risk assessments; a description of food chain models useful in risk assessment; summaries of

the toxicology of likely contaminants of concern at dredged material management sites; and

an approach to weight of evidence.

The USACE ERED database. USACE has an on-line Environmental Residue-Effects Data-

base (ERED), which summarizes by organism and chemical some toxicological effects

associated with specific levels of contaminants in tissue. This database is operating and

accessible on-line through the U.S. Army Engineer Waterways Experiment Station, Dredging

Operations Technical Support (DOTS) home page (http://www.wes.army.mil/el/dots).

Ecological and Human Health Risk Assessment Guidance for Upland Sites. This document

will be similar to the guidance for aquatic sites, but will address risk assessment at upland

management sites.

Guidance for Assessing "Non-Contaminant" Impacts at Dredged Material Management

Sites. This document will provide guidance for applying risk assessment methods at sites

where the sources of impact are physical disturbances. These may include suspended

sediments, habitat alteration, or operational interference with critical life stages or functions

requiring the development of "environmental windows" into the operational schedule.

Guidance for Incorporating Quantitative Uncertainty and Probabilistic Analyses into Risk

Assessment at Dredged Material Management Sites. This document will provide guidance

for incorporating probabilistic assessment into the estimates of risk characterization.

Guidance for Comparative Risk Assessment. Comparative risk assessment is of particular

importance to risk management when attempting to distinguish among several sites or several

management technologies at a site. This document will describe methods for comparing

ecological and human health risks among management alternatives.
