Rule of Law:
For felony violations of the Clean Water Act under 33 U.S.C. § 1319(c)(2), the government need only prove the defendant knowingly engaged in the conduct that resulted in the permit violation, not that the defendant knew their conduct was illegal or violated the permit.
Facts:
- Michael H. Weitzenhoff and Thomas W. Mariani were the manager and assistant manager, respectively, of the East Honolulu Community Services Sewage Treatment Plant.
- The plant operated under a National Pollution Discharge Elimination System (NPDES) permit, which set limits on pollutants it could discharge into the ocean near Sandy Beach, Oahu.
- In March 1988, after plant improvements, the practice of hauling away excess waste activated sludge (WAS) was discontinued.
- Shortly thereafter, the plant experienced a buildup of excess WAS.
- Instead of resuming the hauling of the excess WAS, Weitzenhoff and Mariani instructed employees to dispose of it by pumping it directly into the ocean outfall.
- These discharges of WAS occurred on approximately 40 separate occasions between April 1988 and June 1989.
- The method of discharge bypassed the plant's official effluent sampler, meaning the discharges were not reflected in mandatory monitoring reports sent to regulators.
- When contacted by health officials about complaints, Weitzenhoff and Mariani denied any problems at the plant, and one employee was told not to say anything about the discharges.
Procedural Posture:
- The United States charged Michael H. Weitzenhoff and Thomas W. Mariani in a thirty-one-count indictment in the U.S. District Court for the District of Hawaii for violations of the Clean Water Act.
- Before trial, the district court construed the statute's 'knowingly' requirement as only mandating proof that the defendants were aware of their actions of discharging pollutants, not that they knew their actions were unlawful.
- The district court rejected the defendants' proposed jury instruction that a mistaken belief about the permit's authorization would be a valid defense.
- A jury convicted Weitzenhoff and Mariani on six of the thirty-one counts.
- The district court sentenced Weitzenhoff to twenty-one months and Mariani to thirty-three months imprisonment.
- Weitzenhoff and Mariani (appellants) appealed their convictions to the United States Court of Appeals for the Ninth Circuit.

Issue:
Does a felony conviction under the Clean Water Act for 'knowingly violat[ing] ... any permit condition' require the government to prove that the defendant knew their conduct was illegal or violated the specific terms of the permit?
Opinions:
Majority - Fletcher, J.
No. A felony conviction under the Clean Water Act (CWA) for a knowing violation does not require proof that the defendant knew their conduct was illegal or violated a permit; it only requires proof that the defendant knowingly engaged in the conduct that resulted in the violation. The CWA is a public welfare statute designed to protect the public from the dire consequences of water pollution. Citing United States v. International Minerals, the court reasoned that where 'dangerous or deleterious devices or products or obnoxious waste materials are involved, the probability of regulation is so great that anyone who is aware that he is in possession of them or dealing with them must be presumed to be aware of the regulation.' The term 'knowingly' in the statute refers to the defendant's knowledge of their actions (e.g., opening a valve to discharge waste), not their knowledge of the law. This interpretation is supported by legislative history and is not undermined by recent Supreme Court cases like Staples v. United States, which explicitly distinguished gun laws from regulations governing 'obnoxious waste materials,' thereby reaffirming the public welfare offense doctrine in the environmental context. Therefore, the government was not required to prove Weitzenhoff and Mariani knew their acts violated the permit or the CWA.
Dissenting - Kleinfeld, J.
Yes. A felony conviction for 'knowingly violat[ing] ... any permit condition' should require proof that the defendant knew they were violating the permit. The plain language and grammar of the statute—where the adverb 'knowingly' modifies the verb 'violates'—compels this conclusion. The majority's interpretation reads the statute as criminalizing 'knowingly discharging pollutants,' which is not what Congress wrote, and effectively eliminates the mental state required to distinguish an innocent mistake from a felony. This approach risks making felons out of morally innocent people doing socially valuable work who may unknowingly violate a complex permit. If the statute is ambiguous, the rule of lenity demands it be interpreted in favor of the defendant. Furthermore, the Supreme Court's decisions in Staples and Ratzlaf emphasize that a higher level of mens rea is presumed for felony offenses, particularly for 'public welfare' or malum prohibitum crimes where the conduct is not inherently evil. The majority's decision ignores this precedent and creates a massive, unjustified legal risk for essential public servants.
Analysis:
This decision solidifies the application of the 'public welfare offense' doctrine to environmental statutes, significantly lowering the government's burden of proof for felony convictions under the Clean Water Act. By holding that 'knowingly' refers only to the act itself and not to knowledge of its illegality, the case makes it easier to convict corporate officers and managers who authorize polluting activities, regardless of their claimed ignorance of the law or specific permit conditions. This precedent has a broad impact on environmental criminal enforcement, placing a heavy burden on individuals in regulated industries to know and comply with the law at their peril. The strong dissent, however, highlights the ongoing tension in criminal law between using strict liability to enforce public welfare regulations and the traditional principle that felony punishment should be reserved for those with a morally culpable state of mind.
