Under the authority of the Canadian Environmental Protection Act, 1999 (CEPA 1999), owners or operators of oil sands facilities that meet specified criteria are required to report air pollutant releases to Environment Canada’s National Pollution Release Inventory.  The National Pollution Release Inventory currently tracks over 300 substances or groups of substances that are released to air, as well as water and land, disposals and transfers for recycling.
