Understanding Criminal Investigations

EPA Special Agents investigate the most significant and egregious violations of environmental laws which pose significant threats to human health and the environment.  Your Safety Comes First - never try and investigate on your own - report what you see at www.epa.gov/tips.  Criminal investigations may be prompted by reports from victims or concerned citizens, or from violations which cause significant harm. 

Frequently, the investigations of environmental crimes will uncover other types of crimes, such as lying to the government, fraud or conspiracy. These crimes could also be prosecuted.  Some environmental concerns are handled by State and Local Authorities who have immediate jurisdiction over such matters. Click the "Recognizing Violations" tabs below for more information.

What is an Environmental Crime?

Generally speaking, an environmental crime is a negligent, knowing or willful violation of a federal environmental law. "Knowing" violations are those that are deliberate and not the product of an accident or mistake.
