The Kroger refrigerant lawsuit actually refers to two separate matters. In April 2026, the country’s largest supermarket chain reached a proposed settlement with the U.S. Department of Justice and the Environmental Protection Agency to resolve nearly a decade of alleged Clean Air Act violations tied to refrigerant leaks at its stores, agreeing to a $2.5 million civil penalty and roughly $100 million in equipment upgrades.1U.S. Department of Justice. Kroger Agrees to Settlement Reducing Ozone-Harming Emissions at Grocery Stores Nationwide A year earlier, a Michigan jury handed down a $76.7 million verdict against Kroger to a pipefitter whose hands were destroyed when a refrigerant line ruptured at a Bloomfield Township store.2Expert Institute. $76 Million Verdict for Pipefitter Injured in Kroger Explosion
What the Federal Case Alleged
Federal regulators alleged that between 2014 and 2023, Kroger failed to promptly repair leaks of R-22 refrigerant from commercial refrigeration equipment and failed to maintain the service records the Clean Air Act requires.1U.S. Department of Justice. Kroger Agrees to Settlement Reducing Ozone-Harming Emissions at Grocery Stores Nationwide R-22, also called HCFC-22, is an ozone-depleting hydrochlorofluorocarbon. New production and import were phased out in the United States in 2020, and while existing equipment can still run on reclaimed supplies, venting the chemical is illegal.3U.S. Environmental Protection Agency. Phaseout of Ozone-Depleting Substances
EPA inquiries launched in 2018 and 2019 identified 14 commercial refrigeration appliances and two industrial process refrigeration units that exceeded the pre-2019 leak rate threshold of 35 percent without required corrective action, plus six additional commercial units that broke the stricter post-2019 threshold of 20 percent. The agency also documented 17 recordkeeping and reporting failures.4Grocery Dive. Kroger to Pay $2.5M in Fines, $100M for Appliance Upgrades Due to Refrigerant Leaks
Under Section 608 of the Clean Air Act, owners of commercial refrigeration systems holding 50 or more pounds of ozone-depleting refrigerant must repair leaks within 30 days once the system’s annual leak rate crosses 20 percent. If repairs won’t bring the rate down, the owner has 30 days to develop a retrofit or retirement plan and one year to finish it.5U.S. Environmental Protection Agency. Stationary Refrigeration Leak Repair Requirements
The scale is worth pausing on. As of April 2026, Kroger reported operating 24,627 commercial refrigeration and comfort cooling appliances across 2,734 stores subject to federal refrigerant rules.6The Charlotte Observer. Kroger Settlement Addresses Clean Air Act Violations The settlement covers every Kroger-owned banner nationwide, including Harris Teeter, Smith’s, and Ralphs, wherever refrigeration equipment exceeds 50 pounds.
What Kroger Agreed To
The proposed consent decree, filed as United States v. The Kroger Co., Civil Action No. 26-cv-00421, was lodged in the U.S. District Court for the Southern District of Ohio on April 29, 2026.7Federal Register. Notice of Lodging of Proposed Consent Decree Under the Clean Air Act It requires Kroger to:
- Pay a $2.5 million civil penalty for past violations.
- Retrofit or replace 600 large commercial refrigeration systems now using CFC or HFC refrigerants, transitioning them to EPA-approved alternatives such as the A2L refrigerants R-32 and R-454B.4Grocery Dive. Kroger to Pay $2.5M in Fines, $100M for Appliance Upgrades Due to Refrigerant Leaks
- Spend an estimated $100 million on those upgrades and related compliance work.
- Implement a company-wide refrigerant management system to prevent and repair leaks.
- Keep its corporate-wide average leak rate at or below 9.5 percent per year, down from a reported 10.6 percent.1U.S. Department of Justice. Kroger Agrees to Settlement Reducing Ozone-Harming Emissions at Grocery Stores Nationwide
The decree also requires Kroger to maintain the service documentation federal regulations mandate for systems containing ozone-depleting substances. Full compliance releases the company from past civil liability for the specific violations covered. Kroger did not admit liability.6The Charlotte Observer.

Where the Settlement Stands Now
The proposed consent decree was published in the Federal Register on May 6, 2026, opening a 30-day public comment window that closed on June 5, 2026.7Federal Register. Notice of Lodging of Proposed Consent Decree Under the Clean Air Act The DOJ must then submit the decree to the court for final approval. As of late June 2026, the docket showed Kroger’s attorneys had filed notices of appearance in May but no further substantive filings or recorded public comments had been entered.8Cincinnati Enquirer.

How This Ranks Against Other Grocery Refrigerant Cases
The Kroger deal is the largest refrigerant enforcement action ever brought against a grocery retailer, on both the penalty and the required spending. Earlier cases in the same enforcement program were smaller by an order of magnitude:
- Safeway (2013): $600,000 penalty and about $4.1 million in compliance costs across 659 stores, with a leak rate target dropping from 25 percent to 18 percent by 2015.9U.S. Environmental Protection Agency. Safeway Inc. Clean Air Act Settlement
- Trader Joe’s (2016): $500,000 penalty and an estimated $2 million in compliance costs across 453 stores, and the first such settlement to reach HFC leaks specifically for greenhouse gas reasons.10U.S. Environmental Protection Agency. Trader Joe’s Company Clean Air Act Settlement
- Southeastern Grocers (2019): $300,000 penalty and roughly $4.2 million in compliance costs covering Winn-Dixie, Harveys, BI-LO, and Fresco y Más.11WJCT News. EPA Agrees to $4.5M Emissions Settlement With Jax-Based Southeastern Grocers
Kroger’s $2.5 million penalty is more than four times the largest previous fine, and the $100 million equipment obligation eclipses every earlier compliance cost combined. Its 9.5 percent leak rate cap is also the most aggressive on record: Safeway’s target was 18 percent, Trader Joe’s 12.1 percent, and Southeastern Grocers’ 17 percent.
The Michigan Pipefitter Verdict
The federal enforcement action is distinct from the personal injury case that produced Kroger’s $76.7 million verdict in June 2025. On February 1, 2022, Brian Mierendorf, a 37-year-old HVAC technician and pipefitter, was working on refrigeration lines at a Kroger in Bloomfield Township, Michigan, when a line ruptured. High-pressure R-22 sprayed onto his hands as he tried to cap the leak to protect customers inside the store.12Detroit Free Press. Jury Awards Man $75 Million After Kroger Store Incident
Mierendorf suffered severe chemical burns and underwent 25 surgeries. Most of both hands were eventually amputated.13MLive. Kroger Ordered to Pay $75M to Man Who Lost Hands in Chemical Explosion at Michigan Store He and his wife, Heather Mierendorf, sued Kroger Co. of Michigan in Oakland County Circuit Court, alleging negligence in the maintenance and safety of the refrigeration system. His attorney called the equipment “a ticking time bomb.”2Expert Institute. $76 Million Verdict for Pipefitter Injured in Kroger Explosion At trial, the plaintiff argued Kroger failed to produce required maintenance, repair, or inspection records for the system and turned over only a partial incident report two years after the event.14ClickOnDetroit. Oakland County Jury Awards Nearly $77M to Man Who Lost Fingers in Kroger Chemical Explosion Kroger’s defense argued that Mierendorf failed to follow proper procedures. The jury rejected that argument.
On June 17, 2025, after roughly four hours of deliberation, jurors found Kroger solely liable and awarded the Mierendorfs $76.7 million: more than $63 million to Brian Mierendorf for medical expenses, lost wages, and pain and suffering, and more than $13 million to Heather Mierendorf for loss of consortium and companionship.2Expert Institute. $76 Million Verdict for Pipefitter Injured in Kroger Explosion The award has been described as likely the largest premises liability verdict in Michigan history. Kroger had previously appealed a pretrial denial of its motion for summary disposition to the Michigan Court of Appeals, and that appeal could affect the final payout.
What It Means for Kroger’s Refrigeration Fleet
The 600 systems covered by the consent decree are a fraction of the more than 24,000 regulated appliances Kroger operates. The Environmental Investigation Agency’s 2024 scorecard reported that Kroger uses ultra-low global warming potential refrigerants in fewer than one percent of its stores and most of its distribution centers, and does not publicly disclose a formal leak reduction goal. Its reported leak rate stood at 10.6 percent, just above the new 9.5 percent ceiling the settlement will impose.15Facilities Dive. Refrigerant Leaks to Cost Kroger $2.5M in Fines, $100M for Appliance Upgrades Whether the mandated $100 million in upgrades marks the start of a broader fleet overhaul, or a bounded compliance project confined to the systems named in the decree, will play out over the two- to three-year implementation window.
