About

We invite you to join the open session of our fourth committee meeting. At the meeting we will hear from the U.S. Department of Veterans Affairs (DVA) on implementation of their 2014 directive. We will also hear about the role of building and plumbing codes in Legionella management. There will be time for public comments around 4:30 pm.

You can sign up to give a public comment in person either while registering or in person at the meeting. You can also submit public comments directly to the committee by emailing them to rchappetta@nas.edu.

Limited seating is available for in-person attendance, with more spots available for attending remotely via Zoom. Registration is required in either case. The session will be recorded and posted online like our previous meetings.

Please contact Remy Chappetta at rchappetta@nas.edu with questions about meeting logistics.
