22 business days is pretty quick, hopefully it's straightforward. That would suggest approval July rather than September imo.

Assessment process

Once you have submitted your pilot project licence application, we’ll assess it against the environmental requirements in the Act.

We will also consider any public comments received and your responses to them. We expect you to have already engaged and considered the impact to the community. We will review your application for evidence of the community engagement you have performed.

We need to decide on acomplete pilot project licence application within 22 business days of receiving it. However, this timeframe can change if we need additional information to make a decision.
