The Licensed Remediation Specialist (LRS) training provides continuing education for LRS professionals. The summary for the September 7 session is below.

The presence of light, nonaqueous-phase liquid (LNAPL) can present challenges during the assessment and remediation of petroleum contaminated sites. Additionally, these challenges, whether real or perceived, may hinder or complicate any planned expansion, redevelopment, or reuse of sites (i.e., Brownfield sites). Fortunately, over the past few decades, LNAPL assessment and remedial technologies have evolved along with our understanding of the concerns and risks created by the presence of LNAPL. A variety of technical publications and guidance documents have been published over the years to help practitioners address and manage LNAPL at sites. In 2009, the Interstate Technology & Regulatory Council (ITRC), a state-led organization that promotes innovative solutions for a variety of environmental issues, released a technical/ regulatory guidance document that provides a framework to systematically set appropriate LNAPL remedial objectives based on composition and saturation concerns. The guidance discusses regulatory practices with regard to LNAPL, development of an adequate LNAPL conceptual site model, and identification and selection of appropriate LNAPL remedial technologies. The guidance is designed to facilitate regulatory oversight of LNAPL remediation, streamline remedial technology selection and regulatory approval, enhance communication between stakeholders, and facilitate closure of LNAPL remediation projects.

Following release of the 2009 ITRC LNAPL guidance, multi-day classroom and a three- part Internet based training was developed and offered. This presentation will present a high and mid-level overview and discussion of the ITRC LNAPL guidance and training, particularly with regard to LNAPL conceptual site models, LNAPL site characterization, management objectives and goals, LNAPL remedial technologies and selection of the most appropriate technologies for any petroleum or Brownfield site.
