ITRC Public Community Documents

Thank you for participating in the External Review of a comprehensive guidance document prepared by the ITRC Tire Anti-degradant (6PPD) Team! The review/comment period for this document starts Tuesday, February 13th and ends Friday, March 29, 2024.

There are two documents uploaded to this library:

1. ITRC Tire Anti-degradant (6PPD) Draft Work Product for External Review – PDF file containing instructions for review (provided upfront), followed by the narrative text, tables, and references in this comprehensive guidance document
2. ITRC Tire Anti-degradant (6PPD) Work Product Comment Spreadsheet – Editable spreadsheet for capturing your comments electronically (see instructions in previous document)

Document Intent/Goal

The work products of the ITRC Tire Anti-degradant (6PPD) team have been prepared to provide baseline knowledge on the tire anti-degradant 6PPD and its degradation product of concern (6PPD-quinone or 6PPD-q) in terms of the following:

· background, history, and basis of concern
· physical properties, fate and transport, and sampling and analysis methods
· solutions to mitigate and manage the impacts on human health and the environment, and
· an overview of information gaps and data needs for continued research.

This information has been tailored to the needs of state program personnel tasked with making informed decisions regarding 6PPD-q as an emerging contaminant.  These documents are also intended to be useful to consultants interfacing with regulatory agencies regarding 6PPD and 6PPD-q. Additionally, these documents should be helpful to public stakeholders and tribes with needs to manage the impacts of these chemicals.

Please contact the Tire Anti-degradant (6PPD) Program Advisor (Steve Brauner; sbrauner@environmentalworks.com) with any questions, comments, concerns, or technical challenges when accessing or commenting on these documents.
