Remediation and Redevelopment Division reissues Non-Aqueous Phase Liquid Characterization, Remediation, and Management for Petroleum Releases Guidance
The Department of Environment, Great Lakes, and Energy, Remediation and Redevelopment Division (RRD) has updated and reorganized its guidance for the characterization, remediation, and management of petroleum non-aqueous phase liquids (NAPL). It provides current references (e.g., department name, statute, and rules), clarifies RRD’s expectations with NAPL characterization using a multiple lines of evidence approach, clarifies when generic criteria or risk-based screening levels can be utilized, and outlines how to move a site with petroleum NAPL to closure or no further action. In addition, an example multiple lines of evidence evaluation table is provided as an appendix to give all users a tool and an example of how to organize site data for the evaluation of petroleum NAPL in the development of the conceptual site model. Training on the use and applications of the document will be provided in the next few months.
Questions regarding this document may be directed to Nick Swiger, Technical Support Unit Supervisor, at SwigerN@Michigan.gov or 231-429-8926. Questions regarding the application of the guidance to a specific site should be directed to staff in the district office where the site is located.
