1. What Evidence Can Prompt a Criminal Referral?
A mismatch between laboratory results and submitted reports can raise questions about who changed the figures and why. Inspectors may also identify bypass equipment, unauthorized waste disposal, or repeated violations after warnings. These facts can support further investigation, but a reporting discrepancy alone does not establish criminal intent.
Records Can Distinguish an Error from Concealment
Investigators compare original sample results, maintenance logs, emails, and reporting histories to reconstruct what employees knew and did. A documented correction differs from deleting test results before an inspection.
A Civil Inspection Is Not a Required First Step
EPA’s Criminal Investigation Division (CID) may investigate suspected crimes without an earlier civil inspection. Civil and criminal teams can also pursue related conduct through parallel proceedings. A continuing compliance review does not establish that criminal exposure has ended.
2. The Offense Determines the Required Intent and Penalty
Federal environmental laws do not impose one uniform criminal standard. Some provisions punish knowing conduct, while others cover negligent violations. For a conviction, prosecutors must prove the charged offense beyond a reasonable doubt. The distinction between negligence, knowledge, and knowing endangerment affects both the evidence required and the available sentence.
Water, Air, and Hazardous Waste Charges Differ
Under 33 U.S.C. § 1319(c), a first Clean Water Act conviction can carry up to one year for specified negligent violations. Specified knowing violations carry up to three years, while knowing endangerment carries up to 15 years. Clean Air Act § 7413(c)(1) permits up to five years for specified knowing violations. Under RCRA § 6928(d)(2)(A), knowingly treating, storing, or disposing of hazardous waste without a required permit carries up to five years.
False Reports Have Separate Criminal Provisions
The Clean Water Act and Clean Air Act contain reporting and monitoring offenses with two-year maximum terms for first convictions under specified provisions. A materially false statement within federal jurisdiction may also implicate 18 U.S.C. § 1001, depending on its elements. A Federal Criminal Defense review must identify the actual charge rather than apply the highest penalty across the entire investigation.
3. How Should a Facility Respond to a Search or Subpoena?
When agents execute a search warrant, request the warrant, identify the lead agent, and contact counsel promptly. Do not obstruct the search or alter records. Review the authorized premises and items, and document what agents take without interfering. The property receipt and inventory concern items seized; they are distinct from the warrant’s description of what agents may search for.
Preserve Records and Review Production Obligations
Suspend routine deletion of relevant emails, laboratory data, and backups, and retain original versions of disputed reports. A subpoena requires a separate review of its deadline, scope, and privilege issues. Counsel handling Grand Jury Investigations can assess objections and production obligations.
Employee Interviews Can Create Separate Legal Risks
An employee approached for a voluntary interview may decline and seek legal advice before answering. Miranda warnings generally concern custodial interrogation, so their absence does not make workplace statements unusable. Knowingly making a materially false statement can create separate exposure even when agents have not placed the speaker under arrest.
Company Counsel May Not Represent Each Employee
The Fifth Amendment protects individuals against compelled self-incrimination, but it does not give corporations a comparable privilege over corporate records. Employees should clarify whom company counsel represents before discussing personal exposure. A White Collar Criminal Defense review can address conflicts between the company and its personnel. Management should not coach answers or pressure witnesses to conceal information.
4. Frequently Asked Questions about EPA Criminal Investigations
Will I Receive a Target Letter Before EPA Investigates Me?
Not necessarily. A target letter is not a prerequisite for opening an EPA criminal investigation. DOJ policy encourages prosecutors to notify targets before seeking an indictment in appropriate cases, but it recognizes exceptions when notice could jeopardize the investigation. The absence of a letter therefore does not establish that you are only a witness or that charges are unlikely.
Can Voluntarily Reporting a Violation Prevent Criminal Prosecution?
Voluntary disclosure does not automatically prevent prosecution. EPA’s Audit Policy provides conditional incentives for entities that discover, disclose, and correct qualifying violations, including no recommendation for criminal prosecution when applicable conditions are satisfied. Eligibility depends on factors such as voluntary discovery, prompt disclosure, and discovery independent of government action. Reporting a problem after inspectors identify it does not necessarily qualify, and an EPA recommendation is not a grant of immunity.
