TL;DR
Hudsonville Creamery, maker of Hudsonville Ice Cream, operates a large ammonia refrigeration system at its Holland, Michigan manufacturing plant. Ammonia refrigeration is common in food manufacturing but requires strict safety protocols under the EPA’s Risk Management Program because an accidental ammonia release can be toxic and even fatal in high concentrations. When EPA inspected the facility in May 2022, it found that safety hazard recommendations from a 2019 analysis weren’t completed until 2022, a February 2021 compliance audit finding sat uncorrected for 15 months, an ammonia leak in December 2021 was investigated by a contractor but Hudsonville never documented that corrective actions were actually taken, and the company had no system to evaluate whether its contractors were fulfilling their safety obligations. These failures were not hypothetical risks. An actual ammonia leak occurred between two of these violations. Hudsonville agreed to pay $100,000 to settle the case and has since taken corrective steps.
Industrial safety programs exist because people die in preventable accidents. Delayed corrective action is a choice, and communities near these facilities bear the consequences.
⚠️ Core Allegations
Four Risk Management Program Violations
Process hazard, compliance audit, incident investigation, contractor oversight · 7 points
▼
| 01 | Hudsonville operates an ammonia refrigeration system exceeding the 10,000-pound federal threshold quantity, requiring compliance with the most demanding tier of EPA’s Chemical Accident Prevention Provisions, known as Program 3. | high |
| 02 | A Process Hazard Analysis conducted in December 2019 generated recommendations for corrective actions. Hudsonville did not complete these recommended actions until 2022, years later, in violation of the requirement to resolve recommendations in a timely manner and complete actions as soon as possible. | high |
| 03 | A compliance audit in February 2021 identified missing design codes and standards for the original ammonia system. The recommended corrective action was not completed until May 2022, almost 15 months later, in violation of the requirement to promptly document and correct deficiencies. | high |
| 04 | On December 1, 2021, an ammonia leak occurred in the facility’s mechanical room. A contractor investigated and produced a report with corrective recommendations, including checking isolation valves and implementing three additional safety processes. | high |
| 05 | Despite the December 2021 ammonia leak and the contractor’s investigation report, Hudsonville had no documented system to promptly address and resolve incident report findings and recommendations. The company also failed to document that the corrective actions were actually completed. | high |
| 06 | At the time of the May 2022 EPA inspection, Hudsonville had no plan to evaluate the performance of contractors who worked in the covered process area. This means there was no formal mechanism to verify that contractors responsible for safety-critical work were doing it correctly. | med |
| 07 | Hudsonville expanded its ammonia refrigeration system twice between 2020 and 2022, adding a total of 27,624 additional pounds of anhydrous ammonia. Each expansion increased the facility’s regulated process size and safety obligations, which were not being consistently met. | med |
🏭️ Regulatory Failures
How safety oversight broke down over time · 4 points
▼
| 01 | Hudsonville’s ammonia refrigeration system has been operating since approximately 2004 with an initial charge of 23,609 pounds of anhydrous ammonia. The system was subject to Program 3 Risk Management requirements from the start, yet multiple compliance gaps persisted into the 2020s. | med |
| 02 | The EPA found that recommended actions from a 2019 hazard analysis were completed in 2022, meaning the company sat on safety recommendations for at minimum two to three years. This pattern of delay is precisely what chemical safety regulations are designed to prevent. | high |
| 03 | An ammonia leak occurred in December 2021, between a compliance audit that identified deficiencies in February 2021 and the corrective actions that were not completed until May 2022. The timeline shows that safety gaps identified by Hudsonville’s own auditing were still unresolved when an actual release occurred. | high |
| 04 | The EPA and the Department of Justice jointly determined that this matter was appropriate for administrative penalty assessment even though the alleged violations occurred more than one year before the proceeding began, underscoring the seriousness with which federal authorities view these failures. | med |
☣️ Public Health and Safety
What anhydrous ammonia risks mean for workers and communities · 4 points
▼
| 01 | Anhydrous ammonia is a federally regulated toxic substance because accidental releases can cause severe respiratory injury, chemical burns, and death at high concentrations. The 10,000-pound federal threshold that triggers Program 3 requirements reflects the scale of potential public harm from a catastrophic release. | high |
| 02 | Hudsonville’s Holland, Michigan facility operates in a populated area. A significant ammonia release from a system holding over 50,000 pounds combined could require community evacuation and cause injuries well beyond the facility’s property line. | med |
| 03 | Workers in the facility’s mechanical room, including the contractors cited in the inspection findings, faced elevated risk from the absence of verified corrective actions after the December 2021 leak and from working under a contractor safety program that nobody was monitoring. | high |
| 04 | Process Hazard Analysis recommendations and compliance audit findings are generated specifically to prevent accidental releases. Delaying their implementation for months or years means choosing to operate with known, documented safety deficiencies. | high |

💬 From the Legal Record
QUOTE 1The process hazard analysis requirementCore Allegations
“The owner or operator shall establish a system to promptly address the team’s process hazard analysis findings and recommendations; assure that the recommendations are resolved in a timely manner and that the resolution is documented; document what actions are to be taken; complete actions as soon as possible.”
💡 This is the standard Hudsonville violated by sitting on its 2019 PHA recommendations until 2022. “As soon as possible” is the operative phrase.
QUOTE 2The December 2021 ammonia leakRegulatory Failures
“On December 1, 2021, an ammonia leak occurred in the mechanical room. Hudsonville’s contractor’s investigation report described the incident and provided recommendations of corrective actions… However, there is no documentation that Hudsonville has a system to promptly address and resolve incident report findings and recommendations.”
💡 An actual ammonia release happened. A contractor told Hudsonville what to fix. Hudsonville cannot demonstrate it followed through. That is the core failure here.
QUOTE 3The missing contractor oversight systemCorporate Accountability Failures
“At the time of the 2022 inspection, Hudsonville did not have a plan to evaluate the performance of contractors.”
💡 Contractors perform safety-critical work around 50,000+ pounds of toxic ammonia. Hudsonville had no system to verify they were doing it right.
QUOTE 4The long delay in correcting a known audit findingRegulatory Failures
“Hudsonville completed this action on May 11, 2022, almost 15 months later.”
💡 The deficiency was identified in February 2021. The fix happened in May 2022. An ammonia leak occurred in December 2021, in the middle of that 15-month gap.
💬 Commentary
Why is anhydrous ammonia so tightly regulated?▼
Anhydrous ammonia is a colorless gas that is highly toxic at concentrations achievable in an indoor facility release. Exposure causes severe burns to the eyes, skin, and lungs and can be fatal at high concentrations. It is widely used in industrial refrigeration, including in food manufacturing and cold storage, which puts it in proximity to workers and, in the event of a large-scale release, nearby residential areas. The EPA’s Risk Management Program exists specifically to reduce the frequency and consequences of accidental releases of substances like this.
Why is it concerning that the corrective actions from the December 2021 leak were not documented?▼
When an ammonia leak occurs, the follow-up investigation identifies specific mechanical failures and specific fixes. If a company does not formally document that those fixes were implemented, it has no evidence they were done at all. The system may still have the same vulnerability that caused the first leak. Documentation requirements are not bureaucratic formalities: they are the mechanism by which accountability is maintained over time and by which regulators can verify that a facility is actually safe, rather than just claiming to be.
Hudsonville has since made corrections. Doesn’t that matter?▼
Yes, and the EPA acknowledged Hudsonville’s cooperation in the settlement. The corrective actions taken between 2021 and 2025 are listed in the consent agreement and include assigning qualified professional oversight, updating operating procedures, procuring compliance tracking software, and enhancing employee training. These are meaningful improvements. The penalty and the public record, however, serve an accountability and deterrence function: companies operating with known safety gaps near workers and communities should face consequences, and the public should know what those gaps were.
What can I do to prevent this from happening again?▼
The EPA’s RMP database allows the public to look up Risk Management Plans for facilities in your area. If you live or work near an industrial facility, you can find out whether it holds regulated chemicals and what emergency response plans are in place. You can contact your local emergency planning committee to understand community notification systems for chemical releases. Supporting fully funded EPA inspection programs is critical, as the inspection that uncovered these violations happened years after the safety gaps first appeared. If you are an employee at an industrial facility, OSHA and EPA both have confidential complaint mechanisms that allow workers to report safety violations without fear of retaliation.
