ALLEGAN COUNTY, MI — On the morning of January 27, 2026, a Quest Liner semi-trailer hauling 26,000 pounds of plastic pellets lost control on icy northbound Interstate 196 at exit 41, northeast of Saugatuck, and overturned. Within minutes, thousands of tiny white pellets — each no larger than a pencil eraser — were rolling across the pavement, down the embankment, and into the Kalamazoo River below.

For the trucking company and the shippers behind the load, the crash was only the beginning of a liability event that, two months later, still has no end in sight.

When the Cargo Becomes the Contamination

The pellets, known in the plastics industry as “nurdles,” are raw polystyrene feedstock used in manufacturing. They measure between 2 and 5 millimeters — roughly the size of a grain of rice — and are extremely difficult to fully recover once they enter a waterway, often requiring long-term cleanup efforts. Polystyrene pellets are typically buoyant or near-neutral in water, meaning they can float, disperse widely, and, over time, may sink as they accumulate sediment or biological growth, becoming embedded and out of reach of conventional cleanup equipment.

The Kalamazoo River makes the situation significantly worse. Portions of the Kalamazoo River are part of a federal Superfund cleanup site — already contaminated with legacy PCB pollution from decades of industrial activity — which can limit how and where sediment can be disturbed during cleanup, depending on regulatory requirements. A full cleanup may not be feasible based on early assessments by the Michigan Department of Environment, Great Lakes, and Energy (EGLE).

As of March 22, 2026, nearly two months after the crash, pellets were still being found along at least 11 miles of highway shoulder, in drainage ditches, in tributaries, and in the river’s floodplain. Wildlife biologists have flagged the risk to fish and birds, which can mistake the small white pellets for fish eggs and ingest them in large quantities — potentially causing organ damage and death.

The three-tier cost picture facing the parties responsible looks like this:

• Emergency Response and Cleanup: Quest Liner contracted two firms — including Young’s Environmental Cleanup, Inc. of Flint — to manage the removal effort. Cleanup of nurdles from a river involves specialized containment, sediment monitoring, and long-term recovery operations far beyond standard roadway cleanup procedures.
• Regulatory Exposure: EGLE issued a formal violation notice to Quest Liner on February 26 — nearly a month after the crash — ordering the company to account for the full volume of material spilled and to submit a remediation plan. Regulators indicated there was a delay between the incident and formal reporting, which was noted in enforcement actions.
• Third-Party Liability: The Kalamazoo River flows into Lake Michigan, a cornerstone of the Great Lakes watershed. Spills that reach navigable waters or federally designated Superfund sites can trigger Natural Resource Damage (NRD) claims from federal and state trustees — a category of liability that can dwarf the direct cleanup costs and persist for years after the initial incident.

The Coverage Gap Nobody Plans For

Most motor carriers and shippers assume their Commercial Auto policy covers them in the event of a crash. For vehicle damage and bodily injury, that’s often true. But when the spilled cargo is a pollutant — and plastic pellets classified as microplastics are increasingly treated as such by state environmental agencies — the coverage picture changes fundamentally.

Standard Commercial Auto policies typically exclude or significantly limit coverage for environmental cleanup, hazardous material remediation, or regulatory response costs. They are vehicle policies, not pollution policies. When cargo enters a waterway and triggers an EGLE enforcement action, response requirement under Superfund, or a Natural Resource Damage assessment, the carrier may face high out-of-pocket costs without specialized pollution coverage.

General Liability (GL) policies often include pollution exclusions, which courts have, in many cases, applied to environmental releases, though interpretations vary by policy language and jurisdiction. Microplastics are increasingly scrutinized by regulators and, in some jurisdictions, treated as pollutants.

The coverage gap isn’t theoretical—incidents like this can expose carriers to significant uninsured costs if appropriate coverage isn’t in place.

The Role of Transportation Pollution Liability

Transportation Pollution Liability (TPL) coverage — typically written as an endorsement to or component of a Contractors Pollution Liability (CPL) policy — exists precisely for this scenario. When a carrier’s vehicle is involved in an incident that releases pollutants into the environment, TPL responds where auto and GL policies stop.

For a spill of this type, TPL coverage addresses:

• Cleanup costs for pollutants released from a vehicle during transit, including cargo that enters drains, ditches, tributaries, and waterways
• Regulatory defense costs for responding to state agency enforcement actions like EGLE violation notices and remediation orders
• Third-party property damage claims from neighboring landowners, downstream users, or municipalities affected by the spill
• Natural Resource Damage exposure — particularly relevant when the release reaches navigable waters or a federally designated Superfund site
• Loading and unloading liability — covering the full transit exposure, not just vehicle-to-vehicle collisions

The cost of a multi-month nurdle recovery operation on a river, combined with regulatory defense and potential NRD liability, can reach six or seven figures depending on the scope and duration of the response. For a carrier without TPL coverage, that exposure sits entirely on the balance sheet.

What the Kalamazoo River Should Be Telling Your Business

The I-196 crash didn’t involve a chemical tanker or a hazardous materials placard. It involved an everyday commodity — plastic pellets used in manufacturing — hauled by a bulk carrier on a routine interstate run. The wintry conditions that caused the crash were unremarkable for a Michigan January. Nothing about this shipment would have appeared, on paper, to carry significant or unusual environmental risk.

This highlights a broader risk. Transportation pollution incidents don’t announce themselves in advance. They arrive on an icy highway at exit 41, and by the time EGLE issues a violation notice, the pellets are already in the sediment of a river where full remediation may be difficult or take years to achieve.

The question isn’t whether a spill like this could happen to a carrier in your network. It’s whether the policy covering that carrier is built for the aftermath.
