Evaluating LNAPL Remedial Technologies for Achieving Project Goals. Technical/Regulatory Guidance.

摘要

This guidance provides a framework to help stakeholders select the best-suited LNAPL remedial technology for an LNAPL site and will help the regulator and others understand what technologies apply in different site situations. Seventeen LNAPL remedial technologies are considered in this guidance, some of which are more innovative or less proven as an LNAPL remedial technology than others. The framework advocates selecting LNAPL remedial technologies to achieve specific LNAPL remedial objectives that are set to address the specific LNAPL concerns identified at the LNAPL site. This guidance also discusses regulatory practices which may foster better completion of LNAPL remediation, including the important step of developing an adequate LNAPL conceptual site model to guide the setting of LNAPL remedial objectives and remedial technology selection. It is anticipated that use of this guidance will facilitate regulatory oversight of LNAPL remediation, streamline remedial technology selection and regulatory approval, enhance communication between stakeholders, and facilitate closure of LNAPL remediation projects.
