Section 404 Enforcement

In addition to jointly implementing the Clean Water Act Section 404 program, EPA and the U.S. Army Corps of Engineers (Corps) share Section 404 enforcement authority. This webpage gives an overview of how the agencies implement this shared authority.

Types of Violations

Section 404 violations fall into two broad categories:

In 1989, EPA and the Corps entered into a Memorandum of Agreement (MOA) on enforcement to ensure efficient and effective implementation of this shared authority. Under the MOA, the Corps, as the Federal agency that issues permits, has the lead on Corp-issued permit violation cases. For unpermitted discharges, EPA and the Corps determine the appropriate lead agency based on criteria in the MOA.

Enforcement Goals and Tools

EPA's Section 404 enforcement program has three goals: protect the environment and human health and safety, deter violations, and treat the regulated community fairly and equitably. EPA's enforcement program achieves these goals through voluntary compliance and by using the enforcement tools provided under Sections 309 and 404 of the Clean Water Act.

In administrative enforcement, under Section 309(a), EPA can issue administrative compliance orders requiring a violator to stop any ongoing illegal discharge activity and, where appropriate, to remove the illegal discharge and otherwise restore the site. Under Section 309(g), EPA can assess administrative civil penalties of up to $16,000 per day of violation, with a maximum cap of $177,500 in any single enforcement action.

In judicial enforcement, Sections 309(b) and (d) and 404(s) give EPA and the Corps the authority to take civil judicial enforcement actions, seeking restoration and other types of injunctive relief, as well as civil penalties. The agencies also have authority under Section 309(c) to bring criminal judicial enforcement actions for knowingly or negligently violating Section 404.

Case Selection

EPA and the Corps consider a wide variety of factors when deciding whether to initiate an enforcement action and, if so, what type of action to pursue. These factors include the amount of fill, the size of the water body (acres of wetlands filled and the environmental significance), the discharger's previous experience with Section 404 requirements, and the discharger's compliance history.

In most instances, EPA and the Corps prefer to resolve Section 404 violations through voluntary compliance or administrative enforcement.

Section 404 Criminal Enforcement

Since enactment of the Clean Water Act, EPA and the Corps have used their criminal enforcement authorities sparingly in response to Section 404 violations. As demonstrated by the following example, EPA and the Corps reserve their criminal enforcement authority for only the most flagrant and egregious Section 404 violations.

United States v. Lucas

On February 25, 2005 in the Southern District of Mississippi, a jury convicted Robert J. Lucas, Jr., his daughter, Robbie Lucas Wrigley, and his engineer, M.E. Thompson, Jr., on all 41 counts of an indictment which charged violations of Sections 402 and 404 of the Clean Water Act, mail fraud and conspiracy. The charges resulted from the development and sale by Lucas of hundreds of lots in the Big Hill Acres subdivision that impacted approximately 260 acres of wetlands without Corps of Engineers permits. In developing the lots, Lucas filled wetlands for the construction of driveways and septic systems. The construction persisted after Lucas was ordered to desist by EPA and other agencies. Wrigley sold lots and otherwise participated in the conspiracy knowing that the lots were saturated and could not support septic systems.  M.E. Thompson, a professional engineer, wrongfully certified that the lots were suitable for septic systems, even after being told by the local health department to the contrary.  In December 2005, the District Court sentenced Lucas to 108 months in prison and Wrigley and M.E. Thompson, Jr. to 87 months apiece.  The court fined each of the Defendants $15,000, assessed restitution of $1,407,400 for each Defendant and fined Lucas’s two companies Big Hill Acres, Inc., $4,800,000 and Consolidated Investments, Inc., $500,000. The case represents the most significant criminal wetlands case in the history of the Clean Water Act.

The Decision was affirmed on appeal by the U.S. Court of Appeal for the Fifth Circuit on February 1, 2008, and later denied certiorari by the U.S. Supreme Court.
