Illegal Dumping Charges - California Penal Code 374.3

Posted by Bulldog Law | Jun 23, 2025

Illegal Dumping Charges

If you've been charged with illegal dumping under California Penal Code Section 374.3, you're likely anxious about what comes next. This law addresses the unlawful disposal of waste on public or private property, and a conviction can lead to steep financial penalties, loss of your vehicle, and even professional consequences. However, being charged does not mean you are without defense. With experienced legal guidance, many individuals successfully challenge or mitigate these accusations.

What Does California Penal Code Section 374.3 Prohibit?

Penal Code 374.3 makes it unlawful to throw, dump, or leave waste material in any place not officially designated for waste disposal—this includes both public areas and private land without the owner's consent. Offenses under this code can range from infractions to misdemeanors, depending on the severity and circumstances.

To secure a conviction, the prosecution must prove:

  • You knowingly disposed of waste;
  • The site was unauthorized for waste disposal;
  • You lacked the property owner's permission.

Each element creates an opportunity for a skilled attorney to challenge the charge and potentially get it reduced or dismissed.

Beyond the Fine: Understanding the Financial Impact

Violating PC 374.3 often results in more than just a simple fine. Under Penal Code Section 1202.51, the court must impose mandatory fines—$100 for infractions and $200 for misdemeanors—on top of any other penalties. While these fines are legally required, the court may reduce them based on your ability to pay, which is where an attorney can advocate on your behalf.

Additionally, Penal Code Section 1463.9 allocates 50% of collected fines to local cleanup efforts. This creates a financial incentive for courts to enforce penalties, making strong defense representation critical if you want to avoid unnecessary hardship.

The Risk of Vehicle Impoundment

One lesser-known but serious consequence is vehicle impoundment. If you have a prior conviction under Section 374.3 and are caught dumping waste while operating a vehicle, Vehicle Code Section 23112.7 allows the court to impound that vehicle for up to six months.

The decision to impound hinges on factors like:

  • The amount and type of dumped material;
  • Whether the act was commercial in nature;
  • Any history of similar violations.

For business owners especially, this can lead to severe disruption. Legal support is vital to challenge or avoid vehicle seizure.

Impact on Professional Licenses

For professionals such as contractors, waste haulers, or anyone with an environmental compliance license, an illegal dumping conviction can affect your livelihood. Under Business and Professions Code Section 7110, licensing boards may take disciplinary action, including suspension or revocation of your license.

If you're licensed in California and charged under PC 374.3, prompt action is essential. A defense lawyer who understands both criminal and licensing implications can help preserve your career.

Legal Defenses Against Illegal Dumping Charges

There are multiple strategies to fight an illegal dumping accusation:

  • Lack of Knowledge: If you were unaware that a location was not authorized for waste disposal, your intent can be challenged.
  • Property Owner Consent: If you had permission to use the property, even if informal, it can invalidate the charge.
  • Mistaken Identity: In cases based on surveillance footage or eyewitness reports, misidentification is a common issue—especially at night or with similar-looking vehicles.
  • Necessity or Emergency: Rare, but possible. If you disposed of hazardous waste to prevent greater harm, necessity could be a valid defense.

Additionally, some defendants are wrongfully accused of violating California Penal Code 602 trespassing laws, even though the underlying issue was improper waste disposal. In such situations, an attorney may pursue dismissal or reduction based on improper charging.

The Role of Informants and the 374a Reward System

Many people are surprised to learn that Penal Code Section 374a creates a reward program where informants can receive up to 50% of the fines collected from a successful conviction. This financial incentive may compromise the objectivity of witnesses.

A good defense attorney will examine these motivations and cross-examine informants thoroughly. Their bias could be the key to weakening the prosecution's case.

Investigating the Scene and Evidence

Defending an illegal dumping charge starts with examining all relevant details:

  • Was the dumped material correctly identified and tested?
  • Was the chain of custody properly maintained?
  • Is the location clearly unauthorized under local law?

Often, what appears to be an illegal site may be more ambiguous under municipal or county regulations. Reviewing local zoning codes and ownership records is essential to building a strong defense.

If the charges arise during or near a protest or other event, the situation might also involve allegations under California Penal Code 415 disturbing the peace. When that occurs, separating the dumping charge from unrelated allegations becomes a key part of your legal strategy.

Negotiating with Prosecutors

Not every case needs to go to trial. Especially for first-time offenders or those accused of minor infractions, prosecutors may be open to resolving the matter through:

  • Community service;
  • Environmental education programs;
  • Restitution in lieu of fines.

An experienced attorney can work with the District Attorney's office to seek a resolution that avoids a criminal conviction and protects your future.

Long-Term Consequences You Must Consider

A conviction for illegal dumping does not just disappear. It becomes part of your criminal record and can show up on background checks for jobs, housing, or loans. If you are a non-citizen, it could also create immigration problems.

For these reasons, it's important to treat a PC 374.3 charge as seriously as you would any criminal matter. Working with a defense lawyer right away maximizes your chances of protecting your rights and your record.

Why Acting Fast Matters

Illegal dumping laws intersect with numerous other California statutes. Between the mandatory financial penalties, the risk of impoundment, the effect on licenses, and biased witnesses hoping for a cash reward, the sooner you begin building your case, the better your options will be.

Being proactive by hiring a criminal defense attorney can help you avoid outcomes that might otherwise seem inevitable.
