| This document was produced by the Interstate Technology and Regulatory Council (ITRC). It provides practical information and guidance on how to systematically evaluate and manage uncertainty associated with the remediation process by using RPO as a tool. Its primary goal is to provide information and tools to help ensure that the remediation process is progressing toward site cleanup objectives that are both acceptable and feasible and that selected remediation approaches attain those objectives and remain protective of human health and the environment. This document provides guidance on what could and should be included in an effective RPO proposal or program, including what RPO is, the regulatory framework that RPO must operate within, and references that provide examples of successful RPOs and resources for further examination of RPO. |
