Stream 2 (Industry-Restricted) substances in the Petroleum Sector Stream Approach

Stream 2 substances for the Petroleum Sector Stream Approach were identified during the initial triage as industry-restricted substances, which are substances that may be transported off refinery, upgrader or natural gas processing facility sites to other industrial facilities but that do not reach the public market in the form originally acquired. Refer to the Petroleum Sector Stream Approach Substances List.

Risk management actions

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

In November 2020, the Reduction in the Release of Volatile Organic Compounds Regulations (Petroleum Sector) were published in the Canada Gazette, Part II: Vol. 154, No. 23 - November 11, 2020.

The regulations require the implementation of comprehensive leak detection and repair programs at petroleum refineries, upgraders and certain petrochemical facilities. The operators of these facilities are also required to ensure that certain equipment components are designed and operated in a manner that prevents leaks, and to monitor the level of certain volatile organic compounds (VOCs) at facility perimeters. The regulations will reduce releases of VOCs, including petroleum and refinery gases (PRGs).

In May 2017, the proposed regulations were published in the Canada Gazette, Part I, Vol. 151, No. 21 – May 27, 2017 for a 60-day public comment period. Comments and information received during the comment period were considered in the development of the final regulations.

Environmental Emergency Regulations, 2019

In March 2019, the Environmental Emergency Regulations, 2019 were published in the Canada Gazette, Part II: Vol. 153, No. 5 – March 6, 2019.

The regulations repeal and replace the former regulations. One key change was the addition of 33 substances to Schedule 1 of the regulations, including 1 Stream 2 substance (CAS RN 8002-05-9). Under certain regulated circumstances, the regulations 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.

CAS RN 8002-05-9 has not yet been assessed with regards to the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), therefore a conclusion concerning these criteria has not yet been reached. However, this substance does meet the criteria set out in section 200 of the Act. Therefore, it was included in the Environmental Emergency Regulations, 2019 for emergency prevention, preparedness, response and recovery purposes.

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. Comments and information received during the comment period were considered in the development of the final regulations. Comments and the Government's responses are provided in the summary of public comments received on the proposed Environmental Emergency Regulations, 2016.

Adding substances to Schedule 1

Four substances in this stream have been added to Schedule 1.

• Final order adding 4 Stream 2 industry-restricted petroleum and refinery gases and 40 Stream 1 site-restricted petroleum and refinery gases (44 substances): Canada Gazette, Part II: Vol. 150, No. 20 – October 5, 2016
