The Non-Financial Ledger: What a Gas Release Actually Does to a Body

Anhydrous ammonia is not an abstract regulatory concern. It is a colorless gas that attacks the human body at the point of contact. It dissolves into the moisture of your eyes, your throat, and your lungs, converting instantly into a corrosive alkaline compound that destroys tissue on contact. At low concentrations, it causes coughing and eye irritation. At the concentrations present in a serious industrial leak, it causes pulmonary edema — your lungs fill with fluid. People drown from the inside. At very high concentrations, it can be fatal within minutes.

The workers inside Taylor Farms’ Covington facility process food. They show up to cut vegetables, operate machinery, and keep a supply chain moving. They are not chemical engineers. They are not hazmat technicians. They rely entirely on the systems their employer installs and maintains to tell them when the air they are breathing has become dangerous. That is the whole point of alarm systems. That is the whole point of posted emergency shutdown instructions. That is the whole point of a calibrated detector.

Now consider what the EPA found in August 2022. The ammonia piping in the green bean processing area — where workers are standing — was not labeled to show what was inside the pipes, which direction the substance was flowing, or whether the line was under high or low pressure. If a fitting failed or a line ruptured, a worker would have no immediate way to know what they were dealing with, which exit to use, or which valve to close. The visual alarms outside the machinery room were not marked as ammonia release alarms. A worker seeing a flashing light with no label has no way to know whether it means a refrigeration fault, a fire, or a toxic gas event requiring immediate evacuation.

There were no emergency shutdown instructions posted on the premises. Federal standards specifically require these because the people who need them in a crisis — trained refrigeration staff and emergency responders arriving from outside — need to find them instantly, in the dark, in a panic, possibly while already symptomatic from exposure. The instructions were not there.

The alarms inside the machinery room were set to activate at 50 ppm. Federal engineering standards say 25 ppm is the threshold at which the alarm must trigger. That gap is not a technicality. It is the difference between workers getting a warning while they can still breathe normally and workers getting a warning after they have already been inhaling a toxic concentration for however long it took the level to climb from 25 to 50. Ammonia poisoning does not wait for the paperwork to catch up.

The outdoor emergency stop switch — the one piece of equipment that can cut the entire ammonia system in a crisis, the switch that first responders would run to — had no verified testing record. The company’s own documents say they don’t keep individual records of when it was tested. You cannot assume a piece of life-safety equipment works if you never write down that you checked. And you cannot tell the workers, the neighborhood, or the fire department that arrives in a cloud of gas that you did everything right if the answer to “when did you last test the emergency shutoff” is silence.

This facility sits at 3776 Lake Park Drive in Covington, Kentucky, a city that borders Cincinnati across the Ohio River. A major ammonia release does not stay inside a building. It spreads. The people living near that facility, the people driving past, the first responders who would have been called — none of them had any idea that the safety systems between them and 27,300 pounds of toxic gas had been allowed to quietly degrade.

Legal Receipts: What the Documents Actually Say

The following quotes are taken verbatim from the EPA Consent Agreement and Final Order, Docket No. CAA-04-2024-0310(b), filed August 21, 2024. These are the government’s own findings and the company’s own admissions on the public record.

“The ammonia refrigeration piping around the ammonia/glycol chiller, the evaporator and water chiller, the evaporator and water chiller in the green bean processing area, and evaporators in the shipping area were not adequately labeled to indicate contents, direction of flow, physical state (i.e., liquid or vapor), or pressure level (i.e., high or low).”

EPA Findings of Fact, Section IV.16.a.i — Docket No. CAA-04-2024-0310(b)

• This finding covers multiple locations throughout the facility, including the area where green beans are processed, meaning food production workers were operating in direct proximity to unlabeled ammonia lines.
• Federal and industry standards — ANSI/IIAR 2 (2021), ASME A13.1 (2015), and ANSI/IIAR 9 (2020) — all independently require this labeling. Taylor Farms violated three separate recognized standards simultaneously with the same omission.
• Without labels indicating contents, flow direction, and pressure level, a worker or first responder cannot quickly identify the pipe carrying ammonia, cannot determine which direction to isolate, and cannot assess whether they are dealing with high-pressure liquid or lower-pressure vapor, a distinction critical to predicting how fast and how far a release spreads.

“The anhydrous ammonia visual alarms outside the machinery room were not properly labeled or indicated otherwise as ammonia release alarms.”

EPA Findings of Fact, Section IV.16.a.ii — Docket No. CAA-04-2024-0310(b)

• A flashing light with no label is useless in an emergency. Workers evacuating a building and first responders arriving on scene need to know immediately what kind of alarm they are responding to.
• The required standard, ANSI/IIAR 2 (2021) Section 17.6, states plainly: “Ammonia leak detection alarms shall be identified by signage adjacent to visual and audible alarm services.” This is not a complex engineering requirement. It is a label. Taylor Farms did not put up a label.

“The Facility did not have emergency shutdown documentation posted on the premises of the ammonia refrigeration system.”

EPA Findings of Fact, Section IV.16.a.iii — Docket No. CAA-04-2024-0310(b)

• Federal standards require this documentation to include: step-by-step shutdown instructions, emergency contact names and numbers for facility staff and for local, state, and federal agencies, and the total quantity of ammonia in the system. None of this was posted.
• The specific purpose of posting these instructions is to make them accessible to “trained emergency responders” arriving from outside the facility. An ammonia leak does not pause while a fire department calls headquarters to ask for the shutdown procedure.

“The two ammonia alarms inside the ammonia machine room were set to alarm at 50 ppm. [Federal standard] Detection of ammonia concentrations equal to or exceeding 25 ppm shall activate visual indicators, audible alarms, and provide a notice to a monitored location.”

EPA Findings of Fact, Section IV.16.a.v — Docket No. CAA-04-2024-0310(b)

• The alarms were configured to stay silent at concentrations the federal government already defines as high enough to require an immediate alarm response. Workers inside the machine room could have been exposed to 25 to 49 ppm of ammonia with no audible or visual warning at all.
• Short-term exposure to ammonia concentrations in this range causes eye and respiratory irritation, coughing, and in sensitive individuals, acute bronchospasm. This is not a safe “grace period” before the alarm. It is an exposure window the alarms were supposed to prevent.

“The ammonia detector calibration records provided by the Facility showed that ammonia detectors were only calibrated once in 2021 during April.”

EPA Findings of Fact, Section IV.16.b — Docket No. CAA-04-2024-0310(b)

• Federal standards require ammonia detector calibration at a semiannual frequency, meaning twice per year. One calibration in April 2021 means detectors went without verified accuracy for at minimum the following six months in 2021 and potentially all of 2022 up to the August inspection date.
• An uncalibrated gas detector may read high, low, or not at all. The entire premise of having an automated detection system is that it accurately measures what is in the air. Without calibration, that premise collapses. The alarms were already set too high; the sensors delivering readings to those alarms had no verified accuracy.

“When the inspection team asked for records of tests of the emergency stop switch, the Facility provided a document that states, ‘The facility does not maintain individual records to indicate when the outdoor emergency stop was tested.'”

EPA Findings of Fact, Section IV.16.c — Docket No. CAA-04-2024-0310(b)

• This is not a record that went missing. The facility submitted a document explicitly stating that the records do not exist. They knew the testing records were required. They produced a written statement admitting they do not keep them.
• The outdoor emergency stop switch is the last-resort mechanical intervention available to first responders when an ammonia release is occurring. Its operability cannot be assumed; it must be tested and documented. Federal standards require semiannual testing of emergency shutdown switches. Taylor Farms had no proof any such testing occurred.
• The company signed off on the consent agreement — which includes all of the above findings — and simultaneously certified that all violations had been corrected. The settlement required no admission of wrongdoing, no public apology, and no independent audit of corrective measures.

Societal Impact Mapping: Who Pays the Real Price

Public Health

The documented safety failures at this facility created a persistent, unquantified exposure risk for workers and surrounding residents across a multi-year window.

• Workers in the green bean processing and shipping areas worked alongside unlabeled ammonia lines for an undetermined period before the August 2022 inspection. They had no way to identify which pipes carried the hazardous substance or what to do if one failed.
• The alarm threshold misconfiguration meant that for the entire period the 50 ppm setting was active, any ammonia concentration between 25 and 49 ppm inside the machine room generated no alert. Workers could have been exposed without any automated warning triggering evacuation or ventilation.
• Uncalibrated detectors — confirmed for at least six months in 2021 and potentially longer — meant the facility’s entire automated detection infrastructure was operating without verified accuracy. A sensor reading 0 ppm while actual concentration is 25 ppm is functionally the same as having no sensor.
• The absence of posted emergency shutdown instructions delayed the potential response time of any first responder arriving at the facility during an ammonia event. Every minute of delay in stopping an ammonia release expands the exposure zone and increases the severity of health outcomes for anyone inside or downwind.
• Covington, Kentucky sits on the Ohio River directly across from Cincinnati. A significant ammonia release from this industrial facility could affect residential areas and transit corridors on both sides of the river, a population far larger than the facility’s workforce.
• The missing emergency ventilation control switch outside the machinery room meant that personnel attempting to ventilate a contaminated space during a release could not activate emergency ventilation without entering the potentially contaminated machinery room itself — the exact scenario the external switch exists to prevent.

Economic Inequality

The financial structure of this enforcement outcome reveals a system in which the cost of being caught violating federal safety law is dwarfed by the legal resources corporations deploy to minimize accountability.

• The total civil penalty assessed was $41,432.00. Taylor Farms is the largest fresh-cut produce company in North America by its own public claims. This fine represents a fraction of a fraction of a single day’s revenue for an operation of this scale.
• Taylor Farms retained Gibson, Dunn & Crutcher LLP, headquartered in San Francisco, as legal representation. The firm’s partner billing rates routinely exceed $1,000 per hour. The legal cost of negotiating the settlement almost certainly exceeded the penalty itself.
• The consent agreement was settled without any admission of wrongdoing. From a legal liability standpoint, Taylor Farms paid $41,432, checked a compliance box, and closed the case with a clean slate. No court finding of fault exists.
• The workers who worked beside unlabeled ammonia piping received no compensation, no formal acknowledgment of the risk they were exposed to, and no guaranteed protection beyond the company’s own self-certification that violations were corrected.
• Small businesses operating similar refrigeration facilities face the same federal compliance requirements and the same potential penalties. They do not have access to elite law firms to manage the enforcement process. The cost of compliance and the cost of non-compliance both fall harder on smaller operators than on a corporation the size of Taylor Farms.
• Federal enforcement timelines in cases like this routinely extend two years or more — as this case demonstrates, from the August 2022 inspection to the August 2024 final order. During that window, the corporation continues operating. Workers continue showing up. The safety failures the company is negotiating about may or may not have been corrected in the interim. There is no mandatory immediate remediation requirement in the interim period.

The “Cost of a Life” Metric

The EPA’s penalty framework is designed to remove any economic benefit a company gained from non-compliance. Here is what the numbers actually look like.

What Now: Who to Pressure and What to Demand

Taylor Farms continues operating. The settlement requires no public admission, no independent safety audit, and no worker notification. Accountability here requires external pressure from the people with standing to apply it.

Decision-Makers of Record

• John Mazzei, Secretary and General Counsel, signed the consent agreement on behalf of Taylor Farms Tennessee, Inc. on August 9, 2024. His listed address is 150 Main Street, Suite 400, Salinas, CA 93901. He is the company’s chief legal officer and the signatory to this settlement.
• Peter S. Modlin, Partner at Gibson, Dunn & Crutcher LLP, served as Taylor Farms’ legal representative throughout this proceeding. Contact: One Embarcadero Center Suite 2600, San Francisco, CA 94111-3715.
• The EPA case officers on record are Jordan Noles (Case Development Officer, noles.jordan@epa.gov) and Ellen Rouch (Attorney-Advisor, rouch.ellen@epa.gov), Region 4, Atlanta.

Watchlist: Regulatory Bodies That Have Jurisdiction

• EPA Region 4 (Atlanta): The primary enforcement authority here. They brought this case. They also accepted a settlement that required no independent verification of corrective measures. They can and should be asked: who confirmed the violations were actually fixed, and on what date?
• OSHA (Occupational Safety and Health Administration): Has independent jurisdiction over worker safety at industrial facilities handling hazardous substances. Anhydrous ammonia in quantities above 10,000 pounds triggers OSHA’s Process Safety Management (PSM) standard at 29 CFR 1910.119. The EPA violations documented here almost certainly overlap with PSM requirements. OSHA has not been identified in this document as having taken action.
• Kentucky Labor Cabinet / Department of Workplace Standards: The facility operates in Covington, Kentucky. Kentucky operates its own OSHA-approved state plan. State labor inspectors have independent authority to inspect this facility and issue citations.
• Kenton County Emergency Management (Kentucky): Local emergency management has a direct interest in the safety systems at any facility storing hazardous chemicals above federal threshold quantities. They can request documentation of corrective measures and include the facility in community hazard planning.
• DOJ Environment and Natural Resources Division: Retains the right to pursue criminal sanctions under CAA Section 113(c) for any knowing violations of law. The settlement explicitly preserves this authority.

What You Can Do

• If you work at or near the Taylor Farms Covington facility: You have the right to request a copy of the facility’s current Risk Management Plan, which is a public document registered with the EPA. You also have the right to file a complaint with OSHA if you believe safety conditions remain inadequate. OSHA complaints can be filed anonymously at osha.gov.
• Contact your Kenton County Commissioner: Ask whether the county’s local emergency planning committee (LEPC) has received and reviewed the corrective measures Taylor Farms claims to have implemented. LEPCs are community bodies with a legal right to this information under federal law.
• Demand EPA Region 4 publish follow-up inspection results: The consent agreement states violations “have been corrected” based on the company’s own self-certification. There is no indication of an independent follow-up inspection. File a public records request (FOIA) with EPA Region 4 for any post-settlement inspection records for Docket No. CAA-04-2024-0310(b).
• Support food worker organizing: Taylor Farms workers face conditions that most of the food supply chain workers across North America recognize: high-risk environments, limited workplace voice, and employers whose legal strategy prioritizes minimizing liability over worker safety. Organizations like the United Farm Workers (UFW) and the Food Chain Workers Alliance connect food industry workers with advocacy resources.
• Share this record: This consent agreement is a public federal document. The case number is CAA-04-2024-0310(b). Anyone can look it up. Sharing primary source government documents is one of the most powerful tools available for holding corporations accountable in the court of public opinion, where there are no settlement negotiations and no admission-free exits.
