Federal Facility Five-Year Review Webinar is a two-hour webinar course that provides an overview of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) five-year reviews. By taking this course, participants will achieve the following objectives:Understand Five-Year Review purpose and regulatory contextLearn how to prepare and conduct a five-year reviewIdentify the information and data needed to support a protectiveness statementAddress emerging contaminants and options available to ensure that the federal agencies address these contaminantsIdentify the different scenarios when EPA makes an independent finding of the protectiveness of the remedyLearn about similarities and differences between federal and private site five-year reviewsThe instructional methodology for this course includes lecture, case studies, and quizzes. There will also be an opportunity for participants to ask questions. The target audience for this course are federal, state, and tribal representatives who work on Federal Facility cleanups. Ideally, students should have a basic understanding the 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).

The U.S. EPA Office of Mountains, Deserts and Plains has launched a new initiative - the Environmental Monitoring and Remediation Technology Assessment Initiative (EMRTAI) - that is focused on innovative technologies to recover critical minerals from waste materials at Superfund legacy hard rock mine and mineral processing sites. The goal of EMRTAI, which is being developed to support stakeholders across the mining industry, is to generate credible data through a quality-driven technology assessment program to promote advancement of innovative technologies and informed decision-making. At present, there are nearly 100 mining or mine-related sites on EPA's Superfund National Priorities List (NPL), and many more sites throughout the U.S. in variable stages of remediation. EMRTAI will advance EPA's mission to protect human health and the environment by assisting technology developers and vendors with performance assessments that target site clean-up and critical minerals recovery technologies as part of sustainable materials management.  Environmental justice is critical to the just treatment and meaningful involvement of all people, regardless of income, race, color, national origin, Tribal affiliation, or disability, in agency decision-making and other Federal activities that affect human health and the environment so that people are fully protected from disproportionate and adverse human health and environmental effects (including risks) and hazards, including those related to climate change, the cumulative impacts of environmental and other burdens, and the legacy of racism or other structural or systemic barriers. EMRTAI will assist public entities such as non-profit organizations, Tribes, industries, businesses, states, individuals, and communities in making better informed decisions when selecting new or existing environmental technologies for use at contaminated sites.  A stakeholder group to support EMRTAI will be forming in July 2024. Please join this webinar to learn more about EMRTAI and how to become involved.

This training class builds on the earlier information for treatment technologies presented in the PFAS 101 CLU-IN training. It provides more in-depth information regarding considerations for implementing integrated PFAS treatment technologies and remediation strategies. This training introduces the concept that achieving site remedial objectives will likely necessitate the implementation of multiple treatment technologies and remediation strategies (i.e., an integrated remedial strategy). Specifically, this training uses a hypothetical conceptual site model to frame the discussion of remedial approaches for PFAS impacted source area soil, source area groundwater, and more dilute groundwater plumes. The training concludes with a discussion of select field implemented and developing disposal and destructive technologies for managing treatment residuals.

Resources and further details for the topics included in this training are in the published PFAS-1 guidance document in Sections 12 and 15 along with referenced tables.

Learning Objectives:
What types of media, sources, and pathways might require intervention and treatment?How are field-implemented PFAS remediation technologies commonly applied?What developing technologies show promise for PFAS treatment?How may integrated remedial strategies be applied?What are the key considerations for applying field implemented and developing technologies?

Resolving Issues Before Formal Dispute is a two-hour webinar course that identifies less formal options to address conflict before going to dispute under a federal facility agreement. This webinar provides project management tips and techniques to address disagreements early in the process . By taking this course, participants will achieve the following objectives:Identify factors that contribute to conflict when working with team members from different agencies;Learn how to prepare a team to handle conflict;Explore tips and techniques to improve communication and come to resolution; and,Understand when formal dispute should be considered.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. This course is part of the Federal Facilities Academy training program.

U.S. Environmental Protection Agency (EPA) and its contractors performing oversight at Superfund Sites review numerical models developed to simulate contaminant transport. An analytical transport model could be used to check the numerical model results but a practical modeling tool based on a 3D analytical solute transport model is not publicly or commercially available. The roles of an analytical model in Superfund oversight are to simulate the general plume behavior; guide the development of, and provide a check for, a more complex numerical solute transport model; and evaluate smaller scale transport such as during natural gradient tracer tests. EPA tasked APTIM to develop an analytical model for solute transport in a three-dimensional aquifer of finite thickness with uniform flow, dual porosity, sorption, sequential decay, and time-dependent source. The new model was verified against existing analytical models for special cases and against numerical models MT3DMS and RT3D, and published in two journal papers. EPA tasked RTI to develop a graphical user interface (GUI) for the model. Example applications are analysis of tracer tests at the Stringfellow Superfund Site and simulation of TCE plume at the Fresno Sanitary Landfill.

This webinar will be focused on MR-QAPP Toolkit, Module 2 - Remedial Actions that was published in March 2023. Presentations will cover Worksheet 11 and how Data Quality Objectives (DQOs) are presented in this new toolkit as well as the new Measurement Performance Criteria (MPCs) and Measurement Quality Objectives (MQOs). There will also be a discussion of managing data deliverables using Delivery Units and Survey Units, and the related Data Usability Assessments (DUAs). Presentations will be suitable for the varied M2S2 webinar audience, which typically includes government, regulator, and contractor attendees, and there will be opportunities for questions and discussion.
