“NEPA Success Stories …” is a compilation of articles featured in DOE’s NEPA Lessons Learned Quarterly Report from 1996 through 2016. Some of the articles in this collection describe how the NEPA process provided an organized structure for making some of the Department’s most complex decisions. Some articles feature NEPA reviews that resulted in significant project cost savings through informed decisionmaking. Some articles highlight ways in which the NEPA process improved environmental outcomes, such as by identifying better alternatives or more effective mitigation. Still other articles put the spotlight on procedural success, such as effective public involvement, enhanced tribal consultation, and efficient analysis.
