What is a NRDA?
Natural Resource Damage Assessment is a legal and technical process enforceable under U.S. state and federal laws for determining the compensation owed to the public for injuries to ecological and socioeconomic ecosystem services caused by an oil spill or hazardous substance(s) released into the environment.
Internationally Recognized Expertise
Montrose experts have advised clients on over 100 NRDA-related projects since 1990, including the Exxon Valdez and the 2010 Deepwater Horizon incidents. Our experience involves incidents affecting coastal marine, freshwater river and stream, and terrestrial habitats across over 35 U.S. states and internationally.
We design and implement technical and science-based strategies that satisfy legal and regulatory obligations while helping our clients manage and limit their NRDA liability. We prepare expert reports and testimony in litigation to support injury determinations and restoration recommendations.
