Superfund Record of Decision (EPA Region 6): National Zinc Corp., Operable Unit2, Bartlesville, OK., October 2, 1997

摘要

This decision document presents the selected remedial action for the secondoperable unit of the National Zinc Site, in Bartlesville, Oklahoma. This ROD describes the remedial action selected for addressing elevated metals concentrations in surface water and sediments at Operable Unit 2 (OU2) of the National Zinc Site (the Site) in Bartlesville, Oklahoma. The selected remedy is removal of contaminated sediment and offsite disposal for the impacted streams and tributaries. Clean fill will be imported to replace the excavated material in the lower reach of the North tributary. This remedy will allow the excavated sediment (treated as needed) to be transported to an approved offsite disposal facility. Additionally, the natural recovery option will be used for Eliza Creek. If the destruction of the stream habitat will be too great in some areas, then DEQ may choose to limit removal in sensitive portions of the lower reach of the North Tributary.
