Upcoming ITRC Documents

Implementing Advanced Site Characterization Tools Guidance Document

In December 2019, ITRC will release a guidance document on Implementing Advanced Site Characterization Tools (ASCTs)! ASCTs are valuable resources that expand and enhance the development of a conceptual site model. Although these tools have been available for several years, they often are not used because users perceive them to be expensive and unavailable or do not understand how ASCTs work and how to interpret the acquired data. This document will improve stakeholders' ability to select and use ASCTs, as well as improve their ability to use the data gathered by ASCTs to evaluate cleanup options.

PFAS Explainer Videos

By the end of 2020, the PFAS team will release a series of explainer videos that cover various PFAS topics for non-experts.

Optimizing In Situ Remediation Performance & Injection Strategies Guidance Document

In March 2020, ITRC will release a guidance document on Optimizing In Situ Remediation Performance & Injection Strategies! There are many types of in situ remediation amendments and remplacement technologies, and each site provides unique challenges that can limit the effectiveness of in situ remediation. This document identifies remedy challenges and provides recommendations for making improvements and measuring remedy effectiveness.

1,4-Dioxane Fact Sheets

In Spring 2020, ITRC will release six fact sheets on 1,4-Dioxane! The fact sheets will cover history and use, regulatory framework, fate and transport, sampling and analysis, toxicology and risk assessment, and remediation and treatment technologies.

Risk Communication Toolkit

In Spring 2020, ITRC will release a toolkit on Risk Communication! The ability to communicate potential risks to human health and the environment is a vital skill towards facilitating community participation and decision-making. This toolkit provides information for developing comprehensive engagement strategies using a risk communication plan that will be particularly useful for communities dealing with rapidly evolving science and emerging environmental concerns such as PFAS, 1,4-Dioxane, and Harmful Cyanobacterial Blooms.

Fall Team Meetings Recap

1,4-Dioxane

In October, the 1,4-Dioxane team had a very productive meeting in St. Paul, Minnesota. The team got together for two days to plan and work on fact sheets, the guidance document, and future training activities. The team reviewed and discussed feedback and comments received on the 1,4-dioxane fact sheets. The team also reviewed comments and suggestions for the draft guidance document. The History and Use, Sampling and Analysis, Fate and Transport, Regulatory Framework, Remediation and Treatment Technologies, and Toxicology and Risk Assessment workgroups had time both days to work in smaller groups on sections of the guidance document and on fact sheets. The guidance document will be ready for external review next summer and the 1,4-Dioxane fact sheets will be finalized early 2020.

Green and Sustainable Remediation with Resiliency to Extreme Weather Events and Wildfires

In September, the GSR/Resiliency team held its first meeting in Baltimore, Maryland. On the first day, presentations and panel discussions provided grounding for all team members and allowed everyone to brainstorm and form a consensus about the final products. The updated ITRC guidance is now expected to include an online road map, toolkit, and fact sheets covering key topics. Subgroups were formed and subgroup members determined their preliminary objectives, goals, and approaches for the following topics: Importance and Value, Resiliency Guidance, Integrating Resiliency with GSR, Technical and Regulatory Barriers and Opportunities, Beneficial Reuse, and Best Management Practices.

Harmful Cyanobacterial Blooms

In October, the Strategies for Preventing and Managing Harmful Cyanobacterial Blooms (HCB) team met in St. Paul, Minnesota. The meeting began with an overview of the concepts for the team’s webpages, then moved into a general overview of the existing document outline to determine if there were topics which had not been included on the original outline. As this was primarily a working meeting for the team, the remainder of the meeting time was spent on writing and revising the various document sections in preparation for the first team review. This meeting provided a great opportunity for face-to-face work prior to the deadline for the team's first draft in early November.

Implementing Advanced Site Characterization Tools

In September, the ASCT team met in Cincinnati, Ohio to work on their training resources. The team spent two days finalizing their scripts and filming their video modules, which will be available later this year. Their document will be released in December 2019.

Incremental Sampling Methodology (ISM) Update

In October, the Incremental Sampling Methodology (ISM) Update team had a productive meeting in St. Paul, Minnesota. In their efforts to revise the 2012 ISM guidance document, team members reviewed comments provided on the internal draft version of the document. Members participated in a lively group discussion about refining their original objectives to ensure agreement and consistency throughout the meeting. Later the subgroups worked together to review specific section comments to identify those requiring input from the larger group. Small group breakout discussions were very productive and the Team completed the review of all internal comments and outlined follow-up steps by the end of their meeting.

Optimizing In Situ Remediation Performance & Injection Strategies

In September, the In Situ team met in Albuquerque, New Mexico to work on addressing comments received on their guidance document during external review. They also spent time reviewing their online training resources and practicing for the delivery of their online classes which will take place early next year!

PFAS

In September, about 80 team members attended the PFAS team fall meeting in Albuquerque, New Mexico. The team convened in their subgroups to work on the individual sections of the PFAS guidance document. They also made significant progress on the Risk Communication Toolkit and the slide decks for the PFAS video training modules. Co-Team Leaders presented new initiatives, including discussion of the scope for the extended PFAS team in 2020. The PFAS team has conducted 15 in-person workshops in 2018 and 2019, providing training to more than 2,400 people. Currently, the PFAS technical and regulatory guidance document is in the technical editing process and will be published in March 2020.

Vapor Intrusion Mitigation

In August, the Vapor Intrusion (VI) Mitigation Training team had a very productive meeting in Chicago with over 40 attendees! The team divided into six subgroups: VI Mitigation Conceptual Site Models, Public Outreach & Communication, Remediation & Institutional Controls, Active Mitigation Technologies, Passive Mitigation Technologies, and Rapid Response/Ventilation. The subgroups began developing a series of supplemental documents including fact sheets, technology information sheets, and checklists that will help regulators, consultants, and stakeholders navigate the VI mitigation process from beginning to end. Their next in-person meeting will be on November 18-19 in Long Beach, California, where the team will continue revising their documents.

ITRC Board of Advisors

New Board Member

ITRC welcomes its newest Board member Rebecca Higgins from the Minnesota Pollution Control Agency! Rebecca will serve in the State Association Representative starting in January 2020. Before her position on the Board, Rebecca was the State Point of Contact from Minnesota and was a Co-Team Leader for two ITRC teams: Green and Sustainable Remediation (2009-2011) and Stormwater BMPs (2016-2018).

ITRC will say goodbye to two Board members as they complete their terms at the end of 2019. The ITRC State Association member Ken Zarker from Washington Department of Ecology served on the Board for six years. The ITRC Stakeholder Representative Kathy Owens from the Eastern Idaho Community Action Partnership also served on the Board for six years. Their presence will be greatly missed but don't worry, they will still remain involved in ITRC!

2020-2024 ITRC Strategic Plan

The ITRC Board of Advisors met at Utah DEQ in Salt Lake City for their 2019 Summer Board Meeting. At the meeting, the Board finalized its 2020-2024 Strategic Plan.
