Mr. Chair, the federal government, indeed, has some environmental performance agreements in place with the base metals smelting and refining sector.
In terms of a federal standard, Health Canada is currently developing a health-based ambient air quality objective for arsenic. There is not one in place at the moment, but we expect that this tool will be able to be used by the federal government, provincial governments and industry to help establish the level that's appropriate in order to manage arsenic health risks.
