Normally, BRIM pays about $70 million in claims a year, so the storm-related increase is significant.
As of early October, the board had paid about $260,000 in claims. That figure is modest mainly because the Federal Emergency Management Agency may cover some of the claims BRIM has received.
BRIM Executive Director Chuck Jones said the insurer would not pay a claim until it is assured the claim will not be covered by FEMA.
The state parks system filed the largest single claim, $667,000, with BRIM.
"The state park systems were the hardest hit because the June 29 storm occurred right before the July 4 weekend," Jones said. "So they had damage to the buildings, the lodges - they lost income because of visitor cancellations, so it had the disruption of their revenue."
The U.S. Farm Service Agency estimates West Virginia suffered $2 million in agricultural losses related to the derecho, almost all in farm buildings and equipment, said state agriculture department spokesman Buddy Davidson.
FEMA already has paid $2 million to West Virginians who suffered losses during the storm, though that figure continues to rise. The agency also has paid several million dollars to government agencies, but those costs may overlap with other figures.
Some other figures in this article may overlap slightly, although there are other costs like ruined food, lost work time or property damage that did not result in insurance claims and are not accounted for.
There are other, smaller costs from the summer storm: Frontier Communications expects nearly $6 million in damages and West Virginia American Water reported $750,000 in storm-related repairs.
The overall effect on the state's tax collections may be minimal, said Deputy Revenue Secretary Mark Muchow.
"There was likely some loss of labor income for certain hourly workers during a few days after the June storm," he said in an email.
"However, the clean-up efforts also produced some additional labor income for other workers. The biggest loser is the electric utility company with the loss of customer revenue coupled with added cleanup and repair costs. Lower regional electric power consumption could have some marginal impact upon coal and natural gas energy suppliers."
But year-to-date sales tax collections are running slightly ahead of estimates. Personal income tax collections are slightly behind estimates, although that's "due to lower employment within the coal industry," he said.
