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

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 1 Stream 2 substance (CAS RN 8002-05-9). 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.

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 proposed Environmental Emergency Regulations, 2016 for emergency prevention, preparedness, response and recovery purposes.

Adding substances to Schedule 1

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

Final screening assessments and risk management approach

Industry-restricted gas oils

In July 2013, the final screening assessment for 2 substances was released and the related notice was published in the Canada Gazette, Part I, Vol. 147, No. 31 - July 27, 2013.

The final screening assessment concluded that these 2 substances do not meet any of the criteria set out in section 64 of CEPA 1999, therefore the Ministers of the Environment and of Health proposed to take no further action on these substances at this time under the act. No proposed risk management approach was prepared.

In May 2012, the draft screening assessment for these substances was released and the related notice was published in the Canada Gazette, Part I: Vol. 146 No. 19 - May 12, 2012 for a 60-day public comment period.
