The Canadian Department of the Environment has published Significant New Activity Notices for nanoscale forms of aluminate, magnesium (2:1) and vanadate, magnesium (2:1). The reporting guidelines for both state that 'a significant new activity is...any use where the substance is engineered to contain particles of particle size 1 to 100 nanometres in one or more dimensions, in a quantity greater than 10kg in any one calendar year'. In the case of vanadate, a new use also applies in the case where it is used 'in a quantity greater than 100kg in any one calendar year: as a fuel additive; or as a component of engine emissions control equipment'.
Those engaging in a new use must therefore inform the authorities of the following information 'at least 90 days before...commencement' of the activity:
- 'A description of the proposed significant new activity in relation to the substance'
- Various pieces of information relating to characterisation and identification specific to the exact nature of the activity
- 'The anticipated annual quantity of the substance to be used in relation to the...activity'
- 'If known, three sites in Canada where the greatest quantity of the substance, in relation to the significant new activity, is anticipated to be used or processed and the estimated quantity by site'
The note states that information provided to the department 'will be assessed within 90 days after the day on which it is received'.
