Carper added that the board had voted to not waive the debt when the item was not on its agenda, which is a violation of the state's Open Meetings Law.
Carper himself is a member of the Regional Development Authority's board, but was absent at the meeting when the issue was addressed.
He added that the issue would again be brought up at a meeting after being publicly noticed.
"We'll be dealing with this again," Carper said. "We'll work this out."
Commissioners also briefly discussed a $660,000 U.S. Homeland Security grant provided to the Kanawha-Putnam Emergency Planning Commission.
The money will be used to purchase 16 outdoor emergency sirens in Kanawha County, said Dale Petry, director of Kanawha County's office of Homeland Security and Emergency Management.
The sirens should be installed by May. One of the sirens will be placed outside the county courthouse, Carper said.
Commissioners also unanimously approved raises for office employees during Thursday's meeting. They had previously agreed to allocate raises to each elected official's office based on a percentage of total payrolls.
Commissioners agreed to distribute around $56,000 in raises to employees in their office ranging from custodians to the county manager.
This was done despite the fact that the commissioners had originally voted to allocate $49,297 to their employees during a previous meeting.
However, Carper pointed out that the commission's office was still within budget despite the higher total because some unfilled positions have been left vacant.
County Manager Jennifer Sayre received a 5 percent raise, bringing her annual salary from $111,000 to $116,550.
Fontalbert received a 4 percent raise, bringing his annual salary from $79,280 to $82,451.
County Attorney Marc Slotnick also received a 4 percent raise, bringing his annual salary to $63,440.
