emerging contaminant." Generally, the term refers to chemicals that have been detected in the environment and may present risks to human health or ecosystems but aren't yet fully understood, routinely monitored, or regulated.

Many emerging contaminants are not new chemicals. In many cases, they've been used for decades. What's changed is the ability to detect them at very low concentrations and to better understand where they occur, how they move through the environment, and what impacts they may have.

PFAS are a prime example. Once largely unknown outside technical circles, they're now the subject of drinking water standards, reporting requirements, cleanup efforts, and litigation. Other contaminant groups may follow a similar path as research continues.

EPA is expanding its view beyond PFAS

As part of its study, EPA developed a screening library containing more than 1,400 emerging contaminants. According to EPA, the library includes more than 1,000 pesticides and pesticide metabolites, more than 250 pharmaceuticals and personal care products, more than 70 PFAS, and other emerging contaminants.

While PFAS remain the most recognized emerging contaminant family, EPA's screening efforts extend far beyond fluorinated chemicals. The pharmaceutical and personal care product category includes compounds such as antibiotics, hormones, and other medicinal ingredients that can enter the environment through wastewater systems and other pathways. The pesticide category encompasses herbicide, insecticide, fungicide, and pesticide degradation products that may persist in soil, groundwater, or surface water.

EPA states that the study will help identify contaminants that may warrant additional investigation in the future.

Why this matters now

Most facilities aren't currently required to monitor for hundreds or thousands of emerging contaminants. However, today's research efforts often become tomorrow's regulatory priorities.

Historically, contaminants often attract scientific attention long before regulatory requirements follow. As occurrence data grows and analytical methods improve, regulators gain a better understanding of where contaminants are found and whether additional action is needed.

Facilities that manufacture, process, use, discharge, or dispose of chemicals should understand which substances are present in their operations and waste streams. This includes evaluating raw materials, wastewater discharges, byproducts, and residual wastes. Facilities may also want to monitor supplier communications and regulatory developments related to chemicals used in their operations.

Organizations with strong chemical inventory management and environmental review processes are often better positioned to adapt when new contaminants attract regulatory attention.

Preparing for what comes next

Organizations don't need to become experts on every emerging contaminant. However, focusing solely on PFAS could cause them to overlook broader trends developing across the environmental landscape.

EPA's latest drinking water study demonstrates that regulators are increasingly using advanced analytical tools to evaluate a much wider universe of chemicals. Whether the next major concern involves pharmaceuticals, pesticide metabolites, or another group of contaminants, facilities that stay informed about emerging issues will be better positioned to anticipate and respond to future compliance challenges.

Key to remember: PFAS may be the most visible emerging contaminant today, but they're unlikely to be the last. EPA's recent drinking water study shows that regulators are evaluating a much broader range of contaminants, making it important for facilities to stay informed about emerging chemical concerns before they become regulatory requirements.

Hawaii overhauls solid waste landfill regulations

Effective date: September 25, 2026

This applies to: Facilities that manage solid waste

Description of change: The State of Hawaii Department of Health made the first major update to the solid waste management control regulations in decades. The amended regulations:

  • Increase flexibility for small municipal solid waste landfills (MSWLFs),
  • Revise siting restrictions for MSWLFs,
  • Add requirements for construction and demolition landfills and special waste landfills,
  • Add leachate control and closure requirements for all solid waste management facilities,
  • Require auto processing and salvaging on an impervious surface, and
  • Update the solid waste permitting program.

Examples of significant changes include:

  • Adding requirements for facilities that manage solid waste (except landfills), such as leachate control for all facilities and use of impervious working surfaces for solid waste salvage facilities;
  • Updating MSWLF requirements (such as requiring compliance with the federal maximum contaminant level or state level (whichever is lower) for groundwater contaminants); and
  • Adding new requirements for construction and demolition landfills.

Description of change: The Ohio Environmental Protection Agency (EPA) adopted regulations for CCR generated by electric utilities and disposed of in dedicated landfills and surface impoundments. The new rules partially implement the federal CCR regulations (40 CFR Part 257 Subpart D). They also contain state-specific provisions (OAC Chapter 3745-525) for requirements related to CCR permits to install and financial assurance for landfills previously regulated by OAC Chapter 3745-30.

The Ohio EPA plans to apply for partial approval to implement the CCR program in place of EPA.

Texas adopts financial assurance rules for recycling facilities

Effective date: October 1, 2026

This applies to: Recycling facilities that accept, process, and repurpose renewable energy components

Description of change: The Texas Commission on Environmental Quality (TCEQ)’s final rule adds 30 TAC Chapter 376 (and amends Chapter 328 accordingly) to establish new requirements for recycling facilities that accept, process, and repurpose renewable energy components for recovering valuable materials from:

  • Wind turbine generators,
  • Solar energy devices, and
  • Battery energy storage systems.

The new rule adds reporting, financial assurance, and penalty requirements. For example, the regulation requires recycling facilities to submit annual reports by January 15 that include:

  • An inventory of unrecycled renewable energy components,
  • An estimated timeline to recycle them,
  • A cost estimate for recycling or disposing of the materials prepared by a third-party Texas-licensed professional engineer, and
  • Evidence of financial assurance for the cost estimate.

California amends vehicle regulations

Effective date: September 10, 2026

This applies to: Public agency utilities, high-priority fleets, and drayer trucks subject to the Advanced Clean Fleets (ACF) regulation and hydrogen refueling stations subject to the Low Carbon Fuel Standard (LCFS) regulation

Description of change: The California Air Resources Board (CARB) amended the ACF’s state and local government requirements. CARB’s final rule:

  • Extends the 50 percent zero-emission vehicle (ZEV) purchase requirement to January 1, 2030;
  • Modifies the Daily Usage Exemption and the ZEV Purchase Exemption to allow all vehicles of all model years to be eligible for consideration;
  • Adds an exemption under the ZEV Milestones Option for captive waste and wastewater fleets that produce biomethane on-site;
  • Expands the ZEV Purchase Exemption availability criteria to ensure minimum ZEV warranty requirements and manufacturer experience or reliability and streamlines the exemption process;
  • Modifies the Fleet Resiliency Exemption by lowering the ZEV penetration threshold from 25 to 5 percent of the fleet where it stays and expands eligibility to all vehicle types; and
  • Repeals sections of the ACF regulation for high-priority fleets and drayer trucks (these regulations were never implemented because CARB didn’t have a federal preemption waiver to enforce them).

CARB also amended the LCFS regulation, modifying the derating factors for light- and medium-duty hydrogen refueling infrastructure (LMD-HRI) crediting. CARB reduced the derating factor so that LMD-HRI stations may receive HRI credits for the full nameplate capacity for public stations and 50 percent of the nameplate capacity for private stations.

EPA proposes reallocating excess 2025 SREs to 2026, 2027
2026-10-20T05:00:00Z

EPA proposes reallocating excess 2025 SREs to 2026, 2027

On October 16, 2026, EPA published a rule proposing to revise the Small Refinery Exemption (SRE) reallocation volumes for compliance years 2026 and 2027 under the Renewable Fuel Standard (RFS) program.

Who’s impacted?

The RFS program applies to obligated parties, including:

  • Refiners of gasoline or diesel fuel (i.e., transportation fuel); and
  • Importers of transportation fuel.

EPA sets annual renewable fuel volume and percentage standards for each compliance year. Obligated parties must calculate their individual renewable volume obligations (RVOs), measured in Renewable Identification Numbers (RINs), and obtain and retire enough RINs to meet their RVOs for each compliance year.

What’s the issue?

In April 2026, EPA established the annual volume and percentage standards for the 2026 and 2027 compliance years (Set 2 Rule), including reallocating part of the SREs granted and expected to be granted for the 2023–2025 compliance years.

However, EPA granted a higher volume of SREs for the 2025 compliance year than expected, exempting 770 million more RINs than the Set 2 Rule projected for the 2026 and 2027 compliance years. The agency plans to revise the Set 2 Rule to account for the additional SRE reallocation volume.

What’s the proposed solution?

EPA proposes reallocating 100 percent of the additional 770 million RINs by reallocating the additional 2025 exempted RVO either:

  • Equally between the 2026 and 2027 compliance years, or
  • Fully to the 2027 compliance year.

The proposed rule would adjust the renewable volume and percentage standards for biomass-based diesel, advanced biofuel, and total renewable fuel. The Set 2 Rule didn’t establish SRE reallocation volumes for cellulosic biofuel.

Additionally, the proposed rule may extend the current 2026 compliance reporting deadline of March 31, 2027.

EPA will host a virtual public hearing for the proposed rule on November 4, 2026. Public comments on the rule are due by December 4, 2026 (Docket ID No. EPA-HQ-OAR-2024-0505).

Key to remember: EPA proposes to reallocate the excess 2025 small refinery exemption volumes to the 2026 and 2027 compliance years.

When one activity triggers multiple environmental obligations
2026-10-16T05:00:00Z

When one activity triggers multiple environmental obligations

Environmental compliance programs are often managed separately. Air permitting, hazardous waste, stormwater, emergency planning, and chemical reporting frequently involve different personnel, regulations, and procedures.

The challenge is that facilities don't operate that way. They operate processes, and those processes rarely fit neatly within a single regulatory category.

A company rarely decides to implement an "air program change" or a "hazardous waste change." Instead, it purchases a new solvent, installs a fuel tank, modifies a manufacturing process, or adds new equipment. A single operational decision can affect multiple environmental compliance programs at the same time. When organizations evaluate changes through only one regulatory lens, they risk overlooking obligations that arise elsewhere.

The following examples illustrate how one product, process, or activity can trigger requirements across several environmental programs.

Switching to a new paint or solvent

A facility may decide to replace an existing paint, coating, or solvent to improve product quality, address supply chain challenges, or reduce costs. Before making the switch, environmental professionals should consider how the change could affect multiple compliance obligations.

A new paint or solvent may contain a different concentration of volatile organic compounds (VOCs), affecting air emission calculations, permit applicability, or recordkeeping requirements. Spent materials, contaminated wipes, absorbents, and cleanup residues may require a new hazardous waste determination. Depending on the chemical composition and quantities involved, the material could also affect Tier II inventory reporting or Toxics Release Inventory (TRI) reporting obligations.

What appears to be a straightforward purchasing decision can ultimately affect air compliance, waste management, and chemical reporting programs.

Installing a diesel fuel storage tank

Organizations often add fuel storage to support emergency generators, fleet operations, or business continuity initiatives. While the project may be viewed primarily as an operational improvement, it can create environmental obligations in several areas.

The tank may count toward Spill Prevention, Control, and Countermeasure (SPCC) applicability thresholds. Fuel storage can also increase stormwater pollution risks, requiring updates to inspection procedures, pollution prevention controls, or employee training. Secondary containment requirements, spill response procedures, and release reporting obligations may also need review.

A project initially viewed as a facilities improvement may affect spill prevention, stormwater management, and emergency preparedness responsibilities.

Managing aerosol cans

Aerosol cans are commonly used throughout facilities for maintenance, cleaning, lubrication, painting, and other routine activities. Their widespread use can cause organizations to overlook their broader compliance implications.

Depending on how they're managed, discarded aerosol cans may qualify for the federal universal waste regulations. If cans are punctured and processed for recycling, facilities must also consider hazardous waste management requirements, employee training, and potential air emission concerns associated with puncturing operations. Likewise, storage practices, container management, and recordkeeping procedures should be evaluated.

Because aerosol cans intersect with waste management, recycling, and air concerns, they demonstrate how a routine maintenance activity can involve multiple regulatory programs.

Adding a refrigeration process

Expanding refrigerated storage capacity or installing a new industrial refrigeration process may seem like a project driven by production needs. However, depending on the refrigerant used and the quantity stored on-site, the environmental and safety implications can extend well beyond equipment installation.

Certain refrigerants may be subject to leak management and repair, servicing, recovery, and recordkeeping requirements. Depending on the substance and quantity stored on-site, facilities may also trigger Tier II or TRI reporting obligations.

For facilities using substances such as anhydrous ammonia, increasing refrigerant inventories may have even broader consequences. Exceeding regulatory thresholds could trigger EPA's Risk Management Program (RMP) requirements and OSHA's Process Safety Management (PSM) obligations, adding responsibilities related to process hazard analyses, operating procedures, employee training, emergency planning, mechanical integrity, and management of change.

The project may also require updates to emergency response procedures, hazard communication programs, and chemical inventory management processes. As a result, a decision driven by production or storage needs may affect environmental reporting, accident prevention, emergency preparedness, and process safety requirements across the facility.

Looking beyond program boundaries

Environmental regulations are often organized by media, program, or statute. Facilities, however, operate through products, equipment, and processes. Because of this difference in perspective, a single operational change can have consequences that reach far beyond its original purpose.

Organizations that routinely evaluate projects through multiple compliance lenses are often better positioned to identify environmental obligations before they become compliance issues. Asking how a new product, process, equipment installation, or operational change might affect air, waste, water, chemical reporting, spill prevention, emergency planning, or process safety requirements can help reduce surprises and support more effective compliance management.

Key to remember: Environmental compliance obligations rarely exist in isolation. Before implementing a new product, process, or operational change, consider how it may affect multiple environmental programs, not just the one most directly associated with the project.

Court vacates EPA’s methylene chloride rule: How should facilities respond?

Court vacates EPA’s methylene chloride rule: How should facilities respond?

When a court overturns an environmental regulation, it can be tempting to adopt an “all bets are off” approach and stop efforts to comply with the rule. However, facilities that continue to operate as if the rule still applies are better prepared to meet any future rulemaking that’s likely to occur. On September 15, 2026, the U.S. Court of Appeals for the Fifth Circuit vacated EPA’s methylene chloride risk management rule established under the Toxic Substances Control Act (TSCA) and remanded it back to the federal agency for further proceedings. EPA must restart the rulemaking process for methylene chloride.

Here’s what you need to know about the ruling and how your facility can respond to “hedge its bets” against future environmental regulations of methylene chloride.

What regulations and facilities are impacted?

The court’s decision in East Fork Enterprises, Inc. v. EPA (Case No. 24-60227) impacts EPA’s methylene chloride risk management rule finalized in May 2024 (2024 final rule). The rule applied to entities that manufacture (including import), process, distribute in commerce, use, or dispose of methylene chloride or methylene chloride-containing products.

Reasons for overturning the methylene chloride rule

The court listed a range of reasons for vacating the 2024 final rule, including the following significant findings.

Whole-chemical approach

EPA used a “whole chemical” approach in its revised 2022 risk determination for methylene chloride (on which the 2024 final rule is based) instead of making individual risk determinations for each condition of use (COU). As a result, EPA recharacterized six COUs (previously found not to present unreasonable risk) as posing unreasonable risk.

Court’s conclusion: TSCA doesn’t permit EPA to issue a whole-chemical risk determination; it requires EPA to evaluate and issue risk determinations for each COU.

Personal protective equipment (PPE) assumption

In its 2022 risk determination, EPA didn’t assume that exposed employees use PPE. However, TSCA requires the agency to account for PPE use if evidence suggests that it’s commonly used.

Court’s conclusion: There was sufficient evidence for EPA to assume PPE use, especially given that OSHA’s methylene chloride standard generally requires the use of PPE when employee exposure warrants it.

Risk analysis methods

EPA’s approach to “unreasonable risk” went beyond the statutory limits, appearing to attempt to eliminate nearly all risks. Further, EPA’s risk analysis didn’t comply with TSCA’s “best available science” standard (producing exposure limits unsupported by substantial evidence), and the agency overlooked relevant evidence.

Court’s conclusion: TSCA requires EPA to identify only unreasonable risk, which allows for some risk; the act isn’t designed to eliminate all risk. Also, TSCA mandates the agency to base its risk evaluations on all acceptable scientific information, including data contrary to its presuppositions.

Regulating to the extent necessary

EPA exceeded its authority by imposing regulations beyond “the extent necessary.” The court ruled that EPA’s basis for requiring a near-complete ban on methylene chloride use was unauthorized because it was based on the agency’s uncertainty as to whether a risk deemed reasonable will stay reasonable.

Court’s conclusion: TSCA permits EPA to eliminate actual, identified unreasonable risk. The agency can’t ban chemicals based on a reasonable risk that may become unreasonable in the future.

What’s next?

The court vacated with remand EPA’s methylene chloride rule and associated risk determination. As a result, EPA’s risk determination for methylene chloride is invalid, and the methylene chloride risk management rule is no longer in effect. Additionally, EPA must develop a new risk management rule that resolves the issues identified in the court’s opinion.

How should regulated entities respond?

EPA’s methylene chloride risk management rule is legally unenforceable, including its bans on uses and the regulatory requirements (such as the Workplace Chemical Protection Program). However, due to the uncertainty of EPA’s response and future rulemaking, companies should respond thoughtfully. Consider these tips:

  • Watch closely for EPA’s response to this litigation.
  • Consider maintaining protective measures and compliance programs that were implemented in response to the 2024 final rule, where possible. Continuing these efforts may ease compliance burdens if EPA issues a revised rule in the future. For example:
    • Continue conducting exposure monitoring and recording the results,
    • Keep searching for possible substitutes, and
    • Maintain workplace protections that are already implemented.
  • Ensure compliance with existing methylene chloride regulations, including:
    • EPA’s March 2019 final rule banning methylene chloride for consumer paint and coating removal, and
    • OSHA’s occupational exposure control requirements for methylene chloride (29 CFR 1910.1052).

Key to remember: A U.S. court vacated EPA’s 2024 methylene chloride risk management rule, but facilities that maintain protections and compliance programs developed under the rule may be better prepared for any future regulations of the chemical.

EPA proposes additional TCE compliance delays
2026-10-14T05:00:00Z

EPA proposes additional TCE compliance delays

On October 14, 2026, EPA published a proposed rule to extend additional compliance dates for the trichloroethylene (TCE) risk management rule finalized in 2024 (2024 TCE final rule) under the Toxic Substances Control Act (TSCA). If finalized, the rule would delay compliance deadlines for certain chemical processors and refrigerant manufacturers.

Who’s impacted?

The 2024 TCE final rule applies to entities that manufacture (including import), process, distribute in commerce, use, or dispose of TCE or TCE-containing products.

The proposed rule specifically affects:

  • Chemical processors;
  • Manufacturers, processors, and distributors subject to downstream notification requirements; and
  • Refrigerant manufacturers that process TCE to make HFC-134a.

What are the proposed changes?

For chemical processors, EPA proposes to move the prohibition compliance dates from December 18, 2026, to December 31, 2027, for:

  • Processing TCE as a reactant/intermediate;
  • Processing TCE for the industrial and commercial use of TCE as a processing aid in as well as the industrial and commercial use of TCE as a processing aid in:
    • Process solvent used in battery manufacturing;
    • Process solvent used in polymer fiber spinning, fluoroelastomer manufacturing, and Alcantara manufacturing;
    • Extraction solvent used in caprolactam manufacturing; and
    • Precipitant used in beta-cyclodextrin manufacturing.
  • Disposing of TCE through wastewater from such processing and uses to industrial pretreatment, industrial treatment, or publicly owned treatment works.

For manufacturers, processors, and distributors in commerce, the proposed rule amends the compliance date for downstream notifications and the text required to be in the Safety Data Sheets (SDSs) to reflect the new prohibition compliance dates. EPA would require affected manufacturers, processors, and distributors to update the SDSs with the new text 30 days after the publication date of a final rule.

For refrigerant manufacturers, EPA proposes extending the first phaseout reduction of processing TCE as an intermediate to manufacture HFC-134a. The 2024 TCE final rule requires manufacturers to reduce the annual amount of TCE feedstock they use to no greater than 75 percent of their baseline by June 7, 2027. This proposed rule would push the compliance date to December 31, 2027.

Key to remember: EPA proposes extending the TCE prohibition compliance deadline for certain chemical processors and the TCE feedstock phasedown date for specific refrigerant manufacturers.
