The course will be moderated by Ken Marra of MassDEP. Mr. Marra will introduce course topics and will lead the panel discussion at the end of the course.
Steve Boynton, the lead author of the 2005 and 2008 LSPA LNAPL White Papers and LSPA lead for the LNAPL work group, will provide an overview of the LSPA White Papers relating to improved LNAPL assessment techniques and recommended regulatory changes.  
Ken Marra will then provide a detailed review of the 2014 MCP Amendments, followed by a presentation of recommendations and implementation challenges related to the 2016 MassDEP Policy "Light Nonaqueous Phase Liquids (LNAPL) and the MCP: Guidance for Site Assessment and Closure" (policy #WSC-16-450).
Wesley Stimpson, former LSP and LSPA Past President, has been reviewing the content of Permanent Solutions, and Activity and Use Limitations (AULs) for LNAPL sites since promulgation of the 2014 LNAPL regulations. Mr. Stimpson will provide a review of his findings and recommendations for appropriate submittals.
Steve Gaito, a member of the ITRC Site Characterization and ASTM NAPL in Sediments teams, will present the "Simplified Method" and the alternative "Multiple Lines of Evidence" approach.  Mr. Gaito will also discuss Natural Source Zone Depletion and Alternative LNAPL Transmissivity test procedures.
A round table discussion moderated by Ken Marra of MassDEP will follow formal instructor presentations.
