scope:

Purpose. This document is intended to serve as a guide to project team members for the use of statistics in environmental decision-making. The foundation of Corps of Engineers environmental work is the Environmental Operating Principles as specified in ER 200-1-5. These seven tenets serve as guides and must be applied in all Corps business lines as we strive to achieve a sustainable environment.

Applicability. The U.S. Army Corps of Engineers (USACE) developed this document within the broader scope of Technical Project Planning (TPP), recognizing that understanding statistical evaluations can improve project planning and implementation at hazardous, toxic, and radioactive waste (HTRW) sites.
