Consideration of Options
be difficult, not only for the designated decision-makers but also for the other affected parties who will have to implement and live with the decision. Affected parties might assume that the availability of a wealth of site-specific data, well-conducted human health and ecological risk assessments, and a thorough review of the risks associated with potential risk-management options will automatically lead to a determination of the most-effective and acceptable risk-management strategy. However, that assumption is often not the case, because decision-makers are dealing with a multivariate system, which involves a diverse community with differing expectations, interests, risk tolerance, and willingness to pay. This complexity has been a major contributor to the slow progress on risk management at many PCB-contaminated-sediment sites to date. New procedures are needed to accommodate the multivariate complexity at contaminated sites.
In this chapter, the committee summarizes the regulatory environment in which any decision-making process on a PCB-contaminated site must take place, reviews the various components of the decision-making process, discusses how these processes relate to the risk-management framework described in this report, and shows how the process may be facilitated.
The need to comply with various federal and state regulations when managing a PCB-contaminated-sediment site cannot be ignored. The regulations involved in the risk-management strategy for PCB-contaminated sedi-
