VOC RACT Compliance: Lessons from the NH Hutchinson Sealing Systems SIP

The lesson here isn't just about one facility in Newfields, New Hampshire. It's about what happens when a state's air quality enforcement mechanism catches up with a single-source emitter — and what every manufacturing facility with VOC emissions should do before that spotlight lands on them.

On March 23, 2026, the U.S. Environmental Protection Agency published a final rule in the Federal Register approving a State Implementation Plan (SIP) revision submitted by the State of New Hampshire (Federal Register Doc. 2026-05567). The revision centers on a revised Reasonably Available Control Technology (RACT) order for Hutchinson Sealing Systems, a manufacturing facility located in Newfields, New Hampshire.

This action was taken under the authority of the Clean Air Act (CAA), specifically under provisions governing State Implementation Plans and RACT requirements for volatile organic compound (VOC) emissions. For environmental managers, EHS directors, and operations leaders at any manufacturing facility, this regulatory action is a textbook case study in how RACT obligations evolve — and how to stay ahead of them.

What Is a VOC RACT Order and Why Does It Matter?

Reasonably Available Control Technology (RACT) is defined by the 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. RACT requirements under the Clean Air Act apply primarily to major stationary sources of VOC emissions located in ozone nonattainment areas or areas subject to transport rules under the CAA Section 182.

VOCs are precursors to ground-level ozone (smog), a criteria pollutant regulated under the National Ambient Air Quality Standards (NAAQS). The EPA has set the current ozone NAAQS at 0.070 parts per million (ppm) averaged over eight hours, a standard that continues to drive RACT enforcement actions across the northeastern United States.

A single-source RACT order is a site-specific, enforceable permit condition or order issued to a named facility when that facility's VOC emissions are significant enough to warrant individual regulatory attention — rather than being addressed through a generalized, industry-wide rule. These orders are incorporated into a state's SIP and, once EPA-approved, carry the full weight of federal law.

A facility subject to a single-source RACT order is operating under a federally enforceable emissions limitation that is directly incorporated into the state's Clean Air Act implementation framework — violations can trigger both state and federal enforcement.

The Hutchinson Sealing Systems Action: What Changed

Hutchinson Sealing Systems, located in Newfields, New Hampshire, is a manufacturing facility that produces sealing and anti-vibration components, operations that typically involve VOC-emitting adhesives, coatings, and solvents. The facility falls under New Hampshire's air quality regulatory jurisdiction, administered by the New Hampshire Department of Environmental Services (NH DES).

The SIP revision approved on March 23, 2026 is specifically a revised RACT order — meaning this is not the first time Hutchinson Sealing Systems has been subject to RACT obligations. The revision represents a regulatory update, likely reflecting one or more of the following:

• Changes in production processes or emission sources at the facility since the original RACT order was issued
• Updated EPA RACT guidance or more stringent control technology determinations at the federal level
• Revised VOC emission inventories submitted by the facility during a periodic SIP review cycle
• Negotiated compliance pathway adjustments between the facility and NH DES

This is a critical nuance: RACT orders are not static. They can and do get revised when underlying conditions change, and each revision must be approved by EPA as a SIP amendment before it becomes federally enforceable.

Key Regulatory Details at a Glance

Why Single-Source RACT Orders Are Increasing

The Northeast and Mid-Atlantic states have seen a steady uptick in single-source RACT determinations over the past decade, driven by several converging regulatory forces:

1. Ozone transport obligations: Under the EPA's Good Neighbor Provision (CAA Section 110(a)(2)(D)), upwind states like New Hampshire must ensure their emissions don't significantly contribute to ozone nonattainment in downwind states. This creates pressure on state agencies to tighten VOC controls on individual large emitters.

2. Periodic SIP revision cycles: EPA requires states to periodically reassess and update their SIPs. When a state submits a SIP revision, EPA scrutinizes existing single-source orders and may require updates to reflect current RACT standards.

3. Increased EPA scrutiny of manufacturing sectors: Sectors with diffuse VOC sources — rubber manufacturing, adhesive application, surface coating — are receiving heightened attention as EPA works to bring more areas into ozone NAAQS attainment.

According to EPA data, VOCs from industrial sources account for approximately 20% of total anthropogenic VOC emissions in the United States, making manufacturing facilities a consistent enforcement priority.

In ozone nonattainment areas, a single manufacturing facility emitting above the major source threshold of 50 tons per year of VOCs can trigger RACT obligations that require facility-specific engineering analysis and legally binding control commitments.

What This Means for ISO 14001-Certified Facilities

For facilities operating under an ISO 14001 Environmental Management System (EMS), a regulatory action like this one carries direct implications for your compliance obligations framework. ISO 14001:2015 specifically addresses legal and other requirements under clause 6.1.3 — and a revised, federally approved RACT order is precisely the type of binding obligation that must be captured in your compliance register.

Here's where I see facilities make mistakes in my consulting practice at Certify Consulting:

Mistake #1: Treating RACT Orders as Static Documents

Facilities often capture an original RACT order in their compliance register and never revisit it. When the state revises the order and EPA approves a SIP amendment, the compliance register becomes outdated — sometimes by years. Under ISO 14001:2015 clause 9.1.2, you are required to evaluate compliance with all applicable legal requirements on a defined schedule. An outdated RACT order in your register is a nonconformance waiting to happen.

Action item: Build a regulatory change monitoring protocol into your EMS that tracks Federal Register notices for your industry sector and geographic region. Set up alerts for your state's EPA region (New Hampshire is in EPA Region 1 — New England).

Mistake #2: Siloing Air Permitting from the EMS

Air quality permits and RACT orders are often managed exclusively by the air compliance team, with limited integration into the broader ISO 14001 EMS. This creates blind spots. Your EMS should treat air permit conditions — including RACT emission limits — as significant environmental aspects with associated operational controls under clause 8.1.

Action item: Map each RACT emission limit to a specific operational control procedure. For VOC sources, this typically means documented procedures for solvent handling, adhesive application equipment maintenance, and emission capture system inspection logs.

Mistake #3: Failing to Plan for RACT Revisions

If your facility is subject to a single-source RACT order, you should be conducting an internal RACT self-assessment every two to three years — not waiting for the state to initiate a revision. Proactive facilities that approach NH DES (or their respective state agency) with updated emission inventories and control technology assessments are far more likely to negotiate favorable revised RACT terms than those who are reactive.

Practical Compliance Guidance: A Step-by-Step Approach

If your facility operates in New Hampshire or any other northeastern state and is subject to RACT obligations, here is the structured approach I recommend to clients at Certify Consulting:

Step 1: Confirm Your Current RACT Status

• Review your Title V or state operating permit for RACT-based emission limits
• Verify whether you are operating under a facility-specific RACT order or a generic RACT rule (industry-wide)
• Check the NH DES Air Resources Division database or your EPA regional docket for any pending SIP revisions affecting your facility

Step 2: Update Your Compliance Register

• Capture the specific emission limits from the RACT order (expressed in lbs/hr, tons/year, or process-rate-based units)
• Note the effective date of the current order and any revised order
• Document the monitoring, recordkeeping, and reporting requirements associated with each limit

Step 3: Conduct a Gaps Analysis Against Current Operations

• Compare actual emission rates (from your most recent emission inventory or stack test results) against RACT permit limits
• Identify any operational changes since the last RACT determination that may have altered your VOC emission profile
• Evaluate whether current control equipment (thermal oxidizers, carbon adsorbers, low-VOC substitutions) remains adequate

Step 4: Align EMS Operational Controls with RACT Requirements

• Update clause 8.1 operational control procedures to reflect current RACT limits
• Ensure your environmental monitoring and measurement program (clause 9.1.1) captures the parameters required by the RACT order
• Verify that training records document operator awareness of VOC emission limits and control procedures

Step 5: Establish a Regulatory Watch Protocol

• Subscribe to Federal Register email alerts for EPA Region 1 and your relevant SIC/NAICS codes
• Monitor NH DES rulemaking notices on a quarterly basis
• Assign a specific individual in your EMS with responsibility for regulatory change identification under ISO 14001:2015 clause 6.1.3

The Broader Compliance Picture: VOC Emissions and Air Quality Trends

The Hutchinson Sealing Systems action is part of a broader national pattern. The EPA's ongoing efforts to address ozone nonattainment — particularly in the Northeast, where interstate transport complicates attainment — mean that single-source RACT actions will continue to increase in frequency through 2026 and beyond.

Several trend lines reinforce this:

• Approximately 35% of the U.S. population lives in counties that do not meet the 2015 ozone NAAQS, according to EPA's most recent air quality data, maintaining regulatory pressure on VOC sources.
• The EPA's 2023 Good Neighbor Plan, though subject to ongoing litigation, reflected the agency's intent to further tighten interstate ozone transport controls — a posture that drives state RACT stringency upward.
• New Hampshire specifically has classified portions of its territory as being in the Ozone Transport Region (OTR) under CAA Section 184, which subjects even smaller VOC sources (above 50 tons per year, rather than the standard 100-ton threshold) to RACT requirements.

Summary: Key Takeaways for Environmental Managers

The EPA's approval of New Hampshire's revised RACT order for Hutchinson Sealing Systems is a reminder that air quality compliance is not a one-time event — it is a continuous obligation that evolves with your operations, with state regulatory priorities, and with EPA's interpretation of federal standards.

For any manufacturing facility with significant VOC emissions, particularly in northeastern states participating in the Ozone Transport Region, the message is clear:

1. Know your RACT status — are you under a facility-specific order or a generic rule?
2. Monitor for SIP revisions — RACT orders can and do get updated, and federal approval makes them immediately enforceable
3. Integrate air compliance into your ISO 14001 EMS — RACT limits are legal obligations under clause 6.1.3 and must be actively managed
4. Be proactive, not reactive — facilities that engage with regulators ahead of revision cycles have more control over their compliance outcomes

The Hutchinson Sealing Systems action is a compliance signal worth heeding. Don't wait for your facility's name to appear in the Federal Register.
