The Smitty’s Supply lawsuit is actually several overlapping legal actions stemming from an August 22, 2025 explosion at the company’s Roseland, Louisiana lubricant plant that spilled up to 13 million gallons of oil and chemicals into the Tangipahoa River. The largest is a joint civil enforcement action by the EPA and the Louisiana Department of Environmental Quality seeking more than $1 billion in fines. A federal criminal investigation is running alongside it, and dozens of residents and contractors have filed their own suits over health effects and property damage.
What Happened at the Roseland Plant
An explosion at Smitty’s Supply on August 22, 2025 ignited a fire that burned for two weeks. No one was killed or injured in the blast itself, but authorities ordered a mandatory evacuation within a one-mile radius, and residents in Roseland and neighboring Amite reported a black, oily substance falling with the rain and coating cars, roofs, and outdoor furniture.1FOX 8 Live.

Millions of gallons of oil, lubricants, and firefighting water flowed into ditches and the Tangipahoa River, contaminating roughly 47 miles of waterway downstream toward Lake Pontchartrain.2Louisiana Illuminator. Smitty’s Explosion A Louisiana state wildlife report documented at least 74 wild animals recovered from contaminated areas, 59 of them covered in or having ingested the oily substance, with eight found dead, including turtles and an alligator. Residents also reported losing cattle, horses, and pets.3The Lens. Louisiana Town Fights for Relief After a Billion-Dollar Oil Disaster
The EPA took over the emergency response on August 24, 2025 after Smitty’s withdrew from cleanup, citing financial difficulties. Federal crews deployed 269 personnel at the peak, and cleanup costs climbed from about $6 million in late August to roughly $40 million by early October 2025.4Capital B News.

The Billion-Dollar Federal-State Lawsuit
On November 5, 2025, the EPA and the Louisiana Department of Environmental Quality filed a joint civil enforcement action in the U.S. District Court for the Eastern District of Louisiana, United States of America v. Smitty’s Supply, Inc., case number 2:25-cv-02271.6CourtListener. United States of America v. Smitty’s Supply, Inc. The complaint alleges violations of the federal Clean Water Act, the Louisiana Water Control Law, and Louisiana water pollution control regulations, covering not only the August 2025 disaster but a pattern of violations reaching back five years.7News From the States. EPA Lawsuit Could Extract $1B From Smitty’s Supply; Money for Neighbors Uncertain
The Clean Water Act allows the EPA to seek up to $7,093 per barrel of oil discharged, which could reach $1.8 billion if a court finds gross negligence or willful misconduct. Louisiana state penalties add $32,500 per violation per day. Combined, the governments are seeking fines that could exceed $1 billion. The suit also asks the court to require Smitty’s to take all appropriate measures to prevent future spills.7News From the States. EPA Lawsuit Could Extract $1B From Smitty’s Supply; Money for Neighbors Uncertain
The case is still in its early stages. Smitty’s Supply requested multiple extensions of time before filing its answer to the complaint on May 12, 2026. A motion to stay the proceedings was filed the following day and granted on May 18, 2026.6CourtListener. United States of America v. Smitty’s Supply, Inc.
On April 21, 2026, the Louisiana Environmental Action Network and Northshore River Watch, represented by Waltzer Wygul & Garside, moved to intervene. The groups say their members live in Tangipahoa Parish and own contaminated land. They are not seeking money for themselves but want a seat at settlement negotiations to prevent what they call a weak deal with minimal fines, and to push for a comprehensive remediation plan covering the 47 miles of downstream contamination.8Louisiana Illuminator.

The Federal Criminal Investigation
A separate criminal track is moving in parallel. On November 18 and 19, 2025, agents from the EPA’s Criminal Investigation Division, the FBI, and the Louisiana State Police executed a search warrant at the Roseland facility, forcing a three-hour halt to cleanup operations.9Louisiana Illuminator. Search Warrant at Smitty’s Supply
The EPA has confirmed an “ongoing regulatory investigation” but declined to say what agents were looking for, citing a Freedom of Information Act exemption for records whose release could interfere with enforcement proceedings. As of early 2026, no criminal charges or indictments have been announced. The EPA’s criminal division typically investigates illegal disposal of hazardous waste, unauthorized discharges, and related offenses such as false statements and fraud.9Louisiana Illuminator.

Hazardous Waste Findings and PFAS Contamination
A joint EPA-LDEQ inspection of the site in October 2025 found roughly 250 damaged containers, more than 200 spills, and more than 300 unlabeled or unidentified containers on the property. In January 2026, the EPA entered an administrative compliance order on consent addressing alleged violations of the Resource Conservation and Recovery Act, including failure to make accurate hazardous waste determinations, failure to operate the facility to minimize releases, failure to carry out the required contingency plan, failure to keep containers in good condition, and failure to manage universal hazardous waste. Smitty’s was given 60 days to fix the problems.10U.S. Environmental Protection Agency. EPA Requires Smitty’s Supply to Address Alleged Hazardous Waste Violations
In March 2026, lab reports released by LDEQ showed at least 24 different PFAS compounds in stormwater discharge samples collected from the site between October 2025 and January 2026. One sample measured 13,000 parts per trillion of perfluorooctane sulfonic acid, roughly 3,250 times higher than EPA drinking water standards. PFOA and PFHxS registered at 67 and 308 times above EPA recommendations, respectively. Arsenic, lead, and chromium were also detected.11Louisiana Illuminator. High PFAS Levels in Smitty’s Supply Discharges Smitty’s has said the PFAS came from firefighting foam used by responders, not from company products. Environmental experts have disputed that, noting PFAS is commonly found in industrial lubricants and oils of the kind Smitty’s processed.12News From the States.

PFAS compounds do not break down naturally, accumulate in fish tissue and the human body, and are linked to cancer, liver damage, and hormone disruption.13WDSU. New Lab Reports Show High Levels of Forever Chemicals at Smitty’s Supply
Lawsuits From Residents and Contractors
Private suits began within days of the explosion. On August 26, 2025, the Berniard Law Firm of New Orleans filed a class-action complaint in the 21st Judicial District Court in Tangipahoa Parish on behalf of plaintiff Sterling R. Jackson and a proposed class of more than 100 people. The suit alleges negligence in facility maintenance, failure to warn residents of hazards, and engaging in an abnormally dangerous activity. It seeks damages for headaches, respiratory problems, skin and eye irritation, emotional distress, and property damage from soot and debris.14Legal Newsline.

Smitty’s Suit Against Its Boiler Suppliers
Smitty’s has filed litigation of its own. In October 2025, the company sued in the 21st Judicial District Court, blaming the explosion on a defective thermal fluid heater manufactured by Fulton Boiler Works Inc. of New York and negligently installed and maintained by J&M Boiler Combustion Control Services of Baton Rouge. An attorney for Smitty’s said the company operated the equipment as intended and inspected it regularly. J&M’s president, Jean Window, disputed that account, saying her company had not worked with Smitty’s for several years.16FOX 8 Live.

The Company’s Prior Violation Record
Federal records show Smitty’s had been cited for Clean Water Act violations in every quarter since April 2022. Between May 2022 and August 2025, the company self-reported 230 instances of exceeding its permitted discharge limits for pollutants including organic material, fecal coliform, and carbon.2Louisiana Illuminator. Smitty’s Explosion In one reporting period, organic carbon levels were nearly 2,000% above the allowable limit, and oil and grease levels were 416% over.17FOX 8 Live. Smitty’s Supply Inc. Has History of EPA Violations, Records Show
The enforcement history the governments are relying on includes:
- $194,772 in Clean Water Act penalties across four formal EPA enforcement actions in the five years before the explosion.18Louisiana Illuminator. Smitty’s Supply Compliance Record
- A $250,000 state settlement in December 2023 resolving Resource Conservation and Recovery Act violations tied to used oil handling, generator requirements, and inspection failures.18Louisiana Illuminator. Smitty’s Supply Compliance Record
- A $45,000 EPA penalty in 2023 for violations of the Emergency Planning and Community Right-to-Know Act.18Louisiana Illuminator. Smitty’s Supply Compliance Record
The Roseland facility was classified as a Significant Non-Complier under RCRA for 12 consecutive quarters, a designation lifted in December 2023 after the company settled. Regulators also determined after the August 2025 disaster that Smitty’s lacked a required Spill Prevention, Control and Countermeasure Plan and had not maintained an adequate Facility Response Plan.2Louisiana Illuminator.

A Separate Case: The Tractor Hydraulic Fluid Settlement
One earlier case involving Smitty’s is unrelated to the explosion and often confused with it. In October 2024, Smitty’s Supply and CAM2 International reached a $31.9 million settlement to resolve a multidistrict consumer fraud lawsuit over their “303” tractor hydraulic fluid products. That litigation alleged the companies marketed hydraulic fluid under an obsolete “303” specification using poor-quality base oils, waste oil, and diluted additive packages. A Missouri federal judge preliminarily approved the settlement on October 3, 2024, with final approval scheduled for March 2025. Class members who bought certain Super S or CAM2 303 products since December 2013 could file claims for per-unit payments and up to $1,000 in equipment damage without proof of costs.19ClassAction.org. $32M Smitty’s CAM2 Tractor Hydraulic Fluid Settlement Preliminarily Approved by Court That case has nothing to do with the Roseland spill or the pending federal-state enforcement action.
