How Pest Fog Turned Ozone Destruction Into a Business Expense
EPA Region 5 Enforcement Action · Filed July 17, 2025
TL;DR
- Pest Fog Sales Corp., a Texas fumigant company, imported methyl bromide, one of the most ozone-destroying chemicals on Earth, without proper permits or reporting for nearly three years.
- The company brought in over 336,944 kilograms of methyl bromide across 24 shipments between August 2020 and July 2023, making zero required quarterly disclosures to the EPA during that entire stretch.
- One shipment alone, 8,724 kg of methyl bromide, exceeded Pest Fog’s legal import limits outright, a standalone federal violation on top of the reporting blackout.
- The EPA settled with Pest Fog for a civil penalty of $116,826 (about enough to cover 4 months of groceries for 200 families), a sum widely regarded as a slap on the wrist for three years of environmental law-breaking.
- Pest Fog neither admitted nor denied the violations but waived its right to appeal, contest the findings, or challenge the EPA’s authority.
The penalty math in “The Cost of a Life” section reveals exactly how cheap the ozone layer turned out to be, per kilogram, under this settlement.
A Texas fumigant company pumped over 336,000 kilograms of one of the planet’s most banned ozone-destroying chemicals into the supply chain, for three straight years, without filing a single legally required report to the EPA.
The Three-Year Shadow Operation
Pest Fog Sales Corp. operates out of Corpus Christi, Texas, and its primary business is importing and selling methyl bromide, a fumigant so destructive to the stratospheric ozone layer that the entire world agreed in the Montreal Protocol to phase it out. Under U.S. law, importing methyl bromide requires holding specific government-issued allowances: Critical Use Allowances (CUAs) or Essential Use Allowances, both of which exist precisely because regulators recognized this chemical is dangerous enough to need strict controls on every kilogram.
From August 2, 2020 through July 19, 2023, Pest Fog executed 24 separate methyl bromide import shipments. Federal law required the company to submit detailed quarterly reports to the EPA Administrator for every one of those shipments, disclosing quantities, ports of entry, countries of origin, allowance usage, and sales records. Pest Fog submitted zero of those reports.
The EPA’s own records confirm 24 separate violations of the federal reporting requirement, one for each quarter during which the company stayed silent. The agency did not discover the pattern through a tip or a corporate confession. The EPA issued a formal Finding of Violation on May 30, 2024, nearly a year after the last illegal shipment landed.
They Didn’t Just Skip Paperwork. They Broke the Import Caps Too.
The reporting silence was compounded by a direct import violation. Shipment MK855385557, dated November 13, 2020, carried 8,724 kilograms of methyl bromide that exceeded Pest Fog’s unexpended allowances. This was not a technicality. Every kilogram of methyl bromide beyond the legal limit constitutes, by federal regulation, a separate violation. The EPA found that one shipment pushed the company over its legal ceiling and charged it with a standalone breach of the import controls at 40 C.F.R. § 82.4(d).
Federal regulations are explicit: “Every kilogram of excess importation… constitutes a separate violation of this subpart.” Pest Fog imported 8,724 kilograms over its limit. That is, in theory, 8,724 separate violations compressed into a single line item in the settlement agreement.
That is eleven quarters. Eleven chances to come clean. Zero reports filed.
The Non-Financial Ledger: What a Depleted Ozone Layer Actually Costs You
The settlement document tallies one number: $116,826 (roughly the cost of about two luxury pickup trucks). It does not tally the kilograms of ozone destroyed. It does not tally the UV-B radiation that passed through a thinned stratospheric shield because companies like Pest Fog decided that importing a globally controlled chemical without disclosing a single shipment for three years was an acceptable business practice. The financial fine is a footnote. The atmospheric damage is the headline.
Methyl bromide is not a generic pesticide. It is a Class I, Group VI controlled substance under federal law, placed in that category because science demonstrated conclusively that it destroys the stratospheric ozone layer far more aggressively than most other chemicals. The ozone layer is the only thing standing between life on Earth and the full fury of solar UV-B radiation. Skin cancers, cataracts, immune suppression, marine ecosystem collapse from phytoplankton die-offs, agricultural yield crashes: these are the documented downstream consequences of ozone depletion. Every unauthorized kilogram of methyl bromide released into the atmosphere without regulatory accounting chips away at a shared global resource that every human being on the planet depends on, without ever being asked.
Pest Fog’s business model depends on a chemical that the global community decided, via international treaty, to eliminate. The Montreal Protocol exists precisely because previous generations of industry treated the atmosphere as a free dumping ground, and scientists spent decades documenting the resulting hole above Antarctica. The allowance system, the quarterly reports, the kilogram-by-kilogram accounting: all of it exists because regulators learned, the hard way, that industry cannot be trusted to self-regulate substances this dangerous. Pest Fog’s three years of silence was a direct rejection of that lesson.
The 24 missing quarterly reports were not a clerical failure. Each report was supposed to contain the quantity imported, the port of entry, the country of origin, the allowance type expended, copies of bills of lading and invoices, and written certifications about how the methyl bromide would be used. These are records designed to let regulators trace every kilogram of a planet-harming chemical from ship to soil. By filing none of them, Pest Fog made that tracing impossible. Citizens, scientists, and enforcement agencies were left completely in the dark about where 336,944 kilograms of an ozone-destroying chemical went, and who ultimately used it. That is a betrayal of every community located downwind, downstream, or simply beneath the sky.
Legal Receipts: The Documents Don’t Lie
Societal Impact Mapping
Environmental Degradation
Methyl bromide is classified as a Class I, Group VI controlled substance under the EPA’s stratospheric ozone protection regulations at 40 C.F.R. Part 82. Class I substances are the most dangerous category, the chemicals determined to cause the greatest harm to the ozone layer. The regulatory framework governing methyl bromide, including the allowance system and the quarterly reporting regime, exists precisely because every kilogram released into the atmosphere without accountability represents a direct, measurable contribution to ozone depletion.
The allowance system is the EPA’s primary mechanism for tracking and capping how much of this chemical enters the U.S. supply chain. When Pest Fog filed zero quarterly reports across 24 quarters and imported 8,724 kilograms beyond its permitted ceiling, it removed those quantities from the regulatory ledger entirely. There is no public record of where those specific kilograms landed, how they were applied, or whether they were used for the legally permitted quarantine and preshipment applications that represent the primary remaining legal use of methyl bromide. The chemical simply vanished from the accountability chain.
The Montreal Protocol, the global agreement underpinning domestic law here, phased out most methyl bromide use effective January 1, 2005. The critical use and quarantine exemptions Pest Fog was supposed to hold allowances for exist as narrow, tightly managed exceptions to that global ban. Three years of invisible importing undermines the integrity of those exemptions for every other compliant actor in the supply chain, and for every nation that has signed and honored the Protocol.
Public Health
Methyl bromide is acutely toxic to humans. The fumigant is used specifically because it kills living organisms at the cellular level. Applicators and nearby communities face documented risks of neurological damage, respiratory injury, and in acute exposure cases, death. The EPA’s allowance and reporting system is not just an environmental accounting mechanism; it is a public health surveillance tool. Quarterly reports must include records of who received the methyl bromide, in what quantities, and for what certified use. When Pest Fog went dark for three years, health authorities lost visibility into the distribution of a toxic substance across the supply chain.
The missing certifications are particularly significant. Federal regulations required Pest Fog to collect written certifications from every purchaser confirming that methyl bromide sold for critical or quarantine use would only be used for those purposes, and would not be diverted or resold. Without the quarterly reports, those certifications were never submitted to the EPA. There is no way to independently verify, from the public record, that the chemical moved only to licensed, compliant applicators and not into unregistered fumigation operations where worker and community exposure controls may have been absent entirely.
Economic Inequality
The $116,826 penalty ($116,826, roughly what a minimum wage worker in Texas earns over five and a half years of full-time work) resolves three years of violations and 24 separate reporting failures. For a company that imports tens of thousands of kilograms of methyl bromide per shipment at commercial fumigant market prices, this penalty is a rounding error. It functions less as a punishment and more as the cost of doing business outside the rules.
The communities bearing the greatest environmental and public health burden from ozone-depleting chemicals are disproportionately low-income communities and communities of color located near agricultural and fumigation operations where methyl bromide is applied. Those communities had zero visibility into Pest Fog’s operations during the three-year reporting blackout. The EPA had no data. Regulators could not respond to what they could not see. The regulatory system that is supposed to protect the most exposed communities was functionally disabled by the company’s silence, and the consequence for that silence was a fine smaller than the annual salary of one entry-level federal employee.
The “Cost of a Life” Metric
The total civil penalty the EPA settled for after Pest Fog ran a three-year, 24-shipment, 336,944 kg methyl bromide operation with zero required federal disclosures.
$0.35
The effective penalty rate per kilogram of methyl bromide imported across all 24 shipments. Less than the cost of a single piece of gum. That is what the ozone layer was worth, per kilogram, under this settlement.
$116,826
(Enough to cover approximately 5.5 years of full-time minimum wage work in Texas, or roughly 4 months of groceries for 200 families.)
Pest Fog waived its right to appeal. The fine is final. The atmosphere still carries every kilogram.
What Now?
Corporate Roles Named in This Action
- Pest Fog Sales Corp., Respondent, Corpus Christi, Texas. Importer and seller of methyl bromide.
- Michael D. Harris, Division Director, EPA Region 5 Enforcement and Compliance Assurance Division. Signed the settlement on behalf of the EPA on July 16, 2025.
Watchlist: Who Oversees This
- U.S. Environmental Protection Agency (EPA) — Region 5 Air Enforcement and Compliance Assurance Branch. Primary regulator. Contact: R5airenforcement@epa.gov
- EPA Stratospheric Protection Division — Administers the methyl bromide allowance system under the Montreal Protocol and 40 C.F.R. Part 82.
- U.S. Department of Justice (DOJ) — Joint authority with EPA on whether this matter warranted criminal referral. It did not result in criminal charges.
- U.S. Customs and Border Protection (CBP) — The entry data that documented each of Pest Fog’s 24 shipments originated from customs records. CBP cooperation is essential to detecting future violations.
- Internal Revenue Service (IRS) — Required to receive Form 1098-F from the EPA reporting the settlement, per federal tax law.
The Maximum Penalty They Avoided
Federal law permits the EPA to seek civil penalties of up to $124,426 per day per violation ($124,426 per day, enough to wipe out the median American household’s net worth in about 12 hours) for future violations of this settlement. The fact that Pest Fog settled for $116,826 total, across three years and 25 distinct violations, shows how enormous the gap is between what the law allows and what enforcement agencies actually collect.
What You Can Do Right Now
File public comments with the EPA demanding that methyl bromide enforcement penalties be calculated per kilogram of violation, not settled as flat-rate fines. Contact your congressional representatives and demand oversight hearings on the EPA’s use of consent agreements that allow corporations to “neither admit nor deny” violations of planetary protection laws. Support environmental justice organizations in agricultural regions where fumigant overuse and under-reporting most directly harm farmworkers and rural communities of color. Local food sovereignty groups, farmworker advocacy networks, and climate justice coalitions are the organizations doing the ground-level work that federal enforcement agencies deprioritize. Find them. Fund them. Show up.
