There’s a page for guidelines for petitions to the Senedd
https://senedd.wales/senedd-business/petitions/standards-for-petitions/
and here
https://petitions.senedd.wales/rules
This is the closest example in topic that i can find on the recent petitions page, regarding the Usk. If you look at the rejection notes it was decided that the actions planned by DC and plans by the Rural Affairs group were enough.
So we need to really think about the wording and what angle we want to take.
And I’m sure we could get a lot more than 1612 signatures
