Co-host Matthew Wallace just completed his first PFAS sampling!

Here's a breakdown of what we wanted to know from the EHS&S Professional:

We thought a little breakdown of 

1. Do you do much sampling generally?
2. Without telling us who the client was, or giving away too much, can you tell us what the facility was, what it was like?
3. What kind of sampling was this?
4. What was the preparation that you have to for PFAS specifically?
5. What were the special considerations for this particular event? Things you thought about doing, changes up

Join hosts Tom Simmons and Matthew Wallace, joined by HRP's EHS&S Practice Leader, Jackie Baxley, as we break down the new deadline for PFAS TSCA reporting.

EPA announced an interim final rule which extended the dates of the reporting period for data submissions for the TSCA PFAS reporting rule. Submissions are now due by October 13, 2026, for most manufacturers. Small businesses reporting data solely on importing PFAS contained in articles have until April 13, 2027, to submit reports. This rule provides much needed time for the regulated community to assess its manufacturing (including import) from 2011 to 2022 relative to PFAS.  Prior to this rule being published, the reporting period was set to open this July with reports due January 11, 2026.

For more information on this rule, refer to HRP’s webinar presented February 2025: https://www.youtube.com/watch?v=jNalxzfPxog
