The overall objective of this manual is to provide risk assessors with
the recommended basic/minimum requirements for developing scopes of
work, evaluating Architect-Engineer (A-E) prepared human health risk
assessments, and documenting risk management options associated with
Hazardous, Toxic, and Radioactive Waste (HTRW) investigations, studies,
and designs consistent with principles of good science in defining the
quality of risk assessments. This EM is intended for use by U.S. Army
Corps of Engineers (USACE) Project Managers, technical personnel, and
