ITRC Connecting the Science to Managing LNAPL Sites, a 3 Part Series - Part 3: Mar 1, 2022, 1:00PM-3:15PM EST (18:00-20:15 GMT). The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you: build upon your understanding of LNAPL behavior in the subsurface (Part 1), develop your LNAPL conceptual site model and LNAPL remedial goals (Part 2), and select/implement LNAPL technologies (Part 3). After this training series, the expectation is that you will have the skills and understanding to use ITRC science-based resources to improve decision making at your LNAPL sites. For regulators and other government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs. It is expected that participants will attend this 3-part training series in sequence. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live. An archive of parts 1 and 2 is available at https://clu-in.org/conf/itrc/LNAPL-3_010920/.

ITRC Optimizing Injection Strategies and In situ Remediation Performance - Mar 3, 2022, 1:00PM-3:15PM EST(18:00-20:15 GMT). ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) and this associated training course to identify challenges that may impede or limit remedy effectiveness and discuss the potential optimization strategies, and specific actions that can be pursued, to improve the performance of in situ remediation by: refining and evaluating remedial design site characterization data; selecting the correct amendment; choosing delivery methods for site-specific conditions; creating design specifications; conducting performance evaluations, and optimizing underperforming in situ remedies. The target audience for this guidance and training course is: environmental consultants, responsible parties, federal and state regulators, as well as community and tribal stakeholders. This training will support users in efficiently and confidently applying the guidance at their remediation sites. An optimization case study is shared to illustrate the use of the associated guidance document. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live.

Federal Facilities Online Academy: Record of Decision (RODs) and More at Federal Facilities - Mar 9, 2022, 1:00PM-3:00PM EST (18:00-20:00 GMT). RODs (Records of Decision) and More at Federal Facilities is a two-hour webinar course that will provide an overview of how early and interim actions, adaptive management, RODs, Explanations of Significant Differences (ESDs), and ROD Amendments are used at Federal Facilities. By taking this course, participants will achieve the following objectives: Understand how removal actions, sampling and analysis plans, and decision documents are used at Federal Facilities; Learn about the Environmental Protection Agency (EPA) and Department of Energy (DoE) Joint Policy Memo; Identify how Interim Actions can be used as part of an overall cleanup strategy; and, Learn the process for changing remedies after a ROD is issued. The instructional methodology for this course includes lecture, group discussions, case studies, and quizzes. The target audience for this course is federal, state, and tribal representatives who work on Federal Facility cleanups. Ideally, students should have a basic understanding of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process. This course is part of the Federal Facilities Academy training program. Please consider registering for other Federal Facility Academy courses and obtain a certificate upon completion of the entire Federal Facility Academy series (12 courses total).

ITRC Sustainable Resilient Remediation (SRR) - Mar 15, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Extreme weather events and wildfires are increasing and impacting hazardous waste sites. The primary goal of cleanups, which is protecting human health and the environment, is undermined. Confronted with these risks, environmental professionals should assess, and design remedies that are sustainable and resilient. Sustainable resilient remediation (SRR) is an optimized solution to cleaning up and reusing a hazardous waste site that limits negative environmental impacts, maximizes social and economic benefits, and creates resilience against increasing threats. The objective of the ITRC Sustainable Resilient Remediation (SRR-1) is to provide resources and tools for regulators, stakeholders, consultants, and responsible parties to help integrate sustainable and resilient practices into remediation projects. This guidance updates the Interstate Technology and Regulatory Council's (ITRC) Technical and Regulatory Guidance: Green and Sustainable Remediation: A Practical Framework (ITRC 2011a) and includes a strong resilience component to address the increasing threat of extreme weather events and wildfires. Recommendations for careful and continuous consideration of the social and economic costs and benefits of a cleanup project are included. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live.

ITRC TPH Risk Evaluation at Petroleum-Contaminated Sites - Mar 17, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The basis for this training course is the ITRC guidance: TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018). The guidance builds on long-standing and current research and experience, and presents the current science for evaluating TPH risk at petroleum-contaminated sites. As a participant in this training you should learn to: recognize the ITRC document as a go-to resource for evaluating TPH risk at petroleum-contaminated sites, recognize how TPH-impacted media interacts with the environment and changes over time, select appropriate analytic method(s) to match site objectives, and apply the decision framework to determine when a site-specific target level may be more appropriate than a generic screening level for TPH. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live.

Military Munitions Support Services - Life of a CSM: Concept to Response Complete - Mar 23, 2022, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This series will explore the development and use of a CSM throughout the remedial response process. Special emphasis will be placed on using the CSM as a mechanism for systematic project planning and acquisition from Remedial Investigation through Remedial Action. Presentations will address lessons learned, best practices, and data needs for characterization, risk assessment, alternatives development, cost estimating, and contracting.

Green Remediation Best Management Practices: Pump and Treat Systems (EPA 542-F-21-029). In line with the renewed Agency emphasis on sustainability and climate change resilience and mitigation, the Superfund Program is proceeding to update the very popular green remediation best management practice (BMP) fact sheets for the most common remedies in the Superfund program. The goal of these fact sheets is to share technical information on best practices that build sustainability into contaminated site cleanup operations across the portfolio of remediation approaches. The green remediation (GR) fact sheet on pump and treat systems has been one of the most popular "GR factsheets," with over 10,000 downloads since it was first released. The updated fact sheet includes new BMPs gathered from projects across the country and describes how climate resilience is being built into our sites to ensure continued remedy protectiveness. The fact sheet also highlights synergies between green remediation and climate adaptation practices, where one action provides both greenhouse gas (GHG) mitigation and climate resilience. Examples are BMPs involving use of renewable energy, green infrastructure or carbon sequestering vegetation that mitigate GHG emissions and add resilience to ongoing climate change. The fact sheet also highlights how advanced practices gleaned from Superfund's optimization and technical support work, such as reclaiming and reusing treated water for beneficial purposes, help reduce the environmental footprint of remedies.
