Enforcing environmental laws is a central part of EPA's Strategic Plan to protect human health and the environment. EPA works to ensure compliance with environmental requirements. When warranted, EPA will take civil or criminal enforcement action against violators of environmental laws. Learn more about our enforcement goals.
One of EPA's top priorities is to protect communities disproportionately affected by pollution through our environmental justice (EJ) work. EPA is integrating EJ into areas such as:
This section provides basic information on EPA’s enforcement and compliance programs, actions, activities, reports and data.
Many of the nation’s environmental statutes contain both civil and criminal revisions to address pollution violations.
As a result of this distinction, most of the environmental crimes that EPA investigates involve "knowing violations" of the law. These are classified as felonies in all the federal environmental statutes except for the toxic substances and pesticide statutes.
In a "knowing violation" the person or company is aware of the facts that create the violation. A conscious and informed action brought about the violation. In contrast, a civil violation may be caused by an accident or mistake.
Examples of “knowing violations” include an intentional decision to dispose or dump pollutants into a river without a permit, or to not install a required air pollution control device.
To be found civilly liable for violating environmental laws the standard of proof is based upon "the preponderance of the evidence." This means that the evidence presented is convincing and more likely to be true than not true. Effectively, the standard is satisfied if there is a greater than 50 percent chance that the evidence is true.
The defendant in a civil suit can either be found liable, following a trial, or reach a mutually agreed-upon settlement with the government. The defendant is then required to meet all of the terms of the settlement, but does not have to acknowledge that he violated the law.
Criminal guilt must be established "beyond a reasonable doubt." This is a higher or stricter standard than the civil liability standard. When a criminal defendant pleads guilty or is convicted by a jury, there is no question of legal wrongdoing. He has legally committed the crime.
In criminal prosecutions, a person can be sentenced to prison. It is the possibility of imprisonment that most distinguishes criminal law from civil law.
If a civil defendant is found liable or agrees to a settlement, the result can be:
If a criminal defendant is convicted or pleads guilty, the result can be:
Cleanup enforcement gets property cleaned up by:
Federal facilities enforcement ensures federal facilities comply with environmental regulations and statutes.
Civil Administrative Actions are non-judicial enforcement actions taken by EPA or a state under its own authority. These actions do not involve a judicial court process. An administrative action by EPA or a state agency may be in the form of:
Civil Judicial Actions are formal lawsuits. They are filed in court, against persons or entities that have failed to:
These cases are filed by the U.S. Department of Justice on behalf of EPA. In civil cases they are typically filed by the State's Attorneys General on behalf of the states. Learn more about Civil Cases and Settlement.
Criminal Actions can occur when EPA or a state enforce against a company or person through a criminal action. Criminal actions are usually reserved for the most serious violations, those that are willful, or knowingly committed. A court conviction can result in fines or imprisonment.
