Background

The final screening assessment report for PREPOD, published in the Canada Gazette, Part I, on September 10, 2011, concluded that PREPOD is “toxic” as defined under the Canadian Environmental Protection Act, 1999 (CEPA). The substance was added to the List of Toxic Substances in Schedule 1 of CEPA on December 14, 2016.

A proposed pollution prevention (P2) planning notice in respect of PREPOD was published in the Canada Gazette, Part I, on July 14, 2018 for a 60-day comment period. Three comments were received from industry. Similar comments have been grouped and answered with a single response. All comments received were taken into consideration, and, where appropriate, reflected in the final P2 planning notice.

The final notice was published on June 15, 2019.

The notice applies to owners or operators of facilities within the chemical manufacturing or rubber products manufacturing sectors, that in 2019 or any year thereafter, have an industrial effluent and that manufacture or use PREPOD, or a mixture or compound containing PREPOD, in a quantity greater than 100 kg per calendar year.
