ABSTRACT
Through the process of natural resource damage assessment (NRDA), certain public agencies have the authority to recover monetary damages from parties responsible for injury to natural resources from a discharge of oil or a release of a hazardous substance. Computer simulation models have been developed as simplified procedures for these natural resource trustees to use in calculating damages without undertaking extensive field studies. The revised Natural Resource Damage Assessment Model for Coastal and Marine Environments (NRDAM/CME) and the Natural Resource Damage Assessment Model for the Great Lakes Environments (NRDAM/GLE) are being developed to serve an expanding user community of public natural resource trustees. These tools may enable natural resource managers to expedite settlements and execute environmental restoration.
To estimate the potential use of the NRDA models for oil spills, the authors have developed a set of candidate spill occurrences based on the historical record. Representing an estimated 337 applicable spill events in the subject year, 121 model runs generated damage figures ranging from zero to more than half a million dollars.
