Response to Comments and Notices of Objections Received on Proposed Agreements Respecting Canada-Wide Standards for Particulate Matter and Ozone, Mercury, and Benzene-Phase 1

Whereas on February 5, 2000, the Minister of the Environment published in Part I of the Canada Gazette, pursuant to subsection 9(2) of the Canadian Environmental Protection Act, 1999, the proposed Agreements respecting Canada-Wide Standards for Particulate Matter and Ozone, Mercury, and Benzene Phase 1, being developed by the Canadian Council of Ministers of the Environment under the framework of the Canada-Wide Accord on Environmental Harmonization and the Canada-Wide Environmental Standards Sub-Agreement,

Whereas the Minister of the Environment has been filed with comments and notices of objection in respect thereto,

Now therefore, pursuant to subsection 9(4) of the Act, the Minister of the Environment hereby publishes the attached report that summarizes how any comments or notices of objection were dealt with.

DAVID ANDERSON
Minister of the Environment

Introduction

In accordance with subsection 9(2) of the Canadian Environmental Protection Act, 1999, on February 5, 2000, the Minister of the Environment published proposed agreements with the provincial and territorial governments (except Quebec) respecting Canada-wide Standards (CWSs) for particulate matter (PM), ozone, mercury, and benzene phase 1 for a 60-day comment period. The agreements were developed by the Canadian Council of Ministers of the Environment (CCME) under the framework of the Canada-Wide Accord on Environmental Harmonization and the Canada-Wide Environmental Standards Sub-Agreement. CCME Ministers intend to sign the agreements in June 2000.

In accordance with subsection 9(4) of the Act, this report summarizes how the comments and notices of objection were dealt with.

Summary of Submissions

A total of nine submissions were received, including two notices of objection. Two submissions were received from public health authorities, six from certain industry representatives, and one from government.

Comments on the benzene CWS generally supported phase 1 and the need for future action on benzene. The only comment on the mercury CWS stressed the need to keep stakeholders involved in the development of future standards.

Most of the submissions dealt with the proposed CWSs on particulate matter and ozone. The submissions from health authorities supported earlier and stronger action on PM and ozone, while those from industry expressed concern about uncertainties in the analysis and suggested that the CWS be delayed or qualified as interim.

Notices of Objection

Under subsection 333(2) of the Act, where a person files a notice of objection in respect of an agreement made under section 9, the Minister may establish a board of review to inquire into the matter. One of the notices of objection indicated that the proposed standards are technically unachievable, are not supported by economic analysis, and are not supported by current scientific knowledge. The second notice of objection was critical of the consultation process.

Upon careful consideration of the comments, the Minister of the Environment concluded that a board of review is not necessary in this instance. This decision is based on the following considerations:

— The available evidence indicates that the CWSs are achievable, technically feasible and economically viable, and will provide significant human health benefits. Governments are committed to conducting further scientific, technical and economic analyses, and to review the standards.

— The comments are consistent with previously stated positions expressed during the consultations and were considered by governments during the development of the proposed CWSs.

— The CWSs were developed with extensive involvement of stakeholders. Improvements to the consultative process can be made without the need for a board of review.

— A board of review would be most unlikely to reveal additional information that would be relevant to the decisions to be made as the notices of objection did not bring forward considerations either scientific or otherwise that had not previously been considered.

Response to Comments

The submissions on the PM and ozone CWSs contained seven main themes. A description of these themes and Environment Canada's response are outlined below.

Timeframe for Achieving the Proposed CWS for Ozone

Public health authorities indicated that the proposed date for achieving the CWS for ozone (2015) was too long a period and would result in unnecessary adverse health impacts. Industry stakeholders indicated that the other options being considered (2010 or 2012) are too early and that the time for implementation is inadequate.

Response: Given the significant health impacts of ozone, Environment Canada is intent on achieving the CWS for ozone at the earliest possible date. Environment Canada also recognizes the need to consider the full range of impacts and technological considerations associated with the potential dates when developing specific actions to achieve the standards.

Level of the Proposed CWS for Ozone

Public health authorities indicated that the CWS for ozone should be more stringent. Some industry stakeholders indicated that decisions have been based on inadequate data.

Response: Environment Canada is satisfied that the proposed CWS level for ozone improves upon the current national ambient air quality objective and is a challenging target yet achievable within the proposed timeframes. Governments are committed to conducting further scientific, technical and economic analyses, and to revise the standards in the future as appropriate.

Level of the Proposed CWS for PM2.5

Public health authorities indicated that the level of the proposed PM2.5 CWS should be more stringent. Industry suggested that setting a standard for PM was premature or at a minimum, that the standard for PM should be qualified as interim.

Response: There is ample evidence that PM causes serious human health and environmental impacts and that action is needed now. Environment Canada is satisfied that the level of the proposed PM2.5 CWS is a challenging target yet achievable. Governments are committed to conducting further scientific, technical and economic analyses, and to revise the standards in the future as appropriate.

Standard for Coarse Particulate Matter

Public health authorities supported setting a standard for coarse PM in addition to the standard for fine PM.

Response: Environment Canada agrees that the coarser fraction needs to be addressed. However, Environment Canada is also satisfied that the finer particles pose a greater threat and need to be the first priority for action. Governments are exploring the best approach for coarse particulate matter, one approach would be to develop a standard for PM10-2.5 rather than having two standards (PM2.5 and PM10) which overlap.

Uncertainty in the Analysis

Certain industry stakeholders indicated that decisions have been based on inadequate data and analysis. Some suggested that the CWS should be delayed to allow for completion of the Expert Panel review of costs and benefits, and other studies taking place in the United States.

Response: There is ample evidence that these substances cause serious human health and environmental impacts. While there may be some uncertainties in the science and other impacts with respect to PM, and to a lesser extent with ozone, governments are satisfied that there is sufficient evidence that requires action to be taken now. Environment Canada believes that these standards are achievable both technically and otherwise. Governments are committed to improving the information base and integrating emerging information and analyses in future reviews of the CWSs, as well as the development of specific actions. The review will draw upon results of research in the United States and elsewhere, as well as the work of the Expert Panel.

Background Concentrations and Transboundary Contributions

Certain industry stakeholders noted that background concentrations of PM and ozone in some areas of Canada are equivalent or greater than the proposed CWSs and that transboundary sources are major contributors to the problem, particularly in Ontario. They noted that in many areas of Canada, it will not be possible to meet the proposed standards.

Response: The CWS provides for the identification of communities influenced by background or natural events and transboundary pollution. Such influences will be taken into account when determining attainment of the CWS. Governments believe that these provisions are the best way to take into account different circumstances while preserving the benefits of a stronger standard for the country as a whole. Environment Canada is also committed to aggressive negotiations with the United States to reduce transboundary pollution.

The Consultation Process

Some industry stakeholders indicated that the consultations were inadequate. In particular, there was concern that comments were not dealt with satisfactorily and that feedback was not sufficient.

Response: Environment Canada and CCME are committed to meaningful involvement of stakeholders. Indeed, the CWS development process involved extensive participation by all stakeholders, many of whom indicated that the consultative process was successful as improvements to the process were made along the way. As in all multi-stakeholder consultations, not all views can be accommodated and Ministers may choose to adopt all, some or none of the recommendations submitted in the consultations. Environment Canada is committed to considering these suggestions in future work on all Canada-wide Standards.

Notice therefore is hereby given that the Ministers of the Environment and of Health intend to recommend to Her Excellency the Governor in Council that acetaldehyde be added to the List of Toxic Substances in Schedule 1 to the Canadian Environmental Protection Act, 1999.

Notice furthermore is hereby given that consultations will be held on the development of a regulation or instrument respecting preventive or control action in relation to acetaldehyde.

Annex

Summary of the Report of the Assessment of the substance acetaldehyde specified on the Priority Substances List

In Canada, the major use of acetaldehyde is in the production of pentaerythritol for use in alkyd resin production, fatty acid esters (synthetic lubricants), rosin and tall oil esters, and other smaller-volume applications. The Canadian domestic demand for acetaldehyde was under 10 000 tonnes in 1996.

Acetaldehyde enters the Canadian environment from natural sources (including forest and bush fires), from human sources such as fuel combustion and industrial on-site releases, and through secondary formation as a result of the atmospheric oxidation of natural and anthropogenic organic compounds. Although there are no quantitative estimates of releases from natural and secondary sources in Canada, it is believed that these sources are very large. However, the highest concentrations measured in the environment are present near anthropogenic sources. On-road motor vehicles are the largest human source of acetaldehyde emissions to the Canadian environment, releasing about 3 290 tonnes per year into the air. The amount of acetaldehyde estimated to have been released into the Canadian environment from industrial processes in 1996 was 478 tonnes.

When acetaldehyde is released to or formed in air, most will undergo various degradation processes in air, and a very small amount will move into water. When acetaldehyde is released into water, it degrades there and does not move into other media. Acetaldehyde does not persist in the environment, but its continuous release and formation result in chronic exposure of biota near sources of release or formation.

Extensive recent data are available on concentrations of acetaldehyde in urban, suburban and rural air in Canada, and data are available on concentrations in air at the largest industrial emitter of acetaldehyde in Canada. Limited data are available on concentrations in surface water in four rivers and in groundwater at the industrial site that is the largest single emitter of acetaldehyde. Environmental toxicity data are available for a range of terrestrial and aquatic organisms, although mostly only for acute exposure. Based on the highest concentrations measured in air and in surface water and groundwater in Canada and on the Estimated No-Effects Values derived from experimental data for terrestrial and aquatic biota, it is unlikely that organisms are exposed to harmful levels of acetaldehyde in the Canadian ambient environment.

Acetaldehyde is not involved in the depletion of stratospheric ozone or in climate change. Because of its photo-reactivity and its moderate concentrations in the air in Canadian cities, acetaldehyde plays a role, along with other reactive volatile organic chemicals in air, in the photochemical formation of ground-level ozone.

The focus of the human health assessment is airborne exposure. Based on short-term and long-term inhalation studies conducted in experimental animals, the upper respiratory tract is the principal target site for effects of inhaled acetaldehyde. In short-term studies, acetaldehyde causes degenerative non-neoplastic effects. Although it is genotoxic both in vitro and in vivo, tumours have been observed following inhalation only at concentrations that have produced significant cytotoxicity, and it is likely that both the genotoxicity and irritancy of acetaldehyde play a role in its carcinogenicity.

Therefore, a Tolerable Concentration (based on a benchmark concentration or an effect level) and a Tumorigenic Concentration have been derived for this substance.

Based on the information available, it is concluded that acetaldehyde is not entering the environment in a quantity or concentration or under conditions that have or may have a harmful effect on the environment or its biological diversity. Acetaldehyde may enter the environment in a quantity or concentration or under conditions that constitute or may constitute a danger to the environment on which life depends or a danger to human life or health in Canada. Therefore, acetaldehyde is considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Since acetaldehyde contributes to the formation of ground-level ozone, it is recommended that key sources of acetaldehyde be addressed as part of management plans for volatile organic chemicals associated with the formation of ground-level ozone.

Based on the comparison of the carcinogenic potency of acetaldehyde with estimates of population exposure, the priority for investigation of options to reduce exposure of the general population in the ambient environment is considered to be moderate only. Additional work on characterization of exposure of populations in the vicinity of industrial point sources and of sources in indoor air may be warranted.

Whereas a summary of a report of the assessment of the substance acrolein specified on the Priority Substances List is annexed hereby,

Notice therefore is hereby given that the Ministers of the Environment and of Health intend to recommend to Her Excellency the Governor in Council that acrolein be added to the List of Toxic Substances in Schedule 1 to the Canadian Environmental Protection Act, 1999.

Annex

Summary of the Report of the Assessment of the substance acrolein specified on the Priority Substances List

Acrolein is not commercially produced in Canada. It is imported from the United States for use mainly as an aquatic herbicide in irrigation canals and as a microbiocide in produced water during oil explorations. These uses are regulated under the Pest Control Products Act and Regulations. An estimated minimum of 218 tonnes of acrolein is released yearly to the atmosphere from anthropogenic sources involving the combustion of organic matter (i.e., predominantly as a component of vehicle exhaust) or the forest industry. Unquantified amounts are also released from natural sources and the photooxidation of organic pollutants in air. No releases of "non-pesticidal" acrolein to water, sediments or soils in Canada have been identified.

Acrolein is unlikely to be transported over long distances because of its high reactivity and estimated short half-lives in air and water. It is also unlikely to partition from these compartments to soil or sediments. Acrolein is rapidly metabolized by organisms and does not bioaccumulate. The highest environmental concentrations of acrolein not directly released during its application as a pesticide in Canada have been measured in air from urban areas. With the exception of samples taken in the vicinity of pesticidal application, acrolein has not been detected in water, sediment or soil in Canada.

Acute and chronic data on toxicity are available for aquatic organisms and laboratory animals. Only acute data were identified for terrestrial crop plants. Terrestrial organisms appear less sensitive to acrolein than aquatic organisms. Known concentrations of acrolein in the Canadian atmosphere are less than the threshold for adverse effects estimated for terrestrial organisms. Exposure of other organisms to non-pesticidal acrolein is considered unlikely, since no sources or detectable concentrations of acrolein have been identified in other compartments. Acrolein is not involved in stratospheric ozone depletion and is not an important contributor to climate change or photochemical smog formation.

Based upon studies conducted primarily with laboratory animals, adverse health effects associated with exposure to acrolein are mostly confined to the tissue of first contact (i.e., the respiratory and gastrointestinal tracts after inhalation and ingestion, respectively) and are concentration related. Hence, for comparison with Tolerable Concentrations for both inhalation and ingestion, exposures via these routes have been assessed separately. Tolerable Concentrations are the concentrations to which it is believed that a person may be exposed continuously without deleterious effect.

Available information is considered insufficient to characterize exposure of Canadians to acrolein via ingestion. However, the range of concentrations measured in food in other countries (although highly dependent upon such factors as method of cooking) is within the range of a provisional Tolerable Concentration for ingestion that is protective for site-of-contact effects.

Probabilistic estimates of the distribution of time-weighted 24-hour concentrations of acrolein in air indicate that between 5 percent and 10 percent of the general population would be expected to be exposed to at least 5 &microg/m3. This is greater than the Tolerable Concentration for inhalation derived on the basis of site-of-contact effects in animal species.

Based on the information available, it is concluded that acrolein is not entering the environment in a quantity or concentration or under conditions that have or that 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. It is concluded that acrolein is entering the environment in a quantity or concentration or under conditions that constitute a danger in Canada to human life or health. Therefore, acrolein is considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Indoor air is an important source of exposure, although the relative contribution of various sources therein is unknown. Better characterization of the significance of sources in indoor air and investigation of the potential to reduce emissions or exposure are also desirable.

While for the general population, the contribution of ambient air to overall exposure to inhaled acrolein is expected to be small, compared with the contribution from indoor air, ambient air may be an important source of exposure via inhalation for populations residing in the vicinity of locations heavily impacted by vehicular exhaust. Additional characterization of the contribution of motor vehicle exhaust to air in Canada and investigation of the potential to reduce emissions from this source are also recommended.

In view of the sensitivity of some aquatic organisms, it is also recommended that the use of acrolein to control aquatic weeds be reviewed by appropriate authorities under the Pest Control Products Act in light of this assessment and other relevant considerations.

Whereas a summary of a report of the assessment of the substance acrylonitrile specified on the Priority Substances List is annexed hereby,

Notice therefore is hereby given that the Ministers of the Environment and of Health intend to recommend to Her Excellency the Governor in Council that acrylonitrile be added to the List of Toxic Substances in Schedule 1 to the Canadian Environmental Protection Act, 1999.

Annex

Summary of the Report of the Assessment of the substance acrylonitrile specified on the Priority Substances List

Acrylonitrile is not produced in Canada but is imported and used to produce nitrile-butadiene rubber, acrylonitrile-butadiene-styrene (ABS) polymers and styrene-acrylonitrile (SAN) polymers. In 1994, 7 600 tonnes of acrylonitrile were used in Canada, all of which was imported from the United States. It was projected that 8 300 tonnes would be used in 1997. There are no known natural sources of acrylonitrile.

The atmosphere and the freshwater aquatic environment receive 97.3 percent and 2.7 percent of the releases of acrylonitrile, respectively. The releases are almost exclusively (97.4 percent) from the organic chemical manufacturing industry — namely, the chemicals and chemical products industry and the plastics industry — and occur in southern Ontario and southern Quebec. Municipal water treatment facilities may release small quantities of acrylonitrile to air via sludge incineration or to water via use of acrylonitrile polymers as conditioners.

Acrylonitrile is distributed largely to the environmental compartment to which it is released, where reaction and advection are the major removal mechanisms. Its movement from the atmosphere or water to soil, sediment or biota is limited.

In general, concentrations of acrylonitrile in air in Canada are below the detection limit. Predicted maximum levels (near a chemical industry processing plant in Sarnia, Ontario) are less than the Estimated No-Effects Value (ENEV) for the most sensitive terrestrial organism. Significant changes over the past 10 years to the treatment of industrial wastewaters have decreased the concentration in effluents discharged to the environment to below 4.2 µg/L. This is less than the ENEV for the most sensitive aquatic organism.

Because of its reactivity in the atmosphere, acrylonitrile's potential contribution to photochemical ozone (and also smog) creation is moderate; however, quantities and concentrations available for reaction (18.75 tonnes in Canada in 1996) make the contribution very low relative to those of other substances. The absence of chlorine and bromine atoms in the acrylonitrile molecule means that its potential contributions to stratospheric ozone depletion and climate change are both negligible.

Although limited, available data are consistent with air being the principal medium of exposure of the general population to acrylonitrile; intake from other media is likely to be negligible in comparison. The focus of the human health risk characterization is populations exposed through air in the vicinity of industrial sources.

Based on studies in animals, cancer is considered the critical endpoint for effects of acrylonitrile on human health. A range of tumours in rats — including those of the central nervous system (brain and/or spinal cord), ear canal, gastrointestinal tract and mammary glands — has been consistently observed following both ingestion and inhalation. While increases in cancer have not been observed in available epidemiological studies, their power is insufficient to rule out increases in particularly rare tumours. Available data are insufficient to support a consensus view on a plausible mode of action for induction of tumours by acrylonitrile by other than direct interaction with genetic material and as a result, there is considered to be a probability of harm at any level of exposure.

Based on the information available, it is concluded that acrylonitrile is not entering the environment in a quantity or concentration or under conditions that have or that 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. It is concluded that acrylonitrile is 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. Therefore, acrylonitrile is considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Based on comparison of worst-case estimates of exposure in air in the vicinity of industrial sources with the tumorigenic potency, it is recommended that options to reduce exposure in the vicinity of industrial point sources be investigated. It is also recommended that there be additional investigation of the magnitude of exposure of populations in the vicinity of industrial point sources as a basis for risk management.

Summary of the Report of the Assessment of the substance Carbon Disulfide specified on the Priority Substances List

Carbon disulfide is commercially produced in Canada, with annual production of about 3 kilotonnes. It is mainly used as a precursor in the manufacture of xanthates which are used as flotation agents in mineral refinery processes. Releases into the environment from human activities occur primarily as a result of its production as a by-product in oil and gas processing in Canada. Additional industrial releases result from its use in the chemical industry and tire manufacturing. Virtually all anthropogenic and natural releases are to air. Carbon disulfide is also produced naturally by several types of soil, sediment and aquatic microorganisms, vegetation, forest and grass fires and volcanoes. Worldwide, at least 40 percent and possibly as much as 80 percent of releases are a result of natural or biogenic activity.

Carbon disulfide is ubiquitous throughout the environment. It has been detected in air, water, sediment and soil; however, it is found primarily in air. The highest concentrations of carbon disulfide in Canadian air have been measured near industrial sources, in particular near natural gas processing plants and sites with sulfur-containing natural gas flares. Carbon disulfide is removed from the air primarily by reaction with hydroxyl radicals, resulting in a half-life of one to two weeks. This half-life in air makes it a candidate for long-range transport; however, it is rapidly diluted to natural background levels. Carbon disulfide is rapidly metabolized by organisms and does not bioconcentrate or biomagnify.

As carbon disulfide is mainly released to and detected in air, this is a critical compartment in the assessment of risk to the environment. In situations where carbon disulfide-containing effluents are released to surface waters, biota in water may be exposed. Selected assessment endpoints are, therefore, terrestrial plants and animals and freshwater organisms. Carbon disulfide is of moderate to low toxicity to aquatic biota.

Based on concentrations measured in air and surface water in Canada and on the Estimated No-Effects Values derived from experimental data for terrestrial and aquatic biota, it is unlikely that organisms are exposed to harmful levels of carbon disulfide in the Canadian ambient environment.

Carbon disulfide is not likely to contribute significantly to depletion of stratospheric ozone, ground-level ozone formation or climate change.

Available data upon which to base estimates of human exposure to carbon disulfide in Canada are extremely limited; however, air appears to be the major route of exposure for members of the general population. Airborne exposures are estimated to be elevated for populations in the vicinity of industrial point sources in Canada. Based on the results of epidemiological studies of workers exposed to carbon disulfide and supporting data from experiments conducted on animals, the nervous system appears to be the critical target for carbon disulfide-induced toxicity, manifested most often as reduced conduction velocity in the peripheral nerves and impaired performance in psychomotor testing. Other effects for which there is considerable weight of evidence in humans exposed to carbon disulfide include alterations in serum lipids and blood pressure that are associated with increased risk of heart disease, damage to the blood vessels of the retina and (with higher exposures) increased mortality from heart disease. The estimated mean airborne exposure to carbon disulfide for the general population, and for populations in the vicinity of point sources, is considerably less than a Tolerable Concentration derived on the basis of a benchmark concentration for reduced peroneal motor nerve conduction velocity in a population of viscose rayon workers exposed to carbon disulfide. A Tolerable Concentration is the level to which it is believed a person may be exposed daily over a lifetime without deleterious effect.

Based on the information available, it is concluded that carbon disulfide 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, that constitute or may constitute a danger to the environment on which life depends, or that constitute or may constitute a danger in Canada to human life or health. Therefore, carbon disulfide is not considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

The evaluation of options under CEPA 1999 to reduce exposure is not considered to be a priority at this time. However, this is based on current use patterns; thus, future releases of this compound should continue to be monitored to ensure that exposure does not increase to any significant extent.

Summary of the Report of the Assessment of the substance Respirable Particulate Matter Less than or Equal to 10 Microns specified on the Priority Substances List

Particulate matter (PM) refers in this assessment to particles of less than or equal to 10 µm mass median aerodynamic diameter (PM10). PM10 generally includes a fine fraction of particles 2.5 µm or less (PM2.5) and a coarse fraction of particles larger than 2.5 µm (PM10-2.5). Particulate matter can be emitted directly into the atmosphere or formed secondarily from precursor gases as a result of physical and chemical transformations. Particulate matter may include a broad range of chemical species, such as elemental carbon and organic carbon compounds, oxides of silicon, aluminum and iron, trace metals, sulphates, nitrates and ammonia.

Particulate matter is ubiquitous, being emitted from both natural and anthropogenic sources. The fine fraction of particulate matter and its precursor gases originate typically from combustion processes — motor vehicles, industrial processes and vegetative burning. In contrast, the coarse fraction of PM10 is associated with mechanical processes, such as wind erosion, breaking ocean waves and grinding operations. The available data indicate that source contributions to primary PM emissions and precursor gases in Canada vary by province/territory and by region. Industrial sources provide a major contribution in most provinces, followed by non-industrial fuel combustion and the transportation sector. Forest fires and prescribed burning are the largest estimated sources of particulate matter in some provinces and in the territories. Long-range transport from industrial regions of the United States makes a major contribution to levels of particulate matter in some regions of Canada.

Concentrations of particulate matter typically vary by time of day, day of the week, season and year. Based on fixed-site monitoring of 24-hour concentrations in ambient air, long-term mean PM10 concentrations during the mid-1980s to mid-1990s ranged from 11 to 42 µg/m3 at urban sites and during the mid-1990s ranged from 11 to 17 µg/m3 at rural sites. The corresponding values for PM2.5 were 6.9 to 20.2 µg/m3 and 7.0 to 10.5 µg/m3, respectively. The values for both PM10 and PM2.5 are above estimated background levels, indicating that anthropogenic activities make an important contribution to ambient particulate matter loadings. On a national scale, average particulate matter concentrations decreased by approximately 2 to 3 percent annually between 1984 and 1995.

In numerous epidemiological studies from around the world, including Canada, positive associations have been observed between ambient levels of particulate matter (as PM10, PM2.5 or other particle metrics) and a range of health outcomes, including daily mortality, respiratory and cardiovascular hospitalizations, impaired lung function, adverse respiratory symptoms and medication use, restricted activity days and the frequency of reported chronic respiratory disease. These associations could not be explained by the influence of weather, season, yearly trends, day-to-day variations or variations due to holidays, epidemics or other non-pollutant factors. While the populations studied were always exposed to other air pollutants in addition to particulate matter, associations of a similar magnitude were observed across numerous locations with differing air pollutant mixtures, and the association with particulate matter remained in analyses that adjusted for the effects of various other pollutants. These particulate matter-related health effects were observed at ambient concentrations that currently occur in Canada.

Therefore, the epidemiological evidence for mortality and morbidity in response to current levels of particulate air pollution meets a number of the criteria for causality, including consistency, dose-response relationship, coherence, temporal relationship and specificity of both outcome and agent. With respect to the biological plausibility of the association, the results of experimental studies in animals and humans provide some limited support for the epidemiological findings. However, both animal and experimental human work are constrained by the technological difficulties in reproducing environmentally relevant particulate matter and this work has generally been conducted at high levels with artificial particles. Some of this work, specifically the most recent work with concentrated ambient particles, has provided initial evidence of particulate matter-induced effects on the cardiorespiratory system, particularly in individuals with pre-existing respiratory and cardiovascular disease, and have provided preliminary indications of possible mechanisms. The database supports, therefore, a causal relation between current ambient PM10 and PM2.5 exposure and adverse health effects and provides a reasonable basis for preventive action.

Based principally on the sufficient weight of evidence of mortality and morbidity in the general population exposed to ambient concentrations of PM10 and PM2.5 examined in recent extensive epidemiological analyses in Canada and in other countries (at ambient concentrations currently occurring in Canada), as well as on some limited supporting data in experimental animal and controlled human exposure studies, PM10 and particularly PM2.5 are considered to be 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. Therefore, PM10 and particularly PM2.5 are considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Based on available data on the health effects of particulate matter, investigations of options to reduce exposure to particulate matter should be focused on the fine fraction (PM2.5). They should also be designed to reduce mid-range (24-hour average) rather than peak (i.e., <24-hour periods) exposures, since, on the basis of available data, 24-hour average exposure is associated with increases in mortality and morbidity.

The available data clearly indicate that relative source contributions to PM10 and PM2.5 vary by province/territory and by region. There are ongoing initiatives in risk management designed to accommodate these regional variations. Under the Canada-wide Standards subagreement of the Harmonization Accord signed by the Environment Ministers in January 1998, federal and provincial/territorial governments will develop numerical air quality standards for PM10 and PM2.5, with each jurisdiction developing a plan of action to achieve the standards in a specified time frame. Any investigations of options to reduce exposure as a result of the assessment of particulate matter as a Priority Substance under CEPA 1999 will complement those for this ongoing initiative.

The conclusion of this assessment is based on estimated and measured ambient levels of PM10. However, the assessment acknowledges that this substance can be emitted directly into the atmosphere or formed secondarily from precursors as a result of physical or chemical transformations. It is recommended that stakeholders be consulted on the need to add precursors to PM10 to the List of Toxic Substances in Schedule 1 and on the form of the Schedule 1 listing.

Notice therefore is hereby given that the Ministers of the Environment and of Health intend to recommend to Her Excellency the Governor in Council that 1,3-butadiene be added to the List of Toxic Substances in Schedule 1 to the Canadian Environmental Protection Act, 1999.

Annex

Summary of the Report of the Assessment of the substance 1,3-butadiene specified on the Priority Substances List

1,3-butadiene is a product of incomplete combustion resulting from natural processes and human activity. It is also an industrial chemical used primarily in the production of polymers, including polybutadiene, styrene-butadiene rubbers and latexes, and nitrile-butadiene rubbers. 1,3-butadiene enters the Canadian environment from exhaust emissions from gasoline- and diesel-powered vehicles, from non-transportation fuel combustion, from biomass combustion and from industrial on-site uses. The total amount of 1,3-butadiene entering the Canadian environment was estimated to range from 13 000 to 42 000 tonnes in 1994, mostly into air.

While 1,3-butadiene is not persistent, it is ubiquitous in the urban environment because of its widespread combustion sources. The highest atmospheric concentrations have been measured in air in cities and close to an industrial source. Given its sources of entry into the environment, its environmental fate and concentrations measured in Canada, the environmental assessment focussed on assessing the potential risks to aquatic life, terrestrial plants, terrestrial wildlife and soil invertebrates. The potential risks were assessed assuming worst-case, hyperconservative conditions. Analyses indicate that environmental biota are unlikely to be at risk even under such conditions.

Because of its non-halogenated nature and moderate environmental concentrations, 1,3-butadiene is not associated with stratospheric ozone depletion or with climate change. 1,3-butadiene is a contributor to the formation of ground-level ozone and resulting smog formation.

The general population in Canada is exposed to 1,3-butadiene primarily through ambient and indoor air. Inhaled 1,3-butadiene is carcinogenic in both mice and rats, inducing tumours at multiple sites at all concentrations tested in all identified studies. In addition, 1,3-butadiene is genotoxic in both somatic and germ cells of rodents. The greater sensitivity in mice than in rats to induction of these effects by 1,3-butadiene is likely related to species differences in metabolism to active epoxide metabolites. An association between exposure to 1,3-butadiene in the occupational environment and leukaemia fulfils several of the traditional criteria for causality; there is also some limited evidence that 1,3-butadiene is genotoxic in exposed workers. Therefore, in view of the weight of evidence of available epidemiological and toxicological data, 1,3-butadiene is considered highly likely to be carcinogenic in humans; it is also considered likely to be genotoxic in humans. 1,3-butadiene also induced adverse effects in the reproductive organs of female mice at relatively low concentrations.

Based on the information available, it is concluded that 1,3-butadiene 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. However, 1,3-butadiene is concluded to be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger to the environment on which life depends and a danger in Canada to human life or health. Therefore, 1,3-butadiene is considered to be "toxic" as defined in section 64 of the Canadian Environmental Protection Act, 1999.

1,3-butadiene may contribute, along with other reactive volatile organic chemicals, to the photochemical formation of ground-level ozone. It is recommended that key sources of 1,3-butadiene be addressed, therefore, as part of management plans for volatile organic chemicals that contribute to the formation of ground-level ozone.

Based on comparison of estimates of exposure for the general population with the tumorigenic potency, the priority to investigate options to reduce exposure to 1,3-butadiene in ambient air both in the vicinity of the identified point sources and from more dispersive non-point sources (identified herein primarily as transportation) is considered to be high. Investigation of concentrations and potential sources of 1,3-butadiene in indoor air may also be warranted.

Food and Drug Regulations — Amendments

Interim Marketing Authorization

Imidacloprid is registered under the Pest Control Products Act as an insecticide for the control of Colorado potato beetles, aphids and other insect pests on apples, potatoes and tomatoes. Maximum Residue Limits (MRLs) have been established under the Food and Drugs Act for residues of imidacloprid and its metabolites resulting from its use in Canada and other countries at 6 parts per million (ppm) in tomato paste, 3.5 ppm in brassica crops and lettuce, 3 ppm in tomato purée, 1.5 ppm in grapes, 1 ppm in peppers, tomatoes and tomato juice, 0.6 ppm in pears, 0.5 ppm in apples, 0.3 ppm in potatoes, 0.2 ppm in mangoes and 0.05 ppm in canola oil and cottonseed oil. By virtue of subsection B.15.002(1) of the Food and Drug Regulations, the MRL for other foods is 0.1 ppm.

The Pest Management Regulatory Agency (PMRA) of Health Canada has been requested to establish an MRL for residues of imidacloprid and its metabolites in citrus fruits, in order to permit the import and sale of citrus fruits containing these residues.

Before making a decision regarding a new MRL for a pest control product, the PMRA conducts the appropriate risk assessment. The MRL will be established if the data requirements for assessing safety have been adequately addressed and the evaluation indicates that the human health risks associated with the MRL are acceptable.

After the review of all available data, the PMRA has determined that an MRL for imidacloprid, including metabolites, of 1 ppm in citrus fruits would not pose an unacceptable health risk to the public.

Therefore, it is the intention of the PMRA to recommend that the Food and Drug Regulations be amended to establish an MRL for imidacloprid, including metabolites, of 1 ppm in citrus fruits.

This regulatory amendment will contribute to a safe, abundant and affordable food supply by allowing the importation and sale of food commodities containing acceptable levels of pesticide residues.

As a means to improve the responsiveness of the regulatory system, an Interim Marketing Authorization is being issued to permit the immediate sale of citrus fruits with an MRL for imidacloprid, including metabolites, of 1 ppm while the regulatory process to amend the Regulations is undertaken.
