Risk Assessment

ECO Update Bulletin Series

ECO Update is a bulletin series on ecological risk assessment of Superfund sites. These bulletins serve as supplements to Risk Assessment Guidance for Superfund, Volume II: Environmental Evaluation Manual (EPA/540-1-89/001). The information presented is intended to provide technical information to EPA and other government employees. It does not constitute rulemaking by the Agency, and may not be relied on to create a substantive or procedural right enforceable by any other person. The Government may take action that is at variance with these bulletins.

Disclaimer: These electronic files are courtesy copies of the ECO Update bulletin series and have been reformatted to make them available to you in electronic form. Formatting (margins, page numbering, etc.) may be different from the original hard copies to make the documents more easily readable on your computer screen. If any discrepancies with the original hard copies are found, the original hard copies are the official bulletins.
