Illegal Dumping in Washington State: Fines, Jail Time, and Cleanup Costs

Penalties for illegal dumping in Washington State scale with how much waste you dump and what kind it is. Discarding one cubic foot or less of ordinary waste is a civil infraction with a fine but no criminal record. Anything above that is a crime: a misdemeanor up to ten cubic yards, and a gross misdemeanor at ten cubic yards or more, carrying up to 364 days in jail and a $5,000 fine. Every criminal conviction also comes with cleanup restitution set at two to four times the actual cost of cleaning up the site.

The Three Volume Tiers

Washington’s litter control statute, RCW 70A.200.060, sorts dumping into three tiers by volume.¹

One cubic foot or less of non-dangerous material: Class 2 civil infraction. That is roughly a small kitchen trash bag. A 2024 change moved this smallest tier out of criminal court, so there is no criminal record attached.
More than one cubic foot but less than ten cubic yards: misdemeanor.
Ten cubic yards or more: gross misdemeanor.

Volume is not the only trigger. Discarding “potentially dangerous litter” in any amount, including broken glass, sharp metal scraps, or anything else that could injure someone, is automatically a Class 1 civil infraction, the most serious infraction class.¹

Fines and Jail Time

Civil infractions carry monetary penalties set by statute and no jail time. They do not create a criminal record, which was the point of the 2024 reform.¹

Criminal penalties climb sharply once you cross one cubic foot:

Misdemeanor dumping (more than one cubic foot, less than ten cubic yards): up to 90 days in county jail, up to a $1,000 fine, or both.²
Gross misdemeanor dumping (ten cubic yards or more): up to 364 days in county jail, up to a $5,000 fine, or both.²

Cleanup Restitution on Top of the Sentence

The fine is not the whole bill. Courts impose a separate cleanup restitution payment on top of any fine or jail sentence. For misdemeanor-level dumping, restitution equals four times the actual cost of cleanup. For gross misdemeanor dumping, it equals twice the actual cost. The portion matching the real cleanup expense goes to the landowner, and the rest goes to the law enforcement agency that investigated.¹

First-time offenders have some room to reduce the hit. A judge can suspend or reduce the restitution if you voluntarily clean up and properly dispose of the waste. The court can also order you to physically remove the material as an alternative to part or all of the restitution payment.¹

Dumping Solid Waste Without a Permit

A second statute, RCW 70A.205.195, targets disposing of solid waste at unpermitted locations, and its volume thresholds are tighter than the litter statute’s. Under this provision, anything over one cubic foot but less than one cubic yard is already a misdemeanor, not just anything over ten cubic yards.³

There is a narrow exception: you can dispose of waste from your own activities on land you own or lease, as long as doing so does not violate other laws or create a nuisance.³

Restitution under this statute works on a different formula. For misdemeanor-level violations, the payment is the greater of twice the actual cleanup cost or fifty dollars per cubic foot of waste. Half goes to the landowner and half to the local health department. If the landowner gave permission for the dumping or helped facilitate it, they get nothing, and the entire payment goes to the health department.³

Hazardous Waste Is a Different Track

The penalties above apply to ordinary trash, construction debris, appliances, and tires. Hazardous materials such as chemicals, asbestos, and medical waste sit under a completely different regulatory framework with far steeper consequences.

Washington’s Model Toxics Control Act, RCW 70A.305, directs the Department of Ecology to order responsible parties to clean up contaminated sites. If a responsible party refuses, Ecology can do the work and recover up to three times what it spent.⁴

Violating an Ecology enforcement order carries penalties of up to $25,000 per day, pursued in court by the state Attorney General.⁴ These are civil penalties rather than criminal, but they compound daily. A two-week standoff over a cleanup order could produce a penalty exceeding $350,000 before any cost recovery is added.

Federal Penalties That Can Stack

When hazardous waste is involved, federal criminal penalties under the Resource Conservation and Recovery Act can be layered on top of state consequences. RCRA gives the EPA authority over hazardous waste from generation through final disposal.⁵

Disposing of hazardous waste without a permit: up to five years in prison and fines of up to $50,000 per day, doubling for repeat violations.⁶
Transporting hazardous waste to an unpermitted facility: the same five-year maximum and $50,000 daily fine.⁶
Knowing endangerment, meaning dumping hazardous waste while knowing it puts someone in danger of death or serious injury: up to 15 years in prison and fines of up to $250,000 for individuals or $1,000,000 for organizations.⁶

Dumping into waterways can also trigger the Clean Water Act. Judicially-imposed civil penalties for unpermitted discharges into protected waters reach $68,446 per day per violation, and administrative penalties reach $27,379 per violation with a cap of $68,446.⁷

If Someone Dumped on Your Land

If you are the property owner and someone dumped on your land without your involvement, Washington law generally treats you as the victim. Both the litter statute and the solid waste statute direct cleanup restitution to the landowner, so the actual cleanup cost goes to you and the punitive portion goes to law enforcement or the local health department.

That protection vanishes if you gave permission or helped facilitate the dumping. Under RCW 70A.205.195, a landowner who authorized or assisted with illegal dumping loses all claim to restitution, and the full payment goes to the investigating health department.³

Hazardous contamination is separate. Under the Model Toxics Control Act, Ecology can pursue cleanup costs from “potentially liable persons,” which can include current property owners even if they did not cause the contamination.⁸ Reporting hazardous material found on your property to the Department of Ecology promptly is the safer course; ignoring it can weaken your position if liability questions come up later.

Legal Disposal Costs Less Than the Fine

The reason to know these numbers is that legal disposal is dramatically cheaper. Washington operates transfer stations and landfills in all 39 counties. In 2023, municipal solid waste tipping fees at Washington transfer stations ranged from under $50 per ton in some counties to over $300 per ton in island communities like San Juan County. Most facilities also charge per-load or per-cubic-yard rates for household cleanouts.

Household hazardous waste, including paint, solvents, batteries, pesticides, and used motor oil, needs separate handling. Congress exempted household hazardous waste from the strict federal tracking requirements that apply to commercial generators, but state and local rules still control where you can take it.⁹ Most counties run periodic collection events or permanent drop-off sites at no charge or reduced cost.

Compare the math directly. Even the highest transfer station fee in Washington costs far less than a criminal fine plus cleanup restitution set at two to four times the actual cleanup cost. For businesses, skipping the federal manifest system or using an unpermitted disposal site to save on tipping fees exposes you to RCRA penalties starting at $50,000 per day.
