Improving Corps Civil Works Compensatory Mitigation Act

This bill (S 4157) updates the process for compensatory mitigation - replacing or restoring damaged wetlands and waterways - when federal civil works projects cause environmental harm. It requires the U.S. Army Corps of Engineers to use specific "contracts" with mitigation providers that follow established Corps practices and prioritize existing state or local restoration plans for the affected area. The bill also mandates that these contracts comply with the 2008 federal rule on compensatory mitigation for aquatic resources. This change directly affects the Corps, mitigation providers, and project sponsors involved in civil works projects needing environmental mitigation.
