(d) Be sealed to prevent the entry of exhaust fumes into the passenger compartment.

S6.2 Location of the tether anchorage.

S6.2.1 Subject to S6.2.1.2, the part of each tether anchorage that attaches to a tether hook must be located within the shaded zone shown in figures 3 through 7 to this section of the designated seating position for which it is installed. The zone is defined with reference to the seating reference point (see §571.3). (For purposes of the figures, “H Point” is defined to mean seating reference point.) A tether anchorage may be recessed in the seat back, provided that it is not in the strap wrap-around area at the top of the vehicle seat back. For the area under the vehicle seat, the forwardmost edge of the shaded zone is defined by the torso line reference plane.

S6.2.1.1 [Reserved]

S6.2.1.2 In the case of a vehicle that—

(a) Has a user-ready tether anchorage for which no part of the shaded zone shown in Figures 3 to 7 of this standard of the designated seating position for which the anchorage is installed is accessible without removing a seating component of the vehicle; and

(b) Has a tether strap routing device that is—

(1) Not less than 65 mm behind the torso line for that seating position, in the case of a flexible routing device or a deployable routing device, measured horizontally and in a vertical longitudinal plane; or

(2) Not less than 100 mm behind the torso line for that seating position, in the case of a fixed rigid routing device, measured horizontally and in a vertical longitudinal plane, the part of that anchorage that attaches to a tether hook may, at the manufacturer's option (with said option selected prior to, or at the time of, certification of the vehicle) be located outside that zone.

(c) The measurement of the location of the flexible or deployable routing device described in S6.2.1.2(b)(1) is made with SFAD 2 properly attached to the lower anchorages. A 40 mm wide nylon tether strap is routed through the routing device and attached to the tether anchorage in accordance with the written instructions required by S12 of this standard. The forwardmost contact point between the strap and the routing device must be within the stated limit when the tether strap is flat against the top surface of the SFAD and tensioned to 55 to 65 N. In seating positions without lower anchorages of a child restraint anchorage system, the SFAD 2 is held with its central lateral plane in the central vertical longitudinal plane of the seating position. The adjustable anchor attaching bars of the SFAD 2 are replaced by spacers that end flush with the back surface of the SFAD.

S6.2.2 Subject to S6.2.2.2, the part of each tether anchorage to which a tether hook attaches must be located within the shaded zone shown in figures 3 through 7 to this section of the designated seating position for which it is installed. The zone is defined with reference to the seating reference point (see §571.3). (For purposes of the figures, “H Point” means seating reference point.) A tether anchorage may be recessed in the seat back, provided that it is not in the strap wrap-around area at the top of the vehicle seat back. For the area under the vehicle seat, the forwardmost edge of the shaded zone is defined by a vertical plane 120 mm rearward of the “H Point,” as shown in figure 3 to this section.

S6.2.2.1 Subject to S6.2.2.2, for vehicles with adjustable or removable head restraints or no head restraints, the tether anchorage to which a tether hook attaches must be located outside the zone created by a 325 mm radius sphere with its center on the R-point and truncated horizontally at 230 mm below the sphere's center as shown in figures 8 and 9 to this section.

S6.2.2.2 In the case of a vehicle that—

(a) Has a user-ready tether anchorage for which no part of the shaded zone shown in figures 4 through 7 and 10 to this section of the designated seating position for which the anchorage is installed is accessible without the need for folding the seatback (other than the head restraint) or removing a seating component of the vehicle; and

(b) Has a tether strap routing device that is—

(1) Not less than 65 mm behind the torso line for that seating position, in the case of a flexible routing device or a deployable routing device, measured horizontally and in a vertical longitudinal plane; or

(2) Not less than 100 mm behind the torso line for that seating position, in the case of a fixed rigid routing device, measured horizontally and in a vertical longitudinal plane, the part of that anchorage that attaches to a tether hook may, at the manufacturer's option (with said option selected prior to, or at the time of, certification of the vehicle) be located outside that zone.

(c) The measurement of the location of the flexible or deployable routing device described in S6.2.2.2(b)(1) is made with SFAD 2 properly attached to the lower anchorages. A 40 mm wide nylon tether strap is routed through the routing device and attached to the tether anchorage in accordance with the written instructions required by S12 of this standard. The forwardmost contact point between the strap and the routing device must be within the stated limit when the tether strap is flat against the top surface of the SFAD and tensioned to 55 to 65 N. In seating positions without lower anchorages of a child restraint anchorage system, the SFAD 2 is held with its central lateral plane in the central vertical longitudinal plane of the seating position. The adjustable anchorage attaching bars of the SFAD 2 are replaced by spacers that end flush with the back surface of the SFAD 2.

S6.3 Strength requirements for tether anchorages. (a) When tested in accordance with S8, the tether anchorage must not separate completely from the vehicle seat or seat anchorage or the structure of the vehicle.

(b) Provisions for simultaneous and sequential testing:

(1) In the case of vehicle seat assemblies equipped with more than one tether anchorage, the force referred to in this S6.3 may, at the agency's option, be applied simultaneously to each of those tether anchorages. However, that force may not be applied simultaneously to tether anchorages for any two adjacent seating positions whose midpoints are less than 400 mm apart, as measured in accordance with S6.3(b)(i) and (ii) and figure 20 to this section.

(i) The midpoint of the seating position lies in the vertical longitudinal plane that is equidistant from vertical longitudinal planes through the geometric center of each of the two lower anchorages at the seating position. For those seating positions that do not provide lower anchorages, the midpoint of the seating position lies in the vertical longitudinal plane that passes through the SgRP of the seating position.

(ii) Measure the distance between the vertical longitudinal planes passing through the midpoints of the adjacent seating positions, as measured along a line perpendicular to the planes.

(2) A tether anchorage of a particular child restraint anchorage system will not be tested with the lower anchorages of that anchorage system if one or both of those lower anchorages have been previously tested under this standard.

S6.4 Marking and conspicuity requirements for tether anchorages. Vehicles subject to Standard No. 225 (this section) shall meet S6.4 according to the phase-in schedule specified in S13 of this standard.

(a) For each tether anchorage installed pursuant to S4 of this standard, there shall be a permanent marking that:

(1) Consists of one of the pictograms shown in figure 25 to this section that is not less than 20 mm in height;

(2) Except for vehicles that use a routing device per S6.2.2.2, the center of the pictogram in the longitudinal direction must be in the vertical longitudinal plane that passes through the center of the tether anchorage bar (± half of the tether anchorage length), as shown in figure 26 (Left) to this section; or the center of the pictogram in the lateral direction must be in the horizontal lateral plane that passes through the center of the tether anchorage bar (± half of the pictogram height), as shown in figure 26 (right) to this section.

(3) The nearest edge of the marking shall be located not more than 100 mm away from the tether anchorage bar as shown in figure 27 to this section. No other attachment feature to secure occupant items (i.e., cargo hooks or similar) shall be nearer to the marking than the distance from the marking to the tether anchorage. Vehicles with routing devices per S6.2.2.2 may use tags attached to the routing device.

(b) The tether anchorage bar may be covered by a cap or cover that is removable without the use of any tool, provided that the cap or cover is permanently labeled with a marking meeting the requirements of S6.4(a)(1). If the cap or cover is permanently attached to the vehicle, the tether anchorage is not required to be separately marked. If the cap or cover is not permanently attached to the vehicle, the tether anchorage must also be marked with the symbol meeting S6.4(a)(1) through (3).

(c) For vehicles that have a cargo cover that needs to be moved or removed to access the tether anchorages, the cargo cover must be permanently marked with the symbol meeting S6.4.1(a)(1) of this standard for each tether anchorage that is accessible under the cargo cover. Tether anchorages under the cargo cover must also be marked per S6.4(a).

If the cap or cover is permanently attached to the vehicle, the lower anchorage bars are not required to be separately marked with the pictogram. If the cap or cover is not permanently attached to the vehicle, the lower anchorage bars must also be marked with the symbol meeting S9.5.2(a)(1) through (4).

* * * *

S11. Test procedures. Each vehicle shall meet the requirements of this standard when tested according to the following procedures. Where a range of values is specified, the vehicle shall be able to meet the requirements at all points within the range.

(a) Strength requirements —(1) Forward force direction. Place SFAD 2 in the vehicle seating position and attach it to the two lower anchorages of the child restraint anchorage system. Do not attach the tether anchorage. A rearward horizontal force of 135 ±15 N is applied to the center of the lower front crossbar of SFAD 2 to press the device against the seat back as the fore-aft position of the rearward extensions of the SFAD is adjusted to remove any slack or tension. Apply a preload force of 500 N horizontally and in the vertical centerline of the SFAD 2 at point X. Increase the pull force as linearly as practicable to a full force application of 11,000 N in not less than 24 seconds and not more than 30 seconds and maintain at an 11,000 N level for 1 second.

(2) Lateral force direction. Place SFAD 2 in the vehicle seating position and attach it to the two lower anchorages of the child restraint anchorage system. Do not attach the tether anchorage. A rearward force of 135 ±15 N is applied to the center of the lower front crossbar of SFAD 2 to press the device against the seat back as the fore-aft position of the rearward extensions of the SFAD is adjusted to remove any slack or tension. Apply a preload force of 500 N horizontal and perpendicular to the longitudinal centerline of the SFAD 2 at point X of the test device. Increase the pull force as linearly as practicable to a full force application of 5,000 N in not less than 24 seconds and not more than 30 seconds and maintain at a 5,000 N level for 1 second.

(b) Clearance angle. The seat back angle, if adjustable, is set at the manufacturer's nominal design seat back angle. If the position is not specified, set the seat back at the first detent rearward of 25° from the vertical. Remove or open any lower anchorage cover, if present, to expose the lower anchorage. To measure clearance angle, attach the clearance angle tool to the lower anchorage and apply a vertical force of 67 N (15 lbf) to the tool. Measure the angle (with respect to the horizontal) of the tool while the force is being applied.

(c) Anchorage depth. The seat back angle, if adjustable, is set at the manufacturer's nominal design seat back angle. If the position is not specified, set the seat back at the first detent rearward of 25° from the vertical. To measure the anchorage depth, subtract 30 degrees from the measured seat pan angle to calculate the view angle. With the anchorage depth tool ( see figure 28 to this section) on a flat surface, adjust the view bar to read the view angle. Slide the zeroing strip along the view bar so that it is barely touching the top of the depth tool hook. Move the view bar forward, so the end of the zeroing strip is aligned with the zero-scribe line. For hidden anchorages, slide the anchorage depth tool so that it reads 0 mm at the rear edge of the slider. For visible anchorages, align the depth gauge to 25 mm so that negative values can be read. Attach the depth tool centered to the lower anchorage. Adjust the depth tool base to be within ±2 degrees of the view angle (30 degrees minus seat pan angle) to set the tool-parallel to the seat pan angle. Move the entire slider bar forward until the zeroing strip contacts the vehicle seat back or any other vehicle part.

S12. Written instructions. Vehicles subject to Standard No. 225 (this section) shall meet the written instruction requirements specified in either S12.1 or S12.2 according to the phase-in schedule specified in S13.

S12.1 Written instructions shall:

EHS Monthly Round Up - February 2026

EHS Monthly Round Up - February 2026

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

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

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

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

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

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

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

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

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

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

Colorado adds landfill methane emission regulation

Effective date: February 14, 2026

This applies to: Open and closed municipal solid waste landfills

Description of change: The Colorado Air Quality Control Commission added Regulation 31, which establishes new emission control and monitoring requirements for municipal solid waste landfills. Applicability is based on the landfill’s amount of waste it holds and methane emissions.

Significant changes implemented by Regulation 31 include:

  • Establishing a stricter emission control threshold than federal standards so that more landfills must install gas collection and control systems,
  • Mandating closed landfills with emission combustion devices to install biofilters when the devices are removed,
  • Expanding the methane monitoring requirements (allowing additional monitoring tools for identifying large emission sources) and allowing alternative monitoring technologies for periodic monitoring, and
  • Phasing in a ban on open flares to replace them with enclosed flares.

This applies to: Water right holders who divert more than 10 acre-feet per year

Description of change: The California State Water Resources Control Board (SWRCB) updated the Water Measurement and Reporting Regulation (SB 88) with changes primarily affecting reporting requirements, such as:

  • Requiring diverters to submit data to the SWRCB using a template or the online reporting platform CalWATRS,
  • Requiring large diverters to submit data to CalWATRS instead of posting it to any public website,
  • Requiring diverters to identify and report measurement locations, and
  • Requiring diverters to submit their measurement methodologies.

Updated measuring and reporting requirements take effect on October 1, 2026.

EPA proposes electronic-only hazardous waste manifests
2026-03-06T06:00:00Z

EPA proposes electronic-only hazardous waste manifests

On March 5, 2026, the Environmental Protection Agency (EPA) issued a proposed rule to end the use of paper hazardous waste manifests and require waste handlers to use electronic manifests on the Hazardous Waste Electronic Manifest (e-Manifest) System to track all shipments of hazardous waste regulated under the Resource Conservation and Recovery Act (RCRA).

What are the proposed changes?

EPA proposes to “sunset” (i.e., phase out) the use of paper manifests and shift to using only electronic manifests (either fully electronic or hybrid) to track RCRA hazardous waste shipments.

The sunset compliance date would be 2 years from the publication date of a final rule. On and after the sunset compliance date, EPA would no longer accept paper hazardous waste manifests (image-only and data-plus-image submission types). In other words, regulated waste handlers would have to use fully electronic or hybrid manifests on the e-Manifest System for all hazardous waste shipments initiated on and after the sunset compliance date.

Who would be impacted?

The proposed rule would affect waste handlers involved in manifesting hazardous waste, including:

  • Generators,
  • Transporters, and
  • Receiving facilities.

Many of the proposed changes would align RCRA regulations with the shift to electronic-only manifesting and with the 2024 e-Manifest Third Rule’s changes. The proposed rule also contains technical corrections to import and export regulations.

Additionally, EPA’s proposed rule would add requirements for:

  • Very small quantity generators (VSQGs) managing episodic events,
  • RCRA hazardous waste transporters,
  • Healthcare facilities and reverse distributors subject to RCRA’s hazardous waste pharmaceutical requirements,
  • Certain polychlorinated biphenyl (PCB) waste generators,
  • PCB waste transporters, and
  • Hazardous waste treatment or storage facilities with standardized RCRA permits.

Examples of these requirements include:

  • Mandating specific waste handlers to register with the e-Manifest System;
  • Requiring VSQGs, healthcare facilities, and reverse distributors to submit data corrections to the e-Manifest System within 30 days of a request from EPA or an authorized state; and
  • Requiring hazardous waste generators and PCB waste generators to identify brokers on the manifest.

EPA will accept public comments on the proposed rule (Docket ID No. EPA-HQ-OLEM-2025-3456) through May 4, 2026.

Key to remember: EPA proposes to end the use of paper manifests and require waste handlers to use electronic manifests to track all RCRA hazardous waste shipments.

EPA temporarily extends 2021 MSGP coverage
2026-03-04T06:00:00Z

EPA temporarily extends 2021 MSGP coverage

The Environmental Protection Agency (EPA) has issued an administrative continuance of the 2021 Multi-Sector General Permit (MSGP) and a No Action Assurance memorandum for industrial stormwater discharges regulated under the National Pollutant Discharge Elimination System.

The 2021 MSGP expired on February 28, 2026. However, because EPA hasn’t reissued a new permit to replace the expired permit, the 2021 MSGP remains in effect for facilities previously covered. Additionally, the No Action Assurance allows facilities without previous coverage to discharge industrial stormwater in compliance with the 2021 MSGP.

Who’s affected?

Facilities are required to obtain MSGPs for stormwater discharges from industrial activities in areas where EPA is the permitting authority, including:

  • Existing facilities (those that had active coverage under the 2021 MSGP), and
  • New facilities (those that didn’t obtain coverage under the 2021 MSGP before it expired).

What do existing facilities do?

The administrative continuance automatically applies to existing facilities that were actively covered by the 2021 MSGP before it expired. The facility’s coverage status should show “Admin. Continued” in the NPDES eReporting Tool (NeT-MSGP).

Facilities will remain covered by the 2021 MSGP until EPA issues a new MSGP and the facilities obtain coverage under the new MSGP. Until then, existing facilities should continue to comply with the 2021 MSGP requirements.

EPA will provide further guidance on renewing coverage when it issues the new MSGP.

What do new facilities do?

New facilities can’t obtain coverage under the MSGP until EPA issues a new permit. However, EPA issued a memorandum on February 27, 2026, establishing a No Action Assurance. The agency won’t take enforcement action against new facilities for unpermitted stormwater discharges if the facilities meet specific conditions.

The No Action Assurance extends from March 1, 2026, to the new MSGP’s effective date.

Applicability

EPA’s No Action Assurance applies to facilities that:

  • Discharge stormwater on or after March 1, 2026 (but before the new MSGP’s effective date); and
  • Didn’t submit a Notice of Intent (NOI) for coverage under the 2021 MSGP before its expiration on February 28, 2026.

The assurance doesn’t apply to existing facilities that started stormwater discharges before February 28, 2026, without obtaining 2021 MSGP coverage.

Conditions

To be covered by the No Action Assurance, new facilities have to:

  • Meet the 2021 MSGP eligibility criteria,
  • Submit an NOI form (Appendix G of the MSGP) via msgp@epa.gov to notify EPA of their intention to operate according to all applicable 2021 MSGP requirements before discharging industrial stormwater, and
  • Comply with all applicable 2021 MSGP regulations, such as:
    • Developing and implementing a Stormwater Pollution Prevention Plan,
    • Installing and maintaining stormwater controls, and
    • Conducting site inspections and monitoring.

What’s next?

Once EPA issues the new MSGP, facilities planning to continue industrial stormwater discharges must submit a new NOI through Net-MSGP within 90 days of the new MSGP’s effective date to obtain coverage under the new MSGP.

EPA provides guidance for existing and new facilities on its “Administrative Continuance of EPA’s 2021 MSGP” webpage.

Key to remember: EPA has temporarily extended coverage under the 2021 MSGP for industrial stormwater discharges until the agency issues a new general permit.

EPA extends 2025 GHG reporting deadline
2026-02-27T06:00:00Z

EPA extends 2025 GHG reporting deadline

The Environmental Protection Agency (EPA) finalized a rule on February 27, 2026, extending the submission deadline for the 2025 annual greenhouse gas (GHG) report from March to October 2026.

Who’s impacted?

The final rule applies to facilities regulated by the GHG Reporting Program (GHGRP) at 40 CFR Part 98. Generally, the GHGRP’s annual reporting requirement applies to three types of reporters:

  • Large industrial sources of GHG emissions (that directly emit 25,000 or more metric tons of carbon dioxide equivalent (CO2e) per year);
  • Fuel and industrial gas suppliers (whose products would result in 25,000 or more metric tons of CO2e of GHG emissions per year if released, combusted, or oxidized); and
  • CO2 injection facilities (that receive 25,000 or more metric tons of CO2 for injection).

What’s the change?

The final rule extends the submission deadline for the reporting year (RY) 2025 annual GHG report from March 31, 2026, to October 30, 2026. The delay applies only to RY 2025.

EPA explains in the final rule that delaying the submission deadline for the RY 2025 GHG report gives the agency time to take final action on the proposed revisions to the GHGRP (published in September 2025).

What does the GHG report cover?

The GHGRP requires facilities to report GHG data and other related information covering the previous calendar year.

The subparts under Part 98 contain the reporting requirements, and regulated facilities must report emissions for all applicable source categories. Reporters must use specific methods to calculate GHG emissions, which are detailed in the regulations; they can usually choose from a collection of methods.

Key to remember: EPA’s final rule delays the submission deadline for the 2025 annual GHG report from March to October 2026.

EPA scraps Endangerment Finding, GHG emission standards: What you need to know
2026-02-25T06:00:00Z

EPA scraps Endangerment Finding, GHG emission standards: What you need to know

“Road Closed Ahead.” That’s the sign that now stands at the entrance of the regulatory road leading to the federal greenhouse gas (GHG) emission standards for vehicle and engine manufacturers.

The Environmental Protection Agency (EPA) finalized a rule on February 18, 2026, to rescind the 2009 Endangerment Finding and repeal all GHG emission standards for new motor vehicles and motor vehicle engines. The final rule applies to vehicles and engines of model years 2012 to 2027 and beyond.

This overview will help you navigate EPA’s final rule that puts GHG emission requirements for vehicles in the rearview mirror.

What does this mean?

Manufacturers (including importers) of new motor vehicles and motor vehicle engines will no longer have future obligations to measure, control, report, or comply with federal GHG emission standards.

Specifically, the final rule removes the requirements for controlling GHG emissions, which include:

  • Emission standards;
  • Test procedures;
  • Averaging, banking, and trading requirements;
  • Reporting requirements; and
  • Fleet-average emission requirements.

Additionally, the final rule eliminates off-cycle credits for manufacturers that added certain technologies to their vehicles and engines (like waste heat recovery) and EPA’s incentives for manufacturers to install a start-stop system (which automatically shuts off a vehicle’s engine when idling).

When do the changes apply?

The final rule takes effect on April 20, 2026. However, a legal challenge has already been brought against the rulemaking, and more litigation is likely.

It’s important to keep an eye on the status of the rule. Legal challenges could result in changes to the rule, such as delaying its effective date.

What regulations were removed?

The final rule repeals all GHG emission regulations in 40 CFR:

Why did EPA remove the standards?

The road to reversal begins in 2009. That’s when EPA issued two findings: the Endangerment Finding and the Cause or Contribute Finding. Collectively, these findings are referred to as the 2009 Endangerment Finding. The agency used the 2009 Endangerment Finding as the legal basis under Section 202(a) of the Clean Air Act (CAA) to regulate GHG emissions from new motor vehicles and motor vehicle engines based on global climate change concerns.

However, upon reconsideration, EPA no longer believes that it has the statutory authority under Section 202(a) of the CAA to regulate GHG emissions from new motor vehicles and motor vehicle engines in response to global climate change concerns. The agency bases its determination on three factors:

  • EPA concludes that the best reading of Section 202(a) of the CAA authorizes the agency to regulate air pollution that threatens to endanger health and welfare through local and regional exposure. Therefore, the CAA doesn’t give EPA the authority to regulate GHG emissions based on global climate change concerns. The agency conducted the “best reading” by using standard interpretation principles and being informed by the Supreme Court’s overturning of “Chevron deference” in Loper Bright Enterprises v. Raimondo (2024).
  • EPA lacks the congressional authorization required to regulate GHG emissions based on global climate change concerns. The agency determined that the major questions doctrine (i.e., federal agencies may not decide issues of major national significance without clear authorization granted by Congress) applies to the Endangerment Finding and that Congress doesn’t give EPA the authority under Section 202(a) of the CAA to decide a national policy response to global climate change concerns.
  • The GHG emission regulations don’t and can’t have a meaningful impact on the identified health and welfare dangers that the Endangerment Finding attributed to global climate change. EPA based this conclusion on the results of climate impact modeling that the public submitted in response to the proposed rule and on the agency’s modeling analysis used to evaluate the submissions.

By rescinding the Endangerment Finding, EPA has no legal basis to regulate GHG emissions from new motor vehicles and motor vehicle engines. Accordingly, the final rule also repeals all GHG emission standards for light-, medium-, and heavy-duty vehicles and heavy-duty engines.

Key to remember: EPA’s final rule eliminates the 2009 Endangerment Finding and the related GHG emission requirements for on-highway vehicles and vehicle engines.

EPA repeals stricter Mercury and Air Toxics Standards for coal-, oil-fired power plants
2026-02-24T06:00:00Z

EPA repeals stricter Mercury and Air Toxics Standards for coal-, oil-fired power plants

On February 24, 2026, the Environmental Protection Agency (EPA) published a final rule repealing the 2024 amendments made to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs). It’s also referred to as the Mercury and Air Toxics Standards (MATS) for power plants.

Effective April 27, 2026, this rule (2026 Final Rule) repeals stricter compliance requirements made to the MATS rule in May 2024 (2024 Final Rule) and reverts them to the less stringent standards established by the 2012 MATS Rule.

Who’s affected?

The rule applies to power plants with coal- and oil-fired EGUs subject to the NESHAP (40 CFR 63 Subpart UUUUU).

What are the changes?

The final rule repeals these 2024 amendments:

  • The revised filterable particulate matter (fPM) emission standard and corresponding total and individual non-metal hazardous air pollutant (HAP) metal standards for existing coal-fired EGUs (reverting to the 2012 MATS Rule requirements);
  • The revised compliance demonstration requirements for all EGUs to install continuous emission monitoring systems (CEMS) for fPM emissions and the adjusted quality assurance (QA) criteria (reverting to the previous standard, allowing EGUs to choose from three compliance demonstration methods); and
  • The revised mercury (Hg) emission standard for lignite-fired EGUs (reverting to the 2012 MATS Rule limit).

The 2026 Final Rule also reinstates the low-emitting EGU (LEE) program for fPM and non-Hg HAP metals. The LEE program requires less frequent stack testing for sources with emissions below 50 percent of the corresponding limit for 3 consecutive years.

Further, EPA’s final rule updates the fPM sampling requirements for EGUs that demonstrate compliance with a PM CEMS. These units must collect either a minimum catch of 6.0 milligrams or a minimum sample volume of 4 dry standard cubic meters (dscm) per test run. EGUs demonstrating compliance using other methods must collect a lower minimum sample volume of 1 dscm per PM test run.

Compliance requirement2024 Final Rule2026 Final Rule
fPM emission limit for existing coal-fired EGUs0.010 pounds per million British thermal units of heat input (lb/MMBtu)0.030 lb/MMBTu
fPM emission compliance demonstration for all coal-and oil-fired EGUsEGUs must use PM CEMS.EGUs may use:
  • Quarterly stack testing,
  • PM continuous parametric monitoring systems, or
  • PM CEMS.
Hg emission limit for existing lignite-fired EGUs1.2 pounds per trillion British thermal units of heat input (lb/TBtu)4.0 lb/TBtu
Key to remember: EPA’s final rule repeals the stricter emission limits set by the 2024 amendments to the Mercury and Air Toxics Standard for coal- and oil-fired power plants.

PFAS, pretreatment, and biosolids: The growing challenge for water permitting
2026-02-20T06:00:00Z

PFAS, pretreatment, and biosolids: The growing challenge for water permitting

Per and polyfluoroalkyl substances (PFAS) pose one of the most urgent and complex challenges for wastewater systems in the United States. As federal agencies reconsider their regulatory strategies and states impose their own standards, publicly owned treatment works (POTWs) and the industries that discharge to them face increasing pressure to control PFAS at the source. These pressures affect pretreatment permits, industrial dischargers, and biosolids management, forming a rapidly evolving compliance landscape. Recent federal assessments and state actions show that PFAS in wastewater and biosolids is no longer a distant regulatory issue. It is a primary driver shaping future POTW permitting.

PFAS in POTW systems: A problem that starts upstream

PFAS enter POTWs through a mix of industrial wastewater, landfill leachate, household products, and consumer goods. Because PFAS are persistent and resistant to conventional treatment, they pass through biological processes largely unchanged. This means industrial contributors sending PFAS to a POTW can cause downstream compliance problems, even at low concentrations. EPA has emphasized that the best way to manage PFAS in wastewater is to prevent the chemicals from entering treatment systems in the first place, placing new attention on upstream industrial sources.

EPA’s 2025 trajectory indicates broader PFAS rulemaking is coming under several environmental statutes, including the Clean Water Act (CWA), Resource Conservation and Recovery Act, and Safe Drinking Water Act, although the federal landscape remains in flux. Still, agencies agree on one point: pretreatment programs will be an essential component of PFAS control.

Pretreatment permits: The first line of defense

Pretreatment permits regulate indirect dischargers, meaning industrial facilities that send wastewater to POTWs instead of directly to surface waters. These permits already manage pollutants that interfere with treatment or pass through into receiving waters. Now, PFAS has become a central focus.

States and POTWs are increasingly requiring:

  • PFAS monitoring in industrial wastewater,
  • Source identification surveys,
  • Product substitution or process changes,
  • Best management practices to reduce PFAS at the facility, and
  • Local limits or prohibitions on PFAS discharges

EPA’s PFAS strategy specifically encourages states and POTWs to deploy all available pretreatment authorities to control PFAS at the source. This approach aligns with statements from EPA representatives asserting that upstream controls are one of the most effective tools for preventing PFAS from entering wastewater systems.

Biosolids under scrutiny: The impact of PFAS

The PFAS problem does not end with liquid effluent. It extends into biosolids, the treated sewage sludge generated by POTWs. In 2025, EPA released a Draft Sewage Sludge Risk Assessment evaluating risks associated with PFOS and PFOA in biosolids applied to land. The assessment found potential human health risks under certain scenarios when biosolid concentrations exceeded 1 part per billion. Although EPA emphasized the assessment is not a regulatory standard, many states immediately treated the value as a de facto limit for biosolid land application.

This rapid adoption has created a challenging environment for POTWs. Unless PFAS inputs from industrial sources are reduced, biosolid PFAS levels remain high, limiting disposal options such as:

  • Agricultural land application,
  • Composting,
  • Surface disposal,
  • Landfilling, and
  • Incineration

Some states have already implemented bans or strict standards on biosolid land application due to PFAS concerns.

Regulatory uncertainty adds pressure

EPA’s PFAS regulatory posture has shifted several times. In 2025, EPA announced its intent to rescind certain PFAS drinking water designations while maintaining standards for PFOS and PFOA, signaling continued reassessment of its overall PFAS approach. These actions underscore the unsettled nature of federal rulemaking.

Meanwhile, the 2021 PFAS Strategic Roadmap and its subsequent progress updates outline multiple forthcoming actions under the CWA, including potential effluent limitation guidelines (ELGs) for PFAS manufacturers and metal finishers. These ELGs, if finalized, would apply to industrial direct and indirect dischargers and shape pretreatment standards nationwide. Yet, as of early 2026, EPA has not finalized technology based effluent limits for PFAS nor established national PFAS biosolids requirements, leaving states to fill the regulatory void.

What POTWs and industrial users should do now

Despite uncertainty, actions today can reduce long term liability:

  • Conduct PFAS source identification at industrial users,
  • Require PFAS monitoring in pretreatment permits,
  • Develop local limits where state guidance is emerging,
  • Engage with industrial facilities early on substitution and pollution prevention,
  • Evaluate biosolids PFAS levels to assess disposal risks, and
  • Participate in state rulemaking to anticipate new limits

POTWs should also coordinate with state environmental agencies, which continue to implement PFAS restrictions independent of federal action.

Pretreatment programs and biosolids management are becoming central to U.S. PFAS compliance. POTWs sit at the intersection of regulatory expectations, industrial discharges, and community concerns. While federal PFAS rules remain in development, state actions and EPA’s strategic direction make one fact clear: controlling PFAS at the source is essential.

Key to remember: For both industrial users and POTWs, proactive PFAS management is no longer optional. It is a core element of future permitting, planning, and risk reduction.

Expert Insights: States take the lead as federal environmental rules pull back

Recent changes in federal environmental policy have created uncertainty for regulated industries. When federal agencies slow rulemaking, reduce enforcement, or narrow requirements, states often step in. As a result, states are taking a stronger role in setting environmental rules, especially on climate change, air quality, and environmental justice.

This shift is changing how industrial facilities understand and manage regulatory risks.

States as environmental policy leaders

Several states have moved to the front of environmental policymaking. California is the most well-known example. Through the California Air Resources Board (CARB), the state enforces air and climate rules that go beyond federal standards. These include strict vehicle emissions limits and greenhouse gas controls for industrial sources. Because California’s economy is so large, its rules often shape compliance decisions across the country.

Other states are following similar paths. For example, New York’s Climate Leadership and Community Protection Act sets clear, enforceable emissions-reduction goals. It also requires agencies to consider climate and environmental justice impacts during permitting. Washington has adopted a cap-and-invest program that limits carbon emissions from major sources and fuel suppliers.

Growing impacts on industrial facilities

For industrial operators, state-led regulation adds complexity and risk. Companies with facilities in multiple states may face very different rules, timelines, and reporting requirements. Meeting federal standards alone may no longer be enough.

Facilities can still fall out of compliance with state rules covering air emissions, water discharges, waste management, or community impacts. These differences can affect permitting schedules, capital planning, and long-term site decisions.

State enforcement and local focus

State enforcement is often more focused and, in many cases, more stringent than federal enforcement. Many states are increasing inspections and placing greater emphasis on environmental justice.

Facilities located near overburdened or historically impacted communities may face closer review, even when federal enforcement activity is limited.

Practical strategies for compliance

To operate successfully in this environment, companies need a proactive approach. Tracking state regulatory changes is essential, since states often move faster than federal agencies. Building compliance programs around the most stringent applicable rules can reduce long-term risk.

Early engagement with state regulators and local communities can also make a difference. Open communication can improve relationships, reduce conflict, and support smoother permitting outcomes.

For industrial facilities, success now depends less on watching Washington and more on understanding the growing influence of state capitals.

EPA reverses Endangerment Finding, scraps GHG emission standards for vehicles

EPA reverses Endangerment Finding, scraps GHG emission standards for vehicles

The Environmental Protection Agency (EPA) published a final rule on February 18, 2026, to rescind the 2009 Endangerment Finding and repeal all federal greenhouse gas (GHG) emission standards for:

  • On-highway light-, medium-, and heavy-duty vehicles; and
  • On-highway heavy-duty vehicle engines.

The final rule takes effect on April 20, 2026, and applies to vehicles and engines of model years 2012 to 2027 and beyond.

What are the changes?

Manufacturers (including importers) of new motor vehicles and motor vehicle engines no longer have to measure, report, or comply with federal GHG emission standards. The final rule removes all GHG emission regulations in 40 CFR:

  • Parts 85, 86, and 600 (light- and medium-duty vehicles);
  • Part 1036 (heavy-duty vehicle engines); and
  • Part 1037 (heavy-duty vehicles).

The final rule also eliminates:

  • All off-cycle credits for the addition of certain technological features (e.g., high-efficiency exterior lighting, waste heat recovery, and active seat ventilation); and
  • EPA’s incentives for manufacturers to add a start-stop system (which automatically shuts off a vehicle’s engine during idling).

What doesn’t change?

EPA’s following regulations remain in effect for new motor vehicles and vehicle engines:

  • Criteria pollutant and air toxic measurement and standards,
  • Corporate Average Fuel Economy testing, and
  • Associated fuel economy labeling requirements.

About the 2009 Endangerment Finding

In 2009, EPA issued two findings: the Endangerment Finding and the Cause or Contribute Finding. Collectively, these findings are referred to as the 2009 Endangerment Finding. The agency used the 2009 Endangerment Finding as the legal basis to regulate GHG emissions from new motor vehicles and vehicle engines under Section 202(a) of the Clean Air Act.

EPA regulated GHG emissions from new motor vehicles and vehicle engines through:

  • Emission standards and related requirements, and
  • Engine and vehicle certification requirements.

However, upon reconsideration, EPA stated that it no longer believes it has the statutory authority under Section 202(a) of the Clean Air Act to regulate GHG emissions from new motor vehicles and vehicle engines. Therefore, the agency has simultaneously rescinded the 2009 Endangerment Finding and repealed the related federal GHG emission regulations.

Key to remember: EPA's final rule eliminates the 2009 Endangerment Finding and the related GHG emission requirements for on-highway vehicles and vehicle engines.

EPA delays CCR management unit reporting, related requirements

EPA delays CCR management unit reporting, related requirements

The Environmental Protection Agency (EPA) issued a final rule that extends the deadlines for Facility Evaluation Reports (FERs) required for active and inactive coal combustion residuals (CCR) facilities. The final rule also delays compliance deadlines for related requirements that apply to CCR facilities with CCR management units (CCRMUs).

Who’s impacted?

The final rule applies to:

  • Active CCR facilities, and
  • Inactive CCR facilities with inactive surface impoundments (i.e., legacy CCR surface impoundments).

The 2024 Legacy Final Rule (40 CFR Part 257 Subpart D) requires active CCR facilities and legacy CCR surface impoundments to submit FER Part 1 and FER Part 2, identifying any CCRMUs of 1 ton or more on-site. CCRMUs include previously unregulated CCR surface impoundments and landfills that closed before October 19, 2015, as well as inactive CCR landfills.

Additionally, the 2024 Legacy Final Rule requires facilities with CCRMUs to:

  • Establish a website to publicize the facility’s CCR information;
  • Conduct groundwater monitoring activities (specifically, install a groundwater monitoring system, develop a sampling and analysis plan, collect independent samples, and perform detection and assessment monitoring);
  • Submit the initial annual groundwater monitoring and corrective action (GWMCA) report; and
  • Comply with closure and post-closure care obligations.

What are the changes?

EPA’s final rule extends compliance deadlines for the following standards:

Compliance requirement(s)2024 Legacy Final Rule deadline2026 final rule new deadline
Establish CCR websiteFebruary 9, 2026February 9, 2027
Submit FER Part 1February 9, 2026February 9, 2027

Expiring TSCA CBI claims: How to request an extension
2026-02-12T06:00:00Z

Expiring TSCA CBI claims: How to request an extension

How do businesses keep confidential information “off the record”? Companies that are required to report on federally regulated chemical substances may soon face this question, as the first round of confidential business information (CBI) claims starts expiring in June 2026.

Thankfully, the Environmental Protection Agency (EPA) has answered how to keep CBI off the record. On January 6, 2026, the agency published in the Federal Register the process to request extensions of expiring CBI claims for information submitted under the Toxic Substances Control Act (TSCA).

Here’s what you need to know.

CBI extension request process

Businesses that seek to extend a CBI claim beyond its expiration date must submit an extension request. The Federal Register notice describes the following general process:

1. EPA notifies the entity of an expiring CBI claim.

The agency will publish a list of TSCA submissions with expiring CBI claims on the Confidential Business Information Under TSCA (TSCA CBI) website at least 60 days before the claims expire.

EPA will also notify submitters directly through its online Central Data Exchange (CDX). Verify that your company’s contact information on CDX is updated!

Submitters with CBI claims for specific chemical identities should reference the TSCA Chemical Substance Inventory (column EXP) to confirm expiration dates.

2. The entity submits an extension request.

The extension request for an expiring CBI claim includes:

  • A certified supporting statement confirming the four assertions at 40 CFR 703.5(a), and
  • Answers to EPA’s substantiation questions.

EPA lists the general questions that apply to all CBI claims at 703.5(b)(3). Additional questions at 703.5(b)(4) apply to entities claiming CBI for specific chemical identities.

Businesses must submit the extension through EPA’s CDX at least 30 days before the CBI claim expires. The agency is currently developing a new application on CDX for submitting extension requests, which it plans to launch before CBI claims begin expiring in June 2026.

If there’s a delay, EPA will notify submitters on the TSCA CBI website. Additionally, the agency won’t publicize any information from expiring CBI claims until businesses have the opportunity to submit extension requests and the agency reviews them.

3. EPA reviews the extension request.

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

If the agency denies the extension request, the information in the CBI claim can be publicized once the claim expires. EPA will notify submitters of denied claims through CDX at least 30 days before it plans to disclose the information.

Expiring CBI claims: What are the options?

Regulated entities have three ways to address expiring CBI claims:

  • If you choose to maintain the CBI claim, submit the extension request to EPA.
  • If you decide not to renew the CBI claim, you can either:
    • Withdraw the CBI claim through CDX, or
    • Allow the CBI claim to expire (i.e., take no action).

Keep in mind that if you withdraw a CBI claim or allow it to expire, EPA can publicize this information without notifying you beforehand.

Who’s impacted?

The CBI extension request process applies to companies that have made CBI claims under TSCA on or after June 22, 2016.

The Frank R. Lautenberg Chemical Safety for the 21st Century Act (signed into law on June 22, 2016) made amendments to TSCA, including adding a 10-year expiration date to CBI claims.

Key to remember: EPA established the process for entities to request extensions of expiring CBI claims for information submitted under TSCA.

Common errors companies make when submitting air emissions inventories

Common errors companies make when submitting air emissions inventories

Submitting accurate air emissions inventories (AEIs) is essential for regulatory compliance, public transparency, and long-term environmental planning. Yet companies routinely make mistakes that delay approvals, trigger enforcement, or compromise data quality. Many of these errors stem from misunderstanding the reporting rules, such as the Environmental Protection Agency's (EPA’s) Air Emissions Reporting Requirements (AERR) and Greenhouse Gas Reporting Program (GHGRP). Awareness of these pitfalls helps facilities avoid compliance failures and improve emission tracking systems.

Misunderstanding what must be reported

One of the most common errors is failing to understand which pollutants must be included. Under the AERR, states and delegated agencies must report annual emissions of criteria air pollutants, including sulfur dioxide, nitrogen oxides, volatile organic compounds, carbon monoxide, lead, particulate matter (PM2.5 and PM10), and ammonia. These pollutants drive national air quality planning and modeling.

However, many companies overlook hazardous air pollutants (HAPs). While past AERR rules made HAP reporting voluntary, EPA’s proposed revisions would require annual HAP reporting for many sources starting in 2027, significantly expanding reporting duties. Failing to include HAP data or assuming it's still voluntary is a growing compliance risk.

Greenhouse gases (GHGs) are another reporting blind spot. The GHGRP requires large emitters and certain suppliers to report carbon dioxide (CO2), methane, nitrous oxide, and other GHGs each year. Companies often assume GHG reporting applies only to the largest industries, yet thousands of facilities fall within the rule’s thresholds.

Using incorrect or incomplete emission calculations

Facilities often make calculation errors when converting raw activity data into emissions. Many rely on outdated emission factors or incomplete process data. EPA urges states and regulated entities to use standardized estimation guidance from the Air Emissions Inventory Improvement Program whenever possible. But companies may choose default factors without confirming they apply to the specific process, control efficiency, fuel type, or measurement method.

Under EPA’s proposed AERR revisions, if approved, the agency will require more detailed stack information, such as release point coordinates, exhaust parameters, control device data, and stack test results. Failure to collect these details early can lead to rushed estimates or missing data.

Misreporting source categories

Another major issue is misidentifying emission sources. The AERR distinguishes between point, nonpoint, mobile, and portable sources. Mislabeling a source may cause a facility to submit incomplete inventories or fail to meet the required reporting frequency. For example, point sources often require annual reporting, while nonpoint sources may follow triennial schedules.

Similarly, GHGRP reporting is broken into numerous subparts that define equipment types, fuel suppliers, industrial processes, and CO2 injection activities. Companies sometimes choose the wrong subpart or assume their process is exempt, leading to incomplete data submissions.

Incorrect use of thresholds and applicability

Both the AERR and GHGRP have emission-based thresholds. Companies frequently make errors when determining:

  • Whether they meet the AERR Type A point source criteria;
  • Whether they exceed GHGRP reporting thresholds (generally 25,000 metric tons CO2 equivalent annually); and
  • Whether HAP emissions exceed thresholds when HAP reporting is required by a state.

These mistakes usually occur when internal data systems lack consistent tracking or when actual emissions deviate from "potential to emit" estimates used in permitting.

Missing documentation and recordkeeping

EPA requires extensive documentation for emission calculations, monitoring methods, stack tests, control equipment operation, and assumptions. GHGRP rules include detailed monitoring, Quality Assurance/Quality Control (QA/QC), missing data, and record retention requirements. Under proposed AERR rules, companies would also need to submit performance test and evaluation data. Missing or incomplete records often lead to rejected inventories.

Failing to track regulatory updates

Both the AERR and GHGRP are undergoing major revisions. EPA’s proposed AERR updates aim to convert some triennial reporting to annual schedules, add HAP reporting, expand mobile source requirements, and require more detailed facility-level data. Meanwhile, the GHGRP is facing proposed cuts that would eliminate reporting requirements for many source categories while delaying petroleum and natural gas reporting until 2034.

Companies that rely on outdated guidance or assume reporting rules remain static are at risk of major compliance failures.

Improving AEI quality and compliance

Avoiding common errors begins with three fundamentals:

  • Use current regulatory guidance, emission factors, and calculation tools;
  • Maintain complete process data, stack test records, and QA/QC documentation; and
  • Assign knowledgeable staff to track AERR, GHGRP, and state-level changes.

Key to Remember: Accurate air emissions inventories play a crucial role in protecting public health, supporting air quality regulation, and demonstrating corporate responsibility. By understanding the most common pitfalls, companies can improve compliance and reduce costly reporting errors.

EHS Monthly Round Up - January 2026

EHS Monthly Round Up - January 2026

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

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

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

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

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

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

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

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

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

Erosion vs. sediment controls: Prevent stormwater pollution at the construction site
2026-01-30T06:00:00Z

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

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

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

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

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

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

Erosion controls vs. sediment controls

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

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

Erosion control examples include:

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

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

Examples of sediment controls are:

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

Common BMP examples

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

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

Use both types of BMPs

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

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

Check state and local requirements

Most states issue NPDES construction stormwater permits. Check the permit to confirm erosion control and sediment control requirements, as they may be more stringent at the state level.

Additionally, some local governments may impose requirements on construction sites. However, unless the local program is designated as a qualifying local program, compliance with local regulations may not mean that your construction site is compliant with EPA’s rules (and vice versa). Confirm with the local government whether additional requirements apply.

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

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

Dust collector to disposal: Understanding dust as a waste stream

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

When captured dust becomes a regulated waste

Under EPA regulations, most collected dust qualifies as a solid waste once it’s removed from a dust collector, hopper, or filter. And despite the name, “solid waste” doesn’t mean solid, benign, or harmless. It simply means a discarded material. At that point, facilities are expected to determine whether the dust is hazardous or non-hazardous under the Resource Conservation and Recovery Act (RCRA). This determination is based on what the dust contains, not how dusty it looks or how long it has been managed that way. Dust generated from metalworking, surface coatings, chemical processing, plastics, or specialty manufacturing can contain regulated constituents such as heavy metals or chemical residues. In these cases, facilities are required to make a waste determination using process knowledge, testing, or a combination of both. This step is often overlooked. Many companies assume that if dust has not caused problems in the past, it must be non-hazardous. Unfortunately, regulators do not accept assumptions as documentation. If there’s no clear waste determination on file, that alone can be cited during an inspection. Misclassifying dust can also have ripple effects. If collected dust is later found to be hazardous, the facility may face issues related to improper disposal, incorrect generator status, or even cleanup liability at the disposal site. What began as a routine housekeeping task can suddenly become a significant compliance issue.

Storage, Disposal, and the Risks of Getting It Wrong

Even when dust is correctly identified as non-hazardous, it still needs to be managed properly. Open containers, poor labeling, and inconsistent handling practices are common findings during inspections. These issues are often viewed as minor, but they can quickly escalate if dust is released, mixed with other waste streams, or stored improperly. Recycling adds another layer of complexity. Many facilities recycle metal dusts or other recoverable materials, which can be a smart environmental and economic decision. However, recyclable does not mean unregulated. Dust being recycled still needs to be stored safely, managed to prevent releases, and documented as legitimate recycling. Without proper controls, regulators may view the material as improperly managed waste. Outdoor storage creates additional risk. Dust stored outside, transferred outdoors, or tracked out of the building can easily become a stormwater concern. Even non-hazardous dust can be considered a pollutant if it migrates off-site during rain events. This is a frequent source of violations under stormwater permits and Stormwater Pollution Prevention Plans (SWPPP), especially when dust management isn’t addressed in the plan. Another common issue is mixing dust with general trash or other waste streams. Once mixed, otherwise manageable dust can become more difficult or impossible to classify correctly. This can complicate disposal, increase costs, and raise questions during audits or inspections. What makes dust especially challenging is that responsibility for it often falls into a gray area. Safety teams may assume environmental is managing disposal. Environmental teams may assume safety has already classified the material. When no one clearly owns the waste determination and disposal process, gaps are almost guaranteed. The most effective facilities treat dust as a waste stream that deserves the same attention as any other regulated material. They document waste determinations, define storage and labeling requirements, train employees on proper handling, and periodically revisit those determinations as processes change.

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