Risk Assessment Guidance for Superfund. Volume 1. Human Health Evaluation Manual(Part B, Development of Risk-Based Preliminary Remediation Goals)

摘要

The document is one of a three-part series. Part B provides guidance on usingUSEPA toxicity values and exposure information to derive risk-based preliminary remedial goals (PRG) for a CERCLA site. Initially developed at the scoping phase using readily available information, risk-based PRGs generally are modified based on site-specific data gathered during the remedial investigation/feasibility study. The guidance does not discuss the risk management decisions that are necessary at a CERCLA site. The potential users of Part B are those involved in the remedy selection and implementation process, including risk assessors, risk assessment reviewers, remedial project managers, and other decision-makers.
