Dear Minister Stewart:
RE: Sulphur in Gasoline and Diesel Fuel
I am writing to urge the federal government to immediately adopt stringent uniform
national standards for sulphur in gasoline and diesel. In particular, we urge the
government to immediately adopt a 30 parts per million maximum average sulphur content
standard for gasoline; and move quickly in adopting low sulphur standards for off-road
diesel.
Scientific Evidence Supports a 30 ppm Standard
With regard to the standard for gasoline the analysis by the Government Working
Group on Sulphur in Gasoline and Diesel clearly shows that the benefits of a 30 ppm
standard far outweigh the costs. Indeed, recent scientific studies suggest that the
Government Working Group's estimates of human health benefits from a 30 ppm gasoline
standard are far too low. A recent study published in the Canadian Journal of Public
Health showed a strong relation between the human health effects and the mix of
sulphur dioxide, nitrogen dioxide and carbon monoxide to which Canadians are exposed in
most urban areas. It is my understanding that these effects were not considered in
analyzing the pros and cons of more stringent sulphur standards. This suggests that the
benefits of lowering sulphur were likely significantly under-estimated.
Adoption of a Standard should not be delayed to match fuel requirements for US Tier
2 vehicles.
In 1995, the Canadian Council of Minister of the Environment, responding to the
recommendations of its Clean Vehicle and Fuel Task Group, asked Environment Canada to
recommend, by January 1, 1997, a maximum sulphur content for gasoline to come into effect
by January 2000. Although WCEL recognizes that failure to make the first deadline may make
the latter impracticable, we strongly urge the federal government to adopt a standard that
comes into affect on January 1, 2002 or earlier.
The suggestion by the Canadian Petroleum Products Institute that any new standard
should match fuel requirements for US Tier 2 vehicle standard is an insupportable delay
tactic. First and foremost, the direct emission effects of sulphur in gasoline, regardless
of effects caused by damage to emission control systems, justify lowering sulphur content
to 30 ppm. Given this justification, there is no need to delay adoption of a 30 ppm
standard pending determination of whether it is needed to support future vehicle
technology. It might, however, cause unnecessary costs to the refining industry if Canada
adopted a 150 ppm standard now, only to replace it with a 30 ppm standard once the needs
of future vehicle emissions technology became clear. The solution is clear: adopt a 30 ppm
standard now.
Second, tying Canadian gas standards to the needs of Tier 2 vehicles ignores the fact
that the Tier 2 vehicle standard -- which cannot be adopted until 2004 or later -- is
being supplanted by the National Low Emission Vehicle Standard. It is illogical to hinge
Canadian gas standards on a US vehicle standard which is becoming irrelevant.
Indeed, available data shows that, for low emission vehicles (LEVs) effects of sulphur
on the emission control systems may be permanent. These vehicles are already being sold on
the market and become the North American standard (and BC's legal standard) in model year
2001. Sulphur in gasoline may already be causing permanent degradation of the emission
control systems of Canadian cars, and this is likely to become more significant over the
next few years. Immediate action is needed to guard against any such degradation of
emission control systems. (Please note, based on analysis of available information, WCEL
is not convinced this degradation is sufficient to excuse motor vehicle manufacturers from
introduction of LEVs into the Canadian market).
Uniform National Standards are needed to Protect All Canadians and Protect Canadian
Vehicles from Permanent Damage
It is imperative that standards be uniform national standards for several reasons.
First, the analysis by the Government Working Group and the study recently published in
the Canadian Journal of Public Health -- shows that air pollution is causing harm
to Canadians in most Canadian urban areas, not just those the lower Fraser Valley and
Windsor-Quebec Corridor.
Second, a uniform national standard will ensure the highest degree of air quality in
areas experiencing the most acute air quality problems, i.e. the Lower Fraser Valley and
Windsor Quebec corridor. As noted above, there is some evidence that damage to emission
control systems from sulphur is permanent. Since, vehicles typically move between areas
with acute air quality problems and other areas, lower standards in the other areas could
lead to damage to the emission control systems of vehicles used in poor air quality areas.
Low Sulphur Diesel Standard for Off-Road Use
We are disappointed by the recommendation of the Government Working Group regarding
delaying adoption of a low sulphur diesel standard pending further study. We urge
Environment Canada to work rapidly in adopting a low sulphur standard for off-road use.
Standards should be in form of a federal regulation applying to all fuel sold in
Canada
We urge the federal government to adopt standards that apply equally across Canada.
Federal regulation will avoid the need to duplicate efforts in 12 provincial and
territorial ministries of environment.
We also urge the federal government to apply standards for gasoline and diesel to all
fuel sold in Canada, not merely gasoline crossing inter-provincial or international
boundaries. The federal government has often limited its regulation of products to
regulation of products crossing borders in order to ensure the constitutionality. However,
two recent cases indicate that a uniform national standard is preferable. First, the
recent case of R. v. Hydro Quebec clearly establishes the federal
jurisdiction to set environmental protection standards for the nation without proving that
the issue is a matter of national concern or inter-provincial/international trade.
Second, a standard that applies to all gasoline sold avoids the possibility of annoying
(although according to our analysis groundless) challenges to the federal action under
NAFTA similar to those launched by Ethyl Corporation in response to the federal ban on
inter-provincial and international trade in manganese based fuel additives.
We trust the above comments will be helpful and would be happy to discuss them with you
further.
Yours truly,
