Natural Resource Damage 

Assessment and Restoration

The primary aim of the U.S. Department of the Interior's (Department) Natural Resources Damage Assessment and Restoration Program (NRDAR) is to restore natural resources injured as the result of oil spills or hazardous substance releases.  The program assesses the damages and injuries to natural resources entrusted to the Department and negotiates legal settlements or takes other legal actions against the responsible parties for the spill or release.  Funds from these settlements are then used to restore the injured resources at no expense to the taxpayer.  Settlements often include the recovery of the costs incurred in assessing the damages.  These funds are then used to fund further damage assessments.
