If full recovery was not achieved and significant contamination remains or has moved offsite or there are significant ecological impacts, an expedited Natural Resource Damage Assessment (NRDA) may be considered. Natural resource injury should be established if there is a measurable adverse change in the chemical or physical quality or viability ofa natural resource or if there is impairment of natural resource: services) or uses. Injuries may be quantified at contamination levels above a baseline and go beyond threats to human health and include biologic and ecologic injury and service. `The goal oaf NRDA is to return the lossofnatural resources or natural resource services to the public and to effectively rehabilitate or replace the injured resource or service. Resource injury, spi volume, and type and circumstance of the release will influence or determine the need for an expedited NRDA. 5. Sites with significant residual contamination at closure will be geo-located and reported in UTM (Universal Trans Mercator North American Datum Zone 15) coordinates. ti the policy of the EMU to leave a record that will accurately describe the location, type and amount of such contamination to the extent Known. oezorz 3758.0002 ly2007 |cert13
