I don't know for sure, but my guess would be for transparency and for documentation for the future.

In Canada projects that get submitted to BAPE and validated via the BAPE process have the government seal of approval and citizens groups tend to not challenge the findings, so I think perhaps Sayona would like the government to give its approval to avoid any challenges down the line from environmental groups. On the other hand having a document from the Government that says "BAPE is not required because your project has very little environmental impact" is just as powerful.

Either way the outcome should be a document from the government that can be used for if an environmental challenge is raised in the future.
