When the two-year agreement was approved in June, an attorney for the company told the commission that the company was considering adding about 40 jobs in Putnam County and might ask for an additional PILOT agreement in the future.
Tillis said he didn't vote for the executive session because he doesn't support PILOT agreements in most cases and thinks they should be negotiated in public.
"They need to explain why they would go elsewhere in a public forum, not in an executive session," Tillis said.
Tillis, the only Democrat on the commission, is serving the sixth and final year of his term. He is not running for re-election.
"My concern is we've got a budget that we struggled with this past year," Tillis said.
Tillis also said Putnam County is a strong draw for businesses without the added incentive of tax breaks because of the already low tax rates and strong school system.
"There's a ton of existing businesses that have been here that helped build this county to what it is today," Tillis said. "The school system is the No. 1 driver for companies wanting to locate here. We've got one of the best in the state... and that was built by existing businesses."
Walton would not confirm the identity of the company or the topic of the planned negotiations or comment on the matter.
Earlier in the meeting, Walton told commissioners that another company with a recently approved PILOT agreement, Ludowici, is making progress on their site prep and construction. Walton said Ludowici would bring about 40 jobs to the county.The Putnam County Commission meets the second and fourth Tuesday of each month at the county courthouse in Winfield. All meetings are open to the public.
