Federal disaster officials have agreed to chip in $22.8 million to help California pay the estimated $500 million cost of the Oroville Dam crisis. Victor Inge, a spokesman for the Federal Emergency Management Agency, said Wednesday that the reimbursement is to cover some costs associated with the emergency as well as for removing the massive pile of debris that washed down from the spillway and plugged the Feather River channel below the dam. Inge said the state’s requests for reimbursement still are being reviewed, and additional payouts could take several more months.
