EXPLANATORY NOTE

(This note is not part of the notice.)

In March 2004, the Government of Canada initiated a phased approach to the collection of greenhouse gas emissions and related information. This mandatory greenhouse gas reporting program was launched through the publication of the first Canada Gazette notice in March 2004, which set out basic reporting requirements. This notice is the thirteenth in a series of notices requiring the reporting of greenhouse gas emissions. This program is part of Canada's effort to develop, through a collaborative process with provinces and territories, a harmonized and efficient reporting system that will meet the information needs of all levels of government, provide Canadians with reliable and timely information on GHG emissions and support regulatory initiatives.

Minor changes have been made since the Notice with respect to reporting of greenhouse gases (GHGs) for 2015, consisting of minor clarifications of the definitions of “CO2 emissions from biomass decomposition” and “emissions.”

Reporting requirements on greenhouse gas emissions outlined in this notice are collected via Environment and Climate Change Canada's Single Window (ECCC SW) system that was launched in March 2010. The ECCC SW system currently collects data for Environment and Climate Change Canada's Greenhouse Gas Emissions Reporting Program and for British Columbia, Alberta, Ontario and New Brunswick, to support provincial GHG reporting regulations; the National Pollutant Release Inventory and its partners; and various other partner programs. The ECCC SW system is currently being considered for GHG reporting by other provinces. The use of a single system for reporting on GHG emissions helps to reduce the reporting burden on industry, and the overall cost to Government. The system requires industry to submit information that is common to multiple jurisdictions once, but also accommodates reporting requirements and thresholds that are jurisdiction-specific.

Compliance with the Act is mandatory and specific offences are established by subsections 272(1), 272.1(1) 272.2(1) 272.4(1) and 272.5(1) of the Act. Amendments to the fine scheme of the Act came into force on June 22, 2012. Subsections 272(2), (3) and (4) and 272.1(2), (3) and (4) of the Act set the penalties for persons who commit an offence under the Act. Offences include the offence of failing to comply with an obligation arising from the Act and the offence of providing false or misleading information. Penalties for the most serious offences include minimum fines and/or imprisonment. The amount of the fine can range from a minimum of $5,000 for an individual convicted following summary proceedings and/or to imprisonment for a term of up to six months, to a maximum of $6,000,000 for a large corporation convicted on indictment. The fine range doubles for second or subsequent offences and individuals may also be liable to a term of imprisonment of up to three years. Offences other than those in the category of “serious offences” are punishable by fines set at a maximum that ranges from $25,000 for an individual convicted following summary proceedings to $500,000 for a large corporation convicted on indictment. The maximum fines double for second or subsequent offences.

The current text of the Act, including the most recent amendments, is available on the Department of Justice Canada website: http://laws-lois.justice.gc.ca/eng/acts/C-15.31/.

The Act is enforced in accordance with the Compliance and Enforcement Policy for the Canadian Environmental Protection Act, 1999 available at www.ec.gc.ca/lcpe-cepa/default.asp?lang=En&n=5082BFBE-1. Suspected violations under the Act can be reported to the Enforcement Branch by email at ec.dale-enviroinfo-eed-enviroinfo.ec@canada.ca

DEPARTMENT OF ENVIRONMENT AND CLIMATE CHANGE

CANADIAN ENVIRONMENTAL PROTECTION ACT, 1999

Notice of intent to inform stakeholders of upcoming consultations on proposed changes to the Greenhouse Gas Reporting Program

Purpose of this notice

Environment and Climate Change Canada (ECCC) is proposing to conduct consultation activities in 2017 in relation to proposed changes to its facility Greenhouse Gas Emissions Reporting Program (GHGRP). Specifically, the Department is proposing to amend the reporting requirements under this program to gather additional information on facility GHG emissions.

These changes are part of the Department's efforts to better inform Canada's national greenhouse gas (GHG) inventory by directly incorporating facility-level emissions data to improve precision and consistency in national and provincial-level inventory estimates and to more accurately identify causes of changes in facility emissions. ECCC will work collaboratively with provinces and territories to further develop a harmonized and efficient reporting approach.

Stakeholders will be invited to provide comments on the expanded reporting requirements under the GHGRP. Information obtained during consultations will be used to tailor the expansion approach as well as inform the development of reporting requirements and future decisions on which sectors or activities should be included in the various phases of the expansion.

Background

In 2004, the Government of Canada initiated a mandatory GHG reporting program (GHGRP), which requires facilities to report their GHG emissions annually, through the publication of annual notices under section 46 of the Canadian Environmental Protection Act, 1999 (CEPA). The program currently targets operators of facilities emitting 50 kilotonnes (kt) or more in carbon dioxide equivalent (CO2eq.) units (mostly large industrial operations) and sets out basic reporting requirements. The GHGRP annually publishes the collected data in aggregated format, in keeping with the provisions set out in sections 49 to 53 of CEPA.

Lowering the reporting threshold

Starting with data to be reported in 2018 for the 2017 calendar year, ECCC is proposing to lower the reporting threshold for all facilities from 50 kt CO2 eq. to 10 kt CO2 eq. This change will lead to an enhanced understanding of industrial emission levels in Canada and provide improved coverage of certain industry sectors to support integration into the national GHG inventory through a bottom-up approach. It is also intended to better align the GHGRP with provincial GHG reporting programs in British Columbia, Ontario and Quebec.

Requirement for additional detailed data for selected sectors and activities

ECCC is also proposing to require facilities to report additional information, aligning requirements with provincial reporting regimes where possible. Currently, information is missing that would allow ECCC to separate the facility emissions by specific sources or activities, allocate the data to internationally agreed reporting categories, and describe emission quantifications as required by international reporting guidelines. The additional information will enable the integration of facility data directly into the national GHG inventory, and enhance consistency among provincial and federal GHG inventories.

This proposed expansion would occur in phases, each phase covering several industrial sectors at a time. For the first phase, ECCC is aiming to introduce the additional reporting requirements for a number of specified industries and activities in a notice to be published in Part I of the Canada Gazette in 2017 (i.e. starting with 2017 calendar year data to be reported in 2018). Notwithstanding the change in threshold, the current reporting requirements specified in the annual notice for all other types of facilities subject to these reporting requirements would be maintained.

Phase I:

Phases II and III:

To reduce the reporting burden, ECCC would seek, to the extent possible, to align the additional reporting requirements with those of the three provinces collecting facility data consistent with the requirements under the Western Climate Initiative, namely, British Columbia, Ontario and Quebec.

Reporting mechanism

Reporting requirements on GHG emissions would continue to be collected via ECCC's Single Window system. The ECCC Single Window system currently collects data for the GHGRP and for British Columbia, Alberta, Ontario and New Brunswick, to support provincial GHG reporting regulations; the National Pollutant Release Inventory and its partners; and various other partner programs. The use of a single system for reporting GHG emissions helps to reduce the reporting burden on industry, as well as the overall cost to governments.

Next steps

Consultation on the proposed changes is planned to begin in winter 2017. Further details will be released prior to the consultation period to provide information on the intended approach and the associated timelines.

As a first step in the engagement process, interested parties should submit their contact information to ECCC before January 9, 2017, so they may be included on the distribution list to receive updates on the proposed amendments to the program.

ANNEX

Summary of the draft screening assessment of the Alkyl Sulfates and α-Olefin Sulfonate Group

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a draft screening assessment of four substances referred to collectively as the Alkyl Sulfates and α-Olefin Sulfonate Group. The substances in this group were identified as priorities for assessment as they met categorization criteria under subsection 73(1) of CEPA. The Chemical Abstracts Service Registry Numbers (CAS RN (see footnote 4)), their Domestic Substances List names and their common names are listed in the table below.

Substances in the Alkyl Sulfates and α-Olefin Sulfonate Group
CAS RN Domestic Substances List name Common name
139-96-8 Sulfuric acid, monododecyl ester, compound with 2,2',2"-nitrilotris[ethanol] (1:1) Triethanolamine (TEA) lauryl sulfate
151-21-3 Sulfuric acid monododecyl ester sodium salt Sodium lauryl sulfate
2235-54-3 Sulfuric acid, monododecyl ester, ammonium salt Ammonium lauryl sulfate
68439-57-6 (see note a)) Sulfonic acids, C14-16-alkane hydroxy and C14-16-alkene, sodium salts Sodium C14-16 olefin sulfonate

All four substances in this group are anionic surfactants and do not occur naturally in the environment. They are primarily found in cleaning products (e.g. laundry, dishwashing, household products) and in other products used by consumers (e.g. shampoos, toothpastes, soaps, cosmetics, bubble bath products). Sodium lauryl sulfate can also be found in food packaging and is an approved food additive with a number of minor uses in limited foods. In 2011, all substances, with the exception of TEA lauryl sulfate, were manufactured in Canada in quantities ranging from 100 to 1 000 000 kg. In the same year, all four substances were imported into Canada in quantities ranging from 10 000 to 2 240 000 kg.

The ecological risks of the substances in the Alkyl Sulfates and α-Olefin Sulfonate Group were characterized using the ecological risk classification of organic substances (ERC). The ERC is a risk-based approach that employs multiple metrics for both hazard and exposure based on weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are established 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 based on their hazard and exposure profiles. The ERC identified the four substances in this assessment as having low-to-moderate potential to cause ecological harm.

Considering all available lines of evidence presented in this draft screening assessment, there is a low risk of harm to organisms and the broader integrity of the environment from TEA lauryl sulfate, sodium lauryl sulfate, ammonium lauryl sulfate and sodium C14-16 olefin sulfonate. It is proposed to conclude that TEA lauryl sulfate, sodium lauryl sulfate, ammonium lauryl sulfate and sodium C14-16 olefin sulfonate do not meet the criteria under paragraph 64(a) or (b) of CEPA as they are 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.

Exposure to the substances from drinking water and from use of cosmetics and cleaning products was estimated for the general population of Canada. Additionally, exposure to sodium lauryl sulfate was estimated based on its presence as a non-medicinal ingredient in nonprescription drugs and natural health products formulated as capsules/tablets and toothpastes.

TEA lauryl sulfate, sodium lauryl sulfate, and ammonium lauryl sulfate were grouped together on the basis of structural similarity and a read-across approach was used to characterize health effects. Sodium C14-16 olefin sulfonate was addressed separately. The liver is the target organ for systemic toxicity for alkyl sulfates with certain chain lengths, following oral administration. Liver effects, however, were not observed for sodium C14-16 olefin sulfonate. Developmental effects were observed for sodium C14-16 olefin sulfonate in some laboratory studies, but not in others.

The margins of exposure comparing critical effect levels and levels to which the general population may be exposed were considered adequate to address uncertainties in the health effects and exposure databases for TEA lauryl sulfate, sodium lauryl sulfate, ammonium lauryl sulfate and sodium C14-16 olefin sulfonate.

Based on the adequacy of the margins between critical effect levels and estimated exposure and on information presented in this draft screening assessment, it is proposed to conclude that TEA lauryl sulfate, sodium lauryl sulfate, ammonium lauryl sulfate and sodium C14-16 olefin sulfonate do not meet the criteria under paragraph 64(c) of CEPA as they are 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.

Proposed conclusion

It is proposed to conclude that TEA lauryl sulfate, sodium lauryl sulfate, ammonium lauryl sulfate and sodium C14-16 olefin sulfonate do not meet any of the criteria set out in section 64 of CEPA.

Considerations for follow up

While exposure of the environment to these substances is not of concern at current levels, these substances are associated with ecological effects of concern. Therefore, there may be concern for the environment if exposure were to increase. Follow-up activities to track changes in exposure or commercial use patterns are under consideration.

Stakeholders are encouraged to provide, during the 60-day public comment period on the draft screening assessment, any information pertaining to these substances that may help inform the choice of follow-up activity. This could include information on new or planned import, manufacture or use of this substance, or information not previously submitted to the ministers.

The draft screening assessment for these substances is available on the Government of Canada's Chemical Substances website (www.chemicalsubstances.gc.ca).

ANNEX

Summary of the draft screening assessment of 14 substituted diphenylamines

Pursuant to section 68 or 74 of the Canadian Environmental Protection Act, 1999 (CEPA) [Canada 1999], the Minister of the Environment and the Minister of Health have conducted a screening assessment of 14 substituted diphenylamines (SDPAs). The SDPAs were identified as priorities for action, as they met the categorization criteria under subsection 73(1) of CEPA or were considered a priority based on other human health concerns or on their potential use as alternatives for each other. One of these 14 SDPAs is benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene, known as BNST, which had previously been assessed during the Challenge initiative of the Chemicals Management Plan, and which is being reassessed based on new information obtained after the original assessment.

The Chemical Abstracts Service Registry Number (see footnote 5) (CAS RN) and Domestic Substance List (DSL) names of the 14 SDPAs are listed below. These include 7 discrete substances and 7 substances that are UVCBs (Unknown or Variable Composition, Complex Reaction Products, or Biological Materials). They are all diphenylamines with various degrees of phenyl or alkyl substitution and similar physical-chemical properties. The 7 substances that are UVCBs can also contain multiple chemical structures, a subset of which was selected as representative chemical structures which in some cases are also the same or analogous to the discrete SDPAs in this assessment.

SDPAs do not occur naturally in the environment. Based on the results of the mandatory and voluntary surveys for years 2006, 2011, 2012, and the Domestic Substances List Inventory Update for 2008, they are used in high quantities in Canada. In 2011, between 1 000 000 and 10 000 000 kg of SDPAs were imported into Canada, either as individual substances or as part of speciality chemical additive packages. In the same year, over 10 000 000 kg of SDPAs were also manufactured in Canada, the majority (over 90%) of which was exported. CAS RN 68921-45-9 (BNST) was not surveyed in 2011. For BNST, between 100 000 and 1 000 000 kg of this SDPA was imported into Canada in 2006, and between 1 000 000 and 10 000 000 kg was manufactured in 2006. The major uses of SDPAs in Canada are as antioxidants in automotive and industrial lubricants. SDPAs are also used as antioxidants/antidegradants in the manufacturing of plastics or polyurethane foams and rubber products, and are imported in polymers or polyols.

Environmental exposure to SDPAs was examined in multiple scenarios representing industrial activities and overall uses of SDPAs in Canada. The key activities examined were the manufacturing of SDPAs and the blending of lubricants, which are the major anticipated sources of release to the environment. Additional activities were examined, including SDPA uses in the plastics and rubber sectors, automotive and powertrain assembly lines, disposal of lubricants, and biosolids amendment to agricultural land. The scenarios focused on the total representative SDPA structures, to be inclusive of all SDPAs, given that SDPAs are potential replacements for each other, and changes in product formulations could occur with the total SDPA usage remaining relatively constant.

SDPAs are characterized by low water solubilities, low vapour pressures and high to very high octanol-water partition coefficients. Among the SDPA structures, those with the log Kow of less than 9 (i.e. monooctyl DPA, dimethyl distyrenated DPA, mononyl DPA, monostyrenated DPA, distyrenated DPA, dibutyl DPA, monobutyl DPA, monobutyl monooctyl DPA and monooctyl monostyrenated DPA) are considered to be bioavailable, while those with the log Kow exceeding 9 (i.e. dioctyl DPA, dinonyl DPA, diethyl monononyl DPA and diethyl dinonyl DPA) are not easily absorbed from the exposure medium or diet and thus are considered to have very low bioavailability and have limited bioaccumulation potential. Due to their lack of bioavailability, dioctyl DPA, dinonyl DPA, diethyl monononyl DPA, and diethyl-dinonyl DPA are considered to be of lower ecological hazard potential.

Due to their hydrophobic nature, SDPAs in the environment are primarily associated with sediments, suspended particulate matter and soil. They are considered to be persistent in the environment but are not expected to undergo long-range transport in water or air. Therefore, long-term exposures are expected to be near discharge areas and closer to emission sources.

Analyses revealed that the potential for adverse effects from SDPAs in the environment, including benthic species, aquatic species (fish), piscivorous mammals, and soil-dwelling organisms, is low. The determination of SDPA toxicity in aquatic species is affected by their low water solubilities, where effects are observed at exposure concentrations that surpass substance solubility limits. Low toxicity to soil- and sediment-dwelling organisms was also observed in SDPA exposure studies using the earthworm and freshwater midge as test species, respectively. Toxicity to the representative piscivorous species was evaluated using a read-across approach with rodent data, resulting in a toxicity reference value indicating potential for adverse effects (<10 mg/kg bw/day). To evaluate ecological effects of SDPAs, critical body burden (CBR) calculations were conducted for representative benthic species, aquatic species (fish), piscivorous mammals, and soil-dwelling organisms, and compared to the internal threshold levels of narcotic chemicals causing death. The CBR values were found to be below the threshold levels for both acute and chronic exposures, indicating minimal potential risk from exposure to SDPAs.

Considering all the lines of evidence presented in this draft screening assessment, there is currently low risk of harm to organisms and the broader integrity of the environment from the 14 SDPAs considered in this assessment. It is proposed to conclude that the 14 SDPAs considered in this assessment do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are 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.

The human health assessment considers all available lines of evidence on the 14 SDPA substances. For the human health assessment, exposure of the general population to SDPAs from environmental media is expected to be low, given the physical-chemical properties of these substances. Exposure from food is not expected. Exposure to the general population from the use of products available to consumers results primarily from foam cushioning and automotive lubricants via oral and dermal routes.

Available empirical data for 8 of the 14 substances in this grouping indicates that these substances are not likely genotoxic. Based on the empirical data available for this substance grouping, health effects following short-term oral exposure in animal studies include the liver and haematological and/or clinical chemistry parameters. The kidney is a target organ at higher doses.

Comparisons of estimates of exposure to the general population to SDPA from levels in environmental media and from use of consumer products with levels associated with adverse health effects are considered to be adequate to account for uncertainties in the health effects and exposure databases.

Based on the information presented in this draft screening assessment, it is proposed to conclude that the 14 SDPAs considered in this assessment do not meet the criteria under paragraph 64(c) of CEPA, as they are 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.

Proposed conclusion

It is proposed to conclude that the 14 SDPAs considered in this assessment do not meet any of the criteria set out in section 64 of CEPA. This proposed conclusion also applies to BNST, also considered among the 14 substances, which had previously been found to meet the criteria set out in section 64 of CEPA in a 2009 screening assessment conducted during the Challenge initiative of the Chemical Management Plan.

Considerations for follow-up

While exposure to SDPAs found in the environment is not of concern at current levels, some of the representative chemical structures of SDPAs are bioavailable and therefore may pose an environmental concern if exposure to these substances were to increase. Follow up activities to track changes in exposure or commercial use patterns are under consideration.

Stakeholders are encouraged to provide, during the 60-day public period on the draft screening assessment, any information pertaining to SDPAs that may help inform the choice of follow-up activity. This could include information on new or planned import, manufacture or use of the substances, or information not previously submitted to the Ministers.

The draft screening assessment for these substances is available on the Government of Canada's Chemical Substances website (www.chemicalsubstances.gc.ca). The BNST consultation document is available on the Government of Canada's CEPA Environmental Registry website on public consultations (https://ec.gc.ca/lcpe-cepa/eng/participation/default.cfm).

ANNEX

Summary of the science approach document

This science approach document (SciAD) presents a quantitative biomonitoring-based approach to identify substances of low concern for human health that were identified as priorities for assessment as they met categorization criteria under subsection 73(1) of CEPA and/or were considered a priority based on other human health concerns.

This biomonitoring-based approach considers available Canadian and U.S. human biomonitoring data based on the analysis of the substance or moiety in whole blood, serum and/or urine. When biomonitoring data indicate that general population exposure is below the biomonitoring guidance value, the substances or moieties are considered to be of low concern with respect to human health.

The application of this biomonitoring-based approach indicates that barium-containing substances, molybdenum-containing substances, silver-containing substances, thallium-containing substances and inorganic tin–containing substances would be of low concern with respect to human health at current levels of exposure.

An assessment of these substances conducted under section 74 of CEPA will be published at a later date.

A consultation period on this SciAD is being provided to the public, who will have an opportunity to provide comments and additional information in advance of this approach being applied in screening assessment reports. The publication of this scientific approach will assist the Government in addressing substances that are likely of low concern in an efficient and effective manner.

The science approach document is available on the Government of Canada's Chemical Substances website (www.chemicalsubstances.gc.ca).
