He previously served as chairman from Dec. 2006 to June 2007.
So far, reaction to Barrett's appointment has been positive.
Officials with the Adirondack Association of Towns and Villages issued a statement late Tuesday, in which they called ORDA a "vital economic engine" for the Adirondack Park.
The release notes that ORDA's venues attract millions-of-dollars in tourism revenue to the park's "fragile economy."
"Gov. Cuomo clearly understands the importance of ORDA, and in Pat Barrett he has made the right choice for chairmanship of the authority," the release states.
AATV says Barrett is "well known" throughout the state for his business savvy and commitment to public service.
"The people of the Adirondacks know him as one of their own," the statement reads. "He knows the Adirondacks, our traditions and the unique challenges we face."
