Project Overview

Who is Teck American and why are they involved?

Teck American is a U.S. subsidiary of a Canadian company whose predecessor began operation of a metals smelting facility in Trail, British Columbia, Canada in 1892. Granulated slag, a metal-containing by-product of smelting, was discharged into the Columbia River from the Trail facility beginning in the early 1930's until 1995, in compliance with Canadian law. Aware that the facility was still viewed by some as a source of air and water pollution, the company spent $1 billion retrofitting the facility and installing truly state-of-the-art pollution abatement equipment. The issue of legacy discharges remained and needed to be addressed.

Recent studies done by U.S. federal and state agencies showed elevated levels of metals in Upper Columbia River sediments. Due to questions about possible health and environmental impacts, Teck American volunteered to conduct further studies to determine if any detrimental impact from its Trail operations may have occurred, and if so, to address areas with unacceptable risk for which it is responsible.

Teck American reached an agreement with the EPA on June 2, 2006 to fund and conduct these comprehensive human health and ecological risk assessments. The human health risk assessment is being conducted by the EPA.
