EPA Final Rule: Mississippi: Final Approval of State Underground Storage Tank Program Revisions

2024-01-18T06:00:00Z

The State of Mississippi (Mississippi or State) has applied to the Environmental Protection Agency (EPA) for final approval of revisions to its Underground Storage Tank Program (UST Program) under subtitle I of the Resource Conservation and Recovery Act (RCRA). Pursuant to RCRA, the EPA is taking direct final action, subject to public comment, to approve revisions to the UST Program. The EPA has reviewed Mississippi's revisions and has determined that these revisions satisfy all requirements needed for approval. In addition, this action also codifies the EPA's approval of Mississippi's revised UST Program and inCcorporates by reference those provisions of the State statutes and regulations that the EPA has determined meet the requirements for approval.

DATES:

This rule is effective March 18, 2024, published in the Federal Register January 18, 2024, page 3354.

(b)(4) Region 4 (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee): 61 Forsyth Street, SW, Atlanta, Georgia 30303-8960; Phone Number: (404) 562-9900.

§282.74 Mississippi State-Administered Program.

(a) History of the approval of Mississippi's program. The State of Mississippi (Mississippi or State) is approved to administer and enforce an underground storage tank (UST) program in lieu of the Federal program under subtitle I of the Resource Conservation and Recovery Act of 1976 (RCRA), as amended, 42 U.S.C. 6991 et seq. The State's Underground Storage Tank Program (UST Program), as administered by the Mississippi Department of Environmental Quality (MDEQ), was approved by EPA pursuant to 42 U.S.C. 6991c and part 281 of this chapter. EPA approved the Mississippi UST Program on June 11, 1990, and it was effective on July 11, 1990. A subsequent program revision was approved by EPA and became effective March 18, 2024.

(b) Enforcement authority. Mississippi has primary responsibility for administering and enforcing its federally approved UST Program. However, EPA retains the authority to exercise its corrective action, inspection, and enforcement authorities under sections 9003(h), 9005, and 9006 of subtitle I of RCRA, 42 U.S.C. 6991b(h), 6991d, and 6991e, as well as under any other applicable statutory and regulatory provisions.

(c) Retention of program approval. To retain program approval, Mississippi must revise its approved UST Program to adopt new changes to the Federal subtitle I program which make it more stringent, in accordance with section 9004 of RCRA, 42 U.S.C. 6991c, and 40 CFR part 281, subpart E. If Mississippi obtains approval for revised requirements pursuant to section 9004 of RCRA, 42 U.S.C. 6991c, the newly approved statutory and regulatory provisions will be added to this subpart and notice of any change will be published in the Federal Register .

(d) Final approval. Mississippi has final approval for the following elements of its UST Program submitted to EPA and approved effective June 11, 1990, and the program revisions approved by EPA effective on March 18, 2024:

Code Pt. 5, Ch. 2, 280.42(b)(5) is approved as part of the UST Program only to the extent that Mississippi will not allow alternate release detection methods for hazardous substance UST systems installed on or after October 13, 2015. Sections 40 CFR 281.33(e) and 280.42(e) of the Federal regulations only allow alternate release detection methods for hazardous substance UST systems installed prior to October 13, 2015. Mississippi's section 280.42(b)(5) does not contain an analogous limitation on the use of alternative release detection methods. In practice, MDEQ does not allow alternative release detection methods for hazardous substance tanks installed after October 1, 2008. In a subsequent rulemaking, MDEQ will revise 11 Miss. Admin. Code Pt. 5, Ch. 2, R. 2.4, section 280.42(b)(5) to clarify this point.

Lamps, batteries, and fines: Fixing the 5 biggest universal waste mistakes

Lamps, batteries, and fines: Fixing the 5 biggest universal waste mistakes

Let’s be honest, managing compliance is tough. But when it comes to Universal Waste (UW), items like fluorescent bulbs, used batteries, aerosol cans, and old thermostats can expose employers to fines without them even realizing it. Why? Because Universal Waste is the ultimate regulatory paradox. These items are still classified as hazardous waste, but the EPA created a streamlined rule set (40 CFR Part 273) to make recycling easier. The problem is that many employers assume "streamlined" means "ignorable." Fixing these problems is incredibly straightforward. By tackling the most common UW mistakes, you don’t just avoid penalties; you build a predictable, efficient, and cost-effective waste program.

Top 5 universal waste violations and how to avoid them

  1. The container crime: Leaving it open - Leaving a Universal Waste container open is a common and costly mistake. When boxes or drums holding items like lamps and batteries are left unsealed or without a proper lid, the risk of contamination skyrockets. If a fluorescent tube breaks, mercury vapor escapes; if a battery leaks, corrosive material spills. An open container is considered a failure to prevent a release, which is a core hazardous waste violation. The fix is simple: close the container immediately. Train designated handlers to ensure containers remain sealed except when adding or removing waste, and use containers specifically designed for UW, such as fiber drums for lamps with secure, sealable lids. If it’s open, it’s a violation waiting to happen.
  2. The ticking clock: Missing the accumulation date - Missing the accumulation date is a violation that can cost you. Every Universal Waste container must clearly show the date when the first item was placed inside, and both Small and Large Quantity Handlers have only one year (365 days) to store UW before it must be shipped off-site. Without a visible start date, inspectors will assume you have exceeded that limit. The solution is simple: mark it and track it. Use a permanent marker to write the “Start Date” directly on the container, and do not wait until day 364 to act. A digital spreadsheet or calendar reminder can help you stay ahead, and scheduling vendor pickups between the 9- and 11-month mark creates a critical 30-day buffer against delays or conflicts.
  3. The DIY treatment disaster - Attempting to treat Universal Waste on-site is a recipe for violations. Crushing bulbs, mixing incompatible waste streams, or dismantling items to save space may seem efficient, but it is strictly prohibited under UW rules. These regulations are designed to simplify storage and not treatment. Breaking a fluorescent bulb outside of a permitted device not only risks mercury exposure but also constitutes hazardous waste mismanagement. The fix is simple is to train personnel that their role is to store and package waste correctly, not to alter or treat it. Keep fragile items in secure areas where they will not be crushed by forklifts or stacked boxes. Managing UW means preventing breakage, not creating it.
  4. The identity crisis: Improper labeling - Improper labeling is a common Universal Waste mistake that can lead to serious compliance issues. Containers marked vaguely such as “Recycling” or simply “Hazardous Waste” fail to meet regulatory requirements and create confusion for inspectors and emergency responders who need instant clarity. The term “Hazardous Waste” applies only to RCRA hazardous waste, not UW, and mixing these labels signals that your team has not properly identified the waste stream. Be specific and clear. Every UW container must include the words “Universal Waste” followed by the exact type of material, such as:
    • “Universal Waste – Spent Lamps”
    • “Universal Waste – Used Batteries”
    • “Universal Waste – Mercury-Containing Equipment”
  5. The knowledge gap: Training deficiencies - Training deficiencies are one of the most overlooked Universal Waste compliance gaps. Employees responsible for handling or managing UW must receive documented, recurring training on identification, accumulation limits, and handling protocols. Even the best-written program will fail if the staff placing items into containers do not understand the rules — especially dating and labeling requirements. Without proper training, an audit failure is almost guaranteed. The fix is straightforward — provide documented, annual training. Make sure every relevant staff member understands your facility’s specific UW streams key compliance practices. Maintain clear records of who was trained, when, and on what topics This paper trail is your strongest defense during an inspection.

Keys to remember: Universal waste compliance hinges on keeping containers closed, labeled, dated, and ensuring employees managing these materials are trained and documenting their actions. When your program is consistent, simple, and intentional, you eliminate preventable violations and turn UW management into a predictable, low-risk process.

The rapid growth of data centers creates new challenges for other regulated facilities. Expansion driven by artificial intelligence (AI) and cloud computing increases their impact on environmental compliance. Key areas include air permitting, attainment status, and regional power supply.

Data centers and air permitting

Data centers depend on backup power to stay online during outages. Most use natural gas or diesel generators. These units release pollutants such as nitrogen oxides (NOₓ) and particulate matter. When many generators operate together, their potential emissions can push regions close to or beyond National Ambient Air Quality Standards (NAAQS). This shift can threaten local attainment status and make it harder for nearby facilities to get new permits.

What EPA is doing

On December 11, 2025, the Environmental Protection Agency's (EPA’s) Office of Air and Radiation launched a “Clean Air Act Resource for Data Centers” webpage. It provides regulatory guidance, permitting tools, and technical letters. The goal is to make air permitting for data centers faster and more transparent while protecting air quality.

Why this matters for other regulated facilities

  • Attainment status at risk

Large data centers add cumulative emissions from multiple generators. Even permitted emissions from nearby plants can combine and push an area into nonattainment. That change triggers stricter air permitting rules for everyone.

  • Power demand competition

Data centers use large amounts of electricity. They often need on-site generators or new grid connections. This can strain local power supplies. In some cases, grid operators give data centers priority during peak demand, leaving other facilities with less reliable power.

  • Stricter air quality modeling requirements

Some states now require detailed modeling for backup generators. For example, Illinois reviewed 34 generators for one data center before granting a permit. If modeling shows high emissions, regulators may limit operating hours or require extra controls.

Broader regulatory shifts

EPA recently updated its interpretation of New Source Review (NSR) rules. In September 2025, the agency said construction can start before full air permits are issued, as long as emission-related work waits for approval. This speeds up projects but makes it harder for neighboring facilities to predict cumulative emissions early.

What non-data center facilities should do

  • Stay informed

Watch for new data center projects in your area. Their emissions could affect your permits.

  • Engage early

Join public comment periods for data center permits. Push for full modeling of combined impacts.

  • Plan for power

Work with grid operators. Understand how demand-response programs and EPA’s “50-hour rule” for emergency generators affect your reliability.

  • Choose sites wisely

Consider locating new projects in areas with robust infrastructure and cleaner attainment status. Data centers might compete for the same grid upgrades or site approvals.

Key to remember: Data centers are more than tech hubs. They influence air permitting and power allocation. Their growth can affect your ability to expand, or even operate, under current compliance rules.

Acid Rain Program compliance: SO2 vs. NOx
2025-12-11T06:00:00Z

Acid Rain Program compliance: SO2 vs. NOx

Did you know that the federal government regulates the power sector’s impact on rain? The Acid Rain Program limits the amount of sulfur dioxide (SO2) and nitrogen oxides (NOx) — the main causes of acid rain — that fossil fuel-fired electric generating units (EGUs) may emit. However, the SO2 and NOx reduction programs operate differently, and the ways that facilities can meet the SO2 and NOx limits are distinct.

It's essential to know the compliance options because facilities that don’t meet the SO2 and NOx standards must pay penalties for their excess emissions. And in November 2025, the Environmental Protection Agency (EPA) set higher penalties for the next two compliance years.

So, what are the differences?

Who’s affected?

The first thing to confirm is whether your facility is subject to the Acid Rain Program (40 CFR 72.6). The program regulates fossil fuel-fired power plants. It applies to:

  • EGUs that serve generators with an output capacity of more than 25 megawatts, and
  • All new EGUs.

Note that the NOx program applies to a specific subset of coal-fired boilers.

SO2 reduction program

EPA operates the SO2 reduction program through an allowance trading system (Part 73). The agency sets a cap on the total SO2 emissions for the year and then allocates SO2 allowances to regulated units. One allowance represents 1 ton of SO2 emissions.

For each compliance year, a facility must show that it has enough allowances to cover its emissions of SO2. It’s similar to EPA’s hydrofluorocarbon allowance program.

There are multiple compliance options. Facilities may:

  • Sell extra allowances if they have more allowances than needed,
  • Save extra allowances if they have more allowances than needed (and use them in the future), or
  • Buy extra allowances if they can’t keep emissions below their allocated level.

Facilities can purchase allowances from or sell allowances to individuals, companies, groups, or brokers. Additionally, facilities may bid on allowances at EPA’s annual Acid Rain Program SO2 Allowance Auction.

NOx reduction program

EPA sets annual emission limits for the NOx reduction program (Part 76), which applies to these types of boilers:

  • Dry bottom wall-fired boilers,
  • Tangentially fired boilers,
  • Cell burner boilers,
  • Cyclone boilers,
  • Vertically fired boilers, and
  • Wet bottom boilers.

Like the SO2 program, the NOx program offers multiple compliance options. Facilities can:

  • Meet the standard annual emission limitations,
  • Average the emissions rates of two or more boilers, or
  • Apply for an alternative emission limit (AEL) if they can’t meet the standard emission limit.

Additional requirements apply to facilities that use options other than complying with the limits:

  • Facilities that want to average emissions rates must submit an averaging plan that’s approved by the permitting authorities (76.11).
  • Facilities that apply for an AEL are required to use the NOx emission control technology used as the basis for the emission limit and must demonstrate that the unit can’t comply using the technology (76.10).

It pays (or, at least, costs less) to comply!

Excess emissions penalties can add up quickly. That’s why it’s vital to ensure your facility understands how to comply with the SO2 and NOx reduction programs properly.

The adjustment rates that EPA set for compliance years 2025 and 2026 (2.5265 and 2.6001, respectively) are used to calculate the total penalties a facility must pay if it exceeds SO2 or NOx limits during these compliance years.

Here are the formulas:

  • Penalty for excess SO2 emissions = $2,000/ton x annual adjustment factor x tons of excess SO2 emissions
  • Penalty for excess NOx emissions = $2,000/ton x annual adjustment factor x tons of excess NOx emissions

Let’s run through a couple of examples of what noncompliance could cost.

FactorsPenalty Per TonTotal Penalties
  • Tons of excess SO2 emissions: 10
  • Compliance year: 2025
  • Annual adjustment factor: 2.5265
$2,000 x 2.5265 = $5,053$5,053 x 10 = $50,530
  • Tons of excess NOx emissions: 5
  • Compliance year: 2026
  • Annual adjustment factor: 2.6001
$2,000 x 2.6001 = $5,200.20$5,200.20 x 5 = $26,001

As shown in the example above, excess emissions can cost facilities a lot in penalties. Just 1 ton of excess emissions will result in more than $5,000! Knowing your compliance options for the Acid Rain Program’s SO2 and NOx reduction programs can help your facility avoid steep fines.

Key to remember: The Acid Rain Program limits SO2 and NOx emissions from fossil fuel-fired power plants, but the compliance options for each type of emission differ. Understanding the distinct options can help facilities avoid penalties for excess emissions.

EPA’s 2026 regulatory shift: How environmental managers can stay ahead
2025-12-05T06:00:00Z

EPA’s 2026 regulatory shift: How environmental managers can stay ahead

The clock is ticking for environmental teams. By 2026, several new EPA regulations will reshape compliance obligations for U.S. companies. Organizations that act now will avoid costly penalties and operational disruptions.

What’s changing and why it matters

Although EPA has been deregulating or loosening some requirements, there are still some standards being tightened across multiple fronts in the coming year:

  • Renewable fuel standards (RFS): The EPA proposed higher volume requirements for 2026, including 24.02 billion renewable identification numbers (RINs), up nearly 8% from 2025. This increase pushes stricter expectations on fuel producers and organizations purchasing renewable fuels.
  • Stormwater multi-sector general permit (MSGP): A new MSGP set to take effect by February 2026 will require quarterly PFAS indicator monitoring, expanded benchmark sampling, and resiliency measures in stormwater control designs.
  • PFAS Reporting under the Toxic Substances Control Act (TSCA): TSCA Section 8(a)(7) mandates PFAS manufacturing and import data collection beginning in April 2026, through October 2026, with extended deadlines for certain small manufacturers.

Failure to prepare could lead to fines, reputational damage, supply chain disruptions, and permit delays. Companies that weave compliance planning into their 2026 strategy will be positioned not just to meet legal deadlines but to sustain operations smoothly.

Key areas of impact

  • Renewable fuel standards (RFS) and air emissions The proposed increase in 2026 Renewable Identification Numbers (RIN) volumes, from 24.02 billion to 24.46 billion for 2027, signals tightening air and fuels policy that affects fuel use and emissions accounting.
  • Stormwater management The upcoming 2026 MSGP requires expanded quarterly PFAS monitoring, new benchmark triggers, corrective action plans, and integration of climate resilience in design standards.
  • PFAS disclosure (TSCA Section 8(a)(7)) Manufacturers and importers of PFAS must submit electronic reporting of usage, volumes, disposal, and exposure data between April and October 2026, with extensions available for smaller operations.

Steps to take now

  • Audit compliance programs: Cross-check operations against RIN inventory, stormwater permits, and TSCA reporting duties.
  • Upgrade monitoring and recordkeeping: Implement robust electronic systems to track PFAS, stormwater quality, fuel volumes, and emissions.
  • Staff training: Educate teams on PFAS obligations, new stormwater protocols, and RFS structures.
  • Engage regulators early: Comment on proposed rules, consult during permit drafting, and flag issues during the notice-and-comment period.

Looking ahead

The EPA’s 2026 updates reflect a trend toward increased transparency and environmental accountability. Companies that treat compliance as strategic will not only avoid enforcement but also gain resilience and stakeholder trust.

Key to remember: Start planning now. Early action on EPA rule changes will save time, money, and headaches when enforcement begins.

EPA confirms oil, gas emissions compliance extensions
2025-12-05T06:00:00Z

EPA confirms oil, gas emissions compliance extensions

The Environmental Protection Agency (EPA) issued a rule on December 3, 2025, that finalizes compliance deadline extensions for certain emissions standards applicable to crude oil and natural gas facilities. The final rule also further delays compliance timelines for two requirements.

EPA’s delays affect:

  • The New Source Performance Standards for crude oil and natural gas facilities (40 CFR 60 Subpart OOOOb), and
  • The emissions guidelines (EGs) for crude oil and natural gas facilities (60 Subpart OOOOc).

EPA’s December 2025 final rule is a direct response to the interim final rule (IFR) it issued in July 2025.

The July 2025 IFR extended the compliance deadline for net heating value (NHV) monitoring of flares and enclosed combustion devices (ECDs) to November 28, 2025. The IFR moved the rest of the compliance deadlines to January 22, 2027, for:

  • ECD performance tests;
  • Cover and closed vent system requirements for no identifiable emissions (NIEs), including:
    • Design and operation standards,
    • Test methods and procedures, and
    • Inspections.
  • Equipment leak repair requirements;
  • Phase two of zero-emission standards for process controllers;
  • Storage vessel requirements, including:
    • Using potential emissions limits that qualify as legally and practicably enforceable,
    • Triggering throughput-based modifications, and
    • Using a 30-day period of production to calculate potential emissions.
  • Flare and ECD pilot flame rules, including:
    • Ensuring the devices operate with a continuous pilot flame, and
    • Installing and operating a system to send an alarm to the nearest control room when a pilot flame is unlit.
  • Implementation of the Super Emitter Program, and
  • Submission of state plans for implementing the updated EGs.

What’s the same?

EPA’s December 2025 final rule maintains the same compliance deadlines for all requirements delayed to January 22, 2027.

What’s different?

The agency’s December 2025 final rule sets a new compliance date of June 1, 2026, for the NHV monitoring requirements. This includes an alternative performance test (sampling demonstration) option for flares and ECDs.

Additionally, the rule moves the compliance date for annual reporting, establishing that no annual report is due before November 30, 2026. It gives owners and operators until November 30, 2026, to submit any reports that were originally due before this date. Note that the final rule specifies that annual reports due after November 30, 2026, must be submitted within 90 days of the end of each annual compliance period.

Key to remember: EPA’s final rule confirms deadline extensions for certain emissions standards that apply to crude oil and natural gas facilities. It also further delays a couple of the requirements.

Annual HFC report: First submissions due March 2026
2025-11-25T06:00:00Z

Annual HFC report: First submissions due March 2026

What do the manufacturers of hairspray cans, foam wall insulation, and ice cream machines have in common? If their products contain hydrofluorocarbons (HFCs), they have to report annually on the HFCs they use, and the first report due date is quickly approaching! Through the Technology Transitions Program, the Environmental Protection Agency (EPA) regulates HFCs used for new products and equipment in three sectors: aerosols, foams, and refrigeration, air conditioning, and heat pumps (RACHP). Among other compliance requirements of the 2023 Technology Transitions Rule, manufacturers and importers of HFC-containing products and equipment must submit annual reports.

Note: EPA’s October 2025 proposed rule to amend the 2023 Technology Transitions Rule doesn’t impact annual reporting requirements.

Use this overview to help you determine whether your business needs to report and, if so, what’s required.

Who reports?

Annual reporting applies to manufacturers and importers of products and equipment that use HFCs. An organization has to submit an annual report if:

  • It manufactures or imports a product or component within a regulated sector or subsector (see 40 CFR 84.54), and
  • The product or component uses or will use a regulated HFC or HFC blend.

Reporting requirements apply to manufacturers and importers in all sectors and subsectors, and they start with data from calendar year 2025. The first annual report is due to EPA by March 31, 2026.

Note that the annual reporting requirements don’t apply to entities that only:

  • Sell or distribute equipment, or
  • Install or operate new RACHP systems.

What’s reported?

In each annual report, covered manufacturers and importers must provide:

  • The entity’s name and address;
  • The entity’s contact person, the contact's email address, and the contact's phone number;
  • The calendar year covered by the report and the submission date;
  • All applicable North American Industry Classification System (NAICS) codes; and
  • A statement certifying that the data is accurate and that the products use HFCs or HFC blends in compliance with the use restrictions and labeling requirements.

Entities in all three sectors also have to report the total mass in metric tons of each HFC or HFC blend contained in all products and components manufactured, imported, and exported annually.

Further, sector-specific standards apply.

SectorRequires additional information for:See 40 CFR:
Aerosol
  • Sets of products with the same HFC combination and quantity
84.60(a)(5)
Foam
  • Sets of products (excluding foam-blowing containers) with the same HFC density and identity
  • Containers or foam-blowing products with foam-blowing agents
84.60(a)(4)
RACHP
  • Sets of products or components with the same charge size and HFC combination
  • Products or components with HFC-containing closed-cell foam
84.60(a)(3)

How’s the report submitted?

According to the latest information shared by EPA in the “Technology Transitions Program: What You Need to Know for January 1, 2025” webinar presentation, the agency is still designing the electronic platform for submitting annual reports. EPA plans to provide reporting instructions and forms before the upcoming deadline.

About the 2023 Technology Transitions Rule

HFCs are greenhouse gases that were developed to replace ozone-depleting substances for use in various products and equipment (primarily refrigeration and air-conditioning systems). The American Innovation and Manufacturing Act of 2020 gives EPA the authority to address HFCs by:

  • Phasing down production and consumption through the HFC Allowance Allocation Program,
  • Implementing restrictions on HFC use in specific sectors, and
  • Developing regulations to maximize the reclamation and minimize the release of HFCs from equipment.

The 2023 Technology Transition Rule established the Technology Transitions Program to restrict HFC uses in sectors and subsectors where lower global warming potential (GWP) technologies are or will soon be available. The regulations apply to manufacturers (including importers), exporters, sellers, distributors, and installers of systems or products in covered sectors that use HFCs.

What about the proposed changes to the 2023 Technology Transitions Rule?

On October 3, 2025, EPA proposed a rule to amend the existing 2023 Technology Transition Rule. However, the proposed changes don’t affect the annual reporting requirements for manufacturers and importers. All covered manufacturers and importers must submit the annual report by March 31, 2026.

The proposed rule impacts specific subsectors, including refrigerated transport, industrial process refrigeration, chillers, retail food (for supermarkets and remote condensing units), cold storage warehouses, and stationary residential and light commercial air conditioning and heat pumps. EPA proposes to:

  • Exempt certain intermodal containers transporting cargo at very cold temperatures;
  • Extend compliance dates for industrial process refrigeration used in semiconductor manufacturing;
  • Raise global warming potential thresholds for remote condensing units, supermarket systems, and cold storage warehouses;
  • Extend compliance dates for refrigerated centrifuges and laboratory shakers; and
  • Allow existing residential and light commercial air-conditioning and heat pump equipment (i.e., manufactured or imported before January 1, 2025) to continue to be installed.

Key to remember: The first annual reports required by the Technology Transitions Program for manufacturers and importers of HFC-containing products and equipment are due by March 31, 2026.

EPA’s SDS/Tier II reporting now in lockstep with OSHA HazCom
2025-11-25T06:00:00Z

EPA’s SDS/Tier II reporting now in lockstep with OSHA HazCom

EPA issued a direct final rule to update its safety data sheet (SDS) reporting and Tier II inventory reporting requirements. The changes align EPA 40 CFR 370 with OSHA’s Hazard Communication (HazCom) standard at 29 CFR 1910.1200.

News update: EPA extended the public comment period for this direct final rule that made technical amendments to 40 CFR 370 to conform to the 2024 OSHA HazCom standard. An EPA memo lodged in docket EPA-HQ-OLEM-2025-0299 at Regulations.gov, explains, “This document will be open for public comment until December 24, 2025.” Also, note that the docket offers 23 supporting and related materials, including a draft updated Tier II form, draft updated Tier II instructions, and a redline strikeout version of the rule changes.

The biggest change is that facilities will be able to copy the hazard categories directly from section 2 of the SDSs to their Tier II report forms. This eliminates the guesswork. However, facilities may face added strain with their first Tier II submission under the rule. Instead of relying on the grouped hazard categories selected in the previous year’s forms, it looks like facilities will need to spend extra time retrieving specific categories from their SDSs.

Who’s impacted by the rule?

EPA 40 CFR 370 applies to a facility owner or operator if:

  • The OSHA HazCom standard requires the facility to prepare or have available an SDS or material safety data sheet (MSDS) for a hazardous chemical;
  • The hazardous chemical is not exempted at 370.13 or 1910.1200(b)(6); and
  • The hazardous chemical is present at or above certain threshold levels.

If the applicability criteria are met, the facility owner/operator must submit to the state emergency response commission (SERC), local emergency planning committee (LEPC), and local fire departments:

  • An SDS or MSDS for each covered hazardous chemical or a list of all covered hazardous chemicals; and
  • A Tier II hazardous chemical inventory form by March 1 annually for all covered hazardous chemicals.

A state may make its own laws and regulations in addition to or more stringent than federal Part 370.

What’s changing in Part 370?

Last year, OSHA amended its HazCom standard to conform to the seventh edition of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Changes to the chemical hazard classifications and categories were part of the amendments to 1910.1200. This is important because EPA Part 370 relies on the OSHA HazCom standard for the definition of “hazardous chemical” and the hazard categories that must be reported.

In the latest rule published November 17, 2025, EPA takes several actions to harmonize its regulations with OSHA’s. The preamble offers a complete list of amendments to Part 370. Here’s a summary:

Change:Details:Sections affected:
Adopts all 112 OSHA hazard categories
  • The hazard categories are amended to include the full list of OSHA hazard classes with their categories for health and physical hazards. (Previously, EPA used an abbreviated list of hazard classes. The change impacts both SDS reporting and Tier II reporting.)
370.3, 370.30, 370.41, and 370.42
Updates terminology
  • The definitions are moved from 370.66 to 370.3.
  • The definition for the term “hazard category” now means the classification of a chemical’s hazard(s) into classes with their categories as are reported in section 2 of SDSs in accordance with 1910.1200.
  • The terms “health hazards” and “physical hazards” are updated to align with OSHA. However, “simple asphyxiants” will remain a health hazard, “combustible dust” will remain a physical hazard, and “hazard not otherwise classified” will remain both a physical hazard and a health hazard.
  • The definition of “material safety data sheet (MSDS)” is removed.
  • Minor changes to other terms are made for plain language, clarity, and consistency purposes.
370.3 and 370.66
Removes the term MSDS
  • The terms MSDS and material safety data sheet are removed to conform to the OSHA HazCom standard.
370.3, 370.10, 370.12, 370.13, 370.14, 370.20, 370.30, 370.31, 370.32, 370.33, 370.60, 370.62, 370.63, and 370.64
Makes minor plain language, clarifying, and consistency corrections
  • Historic dates and clarifications for electronic reporting are removed.

370.1, 370.2, 370.3, 370.10, 370.14, 370.30, 370.32, 370.33, 370.40, 370.41, 370.42, 370.43, 370.44, 370.45, 370.60, 370.61, 370.62, 370.64, 370.65, and 370.66

When will the changes take effect?

The direct final rule is effective January 16, 2026, unless EPA receives an adverse comment during its 30-day comment period. [However, see the "news update," earlier in this article.] If that happens, the agency will publish a timely withdrawal. Then, it will move along with the proposed rule (also published in the November 17, 2025, Federal Register) and address public comments in a subsequent final rule.

Assuming no adverse comment is received on the original direct final rule, EPA gives covered facilities time to prepare. The rule offers a compliance date of December 1, 2026, for both SDS reporting and Tier II reporting. Note that for Tier II reporting, the updates kick in for the 2026 inventory reporting year, which impacts forms due by March 1, 2027, and thereafter. (Forms due on or before March 1, 2026, are unchanged.)

Key to remember

EPA took action to harmonize Part 370 with the changes OSHA made to 1910.1200 last year. The latest amendments to Part 370 have a compliance date of December 1, 2026. For Tier II reporting, the updates start with forms due on or before March 1, 2027.
