Northport Residential Yards and Common Use Areas
The Northport properties are located near the former Le Roi Smelter in northeast Washington state. In 2003/2004, EPA conducted a RSE and fund-lead removal action addressing contaminated soils at the former smelter and nearby residential areas located within Northport town limits. The TCRA action level for lead in soil was 1,000 mg/kg. In 2015, 2017 and 2018 removal actions were conducted by Teck American Incorporated with EPA oversight at residential properties and a Tribal allotment located outside the Northport town limits using a removal action level for lead in soil of 700 mg/kg.
2019 Removal Site Evaluation
In 2019, EPA conducted a RSE of the properties located within Northport town limits that were sampled in 2003/2004 that contained lead in soil at concentrations near or above the action level of 700 mg/kg, but at which no soil removal action was taken. Based on the findings of the 2019 RSE, 16 residential properties and common use areas were identified as meeting the established criteria for a TCRA.
2020 Time-Critical Removal Action
This removal action addresses the 16 properties located within Northport town limits that contain lead in soil at concentrations near or above the action level of 700 mg/kg, but at which no soil removal action was taken. The primary objective of this action is to eliminate or reduce the potential human health threats posed by exposure to lead and arsenic, including direct contact, ingestion, and inhalation pathways.
