Advanced NEPA Topics: Blending Compliance Laws and Cumulative Impact Analysis


This four-day course consists of an in-depth examination of two topics related to conducting the National Environmental Policy Act (NEPA) process: cumulative impact analysis and integration of other environmental laws into NEPA.

Through the course, participants will gain an increased understanding of the legal requirements for cumulative impact analysis and will explore methods for identifying cumulative actions, framing analysis and describing cumulative impacts. Participants will also gain an increased understanding of other environmental mandates such as the National Historic Preservation Act and the Endangered Species Act and will investigate how to best integrate their requirements into the NEPA process.
