Guidance document for responding to the Notice with respect to potentially industry-limited high priority petroleum substances published on July 25, 2009
This document provides guidance for responding to the Notice with respect to potentially industry-limited high priority petroleum substances. This notice was published in the Canada Gazette, Part I, on July 25, 2009, pursuant to paragraph 71(1)(b) of the Canadian Environmental Protection Act, 1999 (CEPA 1999). The guidance document is made available for information only and in case of discrepancy between this document and the notice or the Act, the notice and the Act take precedence.
The Domestic Substances List (DSL) includes substances that were, between January 1, 1984, and December 31, 1986, in Canadian commerce, used for manufacturing purposes, or manufactured in or imported into Canada in a quantity of 100 kg or more in any calendar year. Types of substances on the DSL include simple organic chemicals, pigments, organometallic compounds, surfactants, polymers, metal elements, metal salts and other inorganic substances, products of biotechnology as well as substances that are of “Unknown or Variable Composition, complex reaction products, or Biological materials” (referred to as UVCBs).
As required by CEPA 1999, the Minister of the Environment and the Minister of Health completed, in September 2006, an exercise to sort or “categorize” all 23,000 existing substances on the DSL in order to determine which substances require further attention in the form of assessment, research and/or measures to control their use or release. There were approximately 4,000 chemical substances identified as needing further attention.
A number of substances have been identified as high priorities for action based on the information obtained through the categorization process. This includes substances:
that were found to meet all of the ecological categorization criteria,
including persistence, bioaccumulation potential and inherent toxicity to
aquatic organisms (PBiT), and that are known to be in commerce, or of commercial
interest, in Canada, and/or
that were found either to meet the categorization criteria for greatest
potential for human exposure or to present an intermediate potential for
exposure, and were identified as posing a high hazard to human health based
on available evidence on carcinogenicity, mutagenicity, developmental toxicity
or reproductive toxicity.
On December 8, 2006 the Government of Canada announced the Chemicals Management
Plan. The Plan includes a number of proactive measures to make sure that chemical
substances are managed properly.
A key element of the Chemicals Management Plan is the initiative known as the "Challenge" for about 200 high priority substances. This initiative was announced in a Notice published on December 9, 2006 in the Canada Gazette entitled: Notice of Intent to develop and implement measures to assess and manage the risks posed by certain substances to the health of Canadians and their environment. These 200 substances have been divided up into a number of smaller groups (batches) of substances. The Government of Canada is challenging industry to provide new information on the properties and uses of the substances in each batch sequentially.
Another key element of the Chemicals Management Plan is the Petroleum Sector Stream Approach. There are approximately 160 petroleum substances that are high priority, but were chosen to be addressed separately from the Challenge, under an approach specific to the oil and gas sector. These substances were identified by the Canadian Petroleum Products Institute (CPPI) and Health Canada as petroleum process stream mixtures (referred to as UVCBs). The high priority petroleum substances were separated from the Challenge because of the following considerations:
Large number of substances;
Substances that are primarily, if not exclusively, related to the petroleum
sector; and
Most are complex mixtures that may need to be considered differently from
discrete substances.
Environment Canada and Health Canada have developed a plan for the Petroleum Sector Stream Approach that includes data collection, assessment of the substances, and development of risk management instruments, if required. The first step is to gather all available information on high priority petroleum substances so that informed decisions are made and any potential risks that may be associated with these chemicals are appropriately managed.
As a starting point, an initial sorting or “triage” of the substances has been conducted, using a number of data sources including the March 2008 Notice with respect to certain high priority petroleum substances. From this information, the high priority petroleum substances have been divided into the following groups:
substances that are no longer in commerce, or are not related to the petroleum sector;
substances that do not leave petroleum sector facility sites (e.g. substances that are used as intermediates or feedstocks in on-site processes only) – “site-limited substances”;
substances that are transported from a petroleum sector facility to other industrial facilities (inside or outside of the petroleum sector), where they are consumed (e.g. as fuels or as feedstocks) – “industry-limited substances”; and
substances that are widely used by the public.
The July 25, 2009 notice requires information on one of the above groups: “industry-limited” substances. This group comprises 52 substances that are thought to be transported from a petroleum sector facility to other industrial facilities, where they are consumed as fuels or used as feedstocks. This information will support screening assessments and potential risk management for these substances, and includes details on the quantity of each substance that is transported to other industrial sectors, how it is transported, and to whom.
For further information on the Petroleum Sector Stream Approach, please consult the Government of Canada’s Chemical Substances Web site at www.chemicalsubstances.gc.ca(click on link to ‘The Petroleum Sector Stream Approach’).
Information for Completion of the March 8, 2008 Notice
Section 71 notices may be used to gather information for the purpose of assessing whether a substance is toxic or capable of becoming toxic, or for the purpose of assessing whether to control, or the manner in which to control, a substance.
The purpose of the current section 71 notice is to identify, for each of the substances covered under the notice:
the quantity ranges that are transported (from facilities in Canada that engage in petroleum refining and/or upgrading) by each mode of transportation to each recipient; and
the identity and location of the recipients.
2. Where Can I Get a Copy of the Notice?
The notice was published in Part 1 of the Canada Gazette, pursuant to paragraph 71(1)(b) of CEPA 1999 on July 25, 2009. Electronic copies of the notice can be found on the Internet site at the following addresses: www.ec.gc.ca/CEPARegistry/notices or www.chemicalsubstances.gc.ca(click on link to ‘The Petroleum Sector Stream Approach’).
3. How Should I Respond to the Notice?
If the notice applies to you, you are encouraged to provide the required information using the electronic format distributed by Environment Canada. If you do not have a copy of the electronic format, please contact Environment Canada at phone number 1-888-228-0530 or 819-956-9313, or at the following email address: DSL.SurveyCo@ec.gc.ca.
The data should be entered in the electronic format, saved on a compact disk and returned by mail. For the submission to be complete, you must also return an original signed copy of the “Identification and Declaration Form” (Section 3 of Schedule 3).
The electronic format is a straightforward way to report all information required. If you choose not to use the electronic format, please note that the information you are required to report is specified in Schedule 3 of the notice.
4. What Substances Are Included (Schedule 1)?
The table in Schedule 1 to the notice lists the substances covered by the
notice (listed by CAS RN1 and
substance name). However, in Section 13 of this guidance document, you
will also find a table that presents these substances along with a description
and some common synonyms for most of the substances. This additional
information is provided to assist you in identifying information related to
each substance at your facility, but may not present all potential descriptions
and synonyms that might exist for each substance. In case of discrepancy between
this document and the notice, the notice takes precedence.
Note that two substances listed in Schedule 1 were not included in the Section 71 Notice with respect to certain high priority petroleum substances, published in the Canada Gazette, Part I, on March 8, 2008. These substances were left off the March 2008 notice because they were initially thought to be widely-used products. However, additional research indicates that they may potentially be industry-limited substances, so they have been included in this notice in order to gain a complete understanding of their transportation and use.
CAS RN 68476-85-7 Petroleum gases, liquefied
CAS RN 68476-86-8 Petroleum gases, liquefied, sweetened
(The remaining substances in Schedule 1 were included in the March 8, 2008 notice.)

6.2 Facility Identification Form (Section 4)
The "Facility Identification Form" is provided for two reasons:
to obtain the identification and contact information of each facility for
which the responder is reporting; and
to assign an identification number to each facility for which the responder
is reporting.
The facility identification number (the left hand column in the facility identification
form), along with the facility name will be used to identify the specific facility
for which reported information pertains.
If you wish to have a single contact person for your entire submission, you can submit the same contact name for each facility. The electronic format will give you the option to indicate this, via a checkbox, and will automatically copy the contact name and information from the Identification and Declaration Form into the corresponding facility contact name and information boxes on the Facility Identification Form.
The “Facility Identification Form” has entries for five facilities. If you wish to report for more than five facilities, please contact Environment Canada at phone number 1-888-228-0530 or 819-956-9313, or at the following email address: DSL.SurveyCo@ec.gc.ca.
Information submitted on the “Facility Identification Form” for the Canadian Environmental Protection Act, 1999 section 71 Notice with respect to certain high priority petroleum substances, published in the Canada Gazette, Part I, on March 8, 2008, has been automatically entered into the “Facility Identification Form” for this notice. Please ensure that this information is still valid, and make any necessary changes.
6.3 Information on the Substances (Section 5)
a) What is the Facility Identifier?
Each facility to which a submission pertains will be numbered (starting at
number 1) on the facility identification form (Section 4 of Schedule 3). This
same number should appear on the page(s) where information on each substance
is provided for that particular facility. This will help to ensure that the
information is reported for the correct facility.
b) How do I report the activities performed at the facility
For each facility to which a submission pertains, the reporter must identify whether that facility performs petroleum refining, upgrading or both. See Section 1 of Schedule 3 of the notice (or Sections 5.1-5.3 of this document) for the definitions of petroleum refining and upgrading.
c), Manufacture, Acquire and Quantity Ranges
You are required to provide information for any substance listed on Schedule 1 of the notice that was transported from your facility in a total quantity greater than 100 kg for the 2006 calendar year.
“Transported from the facility” includes all shipments that leave the facility boundary. Examples include (but are not limited to):
shipments to customers (industrial users, distributors, etc.);
transfers to other industrial facilities, both inside or outside of your company; and
transfers to waste treatment or recycling facilities.
Please note that if your facility manufactured or acquired a substance, but it was consumed at the facility (e.g. as a fuel or a feedstock) or blended into a mixture (e.g. a product such as gasoline) that left the facility under a different CAS RN1, you are not required to report information for this substance.
For example, substance X is produced at your facility and then blended with several other streams to produce gasoline, which then leaves your facility. You should not report that substance X was transported from your facility (even if it is listed on the MSDS sheet of your gasoline product), because it did so only as part of a mixture that left the facility under a different CAS RN
d), Which recipients should I report?
You are required to provide information for any recipient that received a total quantity of greater than 100 kg of a given substance for the 2006 calendar year.
The “total quantity” refers to the sum of all shipments of the substance to the given recipient for the 2006 calendar year, not to the quantity contained in any one single shipment. For example, if you transported a small amount (less than 100 kg) of a given substance during the calendar year (e.g. to a laboratory for testing), you would not need to report that recipient of the substance. However, if you transported 50 kg of a given substance each day to Facility X, you should report Facility X as a recipient of this substance, because the total quantity for the 2006 calendar year is greater than 100 kg.
If you transported the substance to multiple facilities that are owned or operated by the same company (e.g. Company Y is one of your customers, and your facility transported greater than 100 kg of the same substance to both Company Y’s refinery in Montreal and Company Y’s distribution terminal in Halifax), provide information separately for each of the recipient facilities.
e), How do I report the recipients of the substances?
Enter the name (e.g. company or facility name), street address, the name of a contact person, telephone number, and email address (if any) for each recipient located in Canada that received a total quantity greater than 100 kg of the substance during the 2006 calendar year. When entering the recipient’s street address, please specify the city, province, and postal code.
For recipients located outside of Canada, enter the city, state (if applicable) and country of each recipient that received a total quantity greater than 100 kg of the substance during the 2006 calendar year. Please note that although you are not required to specify the name (e.g. company or facility name), street address, the name of a contact person, telephone number, and email address (if any) of these recipients, you may do so if you wish.
To enter multiple recipients for a substance, click on the “New Recipient” button for that substance: this will insert a blank row in which to enter the information. Add as many additional rows as required.
f), How do I report the quantity ranges transported from the facility to each recipient?
It is necessary to report the total quantity ranges transported to each recipient for the substances listed on Schedule 1 of the notice. Quantities must be estimated for the substance itself, and not the mixture, product or manufactured item in which it may be contained.
You are not required to report information for a given recipient of a substance if the total quantity transported to that recipient for the 2006 calendar year is less than or equal to 100 kg.
Quantity ranges must be reported by selecting the most appropriate of the quantity options given:
> 100, < 1,001 (value is greater than 100 but less than 1,001)
1,001, < 100,001 (value is greater than or equal to 1,001 but less than 100,001)
100,001, < 500,001 (value is greater than or equal to 100,001 but less than 500,001)
500,001, < 1,000,001 (value is greater than or equal to 500,001 but less than 1,000,001)
1,000,001, < 5,000,001 (value is greater than or equal to 1,000,001 but less than 5,000,001)
5,000,001, < 10,000,001 (value is greater than or equal to 5,000,001 but less than 10,000,001)
10,000,001, < 20,000,001 (value is greater than or equal to 10,000,001 but less than 20,000,001)
≥ 20,000,001 (value is greater than or equal to 20,000,001)
And by selecting one of the units given:
Kilograms
Tonnes (meaning metric tonnes, equal to 1000 kg)
Cubic Metres
Select the appropriate quantity range and units from the drop-down menus for each substance.
g) How do I report the approximate proportion (as a percentage) of the substance that was transported by each mode of transportation to each recipient?
The approximate proportion (as a percentage) for each substance must be specified for each applicable mode of transportation:
By pipeline
By rail, in non-pressurized containers (e.g. barrels, totes, or other small containers)
By rail, in pressurized containers (e.g. gas tanks or cylinders)
By rail, in pressurized tanker rail cars
By rail, in non-pressurized tanker rail cars
By road, in non-pressurized containers (e.g. barrels, totes, or other small containers)
By road, in pressurized containers (e.g. gas tanks or cylinders)
By road, in pressurized tanker trucks
By road, in non-pressurized tanker trucks
By ship, in non-pressurized containers (e.g. barrels, totes, or other small containers)
By ship, in pressurized containers (e.g. gas tanks or cylinders)
By ship, in a pressurized hold
By ship, in a non-pressurized hold
Select the approximate proportions (as percentages) from the drop-down menus for each mode of transportation. The approximate proportions can be given to the nearest 5%.
If the substance was transported from your facility by another mode of transportation, enter a brief description of the mode of transportation, and then indicate the approximate proportion (as a percentage).
If the substance was transported using a combination of methods in series, report the same approximate proportion (as a percentage) for each of the individual modes of transportation, even if this results in a total percentage of greater than 100%. For example, if the substance was always transported first by pipeline, and then transferred to ships for delivery, report that 100% of the substance was transported by pipeline, and that 100% of the substance was transported by ship. Also provide a brief description of the situation in the “Comments/Notes” column.
7. Information you may reasonably be expected to have access to
You are required to provide information that your company possesses or to which you may reasonably be expected to have access. For example, when importing a substance, mixture, product or manufactured item you may reasonably be expected to have access to the relevant Material Safety Data Sheet (MSDS). An MSDS is an important source of information on the composition of a purchased product. Note that the goal of the MSDS is to protect the health of the workers, not the environment. Therefore, an MSDS may not list all product ingredients on which the Minister of the Environment is requiring information under the notice. You are encouraged to contact your supplier for more detailed information on product composition.
Also, a company may reasonably be expected to have access to a parent company’s information regarding substances, mixtures, products or manufactured items. You are not required to conduct tests to comply with this notice.
As indicated in Section 3 of this document, you are encouraged to provide the information using the electronic format distributed by Environment Canada. The information should be saved on a compact disk. In order for the submission to be complete, you must also return an original signed copy of the “Identification and Declaration Form” (Section 3 of Schedule 3). This should be included with the compact disk, and mailed to Environment Canada.
Responses to the notice must be submitted to the Minister of the Environment, to the attention of the DSL Surveys Coordinator.
