Without sufficient evidence to show that increased biomass in conventional gasoline and diesel is safe for vehicles, consumers, and our environment, the Government of Canada should delay moving ahead on an E15, or higher, mandate for gasoline until all studies are complete regarding the potential impact of these blends upon the current fleet and on future vehicles, both in Canada and the U.S. Similarly, before any new boutique additive or component is introduced into Canada’s fuelling infrastructure, or indeed the on-road fleet, our companies expect that at a minimum, a potential new additive would be registered with the U.S. EPA and hav ...[+++]e successfully completed all relevant tests and extensive third party validation covering factors including human health effects, toxicity, fuel distribution system durability and impact, catalyst and engine durability, as well as the finished fuel shelf life and storage.

The information shall also include, where appropriate, delayed, immediate and chronic effects from short- and long-term exposure: for example sensitisation, narcosis, carcinogenicity, mutagenicity and reproductive toxicity (developmental toxicity and fertility).

Generally, testing requirements at the lower volumes (10 kg to 1 t) focus on acute hazards (immediate or slightly delayed effects after short term exposure) while those at the higher tonnage levels include more expensive studies on the effects of (sub-) chronic exposure, on reproductive toxicity and on carcinogenicity.
