In addition to environmental lead contributions from historical use of products such as lead-based paint and leaded gasoline, Trail is home to one of the world’s largest lead and zinc smelting and refining facilities, in operation for over one hundred years. While significant operational improvements have been made to reduce emissions from process stacks and fugitive sources (buildings, stockpiles and roadways), lead and other metals in dust have been dispersed in the Trail area.

Continuous improvement is a key component of Teck Trail Operations Environmental Management System (ISO14001) and emissions reduction activities continue.
