Sayre and other county staff then contacted the Sissonville Fire Department to ask for a list of all the agencies that responded, Sayre said. The department provided the list and the county contacted the agencies to get a total on expenses, she said.
The county then submitted the list of expenses to NiSource, Sayre said.
"That amount didn't have any expenses that weren't incurred by taxpayers," Carper said.
The county will submit a supplemental expense sheet if employees discover other expenses, he said.
The check only covers expenses by public agencies and does not deal with private property damage, Carper said.
However, the company continues to work with residents whose property was damaged in the December explosion.
A pipeline under I-77 ruptured and exploded on Dec. 11. No serious injuries occurred during the incident, but four homes were completely destroyed in the explosion.
Numerous others were damaged and residents in the area were forced to live in a local hotel while the damage was assessed.
Interstate 77 and County Route 21 were both closed during the incident.
