In its earliest years, Metro 4 operated with assistance of a training coordinator and a partnership with the University of Florida to administer a training grant for the southeastern agencies.

In 2001, Metro 4 determined that it was desirable to establish permanent offices in the Atlanta, Georgia area in collaboration with its sister agency, Southeastern States Air Resource Managers, Inc.

In November of 2001, Metro 4 and SESARM voted to hire a full-time executive director and other necessary staff in the Atlanta area to support the needs of their member agencies.

In early 2002, Metro 4/SESARM’s offices were temporarily located in the offices of the Georgia Environmental Protection Division’s Air Protection Branch.

Beginning June 1, 2002, Metro 4/SESARM began to occupy their permanent offices at 526 Forest Parkway, Suite F, Forest Park, Georgia 30297-6140.
