Risk management actions

Proposed Regulations Respecting Reduction in the Release of Volatile Organic Compounds (Petroleum Sector)

In May 2017, the proposed Regulations Respecting Reduction in the Release of Volatile Organic Compounds (Petroleum Sector) were published in the Canada Gazette, Part I: Vol. 151, No. 21 - May 27, 2017 for a 60-day public comment period.

If finalized, the regulations would require the implementation of comprehensive leak detection and repair programs at petroleum refineries, upgraders and certain petrochemical facilities. The operators of these facilities would also be required to modify certain equipment components to prevent leaks and to monitor the level of certain volatile organic compounds (VOCs) at facility perimeters. The regulations are expected to reduce releases of VOCs, including petroleum and refinery gases (PRGs).

Proposed Environmental Emergency Regulations, 2016

In October 2016, the proposed Environmental Emergency Regulations, 2016 were published in the Canada Gazette, Part I: Vol. 150, No. 41 – October 8, 2016 for a 60-day public comment period.

The proposed regulations would repeal and replace the current regulations. One key proposed change was the addition of 49 substances to Schedule 1 of the regulations, including 3 natural gas condensates in Stream 4.  Under certain regulated circumstances, the proposed regulations would require reporting on these substances, environmental emergency planning for higher-risk facilities, and reporting of spills or releases involving these substances that are environmental emergencies.

Addition of 3 natural gas condensates to these regulations would contribute to meeting the environmental objective of minimizing environmental exposure to the greatest extent practicable, as outlined in the proposed risk management approach that was published in December 2016.

Adding substances to Schedule 1

Substances in this stream have been added to Schedule 1.
