- FACA Web site re-opened
- While the Federal Advisory Committee Act (FACA) formed by EPA to
obtain advice and recommendations on integrated approaches for implementing
(NAAQS) for ozone and particulate matter is over, the information
obtained during the process is considered valuable for an initiative
to implement the 8-hour standards. The FACA Web site is re-opened
to present what was done during the FACA process as a aid to implementing
the new standards.

- FACA Web site closed
- Information concerning the Federal Advisory Committee Act (FACA)
formed by EPA to obtain advice and recommendations on integrated approaches
for implementing (NAAQS) for ozone and particulate matter, is not

Web site to be closed after presenting historical, static data well
beyond the life of the FACA committees.
