Under the Oil Pollution Act, federal, tribal, state, and any other person can recover removal costs from a responsible party so long as such entity has incurred costs from carrying out oil removal activities in accordance with the Clean Water Act National Contingency Plan. Reimbursement claims must first be made to the responsible party. If the potentially responsible party refutes liability or fails to distribute the reimbursement within 90 days of the claim, the claimant may file suit in court or bring the claim to the Oil Spill Liability Trust Fund described below. In some instances, claims for removal cost reimbursement can be initially brought to the Oil Spill Liability Trust Fund thus sidestepping the responsible party. For example, claimants advised by the EPA, governors of affected states, and American claimants for incidents involving foreign vessels or facilities may initially present their claims to the Oil Spill Liability Trust Fund. When claims for removal cost reimbursement are brought to the fund, the claimant must prove that removal costs were sustained from activities required to avoid or alleviate effects of the incident and that such actions were approved or directed by the federal on-scene coordinator.
