Criminal Culpability Requirements.
Under the Washington State Criminal Code (Criminal Code), there are four general categories of mental states required for a person to be found guilty of committing a crime: intent, knowledge, recklessness, and criminal negligence.
Intentional. A person acts with intent or intentionally when the person acts with the objective or purpose to accomplish a result which constitutes a crime.
Knowingly. A person acts knowingly or with knowledge when the person is aware of a fact, facts, or circumstances or result described by a statute defining an offense, or the person has information which would lead a reasonable person in the same situation to believe that facts exist which are described by a statute defining an offense. A requirement that an offense be committed willfully is satisfied if a person acts knowingly with respect to the material elements of the offense, unless there is a clear purpose to impose further requirements.
Reckless. A person is reckless or acts recklessly when the person knows of and disregards a substantial risk that a wrongful act may occur and the person's disregard of such substantial risk is a gross deviation from conduct that a reasonable person would exercise in the same situation.
Criminally negligent. A person is criminally negligent or acts with criminal negligence when the person fails to be aware of a substantial risk that a wrongful act may occur and the person's failure to be aware of such substantial risk constitutes a gross deviation from the standard of care that a reasonable person would exercise in the same situation.
Entity Liability.
Under the Criminal Code, a corporation is guilty of an offense when the conduct constituting the offense:
An individual is criminally liable for conduct constituting an offense that the individual performs or causes to be performed in the name of or on behalf of a corporation to the same extent as if such conduct were performed in the individual's own name or on the individual's behalf.
Whenever a duty to act is legally imposed upon a corporation, any agent who knowingly shares primary responsibility for the duty is criminally liable for a reckless, or if a high managerial agent, a criminally negligent omission to perform the required act to the same extent as if the duty were imposed directly upon the agent. Every corporation convicted of criminal conspiracy to commit any offense forfeits the right to do business in Washington.
Crimes are classified as misdemeanors, gross misdemeanors, or felonies. The classification of a crime generally determines the maximum term of confinement or fine imposed, or both, for an offense. For each classification, the maximum terms of confinement and maximum fines are as follows:
| Classification | Maximum Confinement | Maximum Fine |
| Misdemeanor | 90 days | $1,000 |
| Gross Misdemeanor | 364 days | $5,000 |
| Class C Felony | 5 years | $10,000 |
| Class B Felony | 10 years | $20,000 |
| Class A Felony | Life | $50,000 |
When a person is convicted of a felony, the Sentencing Reform Act (SRA) applies and determines a sentence range within the statutory maximum. Sentence ranges are determined by reference to a sentencing grid that provides a standard range of months for the sentence based on both the severity, or "seriousness level," of the offense and the convicted person's "offender score," which is based on the offender's criminal history. Seriousness levels range from I to XVI. Offender scores can range from zero to nine or more points. A higher seriousness level or offender score results in a longer sentence. If an offense does not have a designated serious level, also referred to as an unranked offense, then the maximum sentence is one year.
For entities, unless a special fine is specified for an offense, the maximum fines are as follows:
| Classification | Maximum Fine |
| Misdemeanor | $50,000 |
| Gross Misdemeanor | $250,000 |
| Class C Felony | $500,000 |
| Class B Felony | $750,000 |
| Class A Felony | $1,000,000 |
Water Pollution Control Act.
The Water Pollution Control Act (WPCA) grants the Department of Ecology (Ecology) authority to control and prevent the pollution of certain waters of Washington, including lakes, rivers, ponds, streams, salt waters, and other waters within the state. Under this authority, Ecology establishes water quality standards for regulated waters and issues permits relating to the discharge of pollutants into such waters.
Penalties.
The WPCA contains both civil and criminal penalties. A person found guilty of willfully violating any provisions of the WPCA or the Oil and Hazardous Substance Spill Prevention and Response Act, or any final written orders or directive of Ecology or a court is guilty of a gross misdemeanor. If convicted, the person may be punished by a fine of up to $10,000, imprisonment for up to 364 days, or both. Each day of a willful violation may be deemed as a separate and additional violation.
Clean Air Act.
The state Clean Air Act (CAA) grants Ecology, clean air agencies, and tribal governments authority to regulate outdoor air pollution in Washington. Under this authority, the relevant regulating entity issues air quality permits, sets emission standards for certain sources of air pollution, declares air pollution episodes, and requires greenhouse gas reporting.
Penalties.
The CAA contains both civil and criminal penalties. A person who knowingly violates any provisions of the CAA or other specified statutes relating to motor vehicle emission control; hydrofluorocarbons; the Clean Fuels Program; or any ordinance, resolution, or regulations implementing those provisions is guilty of a gross misdemeanor. If convicted, the person may be punished by a fine of up to $10,000, imprisonment for up to 364 days, or both.
A person who knowingly releases into the ambient air any substance listed by Ecology as a hazardous air pollutant, other than in compliance with an applicable permit or emission limit, and who at the time knowingly places another person in imminent danger of death or substantial bodily harm is guilty of a Class C Felony. If convicted, the person may be punished by a fine of up to $50,000, imprisonment for up to 5 years, or both.
A person who negligently commits the offense is guilty of a gross misdemeanor, which is punishable by a fine of up to $10,000, imprisonment for up to 364 days, or both. A separate gross misdemeanor offense exists for certain clean air agency members failing to disclose a conflict of interest.
Hazardous Waste Management Act.
The Hazardous Waste Management Act (HWMA) grants Ecology authority to regulate the management of hazardous wastes and releases of hazardous substances. Under this authority, Ecology adopts regulations relating to properly designating and managing certain dangerous or hazardous wastes.
Penalties.
The HWMA contains both civil and criminal penalties. A Class B Felony under this section is punishable by up to a $20,000 fine, ten years of imprisonment, or both. A Class C Felony is punishable by up to a $10,000 fine, five years of imprisonment, or both.
A person who knowingly transports, treats, stores, handles, disposes of, or exports a hazardous substance in violation of the HWMA is guilty of a:
Imminent danger means there is a substantial likelihood that harm will be experienced within a reasonable period of time should the danger not be eliminated. Knowingly refers to an awareness of facts, not an awareness of the law.
A person who violates any provisions of the HWMA or any implementing rules, and a person who knowingly aids or abets another in conducting any such violation is guilty of a gross misdemeanor. If convicted, the person must be punished by a $100 to $10,000 fine, imprisonment for up to 364 days, or both, for each separate violation. Each violation is a separate and distinct offense.
Water Pollution Control Act Violations.
An entity is guilty of an offense committed by an agent of the entity if the agent commits the offense while acting within the scope of the agent's duties and on behalf of the entity. Each day that a violation occurs may be deemed a separate and additional violation. The WPCA violations do not apply to silt and sediment discharges permitted by a construction stormwater general permit.
First-Degree Violation. A person is guilty of a WPCA violation in the first degree if the person knowingly violates any provisions of the WPCA, the Oil and Hazardous Substance Prevention and Response Act, or any permit issued under the WPCA or the federal Clean Water Act, and the person knows at the time that the conduct constituting the violation places another person in imminent danger of death or serious bodily harm. A first-degree violation is punishable as a Class B Felony.
Second-Degree Violation. A person is guilty of a WPCA violation in the second degree if the person, under circumstances not amounting to a first-degree violation, knowingly violates any provisions of the WPCA, the Oil and Hazardous Substance Prevention and Response Act, any final written orders or directive of Ecology or a court, or any permit issued under the WPCA or the federal Clean Water Act. A second-degree violation is punishable as a Class C Felony.
Third-Degree Violation. A person is guilty of a WPCA violation in the third degree if the person, under circumstances not amounting to a first-degree or second-degree violation, negligently violates any provisions of the WPCA, the Oil and Hazardous Substance Prevention and Response Act, or any final written orders or directive of Ecology or a court, any permit issued under the WPCA or the federal Clean Water Act. A third-degree violation is a gross misdemeanor punishable by a fine of up to $10,000 and costs of prosecution, by imprisonment for up to 364 days, or both, at the discretion of the court.
Clean Air Act Violations.
An entity is guilty of an offense if an agent of the entity commits the offense while acting within the scope of the agent's duties and on behalf of the entity. Each day that a violation occurs may be deemed a separate and additional violation. For the purposes of the CAA violations, air pollutant does not include an odorous substance unless it is listed by Ecology as hazardous or toxic. Certain activities relating to outdoor burning permitted by the Department of Natural Resources, or permitted or conducted by a state or local authority, and odors or fugitive dust caused by agricultural activity consistent with good agricultural practices, are exempted from the CAA violations.
First-Degree Violation. A person is guilty of a CAA violation in the first degree if the person knowingly releases into the ambient air any substance listed by Ecology as a hazardous or toxic air pollutant, other than in compliance with the terms of an applicable permit or emission limit, and the person knows at the time that the person thereby places:
A first-degree violation is punishable as a Class B Felony.
Second-Degree Violation. A person is guilty of a CAA violation in the second degree if the person, under circumstances not amounting to a first-degree violation:
A second-degree violation of the CAA is punishable as a Class C Felony.
Third-Degree Violation. A person is guilty of a CAA violation in the third degree if the person, under circumstances not amounting to a first-degree or second-degree violation:
A third-degree violation is a gross misdemeanor, punishable by a fine of up to $10,000 and costs of prosecution, by imprisonment for up to 364 days, or both.
Hazardous Waste Management Violations.
An entity is guilty of an offense if an agent of the entity commits the offense while acting within the scope of the agent's duties and on behalf of the entity. Each day that a violation occurs may be deemed a separate and additional violation.
First-Degree Violation. A person is guilty of a HWMA violation in the first degree if the person knowingly transports, treats, stores, handles, disposes of, or exports a hazardous substance in violation of the HWMA and the person knows at the time that the conduct constituting the violation:
A first-degree violation is punishable as a Class B Felony.
Second-Degree Violation. A person is guilty of a HWMA violation in the second degree if the person, under circumstances not amounting to a first-degree violation, knowingly violates any provisions of the HWMA or the implementing rules. A second-degree violation of the HWMA is punishable as a Class C Felony.
Third-Degree Violation. A person is guilty of a HWMA violation in the third degree if the person, under circumstances not amounting to a first-degree or second-degree violation, negligently violates any provisions of the HWMA or the implementing rules.
