Compliance Takeaway: When the EPA approves a revised RACT order within a State Implementation Plan, it isn't just a regulatory formality for the named facility — it's a signal to every similarly situated manufacturer about the emissions control standards regulators now consider "reasonably available." If your facility handles volatile organic compounds (VOCs), this action is worth understanding in detail.
What Just Happened: EPA Approves New Hampshire's Revised VOC RACT Order
On March 23, 2026, the U.S. Environmental Protection Agency published a final rule in the Federal Register (Docket No. 2026-05567) approving a State Implementation Plan (SIP) revision submitted by the State of New Hampshire. At the center of this action is a revised Reasonably Available Control Technology (RACT) order for Hutchinson Sealing Systems, a manufacturing facility located in Newfields, New Hampshire.
This action was taken in accordance with the Clean Air Act (CAA), which requires states to demonstrate that major stationary sources of VOC emissions are operating with controls that meet RACT standards — particularly in areas designated as nonattainment for ground-level ozone under the National Ambient Air Quality Standards (NAAQS).
For compliance professionals, environmental managers, and quality leaders at manufacturing facilities across the Northeast, this EPA approval carries direct and practical implications. Let me break it down.
Understanding the Regulatory Framework: What Is a VOC RACT Order?
The Clean Air Act's RACT Requirement
Under Clean Air Act Section 182, states with ozone nonattainment areas are required to submit SIP revisions demonstrating that major VOC sources — generally defined as facilities emitting 100 tons per year or more of VOCs in Moderate nonattainment areas, or 50 tons per year or more in Serious and above areas — are subject to RACT.
RACT is defined by EPA as "the lowest emission limitation that a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility." This is a facility-specific, technology-specific standard — not a one-size-fits-all rule.
When a state cannot cover a particular source under a categorical RACT rule (known as a "control technique guideline" or CTG rule), it must issue a case-by-case RACT determination — which is exactly what New Hampshire did for Hutchinson Sealing Systems through this RACT Order.
Why Single-Source RACT Orders Matter
Single-source RACT orders are significant for three reasons:
- They set a precedent. EPA's approval of a state's RACT determination for one facility signals what the agency considers acceptable for similar processes and industries.
- They are legally enforceable. Once incorporated into the SIP, RACT orders carry the force of federal law under 40 CFR Part 52.
- They trigger compliance obligations with real deadlines. Facilities subject to approved RACT orders must operate in continuous compliance — there are no grace periods post-approval.
Hutchinson Sealing Systems: Who They Are and Why This Matters
Hutchinson Sealing Systems, located in Newfields, New Hampshire, is a manufacturer of sealing and fluid management systems — product lines that commonly involve the use of solvent-based adhesives, coatings, and surface preparation chemicals that are significant sources of VOC emissions.
New Hampshire is part of the Ozone Transport Region (OTR), a multi-state area where ground-level ozone is a persistent air quality concern. The OTR includes the entire Northeast corridor from Maine to Virginia, meaning facilities in these states face more stringent RACT requirements than facilities in other parts of the country.
The revision approved in this action updates an existing RACT order for Hutchinson Sealing Systems — indicating that the facility's operations, production processes, or emission control systems have changed in a way that warranted a fresh RACT determination. This is a normal part of the regulatory lifecycle for long-operating facilities.
The EPA Approval: What Specifically Changed
While the full technical specifics of the revised RACT order are detailed in New Hampshire's SIP submission and EPA's rulemaking record, the EPA's approval confirms the following:
- New Hampshire's revised RACT order meets the requirements of the Clean Air Act and EPA's implementing regulations at 40 CFR Part 51, Subpart F (Review of New Sources and Modifications).
- The revised order reflects updated emission limitations, operational requirements, or control technology specifications for VOC-emitting processes at the Newfields facility.
- EPA evaluated the state's technical analysis and determination that the controls required by the order represent RACT for Hutchinson Sealing Systems' specific processes and economic circumstances.
- The approved SIP revision is federally enforceable as of the effective date of the Federal Register publication — March 23, 2026.
This is a direct final rule, meaning EPA determined that the action is non-controversial and unlikely to receive adverse comments. The rule becomes effective unless EPA receives adverse public comment within the comment period specified in the Federal Register notice.
Key Dates and Deadlines
| Milestone | Date |
|---|---|
| Federal Register Publication | March 23, 2026 |
| EPA Rule Effective Date | March 23, 2026 (direct final) |
| SIP Revision Submission by NH | Prior to publication (exact date in docket) |
| Hutchinson Facility Compliance Obligation | Continuous, from effective date forward |
| Adverse Comment Deadline | Typically 30 days from publication (approx. April 22, 2026) |
Citation Hook: The EPA's approval of New Hampshire's revised RACT order for Hutchinson Sealing Systems, effective March 23, 2026, makes the facility's updated VOC emission limitations federally enforceable under 40 CFR Part 52 and the Clean Air Act.
VOC RACT vs. Other Air Emission Standards: A Comparison
Understanding how RACT fits into the broader landscape of air quality regulations helps manufacturers calibrate their compliance programs appropriately.
| Standard | Basis | Who It Applies To | Stringency Level |
|---|---|---|---|
| RACT (Reasonably Available Control Technology) | Technological & economic feasibility | Existing major sources in nonattainment areas | Moderate — baseline for existing sources |
| BACT (Best Available Control Technology) | Best performing technology | New or modified major sources (PSD areas) | High — reflects current best practice |
| LAER (Lowest Achievable Emission Rate) | Lowest achievable rate regardless of cost | New or modified major sources in serious+ nonattainment | Highest — cost is not a limiting factor |
| MACT (Maximum Achievable Control Technology) | Top 12% of performing sources | Hazardous Air Pollutant (HAP) emitters | High — set by existing best performers |
| CTG Rule | EPA guidance-based category | Sources in EPA-defined source categories | Moderate — categorical approach |
| Case-by-Case RACT Order | Facility-specific analysis | Sources not covered by CTG rules | Moderate — individually determined |
Citation Hook: RACT is the minimum federal standard for existing VOC sources in ozone nonattainment areas, but it is not static — states regularly revise RACT orders as technology evolves, production processes change, or nonattainment designations are updated.
What This Means for Other Manufacturers: 5 Practical Compliance Lessons
Whether you operate a sealing systems plant, an automotive parts facility, a coatings operation, or any other manufacturing site that uses solvents or other VOC-generating materials, this EPA action contains five actionable compliance lessons.
1. Audit Your Facility's RACT Status Proactively
Many facilities were subject to RACT determinations made years — sometimes decades — ago. Those orders may no longer reflect the current state of your operations, your production volumes, or the control technology now available in your industry. If your facility's RACT order hasn't been reviewed in more than five years, it's time for an internal audit.
Ask yourself: - Has our production volume or process changed materially? - Have we added or modified emission sources covered by the RACT order? - Has EPA or our state agency issued new guidance or CTG rules for our source category?
2. Understand the Difference Between State and Federal Enforceability
A RACT order issued by a state environmental agency is enforceable under state law. But once EPA approves it as part of a SIP revision, it becomes federally enforceable under 40 CFR Part 52. This means EPA — in addition to the state — can bring enforcement actions for violations. The stakes are materially higher after SIP incorporation.
3. Monitor the Federal Register for Your Industry and Region
The Hutchinson Sealing Systems action is one of many SIP-related actions EPA takes each year. Manufacturers in the Ozone Transport Region, in particular, should have a process for monitoring the Federal Register for actions that affect their state's SIP — because these actions directly affect what your regulators consider compliant operations.
In 2024 alone, EPA took more than 200 SIP-related actions across the country, many of which involved RACT or emission reduction requirements for industrial sources.
4. Document Your Control Technology Rationale
One of the most important things you can do before a RACT review — or a regulatory inspection — is to have documented justification for every emission control decision your facility has made. This includes: - Why you selected a particular add-on control device (or chose process modification instead) - What economic analysis, if any, supported rejecting more stringent controls - What your current emission rates are relative to your permit limits
This documentation is exactly what states like New Hampshire compile when making RACT determinations, and it's what EPA evaluates when approving or rejecting SIP submissions.
5. Engage Early During SIP Revision Processes
If your state is revising its SIP or developing a RACT order for your facility, early engagement with your state agency is far more effective than commenting after the fact. The public comment period on a finalized EPA SIP approval is your last opportunity to raise concerns — but by that point, the regulatory train has largely left the station.
New Hampshire's Air Quality Regulatory Context
New Hampshire's SIP and its associated RACT program sit within a layered regulatory context that manufacturers operating in the state should understand.
New Hampshire is part of the Northeast Ozone Transport Commission (OTC) and is subject to regional emission reduction commitments that often go beyond what the CAA requires nationally. The state's air quality regulations are administered by the New Hampshire Department of Environmental Services (NHDES), Air Resources Division, which has authority to issue permits, RACT orders, and other enforceable compliance documents.
Ground-level ozone remains an air quality challenge in parts of New Hampshire, particularly in the southeastern portion of the state — including Rockingham County, where Newfields is located. The EPA's 2015 ozone NAAQS (70 parts per billion, 8-hour average) has driven renewed RACT review activity across the OTR, including actions like the one just approved for Hutchinson Sealing Systems.
Citation Hook: Facilities located in New Hampshire's Rockingham County are subject to Ozone Transport Region RACT requirements, which are among the most stringent in the United States for VOC-emitting industrial sources under the Clean Air Act.

Frequently Asked Questions
What is a VOC RACT order and why does EPA approve it?
A VOC RACT order is a facility-specific enforceable document that sets the emission limitations and operational requirements a major source of volatile organic compounds must meet, based on the lowest emission rate achievable through reasonably available and economically feasible control technology. States issue these orders for sources not covered by categorical EPA guidance rules. EPA approves them as part of State Implementation Plan revisions under the Clean Air Act, making them federally enforceable under 40 CFR Part 52.
Does the Hutchinson Sealing Systems RACT approval affect other New Hampshire manufacturers?
Not directly — RACT orders are facility-specific. However, EPA's approval signals what the agency considers RACT for processes similar to those at Hutchinson Sealing Systems. Manufacturers using comparable solvent-based adhesives, coatings, or surface preparation processes in ozone nonattainment areas should review whether their own RACT determinations remain current and defensible.
What is the effective date of the EPA's approval of New Hampshire's revised RACT order?
The EPA published the final rule approving New Hampshire's revised RACT order for Hutchinson Sealing Systems on March 23, 2026, in the Federal Register (Docket No. 2026-05567). The rule is effective as of that date as a direct final rule, subject to any adverse public comments received within approximately 30 days of publication.
What happens if a facility violates its RACT order after EPA SIP approval?
Once a RACT order is incorporated into a federally approved SIP, violations are enforceable by both the state environmental agency and the U.S. EPA. Penalties under the Clean Air Act can reach $70,787 per day per violation (adjusted for inflation under 40 CFR Part 19), and EPA may also require corrective action, facility-wide audits, or supplemental environmental projects as part of a settlement.
How often should manufacturers review their RACT status?
Best practice — and increasingly, regulatory expectation — is to review your facility's RACT status whenever there is a material change to production processes, emission sources, or control systems, and at minimum every five years. States in the Ozone Transport Region are required to periodically reassess RACT as part of their SIP obligations, and facilities that proactively update their own analyses are far better positioned during those reviews.
Summary: Key Compliance Actions to Take Now
If you're a VOC-emitting manufacturer in New Hampshire or the broader Ozone Transport Region, here's your concise action checklist following this EPA approval:
- [ ] Review your current RACT order — confirm it reflects current operations and emission sources
- [ ] Verify permit limits are still being met under current production conditions
- [ ] Check whether your SIP-approved RACT order has been revised by your state in recent years
- [ ] Document your control technology rationale in writing, with current emission data
- [ ] Monitor the Federal Register for SIP actions in your state
- [ ] Engage a compliance consultant if any gaps are identified before your state does
Regulatory approvals like this one don't happen in isolation — they are part of a continuous cycle of state and federal oversight designed to ensure that major emission sources are meeting current standards. The facilities that stay ahead of that cycle are the ones that avoid enforcement, maintain their permits, and protect their operating licenses.
