The Ministry is moving forward on developing updated air standards for sulphur dioxide in 2016. This substance was identified as a priority for updating in the Ministry’s standard plan and the Ministry has worked with the federal government and other provinces and territories on a new Canadian Ambient Air Quality Standard (CAAQS) through the Air Quality Management System. The science reviewed in the development of the CAAQS will inform the Ministry’s update to its air standard. The Ministry is about to engage in pre-consultation on this substance.
The Ministry’s consultation process, designed in consultation with stakeholders, involves two steps:
Step one: ‘Pre-consultation’.
This step involves providing a ‘science discussion document’ by e-mail to interested parties for a standard under development, and subsequently holding a science discussion meeting with these interested parties. The science discussion document contains a comprehensive discussion on the scientific considerations for the derivation of a regulatory limit, but does not propose a regulatory limit. Interested parties will also be encouraged to submit written comments within two weeks following the science discussion meeting.
Step two: formal public consultation on the Ministry’s proposed air standards for sulphur dioxide.
This involves posting a Notice of Proposal on the Environmental Registry for new sulphur dioxide standards supported by a detailed scientific rationale document.
The rationale document will have considered the critical comments from stakeholders received during the pre-consultation stage. Posting on the Environmental Registry would be for up to 60 days, during which time the public would submit written comments. The Ministry may offer an additional substance-specific science meeting where there appears to be an interest among stakeholders.
