The Environmental Protection Agency (EPA) continues to add regulations to per- and polyfluoroalkyl substances (PFAS). The new rule finalized in January 2024 prevents facilities from using inactive PFAS before EPA reviews the planned use and makes a risk determination.
This significant new use rule (SNUR) applies to the 329 PFAS designated as inactive on the Toxic Substances Control Act (TSCA) Chemical Substance Inventory and aren’t yet subject to an existing SNUR. An inactive PFAS hasn’t been manufactured (including imported) or processed in the U.S. since June 21, 2006.
What are PFAS?
Also called “forever chemicals,” PFAS are a group of thousands of manufactured chemicals that are used widely in industry and consumer products. Many take a long time to break down and build up over time. They’re found nearly everywhere in water, air, soil, and consumer products, such as nonstick cookware, food packaging, clothing, and shampoo.
Some studies suggest that exposure to PFAS may lead to health issues. However, research continues since much remains unknown about the chemical substances. EPA regulates PFAS to prevent them from entering air, land, and water at levels that may harm human health and the environment.
What are the new SNUR requirements?
Under TSCA, EPA can determine that a certain use of a chemical substance is a “significant new use” and require anyone who wants to use the chemical substance for that purpose to first notify the agency. EPA will then conduct a review and risk determination. The new SNUR requires EPA to conduct reviews and risk determinations of the inactive PFAS before they can be used again.
If your facility wants to manufacture (including import) or process an inactive PFAS, notify EPA at least 90 days through a significant new use notice before beginning use. Once EPA receives the notification, the agency will:
If the new use doesn’t present an unreasonable risk and EPA makes an affirmative determination, your facility can use the PFAS. However, if the new use presents an unreasonable risk, the agency must first regulate the activity before you can use the PFAS.
What are other recent regulations of PFAS?
Over the past three years, EPA has implemented the 2021–2024 PFAS Strategic Roadmap, the agency's comprehensive strategy to address the risks of PFAS exposure and contamination through specific regulatory actions. The agency focuses on three directives: researching the forever chemicals, restricting the release of them into the environment, and cleaning up PFAS-contaminated sites.
This final rule joins EPA’s other actions taken via the PFAS Strategic Roadmap. These include:
How does this affect you?
If your facility manufactures (including imports) or processes PFAS, you’ll likely face more regulations and reporting requirements. So, how can you remain compliant? Stay informed of EPA’s latest regulatory actions regarding PFAS. Consider these best practices:
Also, consider the proactive approach to search for safer alternative chemicals you can substitute for PFAS. It’s vital to choose chemicals already reviewed by EPA to ensure the alternative option doesn’t also present an unreasonable risk to human health and the environment.
Key to remember: EPA continues to strengthen its regulation of PFAS. A new rule now prevents facilities from using any of the 300+ inactive PFAS before EPA conducts a risk determination and, if necessary, regulates the activity.

Hi everyone! Welcome to the monthly news roundup video, where we’ll go over the most impactful environmental, health, and safety news. Please view the content links in the transcript for more information about the topics I’ll be covering today. Let’s get started! The Office of Management and Budget completed its review of OSHA’s worker walkaround final rule on March 20. The next step is publication in the Federal Register. The rule expands the criteria for who employees can authorize to act as their representative during an OSHA inspection.
Stand Up 4 Grain Safety Week was held the week of March 25. This annual event brings attention to hazards in the grain handling and storage industry and encourages employers to focus on safe work practices.
Over 100 people die in ladder-related deaths each year, and thousands more suffer disabling injuries. During Ladder Safety Month, which is held each March, the American Ladder Institute promotes ladder safety to decrease the number of injuries and fatalities.
Between 2010 and 2023, 11 miners drowned in incidents involving submerged mobile equipment. In response, the Mine Safety and Health Administration issued a safety alert. It recommends measures miners should take when operating equipment near water.
And finally, turning to environmental news, EPA finalized amendments to its Risk Management Program in an effort to improve safety at facilities that use and distribute hazardous chemicals. The rule seeks to improve chemical process safety; assist in planning for, preparing for, and responding to accidents; and increase public awareness of chemical hazards at regulated sites.
Thanks for tuning in to the monthly news roundup. We’ll see you next month!
The Environmental Protection Agency (EPA) is promulgating new greenhouse gas (GHG) emissions standards for model year (MY) 2032 and later heavy-duty highway vehicles that phase in starting as early MY 2027 for certain vehicle categories. The phase in revises certain MY 2027 GHG standards that were established previously under EPA's Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles—Phase 2 rule (“HD GHG Phase 2”). This document also updates discrete elements of the Averaging Banking and Trading program, including providing additional flexibilities for manufacturers to support the implementation of the Phase 3 program balanced by limiting the availability of certain advanced technology credits initially established under the HD GHG Phase 2 rule. EPA is also adding warranty requirements for batteries and other components of zero-emission vehicles and requiring customer-facing battery state-of-health monitors for plug-in hybrid and battery electric vehicles. In this action, we are also finalizing additional revisions, including clarifying and editorial amendments to certain highway heavy-duty vehicle provisions and certain test procedures for heavy-duty engines.

The Environmental Protection Agency (EPA) finalized a rule to designate two widely used PFAS — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers — as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
The rule requires entities to immediately report releases of PFOA and PFOS that meet or exceed the reportable quantity (1 pound) to the:
Further, it gives EPA the authority to hold polluters responsible for paying for or conducting investigations and cleanup of PFOA and PFOS releases. In a memorandum, EPA clarified that it will focus enforcement efforts on significant contributors to PFAS releases.
Additionally:
The rule takes effect 60 days after it’s published in the Federal Register.
Key to remember: EPA has designated PFOA and PFOS as CERCLA hazardous substances, requiring immediate release notifications for the two PFAS and expanding the agency’s authority to hold parties responsible for contamination accountable.
It’s time for that special event that happens once every four years, often testing the endurance of the participants who’ve spent the prior years preparing for this very moment. No, it’s not the Summer Olympics, though that’s a great guess. It’s the Chemical Data Report!
Under the Toxic Substances Control ACT (TSCA), the Environmental Protection Agency’s (EPA’s) Chemical Data Reporting (CDR) rule requires manufacturers (including importers) to report information on the production and use of chemicals in commerce if they meet certain production volume thresholds at any one site. The submission period for the 2024 report runs from June 1 to September 30, 2024.
Use these tips to help you complete a Chemical Data Report worthy of a gold medal.
The TSCA Chemical Substance Inventory (TSCA Inventory) lists the covered chemical substances. Generally, the production volume threshold is 25,000 pounds or more of a chemical substance at a site. However, a reduced reporting threshold (2,500 pounds) applies to chemical substances subject to:
Further, certain full and partial exemptions apply to facilities based on the:
To confirm whether your facility must report:
The CDR rule requires facilities to report the total annual production volume of covered chemical substances for each calendar year since the last principal reporting year.
In other words, if a chemical substance at your facility meets or exceeds the corresponding reporting threshold during any calendar year covered by the report, you must include the total annual production volume of that chemical for every covered calendar year.
For example, you must list on the 2024 report the production volumes of every reportable chemical substance for 2020, 2021, 2022, and 2023.
All CDR data must be reported electronically on Form U (EPA Form 7740-8) through e-CDRweb on EPA’s Central Data Exchange (CDX) system. Reporting is site-specific, so if your organization has multiple sites with reportable chemicals, you must submit a Form U for each site.
Keep in mind that you submit only one form per site, so all reportable chemical substances at a specific site are listed on the same Form U. You may have to submit multiple forms only if you have more than one site covered by the CDR rule.
To submit a Chemical Data Report, you must first register with the CDX system and be approved by EPA. Plus, you must register the name of the organization on whose behalf you’re submitting a Form U. If you’re already registered on CDX, you can add the CDR reporting flow to your current registration.
Because each type of user role has varying permissions, it’s essential to register for the right one. User roles include:
Only Primary Authorized Officials may submit initial Chemical Data Reports. So, if you’re the one who will submit Form U, confirm that you’re registered as a Primary Authorized Official.
The CDR rule requires organizations to keep records of all CDR information reported on Form U to EPA for at least five years (711.25). The five-year timeline begins on the last day of the submission period.
Additionally, you may have to amend Form U after submitting the initial report. This can apply if:
Key to remember: The Chemical Data Report can be a major undertaking, but with these tips, you can cross the finish line with a report worthy of a gold medal.
Under the Clean Air Act, the Environmental Protection Agency (EPA) is establishing new, more protective emissions standards for criteria pollutants and greenhouse gases (GHG) for light-duty vehicles and Class 2b and 3 (‘‘medium-duty’’) vehicles that will phase-in over model years 2027 through 2032. In addition, EPA is finalizing GHG program revisions in several areas, including off-cycle and air conditioning credits, the treatment of upstream emissions associated with zero-emission vehicles and plug-in hybrid electric vehicles in compliance calculations, medium-duty vehicle incentive multipliers, and vehicle certification and compliance. EPA is also establishing new standards to control refueling emissions from incomplete medium-duty vehicles, and battery durability and warranty requirements for light-duty and medium-duty electric and plug-in hybrid electric vehicles. EPA is also finalizing minor amendments to update program requirements related to aftermarket fuel conversions, importing vehicles and engines, evaporative emission test procedures, and test fuel specifications for measuring fuel economy.

On August 31, 2020, in accordance with requirements under the Clean Air Act (CAA), the U.S. Environmental Protection Agency (EPA) performed a 5-year review of the Standards of Performance for New Stationary Sources and Emissions Guidelines for Existing Sources: Other Solid Waste Incineration (OSWI) Units, which includes certain very small municipal waste combustion (VSMWC) and institutional waste incineration (IWI) units. In the same action, the EPA proposed to remove the title V permitting requirements for air curtain incinerators (ACI) that burn only wood waste, clean lumber, yard waste, or a mixture of these three types of waste. In response to supportive comments received on the August 2020 proposal, this action is finalizing, as proposed, to remove the title V permitting requirements for ACIs that only burn wood waste, clean lumber, yard waste, or a mixture of those, and are not located at title V major sources or subject to title V for other reasons. The EPA is finalizing this proposed action now to simplify the compliance obligations for owners and operators of these types of units.
DATES: The effective date of this rule is April 17, 2024, published in the Federal Register April 17, 2024, page 27392.

§60.2966 Am I required to apply for and obtain a title V operating permit for my unit?
Yes, if you are subject to this subpart, you are required to apply for and obtain a title V operating permit unless you meet the relevant requirements for an exemption specified in §60.2887.
§60.2967 When must I submit a title V permit application for my new unit?
(a) If your new unit subject to this subpart is not subject to an earlier permit application deadline, a complete title V permit application must be submitted on or before one of the dates specified in paragraphs (a)(1) or (2) of this section. (See section 503(c) of the Clean Air Act and 40 CFR 70.5(a)(1)(i) and 40 CFR 71.5(a)(1)(i).)
(1) For a unit that commenced operation as a new source as of December 16, 2005, then a complete title V permit application must be submitted not later than December 18, 2006.
(2) For a unit that does not commence operation as a new source until after December 16, 2005, then a complete title V permit application must be submitted not later than 12 months after the date the unit commences operation as a new source.
(b) If your new unit subject to this subpart is subject to title V as a result of some triggering requirement(s) other than this subpart (for example, a unit subject to this subpart may be a major source or part of a major source), then your unit may be required to apply for a title V permit prior to the deadlines specified in paragraph (a) of this section. If more than one requirement triggers a source's obligation to apply for a title V permit, the 12-month timeframe for filing a title V permit application is triggered by the requirement that first causes the source to be subject to title V. (See section 503(c) of the Clean Air Act and 40 CFR 70.3(a) and (b), 40 CFR 70.5(a)(1)(i), 40 CFR 71.3(a) and (b), and 40 CFR 71.5(a)(1)(i).)
(c) A “complete” title V permit application is one that has been determined or deemed complete by the relevant permitting authority under section 503(d) of the Clean Air Act and 40 CFR 70.5(a)(2) or 40 CFR 71.5(a)(2). You must submit a complete permit application by the relevant application deadline in order to operate after this date in compliance with Federal law. (See sections 503(d) and 502(a) of the Clean Air Act and 40 CFR 70.7(b) and 40 CFR 71.7(b).)
Subpart FFFF - Emission Guidelines and Compliance Times for Other Solid Waste Incineration Units That Commenced Construction On or Before December 9, 2004
§60.3059 Am I required to apply for and obtain a title V operating permit for my unit?
Yes, if you are subject to an applicable EPA-approved and effective Clean Air Act section 111(d)/129 State or Tribal plan or an applicable and effective Federal plan, you are required to apply for and obtain a title V operating permit unless you meet the relevant requirements for an exemption specified in §60.2993.
The U.S. Environmental Protection Agency (EPA) is finalizing changes to its test procedures required to be used by industries and municipalities when analyzing the chemical, physical, and biological properties of wastewater and other samples for reporting under the EPA's National Pollutant Discharge Elimination System permit program. The Clean Water Act requires the EPA to promulgate these test procedures (analytical methods) for analysis of pollutants. The EPA anticipates that these changes will provide increased flexibility for the regulated community in meeting monitoring requirements while improving data quality. In addition, this update to the CWA methods will incorporate technological advances in analytical technology and make a series of minor changes and corrections to existing approved methods. As such, the EPA expects that these changes will not result in any negative economic impacts.

4 For the determination of total metals (which are equivalent to total recoverable metals) the sample is not filtered before processing. A digestion procedure is required to solubilize analytes in suspended material and to break down organic-metal complexes (to convert the analyte to a detectable form for colorimetric analysis). For non-platform graphite furnace atomic absorption determinations, a digestion using nitric acid (as specified in Section 4.1.3 of Methods for Chemical Analysis of Water and Wastes) is required prior to analysis. The procedure used should subject the sample to gentle acid refluxing, and at no time should the sample be taken to dryness. For direct aspiration flame atomic absorption (FLAA) determinations, a combination acid (nitric and hydrochloric acids) digestion is preferred, prior to analysis. The approved total recoverable digestion is described as Method 200.2 in Supplement I of “Methods for the Determination of Metals in Environmental Samples” EPA/600R-94/111, May 1994, and is reproduced in EPA Methods 200.7, 200.8, and 200.9 from the same Supplement. However, when using the gaseous hydride technique or for the determination of certain elements such as antimony, arsenic, selenium, silver, and tin by non-EPA graphite furnace atomic absorption methods, mercury by cold vapor atomic absorption, the noble metals and titanium by FLAA, a specific or modified sample digestion procedure may be required, and, in all cases the referenced method write-up should be consulted for specific instruction and/or cautions. For analyses using inductively coupled plasma-atomic emission spectrometry (ICP-AES), the direct current plasma (DCP) technique or EPA spectrochemical techniques (platform furnace AA, ICP-AES, and ICP-MS), use EPA Method 200.2 or an approved alternate procedure ( e.g., CEM microwave digestion, which may be used with certain analytes as indicated in this table IB); the total recoverable digestion procedures in EPA Methods 200.7, 200.8, and 200.9 may be used for those respective methods. Regardless of the digestion procedure, the results of the analysis after digestion procedure are reported as “total” metals. | |||||
5 Copper sulfate or other catalysts that have been found suitable may be used in place of mercuric sulfate. | |||||
6 Manual distillation is not required if comparability data on representative effluent samples are on file to show that this preliminary distillation step is not necessary; however, manual distillation will be required to resolve any controversies. In general, the analytical method should be consulted regarding the need for distillation. If the method is not clear, the laboratory may compare a minimum of 9 different sample matrices to evaluate the need for distillation. For each matrix, a matrix spike and matrix spike duplicate are analyzed both with and without the distillation step (for a total of 36 samples, assuming 9 matrices). If results are comparable, the laboratory may dispense with the distillation step for future analysis. Comparable is defined as <20% RPD for all tested matrices). Alternatively, the two populations of spike recovery percentages may be compared using a recognized statistical test. | |||||

12 Carbonaceous biochemical oxygen demand (CBOD 5) must not be confused with the traditional BOD 5 test method which measures “total 5-day BOD.” The addition of the nitrification inhibitor is not a procedural option but must be included to report the CBOD 5 parameter. A discharger whose permit requires reporting the traditional BOD 5 may not use a nitrification inhibitor in the procedure for reporting the results. Only when a discharger's permit specifically states CBOD 5 is required can the permittee report data using a nitrification inhibitor. | |||||

29 Approved methods for the analysis of silver in industrial wastewaters at concentrations of 1 mg/L and above are inadequate where silver exists as an inorganic halide. Silver halides such as the bromide and chloride are relatively insoluble in reagents such as nitric acid but are readily soluble in an aqueous buffer of sodium thiosulfate and sodium hydroxide to pH of 12. Therefore, for levels of silver above 1 mg/L, 20 mL of sample should be diluted to 100 mL by adding 40 mL each of 2 M Na 2 S 2 O 3 and NaOH. Standards should be prepared in the same manner. For levels of silver below 1 mg/L the approved method is satisfactory. | |||||
30 The use of EDTA decreases method sensitivity. Analysts may omit EDTA or replace with another suitable complexing reagent provided that all method-specified quality control acceptance criteria are met. | |||||
31 For samples known or suspected to contain high levels of silver ( e.g., in excess of 4 mg/L), cyanogen iodide should be used to keep the silver in solution for analysis. Prepare a cyanogen iodide solution by adding 4.0 mL of concentrated NH 4 OH, 6.5 g of KCN, and 5.0 mL of a 1.0 N solution of I 2 to 50 mL of reagent water in a volumetric flask and dilute to 100.0 mL. After digestion of the sample, adjust the pH of the digestate to <7 to prevent the formation of HCN under acidic conditions. Add 1 mL of the cyanogen iodide solution to the sample digestate and adjust the volume to 100 mL with reagent water (NOT acid). If cyanogen iodide is added to sample digestates, then silver standards must be prepared that contain cyanogen iodide as well. Prepare working standards by diluting a small volume of a silver stock solution with water and adjusting the pH>7 with NH 4 OH. Add 1 mL of the cyanogen iodide solution and let stand 1 hour. Transfer to a 100-mL volumetric flask and dilute to volume with water. | |||||

59 Samples analyzed for available cyanide using OI Analytical method OIA-1677-09 or ASTM method D6888-16 that contain particulate matter may be filtered only after the ligand exchange reagents have been added to the samples, because the ligand exchange process converts complexes containing available cyanide to free cyanide, which is not removed by filtration. Analysts are further cautioned to limit the time between the addition of the ligand exchange reagents and sample filtration to no more than 30 minutes to preclude settling of materials in samples. | |||||
60 Analysts should be aware that pH optima and chromophore absorption maxima might differ when phenol is replaced by a substituted phenol as the color reagent in Berthelot Reaction (“phenol-hypochlorite reaction”) colorimetric ammonium determination methods.

4 Method 624.1 may be used for quantitative determination of acrolein and acrylonitrile, provided that the laboratory has documentation to substantiate the ability to detect and quantify these analytes at levels necessary to comply with any associated regulations. In addition, the use of sample introduction techniques other than simple purge-and-trap may be required. QC acceptance criteria from Method 603 should be used when analyzing samples for acrolein and acrylonitrile in the absence of such criteria in Method 624.1. |
5 Method 625.1 may be extended to include benzidine, hexachlorocyclopentadiene, N-nitrosodimethylamine, N-nitrosodi- n -propylamine, and N-nitrosodiphenylamine. However, when they are known to be present, Methods 605, 607, and 612, or Method 1625B, are preferred methods for these compounds. Method 625.1 may be applied to 2,3,7,8-Tetrachloro-dibenzo- p -dioxin for screening purposes only. |

7 Each analyst must make an initial, one-time demonstration of their ability to generate acceptable precision and accuracy with Methods 601-603, 1624B, and 1625B in accordance with procedures in Section 8.2 of each of these methods. Additionally, each laboratory, on an on-going basis must spike and analyze 10% (5% for Methods 624.1 and 625.1 and 100% for methods 1624B and 1625B) of all samples to monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any parameter falls outside the quality control (QC) acceptance criteria in the pertinent method, analytical results for that parameter in the unspiked sample are suspect. The results should be reported but cannot be used to demonstrate regulatory compliance. If the method does not contain QC acceptance criteria, control limits of ±three standard deviations around the mean of a minimum of five replicate measurements must be used. These quality control requirements also apply to the Standard Methods, ASTM Methods, and other methods cited. |

7 Each analyst must make an initial, one-time, demonstration of their ability to generate acceptable precision and accuracy with Methods 608.3 and 625.1 in accordance with procedures given in Section 8.2 of each of these methods. Additionally, each laboratory, on an on-going basis, must spike and analyze 10% of all samples analyzed with Method 608.3 or 5% of all samples analyzed with Method 625.1 to monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any parameter falls outside the warning limits, the analytical results for that parameter in the unspiked sample are suspect. The results should be reported, but cannot be used to demonstrate regulatory compliance. These quality control requirements also apply to the Standard Methods, ASTM Methods, and other methods cited. |

5 Tests must be conducted to provide organism enumeration (density). Select the appropriate configuration of tubes/filtrations and dilutions/volumes to account for the quality, character, consistency, and anticipated organism density of the water sample. |
6 When the MF method has not been used previously to test waters with high turbidity, large numbers of noncoliform bacteria, or samples that may contain organisms stressed by chlorine, a parallel test should be conducted with a multiple-tube technique to demonstrate applicability and comparability of results. |
7 To assess the comparability of results obtained with individual methods, it is suggested that side-by-side tests be conducted across seasons of the year with the water samples routinely tested in accordance with the most current Standard Methods for the Examination of Water and Wastewater or EPA alternate test procedure (ATP) guidelines. |

10 The multiple-tube fermentation test is used in 9221B.3-2014. Lactose broth may be used in lieu of lauryl tryptose broth (LTB), if at least 25 parallel tests are conducted between this broth and LTB using the water samples normally tested, and this comparison demonstrates that the false-positive rate and false-negative rate for total coliform using lactose broth is less than 10 percent. No requirement exists to run the completed phase on 10 percent of all total coliform-positive tubes on a seasonal basis. |
11 These tests are collectively known as defined enzyme substrate tests. |
12 After prior enrichment in a presumptive medium for total coliform using 9221B.3-2014, all presumptive tubes or bottles showing any amount of gas, growth or acidity within 48 h ± 3 h of incubation shall be submitted to 9221F-2014. Commercially available EC-MUG media or EC media supplemented in the laboratory with 50 µg/mL of MUG may be used. |
13 Samples shall be enumerated by the multiple-tube or multiple-well procedure. Using multiple-tube procedures, employ an appropriate tube and dilution configuration of the sample as needed and report the Most Probable Number (MPN). Samples tested with Colilert® may be enumerated with the multiple-well procedures, Quanti-Tray® or Quanti-Tray®/2000, and the MPN calculated from the table provided by the manufacturer. |
14 Colilert-18® is an optimized formulation of the Colilert® for the determination of total coliforms and E. coli that provides results within 18 h of incubation at 35 °C, rather than the 24 h required for the Colilert® test and is recommended for marine water samples. |

5 ASTM D7365-09a (15) specifies treatment options for samples containing oxidants (e.g ., chlorine) for cyanide analyses. Also, Section 9060A of Standard Methods for the Examination of Water and Wastewater (23rd edition) addresses dechlorination procedures for microbiological analyses.
EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs). The chemical substances received “not likely to present an unreasonable risk” determinations pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance.

This action finalizes the residual risk and technology review (RTR) conducted for the Commercial Sterilization Facilities source category regulated under national emission standards for hazardous air pollutants (NESHAP) under the Clean Air Act. The EPA is finalizing decisions concerning the RTR, including definitions for affected sources, emission standards for previously unregulated sources, amendments pursuant to the risk review to address ethylene oxide (EtO) emissions from certain sterilization chamber vents (SCVs), aeration room vents (ARVs), chamber exhaust vents (CEVs), and room air emissions, and amendments pursuant to the technology review for certain SCVs and ARVs. In addition, we are taking final action to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including removing exemptions for periods of SSM. We are also taking final action to require owners and operators to demonstrate compliance through the use of EtO continuous emissions monitoring systems (CEMS), with exceptions for very small users of EtO; add provisions for electronic reporting of performance test results and other reports; and include other technical revisions to improve consistency and clarity. We estimate that these final amendments will reduce EtO emissions from this source category by approximately 21 tons per year (tpy).
DATES: This final rule is effective on April 5, 2024, published in the Federal Register April 5, 2024, page 24090.

“What’s the worst that could happen?” You’ve likely heard and have even asked this rhetorical question. Under the Clean Water Act (CWA), it’s no longer rhetorical; it’s now a regulatory question that must be answered with formal, written plans by facilities that could discharge dangerous chemicals into nearby waterbodies.
The Environmental Protection Agency (EPA) finalized a rule (codified at 40 CFR Part 118) that requires certain facilities to develop and submit Facility Response Plans (FRPs) for worst-case discharges or the potential for worst-case discharges of CWA hazardous substances into navigable water.
Use this article to help you determine whether your facility is covered by the CWA hazardous substance FRP requirements.
The final rule covers “onshore, non-transportation-related facilities that could reasonably be expected to cause substantial harm to the environment by discharging a CWA hazardous substance into or on the navigable waters, adjoining shorelines, or exclusive economic zone.” As with all other regulations, the definitions of the terms determine what the rules mean and what they require.
A facility considered to pose substantial harm must meet three conditions. The CWA hazardous substance FRP requirements apply to facilities that:
The final rule requires facilities to model worst-case discharge scenarios that represent each covered CWA hazardous substance. Through these scenarios, facilities determine whether they meet the first three substantial harm criteria above.
Determine whether your facility qualifies for any exceptions or exemptions to the FRP requirements listed at 118.8.
Exceptions include:
Exemptions apply to:
If your facility meets the applicability criteria and doesn’t qualify for any exceptions or exemptions, it’s subject to the CWA hazardous substance FRP requirements. You must prepare, submit to EPA, and implement an FRP.
Covered facilities must submit FRPs to EPA within three years of May 28, 2024 (the effective date of the rule).
Key to remember: A final rule under the Clean Water Act requires certain facilities to develop, submit to EPA, and implement Facility Response Plans for worst-case discharges of hazardous substances into navigable waters.
On July 6, 2020, the U.S. Environmental Protection Agency (EPA or the Agency) finalized the residual risk and technology review (RTR) conducted for the Ethylene Production source category, which is part of the Generic Maximum Achievable Control Technology Standards National Emission Standards for Hazardous Air Pollutants (NESHAP); on July 7, 2020, the EPA finalized the RTR conducted for the Organic Liquids Distribution (Non-Gasoline) NESHAP; and on August 12, 2020, the EPA finalized the RTR conducted for the Miscellaneous Organic Chemical Manufacturing NESHAP. Amendments to the Petroleum Refinery Sector NESHAP were most recently finalized on February 4, 2020. Subsequently, the EPA received and granted various petitions for reconsideration on these NESHAP for, among other things, the provisions related to the work practice standards for pressure relief devices (PRDs), emergency flaring, and degassing of floating roof storage vessels. This action finalizes proposed amendments to remove the force majeure exemption for PRDs and emergency flaring, incorporate clarifications for the degassing requirements for floating roof storage vessels, and address other corrections and clarifications.
DATES: This final action is effective on April 4, 2024, published in the Federal Register April 4, 2024, page 23840.

§63.641 Definitions.
* * * *
Flare means a combustion device lacking an enclosed combustion chamber that uses an uncontrolled volume of ambient air to burn gases. For the purposes of this rule, the definition of flare includes, but is not necessarily limited to, air-assisted flares, steam-assisted flares and non-assisted flares.
§63.643 Miscellaneous process vent provisions.
* * * *
(c)(1) Prior to venting to the atmosphere, process liquids are removed from the equipment as much as practical and the equipment is depressured to a control device meeting requirements in paragraphs (a)(1) or (2) of this section, a fuel gas system, or back to the process until one of the following conditions, as applicable, is met.
(i) The vapor in the equipment served by the maintenance vent has a lower explosive limit (LEL) of less than 10 percent.
(ii) If there is no ability to measure the LEL of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the LEL of the vapors in the maintenance vent (or inside the equipment if the maintenance is a hatch or similar type of opening) is less than 10 percent.
(iii) The equipment served by the maintenance vent contains less than 72 pounds of total volatile organic compounds (VOC).
(iv) If the maintenance vent is associated with equipment containing pyrophoric catalyst (e.g., hydrotreaters and hydrocrackers) and a pure hydrogen supply is not available at the equipment at the time of the startup, shutdown, maintenance, or inspection activity, the LEL of the vapor in the equipment must be less than 20 percent, except for one event per year not to exceed 35 percent.
(v) If, after applying best practices to isolate and purge equipment served by a maintenance vent, none of the applicable criterion in paragraphs (c)(1)(i) through (iv) of this section can be met prior to installing or removing a blind flange or similar equipment blind, the pressure in the equipment served by the maintenance vent is reduced to 2 psig or less. Active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.
(c)(2) Except for maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, the owner or operator must determine the LEL or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.
§63.648 Equipment leak standards.
* * * *
(j)(3)(iv) The owner or operator shall determine the total number of release events occurred during the calendar year for each affected pressure relief device separately. The owner or operator shall also determine the total number of release events for each pressure relief device for which the root cause analysis concluded that the root cause was a force majeure event, as defined in this subpart.
* * * *
(j)(3)(v)(B) A second release event not including force majeure events from a single pressure relief device in a 3 calendar year period for the same root cause for the same equipment.
(j)(3)(v)(C) A third release event not including force majeure events from a single pressure relief device in a 3 calendar year period for any reason.
* * * *
(j)(6) Root cause analysis and corrective action analysis. A root cause analysis and corrective action analysis must be completed as soon as possible, but no later than 45 days after a release event. Special circumstances affecting the number of root cause analyses and/or corrective action analyses are provided in paragraphs (j)(6)(i) through (iv) of this section.
* * * *
(j)(6)(ii) You may conduct a single root cause analysis and corrective action analysis for a single emergency event that causes two or more pressure relief devices to release, regardless of the equipment served, if the root cause is reasonably expected to be a force majeure event, as defined in this subpart.

§63.670 Requirements for flare control devices.
* * * *
(b) Pilot flame presence. The owner or operator shall operate each flare with a pilot flame present at all times when regulated material is routed to the flare. Each 15-minute block during which there is at least one minute where no pilot flame is present when regulated material is routed to the flare is a deviation of the standard. Deviations in different 15-minute blocks from the same event are considered separate deviations. The owner or operator shall monitor for the presence of a pilot flame as specified in paragraph (g) of this section.
* * * *
(d) Flare tip velocity. For each flare, the owner or operator shall comply with either paragraph (d)(1) or (2) of this section, provided the appropriate monitoring systems are in-place, whenever regulated material is routed to the flare for at least 15-minutes and the flare vent gas flow rate is less than the smokeless design capacity of the flare.
* * * *
(e) Combustion zone operating limits. For each flare, the owner or operator shall operate the flare to maintain the net heating value of flare combustion zone gas (NHVcz) at or above 270 British thermal units per standard cubic feet (Btu/scf) determined on a 15-minute block period basis when regulated material is routed to the flare for at least 15-minutes. The owner or operator shall monitor and calculate NHVcz as specified in paragraph (m) of this section.
* * * *
(5) When a continuous monitoring system is used as provided in paragraph (j)(1) or (3) of this section and, if applicable, paragraph (j)(4) of this section, the owner or operator may elect to determine the 15-minute block average NHVvg using either the calculation methods in paragraph (l)(5)(i) of this section or the calculation methods in paragraph (l)(5)(ii) of this section. The owner or operator may choose to comply using the calculation methods in paragraph (l)(5)(i) of this section for some flares at the petroleum refinery and comply using the calculation methods (l)(5)(ii) of this section for other flares. However, for each flare, the owner or operator must elect one calculation method that will apply at all times, and use that method for all continuously monitored flare vent streams associated with that flare. If the owner or operator intends to change the calculation method that applies to a flare, the owner or operator must notify the Administrator 30 days in advance of such a change.
(i) Feed-forward calculation method. When calculating NHVvg for a specific 15-minute block:
(A) Use the results from the first sample collected during an event, (for periodic flare vent gas flow events) for the first 15-minute block associated with that event.
(B) If the results from the first sample collected during an event (for periodic flare vent gas flow events) are not available until after the second 15-minute block starts, use the results from the first sample collected during an event for the second 15-minute block associated with that event.
(C) For all other cases, use the results that are available from the most recent sample prior to the 15-minute block period for that 15-minute block period for all flare vent gas steams. For the purpose of this requirement, use the time that the results become available rather than the time the sample was collected. For example, if a sample is collected at 12:25 a.m. and the analysis is completed at 12:38 a.m., the results are available at 12:38 a.m. and these results would be used to determine compliance during the 15-minute block period from 12:45 a.m. to 1:00 a.m.
(ii) Direct calculation method. When calculating NHVvg for a specific 15-minute block:
(A) If the results from the first sample collected during an event (for periodic flare vent gas flow events) are not available until after the second 15-minute block starts, use the results from the first sample collected during an event for the first 15-minute block associated with that event.
(B) For all other cases, use the arithmetic average of all NHVvg measurement data results that become available during a 15-minute block to calculate the 15-minute block average for that period. For the purpose of this requirement, use the time that the results become available rather than the time the sample was collected. For example, if a sample is collected at 12:25 a.m. and the analysis is completed at 12:38 a.m., the results are available at 12:38 a.m. and these results would be used to determine compliance during the 15-minute block period from 12:30 a.m. to 12:45 a.m.
* * * *
(o)(4)(iv) You may conduct a single root cause analysis and corrective action analysis for a single event that causes two or more flares to have a flow event meeting the criteria in paragraph (o)(3)(i) or (ii) of this section, regardless of the configuration of the flares, if the root cause is reasonably expected to be a force majeure event, as defined in this subpart.
* * * *
(o)(6) The owner or operator shall determine the total number of events for which a root cause and corrective action analyses was required during the calendar year for each affected flare separately for events meeting the criteria in paragraph (o)(3)(i) of this section and those meeting the criteria in paragraph (o)(3)(ii) of this section. For the purpose of this requirement, a single root cause analysis conducted for an event that met both of the criteria in paragraphs (o)(3)(i) and (ii) of this section would be counted as an event under each of the separate criteria counts for that flare. Additionally, if a single root cause analysis was conducted for an event that caused multiple flares to meet the criteria in paragraph (o)(3)(i) or (ii) of this section, that event would count as an event for each of the flares for each criteria in paragraph (o)(3) of this section that was met during that event. The owner or operator shall also determine the total number of events for which a root cause and correct action analyses was required and the analyses concluded that the root cause was a force majeure event, as defined in this subpart.
* * * *
(o)(7)(ii) Two visible emissions exceedance events meeting the criteria in paragraph (o)(3)(i) of this section that were not caused by a force majeure event from a single flare in a 3 calendar year period for the same root cause for the same equipment.
(iii) Two flare tip velocity exceedance events meeting the criteria in paragraph (o)(3)(ii) of this section that were not caused by a force majeure event from a single flare in a 3 calendar year period for the same root cause for the same equipment.
(iv) Three visible emissions exceedance events meeting the criteria in paragraph (o)(3)(i) of this section that were not caused by a force majeure event from a single flare in a 3 calendar year period for any reason.
(v) Three flare tip velocity exceedance events meeting the criteria in paragraph (o)(3)(ii) of this section that were not caused by a force majeure event from a single flare in a 3 calendar year period for any reason.
§63.671 Requirements for flare monitoring systems.

Waste stream means the waste generated by a particular process unit, product tank, or waste management unit. The characteristics of the waste stream (e.g., flow rate, HAP concentration, water content) are determined at the point of waste generation. Examples of a waste stream include process wastewater, product tank drawdown, sludge and slop oil removed from waste management units, and landfill leachate.
(3) Requirements. The owner or operator must control organic HAP emissions from each affected source emission point by meeting the applicable requirements specified in Table 7 to this section. An owner or operator must perform the applicability assessment procedures and methods for process vents specified in §63.1104, except for paragraphs (d), (g), (h) through (j), (l)(1), and (n). An owner or operator must perform the applicability assessment procedures and methods for equipment leaks specified in §63.1107. General compliance, recordkeeping, and reporting requirements are specified in §§63.1108 through 63.1112. Before July 6, 2023, minimization of emissions from startup, shutdown, and malfunctions must be addressed in the startup, shutdown, and malfunction plan required by §63.1111; the plan must also establish reporting and recordkeeping of such events. A startup, shutdown, and malfunction plan is not required on and after July 6, 2023 and the requirements specified in §63.1111 no longer apply; however, for historical compliance purposes, a copy of the plan must be retained and available on-site for five years after July 6, 2023. Except as specified in paragraph (e)(4)(i) of this section, procedures for approval of alternate means of emission limitations are specified in §63.1113.
(4) Flares. Beginning no later than the compliance dates specified in §63.1102(c), if a steam-assisted, air-assisted, non-assisted, or pressure-assisted multi-point flare is used as a control device for an emission point subject to the requirements in Table 7 to this section, then the owner or operator must meet the applicable requirements for flares as specified in §§63.670 and 63.671 of subpart CC, including the provisions in Tables 12 and 13 to subpart CC of this part, except as specified in paragraphs (e)(4)(i) through (xiv) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from an ethylene production unit, being used to control an emission point subject to the requirements in Table 7 of this section. For purposes of compliance with this paragraph, the following terms are defined in §63.641 of subpart CC: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.
(i) The owner or operator may elect to comply with the alternative means of emissions limitation requirements specified in of §63.670(r) of subpart CC in lieu of the requirements in §63.670(d) through (f) of subpart CC, as applicable. However, instead of complying with §63.670(r)(3) of subpart CC, the owner or operator must submit the alternative means of emissions limitation request following the requirements in §63.1113.
(ii) Instead of complying with §63.670(o)(2)(i) of subpart CC, the owner or operator must develop and implement the flare management plan no later than the compliance dates specified in §63.1102(c).
(iii) Instead of complying with §63.670(o)(2)(iii) of subpart CC, if required to develop a flare management plan and submit it to the Administrator, then the owner or operator must also submit all versions of the plan in portable document format (PDF) to the EPA via the Compliance and Emissions Data Reporting Interface (CEDRI), which can be accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). If you claim some of the information in your flare management plan is confidential business information (CBI), submit a version with the CBI omitted via CEDRI. A complete plan, including information claimed to be CBI and clearly marked as CBI, must be mailed to the following address: U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, Sector Policies and Programs Division, U.S. EPA Mailroom (E143-01), Attention: Ethylene Production Sector Lead, 109 T.W. Alexander Drive, Research Triangle Park, NC 27711.
(iv) Section 63.670(o)(3)(ii) of subpart CC and all references to §63.670(o)(3)(ii) of subpart CC do not apply. Instead, the owner or operator must comply with the maximum flare tip velocity operating limit at all times.
(v) Substitute “ethylene production unit” for each occurrence of “petroleum refinery.”
(vi) Each occurrence of “refinery” does not apply.
(vii) Except as specified in paragraph (e)(4)(vii)(G) of this section, if a pressure-assisted multi-point flare is used as a control device for an emission point subject to the requirements in Table 7 to this section, then the owner or operator must comply with the requirements specified in paragraphs (e)(4)(vii)(A) through (F) of this section.
(A) The owner or operator is not required to comply with the flare tip velocity requirements in §63.670(d) and (k) of subpart CC;

(C) The owner or operator must determine the 15-minute block average NHVvg using only the direct calculation method specified in §63.670(l)(5)(ii) of subpart CC;
(D) Instead of complying with §63.670(b) and (g) of subpart CC, if a pressure-assisted multi-point flare uses cross-lighting on a stage of burners rather than having an individual pilot flame on each burner, the owner or operator must operate each stage of the pressure-assisted multi-point flare with a flame present at all times when regulated material is routed to that stage of burners. Each stage of burners that cross-lights in the pressure-assisted multi-point flare must have at least two pilots with at least one continuously lit and capable of igniting all regulated material that is routed to that stage of burners. Each 15-minute block during which there is at least one minute where no pilot flame is present on a stage of burners when regulated material is routed to that stage is a deviation of the standard. Deviations in different 15-minute blocks from the same event are considered separate deviations. The pilot flame(s) on each stage of burners that use cross-lighting must be continuously monitored by a thermocouple or any other equivalent device used to detect the presence of a flame;
(E) Unless the owner or operator of a pressure-assisted multi-point flare chooses to conduct a cross-light performance demonstration as specified in this paragraph, the owner or operator must ensure that if a stage of burners on the flare uses cross-lighting, that the distance between any two burners in series on that stage is no more than 6 feet when measured from the center of one burner to the next burner. A distance greater than 6 feet between any two burners in series may be used provided the owner or operator conducts a performance demonstration that confirms the pressure-assisted multi-point flare will cross-light a minimum of three burners and the spacing between the burners and location of the pilot flame must be representative of the projected installation. The compliance demonstration must be approved by the permitting authority and a copy of this approval must be maintained onsite. The compliance demonstration report must include: A protocol describing the test methodology used, associated test method QA/QC parameters, the waste gas composition and NHVcz of the gas tested, the velocity of the waste gas tested, the pressure-assisted multi-point flare burner tip pressure, the time, length, and duration of the test, records of whether a successful cross-light was observed over all of the burners and the length of time it took for the burners to cross-light, records of maintaining a stable flame after a successful cross-light and the duration for which this was observed, records of any smoking events during the cross-light, waste gas temperature, meteorological conditions (e.g., ambient temperature, barometric pressure, wind speed and direction, and relative humidity), and whether there were any observed flare flameouts; and
(F) The owner or operator of a pressure-assisted multi-point flare must install and operate pressure monitor(s) on the main flare header, as well as a valve position indicator monitoring system for each staging valve to ensure that the flare operates within the proper range of conditions as specified by the manufacturer. The pressure monitor must meet the requirements in Table 13 to subpart CC of this part.
(G) If a pressure-assisted multi-point flare is operating under the requirements of an approved alternative means of emission limitations, the owner or operator shall either continue to comply with the terms of the alternative means of emission limitations or comply with the provisions in paragraphs (e)(4)(vii)(A) through (F) of this section.
(viii) If an owner or operator chooses to determine compositional analysis for net heating value with a continuous process mass spectrometer, the owner or operator must comply with the requirements specified in paragraphs (e)(4)(viii)(A) through (G) of this section.
(A) The owner or operator must meet the requirements in §63.671(e)(2). The owner or operator may augment the minimum list of calibration gas components found in §63.671(e)(2) with compounds found during a pre-survey or known to be in the gas through process knowledge.
(B) Calibration gas cylinders must be certified to an accuracy of 2 percent and traceable to National Institute of Standards and Technology (NIST) standards.
(C) For unknown gas components that have similar analytical mass fragments to calibration compounds, the owner or operator may report the unknowns as an increase in the overlapped calibration gas compound. For unknown compounds that produce mass fragments that do not overlap calibration compounds, the owner or operator may use the response factor for the nearest molecular weight hydrocarbon in the calibration mix to quantify the unknown component's NHVvg.
(D) The owner or operator may use the response factor for n-pentane to quantify any unknown components detected with a higher molecular weight than n-pentane.
(E) The owner or operator must perform an initial calibration to identify mass fragment overlap and response factors for the target compounds.
(F) The owner or operator must meet applicable requirements in Performance Specification 9 of 40 CFR part 60, appendix B, for continuous monitoring system acceptance including, but not limited to, performing an initial multi-point calibration check at three concentrations following the procedure in Section 10.1 and performing the periodic calibration requirements listed for gas chromatographs in Table 13 to subpart CC of this part, for the process mass spectrometer. The owner or operator may use the alternative sampling line temperature allowed under Net Heating Value by Gas Chromatograph in Table 13 to subpart CC of this part.
(G) The average instrument calibration error (CE) for each calibration compound at any calibration concentration must not differ by more than 10 percent from the certified cylinder gas value. The CE for each component in the calibration blend must be calculated using the following equation:
Where:
Cm = Average instrument response (ppm)
Ca = Certified cylinder gas value (ppm)
(ix) An owner or operator using a gas chromatograph or mass spectrometer for compositional analysis for net heating value may choose to use the CE of NHVmeasured versus the cylinder tag value NHV as the measure of agreement for daily calibration and quarterly audits in lieu of determining the compound-specific CE. The CE for NHV at any calibration level must not differ by more than 10 percent from the certified cylinder gas value. The CE for must be calculated using the following equation:
Where:
NHVmeasured = Average instrument response (Btu/scf)
NHVa = Certified cylinder gas value (Btu/scf)
(x) Instead of complying with §63.670(p) of subpart CC, the owner or operator must keep the flare monitoring records specified in §63.1109(e).
(xi) Instead of complying with §63.670(q) of subpart CC, the owner or operator must comply with the reporting requirements specified in §63.1110(d) and (e)(4).
(xii) When determining compliance with the pilot flame requirements specified in §63.670(b) and (g), substitute “pilot flame or flare flame” for each occurrence of “pilot flame.”
(xiii) When determining compliance with the flare tip velocity and combustion zone operating limits specified in §63.670(d) and (e), the requirement effectively applies starting with the 15-minute block that includes a full 15 minutes of the flaring event. The owner or operator is required to demonstrate compliance with the velocity and NHVcz requirements starting with the block that contains the fifteenth minute of a flaring event. The owner or operator is not required to demonstrate compliance for the previous 15-minute block in which the event started and contained only a fraction of flow.
(xiv) In lieu of meeting the requirements in §§63.670 and 63.671 of subpart CC, an owner or operator may submit a request to the Administrator for approval of an alternative test method in accordance with §63.7(f). The alternative test method must be able to demonstrate on an ongoing basis at least once every 15-minutes that the flare meets 96.5% combustion efficiency and provide a description of the alternative recordkeeping and reporting that would be associated with the alternative test method. The alternative test method request may also include a request to use the alternative test method in lieu of the pilot or flare flame monitoring requirements of 63.670(g).
(5) Maintenance vents. Unless an extension is requested in accordance with the provisions in §63.6(i) of subpart A, beginning no later than the compliance dates specified in §63.1102(c), an owner or operator may designate an ethylene process vent as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. The owner or operator must comply with the applicable requirements in paragraphs (e)(5)(i) through (iii) of this section for each maintenance vent.
(i) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements specified in paragraph (e)(4) of this section, or a non-flare control device meeting the requirements specified in §63.982(c)(2) of subpart SS, until one of the following conditions, as applicable, is met.
(A) The vapor in the equipment served by the maintenance vent has a lower explosive limit (LEL) of less than 10 percent.
(B) If there is no ability to measure the LEL of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the LEL of the vapors in the maintenance vent (or inside the equipment if the maintenance is a hatch or similar type of opening) is less than 10 percent.
(C) The equipment served by the maintenance vent contains less than 50 pounds of total volatile organic compounds (VOC).
(D) If, after applying best practices to isolate and purge equipment served by a maintenance vent, none of the applicable criterion in paragraphs (e)(5)(i)(A) through (C) of this section can be met prior to installing or removing a blind flange or similar equipment blind, then the pressure in the equipment served by the maintenance vent must be reduced to 2 psig or less before installing or removing the equipment blind. During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.
(ii) Except for maintenance vents complying with the alternative in paragraph (e)(5)(i)(C) of this section, the owner or operator must determine the LEL or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.
(iii) For maintenance vents complying with the alternative in paragraph (e)(5)(i)(C) of this section, the owner or operator must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.
(6) Bypass lines. Beginning on the compliance dates specified in §63.1102(c), the use of a bypass line at any time on a closed vent system to divert emissions subject to the requirements in Table 7 to §63.1103(e) to the atmosphere or to a control device not meeting the requirements specified in Table 7 of this subpart is an emissions standards violation. If the owner or operator is subject to the bypass monitoring requirements of §63.983(a)(3) of subpart SS, then the owner or operator must continue to comply with the requirements in §63.983(a)(3) of subpart SS and the recordkeeping and reporting requirements in §§63.998(d)(1)(ii) and 63.999(c)(2) of subpart SS, in addition to paragraph (e)(9) of this section, the recordkeeping requirements specified in §63.1109(g), and the reporting requirements specified in §63.1110(e)(6). For purposes of compliance with this paragraph, the phrase “Except for equipment needed for safety purposes such as pressure relief devices, low leg drains, high point bleeds, analyzer vents, and open-ended valves or lines” in §63.983(a)(3) does not apply; instead, the exemptions specified in paragraph (e)(6)(i) and (ii) of this section apply.
(i) Except for pressure relief devices subject to 40 CFR 63.1107(h)(4), equipment such as low leg drains and equipment subject to the requirements specified in paragraph (f) of Table 7 to §63.1103(e) are not subject to this paragraph (e)(6) of this section.
(ii) Open-ended valves or lines that use a cap, blind flange, plug, or second valve and follow the requirements specified in §60.482-6(a)(2), (b), and (c) or follow requirements codified in another regulation that are the same as §60.482-6(a)(2), (b), and (c) are not subject to this paragraph (e)(6) of this section.
(7) Decoking operation standards for ethylene cracking furnaces. Beginning no later than the compliance dates specified in §63.1102(c), the owner or operator must comply with paragraph (e)(7)(i) of this section and also use at least two of the control measures specified in paragraphs (e)(7)(ii) through (v) of this section to minimize coke combustion emissions from the decoking of the radiant tube(s) in each ethylene cracking furnace.
(i) During normal operations, conduct daily inspections of the firebox burners and repair all burners that are impinging on the radiant tube(s) as soon as practical, but not later than 1 calendar day after the flame impingement is found. The owner or operator may delay burner repair beyond 1 calendar day using the procedures specified in paragraphs (e)(7)(i)(A) and (B) of this section provided the repair cannot be completed during normal operations, the burner cannot be shutdown without significantly impacting the furnace heat distribution and firing rate, and action is taken to reduce flame impingement as much as possible during continued operation. An inspection may include, but is not limited to: visual inspection of the radiant tube(s) for localized bright spots (this may be confirmed with a temperature gun), use of luminescent powders injected into the burner to illuminate the flame pattern, or identifying continued localized coke build-up that causes short runtimes between decoking cycles. A repair may include, but is not limited to: Taking the burner out of service, replacing the burner, adjusting the alignment of the burner, adjusting burner configuration, making burner air corrections, repairing a malfunction of the fuel liquid removal equipment, or adding insulation around the radiant tube(s).
(A) If a shutdown for repair would cause greater emissions than the potential emissions from delaying repair, repair must be completed following the next planned decoking operation (and before returning the ethylene cracking furnace back to normal operations) or during the next ethylene cracking furnace complete shutdown (when the ethylene cracking furnace firebox is taken completely off-line), whichever is earlier.
(B) If a shutdown for repair would cause lower emissions than the potential emissions from delaying repair, then shutdown of the ethylene cracking furnace must immediately commence and the repair must be completed before returning the ethylene cracking furnace back to normal operations.
(ii) During decoking operations, beginning before the expected end of the air-in decoke time, continuously monitor (or use a gas detection tube or equivalent sample technique every three hours to monitor) the CO2 concentration in the combined decoke effluent downstream of the last component being decoked for an indication that the coke combustion in the ethylene cracking furnace radiant tube(s) is complete. The owner or operator must immediately initiate procedures to stop the coke combustion once the CO2 concentration at the outlet consistently reaches a level that indicates combustion of coke is complete and site decoke completion assurance procedures have been concluded.
(iii) During decoking operations, continuously monitor the temperature at the radiant tube(s) outlet when air is being introduced to ensure the coke combustion occurring inside the radiant tube(s) is not so aggressive (i.e., too hot) that it damages either the radiant tube(s) or ethylene cracking furnace isolation valve(s). The owner or operator must immediately initiate procedures to reduce the temperature at the radiant tube(s) outlet once the temperature reaches a level that indicates combustion of coke inside the radiant tube(s) is too aggressive.
(iv) After decoking, but before returning the ethylene cracking furnace back to normal operations, verify that decoke air is no longer being added.
(v) After decoking, but before returning the ethylene cracking furnace back to normal operations and/or during normal operations, inject materials into the steam or feed to reduce coke formation inside the radiant tube(s) during normal operation.
(8) Ethylene cracking furnace isolation valve inspections. Beginning no later than the compliance dates specified in §63.1102(c), the owner or operator must conduct ethylene cracking furnace isolation valve inspections as specified in paragraphs (e)(8)(i) and (ii) of this section.
(i) Prior to decoking operation, inspect the applicable ethylene cracking furnace isolation valve(s) to confirm that the radiant tube(s) being decoked is completely isolated from the ethylene production process so that no emissions generated from decoking operations are sent to the ethylene production process. If poor isolation is identified, then the owner or operator must rectify the isolation issue prior to continuing decoking operations to prevent leaks into the ethylene production process.
(ii) Prior to returning the ethylene cracking furnace to normal operations after a decoking operation, inspect the applicable ethylene cracking furnace isolation valve(s) to confirm that the radiant tube(s) that was decoked is completely isolated from the decoking pot or furnace firebox such that no emissions are sent from the radiant tube(s) to the decoking pot or furnace firebox once the ethylene cracking furnace returns to normal operation. If poor isolation is identified, then the owner or operator must rectify the isolation issue prior to continuing normal operations to prevent product from escaping to the atmosphere through the decoking pot or furnace firebox.
(9) Startup, shutdown, and malfunction referenced provisions. Beginning no later than the compliance dates specified in §63.1102(c), the referenced provisions specified in paragraphs (e)(9)(i) through (xx) of this section do not apply when demonstrating compliance with paragraph (e)(3) of this section.

§63.2550 What definitions apply to this subpart?
* * * *
In ethylene oxide service means the following:
(1) For equipment leaks, any equipment that contains or contacts a fluid (liquid or gas) that is at least 0.1 percent by weight of ethylene oxide. If information exists that suggests ethylene oxide could be present in equipment, the equipment is considered to be "in ethylene oxide service" unless sampling and analysis is performed as specified in §63.2492 to demonstrate that the equipment does not meet the definition of being "in ethylene oxide service". Examples of information that could suggest ethylene oxide could be present in equipment, include calculations based on safety data sheets, material balances, process stoichiometry, or previous test results provided the results are still relevant to the current operating conditions.
(2) For process vents, each batch and continuous process vent in a process that, when uncontrolled, contains a concentration of greater than or equal to 1 ppmv undiluted ethylene oxide, and when combined, the sum of all these process vents would emit uncontrolled ethylene oxide emissions greater than or equal to 5 lb/yr (2.27 kg/yr). If information exists that suggests ethylene oxide could be present in a batch or continuous process vent, then the batch or continuous process vent is considered to be "in ethylene oxide service" unless an analysis is performed as specified in §63.2492 to demonstrate that the batch or continuous process vent does not meet the definition of being "in ethylene oxide service". Examples of information that could suggest ethylene oxide could be present in a batch or continuous process vent, include calculations based on safety data sheets, material balances, process stoichiometry, or previous test results provided the results are still relevant to the current operating conditions.
(3) For storage tanks, storage tanks of any capacity and vapor pressure storing a liquid that is at least 0.1 percent by weight of ethylene oxide. If knowledge exists that suggests ethylene oxide could be present in a storage tank, then the storage tank is considered to be "in ethylene oxide service" unless sampling and analysis is performed as specified in §63.2492 to demonstrate that the storage tank does not meet the definition of being "in ethylene oxide service". The exemptions for "vessels storing organic liquids that contain HAP only as impurities" and "pressure vessels designed to operate in excess of 204.9 kilopascals and without emissions to the atmosphere" listed in the definition of "storage tank" in this section do not apply for storage tanks that may be in ethylene oxide service. Examples of information that could suggest ethylene oxide could be present in a storage tank, include calculations based on safety data sheets, material balances, process stoichiometry, or previous test results provided the results are still relevant to the current operating conditions.

To inform this consideration, EPA is requesting comment and information from all stakeholders on the use and exposure to lead from the manufacture (including importing), processing (including recycling), distribution in commerce, use, and disposal of lead wheel weights, as well as information on their substitutes, to help determine if there is unreasonable risk to human health and the environment associated with this use. This action is relevant to a petition for a writ of mandamus filed in August 2023, by the Ecology Center, Center for Environmental Health, United Parents Against Lead & Other Environmental Hazards, and Sierra Club in the United States Court of Appeals for the Ninth Circuit requesting the court to direct EPA to conduct a rulemaking regulating lead wheel weights under TSCA.
DATES: Comments must be received on or before May 3, 2024, published in the Federal Register April 3, 2024, page 22972.

(k) For large bells on each blast furnace, you must conduct visible emissions testing on the interbell relief valve according to EPA Method 22 in appendix A-7 to part 60 of this chapter, unless specified in paragraphs (k)(1) through (3) of this section. Testing must be conducted monthly, for 15 minutes.
(1) If visible emissions are detected for a large bell during the monthly visible emissions testing, you must conduct EPA Method 9 (in appendix A-4 to part 60 of this chapter) opacity tests in place of EPA Method 22 testing on that bell once per month, taking 3-minute averages for 15 minutes, until the large bell seal is repaired or replaced.
(2) If the average of 3 instantaneous visible emission readings taken while the interbell relief valve is exhausting exceeds 20 percent, you must initiate corrective action within five business days.
(3) Ten business days after the initial opacity exceedance of 20 percent, you must conduct an EPA Method 9 opacity test, taking 3-minute averages for 15 minutes. If the average of 3 instantaneous visible emissions readings from this test exceeds 20 percent, you must repair or replace that bell seal within 4 months.
(l) For small bells on each blast furnace, you must conduct visible emissions testing according to EPA Method 22 in appendix A-7 to part 60 of this chapter. Testing must be conducted monthly for 15 minutes. If visible emissions are observed, you must compare the period between the visible emissions being present and the most recent bell seal repair or replacement. If this time period or throughput is shorter or lower than the period or throughput stated in the O&M plan required by 63.7800, this new shorter period or lower limit shall be placed in the O&M plan as the work practice limit.

Representative conditions exclude periods of startup and shutdown. You shall not conduct performance tests during periods of malfunction. You must record the process information that is necessary to document operating conditions during the test and include in such record an explanation to support that such conditions represent normal operation. Upon request, you shall make available to the Administrator such records as may be necessary to determine the conditions of performance tests.
* * * *
§63.7825 What test methods and other procedures must I use to demonstrate initial compliance with the emission limits for hazardous air pollutants?
(a) If demonstrating compliance with the emission limits in Table 1 to this subpart through performance testing, you must conduct a performance test to demonstrate initial compliance with the emission limit. If demonstrating compliance with the emission limit through performance testing, you must conduct each performance test that applies to your affected source based on representative performance ( i.e., performance based on normal operating conditions) of the affected source for the period being tested, according to the conditions detailed in paragraphs (b) through (k) of this section. Representative conditions exclude periods of startup and shutdown. You shall not conduct performance tests during periods of malfunction. Initial compliance tests must be conducted by the deadlines in §63.7820(e).
* * * * *
(b) * * *
(1) * * *
(v) EPA Method 29 or 30B in appendix A-8 to part 60 of this chapter to determine the concentration of mercury from the exhaust stream stack of each unit. If performing measurements using EPA Method 29, you must collect a minimum sample volume of 1.7 dscm (60 dscf). Alternative test methods may be considered on a case-by-case basis per §63.7(f).
(2) Three valid test runs are needed to comprise a performance test of each unit in table 1 to this subpart as applicable. If the performance testing results for any of the emission points yields a non-detect value, then the method detection limit (MDL) must be used to calculate the mass emissions (lb) for that emission unit and, in turn, for calculating the sum of the emissions (in units of pounds of mercury per ton of steel scrap or pounds of mercury per ton of product sinter) for all units subject to the emission standard for determining compliance. If the resulting mercury emissions are greater than the MACT emission standard, the owner or operator may use procedures that produce lower MDL results and repeat the mercury performance testing one additional time for any emission point for which the measured result was below the MDL. If this additional testing is performed, the results from that testing must be used to determine compliance ( i.e., there are no additional opportunities allowed to lower the MDL).
* * * * *
(c) Calculate the mass emissions, based on the average of three test run values, for each BOPF Group unit (or combination of units that are ducted to a common stack and are tested when all affected sources are operating pursuant to paragraph (a) of this section) using equation 1 to this paragraph (c) as follows:
Where:
E = Mass emissions of pollutant, pounds (lb);
C s = Concentration of pollutant in stack gas, mg/dscm;
454,000 = Conversion factor (mg/lb);
Q = Volumetric flow rate of stack gas, dscf/min;
35.31 = Conversion factor (dscf/dscm); and
t = Duration of test, minutes.
* * * *
§63.7830 What are my monitoring requirements?
* * * *
(e)(2) Compute and record the 30-day rolling average of the volatile organic compound emissions (lbs/ton of sinter) for each operating day using the procedures in §63.7824(e).
§63.7841 What reports must I submit and when?
* * * *
(d) CEDRI submission. If you are required to submit reports following the procedure specified in this paragraph, you must submit reports to the EPA via CEDRI, which can be accessed through EPA's CDX ( https://cdx.epa.gov/ ). You must use the appropriate electronic report template on the CEDRI website ( https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri ) for this subpart. The date report templates become available will be listed on the CEDRI website. The report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted. Do not use CEDRI to submit information you claim as CBI. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim for some of the information in the report, you must submit a complete file, including information claimed to be CBI, to the EPA following the procedures in paragraphs (d)(1) and (2) of this section. Clearly mark the part or all of the informatioqn that you claim to be CBI. Information not marked as CBI may be authorized for public release without prior notice. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the EPA is required to make emissions data available to the public. Thus, emissions data will not be protected as CBI and will be made publicly available. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph.
(1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address oaqpscbi@epa.gov, and as described above, should include clear CBI markings and be flagged to the attention of the Integrated Iron and Steel Sector Lead. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email oaqpscbi@epa.gov to request a file transfer link.
(2) If you cannot transmit the file electronically, you may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, Research Triangle Park, North Carolina 27711, Attention Integrated Iron and Steel Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.
§63.7842 What records must I keep?
* * * *
(d) You must keep the records required in §§63.7823, 63.7833, and 63.7834 to show continuous compliance with each emission limitation and operation and maintenance requirement that applies to you. This includes a record of each large and small bell repair and replacement, a record of the date on which the large bell opacity has exceeded 20 percent, and the most current time period or throughput over which no opacity was observed from the small bell.

Climate change is no longer an impending threat. It is here and it has tangible consequences. As industry professionals, we understand the scientific basis for climate change and its anticipated effects.
However, translating this knowledge into actionable strategies requires robust risk planning. A recent survey conducted by the J. J. Keller Center for Market Insights revealed that only 20 percent of facilities currently engage in risk planning related to climate change.

Several factors impact how and why a business plans for environmental risk.
Business continuity: The domino effect of climate disruption
Among facilities currently engaged in risk planning for climate change, 65 percent consider business continuity. Extreme weather events are becoming more frequent and severe due to climate change. Floods, droughts, wildfires, and heat waves can disrupt critical infrastructure, transportation networks, and power grids. This can have a cascading effect, impacting a company's ability to operate and deliver products or services.
Proactive risk planning involves identifying vulnerabilities in your operations — from reliance on suppliers in one area to outdated infrastructure vulnerable to flooding. By conducting vulnerability assessments and developing contingency plans, businesses can ensure a smoother transition during climate disruptions, minimizing downtime and financial losses.
Brand image and reputation: The price of inaction
More than ever before, consumers are holding organizations responsible for their environmental impact. Failure to act on climate change can significantly hurt an organization's brand image and reputation. Ignoring climate risks suggests a lack of foresight and responsibility, potentially leading to boycotts, negative press coverage, and difficulty attracting employees.
Conversely, demonstrating proactive risk planning by implementing sustainable practices and adapting to climate change can enhance a company's brand image. It can translate to increased customer support, greater investor trust, and an edge in the marketplace.
Physical damage to facilities and assets: Counting the cost of climate
Among facilities currently engaging in risk planning for climate change, 59 percent consider physical damage. Climate change is a physical threat to businesses, with increased and often extreme geological and meteorological events posing a risk to facilities and assets. Rising sea levels threaten coastal locations, while extreme weather events can damage infrastructure and equipment.
Risk planning helps identify these exposures and develops strategies to mitigate them, such as elevating critical infrastructure, investing in flood-protection measures, or expanding production facilities across different geographic areas. By proactively addressing physical risks, businesses can minimize the financial burden of repairs and potential reconstruction efforts.
Regulatory risk and noncompliance costs: Staying ahead of the curve
Governments are progressively implementing regulations to address climate change. These regulations may include stricter environmental standards for production processes and mandatory reporting of greenhouse gas emissions. Businesses that fail to adapt their operations to comply with necessary regulations risk hefty fines and legal penalties.
Risk planning involves staying informed about evolving regulations and developing a strategy for compliance. This can help businesses easily adapt and avoid costly fines or even operational shutdowns.
Revenue loss: The bottom line of climate change
Climate change can negatively impact an organization's revenue stream in several ways. For example, droughts and floods can disrupt farming operations and supply chains, leading to shortages and price increases that can discourage customers. Severe weather events can damage attractions and infrastructure, impacting the tourism and hospitality industries. Additionally, regulations intended to address climate change, such as carbon taxing, can impact production costs, potentially leading to price increases and reduced end user demand. Risk planning helps businesses identify these potential losses and create approaches to mitigate them. Examples include investing in climate-smart agriculture, developing drought-resistant crops, or exploring alternative production methods that are less susceptible to climate disruptions.
Key to remember: Climate change is a complex challenge. Risk planning can help businesses protect their operations, reputation, and financial well-being.
The U.S. Environmental Protection Agency (EPA or Agency) is finalizing facility response plan requirements for worst case discharges of Clean Water Act (CWA) hazardous substances for onshore non-transportation-related facilities that could reasonably be expected to cause substantial harm to the environment by discharging a CWA hazardous substance into or on the navigable waters, adjoining shorelines, or exclusive economic zone.

An EPA final rule to designate two PFAS as hazardous substances under CERCLA is expected this year! However, a recent “standing-room-only” Senate hearing evaluated potential consequences of the rule. Much of the discussion was over liability concerns for “passive receivers” like water utilities and landfills. The upcoming rule may not provide EPA with flexibility to exempt them.
During the March 20 hearing, Senator Tom Carper (D-DE), Chairperson of the Senate Environment and Public Works Committee, made it a point that PFAS has proved useful. It has even saved many lives as a firefighting foam, he asserted. PFAS is short for per- and polyfluoroalkyl substances.
It’s also a pervasive threat to human health, Carper concluded. A health advocate who testified at the hearing warned the Senators that failing to address PFAS in drinking water will result in thousands of deaths. Cause-of-death examples he said include cancer, cardiovascular disease, and infant low birth weights.
Carper also brought up the millions of dollars to cleanup PFAS. He said it costs only $50 to $1,000 per pound to manufacture PFAS products. Yet, it costs $3M to $18M per pound to remove the compounds from wastewater, the lawmaker remarked. Testimony suggested that legal defense costs and technology investments can also add up to several million dollars for a facility.
Everyone at the hearing agreed that EPA has never “directly” listed a substance as a CERCLA substance under 40 CFR 302. CERCLA is the Comprehensive Environmental Response, Compensation, and Liability Act.
Looking back, EPA has always defined CERCLA hazardous substances that were first regulated by other laws, like the Clean Water Act (CWA) or the Resource Conservation and Recovery Act (RCRA). In this case, PFAS compounds would be declared CERCLA hazardous substances. However, that would be without regulation under another law. This is called “CERCLA first.”
That means, for example, there are no federal water or waste permits for PFAS (yet) that could provide an exemption (or liability shield) from CERCLA. Moreover, CERCLA is retroactive. So, even if PFAS is covered by later permits, parties may be responsible for PFAS released to water, air, or land before the issuance of a permit.
The Cabinet Secretary for the New Mexico Environment Department testified that he favors listing discarded PFAS as a RCRA hazardous waste first.
Carper stated that he has heard mounting concerns about the potential unintended impacts of the impending designation rule. Specifically, he mentioned entities that do not use these chemicals. The lawmaker explained that they could be held responsible for downstream PFAS contamination simply because the contamination traveled through their facility.
Senator and Ranking Member Shelley Capito (R-WV) agreed. “If an entity meets the definition of a ‘potentially responsible party,’ that entity is liable for all cleanup costs, regardless of intent or exercise of due care ... These entities are known as ‘passive receivers.” [They] did not manufacture or generate PFAS and were unknowingly, or required by law, to catch or to receive these contaminants.”
A legal expert for the Congressional Research Service revealed that under the upcoming rule, “Entities that have been involved in releases of PFAS could be held liable if the other preconditions to liability are met and no exemptions apply.” Her examples included:
Some testified that EPA has promised to focus enforcement efforts on PFAS manufacturers and industries that release significant amounts of PFAS. However, someone clarified that EPA would not be bound by this policy. Plus, states, tribes, and private parties can still bring litigation. A landfill association representative added, “If EPA chooses not to take any action, the passive receiver has no protection from a suit brought by another potentially responsible party.”
Both Carper and Capito say they’re looking for a bipartisan legislative response to the concerns. Legislative options might include:
Congress could also go the other way. It could direct EPA to designate various PFAS as hazardous substances under CERCLA.
A recent Senate hearing on PFAS went over liability and a possible liability shield for passive receivers like water utilities and landfills.
Each year, spring ushers in the season for green — budding trees, blooming plants, and the Greenhouse Gas Reporting Program (GHGRP). Okay, so the last item isn’t typically associated with thoughts of springtime. However, the March 31 deadline for the annual GHGRP report always springs up.
The GHGRP requires covered facilities, suppliers, and sites to submit an annual report of greenhouse gas (GHG) emissions data and other relevant information from the previous calendar year to the Environmental Protection Agency (EPA).
Although the reporting years change, the best practices for submitting accurate and timely reports don’t. Use the following checklist to help you comply with the GHG annual report requirements.
The GHGRP generally applies to:
See 40 CFR 98.2 for the complete eligibility requirements that facilities, suppliers, and CO2 injectors must meet to be subject to the GHG annual reporting requirements.
The GHGRP groups reporters by specific industry types known as source categories. Each facility must report GHG emissions for all source categories that apply.
The subparts under Part 98 list the requirements for each source category, such as:
For example, Part 98 Subpart Q lists the reporting requirements for the Iron and Steel Production category, while Part 98 Subpart MM lists the requirements for the Suppliers of Petroleum Products category.
Tables A-3, A-4, and A-5 under Part 98 Subpart A list the source categories and any specific reporting thresholds.
Reporters must use specific methodologies established in the regulations to determine GHG emissions from each source category. The subparts under Part 98 contain the approved calculation methodologies for each source category and generally include several options.
If you meet the method’s requirements, you can change emission calculation methods from year to year and within the same year.
A designated representative is the individual responsible for submitting the GHG reports on behalf of the owners and operators of the facility or supplier. The regulations at 98.4 allow (but don’t require) the designated representative to appoint an alternate designated representative and one or more agents who can act on their behalf.
EPA will not accept annual GHG emissions reports from a facility or supplier without a Certificate of Representation for a designated representative. This certificate must be submitted at least 60 days before the initial annual GHG emissions report deadline.
The GHG annual report is submitted electronically through EPA’s electronic Greenhouse Gas Reporting Tool (e-GGRT). To submit the annual report, you must first register as an e-GGRT user and create an account. If you already have an active EPA Central Data Exchange (CDX) account, log into e-GGRT with your existing CDX username and password. If you don’t have a CDX account or cannot log in with those credentials, create a new user account on e-GGRT.
All e-GGRT users must have the Electronic Signature Agreement (ESA) on file with EPA. You can electronically sign the agreement or submit a signed hard copy. Once EPA approves the agreement, the agency will send you an account activation notice, and you can begin registering a facility and the designated representative.
The designated representative must register as an e-GGRT user and, once EPA approves the representative’s ESA, accept the appointment as the designated representative and electronically sign the Certificate of Representation. The certificate allows the representative to certify, sign, and submit the annual GHG report to EPA. Resubmission of the certificate is required only when there are updates to the facility profile or information about the designated representative changes (including replacing the existing representative).
Key to remember: Annual reports for the Greenhouse Gas Reporting Program are due by March 31 and require reporters to include emissions data from all applicable source categories.
Quick action using cardiopulmonary resuscitation (CPR) and automated external defibrillators(AEDs) can save the lives of the nearly 350,000 cardiac event victims each year outside of a hospital setting. But what does OSHA require for the workplace? What you didn’t know about OSHA regulations regarding AEDs may surprise you.
For every minute a patient is in cardiac arrest, their chances of survival decrease dramatically. When a patient doesn’t have a pulse and isn’t breathing, CPR should be performed until an AED is available. It’s important to note that CPR alone does not restart the heart. CPR is an oxygen circulation procedure. AEDs, on the other hand, are meant for lifesaving intervention.
CPR and early defibrillation are vital components of the emergency medical services (EMS) chain of survival that increases the odds of cardiac patient survival. However, according to the American Heart Association (AHA), even the best CPR can’t provide enough circulation of oxygen to the brain and heart for more than a few minutes. In fact, a patient whose brain is deprived of oxygen for 10 minutes or more seldom recovers.
Just like a reliable vehicle, the circulatory system is the human body’s blood transportation system, and the heart is the engine. Amazingly, the heart generates its own electrical impulses, pumping in a regular, rhythmic manner. As with any engine, the heart requires a certain amount of pressure to function and doesn’t work well when clogged with grease or debris. The most common causes of sudden cardiac arrest include a heart attack, electrocution, and asphyxiation — all of which could occur in the workplace. Common signs and symptoms include:
CPR provides the pressure for the body’s “engine” to oxygen circulating, while an AED provides the electrical impulses to keep the engine pumping.
OSHA 1910.151 requires first aid treatment be provided in the absence of an infirmary, clinic, or hospital in near proximity to the workplace used to treat injured employees. This may include assisting a victim of cardiac arrest using CPR or defibrillation.
OSHA requirements for CPR and defibrillation differ considerably. Standards requiring CPR include:
OSHA recommends basic adult CPR refresher training and retesting every year, and first aid training at least once every three years. CPR training include facilitated discussion along with ’hands-on’ skills training that uses mannequins and partner practice.
Though OSHA recognizes AEDs as important lifesaving technology that plays a role in treating cardiac arrest, the agency doesn’t currently require their use in the workplace. Instead, OSHA wants employers to assess their own requirements for AEDs as part of their first aid response.
AEDs are considered Class III medical devices which means the Food and Drug Administration (FDA) has some oversight on their use. Almost all AEDs require the purchaser to obtain a prescription from a physician under FDA regulations. The prescription process is meant as a quality control mechanism to ensure AEDs are properly maintained, that all designated responders are properly trained, and assist employers with establishing an emergency response plan for their workplace AED program.
The AHA requires AED operators to also receive CPR training as an “integral part of providing lifesaving aid to people suffering sudden cardiac arrest.” Though easy to use, each AED is slightly different, so training helps users understand the unique traits and supplies for the individual units at their workplace. Additionally, AED users must be trained to understand the signs of a sudden cardiac arrest, when to activate the EMS system, and how to perform CPR.
AEDs are light, portable, easy to use, and inexpensive. They’re best placed near high-hazard areas such as confined spaces, near electrical energy, or in remote work areas. Response time to reach AEDs should be kept within 3–5-minutes.
Need more information on defibrillators in the workplace? See our ezExplanation on AEDs. |
Many states require or encourage CPR and AED training from nationally recognized organizations. Any AED training should include CPR training. OSHA doesn’t offer first aid or CPR training, nor certify trainers. Training by a nationally recognized organization, such as AHA, the American Red Cross, or National Safety Council is recommended.
While OSHA doesn’t currently require the use of AEDs in the workplace, they do expect employers to assess their own AED requirements as part of their first aid response. AED training is required by most states and should include CPR with a hands-on practical component.
OSHA requires employers to provide all workers with immediately available and sanitary restroom or toilet facilities. But does this include truckers and delivery drivers that stop at your facilities? The sanitation standards (1910.141, 1926.51, and 1928.110) are meant to protect all workers from adverse health effects from unsanitary toilets facilities, or the unavailability of facilities when needed.
Bipartisan legislation has recently been introduced in the House that would require businesses to provide restroom access to truckers who are loading or delivering cargo at their warehouses, manufacturers, distribution centers, retailers, and ports.
Supported by leading organizations in the trucking industry, the Trucker Bathroom Access Act (H.R. 9592) was introduced on Dec. 15, 2022. The bill requires retailers, warehouses, and other establishments with existing restrooms to provide access to drivers who are loading or delivering cargo. Additionally, operators of ports and marine terminals must provide access for drayage and parking while accessing such restrooms.
This amendment to Title 49 would exempt some employers from the bill including filling and service stations, and restaurants 800-square feet or smaller with restrooms intended for employee use only. The bill doesn’t require employers to construct new restrooms but to give truck drivers the same access as employees or customers.
Commercial truckers and delivery drivers are the lifeline of our supply chain of supplies, products, and consumables. Working tirelessly all hours, during holidays and weekends, and throughout the pandemic, they continue to deliver critical food and emergency supplies to companies everywhere. Employers have the privilege of demonstrating gratitude to truckers and delivery drivers with a positive work environment.
The benefits of allowing truckers and delivery drivers the convenience and safety of readily available, sanitary restroom facilities are plenty. They’re able to rest and reset when necessary, which keeps them and others safer on the roads. Equally important, restroom availability prevents drivers from having to search for available facilities elsewhere, allowing them to keep a timely delivery schedule, limit supply chain delays, and ultimately lower costs for employers and customers.
The proposed Trucker Bathroom Access Act will require retailers, warehouses, and other establishments with existing restrooms to provide access to truckers and delivery drivers who are loading or delivering cargo. Access to restrooms keeps them refreshed and ready to deliver essential supplies to companies across the country.
Hi everyone! Welcome to the monthly news roundup video, where we’ll go over the most impactful environmental, health, and safety news. Please view the content links in the transcript for more information about the topics I’ll be covering today. Let’s get started!
Effective January 15, OSHA penalties increased 3.2 percent for inflation. Most penalties increased to $16,131. Willful and serious violations, however, increased to $161,323.
Construction workers aged 45 and older suffer more severe injuries and higher associated costs than other age groups. Most injuries are due to slips, trips, and falls.
Washington State updated its process safety management rules to better protect workers in petroleum refineries from the hazards of volatile chemicals. The rules take effect December 27, 2024.
Bloodborne pathogens topped the list of OSHA violations for the healthcare industry in 2023. Hazard Communication was the second most cited standard, followed by respiratory protection.
OSHA Region 2 launched a regional emphasis program that targets tree trimming, tree removal, and land clearing operations. Region 2 includes New York, New Jersey, Puerto Rico, and the U.S. Virgin Islands.
EPA continues to strengthen its regulation of per- and polyfluoroalkyl — or PFAS — substances. A new rule prevents facilities from using any of the 300+ inactive PFAS before EPA conducts a risk determination and, if necessary, regulates the activity.
Thanks for tuning in to the monthly news roundup. We’ll see you next month!
The Environmental Protection Agency (EPA) is amending the Toxic Substances Control Act (TSCA) regulations for polymers manufactured under the terms of the polymer exemption by extending the submission deadline for reporting. The regulations require that manufacturers (includes importers) of polymers manufactured under the terms of the exemption submit a report of manufacture or import by January 31 of the year subsequent to initial manufacture. On June 7, 2023, EPA amended the exemption reporting requirement to require that the exemption report and accompanying confidentiality claims be submitted electronically. Because EPA experienced technical difficulties with the launch of the new electronic reporting tool, EPA is extending the reporting period for 2024 from January 31 to March 31 to allow manufacturers additional time to submit their reports and accompanying claims to EPA using the electronic reporting tool.

The Environmental Protection Agency (EPA) is proposing a regulation to implement the requirements of the Clean Air Act (CAA) as specified in the Methane Emissions Reduction Program of the Inflation Reduction Act. This program requires the EPA to impose and collect an annual charge on methane emissions that exceed specified waste emissions thresholds from an owner or operator of an applicable facility that reports more than 25,000 metric tons of carbon dioxide equivalent of greenhouse gases emitted per year pursuant to the petroleum and natural gas systems source category requirements of the Greenhouse Gas Reporting Rule. The proposal would implement calculation procedures, flexibilities, and exemptions related to the waste emissions charge and proposes to establish confidentiality determinations for data elements included in waste emissions charge filings.

Safety has the workforce brimming with color. In fact, 29 CFR 1910.144 and 1910.145 tell us precisely what OSHA expects for safety color coding to identify hazards in the workplace. Signs, warning labels, symbols, and other color coding in your facilities should have your employees seeing red. But what if they can’t?
Though rare, color blindness is the inability to distinguish between colors as most people do. This makes it difficult for workers to see colors intended to protect them from harm. Color blindness can vary, making it difficult to distinguish between red and green or blue and yellow hues - the very shades of safety.
Some individuals can’t see any colors, which is called monochromacy. Workers with this type of color blindness may have trouble seeing clearly and may be more sensitive to light. Employers must collaborate with these employees to ensure alternative measures are taken to protect their eyes and clearly communicate warnings and hazards.
The color identifiers below differentiate the various levels of risk and hazards for workplace safety. Employers must ensure workers with color blindness are able to understand hazards in the workplace and the meaning of signs and warning labels.
RED - identifies fire and fire protective apparatus, danger, and emergency stops. It marks areas near open flames or flammable materials, fire extinguishers, and where workers are directed to stop an action.
ORANGE - warns workers of hazardous parts of equipment that could physically harm people or the facility. Typically used as labels on machinery, orange may also be used on signs, hard hats, safety vests, and other objects.
YELLOW - designates caution and is used for marking physical hazards, such as falling, pinch points, contact hazards, and other similar hazards.
GREEN - identifies directional safety information. This includes pointing workers to emergency egresses, safety showers or eyewash stations, first aid stations, and other safety equipment.
BLUE - not always safety-related, provides information regarding a particular location, process, or item. Employers may use blue signs to convey workplace policies, instructions, or locations, such as “Employees Only.”
PURPLE - often combined with yellow, alerts workers to radiation hazards.
BLACK/WHITE - provides instructional and directional information. This includes speed limits, one-way traffic, and aisle markings.
Having a standardized color-coding system for safety is effective for alerting employees of workplace hazards - if they can see the colors properly. For those who can’t, employers must ensure these workers understand the hazards and warning signs throughout the workplace.

Not only are employers required to ensure workers understand warning signs and colors, but they must also protect workers from becoming color blind. That’s right - color blindness can be acquired. Exposure to lead or carbon disulfide can cause color blindness, even at low levels. Terminal illness and alcohol consumption can also contribute to color blindness, so employers should promote health as part of their safety and health programs.
Color blindness is considered a disability according to the Americans with Disabilities Act (ADA). Employers are required to reasonably accommodate employees with disabilities.
Employers must ensure employees with color blindness are able to understand hazards in the workplace and the meaning of signs and warning labels. The ADA requires employers to make reasonable accommodations for workers with disabilities, including color blindness.
The 150 air-mile exemptions, which are in the regulations at 395.1(e)(1) and (2), allow a driver to use a time record in place of a log, provided that certain conditions are met. While this is possibly the most widely used hours-of-service exemption, it may be the most commonly misused exemption, as well.
To be able to use this logging exemption in 395.1(e)(1), the driver must:
The company must retain the time record and have it available for inspection for six months.
Need more info? View our ezExplanation on the 150 air-mile exception. |
If the driver cannot meet the terms of the exemption (he or she goes too far or works too many hours), the driver must complete a regular driver’s log for the day as soon as the exemption no longer applies.
If the driver has had to complete a log 8 or fewer days out of the last 30 days, the driver can use a paper log for the day. If the driver had to complete a log more than 8 days out of the last 30 days, the driver needs to use an electronic log for the day (unless one of the ELD exemptions applies, such as operating a vehicle older than model year 2000).
When a property-carrying driver is operating under the 150 air-mile exemption, the driver is also exempt from having to take the required 30-minute break (see 395.3(a)(3)(ii)).
If the driver began the day as a 150 air-mile driver and has driven more than 8 consecutive hours without a break, and something unexpected happens and the driver can no longer use the 150 air-mile exemption, the driver must stop and immediately take the 30-minute break as well as start logging. If the driver went outside of the 150 air-mile area before the driver had 8 hours of driving without a break from driving, the driver would be expected to take the break at the appropriate time.
Here are some of the common myths and misunderstandings about the 150 air-mile exemption:
The 150 air-mile exemption at 395.1(e)(2) only applies to drivers that: Operate property-carrying vehicles that do not require a CDL to operate, and Stay within the 150 air-miles of their work reporting location.
If the driver stays within the 150 air-mile radius of the work reporting location, and returns to the work reporting location within 14 hours on 5 of the last 7 days, and 16 hours on 2 of the last seven days, the driver is allowed to use a time record in place of a log.
If the driver does not meet the terms of the exception, the driver will need to complete a log for the day. If the driver had to log more than 8 days out of the last 30 days, the driver will need to use an electronic log for the day. All of the other issues discussed above would apply to these drivers as well.
If you have drivers that use these exemptions, you will need to check time records to make sure they are complying with the appropriate time limits. You will also need to check movement records to verify that the drivers using these exemptions are staying within the mandated area (within 150 air-miles of the work reporting location for the day).
If a driver is over the hours limit, or has gone too far, you need to verify that the submitted a log for the day, either paper or electronic, depending on how many days the driver had to log out of the previous 30 days.
During an audit, if it is discovered that your drivers are using these exemptions incorrectly, you will be cited for not having drivers’ logs when required. Each day this occurred will be another violation, so the fine could be rather large if you are not managing the use of these exemptions!
When drivers fail a DOT test or engage in other prohibited drug or alcohol behavior, their commercial driving careers are stalled until specific steps in rehabilitation and treatment are completed.
Read our FAQ: What happens if a DOT return-to-duty or follow-up test is canceled? |
A commercial driver is required to go through the DOT return-to-duty process if:
Actual knowledge occurs when information is provided to the motor carrier indicating a DOT testing violation. This might be learned through:
When a motor carrier learns of a testing violation on a new hire, it must obtain proof that the driver has completed the return-to-duty process. Otherwise, the motor carrier would have to begin the return-to-duty process or pick up where it left off.
To resume a safety-sensitive function, the driver must complete the following return-to-duty steps in Subpart O of Part 40.
When drivers engage in prohibited drug or alcohol behavior, they must be immediately removed from performing all safety-sensitive functions. If on a dispatch, a driver must be told of the test result and instructed to park the vehicle. This notification often involves making arrangements to get the driver home and continue the run with different driver.
The employer must present the driver with a list of substance abuse professionals (SAPs) who have the appropriate credentials and DOT training to perform driver evaluations. The list must be given without a fee and made available to the driver (or driver applicant) whether or not the carrier retains the driver.
If the motor carrier does not have another face-to-face meeting with the driver, this list may be mailed or emailed to the driver.
For drug test results, the medical review officer (MRO) will report the violation to the Clearinghouse. This includes shy bladder scenarios without a valid medical explanation.
Failed alcohol tests (.04 or greater BAC), actual knowledge, and certain refusal to test scenarios are reported by the motor carrier to the Clearinghouse.
After the SAP list is given to a driver, the motor carrier cannot force a driver to begin the process. Nevertheless, to resume safety-sensitive functions, the driver must seek a face-to-face evaluation from a qualified SAP as a first step.
Payment of the evaluation is not required of the employer. Instead, it is based on labor-management agreements and healthcare benefits.
The SAP’s referral to an education and/or treatment program is based on a clinical evaluation of the driver during the face-to-face meeting. The SAP should have a working knowledge of what programs and counselors are available.
The SAP may take into consideration the driver’s ability to pay and insurance coverage. Once a SAP-approved provider has been agreed upon with the driver, the SAP will facilitate the referral and provide the program with the diagnostic determinations that led to the treatment plan. Programs range from outpatient treatment to partial or full in-patient resources.
Once the treatment plan has ended, the SAP will determine if it was a success. This decision is based on information provided by the education and/or treatment program and another face-to-face evaluation with the driver.
This second evaluation will result in one of three determinations:
If the SAP is satisfied with the driver’s ability to return to driving, the SAP will issue a report to the designated employer representative (DER). This report will list any continuing treatment and education, if required, and the number of DOT follow-up drug and/or alcohol tests required in a given time frame. The driver will be required to have a minimum of six unannounced follow-up tests in the first 12 months following the return to a safety-sensitive function. The SAP may require follow-up testing for up to five years.
For all Part 382 violations occurring since January 6, 2020, the SAP is required to report the successful completion of the evaluation and treatment to the Clearinghouse, provided the driver has designated the SAP in the driver’s personal Clearinghouse account.
The DER must wait for the go-ahead in the SAP report before sending the driver for the return-to-duty drug and/or alcohol test. All return-to-duty drug tests are performed under direct observation. The motor carrier must report a negative return-to-duty test to the Clearinghouse. In order for the “prohibited” status to be lifted from the driver’s record, both the SAP and motor carrier submission must be entered onto the driver’s record.
Once the Clearinghouse is no longer showing an unresolved testing violation, the driver can return to a safety-sensitive function.
Editor’s Note: Violations occurring prior to January 6, 2020, are not tracked in the Clearinghouse. Instead, the motor carrier would use the SAP report as a green light to perform the return-to-duty test, and once the negative test result is received, the driver can resume a safety-sensitive function.
After the driver returns to safety-sensitive functions, the motor carrier must carry out the unannounced follow-up tests under direct observation as prescribed in the SAP report. The DER must ensure that the tests do not have any discernible pattern.
The follow-up tests are in addition to any other DOT-required tests (e.g., random, post-accident). For instance, you cannot use a follow-up test as a substitute for a random test or vice versa.
If the driver leaves the motor carrier prior to the completion of the very last follow-up test, the next employer(s) must pick up where the process left off.
When the follow-up program is complete, the motor carrier under whose program the last test was performed must report this to the Clearinghouse. If the violation predates the Clearinghouse, the employer does not report the completed follow-up program to anyone.
If the motor carrier fails to begin or continue with a driver’s DOT return-to-duty process and follow-up testing, it is an acute violation that could cost the company up to $15,876. Allowing this driver to operate a CMV puts the carrier at risk of negligent entrustment claims if there is a crash.
The FMCSA is planning to test the effects of letting commercial truck drivers “pause” their 14-hour on-duty limit by up to 3 hours per day.
The agency is hoping to enlist up to 400 drivers to participate in its three-year “Split Duty Period Pilot Program.” Participants would be allowed to use one off-duty break of between 30 minutes and 3 hours to pause the 14-hour driving window, as long as they take 10 consecutive hours off duty at the end of the day. The pause should enable drivers to reduce fatigue, avoid congestion, reduce the pressure to speed, and be more productive, the FMCSA says.
Normally, short breaks taken during a driver’s day must be subtracted from the driver’s 14-consecutive-hour window during which driving is allowed.
For more information, see our ezExplanation on the 14-hour on-duty rule. |
Under new rules in effect on September 29, 2020, some truck drivers can pause their 14-hour limit with a break of 2 hours or more, but only if they also spend at least 7 hours in a sleeper berth (see below). Under the pilot program, drivers could pause the clock with off-duty time alone, without the need for a sleeper berth. This idea was proposed back in 2019 but didn’t find its way into the recent rule changes because the FMCSA didn’t have enough data to justify it.
As required by law, the FMCSA is gathering public input on the proposal until November 2nd. It will then decide whether to implement the program. After the program concludes, the agency will need to report to Congress on its findings before it could proceed with any changes to the hours-of-service regulations.
Participation in the pilot program would be limited to between 200 and 400 commercial driver’s license (CDL) holders from companies of all sizes, with each driver participating for up to one year. Motor carriers that want to enroll in the program will need to apply via an FMCSA website which could be available late this year. Comments on the proposal may be submitted online at www.regulations.gov under docket number FMCSA-2020-0098.
Truck drivers who fall under the federal hours-of-service rules can already pause their 14-hour clock with a short rest break, as of September 29, 2020 (see log image). This is known as the “split sleeper-berth” option, and it works like this:
Key to remember: The FMCSA plans to test the safety of allowing truck drivers to pause their 14-hour clock with a rest break of up to 3 hours, even if they don’t have a sleeper berth. The pilot program could open later this year.
As of January 1, 2023, heavy-duty trucks and buses with engines from model years 2007 to 2009 operating in California must be either:
This is the final step in the phase-in of the Truck and Bus regulation. Covered vehicles originally built with engines older than model year 2006 must have already been replaced or retrofitted.

One issue that has come up is new vehicles are not available for delivery before January 1, 2023. This means fleets that operate in California that cannot get a replacement vehicle will be faced with the choice of either retiring their 2007 to 2009 engine vehicles without a replacement or operating in violation as of January 1, 2023.
However, the California Air Resources Board (CARB), the agency that oversees the Truck and Bus program, is aware of the situation and has provided an exemption. If the company has a written contract to purchase a new vehicle to replace a vehicle with a 2007 to 2009 engine in place before September 1, 2023, the existing vehicle can be operated until the replacement is placed in service.
To use this exemption, the company must register in CARB’s Truck Regulation Upload, Compliance, and Reporting System (TRUCRS) and report the use of the exemption. This is especially important to California-based companies as vehicle registration is tied to compliance with the Truck and Bus regulations requirements.
As of January 1, 2023, California will be placing roadside emissions monitoring devices (REMD) at locations around the state. These devices check emissions on any vehicle that passes it. If the device determines a vehicle may be a high emitter, the owner will receive a Notice to Submit to Testing. This will require the vehicle to be brought in to a “referee” location where the emissions and emissions components can be inspected.
These Truck and Bus requirements go into effect on January 1, 2023, and only apply to vehicles operating in California.
Most motor carriers review their roadside inspection reports for the obvious reasons: fixing mechanical defects and identifying unsafe or noncompliant driver behavior.
Some violations are easy to decipher, such as a burned-out light bulb or exceeding the speed limit by a specific range. Others take a little more to figure out, such as doing the math to determine when and how a driver exceeded hours-of-service (HOS) limits. Then there are all those 392.2 violations with suffixes. Some count against a carrier’s Compliance, Safety, Accountability (CSA) scores, while others do not, depending on whether they contribute to causing a crash.
One that often baffles motor carriers is 392.2C.
Section 392.2C is enforcement’s code for “failure to obey traffic control device.” The C stands for control.
The citation appears in the severity table for the Unsafe Driving BASIC (Behavior Analysis and Safety Improvement Category). The violation has been assigned a value of 5 out 10, with 10 being the most severe. The violation is used when calculating both the carrier’s and driver’s Unsafe Driving BASIC scores.
In most instances, the traffic control device is not a signal light or stop or yield sign. Rather, it is the sign that instructs the driver to pull into a weigh station.
View our Weigh Stations ezExplanation for additional information. |
The vehicles that must stop at scales and inspection locations vary from state to state and even from location to location within a state. The “weigh scale ahead” or similar sign should be the driver’s guide.
If the sign reads:
Often those who operate commercial vehicles not requiring a commercial driver’s license, such as a large pickup truck or small box truck, mistakenly believe weigh scale inspections are just for larger rigs.
If a driver goes past a weigh station without pulling in as directed by a traffic control device, enforcement will pursue and pull over the driver. The officer will then escort the driver back to the weigh station for a roadside inspection.
Even if the driver was honestly confused whether the sign applied to the vehicle, it is too late. And more than likely enforcement’s interest has been piqued. It is highly unlikely the driver will be waived through at this point, and 392.2C will be entered on the roadside inspection report.
CSA’s enforcement model suggests finding the root cause of roadside inspection violations to prevent future occurrences and ultimately improve BASIC scores.
A violation of 392.2C may have one of several root causes, such as:
Whatever the reason, it must be addressed with the driver. Corrective actions range from refresher training to termination. If the driver was trying to avoid enforcement for other reasons (drugs, alcohol, over HOS limits), these other violations need to be addressed accordingly.
Key to remember: Failing to obey a traffic control device will be used in calculation of the CSA Unsafe Driving BASIC scores. Motor carriers should address the root cause of the violation so it does not recur.
A workplace safety definition for “safety-sensitive position” may lead some motor carriers to mistakenly put employees who don’t qualify in their DOT drug and alcohol testing program.
The Federal Motor Carrier Safety Administration (FMCSA) clearly defines a safety-sensitive position.
It is one where the employee is expected to operate a commercial motor vehicle (CMV) requiring a commercial driver’s license (CDL). Only these drivers can be placed in the motor carrier’s DOT drug and alcohol testing program under 49 CFR Part 382.
As a result, a carrier would not classify a forklift operator, driver helper, and other positions as safety sensitive for purposes of testing under Part
A driver who operates an FMCSA-regulated vehicle that does not require a CDL fits within the scope of workplace safety-sensitive duties, but not FMCSA.
For property-carrying vehicles, a non-CDL CMV is one that is:
For passenger carriers, a non-CDL CMV is designed to transport 9-15 passengers, including the driver, for compensation.
Even though the above vehicles and drivers are subject to the bulk of FMCSA’s safety regulations, the vehicles (and subsequently the drivers) do not qualify for CDL licensing or FMCSA testing.
If the driver happens to hold CDL, it still does not qualify as a safety-sensitive position. Applicability is always based on whether the employee is assigned to operate a CDL CMV.
Non-CDL CMV drivers are prohibited from operating while impaired under 49 CFR 392.4 and 392.5, but there is no testing mechanism under DOT authority. Testing would be best practice (non-DOT) and managed under the workplace drug program.
If a motor carrier mistakenly uses the workplace criteria for its DOT testing, the number and types of positions placed in the random pool far exceed commercial drivers.
For the general workforce, the term “safety sensitive” has been tossed around, but never clearly defined by OSHA (Occupational Safety and Health Administration). Many safety professionals tie the term to OSHA’s General Duty Clause (GDC), which requires that employers provide all workers with a safe and healthful workplace.
Specifically, the GDC requires employers to recognize hazards that cause or likely will cause death or serious physical harm. Any job title that is likely to cause death or serious harm to someone — including the employee, coworkers, or the general public — is usually put on a list of safety-sensitive positions.
The employer must look at each job’s hazards and decide if the position is classified by its organization as safety sensitive. Examples may include:
Even someone who works as a roofer may be considered a safety-sensitive position because the employee could trip and fall from a high elevation, causing serious personal harm.
Key to remember: When assembling the list of names for your DOT testing program, only include those individuals who are expected to operate a CDL CMV.
With the labor market still tight, employers might choose to hang onto employees even if they’re underperforming. But what about when complaints are rolling in from different angles? Take, for example, a lackluster supervisor who’s annoying employees and disappointing customers.
An employer could be hesitant to let the supervisor go, especially if there’s no documentation backing up claims of misconduct. The employer must weigh their options to decide if putting the supervisor on a performance improvement plan (PIP) or moving right to termination is the ideal choice.
At-will employment
For starters, in most states employers may terminate an employee at-will, meaning they can fire employees for pretty much any reason as long as it doesn’t discriminate against someone in a protected class based on sex, age, race, religion, etc. Employers also cannot terminate in retaliation for an employee making a claim of harassment, discrimination, or safety concerns.
Aside from these limits, employers can terminate employees for good cause, bad cause, or no cause at all.
PIP or terminate
Deciding whether to put an employee on a PIP or terminate must be decided on a case-by-case basis.
A PIP is usually for job performance issues (hence, performance improvement plan). This could mean anything from not making enough sales to being inept at the job’s essential functions. If job performance doesn’t improve under the PIP, termination may be the end result depending on company policies and practices.
Even if an employee has job performance issues, the employer can terminate without going through the PIP process first, unless the usual process is to implement a PIP with employees who have had similar problems. In that case, not doing a PIP could be seen as discrimination against an employee, especially if the person falls into a protected class.
Workplace misconduct, however, is another situation altogether. This could be anything from a one-off poor joke to pervasive harassment. Snapping at customers or coworkers (or worse), for example, is a conduct issue. An employer could issue a warning or move right to termination if the behavior is clearly illegal or a serious threat to workplace safety.

Termination tips
If an employer decides to terminate, they should treat the employee as respectfully as possible during the termination process. Also, an employer should carefully and clearly communicate the job-related reasons for the termination to avoid any hint of discrimination. Lastly, an employer should document the reasons and reiterate the steps taken leading up to the termination and keep those records handy in case the employee files a wrongful termination lawsuit.
Key to remember: Employers sometimes struggle when making termination decisions. Having a process in place and documenting steps along the way can help if a case lands in court.
Wage overpayment errors happen for many reasons — from clerical mistakes to payroll system snafus.
Regardless of the reason, employees are not necessarily entitled to keep the extra money, and employers need to know their obligations for recouping it.
Under the federal Fair Labor Standards Act (FLSA), employers don’t need an employee’s permission to recoup wage overpayments. The extra money is seen as a loan or a wage advancement to the employee.
Because of this, employers are generally free to recoup the overpayment from the next paycheck — even if such a deduction cuts into the minimum wage or overtime pay due the employee under the FLSA.
State laws, however, may have greater restrictions. For example, New York employers may only make deductions from an employee’s wages for “an overpayment of wages where such overpayment is due to a mathematical or other clerical error by the employer.”
There are also limitations on the timing and duration, frequency, and method and amount of recovery.
The bottom line is, employers should try to avoid getting themselves into an overpayment situation in the first place. Supervisors should closely review their direct reports’ timesheets to catch errors before paychecks are issued
Also, employees should be encouraged to review their pay stubs for accuracy to help catch mistakes sooner rather than later.
If a mistake happens, employers should do their due diligence to communicate with the affected employees and make a reasonable plan to recoup the funds (provided it’s allowed under state law) so as not to cause any unnecessary financial harm to employees.
Wage overpayment errors can and will occur. Employers need to know their obligations under both federal and state laws before recouping money.
Employers sometimes get tripped up on how to calculate the 1,250 hours worked eligibility criterion when employees need leave under the Family and Medical Leave Act (FMLA).
Does working overtime count toward the 1,250?
Recently, someone asked if overtime hours counted toward the 1,250 hours worked requirement (it does).
All hours actually worked apply to the 1,250, whether overtime or regular time, even if the overtime is not mandatory.
The 1,250 hours is calculated in relation to when the leave will begin, not when the employee puts an employer on notice of the need for leave.
Whether an employee is allowed to work overtime, however, is generally up to company policy. As far as pay goes, remember, if the employee is nonexempt (“hourly”) and works any overtime (mandatory or voluntary) the employee must be paid time and one-half for all hours worked over 40 within the workweek.
More about FMLA leave requirements
To be eligible to take FMLA leave, employees must:
Whether an employee has worked the minimum 1,250 hours is calculated based on determining compensable hours or work under the Fair Labor Standards Act (FLSA).
Calculating the 1,250 hours worked
When it comes to figuring out if an employee has worked at least 1,250 hours, it can get tricky. As was mentioned above, all hours worked, regular and overtime, must be counted.
Hours not worked should not be counted. The “not worked hours” include such time off as vacation time, sick leave, paid or unpaid holidays, or any other time in which an employee isn’t actually working — which can include disability, bereavement, FMLA and other forms of leave.
Once an employee meets the three eligibility criteria, including the 1,250 hours worked, for a particular leave reason, the employee remains eligible for the duration of the 12-month leave year period.
If the employee needs leave for another, different reason, eligibility would be recalculated.
Key to remember: All hours worked must be included in the 1,250 hours criterion when determining whether an employee is eligible for FMLA leave. Hours that aren’t worked (like vacation) are not included.
When an employee is on leave under the Family and Medical Leave Act (FMLA), the employer must maintain benefits under the company’s group health plan.
Thus, employees generally must continue paying their share of the health insurance premiums.
But how do employees pay their share of the premiums when FMLA leave is unpaid? Employers may offer three payment options:
Employers may allow a combination of these options, such as pre-pay for part of the leave and catch-up for the remainder. Below is a breakdown of the three available payment options.
When unpaid FMLA leave is foreseeable, employers may allow employees to pre-pay their premiums. For example, if an employee is adopting a child and requests several weeks for bonding time but does not have enough vacation to cover the entire absence, an employer could allow the employee to pre-pay his or her premiums for the portion of the leave that would be unpaid.
Employers may not require an employee to pre-pay, so this cannot be the only option offered.
If an employee chooses this option, however, employers may collect premiums on a pre-tax basis – with one exception. If the absence will extend into the next tax year (such as leave from December through January), only the premiums for the current tax year may be pre-paid with pre-tax income. The IRS does not allow employees to defer untaxed income from one year to the next.
In this example, the premiums for January could either be pre-paid with after-tax income, or the employee could elect one of the other options (pay-as-you-go or catch-up).
Under the pay-as-you-go option, employees pay their share of the premiums based upon the agreed terms made between the employer and employee. These payments are usually made on an after-tax basis.
For example, the employee might mail in a personal check every two weeks. If the employee fails to send in the checks, or otherwise fails to make payments using the agreed-upon system, the FMLA does allow employers to drop coverage after giving specified notices of non-payment.
Dropping coverage would likely cause some administrative headaches, and some insurers may refuse to do this because the employee would have to be reinstated to the health plan upon return from FMLA leave.
Therefore, employers may prefer to continue coverage by paying the employee’s share of the premiums, then use the catch-up option once the employee returns to work. Some insurance carriers recommend this as an alternative to dropping coverage.
Under the catch-up option, the employer and employee agree that the employee will not pay premiums until he or she returns from leave.
This option might be used when the need for FMLA leave was not foreseeable, such as having to care for a parent who was unexpectedly hospitalized.
To use this option, the employer and employee must agree in advance that:
When the employee returns, the employer collects the current premiums plus any catch-up payments, perhaps taking double premiums, until caught up. Contributions under the catch-up option may be taken on a pre-tax basis.
The IRS regulations indicate that, if the employee chooses the pay-as-you-go option, but fails to make the required payments, you may change to the catch-up option even without the employee’s prior agreement.
Employees on unpaid FMLA leave must still pay their share of health insurance premiums by either pre-paying, paying as they go, or making catch-up contributions upon returning to work.
A new year often begins a new round of employee performance reviews. Since the Family and Medical Leave Act (FMLA) allows eligible employees to take up to 12 (or 26) weeks of leave, many events can occur during an employee’s leave, including the employee’s pre-scheduled performance review. Such reviews might take place on an annual or other scheduled basis. How you treat the timing of those reviews should include some thought.
If, for example, Jo Employee takes 12 weeks of FMLA leave, during which her annual performance review is scheduled, here are some questions to ponder:
Delaying a review
An annual performance review generally takes into consideration a full years’ worth of work. Some employers think it’s best to delay the performance review by the same amount of time an employee took FMLA leave to capture an entire years’ work. This practice, however, might risk running afoul of one of the cornerstones of the FMLA: Returning the employee to his or her position, including the equivalent pay, benefits, and working conditions.
The issues can be particularly concerning if the performance review affects wage increases or other compensation.
What the regulations say
The FMLA regulations indicate that an equivalent position includes equivalent pay, which includes any unconditional pay increases that may have occurred during the FMLA leave period. Equivalent pay also includes bonuses or payments, whether discretionary or non-discretionary. FMLA leave cannot undermine the employee’s right to such pay.
Furthermore, “… employers cannot use the taking of FMLA leave as a negative factor in employment actions, such as hiring, promotions, or disciplinary actions; nor can FMLA leave be counted under no fault attendance policies.” [29 CFR 825.220(c)]
Avoiding a negative factor
Therefore, you would need to look at whether delaying an employee’s performance review could be seen as having a negative factor for the employee.
If, for example, Jo Employee took 12 weeks of leave from April through June, during which she would otherwise have obtained a pay increase in May, but you delayed this increase until September (so you could use a full 12 months of work), you may have violated the equivalent pay provision. If delaying a review creates a new review schedule going forward, the negative impacts could continue.
If, however, a pay increase is conditioned upon seniority, length of service, or work performed, you would grant it in accordance with your policy or practice as applied to other employees on an equivalent leave status for a reason that does not qualify as FMLA leave.
In other words, don’t treat an employee on FMLA leave differently than you would an employee on other forms of leave.
Key to remember: It might be less risky to keep the performance review on schedule and prorate wage increases to account for FMLA leave.
As of January 1, California and Washington have new marijuana laws that restrict testing for the drug.
Both states, which have legalized recreational and medical use, put limits on pre-employment testing for cannabis at the start of the year.
Washington’s rationale for the new law is that a pre-employment marijuana test limits job opportunities for those who use cannabis, because an applicant will test positive for up to 30 days after using it. The new law is designed to prevent the restriction of job opportunities based on an applicant’s past cannabis use.
California’s law notes that a test for marijuana detects past use of the drug, but does not prove whether or not an individual is impaired by it. Its protections are broader than Washington’s, and apply to employees as well as applicants. As a result, they also restrict reasonable suspicion, post-accident, and random marijuana tests.
Testing restrictions in California and Washington
The new state laws take aim at tests measuring nonpsychoactive cannabis metabolites. These metabolites are created by the body after cannabis is smoked or consumed in an edible.
Their presence indicates that cannabis has been used, but the fact that they are present does not prove at a person is impaired by the drug.
The laws do not allow employers to make employment decisions based on marijuana tests that show the presence of nonspychoactive cannabis metabolites. While tests that do not detect these metabolites are technically allowed, from a practical standpoint they are difficult to find.
Current drug tests that detect the presence of THC (the chemical in marijuana causing impairment) are likely to detect nonpsychactive metabolites as well. Other tests that rely on baseline performance to prove impairment would be difficult to use for applicants, as there would be no previous information to use for comparison.
Exceptions to state laws
Both states have exceptions that allow employers to conduct marijuana tests under certain circumstances.
Washington’s restrictions do not apply to:
California’s law allows marijuana tests for:
An employee in the building and construction trades.
Applicants or employees hired for positions that require a federal government background investigation or security clearance in accordance with regulations issued by the U.S. Department of Defense or equivalent regulations applying to other agencies.
Testing conducted under state or federal laws requiring applicants or employees to be tested for controlled substances.
3 steps for employers to take
To make sure workplace drug testing in California and Washington is conducted appropriately, employers should:
Update pre-employment drug testing policies in California and Washington so they comply with the new laws.
Identify positions that are exempt from testing restrictions. When a position qualifies for an exception, make applicants aware that that marijuana testing will be conducted.
Train hiring managers and supervisors about the new requirements. Make sure they understand when marijuana testing is not allowed.
Key to remember: California and Washington have new marijuana testing restrictions that are in place as of January 1. Workplace policies and practices need to be updated to comply with the new laws.
The COVID-19 outbreak created a shortage of latex and nitrile gloves in many workplaces.
Latex and nitrile gloves are used extensively in health care, and their disposable (single use) nature meant that large quantities were consumed during the peak of the pandemic. The shortage was also worsened because of hoarding by some consumers. In addition, certain businesses and government agencies began using these gloves to protect employees, even if their workers didn’t normally require gloves on the job.
If you have trouble obtaining your staff’s usual gloves, be prepared to identify feasible alternatives. You don’t want to endanger them by having them wear any old gloves they find lying around.
To identify alternatives for workers who rely on latex or nitrile gloves as PPE, you must know which chemicals workers handle or come in contact with. That’s because all glove materials are not suitable for all hazards.
Evaluate which materials offer appropriate protection from the specific chemicals that workers handle to select appropriate alternative gloves.
Here’s a summary of glove types and the protection given to help evaluate alternatives.
Butyl gloves protect against a variety of chemicals such as peroxide, highly corrosive acids, strong bases, alcohols, aldehydes, ketones, esters and nitrocompounds. Butyl gloves also resist oxidation, ozone corrosion and abrasion, and remain flexible at low temperatures. However, they do not perform well with aliphatic and aromatic hydrocarbons and halogenated solvents.
Natural (latex) rubber gloves have good elasticity and temperature resistance, and resist abrasions well. They protect against most water solutions of acids, alkalis, salts, and ketones. Latex gloves may cause allergic reactions and may not be appropriate for all employees. Hypoallergenic gloves, glove liners, and powderless gloves are possible alternatives for employees who are allergic.
Neoprene gloves protect against hydraulic fluids, gasoline, alcohols, organic acids, and alkalis. Their chemical and wear resistance are generally better than gloves of natural rubber.
Nitrile gloves are intended for jobs requiring dexterity, and they stand up even after prolonged exposure to substances that cause other gloves to deteriorate. They offer protection when working with greases, oils, acids, caustics, and alcohols but are not recommended for use with strong oxidizing agents, aromatic solvents, ketones, and acetates.
OSHA’s 1910.151(c) standard, Medical Services and First Aid, requires that employers provide emergency eyewashes when employees may be exposed to injurious corrosive materials during the course of their work. Employers have a wide range of eyewash types available to choose from on the market, including portable units (i.e., eyewash bottles). While many employers use bottles, OSHA says that they can’t be the only eyewash made available to employees, and their use should be limited.
The OSHA standard does not provide a great deal of detail on eyewashes for employers. However, where the regulation is silent, OSHA refers employers to the American National Standards Institute (ANSI) standard Z358.1-2009, “Emergency Eyewash and Shower Equipment,” regarding installation, operation, and maintenance of emergency eyewashes. This includes capacity and flushing requirements. The ANSI standard states that an eyewash must deliver 0.4 gallons of flushing fluid per minute for at least 15 minutes.
As such, ANSI says that an eyewash bottle does not meet these criteria; therefore, it can only be used to support eyewashes that do (i.e., plumbed and self-contained units), but cannot replace them.
The reason for this limitation is that eyewash bottles simply cannot provide the required 15 minutes of flushing. Eyewash bottles typically hold less than a gallon of water, which would supply the user with flushing fluid for approximately 1 minute. Even larger self-contained units (those with bladders) that have a capacity of 5 to 10 gallons would only provide maximum use of about 5 minutes.
In other words, eyewash bottles don’t provide an adequate amount of flushing fluid and cannot be considered a primary means of protection.
For this reason, OSHA warns that the use of eyewash bottles should be limited. In a 1986 memorandum to Regional Administrators, the agency states, “In general, squeeze bottles should not be used except where the hazard severity or distance from plumbed eyewash equipment requires personal equipment at work stations for immediate flushing prior to prolonged flushing at a plumbed or self-contained unit.”
In other words, employers can provide eyewash bottles in instances where plumbed or self-contained units can’t reasonably be provided (e.g., an outside yard) in the immediate work area, but only until they can reach a unit which can provide the amount of flushing fluid necessary to flush the eyes for at least 15 minutes.
OSHA expects the employer to determine the level of the potential risk to employees and provide eyewash (and/or shower) protection accordingly. The severity of the hazard(s) involved is a critical consideration when making this determination. In the past, OSHA has said that 1910.151(c)is meant to cover strong acids and alkalis, and the requirement to provide suitable facilities for quick drenching or flushing depends on the exposure and the strength of the hazardous chemical. Chemicals and materials such as household detergents or cleaners, sawdust, metal filings, etc. would not require emergency eyewash (or shower) under the standard.
If an employer determines that an eyewash is needed, then it must meet the provisions set forth in the American National Standards Institute (ANSI) standard Z358.1. The agency uses the ANSI standard as an enforcement tool. This is clarified in a November 1, 2002, Letter of Interpretation, which says, “If OSHA inspects a workplace and finds unsuitable facilities for quick drenching or flushing of the eyes and body, a citation under 29 CFR 1910.151(c)would be issued. When determining whether the eyewash or shower facilities are suitable given the circumstances of a particular worksite, OSHA may refer to the most recent consensus standard regarding eyewash or shower equipment…”
Need information on eyewash inspections? See our Institute document on Inspections and Maintenance. |
Without the ANSI standard, employers would find it difficult to demonstrate to OSHA exactly how their eyewash and shower units were suitable exclusive to the regulatory language under 1910.151(c) since it’s limited and vague.
Eyewash bottles don’t meet the requirement under 1910.151(c) to provide “suitable” facilities for quick drenching or flushing of the eyes. They cannot be the only eyewash provided in the workplace.
Each year, the National Fire Protection Agency (NFPA) reminds employers not to prop open fire doors for convenience. Propping open doors has become a common violation of fire codes after the pandemic because workers didn’t want to become exposed to germs on common touchpoints.
I know firsthand this is an issue at construction jobsites and remember telling workers not to prop open fire doors in our clients’ facilities. Workers were doing this out of convenience because they carried things into and out of the existing facility. Propping open a fire door, or wedging it open, are serious fire and safety hazards. Keep fire doors closed to prevent smoke and fire from spreading into the fire evacuation route, like a stairwell. OSHA and NFPA don’t prohibit propping open a fire exit door but caution employers against doing this for safety and security reasons.
Fire doors must remain closed, although some may be designed to automatically close when fire and smoke are sensed by jobsite fire detection equipment. To reduce the need to disinfect frequently touched points, workers can push open fire doors using their sleeves by pushing against the push bar instead of using their hands. You can also increase housekeeping efforts and the frequency that doorknobs, handles, and push bars are cleaned throughout the shift.
One way employers try to handle skyrocketing inflation is to manage first aid supplies. But do OSHA regulations allow employers to lock first aid supplies as a way to control costs?
Our experts are often asked whether OSHA permits locking first aid supplies. In a January 23, 2007, OSHA letter of interpretation (LOI), OSHA confirmed that first aid cabinets can be locked. The LOI stated, however, that first aid supplies must be readily accessible in the event of an emergency. Additionally, 29 CFR 1910.151(b) states: “In the absence of an infirmary, clinic, or hospital in near proximity to the workplace which is used for the treatment of all injured employees, a person or persons shall be adequately trained to render first aid. Adequate first aid supplies shall be readily available.”
OSHA defines “readily available” as accessible within three to five minutes and warns that locking first aid supplies, whether kits or cabinets, may limit employee accessibility per the standard. The agency advises that if an employer was relying on first aid services not provided by a clinic, infirmary, or hospital and adequate first aid supplies were not available when needed, then the employer would be in violation of 1910.151(b).
If you’re concerned with supplies being used in a manner not intended by the company, there are ways to manage supplies. For example, employers could use vending machines that allow employees to scan their badges and get basic supplies or personal protective equipment free of charge. This can help employers manage their supply chain and evaluate by whom and for what supplies are being used.
If opting to lock your first aid supplies, remember to make supplies readily accessible (within three to five minutes). This may require that additional keys for locks be made available to multiple personnel at all times when workers are present.
Although their recommendations are non-mandatory, OSHA suggests using the American National Standards Institute (ANSI) for reference to determine what supplies you need to have. The contents for Class A kits listed in the ANSI standard should be adequate for small worksites. Class B kits are designed with a broader range and quantity of supplies to deal with injuries in more complex or high-risk environments (for example, larger operations or multiple operations conducted at the same location).
It’s important to note that although OSHA is still citing ANSI’s 1998 standard, an updated version of the standard, ANSI/International Safety Equipment Association (ISEA) Z308.1-2021, was approved on April 15, 2022, and went into effect on October 15, 2022. Major changes to the standard included:
Determining what first aid supplies should be accessible depends on the workplace hazards and potential injuries. A great place to begin is by assessing your Form 300 injury logs to see the types of injuries already reported. Most employers perform risk assessments, beginning with a review of the Form 300 logs, to drive their decisions. OSHA also provides guidance to employers in 1910.151 Appendix A.
Employers must understand the accessibility risks associated with locking first aid cabinets even though OSHA and ANSI do not prohibit this practice. First aid supplies must be readily accessible (within three to five minutes) in the event of an emergency.
Employers must select a North American Industry Classification System (NAICS) code for every establishment, which usually means a single business location. This code determines whether the establishment is exempt from keeping an OSHA 300 Log. For locations that must keep a 300 Log, the code determines whether the establishment must submit injury data to OSHA by March 2nd.
The NAICS codes get updated every five years, with 2022 as the most current. Adding confusion, different OSHA regulations use different versions of the codes. For example:
Searching codes online may default to the 2022 version, and some codes changed. For example, the 1904.41 appendix lists 4529 for “Other general merchandise stores” which covers retail outlets like dollar stores and variety stores. However, searching that code in the 2022 list shows “no result” since that number changed. The 2022 NAICS code for general merchandise stores is 4552, but that code does not appear in OSHA’s appendix. Employers using the 2022 NAICS codes may incorrectly believe their establishment is not on OSHA’s list.
Employers can search older versions of the NAICS codes at https://www.census.gov/naics/ which also indicates whether a particular code has changed in more recent versions.
In addition to using the NAICS list for the correct year, employers must choose the correct code for each establishment. If a location engages in more than one type of business activity, employers must choose only one NAICS code for OSHA recordkeeping. OSHA says to choose the code for the activity that generates the most revenue or has the most employees.
In some cases, employers can divide a single physical location into more than one “establishment” as defined in 1904.46. To split a single location into multiple establishments, all of the following must apply:
For example, OSHA noted that if an employer operates a construction company at the same physical location as a lumber yard, the employer may consider each business as a separate establishment.
For employers with multiple establishments, the NAICS code for each location should reflect the primary business activity at each establishment. For example, a manufacturing company might have a separate administration office. Using a manufacturing code for the office might not be appropriate, even though it supports the other manufacturing locations. However, NAICS codes starting 5511 for “Management of Companies and Enterprises” might apply.
For example, code 551114 gives examples as follows:
That might better describe a corporate administrative office, if the location does not have any warehousing or manufacturing operations. In fact, codes starting 5511 appear on OSHA’s list of establishments under 1904.2 that are exempt from keeping a 300 Log, so applying the correct code could mean that office doesn’t need a 300 Log at all.
Finally, counting employees gets confusing because some OSHA regulations require counting all employees in the company (combining all locations) and others require counting only the employees at each establishment.
Key to remember: NAICS codes update every five years, and employers must use the correct list, which may differ in various regulations.
Hi everyone! Welcome to the monthly news roundup video, where we’ll review the most impactful environmental, health, and safety news. Please view the content links in the transcript for more information about the topics I’ll be covering today. With that said, let’s get started!
For the 13th year in a row, fall protection for construction topped OSHA’s list of violations. In fiscal year 2023, there were over 7,000 recorded violations, up from 5,250 in fiscal year 2022.
Workers who are exposed to lead in industries such as painting, battery manufacturing, and building renovation risk bringing lead home on their clothing and personal items. Take-home lead can contaminate a worker’s car and home, posing an exposure risk to family members. A new NIOSH publication outlines steps workers can take to minimize this risk.
Private industry employers reported 2.8 million nonfatal workplace injuries and illnesses in 2022. This is a 7.5 percent increase over 2021. The increase is due to a rise in both illnesses, which were up 26.1 percent, and injuries, which were up 4.5 percent. Respiratory illness cases drove the spike in reported illnesses.
OSHA faces significant challenges in ensuring worker safety, particularly in high-risk industries. This is according to a report from the Office of Inspector General, or OIG. Among OSHA’s top challenges are verifying timely hazard abatement, employer reporting, completing inspections, workplace violence, and protecting workers from crystalline silica.
And finally, turning to environmental news, a recent EPA rule requires covered facilities to include all quantities of per- and polyfluoroalkyl substances, or PFAS, on their Toxics Release Inventory reports. The rule also mandates that suppliers notify product users of the presence of any chemicals of special concern contained in their mixtures and products.
Thanks for tuning in to the monthly news roundup. We’ll see you next month!
