What is the maximum civil penalty under 40 CFR Part 84 Subpart C?

As of January 8, 2025, the judicial civil penalty cap is up to $124,426 per day, per violation under 40 CFR § 19.4 Table 1. Administrative penalties max out at $59,114 per day with a per-case ceiling of approximately $472,901.

How does EPA count violations under Subpart C?

Every kilogram of a regulated substance sold, distributed, or transferred in violation of Subpart C constitutes a separate violation — even less than one kilogram counts as one full violation. Each day a violation continues runs the per-day penalty clock independently.

What specific violations trigger penalties under Subpart C?

Key violations include: failure to repair leaks within 30 days (or 120 days for industrial process refrigeration), selling refrigerant without first having it reclaimed, failing to install automatic leak detection systems by January 1, 2027, providing false information to EPA, and failing to submit chronic-leaker reports due March 1 annually.

Can refrigerant violations lead to criminal charges?

Yes. Knowing violations of Clean Air Act requirements carry up to 5 years imprisonment under 42 U.S.C. § 7413(c)(1). Smuggling HFCs can be prosecuted under 18 U.S.C. § 545, carrying up to 20 years in prison and a $250,000 fine. False statements and record tampering carry up to 2 years imprisonment.

How does EPA calculate settlement penalties?

EPA uses a gravity-and-economic-benefit framework. The gravity component reflects the seriousness of harm, duration, and whether the violation undermined the HFC phasedown allowance system. The economic benefit component estimates the financial gain from non-compliance, such as avoided retrofit costs or reclamation fees.

How do records reduce penalty exposure under Subpart C?

Subpart C requires records to be kept for a minimum of three years. A facility that cannot produce records faces a presumption of non-compliance. In EPA enforcement, demonstrated good-faith compliance efforts and complete records consistently produce lower settlement figures than equivalent violations without documentation.

What is the field citation penalty amount under Subpart C?

The field citation program for minor violations allows penalties up to $11,823 per day (the inflation-adjusted figure under 40 CFR § 19.4 Table 1 as of January 8, 2025; the un-adjusted statutory base is $5,000) — the lowest enforcement tier but still significant for small operations.

What are real-world penalty benchmarks from EPA enforcement?

Resonac America paid $416,003 for illegally importing 2,800 kg of HFC-23 (March 2024). HVAC Services paid $77,679 for importing approximately 10,920 kg of HFCs without allowances (April 2024). Open Mountain Energy paid $41,566 for an attempted import of 20,000 kg of HFC-245fa (January 2024).

EPA Penalty Amounts Under 40 CFR Part 84 Subpart C: What Facility Owners Actually Face

A single Subpart C violation can cost a facility owner up to $124,426 per day. Those numbers compound fast when violations span multiple systems or run uncorrected for weeks. This article breaks down the legal authority EPA draws on, how the agency counts violations, which acts trigger penalties, and what the settlement record shows about actual exposure — so you can size the risk accurately and take the steps most likely to reduce it.

The Legal Authority Behind Subpart C Penalties

The enforcement hook is CAA section 113 (42 U.S.C. § 7413). The AIM Act pulls it in directly via 40 CFR § 84.120, which establishes Subpart C's relationship to other laws. Sections 114, 304, and 307 of the CAA also apply, giving EPA broad authority to inspect facilities, compel information, and support citizen-suit enforcement.

That statutory foundation matters for facility owners because it means the enforcement infrastructure is not new. The same legal framework used for decades to pursue Title VI ozone-protection violations is now pointed at HFC management. EPA knows how to use it.

For a given set of facts, EPA can pursue administrative actions, civil judicial actions, or criminal referrals — and they are not mutually exclusive. Owners who assume that EPA will start with a warning letter and escalate gradually should study the EPA enforcement actions and how violations are pursued — the agency has moved directly to Consent Agreement and Final Orders without prior notice in documented cases.

Maximum Civil Penalty Amounts (2025–2026 Inflation-Adjusted Figures)

Civil penalties under the Federal Civil Penalties Inflation Adjustment Act are ordinarily updated each January. The January 8, 2025 Federal Register adjustment sets the current figures, which remain in effect through calendar year 2026 — OMB Memorandum M-26-11 (April 17, 2026) cancelled the 2026 annual adjustment due to the unavailability of October 2025 CPI-U data. Verify the figures each January — they can move.

Penalty Tier	Maximum Per Day	Per-Case Cap
Judicial civil penalty	$124,426	None
Administrative penalty	$59,114	~$472,901
Field citation (minor violations)	$11,823	Per citation

The administrative ceiling (~$472,901) applies per administrative proceeding — not per violation. Once EPA escalates to federal court, that ceiling disappears and the $124,426 per-day figure applies without an aggregate cap. Field citations ($11,823/day, inflation-adjusted) represent the lowest tier but are still meaningful for smaller operations running on thin margins.

How EPA Counts Violations — The Per-Kilogram and Per-Day Structure

The counting mechanics matter because they determine how fast exposure compounds. Under 40 CFR Part 84 Subpart C, every kilogram of a regulated substance sold, distributed, or transferred in violation constitutes a separate violation. Fractions round up — less than one kilogram still counts as one full violation.

At the same time, each calendar day the violation continues runs an independent per-day penalty clock. A facility that holds 500 kg of improperly transferred refrigerant for 30 days is looking at 500 separate violations times 30 days times the applicable daily rate — before EPA applies any downward adjustment.

For allowance violations under Subpart A — which interact with Subpart C — every kilogram produced or imported without expending required allowances is similarly counted as a discrete offense. Multi-unit facilities face stacked violations if each appliance over the 15-pound charge threshold is individually out of compliance.

Practical implication: A facility with four rooftop units each over 15 pounds, all with unrepaired leaks running 45 days past the repair deadline, is not facing one penalty — it is facing four separate ongoing violations, each accumulating daily.

Specific Violation Categories Under Subpart C Facility Owners Must Know

Not every compliance gap triggers the same enforcement response, but these categories appear most frequently in EPA actions:

Late leak repair. Failure to repair leaks within 30 days of adding refrigerant that triggers the applicable leak rate threshold under 40 CFR § 84.106. Industrial process refrigeration gets 120 days, but that extension requires documented justification.
Refrigerant transfers without reclamation. Selling, distributing, or transferring recovered refrigerant to a new owner without first having it reclaimed under 40 CFR § 84.104. Each transaction can be charged as a separate violation, making this a high-count exposure for distributors or facilities that resell recovered refrigerant.
Missing automatic leak detection systems (ALDS). Facilities with appliances containing 1,500 or more pounds of a regulated refrigerant must install and annually calibrate ALDS by January 1, 2027 under 40 CFR § 84.108. Miss the deadline or skip annual calibration and the per-day clock starts.
False or misleading information. Providing inaccurate data in any petition, report, or required communication to EPA is treated as a distinct and serious violation category — separate from any underlying compliance failure.
Missed chronic-leaker reporting. If an appliance exceeds 125% of its full charge in a prior calendar year, a chronic-leaker report is due March 1. Failure to file on time is a standalone violation, independent of the underlying leak issue. See the full recordkeeping requirements under 40 CFR 84.106 for what must accompany that report.

Criminal Penalties and Aggravated Enforcement Scenarios

Civil fines are not the worst outcome. Under the criminal provisions of the Clean Air Act, knowing violations of CAA requirements carry up to 5 years imprisonment under 42 U.S.C. § 7413(c)(1). A second conviction doubles that. False statements and record tampering carry up to 2 years under separate CAA criminal provisions.

The highest-exposure scenario involves HFC smuggling. Importing HFCs in violation of 40 CFR Part 84 can be prosecuted under 18 U.S.C. § 545 (smuggling), which carries up to 20 years in prison and a $250,000 fine per count. EPA has demonstrated willingness to pursue these referrals — documented cases include arrests and conspiracy charges tied to illegal bulk HFC imports, not just permit paperwork errors.

Criminal prosecution is reserved for knowing, deliberate violations. Most facility owners who fall out of compliance do so through negligence or administrative gaps, not intentional conduct. That distinction matters to prosecutors — but it does not eliminate civil liability, and "I did not know" is not a defense to strict-liability civil penalties.

How EPA Calculates Settlement Penalties — The Gravity-and-Economic-Benefit Framework

Statutory maximums are the ceiling, not the expected outcome. EPA calculates proposed settlement figures using the October 25, 1991 CAA Stationary Source Civil Penalty Policy and, for import violations, its Interim Penalty Policy for Illegal Imports of Bulk Regulated Substances.

The calculation has two components:

Gravity-based penalty: Reflects the seriousness of the harm — extent and duration of the violation, whether it undermined the HFC phasedown allowance system, and the degree of culpability.
Economic benefit component: Estimates what the violator gained by not complying — avoided retrofit costs, delayed equipment purchases, reclamation fees that were never paid. This amount is typically non-negotiable; EPA treats it as recapturing an unfair competitive advantage.

First-time violators with minor, correctable violations may qualify for EPA's Expedited Settlement Agreement (ESA) Pilot Program, which streamlines resolution at reduced penalty levels and without formal litigation. Cooperation, early disclosure, and complete records are the factors that most consistently push penalty outcomes toward the lower end of the range.

Real-World Penalty Benchmarks From EPA Enforcement Cases

These cases come from the EPA's public AIM Act enforcement record. All three involved unlawful imports rather than facility management violations, but they illustrate how the gravity-and-economic-benefit framework produces actual dollar figures:

Resonac America — $416,003 (March 2024)

Paid $416,003 under a Consent Agreement and Final Order for illegally importing 2,800 kg of HFC-23 without expending required allowances. The per-kilogram effective penalty: approximately $149.

HVAC Services — $77,679 (April 2024)

Paid $77,679 for importing approximately 10,920 kg of R-404A, R-410A, and R-407C without allowances. Per-kilogram effective penalty: approximately $7.12 — lower rate reflecting the lower GWP and cooperation.

Open Mountain Energy — $41,566 (January 2024)

Paid $41,566 for an attempted import of 20,000 kg of HFC-245fa. The lower per-kilogram rate reflected early settlement and the fact that the shipment was intercepted before full distribution.

Pattern: Per-unit penalties moderate significantly with cooperation and early settlement, but base exposure scales directly with the weight of refrigerant involved. Facilities with large charges and documented leaks face the same scaling dynamic on the leak repair side.

How Audit-Ready Record Retention Functions as Penalty Insurance

Subpart C requires records to be kept for a minimum of three years from the date of each activity. That includes full charge determinations, technician names, service dates, refrigerant amounts added or removed, calculated leak rates, and ALDS audit results. The full scope of what must be documented is detailed in the recordkeeping requirements under 40 CFR 84.106.

A facility that cannot produce records when an EPA inspector arrives faces a presumption of non-compliance. That presumption shifts the burden — and in penalty negotiations, it removes the most powerful mitigation tool available: showing the agency a contemporaneous, complete paper trail that demonstrates good-faith compliance efforts.

Facilities that use RefriTrak^™ automatically timestamp every refrigerant transaction, leak inspection, ALDS alert, and repair record in a format directly aligned with the data fields EPA inspectors look for. That automatic timestamping creates a contemporaneous, defensible paper trail — the kind that functions as penalty insurance when violations are disputed or penalties are being negotiated. Records created after the fact, or reconstructed from service invoices and memory, carry far less weight in an enforcement proceeding.

Preparation is the other dimension of penalty reduction. Knowing exactly where your documentation is, what it contains, and whether it covers the right time window allows you to respond quickly to an inspection notice rather than scrambling. For a practical guide on what EPA inspectors look for and how to prepare your facility, see how to prepare for an EPA audit under Subpart C.

In EPA enforcement, demonstrated good-faith compliance efforts and complete records consistently produce lower settlement figures than equivalent violations without documentation. The investment in record-keeping infrastructure pays its return most visibly in the penalty negotiation, not during normal operations.
