Strategic Considerations for Environmental Practice

Early Settlement Benefits

Environmental enforcement actions often benefit from early settlement discussions. EPA's penalty policy provides significant reductions for voluntary disclosure, cooperation, and rapid compliance.

Permit Strategy

Environmental permits often have complex procedural requirements and tight deadlines. Consider whether to pursue administrative appeals or proceed directly to federal court challenges.

Citizen Suit Considerations

Many environmental statutes authorize citizen suits for ongoing violations. The 60-day notice requirement provides an opportunity for settlement before litigation costs escalate.

Multi-Media Compliance

Environmental matters often involve multiple media (air, water, waste) and overlapping jurisdiction. Coordinate compliance strategies across all applicable environmental programs.
