The Minister of the Environment and the Minister of Health were proposing to add two liquefied petroleum gases (LPGs) (petroleum gases, liquefied, CAS11 RN 68476-85-7, and petroleum gases, liquefied, sweetened, CAS RN 68476-86-8)  to Schedule 1 (List of Toxic Substances) of the Canadian Environmental Protection Act, 1999 (CEPA). Health Canada and Environment and Climate Change Canada conducted a joint scientific assessment for the two LPGs and published a notice summarizing the scientific considerations of the final screening assessment for these substances in the Canada Gazette, Part I, on February 25, 2017.

The final screening assessment concluded that these two LPGs meet the criteria under paragraph 64(c) of CEPA as they are entering or may enter the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health. The exposure sources of concern identified in the assessment are based on the release of the LPGs in fugitive air emissions from various activities such as distillation, cracking or reforming processes at petroleum refineries.
