EXPLANATORY NOTE

(This explanatory note is not part of the notice of intent.)

Description

The notice of intent is an opportunity for the public to comment on the proposed amendments to the Domestic Substances List (DSL), pursuant to subsection 66(1) of the Canadian Environmental Protection Act, 1999 (CEPA), adding the letter “P” to the identifiers of 264 polymers, as the form of those polymers that were assessed met the reduced regulatory requirement (RRR) polymer criteria.

Background

The DSL provides an inventory of substances manufactured in or imported into Canada on a commercial scale. A substance not on the DSL is therefore a new substance in Canada. Under CEPA, no new substances can be imported into or manufactured in Canada above the prescribed thresholds before an assessment of their potential impacts on human health and the environment has been performed. Reporting requirements for new chemicals and polymers are set out in the New Substances Notification Regulations (Chemicals and Polymers) [the Regulations].

Substances on the DSL are not subject to notification under the Regulations; however, when a substance identifier on the DSL is followed by a regulatory flag (that is the letter “S,” “S prime” or “P”), this substance is subject to notification under certain circumstances.

The letter “P” after a substance identifier indicates that the substance assessed and added to the DSL met the RRR polymer criteria in the Regulations. Substances that meet the RRR polymer criteria are considered of low concern, which allows for fewer regulatory information requirements under the Regulations than for non-reduced regulatory requirement (non-RRR) polymers. Typically, a substance synthesized in a form that meets the RRR polymer criteria can also be synthesized in a form that does not meet these criteria.

The purpose of the letter “P” is to indicate that any person who intends to manufacture in or import into Canada the polymer in a form that does not meet the RRR polymer criteria in a quantity above prescribed thresholds must submit the information prescribed in the Regulations. Please consult section 4.7 of the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers) for help determining the applicable notification schedule.

Project scope

Environment and Climate Change Canada identified substances assessed as RRR polymers and added to the DSL prior to the introduction of the letter “P” in 2003.footnote 3Any form of these polymers that does not meet the RRR polymer criteria currently does not require notification. Therefore, it is proposed to add the letter “P” to the identifiers of these polymers to clarify that only the RRR forms of these polymers are on the DSL, as per their assessment, and not the non-RRR forms. The addition of the letter “P” would allow for the environmental and human health risk assessment of any form of these polymers that does not meet the RRR polymer criteria prior to their import or manufacture in Canada.

Next steps

Within 120 days of publication of the notice of intent, any person may submit comments on the proposed amendments, which will be taken into consideration during the development of the final order. The final order will be published in the Canada Gazette, Part II. Amendments to the DSL are not in force until the order is published in the Canada Gazette, Part II.

EXPLANATORY NOTE

(This explanatory note is not part of the notice of Intent.)

Description

The notice of intent (NOI) is an opportunity for the public to comment on the proposed amendments to the Domestic Substances List (DSL)footnote 2 to apply the Significant New Activity (SNAc) provisions of the Canadian Environmental Protection Act, 1999 (CEPA) to the substance piperazine, Chemical Abstracts Service [CAS] Registry No. 110-85-0, pursuant to subsection 87(3) of that Act.

Within 60 days of publication of the NOI, any person may submit comments to the Minister of the Environment (the Minister). These comments will be taken into consideration during the development of the Order amending the DSL to apply the SNAc provisions to this substance.

The DSL amendments are not in force until the Order is adopted by the Minister pursuant to subsection 87(3) of CEPA. The Order must be published in the Canada Gazette, Part II.

Applicability of the proposed Order

It is proposed that the Order amending the DSL require any person (individual or corporation) engaging in a significant new activity in relation to the substance to submit a Significant New Activity Notification (SNAN) containing all of the information prescribed in the Order at least 90 days before the day on which the significant new activity begins.

In order to address human health concerns, the Order would target the use of the substance in consumer products to which the Canada Consumer Product Safety Act applies. In addition, the Order would target the use in cosmetics as defined in section 2 of the Food and Drugs Act. Consumer products and cosmetics are potential sources of direct and significant human exposure to this substance.

For the manufacture of consumer products, notification would be required when

For the importation of the substance in consumer products, notification would be required when the total quantity of the substance thus imported by any person (individual or corporation) in a calendar year is greater than 10 kg, and

For the manufacture of cosmetics, notification would be required when the concentration of the substance in the cosmetic is equal to or greater than 0.1% by weight.

For the importation of the substance in cosmetics, notification would be required when the total quantity of the substance thus imported by any person (individual or corporation) in a calendar year is greater than 10 kg, and the concentration of the substance in the cosmetic is equal to or greater than 0.1% by weight.

Activities not subject to the proposed Order

Use of the substance in the manufacture of consumer products would not be subject to the proposed Order if

The importation of the substance in consumer products would not be subject to the proposed Order if the total quantity of the substance thus imported in a calendar year is 10 kg or less. For the importation of a total quantity of more than 10 kg of the substance in a calendar year, the proposed Order would not apply if

Use of the substance in the manufacture of cosmetics would not be subject to the proposed Order if the concentration of the substance in the cosmetic is less than 0.1% by weight.

The importation of the substance in cosmetics would not be subject to the proposed Order if the total quantity of the substance thus imported in a calendar year is 10 kg or less. For the importation of a total quantity of more than 10 kg of the substance in a calendar year, the proposed Order would not apply if the concentration of the substance in the cosmetic is less than 0.1% by weight.

The use or importation of piperazine as a research and development substance, a site-limited intermediate substance, or an export-only substance would not require the submission of a SNAN, as these activities are not expected to result in exposure to the general population in Canada. The terms “research and development substance” and “site-limited intermediate substance” are defined in subsection 1(1) of the New Substances Notification Regulations (Chemicals and Polymers). An export-only substance is a substance that is manufactured or imported in Canada and destined solely for foreign markets.

The proposed Order would not apply to uses of the substance that are regulated under the Acts of Parliament listed in Schedule 2 of CEPA, including the Pest Control Products Act, the Fertilizers Act and the Feeds Act. The proposed Order would also not apply to transient reaction intermediates, impurities, contaminants, or partially unreacted intermediates, or in some circumstances to items such as wastes, mixtures or manufactured items. However, it should be noted that individual components of a mixture may be subject to notification under the proposed Order. See subsection 81(6) and section 3 of CEPA, and section 3 of the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers) for additional information.

Information to be submitted

The NOI sets out the proposed requirements for information that would have to be provided to the Minister at least 90 days before the day on which the significant new activity begins. The Department of the Environment and the Department of Health will use the information submitted in the SNAN and other information to conduct environmental and human health assessments within 90 days after the complete information is received.

The information requirements in the proposed Order relate to general information in respect of the substance, details surrounding its use, and exposure information. Some of the proposed information requirements are set out in the New Substances Notification Regulations (Chemicals and Polymers).

Additional guidance on preparing a SNAN can be found in section 4 of the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers).

Compliance

When assessing whether or not a substance is subject to SNAc provisions,footnote 5 a person is expected to make use of information in their possession or to which they may reasonably be expected to have access. This means information in any of the notifier’s offices worldwide or other locations where the notifier can reasonably have access to the information. For example, manufacturers are expected to have access to their formulations, while importers or users of a substance, mixture, or product are expected to have access to import records, usage information, and the relevant Safety Data Sheet (SDS).

Although an SDS is an important source of information on the composition of a purchased product, it should be noted that the goal of the SDS is to protect the health of workers in the workplace from specific hazards of chemical products. Therefore, an SDS may not list all product ingredients that may be subject to an order due to human health or environmental concerns. Any person requiring more detailed information on product composition is encouraged to contact their supplier.

Where a person involved in activities with the substance obtains information that reasonably supports the conclusion that the substance is toxic or is capable of becoming toxic, the person is obligated, under section 70 of CEPA, to provide that information to the Minister without delay.

Under section 87.1 of CEPA, any person who transfers the physical possession or control of a substance subject to an order shall notify all persons to whom the physical possession or control is transferred of the obligation to comply with the order, including the obligation to notify the Minister of any significant new activity and to provide all the required information outlined above.

In cases where a person receives physical possession or control of a substance from another person, they may not be required to submit a SNAN, under certain conditions, if the activities were covered by the SNAN submitted by the supplier on behalf of its clients.

A pre-notification consultation (PNC) is available for notifiers who wish to consult during the planning or preparation of their SNAN to discuss any questions or concerns they have about the prescribed information and test plans.

Where a person has questions concerning their obligations to comply with a notice or order, believes they may be out of compliance, or would like to request a PNC, they are encouraged to contact the Substances Management Information Line.footnote 6

The CEPA is enforced in accordance with the publicly available Compliance and Enforcement Policy for the Canadian Environmental Protection Act, 1999 (CEPA, 1999). In instances of non-compliance, consideration is given to the following factors, when deciding which enforcement measure to take: nature of the alleged violation, effectiveness in achieving compliance with CEPA and its regulations and consistency in enforcement.

ANNEX

Summary of the assessment of piperazine

Pursuant to section 68 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted an assessment of piperazine. The Chemical Abstracts Service Registry Number (CAS RN) for piperazine is 110-85-0.

Piperazine does not occur naturally in the environment. According to information submitted in response to a CEPA section 71 survey, the substance was not manufactured above the 100 kg reporting threshold for the 2008 reporting year. However, piperazine was imported into Canada between 10 000 kg and 100 000 kg for commercial use in paints and coatings, and as a chemical intermediate in industrial settings, including use in carbon capture and storage systems. Information obtained from other programs within Health Canada, as well as product safety data sheets, identified additional uses in Canada, including as a medicinal ingredient in some veterinary antiparasitic drugs and as a co-monomer in epoxy adhesives. It is possibly used as a flavouring agent in foods sold in Canada.

The ecological risk of piperazine was characterized using the ecological risk classification of organic substances (ERC), which is a risk-based approach that employs multiple metrics for both hazard and exposure, with weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are based principally on metrics regarding mode of toxic action, chemical reactivity, food web–derived internal toxicity thresholds, bioavailability, and chemical and biological activity. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is used to assign a low, moderate or high level of potential concern for substances on the basis of their hazard and exposure profiles. Based on the outcome of the ERC analysis, piperazine is considered unlikely to be causing ecological harm.

Considering all available lines of evidence presented in this assessment, there is a low risk of harm to the environment from piperazine. It is concluded that piperazine does not meet the criteria under paragraph 64(a) or (b) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.

Neurological effects were identified by the Organisation for Economic Co-operation and Development and in the European Union Risk Assessment Report as the critical health effect, based on clinical reports and studies of humans receiving piperazine administered as an antiparasitic drug. Piperazine is also classified by the European Chemicals Agency as a reproductive toxicant and a respiratory sensitizer.

Piperazine was not detected in a Canadian indoor air study and no other monitoring data of piperazine in the environment were identified. Piperazine is expected to partition to water if released to the environment and is not expected to be stable in air. Consequently, estimates of piperazine exposure to Canadians from environmental media were calculated based on potential wide-disperse releases to surface water and point source releases to air. Piperazine may be released to the environment (i.e. air and water) when used in industrial applications, including use in carbon capture and storage systems (also referred to as gas scrubbers). Based on a comparison of the estimates of exposure to piperazine from environmental media and levels at which critical effects are observed, margins are considered to be adequate to address uncertainties in the health effects and exposure databases.

Based on the per capita intake estimate for the population of the United States from the Joint FAO/WHO (Food and Agriculture Organization of the United Nations/World Health Organization) Expert Committee on Food Additives (JECFA), exposure to Canadians from piperazine and its use as a food flavouring agent is considered negligible and the risk to human health is considered to be low.

Exposures to piperazine for the general population of Canada can occur from its use in epoxy adhesive products available to consumers. Based on a comparison of estimated dermal and inhalation exposures to piperazine with levels at which critical effects are observed, margins are considered adequate to address uncertainties in the health effects and exposure databases.

The human health assessment took into consideration those groups of individuals within the Canadian population who, due to greater susceptibility or greater exposure, may be more vulnerable to experiencing adverse health effects. These subpopulations were taken into account in the risk assessment outcomes of the piperazine screening assessment. In addition, people with the potential for elevated exposure who live near potential releases of piperazine from its use in industrial gas scrubbers were considered in the screening assessment.

Considering all the information presented in this assessment, it is concluded that piperazine does not meet the criteria under paragraph 64(c) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Overall conclusion

It is therefore concluded that piperazine does not meet any of the criteria set out in section 64 of CEPA.

Consideration for follow-up

Because piperazine is listed on the Domestic Substances List (DSL), its import and manufacture in Canada are not subject to notification under the New Substances Notification Regulations (Chemicals and Polymers) under subsection 81(1) of CEPA. Since piperazine is considered to have human health effects of concern, there is a suspicion that new activities that have not been identified or assessed could lead to this substance meeting the criteria set out in section 64 of CEPA. Therefore, the Government of Canada intends to amend the DSL, under subsection 87(3) of the Act, to indicate that the significant new activity (SNAc) provisions under subsection 81(3) of the Act apply with respect to this substance.

A significant new activity can include an activity that has not been conducted with the substance in the past, or an existing one with a different quantity or in different circumstances that could affect the exposure pattern of the substance. The SNAc provisions trigger an obligation for a person (individual or corporation) to provide information about a substance when a person proposes to use the substance in a significant new activity. The ministers will assess the information provided by the notifier and other information available to them to determine whether the substance, if used in the proposed new activity, could pose a risk to the environment or human health, and, if so, whether risk management is required.

The assessment for this substance is available on the Canada.ca (Chemical substances) website.
